## What
The `description` field in `skills/stack-auth/SKILL.md` failed to parse
as YAML, surfacing on GitHub as:
> Error in user YAML: (<unknown>): mapping values are not allowed in
this context at line 2 column 338
## Why
The `description` was an **unquoted** YAML scalar containing a
colon-space sequence:
> …live, canonical instructions for every Stack Auth surface, including
the CLI**: **how to model users…
In YAML, `: ` inside an unquoted scalar is parsed as a key/value
mapping, which is illegal mid-value — hence *"mapping values are not
allowed in this context."*
## Fix
Wrapped the `description` value in **single** quotes. Single quotes (not
double) because the string already contains embedded double quotes
(`"stack auth"`, `"skill"`) but no apostrophes, so no escaping is
needed.
Verified the frontmatter now parses cleanly — all 9 keys (`name`,
`description`, `version`, `author`, `tags`, `testingTypes`,
`frameworks`, `languages`, `domains`) load via `yaml.safe_load`.
## Notes
- One-line change, content of the description is unchanged.
- The unrelated `@stackframe/dashboard` typecheck failure on this branch
comes from a stale generated `.next/dev/types/routes.d.ts` build
artifact and is not touched by this PR.

## Summary by cubic
Fixes YAML frontmatter parsing in skills/stack-auth/SKILL.md by quoting
the description, removing the “mapping values are not allowed in this
context” error. Wrapped the description in single quotes to prevent the
`CLI: how...` colon-space from being parsed as a mapping.

Rebased onto dev after PR 1475 (cl/hexclave-pr1) was squash-merged.
Squashes the original 46-commit branch (including PR1-duplicate commits
that arrived via cherry-picks/merges) into a single commit containing
only PR2's net delta over dev.

## Summary
- Adds a `hexclave` SKILL.md pointer skill that fetches the live skill
body on every invocation
- Adds an `/SKILL.md` route on the MCP app that renders the full skill
(CLI usage + docs sidebar generated from `docs.json`)
- Expands `docs-mintlify/guides/getting-started/ai-integration.mdx` with
three install paths (CLI, Skill, MCP) and per-agent config snippets
- Updates `packages/stack-shared/src/helpers/init-prompt.ts` to install
both the MCP server and skill file, with per-project vs global scope
detection
## Test plan
- [ ] `pnpm typecheck`
- [ ] `pnpm lint`
- [ ] Hit the MCP app's `/SKILL.md` endpoint locally and verify it
returns valid markdown with the full docs sidebar
- [ ] Render the updated `ai-integration.mdx` in Mintlify preview and
confirm tabs/cards render

## Summary by CodeRabbit
* **Documentation**
* Rewrote the AI integration guide with complete, user-facing
instructions for connecting Stack Auth to coding agents; removed the
separate MCP setup page and updated site navigation.
* Added the canonical Stack Auth skill content and guidance that clients
should fetch the latest skill at runtime.
* **New Features**
* MCP now serves the canonical Stack Auth skill dynamically and provides
interactive skill responses.
* Init prompts now include full MCP + skill install workflows and scope
guidance.
* Added a health-check endpoint.
* **Chores**
* Added scaffold and configs for a new skills app (build, dev, lint, and
type settings).
