Expand the local RAG system from code-only indexing into a full knowledge base with four sources: site code, database schema, WordPress API signatures, and bundled reference docs. The ReAct agent automatically consults the knowledge base before reasoning. New PHP abilities: - schema-extract: SHOW TABLES + DESCRIBE with semantic context for core WP tables and sensitive column redaction - wp-api-extract: scans wp-includes/ for function signatures and docblocks, groups ~5 per chunk - docs-extract: reads curated markdown from docs/knowledge/, chunks by heading boundaries New knowledge base docs (docs/knowledge/): - database-schema, hooks-lifecycle, options-api, post-types, user-roles, rest-api, cron, queries, security, theme-development, plugin-development, performance, multisite Settings UI (Knowledge Base card): - Build/Rebuild Index button with progress bar - Status display: last built, chunk counts by source - Clear Index button - Indexing service extracted into knowledge-base.js Auto-consult (react-agent.js): - Before ReAct loop, initializes vector store from IndexedDB - Searches top-2 results matching user message - Injects as [Relevant knowledge base context] prefix (~1750 chars) - Best-effort: failures do not block the agent Code search broadened: - Label: "Search knowledge base" (was "Search site codebase") - Keywords: added database, schema, wordpress, documentation Bugfix: codebase-extract.php used undefined register_agentic_ability() - Fixed to wp_agentic_admin_register_ability() and added missing registration in class-abilities.php.

Auto-consult only injects RAG context when user enables the library icon toggle in the chat input (next to web search globe). Saves ~500 tokens on every message when knowledge base is not needed. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

There was a problem hiding this comment.
4-source knowledge base with auto-consult gated behind a library icon toggle (same pattern as web search globe). RAG context only injected when the user opts in — saves ~500 tokens per message otherwise. Settings UI with build/clear index. LGTM!
