Changelog

v1.0.0 (2026-06-06)

Phase 5: Polish & Release

E9: Developer Experience

  • CLI Runner (src/cli.ts): Standalone CLI for ingest, search, memory, stats, kb operations. Run with bun run src/cli.ts <command> [args]. Uses the same function calls as the plugin.
  • Configuration System (src/config.ts): Structured config from env vars (BRAIN_HOME, BRAIN_AUTO_INGEST, BRAIN_DEBUG, BRAIN_MAX_FILE_SIZE_MB, BRAIN_CHUNK_MAX_TOKENS) with validation and defaults. Singleton getConfig() export.
  • Updated documentation: HISTORY.md and README.md now accurately reflect all tools and architecture.

E10: Release

  • Token Budget Audit: Measured all 10 tool descriptions + system prompt = ~262 tokens (well under 400 budget). No trimming needed.
  • Error Message Quality: All tool handlers now have catch blocks producing actionable JSON error messages (not raw stack traces). kbRecord improved error messages with context.
  • Version 1.0.0: Final build. All 247 tests passing.

v0.3.5 (2026-06-06)

Phase 4: Search & Discovery

E7: Search Enhancement

  • FTS5 Hybrid Search (src/search/unified.ts): Weighted RRF fusion with FTS5 + vec0 vector search. Configurable weights based on embedding availability (real vs. pseudo-embeddings).
  • Query Parser (src/search/queryParser.ts): Structured filter parsing from query strings (language:ts path:src/). Validated filter keys and values, rejecting unknown keys.
  • FTS5 Sanitizer (src/search/ftsSanitizer.ts): Safe query sanitization for FTS5 MATCH, stripping reserved words and special characters.
  • Symbol Search (src/search/unified.ts): FTS5 search on global symbol store. Search by name, qualified_name, kind, project.
  • FTS5 content-sync triggers: All three content types (documents, memories, knowledge entries) auto-sync to FTS5 virtual tables on INSERT/UPDATE/DELETE.

E8: Knowledge Store

  • Confidence Auto-Bump: Fixed outcomes auto-bump confidence by +0.1 (capped at 0.9). 5+ fixed outcomes auto-promote to "accepted".
  • Occurrence Tracking (knowledge_occurrences table): Record outcomes (fixed, failed, workaround, observed) with project/repo/issue/commit references.
  • Revision History (knowledge_revisions table): Track all field changes with confidence and review state at time of change.
  • REGATE Lifecycle (src/knowledge/store.ts): Validated state machine for draft→reviewed→accepted→rejected with terminal state enforcement.
  • Separate tool per KB operation: brain_kb_get, brain_kb_add, brain_kb_record, brain_kb_review, brain_kb_search, brain_kb_stats.

v0.2.4 (2026-06-06)

  • Moved personal dev references to AGENTS.local.md
  • Replaced vec0 compilation with prebuilt binary download from GitHub Releases

v0.2.3 (2026-06-05)

  • Auto-capture hooks trigger on session idle
  • /brain slash commands (ingest, search, reindex, memory, kb-*)

v0.2.2 (2026-06-05)

  • Knowledge store with confidence gating
  • REGATE review lifecycle

v0.2.1 (2026-06-05)

  • Per-session LRU cache (embeddings, search, chunks, hashes)
  • Content-hash dedup in ingest pipeline

v0.2.0 (2026-06-05)

  • Unified brain: three engines (search, memory, knowledge)
  • FTS5 full-text search integration

v0.1.0 (2026-06-05)

  • Initial plugin skeleton
  • SQLite schema and basic engine structure
