Complete rewrite of the OpenClaw plugin to run entirely in-process without requiring the Python proxy server. Users just install and go: openclaw plugins install @contextpilot/openclaw-plugin Engine modules ported from Python to TypeScript: - engine/extract.ts: Document extraction from system/tool_results (XML tags, numbered lists, JSON results, markdown headers, separators) for both OpenAI Chat and Anthropic Messages API formats (1042→969 lines) - engine/dedup.ts: Cross-turn block-level deduplication using content-defined chunking + SHA-256 hashing (250→355 lines) - engine/cache-control.ts: Anthropic cache_control injection for system messages and tool_result content blocks (144 lines) - engine/reorder.ts: Simplified LCP-based document reordering that maximizes prefix cache sharing across turns — no numpy/scipy needed Plugin integration: - Uses OpenClaw's wrapStreamFn to intercept requests before they reach the LLM backend, apply all optimizations, then forward - Registers contextpilot provider with dynamic model resolution - contextpilot_status tool reports engine state and savings
Tests cover all four engine modules: - extract (18 tests): XML/numbered/JSON extraction, OpenAI/Anthropic format handlers, system+tool_result extraction, reconstruction - dedup (7 tests): content-defined chunking, block hashing, cross-message deduplication for chat+responses API formats - cache-control (6 tests): Anthropic cache_control injection for system/tool_results, immutability, OpenAI no-op, dispatcher - reorder (7 tests): deterministic hash sort, cross-turn prefix stability, reset behavior, index mapping correctness All 38 tests pass in 18ms.
…sts) Tests simulate the exact wrapStreamFn pipeline end-to-end: - Anthropic: system XML extraction+reorder+cache_control, tool_result cache injection, scope=system/tool_results filtering - OpenAI: system reorder, duplicate tool result dedup with reference hints, responses API dedup, passthrough for plain messages - Multi-turn: ReorderState preserves doc order across turns, reset clears history - Edge cases: empty body, no messages, single doc (no reorder), short content (no dedup), null messages, system as block array Total test suite: 54 tests (38 unit + 16 integration), all pass in 165ms.
Full port of all Python ContextPilot modules to zero-dependency TypeScript: Core index (replaces numpy+scipy): - tree-nodes.ts: ClusterNode + NodeManager (334 lines) - compute-distance.ts: O(n) merge-based distance computation (224 lines) - index-construction.ts: hierarchical clustering with pure-TS linkage() (348 lines) - intra-ordering.ts: within-context reordering via tree prefix (349 lines) - inter-scheduler.ts: cross-context scheduling via path grouping (116 lines) Live engine: - live-index.ts: ContextPilot class — search/insert/evict/reorder (1232 lines) - metadata.ts: NodeMetadata for per-node runtime tracking (82 lines) - eviction-heap.ts: LRU min-heap for SGLang cache eviction sync (317 lines) - conversation-tracker.ts: multi-turn document deduplication (241 lines) - http-client.ts: native fetch() client for index server comms (267 lines) Previously ported: - extract.ts: document extraction from system/tool_results (969 lines) - dedup.ts: cross-turn block-level content dedup (355 lines) - cache-control.ts: Anthropic cache_control injection (144 lines) - reorder.ts: simplified LCP reorder fallback (109 lines)
index.ts now supports three backend modes: - anthropic: in-process ContextPilot engine (clustering + reorder + dedup + cache_control) - openai: in-process engine (same pipeline, OpenAI cache is automatic) - sglang: remote ContextPilotIndexClient → index server for cache-aware reorder, in-process dedup, no cache_control injection (RadixAttention handles caching) Config additions: - backendProvider now accepts 'sglang' - indexServerUrl: URL for ContextPilot index server (default: http://localhost:8765) contextpilot_status tool shows engine stats (cloud) or server health (sglang)
