+### Docs
+- SEO fixes on the docs landing page (`docs/introduction.mdx`): replace the duplicate-brand title `Failproof AI` (which Mintlify rendered as `Failproof AI - FailproofAI`) with the keyword-bearing `Introduction — Failure Handling for AI Agents`, rewrite the 84-char generic meta description into a ~150-char one naming the 39 built-in policies + key failure modes (loops, secret leaks, destructive tool calls), seed the page body with the missing search keywords (`AI failure handling`, `error recovery`, `LLM reliability`) by reframing the lede, expand the CLI list to the actual 7-CLI surface, and correct the stale `26 built-in policies` card to the current `39`. Also corrects the same stale `26` count in `docs/architecture.mdx`'s Builtin policies section.
+
 ### Fixes
 - Dashboard `/policies` activity-tab subheading: replace the hardcoded "Policy evaluations for Claude" with a dynamic list of installed CLIs ("Policy evaluations across Claude Code, Cursor"), collapsing to "across N agents" when 4 or more are installed and falling back to "Policy evaluations" when none are. Reads from the existing `getHooksConfigAction()` payload — no new server work. The text was a leftover from when failproofai only supported Claude Code and was inaccurate against the now-7-CLI surface (Claude, Codex, Copilot, Cursor, OpenCode, Pi, Gemini) (#358).
