skill-authoring

skill-authoring is a skill for Claude Code, Codex from pockebot/openpocket. It costs 27 tokens per session (329 once invoked), scanned A, original, MIT.

A guide for turning a rough agent skill into a reusable `SKILL.md` instruction file. It defines when the skill applies, what it needs, how it runs, and what to do when something fails.

In plain words
What is it for?
It is for writing triggers, preconditions, step-by-step procedures, fallback paths, failure handling, and completion criteria for agent skills.
Why use it?
It makes skill instructions more predictable and easier to validate, reuse, and follow in different situations.

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-authoring 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 5d 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.

What it actually says

skill-authoring

Use this skill when converting a rough draft into a production-ready skill document.

Goal

Transform noisy step traces or draft markdown into a strict SKILL.md that is:

  1. deterministic to execute
  2. explicit about when to trigger
  3. explicit about failure handling
  4. valid against strict skill validation rules

Required Structure

  1. Frontmatter:
    • name (kebab-case, matches directory)
    • description (one concise sentence)
    • optional metadata JSON for triggers/requirements
  2. Body sections:
    • When To Use
    • Preconditions
    • Procedure
    • Failure Handling
    • Completion Criteria

Refinement Rules

  1. Replace fragile coordinates with semantic UI targets whenever possible.
  2. Keep each procedure step one atomic action.
  3. Add at least one fallback path for common blockers (auth wall, empty state, loading timeout).
  4. If personal data is required, add request_human_auth guidance before UI actions.
  5. Keep language concise and executable.

Validation Gate

Before promotion:

  1. Run strict skill validation.
  2. If validation fails, keep as draft and report issues.
  3. Promote only validated output.

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.
