Summary

Major upgrade across all 3 packages delivering 5 phases of improvements identified by a comprehensive 7-agent audit (architecture, performance, security, code quality, test coverage, competitive landscape, DX/UX).

Root cause addressed: sql.js (in-memory, full-file serialize) was responsible for 70% of all issues — replaced with better-sqlite3 behind a clean adapter interface.

Changes

Phase 1 — SQLite Adapter Pattern

  • DatabaseAdapter interface with BetterSqliteAdapter (WAL mode, concurrent access) and SqlJsAdapter (debounced persist fallback)
  • Factory auto-detects native module availability at runtime
  • N+1 query eliminated in EntryStore.index() (4,856 statements → 1 batch query)
  • Tag map caching with invalidation (no more full table scan per search)
  • All per-mutation persist() calls removed (WAL handles durability)

Phase 2 — Security Hardening + Performance

  • 3 medium-severity vulnerabilities fixed:
    • Hook parser: safePath() containment validation before reading scripts
    • Watcher: followSymlinks: false + realpath() resolution
    • Webview: openFile path validation against allowedRoots
  • SSRF: redirect: 'error' on importFromUrl fetch
  • Dependency vulnerabilities patched (ws, fast-uri, brace-expansion → 0 vulns)
  • Fuse.js content truncated to 500 chars (memory 10.8MB → ~2MB)
  • Shared filter-utils.ts extracted (DRY across engines)
  • Deterministic entry ordering after parallel parse
  • Event emission eliminated on initial scan (1,214 → 0)
  • CLI lazy-imports interactive command (defer Ink/React)
  • Typed event listener map with handler isolation

Phase 3 — Test Coverage (+150 tests)

  • sync.test.ts — 32 tests (export/import, SSRF blocking, URL fetch)
  • multi-agent-parser.test.ts — 14 tests (Cursor, Copilot, Windsurf, Aider)
  • watcher.test.ts — 14 tests (events, debounce, symlink config)
  • search-engine.test.ts — 18 tests (tier routing, LRU cache, TTL)
  • error-paths.test.ts — 16 tests (corrupt DB, malformed YAML, ENOENT)
  • query-parser.test.ts — 19 tests (all operators, edge cases)
  • CLI commands: 37 tests (list, search, stats, doctor, tag, favorite)
  • Coverage threshold configured: 80% lines, 75% functions, 70% branches

Phase 4 — DX/UX Improvements

  • QueryParser: fzf-style operators ('exact ^prefix !exclude tag:x type:skill source:y)
  • First-run onboarding with guided next steps
  • --tag filter on CLI search (parity with VS Code)
  • Grouped help output (Discovery, Management, Data, Setup)
  • Bulk favorite/tag with --type filter
  • Config: JSON array parsing + tilde expansion
  • --tui / --no-tui flags (explicit mode control)
  • VS Code: filter-by-type toolbar button
  • VS Code: search syntax help in QuickPick

Phase 5 — Competitive Features

  • FTS5 full-text search (migration v3): standalone virtual table, MATCH queries with bm25 ranking, prefix matching, graceful LIKE fallback
  • Column indexes on type, source, favorite
  • Staleness detector: flags entries >30 days stale or with missing source files
  • Quality scorer: 0-100 across recency, usage, completeness, engagement
  • vault audit command: combined staleness + quality report
  • Remote registry protocol: RegistryManager + JsonRegistryAdapter with 5min TTL cache
  • vault registry add/remove/list/search commands

Cleanup

  • Removed dead sqlite-connection.ts and migrations.ts (superseded by adapter pattern)
  • Updated AGENTS.md with commitlint scopes, PR template reference, path-router docs

Validation Sign-Off

Validator Verdict
Build & Type Safety GO — 0 errors, 409/409 tests, VSIX packages

Test Plan

  • pnpm typecheck — 0 errors across all packages
  • pnpm test — 409/409 passing
  • pnpm build — all packages build successfully
  • pnpm format:check — all files formatted
  • pnpm audit — 0 vulnerabilities
  • VS Code extension packages as VSIX (598 KB)
  • Manual: verify vault search returns results with new FTS5 tier
  • Manual: verify vault audit produces staleness/quality report
  • Manual: verify VS Code filter-by-type toolbar button works
  • Manual: verify concurrent CLI + VS Code access doesn't corrupt data

Uses createRequire to import package.json at runtime so the CLI
version stays in sync with package.json automatically — no manual
updates needed when bumping versions.
Unifies all package versions at 0.1.7 for the first coordinated
release. Updates release-please manifest to match.
Introduces a DatabaseAdapter interface with two implementations:
- BetterSqliteAdapter: native SQLite with WAL mode, busy_timeout,
  and file-level locking for safe concurrent access
- SqlJsAdapter: fallback with 2s debounced persist for environments
  without native modules

Key improvements:
- Eliminates 15.4MB full-DB serialize on every mutation (WAL handles durability)
- Fixes N+1 query in EntryStore.index() (batch SELECT before loop)
- Adds tag map caching with invalidation (no more full scan per search)
- Removes all manual persist() calls from stores
- Factory auto-detects better-sqlite3 availability, falls back to sql.js

Projected: memory 335MB→80MB, cold start 859ms→300ms, bundle 1.49MB→200KB
- Hook parser: validate script paths with safePath() before reading,
  restricting to claudeConfigPath and CWD (prevents arbitrary file read
  via malicious .claude/settings.json)
- Watcher: add followSymlinks: false to chokidar options (prevents
  symlink-based file exposure in ~/.claude/)
- Webview: validate openFile paths against allowedRoots before opening
  (prevents arbitrary file access from webview messages)
- Sync: add redirect: 'error' to importFromUrl fetch (SSRF hardening)
- Deps: add pnpm overrides to patch ws, fast-uri, brace-expansion

Also adds safePath() and isSecretFile() utilities to parsers/utils.ts
…dering

- Fuse.js: truncate content to 500 chars on index (memory 10.8MB→~2MB)
- Extract shared applyFilters() into filter-utils.ts (DRY across engines)
- Skip per-entry events on initial scan (1,214 events→0)
- Sort entries by stable ID after scan (deterministic cross-run ordering)
- CLI: lazy-import interactive command (defer Ink/React until needed)
- Typed event listener map with handler isolation (try-catch in emit)
New test files:
- sync.test.ts: 32 tests (export/import roundtrip, SSRF blocking, URL fetch)
- multi-agent-parser.test.ts: 14 tests (Cursor, Copilot, Windsurf, Aider)
- watcher.test.ts: 14 tests (events, debounce, symlink config, lifecycle)
- search-engine.test.ts: 18 tests (tier routing, LRU cache, TTL, suggest)
- error-paths.test.ts: 16 tests (corrupt DB, malformed YAML, ENOENT)
- query-parser.test.ts: 19 tests (all operators, edge cases)
- CLI commands: 37 tests (list, search, stats, doctor, tag, favorite)

Also adds coverage thresholds (80% lines, 75% functions, 70% branches)
to vitest.config.ts as a CI gate.

Total: 259→409 tests (58% increase)
QueryParser adds fzf-style search operators across all tiers:
  'exact  ^prefix  !exclude  tag:name  type:skill  source:gstack

CLI enhancements:
- First-run onboarding with guided next steps after vault init
- --tag filter on search command (parity with VS Code)
- Grouped help output (Discovery, Management, Data, Setup)
- Bulk favorite/tag operations with --type filter
- Config: handle JSON arrays and tilde expansion
- Explicit --tui / --no-tui flags (removes magic TTY switching)

VS Code extension:
- Filter-by-type button in tree view toolbar
- Search syntax help displayed in QuickPick results
…gistry

FTS5 full-text search (migration v3):
- Standalone FTS5 virtual table rebuilt after each index()
- MATCH queries with prefix matching and bm25 ranking
- Graceful fallback to LIKE if FTS5 unavailable
- Column indexes on type, source, favorite for filter queries

Staleness detection:
- detectStaleness() checks source file mtime vs entry lastModified
- Flags entries >30 days stale or with missing source files
- Batched parallel stat() with concurrency limit of 50

Quality scoring:
- scoreEntries() rates 0-100 across recency, usage, completeness, engagement
- Surfaces low-quality entries (no description, no tags, never used)

Remote registry:
- RegistryManager aggregates multiple RegistryAdapter instances
- JsonRegistryAdapter fetches static JSON registries with 5min TTL cache
- vault registry add/remove/list/search commands

CLI:
- vault audit: staleness + quality report with --json, --threshold, --min-score
- vault registry: manage and search remote skill registries
These files are superseded by the DatabaseAdapter pattern:
- sqlite-connection.ts → replaced by better-sqlite-adapter.ts + sqljs-adapter.ts
- migrations.ts → inlined into sqlite-engine.ts runAdapterMigrations()

No active imports reference either file. Also updates AGENTS.md with
commitlint scopes, PR template reference, and path-router documentation.
