skill-author is a skill for Claude Code, Codex from autoworks-ai/autovault. It costs 28 tokens per session (1,473 once invoked), scanned A, original, MIT.

A packaging and validation skill for preparing an existing skill draft or skill folder for AutoVault, the system described here for reviewing and installing skills.

In plain words
What is it for?
Use it to inspect skill metadata and bundled files, declare capabilities, validate a package, resolve admission issues, or prepare it for AutoVault installation.
Why use it?
It helps catch schema, resource, capability, security, duplication, and installation problems before submission.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

skill-author scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AutoVault Skill Packager

Prepare an existing SKILL.md or skill directory for AutoVault admission. This skill is about AutoVault packaging: schema correctness, bundle membership, capability declarations, validation, deduplication, and signed installation.

Scope

Use this skill when:

  • a workflow or draft already exists and needs valid AutoVault frontmatter;
  • a bundle has support files that must be inventoried and declared;
  • an AutoVault validation, security, or dedup result needs remediation; or
  • a reviewed bundle is ready for propose_skill or add_skill.

Do not use it for open-ended workflow invention, trigger design, or general skill-writing pedagogy. Use the host-native skill-creator or equivalent design tool first, then return here once there is a concrete draft to package.

1. Check for an existing capability

If the AutoVault compatibility tools are connected, search with get_skill({query: "specific workflow nouns"}). Prefer extending or reusing a good match over adding another near-duplicate.

When the MCP tools are absent, inspect the host's normal visible skill directory instead. AutoVault-managed skills are synced into those native directories, so filesystem discovery is sufficient and the missing MCP server is not an error.

2. Inventory the complete bundle

Treat the skill directory as one unit:

  • SKILL.md is the entry point.
  • Every regular sibling file under the directory is a resource.
  • Exclude OS/editor metadata and generated caches.
  • Reject symlinks, path traversal, device files, and other non-regular entries.
  • Review executable resources as carefully as the skill body.

For a GitHub source, AutoVault fetches all regular sibling files beneath the selected skill directory at one immutable commit. It does not rely on the upstream author having declared every file. Missing resources declarations are synthesized during normalization, and the install response reports inferred_resources for review.

3. Normalize frontmatter

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
