Documentation Updates - 2026-02-23

This PR updates the documentation based on features merged in the last 24 hours.

Features Documented

• private: true frontmatter field that blocks gh aw add from installing workflows into other repositories (from Add private frontmatter field to block add command #17801)

Changes Made

• Updated docs/src/content/docs/reference/frontmatter.md to add a new Private Workflows (private:) section documenting the new field, its behavior, and a clarifying note that it only restricts gh aw add (not repository visibility)
• Updated docs/src/content/docs/guides/packaging-imports.md to add a note in the "Adding Workflows" section, warning users that workflows marked private: true cannot be added from external repositories

Merged PRs Referenced

• Add private frontmatter field to block add command #17801 — Add private frontmatter field to block add command
• 🔔 Add CI trigger token support for PR and branch pushes #17803 — Add CI trigger token support for PR and branch pushes (already included own docs updates in the PR)
• [q] fix: disable Chromium sandbox in Playwright MCP to allow localhost access #17808 — Fix: disable Chromium sandbox in Playwright MCP (internal fix, no doc changes needed)

Notes

PR #17803 (CI trigger token) already included its own documentation updates to auth.mdx, faq.md, and safe-outputs.md. PR #17801 regenerated frontmatter-full.md but left the main human-readable frontmatter.md without the new private: field — this PR fills that gap.

For consistency with other boolean fields like strict: (line 354), consider mentioning the default value. The field defaults to false, meaning workflows are not private unless explicitly marked. This could be added to line 59, for example: "Mark a workflow as private to prevent it from being installed into other repositories via gh aw add. Defaults to false."

Suggested change

	Mark a workflow as private to prevent it from being installed into other repositories via `gh aw add`.
	Mark a workflow as private to prevent it from being installed into other repositories via `gh aw add`. Defaults to `false`.
