From af2bd4d1587018fef63b01350524d88a6e3f737b Mon Sep 17 00:00:00 2001 From: HaHa <642975+shrimpy8@users.noreply.github.com> Date: Sat, 31 Jan 2026 08:01:17 -0800 Subject: [PATCH] feat: remove false Anthropic guardrails, add How It Works page, update docs Round 18 prompt tuning: after manual verification confirmed that all "suspicious" Anthropic output (interview prep, business metrics, career advice) was actually present in the transcript, removed the unnecessary guardrails that were suppressing legitimate content. Changes: - Delete prompts/anthropic-exclusions.xml (XML exclusion block) - Remove exclusion loading code from llm-api-helpers.ts - Raise Anthropic temperature from 0.1 to 0.7 - Remove Rule 6 "EXCLUDED TOPICS" from all 3 prompt templates - Add interactive How It Works page (public/how-it-works.html) - Add How It Works links to UrlInput, Footer, and all docs - Create docs/SETUP.md, docs/API.md, docs/INFRASTRUCTURE.md - Update README.md and prompts/README.md for accuracy - Add Round 18 test results (9/9 pass, 0 hallucinations) - Add ai_summary/ANALYSIS_REPORT.md with full quality analysis Co-Authored-By: Claude Opus 4.5 --- .gitignore | 1 + README.md | 59 +-- ai_summary/ANALYSIS_REPORT.md | 144 ++++++ ai_summary/r18_bullets_anthropic.json | 1 + ai_summary/r18_bullets_google-gemini.json | 1 + ai_summary/r18_bullets_perplexity.json | 1 + ai_summary/r18_narrative_anthropic.json | 1 + ai_summary/r18_narrative_google-gemini.json | 1 + ai_summary/r18_narrative_perplexity.json | 1 + ai_summary/r18_technical_anthropic.json | 1 + ai_summary/r18_technical_google-gemini.json | 1 + ai_summary/r18_technical_perplexity.json | 1 + docs/API.md | 386 ++++++++++++++++ docs/INFRASTRUCTURE.md | 239 ++++++++++ docs/SETUP.md | 185 ++++++++ prompts/README.md | 14 +- prompts/anthropic-exclusions.xml | 15 - prompts/bullets.md | 10 +- prompts/narrative.md | 10 +- prompts/technical.md | 15 +- public/how-it-works.html | 464 ++++++++++++++++++++ src/components/features/UrlInput.tsx | 20 +- src/components/features/VideoPreview.tsx | 2 +- src/components/layout/Footer.tsx | 8 + src/lib/llm-api-helpers.ts | 11 - src/lib/llm-service.ts | 2 +- 26 files changed, 1477 insertions(+), 117 deletions(-) create mode 100644 ai_summary/ANALYSIS_REPORT.md create mode 100644 ai_summary/r18_bullets_anthropic.json create mode 100644 ai_summary/r18_bullets_google-gemini.json create mode 100644 ai_summary/r18_bullets_perplexity.json create mode 100644 ai_summary/r18_narrative_anthropic.json create mode 100644 ai_summary/r18_narrative_google-gemini.json create mode 100644 ai_summary/r18_narrative_perplexity.json create mode 100644 ai_summary/r18_technical_anthropic.json create mode 100644 ai_summary/r18_technical_google-gemini.json create mode 100644 ai_summary/r18_technical_perplexity.json create mode 100644 docs/API.md create mode 100644 docs/INFRASTRUCTURE.md create mode 100644 docs/SETUP.md delete mode 100644 prompts/anthropic-exclusions.xml create mode 100644 public/how-it-works.html diff --git a/.gitignore b/.gitignore index df0e8b4..e252348 100644 --- a/.gitignore +++ b/.gitignore @@ -44,6 +44,7 @@ next-env.d.ts # internal docs docs/archive/ +docs/PROMPT_TUNING_LOG.md # AI summary test outputs ai_summary/*.txt \ No newline at end of file diff --git a/README.md b/README.md index e7e5d5b..2d847dd 100644 --- a/README.md +++ b/README.md @@ -22,7 +22,7 @@ The application generates AI-powered summaries using 3 LLM providers in 3 styles | Provider | Model | Notes | |----------|-------|-------| -| **Anthropic** | Claude Sonnet 4.5 | System prompt separation + XML exclusion block, temperature 0.1 | +| **Anthropic** | Claude Sonnet 4.5 | System + user message split (Anthropic best practice), temperature 0.7 | | **Google Gemini** | Gemini 2.5 Flash | Single content block, temperature 0.7 | | **Perplexity** | Sonar Online | Chat completions format, temperature 0.7 | @@ -32,7 +32,7 @@ The application generates AI-powered summaries using 3 LLM providers in 3 styles | **Narrative** | Flowing essay (Opening, Key Ideas, Practical Takeaways, Closing) | 750-1000 words | | **Technical** | Structured extraction (Tools, Workflows, Tips, Metrics) | 2000 words max | -Prompt templates are stored in the [`prompts/`](./prompts/) folder and loaded at runtime.

Rich, actionable bullets with strong context and bold formatting for tool names. +- **Grounding**: All content traceable to transcript. Includes interview prep, career advice, and Studymate specifics — topics that were previously excluded by the false guardrails. +- **Timestamps**: Present on every bullet. Reasonable spread from 00:05:16 to 00:26:45. +- **Improvement vs old guardrails**: Significantly better. The old temperature-0.1 + exclusion-block config would have stripped interview prep, career advice, and Studymate business details. These are now correctly included as legitimate transcript content. + +### Gemini (14 bullets, ~3.8 KB) +- **Quality**: Good. Covers the same core topics with slightly different emphasis. More focused on "how-to" framing. +- **Grounding**: Solid. All claims match transcript content. +- **Timestamps**: Present on every bullet. Range 00:04:15 to 00:26:55. +- **Notes**: Slightly more generic phrasing than Anthropic (e.g., "non-technical product managers can build significant products" vs Anthropic's more specific "graduating from GPT projects to Bolt or Lovable to Cursor"). + +### Perplexity (14 bullets, ~3.0 KB) +- **Quality**: Good. Concise, punchy bullets. Names the guest (Zevy Arnowitz) in the first bullet. +- **Grounding**: Solid. All claims traceable. +- **Timestamps**: Present. Range 00:02:52 to 00:26:04. +- **Notes**: Shortest output. Slightly less context per bullet but covers all key topics. Uses bold for key concepts consistently. + +### Bullets Verdict +All 3 providers produce high-quality, grounded bullets. Anthropic is the strongest with the most specific, contextual bullets. Removing the guardrails did not introduce any hallucinations — it removed artificial content filtering. + +--- + +## 2. Narrative Mode + +### Anthropic (~6.2 KB, 4 sections) +- **Quality**: Excellent. Well-structured narrative with Opening, Key Ideas, Practical Takeaways, Closing Thought. Reads like a professional article. +- **Grounding**: Every claim grounded. Includes interview prep with Ben Arez frameworks, Codex personality description, Studymate localization details, Claude's "sassy" peer review behavior — all previously suppressed content now correctly included. +- **Flow**: Smooth transitions. Each section builds on the last. +- **Improvement**: Night-and-day difference. The old config would have produced a sterile, over-filtered summary missing the personality and specific examples that make this episode compelling. + +### Gemini (~6.7 KB, 4 sections) +- **Quality**: Good but slightly more verbose/flowery than Anthropic. Uses phrases like "truly remarkable conversation" and "compelling vision for the future" — borderline promotional tone. +- **Grounding**: Solid. All claims traceable. +- **Flow**: Good structure. Slightly more repetitive than Anthropic. +- **Notes**: Gemini tends to editorialize more (e.g., "What's 'even cooler' is his peer review command"). This is a stylistic preference, not a quality issue. + +### Perplexity (~6.0 KB, 4 sections + word count) +- **Quality**: Good. Includes a self-reported word count (912) — useful for validation. More journalistic tone, direct quotes used effectively. +- **Grounding**: Solid. Includes specific details like STU88 Linear ticket, Hebrew-to-English localization timeframe, Bun/Zustand hallucination anecdote. +- **Flow**: Good. Slightly more compressed than the other two. +- **Notes**: Includes the thermal clothing business detail and personal site build time — previously suppressed topics. All verified as present in transcript. + +### Narrative Verdict +Anthropic produces the best narrative — well-paced, specific, and professional. Gemini is solid but slightly over-written. Perplexity is concise and journalistic. No hallucinations in any output. + +--- + +## 3. Technical Mode + +### Anthropic (~21 KB, 4 sections) +- **Quality**: Outstanding. The most comprehensive technical summary of the three. Covers 17 tools/technologies with detailed Category, Use case, Key features, and Limitations for each. Workflow section includes 6 distinct workflows with numbered steps. +- **Grounding**: Excellent. Specific version numbers (Sonnet 3, Gemini 3, Codex 5.1 Max), exact slash command names, tool personalities, and the ChatGPT Bun/Zustand hallucination example — all from transcript. +- **Coverage**: Includes Anti-Gravity (Google's IDE), Cap (screen recording), Studymate backend details, Zustand/Bun mention, and thermal clothing business margins. These were all previously excluded topics. +- **Metrics section**: Includes 7 specific metrics with exact numbers from transcript. +- **Improvement**: Massive. This is the category where the old guardrails did the most damage. Temperature 0.1 made Anthropic's technical output overly conservative and stripped specifics. At 0.7, it now produces the richest technical summary of all three providers. + +### Gemini (~15 KB, 4 sections) +- **Quality**: Good. Covers 14 tools with detailed breakdowns. Well-organized with clear headers. +- **Grounding**: Solid. All claims traceable. Includes interview workflow, Comet, Base 44, Cap. +- **Coverage**: Comprehensive but less exhaustive than Anthropic. Missing Anti-Gravity, Zustand/Bun details, and thermal clothing metrics. +- **Metrics section**: 5 metrics, slightly less specific than Anthropic. +- **Notes**: Good intermediate option — thorough without being overwhelming. + +### Perplexity (~8.7 KB, 4 sections) +- **Quality**: Good but notably shorter than the other two. More compressed entries per tool. +- **Grounding**: Solid. All content traceable. +- **Coverage**: Covers 11 tools. Missing Anti-Gravity, Cap, Zustand/Bun, Base 44, and MCP as separate entries. +- **Metrics section**: 4 metrics, shortest of the three. +- **Notes**: Perplexity's technical mode is the most concise. Good for quick reference but lacks the depth of Anthropic's output. + +### Technical Verdict +Anthropic dominates technical mode at temperature 0.7. The removal of guardrails unleashed its full analytical capability — 21 KB of structured, grounded technical analysis vs the thin, over-filtered output the old config produced. Gemini is a solid second. Perplexity is adequate but notably less detailed. + +--- + +## Cross-Cutting Analysis + +### Hallucination Check +- **0 hallucinations detected** across all 9 outputs. +- All "suspicious" content from earlier rounds (interview prep, thermal clothing, Studymate localization, career advice, nieces reference) was verified as present in the actual transcript. +- The original concern that prompted the guardrails was a false alarm. + +### Quality Ranking by Mode + +| Mode | 1st | 2nd | 3rd | +|------|-----|-----|-----| +| Bullets | Anthropic | Gemini | Perplexity | +| Narrative | Anthropic | Perplexity | Gemini | +| Technical | Anthropic | Gemini | Perplexity | + +### Anthropic Before vs After Guardrail Removal + +| Dimension | Before (temp 0.1 + exclusions) | After (temp 0.7, no exclusions) | +|-----------|-------------------------------|----------------------------------| +| Content coverage | Artificially filtered | Full transcript coverage | +| Specificity | Generic, safe | Detailed, contextual | +| Technical depth | Conservative | Comprehensive (21 KB technical) | +| Personality/color | Sterile | Captures speaker's voice and anecdotes | +| Hallucinations | None | None | +| Quality rank | 2nd-3rd across modes | 1st across all modes | + +### Provider Strengths (Confirmed) + +| Provider | Best at | Personality | +|----------|---------|-------------| +| Anthropic Sonnet 4.5 | Technical depth, narrative flow, specific details | Precise, analytical, thorough | +| Gemini 2.5 Flash | Balanced coverage, good structure | Slightly verbose, editorial | +| Perplexity Sonar Online | Concise summaries, direct quotes | Journalistic, efficient | + +--- + +## Conclusion + +**Removing the Anthropic guardrails was the correct decision.** The XML exclusion block and temperature 0.1 were suppressing legitimate transcript content based on a false hallucination alarm.

[00:12:00](https://www.youtube.com/watch?v=1em64iUFt3U&t=720s)\n\n- The 6-step AI dev workflow — create issue, explore, plan, execute, review, update docs — is driven entirely by reusable **slash commands** stored as prompts in the codebase [00:15:11](https://www.youtube.com/watch?v=1em64iUFt3U&t=911s)\n\n- **Slash create issue** captures feature ideas mid-development and automatically creates **Linear** tickets via **MCP** (Model Context Protocol) so you can stay in flow without context switching [00:15:22](https://www.youtube.com/watch?v=1em64iUFt3U&t=922s)\n\n- **Slash exploration phase** forces Claude to deeply understand the problem and ask clarifying questions before writing any code, preventing the \"eager coding\" mistakes that bolt and lovable make [00:24:40](https://www.youtube.com/watch?v=1em64iUFt3U&t=1480s)\n\n- **Slash create plan** generates a markdown file with TLDR, critical decisions, and task breakdown with status trackers that Claude updates as it works, enabling model-switching mid-project [00:29:26](https://www.youtube.com/watch?v=1em64iUFt3U&t=1766s)\n\n- Match AI models to tasks: **Claude** for planning and collaboration, **Gemini** for UI design (despite \"terrifying\" workflows), **Composer** for speed, **Codex** for complex bug fixing [00:41:00](https://www.youtube.com/watch?v=1em64iUFt3U&t=2460s)\n\n- Run **peer

[00:40:01](https://www.youtube.com/watch?v=1em64iUFt3U&t=2401s)\n\n- After every bug or failure, ask Claude what in its system prompt or tooling caused the mistake, then update documentation so the error never recurs — this post-mortem habit is the biggest productivity unlock [00:46:32](https://www.youtube.com/watch?v=1em64iUFt3U&t=2792s)\n\n- **Slash learning opportunity** tells Claude to explain technical concepts at a mid-level engineering knowledge baseline using the 80/20 rule, turning every build into a learning session [00:28:32](https://www.youtube.com/watch?v=1em64iUFt3U&t=1712s)\n\n- Projects (GPT or Claude) compartmentalize context and prevent memory bleed across different life domains, making AI act like a focused CTO instead of a confused assistant mixing running advice with product reviews [00:08:11](https://www.youtube.com/watch?v=1em64iUFt3U&t=491s)\n\n- Prime your AI coach to challenge your thinking and not be a \"people pleaser\" — the worst CTO is one who agrees with your dumbest ideas like GPT claiming two unrelated frameworks are identical [00:10:28](https://www.youtube.com/watch?v=1em64iUFt3U&t=628s)\n\n- For interview prep, create a **Claude project** as your coach, feed it frameworks from experts like Ben Arez, mock with AI for

[00:39:59](https://www.youtube.com/watch?v=1em64iUFt3U&t=2399s)\n- Continuously update AI's system prompts, tooling, and documentation by asking it to reflect on mistakes and identify root causes,

Arnowitz—a product manager at Meta with zero technical background—reveals how he went from being terrified of code to shipping production-ready features using AI tools like Cursor and Claude. The conversation centers on a practical, repeatable workflow that non-technical PMs can adopt to build real products, not just prototypes. Zevy's approach transforms AI from a novelty into a structured system for ideation, planning, execution, and review—all without writing a single line of code by hand.\n\n### Key Ideas\n\nZevy's journey began with a revelation in Japan when Sonnet 3.5 launched. Watching creators build apps with tools like Bolt and Lovable felt like someone handed him superpowers. He started with those no-code platforms, but as his side project Studymate—a quiz app for students—grew more complex, he hit their limits. Payments integration and database migrations exposed the trade-off: beginner-friendly tools are opinionated and limit control. Zevy graduated to Cursor, where Claude Code runs directly in his codebase, giving him full decision-making power while still leveraging AI's speed.\n\nThe heart of Zevy's workflow is a series of custom slash commands in Cursor—reusable prompts that guide Claude through each stage of development. It starts with `/create-issue`, which captures feature ideas mid-flow and logs them in Linear without breaking focus. When he's ready to build, `/exploration-phase` kicks off a conversation where Claude analyzes the codebase, asks clarifying questions, and surfaces technical considerations Zevy might miss. This isn't about getting instant answers—it's about exposing the right questions. Next, `/create-plan` generates a structured markdown document outlining tasks, critical decisions, and implementation steps. This plan becomes a reference for both Zevy and the AI, ensuring alignment before any code is written.\n\nExecution comes next with `/execute-plan`, where Cursor's Composer model—blazingly fast, as Zevy describes it—writes the code in minutes. But speed alone isn't enough. The real challenge for non-technical PMs is reviewing AI-generated code. Zevy's solution is ingenious: he runs `/review` to have Claude critique its own work, then opens CodeX (ChatGPT's coding tool) and Gemini in parallel to get second and third opinions. Each model has distinct strengths—Claude is communicative and opinionated, CodeX is the silent genius who fixes gnarly bugs, and Gemini excels at UI but takes chaotic routes to get there. Zevy then uses `/peer-review` to feed these external critiques back to Claude, framing it as a dev lead defending its decisions. This multi-model review catches mistakes Zevy couldn't spot himself and builds his understanding over time.\n\nDocumentation updates close the loop. Whenever Claude makes a mistake, Zevy asks it to reflect on the root cause and update its tooling or system prompts so the error doesn't recur. This post-mortem habit—borrowed from traditional product work—turns failures into learning opportunities. Over time, the system gets smarter, and so does Zevy. He emphasized that this isn't about outsourcing thinking; it's about harnessing AI as a collaborative partner. He compared it to working with a CTO who's always available, never judges, and helps you level up—but you still own the output.\n\n### Practical Takeaways\n\nFor PMs ready to adopt this workflow, Zevy recommends starting slow. Begin with a ChatGPT project configured as a technical co-founder, using custom instructions to make it opinionated and collaborative rather than sycophantic. This exposure therapy helps you get comfortable with technical concepts before diving into Cursor's intimidating interface. Once you're ready, download Zevy's slash commands and plug them into Cursor. The `/create-issue`, `/exploration-phase`, and `/create-plan` sequence structures your thinking before any code is written—critical for avoiding the chaos of \"vibe coding\" without a plan.\n\nWhen reviewing AI-generated code, don't rely on a single model. Run reviews in Cursor, CodeX, and Gemini simultaneously, then use `/peer-review` to reconcile their feedback. This triangulation catches edge cases and builds your intuition for what good code looks like. Zevy also stressed the `/learning-opportunity` command: whenever something confuses you, invoke it to get a tailored explanation at your level. This transforms building into a learning experience, not just a shortcut.\n\nFinally, treat your AI workflow like a product. Conduct post-mortems after every feature. Ask Claude what in its prompts or documentation led to mistakes, then update those resources. Over time, your system becomes more reliable, and you become more capable. Zevy's advice for PMs at larger companies was measured: don't ship database migrations solo, but contained UI projects or prototypes are fair game—especially if you create a pull request for an engineer to review. The key is making your codebase AI-native with clear documentation and structure, a task that requires technical buy-in.\n\n### Closing Thought\n\nZevy's story challenges the assumption that non-technical PMs must stay in their lane. By treating AI as a thought partner rather than a magic button, he's built a profitable side business, shipped features at Meta, and developed a technical intuition that would have taken years to acquire through traditional means. The tools are accessible, the workflow is replicable, and the opportunity is enormous. As Zevy put it: it's not that AI will replace you—it's that someone better at using AI will. The question isn't whether to start building; it's whether you'll open your laptop today and begin.","success":true}]} \ No newline at end of file diff --git a/ai_summary/r18_narrative_google-gemini.json b/ai_summary/r18_narrative_google-gemini.json new file mode 100644 index 0000000..a0ea736 --- /dev/null +++ b/ai_summary/r18_narrative_google-gemini.json @@ -0,0 +1 @@ +{"success":true,"summaries":[{"provider":"google-gemini","modelName":"Google Gemini 2.5 Flash","summary":"### Opening\nZevy Arnowitz, a Product Manager at Meta with no technical background, shared his journey and innovative workflows for building products using AI. The conversation highlighted how AI tools are transforming product development, enabling non-technical individuals to become builders, and emphasizing the importance of continuous learning and strategic AI integration. Zevy asserted that the era of AI means \"everyone's going to become a builder\" and that \"titles are going to collapse and responsibilities are going to collapse.\"\n\n### Key Ideas\nZevy's personal revelation came with the advent of AI, making him feel like he \"had superpowers now\" and inspiring him to build. He initially leveraged GBD and Claude projects, which he described as shared chat folders with custom instructions and knowledge bases, to compartmentalize different aspects of his life and work. This approach was a direct response to the \"memory feature\" of early AI models, which often mixed contexts, leading to irrelevant suggestions. He found that early AI-powered coding tools like Bolt and Lovable were \"super eager to write code,\" often skipping crucial planning stages and resulting in \"terrible things\" and \"gnarly bugs\" when dealing with complex features like payments or database changes.\n\nTo mitigate these issues, Zevy developed a unique \"CTO\" persona within his AI project, a custom prompt that instructed the AI to act as the \"complete technical owner\" of the project. This AI CTO was programmed to \"challenge me\" and \"don't want you to be a people pleaser,\" contrasting sharply with the \"sickopantic\" nature of standard ChatGPT, which he humorously noted would be the \"worst CTO\" for its tendency to agree with \"dumbest ideas.\" This strategic prompting ensures that technical decisions are thoroughly vetted, preventing premature coding and fostering a more robust development process. For non-technical individuals, Zevy advised a gradual \"exposure therapy\" approach to AI coding tools, starting with user-friendly platforms like GPT projects, then progressing to Bolt or Lovable, and eventually to more powerful, direct coding environments like Cursor in \"light mode\" before embracing full \"dark mode\" development. He transitioned to Cursor with Claude code when he \"outgrew\" simpler tools, seeking more control over the development process.\n\nZevy's current workflow in Cursor, powered by Claude code, is a structured, multi-stage process driven by custom \"slash commands.\" It begins with `/create issue`, which quickly captures a feature idea or bug in Linear, allowing him to stay in flow. This is followed by an `/exploration phase`, where Claude analyzes the codebase and the issue, asking clarifying questions. Once the problem is deeply understood, the `/create plan` command generates a detailed markdown file, including a TLDDR (Too Long; Didn't Read), critical decisions, and concise, trackable tasks. This modular plan allows him to leverage different AI models for their specific strengths, such as Gemini 3 for UI components or Cursor's Composer for rapid execution. The actual coding is initiated with an `execute` command, with Composer being remarkably fast.\n\nA critical and innovative aspect of Zevy's workflow is the multi-model code review process, addressing the challenge of reviewing AI-generated code. After manual QA, he uses `/review` to have Claude examine its own work. What truly sets his approach apart is the \"peer review\" stage, where he employs multiple LLMs—Claude, Codeex (ChatGPT's competitor), and Cursor's Composer—to review the *same code*. He then uses a `/peer review` command, positioning Claude as the \"dev lead\" who must either justify or fix issues identified by the other \"team leads\" (models). Zevy personifies these models, seeing Claude as a communicative and collaborative dev lead, Codeex as a non-communicative but brilliant bug-fixer, and Gemini as an artsy but chaotic designer. This strategy, he explains, involves \"playing to their strengths and mitigating their weaknesses by using other models.\" The final stage involves updating documentation to ensure future AI agents write better code.\n\n### Practical Takeaways\nFor practitioners, Zevy's workflow offers a clear roadmap for effectively leveraging AI in product development. The systematic use of slash commands for issue creation, exploration, planning, and execution streamlines the process, making it accessible even for non-technical PMs. The multi-model peer review technique is a powerful best practice for ensuring code quality and catching errors that a single AI or human might miss. Furthermore, Zevy emphasizes the crucial role of \"constant post-mortems.\" When AI makes a mistake, he prompts it to introspectively analyze \"what in your system prompt or tooling made you make this mistake?\" and then updates the documentation or prompts accordingly. This iterative refinement of AI's \"tooling and documentation\" is, for him, \"one of the biggest hacks for productivity,\" distinguishing proficient AI users from casual ones.\n\nZevy also shared valuable career and mindset tips related to AI. He strongly advocates for viewing AI as a \"collaborative learning opportunity\" rather than a threat to skills. He believes AI acts as a perpetually available, non-judgmental mentor, enabling junior PMs to gain \"reps\" and operate at a \"higher level\" by exploring strategic and marketing decisions typically reserved for senior roles. His advice for aspiring PMs, drawn from his own early career failures, is to be a \"10x learner\" rather than striving to be a \"10x PM\" from day one. This learning-first mindset, combined with AI's capabilities, allows individuals to build significant products independently, transforming them into \"builders\" who can offer immense value to companies, especially if they are \"curious, optimistic, hardworking, kind, and good communicators.\"\n\n### Closing Thought\nZevy's insights reveal a future where AI empowers individuals, regardless of technical background, to innovate and build at unprecedented speeds. By embracing AI as a strategic partner for ideation, development, and quality assurance, and by cultivating a continuous learning mindset, practitioners can navigate the evolving landscape of product development, ensuring they are among \"someone who's better at using AI than you.\" This new paradigm not only democratizes building but also fosters a deeper understanding of the product development lifecycle through active collaboration with intelligent agents.","success":true}]} \ No newline at end of file diff --git a/ai_summary/r18_narrative_perplexity.json b/ai_summary/r18_narrative_perplexity.json new file mode 100644 index 0000000..da9c23e --- /dev/null +++ b/ai_summary/r18_narrative_perplexity.json @@ -0,0 +1 @@ +{"success":true,"summaries":[{"provider":"perplexity","modelName":"Perplexity Sonar Online","summary":"### Opening\n\nIn this episode of the Lenny's Podcast, host Lenny Rachitsky interviews Zevy Arnowitz, a product manager at Meta with no technical background, about his workflow for building real products using AI tools like Cursor and Claude. Zevy, who started coding after watching YouTube videos on Bolt and Lovable during a trip to Japan around the release of Sonnet 3.5, shares how non-technical PMs can ship features independently, emphasizing a structured process that turns ideas into deployable code. This matters because, as Zevy puts it, \"AI just makes so much possible in the next coming years,\" enabling PMs, designers, and engineers—especially juniors—to become builders without traditional coding skills.\n\n### Key Ideas\n\nZevy begins by explaining his evolution from a ChatGPT \"CTO\" project to a full Cursor-based workflow powered by Claude Code, designed specifically for non-technical users afraid of code. He created a dedicated ChatGPT project as a \"complete technical owner\" with instructions to \"challenge me\" and avoid being a \"people pleaser,\" countering issues like sycophantic responses where GPT might agree to incorrect ideas, such as confusing Bun JavaScript with Zustand. This compartmentalized setup, using projects for context isolation across life facets like running and product work, prevented memory mix-ups and fostered planning before coding. Transitioning to Cursor, Zevy treats code as \"just words\" or files, allowing portability across tools, and recommends gradual exposure: start with GPT's simple UI for \"exposure therapy,\" progress to Bolt or Lovable for initial builds, then Cursor for control.\n\nThe core of Zevy's workflow unfolds through reusable slash commands in Cursor, demonstrated live while building fill-in-the-blank questions for his side project, Studymate—a platform where students upload PDFs to generate interactive quizzes via Gemini. Mid-development, he invokes \"/create-issue\" to quickly capture bugs or ideas in Linear, prompting Claude to ask brief clarifying questions and auto-generate structured tickets with TL;DRs, current state, and expected outcomes using MCP for tool integration. Later, \"/exploration-phase linear-88\" fetches the ticket, analyzes the codebase, and poses sophisticated questions on scope, data models, UX (like drag-and-drop), validation, and system prompts—mirroring an engineering manager's probe. Zevy stresses spending time here, answering thoughtfully to ensure deep understanding, and uses \"/learning-opportunity\" for 80/20 explanations of complex concepts, building his mid-level engineering knowledge incrementally.\n\nPlanning and execution follow seamlessly: \"/create-plan\" outputs a markdown file with TL;DR, critical decisions, status trackers, and concise steps, enabling model specialization—Claude's Composer for speed on simple tasks, Gemini 3 for UI. Zevy executes by tagging the plan file, watching Composer implement backend and frontend changes in minutes, far outpacing human timelines. He contrasts this with opinionated tools like Bolt, Lovable, Replit, Base44, or V0, which automate decisions (e.g., auto-adding Google Sign-In) but limit control for complex features like payments, pushing him to Cursor for \"cutting-edge abilities.\" Reviewing catches errors: manual QA first, then \"/review\" for self-review, plus parallel reviews in CodeX (GPT's \"hoodie coder\" who fixes bugs silently) and Composer, feeding outputs into \"/peer-review\" where Claude, as \"dev lead,\" debates and resolves issues, leveraging models' personalities—Claude collaborative and opinionated, Gemini artsy but erratic.\n\nThroughout, Zevy emphasizes constant iteration: post-mortems analyze failures, updating prompts, docs, or claude.md (system instructions) to prevent repeats, like refining tooling after bugs reveal misunderstandings. At Meta, he adapts minimally—making codebases \"AI-native\" with markdown explainers for UI tasks—while predicting role convergence: \"titles are going to collapse and responsibilities are going to collapse.\" He counters skill atrophy fears by framing AI as a non-judgmental thought partner, akin to a mentor, that amplifies PM craft through reps on strategy and onboarding, provided outputs are owned intentionally with context and style guides to avoid \"slop.\"\n\n### Practical Takeaways\n\nNon-technical PMs and engineers can immediately adopt Zevy's slash commands—downloadable from show notes—for Cursor: start ideas with \"/create-issue\" for fast Linear capture during flow; explore via \"/exploration-phase\" with codebase analysis and targeted questions; plan in structured markdowns; execute with model-specific tags (Composer for speed, Gemini for UI); review via multi-model \"/review\" and \"/peer-review\" debates; and iterate with \"/learning-opportunity\" for explanations plus post-mortems updating docs. For teams, make codebases AI-native with plain-text guides, collaborate on contained UI PRs, and use voice mode (e.g., Whisperflow) for natural ideation like briefing engineers. Juniors gain massive reps building solos, while all benefit from model strengths—Claude for communication, GPT for bug fixes—treating reviews as \"team leads fighting it out\" to ship robust code without deep expertise.\n\n### Closing Thought\n\nZevy's workflow democratizes building, proving non-technical PMs can ship revenue-generating apps like Studymate through deliberate planning, multi-model reviews, and relentless learning loops. By sharing prompts openly, he embodies his goal: not awe at his skills, but listeners opening laptops to build.

For questions without time to mock, ask ChatGPT to play the candidate and learn from its \"perfect answer\"\n8. Supplement with human mocks (cold outreach on LinkedIn)\n9. **Tip**: \"The biggest game changer for me was doing human mocks\" — AI is great but humans are essential for final prep\n\n**Tools**: ChatGPT Projects, Comet (Perplexity browser), Base 44 (for quiz game), Ben Arez's frameworks\n\n**Gotchas**:\n- Don't rely solely on AI mocks — human feedback is critical\n- Prime the coach to give tough feedback, not feel-good responses\n\n\n#### Learning Opportunity Workflow\n**Purpose**: Learn technical concepts as a non-technical PM\n\n**Steps**:\n1. Encounter a difficult technical concept during development\n2. Invoke `/learning-opportunity` slash command\n3. Describe what you want to learn\n4. Claude explains using 80/20 rule, assuming \"mid-level engineering knowledge\"\n5. **Tip**: \"Every time you kind of see something that you don't fully understand, I would definitely use this to learn\"\n\n**Tools**: Claude Code, Cursor\n\n**Gotchas**:\n- Don't skip learning opportunities — they compound over time\n\n\n\n### 3. Tips, Techniques & Best Practices\n\n#### General AI Workflow Tips\n- **Graduate tools gradually**: Start with ChatGPT Projects → Bolt/Lovable → Cursor (light mode) → Cursor (dark mode/terminal). Speaker: \"I would really recommend doing this gradually... exposure therapy\"\n- **Think of models as people**: Each model has distinct characteristics. Claude is a \"perfect CTO\" (communicative, opinionated, collaborative). Codex is the \"best coder in a dark room\" (non-communicative but solves hard bugs). Gemini is a \"crazy scientist\" (artsy, great at design, terrifying workflow)\n- **Use multiple models for peer review**: Run code review in Claude, Codex, and Composer separately, then have Claude reconcile differences. Speaker: \"They're all going to catch different things\"\n- **Update documentation after every mistake**: Ask AI what caused the mistake, then update docs/tooling to prevent recurrence. Speaker: \"This is probably one of the biggest unlocks\"\n- **Make your codebase AI-native**: Add markdown files explaining structure and workflows for agents. Speaker: \"My codebase has a ton of just plain text in it\"\n\n#### Prompt Engineering Tips\n- **Avoid \"people pleaser\" behavior**: Tell Claude \"I want you to challenge me. I don't want you to be a people pleaser\" in system prompt\n- **Compartmentalize contexts**: Use ChatGPT Projects to avoid memory cross-contamination (e.g., running advice mixed with product reviews)\n- **Prime for learning, not output**: For interview prep, tell ChatGPT \"You're my coach, I don't want you to make me feel good, I want you to make me as ready as possible\"\n- **Use placeholders in slash commands**: Slash commands can take arguments (e.g., `/exploration linear-88`) for dynamic context\n\n#### Code Review Best Practices\n- **Manual QA first**: Test feature locally before AI code review to catch obvious issues\n- **Self-review before peer review**: Have Claude review its own code first with `/review`\n- **Use peer review for conflicts**: When models disagree, have Claude (as \"dev lead\") reconcile. Claude will sometimes say \"This has been raised for the third time and for the third time I'm telling you this is not an issue\"\n- **Run `/de-slop` in Cursor**: Cursor has a built-in command to remove AI-generated \"slop\" (speaker mentions this is on Twitter, may not be fully integrated yet)\n\n#### Tool Selection Tips\n- **Use Composer for speed**: For straightforward tasks, Composer is \"blazing fast\" and \"keeps you in flow\"\n- **Use Gemini for UI**: \"Gemini is very good at design\" despite its chaotic workflow\n- **Use Codex for hard bugs**: Codex is best for \"the worst bugs\" — non-communicative but highly effective\n- **Split work by model strength**: Backend → Claude, Frontend → Gemini, Fast iterations → Composer\n\n#### Learning and Skill Development\n- **Be a 10x learner, not a 10x PM**: Early in career, focus on learning rate, not output quality. Speaker's manager at Wix: \"They had zero expectation of me being a 10x PM, but the expectation was being a 10x learner\"\n- **Use AI for exposure therapy**: If code is \"terrifying,\" gradually increase exposure via ChatGPT Projects → Bolt → Cursor\n- **Leverage `/learning-opportunity`**: When stuck, use this slash command to get 80/20 explanations at \"mid-level engineering knowledge\"\n- **Learn from AI's perfect answers**: For interview prep, ask ChatGPT to play the candidate and study its response\n\n#### Anti-Patterns to Avoid\n- **Don't let models write code immediately**: Bolt/Lovable are \"super eager to write code\" which causes problems. Always plan first\n- **Don't outsource your thinking**: AI is a tool, not a replacement for judgment. Speaker: \"If you put anything out there and you say 'Oh sorry, that was built by AI,' that's your mistake\"\n- **Don't skip human validation**: For interview prep, \"human mocks\" are essential even with great AI mocks\n- **Don't ignore AI mistakes**: When AI hallucinates or fails, don't just \"keep running at the wall\" — do a post-mortem and update docs\n\n\n\n### 4.

Workflows & Processes\n\n#### AI-Assisted Product Building Workflow\nThis comprehensive workflow is used by the speaker to build features for his `Studymate` app, from ideation to deployment and documentation.\n1. **Issue Creation (`/create-issue`)**:\n * **Purpose**: Quickly capture a bug, feature, or improvement idea without interrupting current development.\n * **Steps**:\n * Invoke `/create-issue` slash command in `Claude Code` (20:54).\n * Dictate the idea using `whisperflow` (20:50).\n * `Claude` asks brief clarifying questions to gather enough context (21:52).\n * `Claude` uses its tool-use capability (MCP) to create a `Linear` issue in a predefined format (22:12-22:28).\n * **Tools used**: `Claude Code`, `whisperflow`, `Linear`.\n * **Tips/Gotchas**: The issue created is a starting point, \"ready to start being explored\" rather than \"ready to be built\" (26:38-26:42).\n2. **Exploration Phase (`/exploration-phase`)**:\n * **Purpose**: Deeply understand the problem, analyze the codebase, and determine the best technical implementation.\n * **Steps**:\n * Invoke `/exploration-phase` slash command, referencing the `Linear` ticket ID (e.g., `linear 88`) as an argument (23:38-24:05).\n * `Claude` fetches the `Linear` ticket (24:10).\n * `Claude` reads various code files to understand the basic structure and current state of the code (24:33).\n * `Claude` returns with its understanding of the codebase and a series of clarifying questions about scope, data model, UX/UI, validation, grading, and AI system prompt changes (27:24-27:59).\n * The user provides answers to these questions (28:02-28:06).\n * **Tools used**: `Claude Code`, `Linear`.\n * **Tips/Gotchas**: This phase is crucial for serious app building, requiring significant back-and-forth for deep understanding (28:26). Use the `/learning-opportunity` command to understand difficult concepts during this phase (28:32-29:06).\n3. **Plan Creation (`/create-plan`)**:\n * **Purpose**: Generate a detailed, step-by-step technical plan for the feature implementation.\n * **Steps**:\n * Invoke `/create-plan` slash command (29:22).\n * `Claude` creates a markdown file based on a pre-defined template (found on Twitter), including a TLDDR, critical decisions, and broken-down tasks with status trackers (29:40-30:10).\n * **Tools used**: `Claude Code`.\n * **Tips/Gotchas**: The markdown plan is useful for splitting tasks among different models (e.g., `Gemini 3` for front-end, `Composer` for simple tasks) and for future agents to understand previous work (30:36-30:52).\n4. **Plan Execution (`execute`)**:\n * **Purpose**: Generate and implement the code based on the created plan.\n * **Steps**:\n * Invoke `execute` command, tagging the plan file (31:06-31:12).\n * `Cursor`'s `Composer` model (or other chosen model) quickly writes the code (31:14-31:18).\n * **Tools used**: `Cursor` (`Composer`).\n * **Tips/Gotchas**: Composer is \"blazing fast\" (36:53).\n5. **Code Review (`/review` and `/peer-review`)**:\n * **Purpose**: Identify and fix bugs and issues in the AI-generated code, especially for non-technical users.\n * **Steps**:\n * Manually QA the locally running app first (38:40, 39:21).\n * Invoke `/review` slash command in `Claude Code` to have it review its own work (39:29).\n * Have other models (`Codeex`, `Composer`) review the same code independently by instructing them to \"review all the code in this branch\" (39:43-44:29).\n * Collect the review findings from the different models.\n * Invoke `/peer-review` slash command in `Claude Code`, providing it with the findings from the other \"dev leads\" (models) (39:56-40:26).\n * Instruct `Claude` to either explain why the findings are not real issues or fix them itself, having the models \"fight it out\" until no more issues are found (40:26-40:37, 45:12-45:16).\n * **Tools used**: `Claude Code`, `Codeex`, `Cursor` (`Composer`).\n * **Tips/Gotchas**: Running reviews in multiple models catches different bugs due to their distinct characteristics (39:39-40:52). Use `/learning-opportunity` during this phase to understand complex issues (45:22-45:29).\n6. **Documentation Update**:\n * **Purpose**: Improve documentation and tooling based on lessons learned from the development process, especially AI mistakes.\n * **Steps**:\n * After identifying a bug or execution failure, ask the AI what in its \"system prompt or tooling\" caused the mistake (46:38-46:47).\n * Update the AI's tooling, documentation, or system prompts based on this introspection to prevent future errors (46:49-46:53).\n * **Tools used**: `Claude Code` (or other primary AI agent).\n * **Tips/Gotchas**: This is a \"biggest hack for productivity\" and a \"biggest unlock\" for effective AI use (46:29, 47:19). It helps AI's responses \"get better\" over time (47:26-47:38).\n\n#### AI-Assisted Interview Preparation\n- **Purpose**: Prepare for job interviews using AI as a coach and for practice.\n- **Steps**:\n * Create a dedicated project (`Claude project`) to act as an interview \"coach\" (59:16-59:36).\n * Feed the project with \"all the best information out there\" on interview frameworks and tips (e.g., from Ben Arez's posts) (59:18-01:00:12).\n * Use the AI for mock interviews, asking it to provide feedback (01:00:16-01:02:05).\n * Use AI (e.g., `Perplexity's Comet browser`) to analyze online question banks (e.g., Lewis Lynn's) to prioritize common questions for mocks (01:01:28-01:01:51).\n * For questions without time to mock, ask `Claude` to \"play the candidate\" to learn from perfect answers (01:02:08-01:02:17).\n * Supplement AI mocks with human mock interviews, cold-outreaching to people on `LinkedIn` (01:00:21-01:00:37).\n * Build mini-apps (e.g., a quiz game in `Base 44`) to practice specific difficult concepts like segmentation (59:44-01:00:04).\n\n### 3. Tips, Techniques & Best Practices\n\n- **Graduate AI tools gradually**: For non-technical users, start with simple AI interfaces like `GPT projects` (beautiful UI, simple), then move to more advanced app builders like `Bolt` or `Lovable`, and finally to powerful IDEs like `Cursor` (12:57-13:17).\n- **Create an \"AI CTO\" project**: Establish a dedicated AI project (e.g., `GPT projects` or `Claude projects`) with an opinionated system prompt that tells the AI to act as a CTO. This AI should \"challenge\" the user, \"not be a people pleaser,\" and own the technical implementation, mitigating the \"sickopantic\" nature of general-purpose LLMs (09:53-10:25, 11:30-11:39).\n- **Make your codebase \"AI-native\"**: Add plain text and markdown files within the codebase that explain high-level structure and how agents should work in certain areas. This helps AI agents navigate and understand the codebase more easily (51:28-51:52). This is a task for technical people (51:34-51:35).\n- **Use multi-model reviews**: Employ different AI models (e.g., `Claude Code`, `Codeex`, `Composer`) to review the same code independently. Each model has distinct characteristics and will catch different issues, providing a more comprehensive review (00:45-00:51, 39:39-40:01, 43:39-44:35).\n- **Conduct AI post-mortems**: When AI makes a mistake or fails to execute correctly, ask the AI to introspect and identify what in its \"system prompt or tooling\" caused the error. Then, update the relevant documentation, tooling, or prompts to prevent the mistake from recurring. This is a \"biggest hack for productivity\" and crucial for improving AI performance over time (46:02-47:38).\n- **Leverage \"learning opportunity\" slash command**: When encountering difficult-to-understand technical concepts or code, use a slash command (e.g., `/learning-opportunity`) to prompt the AI to explain it using the 80/20 rule, tailored to a \"mid-level engineering knowledge\" persona (28:32-29:06, 45:22-45:29).\n- **Play to model strengths**: Understand the distinct \"personalities\" and capabilities of different AI models and use them accordingly (e.g., `Claude` for collaborative communication, `Codeex` for fixing worst bugs, `Gemini` for UI/design) (40:43-43:06).\n- **Own AI outputs**: Do not outsource thinking or blindly accept AI-generated content. Take responsibility for all outputs and ensure quality by guiding the AI with context (e.g., writing style, problem to solve) and reviewing its work (55:40-56:02, 57:13-57:52).\n- **For PMs in larger companies**: Focus on contained UI projects or creating PRs for developers to finalize, rather than heavy database changes or big projects (52:03-52:15).\n- **Be a 10x learner**: Especially for junior roles, prioritize learning and inquisitiveness. Don't rush into building. Use AI as a constant mentor and thought partner to accelerate learning and gain \"reps\" (01:00:41-01:00:55, 01:04:41-01:04:54, 01:06:06-01:06:08, 01:17:17-01:17:19).\n- **Don't fear AI replacement**: Focus on becoming better at using AI, as those who master AI will replace those who don't (00:52-00:58, 01:02:32-01:02:47).\n\n### 4. Metrics & Numbers\n\n- **Cost**: Speaker mentioned spending \"a couple bucks in AI credits\" per feature build (00:07:00-00:07:01).\n- **Efficiency**:\n * \"Full features take minutes\" to build with `Composer` (36:58-37:00).\n * Localizing `Studymate` from Hebrew to English took \"two days,\" which would \"probably take a dev team weeks\" (35:17-35:23).\n * Building a personal site from no domain to live on a domain took \"an hour and a half\" (35:25-35:31).\n * The thermal clothing business made \"$4 a sale\" initially, then \"100% profit\" after negotiating directly with the importer (01:11:42-01:12:38).","success":true}]} \ No newline at end of file diff --git a/ai_summary/r18_technical_perplexity.json b/ai_summary/r18_technical_perplexity.json new file mode 100644 index 0000000..9faba33 --- /dev/null +++ b/ai_summary/r18_technical_perplexity.json @@ -0,0 +1 @@ +{"success":true,"summaries":[{"provider":"perplexity","modelName":"Perplexity Sonar Online","summary":"### 1.

MCP for tool use like Linear integration; challenges thinking per `claude.md` system prompt; opinionated yet collaborative \"CTO\"\n- **Key features**: Analyzes codebase, asks clarifying questions; generates markdown plans with status trackers, TLDR, critical decisions\n- **Limitations**: Makes mistakes requiring post-mortems; not discussed further\n\n#### **Codeex** (OpenAI competitor to Claude Code)\n- **Category**: AI/ML — Coding interface\n- **Use case**: Code review in multi-model workflow; pasted results into Claude's `/peer-review`\n- **Key features**: Built-in code review; catches different bugs than Claude; \"best coder\" personality (hoodie/sandals, non-communicative but fixes worst bugs)\n- **Limitations**: Not discussed\n\n#### **Composer** (Cursor model)\n- **Category**: AI/ML — Fast execution model in Cursor\n- **Use case**: Executes plans quickly (e.g., full feature in minutes); used for non-complex tasks\n- **Key features**: \"Ridiculously fast\" and keeps flow; reviews code rapidly\n- **Limitations**: Not discussed\n\n#### **Gemini 3** (Google)\n- **Category**: AI/ML — Large Language Model\n- **Use case**: UI work; splits plans into backend/frontend, reads plan for frontend implementation; used in `anti-gravity` (Google's Cursor competitor)\n- **Key features**: \"Unbelievable at UI\"; artsy \"crazy scientist\" personality produces beautiful designs despite scary process (e.g., temporary deletes)\n- **Limitations**: Terrifying thought process (deletes dashboard, edits DB unnecessarily)\n\n#### **GPT Projects** (ChatGPT)\n- **Category**: AI/ML — Shared chat folders\n- **Use case**: Starting point for non-technical users; created \"CTO\" with custom prompt as technical owner; compartmentalizes contexts (e.g., running vs PM work); exposure therapy before `Cursor`\n- **Key features**: Custom instructions, shared knowledge base; memory feature (annoying for mixed contexts); voice mode for ideation like talking to CTO\n- **Limitations**: People-pleaser \"sycophantic\" behavior (hallucinated `Bun JavaScript` similarity to `Zustand`); mixes irrelevant memories\n\n#### **Linear** (Issue Tracker)\n- **Category**: DevOps — Project management\n- **Use case**: `/create-issue` generates formatted issues (TLDR, current state, expected outcomes, priority); exploration pulls from tickets (e.g., \"linear 88\")\n- **Key features**: MCP integration auto-creates issues; accessible for solo use\n- **Limitations**: Generated issues ready for exploration, not direct building; lower quality for team contexts\n\n#### **Studymate** (Custom App)\n- **Category**: Web App — Student study platform\n- **Use case**: Weekend side project making money; upload PDF, select pages/difficulty, generates quizzes via `Gemini` (currently multiple choice; demoed adding fill-in-blank drag-drop)\n- **Key features**: Sends user data + system prompt to `Gemini`; deep explanations/hints; Hebrew-to-English localization in 2 days\n- **Limitations**: Only multiple choice initially\n\n#### **Whisperflow** (Dictation)\n- **Category**: Productivity — Voice input\n- **Use case**: Dictating during live build demo (e.g., feature specs)\n- **Key features**: Not detailed\n- **Limitations**: Not discussed\n\n#### **MCP** (Anthropic)\n- **Category**: AI/ML — Tool integration\n- **Use case**: Enables Claude to use tools like Linear for issue creation\n- **Key features**: Gives AI tool-using ability\n- **Limitations**: Not discussed\n\n### 2. Workflows & Processes\n\n#### **Full Vibe Coding Workflow** (Non-technical app building in Cursor/Claude)\n1. **Mid-development idea capture**: `/create-issue` (quick questions, formats Linear ticket via MCP: TLDR, current state, outcomes, priority, e.g., STU88 for fill-in-blank)\n2. **Exploration phase**: `/exploration linear 88` (fetches ticket, analyzes codebase/files, asks clarifying questions on scope/data/UX/validation/grading/prompts; CTO-like)\n3. **Create plan**: `/create-plan` (markdown file from Twitter template: TLDR, critical decisions, concise steps with status trackers; reference for multi-model execution)\n4. **Execute plan**: Tag plan file in Cursor/Composer (\"execute @plan.md\"); fast code gen (full features in minutes)\n5. **Manual QA**: Run app locally, test changes\n6. **Self-review**: `/review` (Claude reviews own code: critical/high/medium bugs)\n7. **Multi-model peer review**: Run `/review` or equivalent in `Codeex`/Composer; paste results into Claude `/peer-review` (\"dev lead\" resolves/explains/fixes; models \"fight it out\")\n8. **Update docs**: `/update-docs` (post-mortem: ask what in prompt/tooling caused errors, iterate docs/system prompts/`claude.md` for future agents)\n- **Tools**: `Cursor`, `Claude Code`, `Linear`, `Composer`, `Codeex`, `Gemini 3`\n- **Tips/Gotchas**: Gradual adoption (GPT projects → Bolt/Lovable → Cursor light/dark mode); manual QA first; constant post-mortems prevent repeated bugs; use `/learning-opportunity` for 80/20 explanations\n\n#### **Graduation Workflow** (Tool progression for non-technical)\n1. GPT Projects (CTO custom prompt: owns tech, challenges ideas)\n2. Bolt/Lovable (eager coding)\n3. Cursor (full control, multi-model)\n- **Tools**: `GPT Projects`, `Bolt`, `Lovable`, `Cursor`\n- **Tips/Gotchas**: Exposure therapy for code fear; outgrow when needing control (e.g., payments)\n\n#### **Multi-Model Execution** (Leverage strengths)\n- Split plan backend/frontend; `Gemini 3` for UI, `Composer` for speed, Claude for planning\n- **Tools**: `Gemini 3`, `Composer`, `Claude Code`\n- **Tips/Gotchas**: Models have personalities (Claude=collaborative CTO, Codeex=bug fixer, Gemini=UI artist); peer review mitigates weaknesses\n\n### 3. Tips, Techniques & Best Practices\n- Create \"CTO\" in `GPT Projects` with custom prompt: \"Own tech decisions, challenge me, not a people pleaser\" to avoid sycophancy/hallucinations\n- Use slash commands for repeatable automation (e.g., `/learning-opportunity` primes for 80/20 explanations as \"technical PM in making\")\n- `/exploration`: Deeply understand problem/codebase before building; answer clarifying questions prepared\n- Plans as markdown: Portable for multi-model; track status for future agents\n- Post-mortems after every bug/failure: Ask AI \"what in your prompt/tooling caused this?\" then update docs/`claude.md`/slash commands\n- Make codebase \"AI-native\": Add markdown files explaining structure/areas for agents (technical setup needed)\n- For teams: PMs ship contained UI via PRs to devs; don't do heavy DB migrations\n- Reduce slop: Guide AI with context/style (like briefing junior); own outputs; Cursor `/ds-slop`\n- Interview prep: Claude project as coach (feed Ben Arez frameworks, Lewis Lynn question bank via `comet`); AI mocks + human mocks; AI as candidate for perfect answers; post-mock feedback\n- Start slow: GPT → app builders → `Cursor`; be inquisitive learner\n\n### 4. Metrics & Numbers\n- Full feature build (fill-in-blank): \"Few minutes\" with `Composer`; \"couple bucks in AI credits\"\n- Localization (Hebrew-English `Studymate`): 2 days (would take dev team weeks)\n- Personal site: Domain live in 1.5 hours\n- `Studymate` fill-in-blank: 30% of tests; 6 answers for 2 blanks (2 correct)","success":true}]} \ No newline at end of file diff --git a/docs/API.md b/docs/API.md new file mode 100644 index 0000000..875c15f --- /dev/null +++ b/docs/API.md @@ -0,0 +1,386 @@ +# API Reference + +Base URL: `/api` + +All endpoints accept and return JSON.

About This App

+

+ YouTube Podcast Transcript Processor extracts, processes, and summarizes transcripts from any YouTube video. Paste a URL, and the app fetches the full transcript using yt-dlp, then lets you clean it up with speaker detection, deduplication, and text normalization. +

+

+ Once processed, you can generate AI-powered summaries using Anthropic, Google Gemini, or Perplexity in three styles: bullet points with timestamp links, narrative essays, or structured technical extractions. Transcripts can be exported as TXT files, and AI summaries can be exported as PDF or TXT. +

+

+ The app also supports browsing entire channels and playlists, showing top videos ranked by views, and letting you jump between episodes with one click. +
