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

Create Cowork Skill Package 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 7d 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

Create Cowork Skill Package

Inputs

  • {{name}}: Cowork skill name
  • {{workflow}}: Repeatable workflow and desired result
  • {{sources}}: Permitted source types
  • {{outputDir}}: Package output directory

Requirements

  1. Read .github/skills/development/cowork-skill-creator/SKILL.md in full before authoring files.
  2. Convert the request and attached context into a clear purpose, trigger, inputs, ordered process, fixed output format, boundaries, and quality checks.
  3. Create {{outputDir}}/<skill-name>/SKILL.md with valid name and description frontmatter, and keep it within the maximum of 20000 characters.
  4. Create and populate all companion directories with workflow-specific content:
    • assets/ with the exact reusable output template or sample structure
    • references/ with normal, missing-input, conflicting-input, non-trigger, and consequential-action test cases
    • scripts/ with a deterministic validator or helper appropriate to the output contract
  5. Do not leave TODO markers, generic placeholders, secrets, credentials, personal data, customer-sensitive data, or unsupported claims.
  6. Require human review before sending, publishing, deleting, approving, or taking another consequential action.
  7. Run .github/skills/development/cowork-skill-creator/scripts/New-CoworkSkillPackage.ps1 against the completed source directory.
  8. Verify the zip contains SKILL.md at its root and populated assets/, references/, and scripts/ folders.
  9. Return the generated zip path and a concise list of packaged files. The final deliverable must be the zip file, not only a Markdown response or source directory.

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.
