From 82fd221ae3ada8d198f6dd740e775c3d2b27bdc1 Mon Sep 17 00:00:00 2001 From: bordumb Date: Mon, 2 Feb 2026 22:51:05 +0000 Subject: [PATCH 01/16] feat(fn-56.7): add unified tool registry for Dataing Assistant Introduces a central registry for organizing assistant tools by category with per-tenant enable/disable configuration. - ToolCategory enum: FILES, GIT, DOCKER, LOGS, DATASOURCE, ENVIRONMENT - ToolConfig dataclass for tool metadata and priority - TenantToolConfig for tenant-specific tool overrides - ToolRegistry class with singleton pattern -

debugging infrastructure issues, understanding data quality problems, querying connected datasources, and getting context on investigations. Currently they must use external tools or ask for human help. + +**Solution**: Persistent chat widget ("Dataing Assistant") that provides a unified AI assistant with access to: +- Local files, configs, and git history +- Docker container status and logs +- Connected datasources (reusing existing query tools) +- Investigation context and findings +- User's recent activity for contextual suggestions + +## Key Decisions (from interview) + +### Agent Configuration +- **LLM Model**: Claude Sonnet (fast, cost-effective) +- **Response time target**: First token under 3 seconds +- **Agent focus**: Balanced - explain root cause AND provide fix steps with code snippets +- **Out-of-scope handling**: Polite decline, redirect to docs +- **Tone**: Match existing Dataing UI voice + +### Tools & Capabilities (Priority Order) + +1. **File Access** + - Read any UTF-8 text file in allowlisted directories + - Smart chunking: request specific line ranges + - Grep-like search across files (max 100 results) + - Include logs, data samples (CSV/parquet first N rows) + - Centralized parsers in `core/parsing/` organized by file type + +2. **Git Access** + - Full read access via githunter tools + - blame_line, find_pr_discussion, get_file_experts + - Recent commits, branches, diffs + +3. **Docker Access** + - Container status via Docker API + - Log reading via pluggable LogProvider interface + - Auth: Configurable per deployment (socket, TCP+TLS, env auto-detect) + +4. **Log Providers** (pluggable interface) + - LocalFileLogProvider + - DockerLogProvider + - CloudWatchLogProvider (IAM role auth) + +5. **Datasource Access** + - Reuse existing query tools from investigation agents + - Full read access to connected datasources + - Unified tool registry for all capabilities + +6. **Environment Access** + - Read non-sensitive env vars (filter *SECRET*, *KEY*, *PASSWORD*, *TOKEN*) + - Compare current config with .env.example defaults + +### Security + +- **Path canonicalization** before allowlist check (prevent traversal) +- **Blocked patterns**: `.env`, `*.pem`, `*.key`, `*secret*`, `*credential*` +- **Security-blocked errors**: Suggest alternatives ("Can't

indicators**: Show detailed progress ("Reading docker-compose.yml...") + +### Data Model + +**Debug chats are investigations** with parent/child relationships: +- Each chat session gets its own `investigation_id` +- Can be linked to existing investigations as parent OR child +- Child chats have full access to parent investigation context +- DebugChatSession model with FK to Investigation

+- **Panel width**: Resizable, remembers size per-user preference +- **Keyboard shortcut**: None for MVP +- **Markdown**: Full rendering (headers, lists, code blocks, links, tables) + +**Chat behavior**: +- Smart placeholder text with example questions +- Permanent history with session list (new sessions start fresh, can reopen old) +- Minimize to button (badge shows unread), preserves state +- Collapsible sections for long responses +- Copy code button always visible on code blocks +- Edit and resubmit previous messages + +**Streaming & errors**: +- Queue messages if user sends while response streaming +- Auto-retry 3x on errors before showing error +- Offline: Retry with exponential backoff + "Reconnecting..." indicator + +### Concurrency & Limits + +- **Message queueing**: Complete current response, then process next +- **Context limit**: Token-based, summarize when approaching model limit +- **Rate limiting**: Admin-set token budget per tenant +- **Limit exceeded**: Soft block with override for urgent issues +- **Usage display**: Always visible ("X of Y tokens used this month") + +### Context & Memory + +- **User context**: Full access to recent investigations, alerts, queries +- **Memory integration**: User confirms "This was helpful" to save to agent memory (fn-55) +- **Multi-tenancy**: Tenant isolation - each tenant gets isolated agent instance + +### Export + +- **Formats**: Both JSON and Markdown export +- **Sharing**: No sharing for MVP (export and send manually) + +### Testing & Telemetry + +- **Testing**: Unit tests with mocked LLM +- **Dry run**: No special mode, use real APIs in test environment +- **Telemetry**: Full integration with existing Dataing telemetry +- **Metrics**: Defer to later (analyze datasets first) +- **Analytics**:

add centralized file parsers (core/parsing/) Introduces unified parsing utilities for the Dataing Assistant: - TextParser: UTF-8 text files with line-range chunking and search - YamlParser: Safe YAML loading with format_summary for LLMs - JsonParser: JSON parsing with schema inference and summaries - LogParser: Log files with level detection, timestamps, JSON support - DataParser: CSV/Parquet sampling without full memory load All parsers include: - Size limits to prevent resource exhaustion - Consistent error handling - Helpful summaries for LLM consumption 58 unit tests covering all parsers.

17 00:00:00 2001 From: bordumb Date: Mon, 2 Feb 2026 23:02:00 +0000 Subject: [PATCH 03/16] feat(fn-56.2): add local file reader tool with safety features Implements safe file access for the Dataing Assistant with: - Directory allowlist: python-packages/, frontend/, demo/, docs/ - Root file patterns: docker-compose*.yml, *.md, pyproject.toml, etc. - Blocked patterns: .env, *.pem, *.key, *secret*, *credential* - Path traversal prevention via canonicalization - Symlink target validation - File size limit (100KB) - Line-range reading support - File search across repository - Directory listing Includes LocalFileReader class and tool functions: - read_local_file - Read file with safety checks - search_in_files - Search pattern across files - list_directory - List files in directory 27 unit tests covering security requirements.

provider interface with local, docker, cloudwatch implementations - Add LogProvider protocol and BaseLogProvider ABC with search_logs - Add LocalFileLogProvider with pattern filtering, pagination, truncation - Add DockerLogProvider for container logs with status checks - Add CloudWatchLogProvider (optional, requires boto3) - Fix pattern filter to check both message and raw line - Fix truncation logic to track last processed line correctly - Add _matches_pattern helper for consistent search behavior - Add unit tests for base types and local provider (24 tests) Co-Authored-By: Claude Opus 4.5

Created migration 035_dataing_assistant.sql with three tables: 1. assistant_sessions - Links sessions to investigations (each session is an investigation) - Parent/child investigation linking support - Token usage and last_activity tracking - User preferences in metadata JSONB 2. assistant_messages - Chat messages with role (user/assistant/system/tool) - Tool call tracking as JSONB array - Per-message token count 3. assistant_audit_log - Security audit trail of all tool usage - Action type, target, result summary - Full metadata in JSONB Includes indexes for fast queries and trigger to auto-update session activity.
