v0.3.2

Bug Fixes

• Per-association error resilience — A single broken association (e.g. missing target class) no longer aborts the entire model. Warnings are collected and surfaced in the extraction summary. (#24)
• Dynamic concern directory discovery — ConcernExtractor now globs app/**/concerns/ to find all concern directories, including deeply nested ones. (#25)
• JsonSnapshotStore fallback — On MySQL-only hosts where sqlite3 isn't in the Gemfile, temporal snapshots now fall back to JSON files instead of silently failing.
• MCP parameter type coercion — String values from MCP clients are now coerced to integers where expected, preventing handler crashes.
• extend dependency tracking — extended modules are now tracked as dependencies in model and concern extractors (previously only include was detected).
• Array-form WHERE support — EmbeddedExecutor now handles array-form WHERE clauses for JSON column queries.
• Configurable embedded sql/query tools — Read-only sql/query tools in embedded mode are now opt-in via read_tools_enabled, with SqlValidator + SafeContext defense-in-depth.
• Notion sync columns metadata — ModelExtractor now writes rich columns metadata (name/type/null/default) so Notion::Exporter#sync_model_columns actually has data to sync.

v0.1.0 — Initial Release

CodebaseIndex v0.1.0

Rails codebase extraction and indexing for AI-assisted development. Uses runtime introspection to produce version-accurate representations with inlined concerns, resolved callback chains, and schema-aware associations.

Highlights

• 34 extractors covering models, controllers, services, jobs, mailers, routes, middleware, GraphQL, Pundit, state machines, events, caching, factories, and more
• 2 MCP servers — 27-tool index server (reads pre-extracted JSON) + 31-tool console server (bridges to live Rails)
• Full retrieval pipeline — query classification, hybrid search, RRF ranking, token-budgeted context assembly
• Backend agnostic — pgvector, Qdrant, or SQLite for vectors; MySQL or PostgreSQL for metadata; OpenAI or Ollama for embeddings
• Behavioral depth — callback side-effect analysis, resolved Rails config introspection, optional pre-computed request flow maps
• Notion export — sync extraction data to Notion databases
