Output of apm pack, sync-plugin-content.sh --all and sync-marketplace-mirror.sh against this round's source changes. No file here is hand-edited. Carries the version bumps and marketplace owner.email into the compiled manifests, the disallowedTools frontmatter and doc corrections into the flat mirrors, and changes plugins/bin/.github/plugin/plugin.json's mcpServers from the inlined server object to the ".mcp.json" pointer. That last file also returns to 0644: the previous re-injection wrote it through mktemp and carried 0600 across, which no gate could see because the mode check did not cover .github/plugin/ and git tracks only the exec bit. .agents/plugins/marketplace.json is unchanged and that is correct -- apm's codex profile carries neither version nor owner keys, so nothing in this round reaches it.

skill-author
Author and refine skills conforming to the agentskills.io specification — create new skills from scratch or apply improvement signals to existing ones.
What it does
Routes to one of two flows based on context: if no skill directory exists at the target path, it scaffolds the directory from annotated templates, fills in SKILL.md and supporting files, and validates the result. If an existing skill directory and improvement signals are both present, it groups those signals by root cause and applies targeted edits, then re-validates. In both flows, bumps the skill's metadata.version when present (minor for create, patch for improve).
Before you start
- Run
/grill-meto resolve design decisions before creating a new skill - Collect domain research, examples, and constraints
- Know the skill name (kebab-case) and destination path
Placement
scripts/new-skill.sh resolves the mode automatically by walking up from the given path — see SKILL.md Step 1 for the full algorithm.
| Mode | Path | Chosen when |
|---|---|---|
| Standalone | <path>/<name>/ |
No apm.yml with a top-level type: field is found walking up from <path>, before hitting .git or the filesystem root |
| Package (APM) | <package-root>/.apm/skills/<name>/ |
A type-bearing apm.yml is found at or above <path> — <path> just needs to be somewhere inside the package |
If the destination resolves inside an APM package, read references/deployment-modes.md — self-containment rules apply to apm compile output the same way they applied to plugin cache isolation.

Rows marked (source-only) exist in the authoring source (.apm/skills/skill-author/) but are
not present in an installed plugin: scripts/sync-plugin-content.sh strips
<category>/<name>/tests when it generates the flat mirror, because these are dev-time fixtures no
plugin host needs to discover (ADR-0017). Run them from a repo checkout, not from an install. The
assets/templates/tests/README.md row above is not source-only — the exclusion is depth-scoped
to <category>/<name>/tests, so the scaffolding template tree ships intact, which
scripts/new-skill.sh depends on at runtime.
