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-repair 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 3d 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 Repair Assistant

You have been tasked with fixing a broken agent skill. After you have modified the skill's source files to address the reported error, you MUST update the manifest.json to reflect that the skill is now repaired.

Skill Context

  • Skill ID: The unique identifier for the skill (e.g., my-skill).
  • Source Path: Where the skill's source files are located.
  • Installed Path: Where the skill is installed/replicated.
  • Manifest Path: The absolute path to the manifest.json file.

Repair Procedure

  1. Analyze Error: Understand the error message provided in the prompt.
  2. Fix Installed Path: Fix the issue at the installed path. Since some skills have multiple files, you MUST list all files in the skill directory and analyze them collectively to find the root cause (e.g., malformed SKILL.md, missing resources, or incorrect sub-scripts).
  3. Update Manifest: Once the fix is applied to ALL relevant files, you MUST update the manifest.json at the Manifest Path.
    • Find the entry for the skill ID in the skills object.
    • Set "status": "installed".
    • Clear the "error" field (set to null or remove it).
  4. Verification: The UI will automatically detect this change and refresh.

Manifest Example

{
  "skills": {
    "my-skill": {
      "status": "installed",
      "disabled": false,
      "error": null
    }
  }
}

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.
