External skills (manual install)¶

Status enum (single source of truth across the catalog)

Every external-skill or MCP entry below carries a status: value:

Status	Meaning	Where it links
`vendored`	Already in `vendor.yaml`.	Link to the `skills/vendor/<name>/` (or series) entry.
`deferred`	Open `TODO P?` item — under consideration.	Link to the `TODO.md` anchor.
`skipped`	Looked at, chose not to vendor.	Inline reason required (1 sentence).
`evaluated`	Read but no decision recorded. Effectively "tracked."	Inline 1-line note describing what was learned.
`wishlist`	Surfaced but not yet evaluated.	No link required; default for fresh discoveries.

Status changes are explicit edits — see the Adding catalog entries workflow doc (under Workflows in the nav) for the wishlist → deferred → vendored recipe.

Manual install for non-vendored skills

When a skill is not in vendor.yaml, you can still install it directly from upstream via the npx skills CLI:

# Whole-repo install (if SKILL.md sits at repo root or skills/)
npx skills@latest add <owner>/<repo>

# Subpath install (when the skill is nested)
npx skills@latest add <owner>/<repo>/<path-to-skill-dir>

# Cherry-pick by name
npx skills@latest add <owner>/<repo> -s <skill-name>

# Force deep discovery (skill nested >1 level inside skills/)
npx skills@latest add <owner>/<repo> --full-depth -s <skill-name>

For Anthropic-style plugin marketplaces (e.g. anthropics/financial-services, anthropics/knowledge-work-plugins), use the Claude Code plugin commands instead:

claude plugin marketplace add <owner>/<repo>
claude plugin install <plugin-name>@<repo-name>

For MCP servers, see the per-entry "Auth & install" section in the MCP wiki — install commands vary by transport (HTTP / stdio / SSE) and host (Claude Code / Claude Desktop / Cursor / Managed Agents).

Skill / Plugin	Upstream	Status	Why this status	Install hint
`tampermonkey`	henkisdabro/wookstar-claude-plugins	`skipped`	API-focused; the owned skill captures our lifecycle/native-testing workflow. Review.	`npx skills@1.5.25 add henkisdabro/wookstar-claude-plugins --skill tampermonkey`
`develop-userscripts`	xixu-me directory listing	`evaluated`	Listing reviewed; upstream API returned 404 on 2026-09-09.	Source/installability unverified
`userscript-creator`	andradeatdev directory listing	`wishlist`	Search result only; upstream API returned 404 on 2026-09-09.	Source/installability unverified
Other `vercel/vercel-plugin` skills	`vercel/vercel-plugin`	`evaluated`	We already vendored 4 of them into `fullstack-nextjs`. Remaining ones (e.g. `tailwind`, `vercel-ai-sdk`, etc.) are candidates if needed.	`npx skills@latest add vercel/vercel-plugin -s <skill>`
Remaining `vercel-labs/agent-skills`	`vercel-labs/agent-skills`	`evaluated`	We vendored `web-design-guidelines`. Others are similar audit-style skills.	`npx skills@latest add vercel-labs/agent-skills -s <skill>`
Other `warpdotdev/oz-skills` (9 skipped)	`warpdotdev/oz-skills`	`skipped`	Skipped per `docs/reference/warp-oz-skills.md`: `mcp-builder` (duplicate), `webapp-testing` (duplicate), `scheduler` (too narrow), Slack-/BigQuery-specific ones.	(not vendored)

MCP servers¶

Name	Upstream	Status	Auth	Records
`chrome-devtools`	`@modelcontextprotocol/server-chrome-devtools`	`evaluated`	Local stdio	no per-MCP record yet — required by `web-performance-audit`

Backlog (TODO `P?` items)¶

See the P? lane in TODO.md:

[?/M] Playwright skill — web automation, testing, and website-cloning workflows realistic for agents to maintain.
[?/L] Sibling docs-stack skills (docusaurus / vitepress / hugo / sphinx) — paired with the existing mkdocs-site-bootstrap skill.
