Sync docs

Regenerate the public skill catalog from skills/*/SKILL.md. One source of truth for the README catalog, the CLAUDE.md catalog, and the per-skill pages on the docs site.

Input

$ARGUMENTS — empty for write mode (default), or --check for drift detection.

/sync-docs
/sync-docs --check

Phases

The skill runs through 5 phases. No user interaction.

Phase 1 — Preflight

Verify the working tree is the yoke plugin repo:

test -f .claude-plugin/plugin.json && test -d skills/

Parse --check from $ARGUMENTS. Set MODE=check when present, MODE=write otherwise.

Create the tmp tree:

rm -rf .yoke/sync-docs-tmp && mkdir -p .yoke/sync-docs-tmp/skills

Phase 2 — Enumerate

List the shipped skills:

ls -d skills/*/ | xargs -n1 basename

Include every directory under skills/ that contains a SKILL.md. Never include anything under .claude/skills/ — yoke-create, yoke-release, and yoke-validate are local-only tools and must not appear in the public catalog.

The shipped catalog today is 15 skills: bootstrap, do, draft, gca, gp, grill, grill-docs, handoff, help, issues, journal, merge, pr, prd, review.

Phase 3 — Render

For each enumerated skill:

1. Read skills/<name>/SKILL.md. Parse the YAML frontmatter into name and description.
2. Extract trigger phrases — every quoted substring inside description that begins with a lowercase letter or a forward slash (e.g. "sync docs", "--check").
3. Read docs/<name>.md when present; otherwise extract ## Input, ## Output, and the first example code block from the SKILL.md body.
4. Render the MDX page from reference/mdx-template.md (see that file for the full template) into .yoke/sync-docs-tmp/skills/<name>.mdx.
5. Always include the raw SKILL.md body verbatim inside a <details><summary>Full instructions</summary> … </details> block.

After every skill is rendered:

6. Render the README block to .yoke/sync-docs-tmp/readme-block.md as a 3-column markdown table:

   | Command        | What it does           | Output   |
   | -------------- | ---------------------- | -------- |
   | `/yoke:<name>` | <one-line description> | <Output> |

   The one-line description is the first sentence of the SKILL.md description (everything up to the first . ). The Output column is the value from docs/<name>.md's **Output:** line when present, else —.

7. Render the CLAUDE.md block to .yoke/sync-docs-tmp/claudemd-block.md as a bullet list matching the current style at CLAUDE.md:62-78:

   - `/<name>` — <one-line description>

Phase 4 — Sentinel check

For each of README.md and CLAUDE.md, count line-anchored occurrences of each marker:

grep -cE "^<!-- yoke:skills:start -->\$" README.md   # must be 1
grep -cE "^<!-- yoke:skills:end -->\$"   README.md   # must be 1

Anchor to line boundaries — the catalog table itself may mention the marker text inside cells (the sync-docs row literally describes the markers). Only standalone-line occurrences count as sentinels.

The standalone start marker line must come before the standalone end marker line.

On any failure:

Markers missing or unbalanced in <file>.
Add exactly one <!-- yoke:skills:start --> and one <!-- yoke:skills:end -->
around the catalog block; re-run.

In --check mode → exit non-green. In write mode → abort before any write.

Phase 5 — Write or diff

Write mode

For each per-skill MDX in .yoke/sync-docs-tmp/skills/:

cp .yoke/sync-docs-tmp/skills/*.mdx site/src/content/docs/skills/

For README.md: replace the byte range between the two sentinels with the contents of .yoke/sync-docs-tmp/readme-block.md, surrounded by a single blank line on each side. Leave every other byte unchanged.

For CLAUDE.md: same procedure with .yoke/sync-docs-tmp/claudemd-block.md.

Then normalize the output through prettier so the round-trip matches what husky's lint-staged hook would produce on commit:

pnpm exec prettier --write \
  README.md CLAUDE.md \
  site/src/content/docs/skills/*.mdx

Send the completion notification:

bash ${CLAUDE_PLUGIN_ROOT}/lib/notify.sh \
  --type STAGE_COMPLETE \
  --skill sync-docs \
  --title "Docs synced" \
  --body "<N> MDX pages written; README + CLAUDE.md catalog blocks regenerated"

Check mode

Normalize the rendered tree through prettier first (so the comparison is fair against the prettier-formatted live tree):

pnpm exec prettier --write \
  .yoke/sync-docs-tmp/skills/*.mdx \
  .yoke/sync-docs-tmp/readme-block.md \
  .yoke/sync-docs-tmp/claudemd-block.md

Then compare the tmp tree against the live tree:

diff -r .yoke/sync-docs-tmp/skills/ site/src/content/docs/skills/

Extract the byte range between sentinels from README.md and CLAUDE.md; compare against the rendered blocks. List every file with drift.

On any drift:

Docs drift detected in: <files, newline-separated>
Run `/sync-docs` to regenerate, review the diff, commit, and retry.

Exit non-green.

When the live tree matches the tmp tree byte-for-byte → exit zero.

Rules

• Catalog membership: every directory under skills/ that contains a SKILL.md (15 today). Never include .claude/skills/* skills (yoke-create, yoke-release, yoke-validate).
• Sentinels are required. Refuse to write when they are missing or unbalanced. Never auto-insert.
• Touch only the bytes between the sentinels in README.md and CLAUDE.md. Every other byte must round-trip unchanged.
• The raw SKILL.md inside <details> is the source of truth — never edit it during render.
• Idempotence: running /sync-docs then /sync-docs --check must produce no diff. If the check call reports drift after a fresh write, the renderer is non-deterministic — fix the renderer before relying on the release gate.
• Render artifacts live in .yoke/sync-docs-tmp/ (gitignored). Never commit them.

Reference

• reference/mdx-template.md — the 7-section per-skill MDX template.
• reference/sync-spec.md — sentinel rules, enumeration rules, check-mode contract, idempotence rule.

Example

/sync-docs

→ Writes site/src/content/docs/skills/<name>.mdx for all 15 skills, regenerates the README and CLAUDE.md catalog blocks.

/sync-docs --check

→ Exits zero when everything is in sync; exits non-green and lists the affected files on any drift.

Connections

/yoke-create  → /sync-docs  (Phase 6b tail; regenerates catalog for the new skill)
/yoke-release → /sync-docs --check  (Phase 0f gate; halts release on drift)
