Skill Sync

Skill Sync — Detect & Apply CLI Changes

After a new mmk CLI version ships, run this skill to find what changed, update the SKILL.md files, and raise a PR automatically.

Diff-only mode: If the user says "just show the diff" or "dry run", stop after Phase 4.

Phase 1: Upgrade & Version Check

First, upgrade the CLI to the latest version, then confirm the version:

mmk upgrade
mmk version -o json

Report the upgraded version (old → new) to the user before continuing. If already on the latest version, report the current version and proceed.

Phase 2: Crawl CLI Command Tree

Build the full command tree by traversing --help at every level.

Step 2a — Top-level services

mmk --help

Parse the output to extract service names (e.g., notion, paymint, threads, youtube, auth, config). Skip auth, config, version, completion, doctor, plan, status, upgrade, and help — they are not documented as skills.

Step 2b — Sub-commands per service

For each service:

mmk {service} --help

Extract sub-command names (resource groups like page, workspace, team, etc.).

Step 2c — Commands per sub-command

For each sub-command:

mmk {service} {sub} --help

Extract individual commands (e.g., invite, revoke, list).

Step 2d — Flags per command

For each command:

mmk {service} {sub} {command} --help

Extract flags, their defaults, and descriptions. Also capture any usage examples in the help output.

Build a data structure like:

{service} -> {sub} -> {command} -> [flags, description, examples]

Phase 3: Inventory Existing Skills

Read all existing SKILL.md files to build the documented command inventory.

Step 3a — Find all skill files

Use Glob to find mmk-*/SKILL.md in the repo root.

Step 3b — Parse each sub-skill

For each sub-command skill (mmk-{service}-{sub}/SKILL.md):

• Extract the ## {command} sections
• Extract documented flags under each command
• Build a parallel data structure matching Phase 2's format

Step 3c — Parse root skills

For each root skill (mmk-{service}/SKILL.md):

• Extract the Sub-Command Skills table
• Note the command counts listed

Step 3d — Parse shared skill

Read mmk-shared/SKILL.md and extract the Command Reference section with counts.

Step 3e — Parse README

Read README.md and extract the Skill Inventory table and Architecture tree with counts.

Phase 4: Diff Report

Compare the CLI tree (Phase 2) against the skill inventory (Phase 3). Report changes in this format:

## Skill Sync Report — mmk v{version}

### New Services
| Service | Sub-commands | Commands |
|---------|-------------|----------|
(or "None")

### New Sub-commands
| Service | Sub-command | Commands |
|---------|------------|----------|
(or "None")

### New Commands
| Service | Sub-command | Command | Flags |
|---------|------------|---------|-------|
(or "None")

### Changed Flags
| Service | Sub-command | Command | Change |
|---------|------------|---------|--------|
(or "None")

### Removed Commands (MANUAL REVIEW REQUIRED)
| Service | Sub-command | Command | Current Location |
|---------|------------|---------|-----------------|
(or "None")

### Count Mismatches
| Location | Documented | Actual |
|----------|-----------|--------|
(or "All counts consistent")

Important: Never auto-delete removed commands. Flag them for the user's manual review.

If the user requested diff-only mode, present the report and stop here.

If there are no changes (no new services, sub-commands, commands, changed flags, or removed commands), report "No changes detected" and stop. Do not proceed to Phase 5.

Otherwise, proceed immediately — do not ask for confirmation.

Phase 5: Apply Changes

Follow the CLAUDE.md checklists precisely. Read CLAUDE.md first to get the exact conventions.

Update order (dependencies flow downward):

1. New service (if any) — follow "Adding a New Service" checklist:

   • Create root folder mmk-{service}/SKILL.md using root template
   • Create sub-skill folders per granularity rules
   • Update mmk-shared/SKILL.md — add to Command Reference
   • Update README.md — inventory table, architecture tree, install section

2. New sub-command (if any) — follow "Adding a New Sub-Command Skill" checklist:

   • Create folder mmk-{service}-{sub}/SKILL.md using sub-command template
   • Update root skill — add row to Sub-Command Skills table, adjust count
   • Update README.md — inventory table, architecture tree, skill list
   • Update mmk-shared/SKILL.md — adjust count in Command Reference

3. New command (if any) — follow "Adding a New Command" checklist:

   • Add ## {command} section to the correct mmk-{service}-{sub}/SKILL.md
   • Update root skill — adjust command count
   • Update mmk-shared/SKILL.md — adjust count
   • Update README.md — adjust count

4. Changed flags — update the flag documentation in the relevant sub-skill

5. Removed commands — present to user for manual decision. Do not auto-delete.

Template references

When creating new files, use the templates defined in CLAUDE.md:

• Sub-Command Skill template for mmk-{service}-{sub}/SKILL.md
• Root Skill template for mmk-{service}/SKILL.md

Always include:

• Correct frontmatter (name, description, allowed-tools)
• > **Prerequisite:** line linking to mmk-shared
• -o json reminder
• See Also section with links to shared + parent + siblings

Phase 6: Verify

Run the CLAUDE.md verification checklist:

6a — Link integrity

cd skills && for f in mmk-*/SKILL.md; do
  dir=$(dirname "$f")
  # Extract links from href part only: ](../mmk-xxx/SKILL.md)
  grep -oE '\]\(\.\./mmk-[^)]+/SKILL\.md\)' "$f" 2>/dev/null | sed 's/^](\(.*\))$/\1/' | while read link; do
    resolved="$dir/$link"
    while echo "$resolved" | grep -q '[^/]*/\.\./'; do
      resolved=$(echo "$resolved" | sed 's|[^/]*/\.\./||')
    done
    [ ! -f "$resolved" ] && echo "BROKEN: $f -> $link"
  done
done

6b — Frontmatter check

Every SKILL.md must have name, description, and allowed-tools (except mmk-shared).

6c — Prerequisite check

Every skill except mmk-shared must have a > **Prerequisite:** line.

6d — Count consistency

Verify that command counts agree across:

• Root skill Sub-Command Skills tables
• mmk-shared/SKILL.md Command Reference
• README.md Skill Inventory table and Architecture tree

Report any failures and fix them.

Phase 7: Commit & Pull Request

After verification passes, automatically create a branch, commit, push, and open a PR.

7a — Create branch and commit

git checkout -b skill-sync/v{version}
git add -A skills/ README.md
git commit -m "feat: sync skill docs with mmk CLI v{version}"

Use a descriptive commit message summarizing the changes (e.g., "feat: add notion page get and update commands for v{version}").

7b — Push and create PR

git push -u origin skill-sync/v{version}

Create the PR using gh with the skill-sync template. Fill in the template placeholders from the Phase 4 diff report:

gh pr create \
  --title "feat: skill sync for mmk v{version}" \
  --body "$(cat <<'EOF'
## Summary
- Sync skill docs with mmk CLI **v{version}** (commit `{cli_commit}`)
- {one-line change summary, e.g., "Add 2 new notion page commands: get, update"}

## Skill Sync Report

### New Services
{new_services_table or "None"}

### New Sub-commands
{new_subcommands_table or "None"}

### New Commands
{new_commands_table or "None"}

### Changed Flags
{changed_flags_table or "None"}

### Removed Commands (MANUAL REVIEW)
{removed_commands_table or "None"}

## Files Changed
{bullet list of modified files}

## Test plan
- [ ] Verify new commands: `mmk {command} --help` matches documented flags
- [ ] Verify link integrity: all `../mmk-*/SKILL.md` paths resolve
- [ ] Verify command counts consistent across root, shared, and README
- [ ] Verify frontmatter: name, description, allowed-tools present
