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 C, and why

fusion-skills skills-greenkeeping.instructions.md scanned grade C with 2 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 12d 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.

Skills greenkeeping instructions

Apply when maintaining skills in skills/**.

Goal

Keep skill catalog discoverable, current, high-quality, secure, owned.

Greenkeeping activities and triggers

Run greenkeeping when at least one of the following happens:

  • A PR changes skills/** content (SKILL.md, assets/**, references/**, scripts/**).
  • A new skill is added or an existing skill is moved, deprecated, or removed.
  • MCP server requirements or compatibility expectations change.
  • A scheduled maintenance sweep is due (recommended cadence: at least monthly).
  • A reliability or security incident identifies stale/unsafe skill guidance.

For each greenkeeping run, cover all activity lanes:

# Lane Focus
1 Discovery audit Activation cues, tags, findability
2 Currency audit Metadata, dependencies, compatibility
3 Quality audit Structure, completeness, references
4 Security audit Unsafe patterns, secret exposure risk
5 Ownership and lifecycle audit Owner/sponsor, status, deprecation path
6 Workflow-policy alignment audit Governance handoff, policy drift

Metadata standards and currency checks

Required frontmatter:

  • name
  • description
  • metadata.version

Required ownership metadata:

  • metadata.owner (required): primary accountable maintainer.
    • Use a stable GitHub identity (@user or @org/team).
    • Avoid personal names without GitHub identity.
  • metadata.sponsor (optional): backup accountability owner (team or maintainer).
  • metadata.deprecated_at (required for skills in skills/.deprecated/): date the skill was deprecated in YYYY-MM-DD format. Validated by CI.

Discovery and currency checks:

  • description clearly states what the skill does and when to use it.
  • metadata.tags remains present and relevant to current scope.
  • metadata.mcp.required and metadata.mcp.suggested match actual tool needs.
  • metadata.role, metadata.orchestrator, and metadata.skills remain internally consistent.
  • compatibility text (if present) reflects current prerequisites.
  • Existing skill metadata.version is not manually bumped in regular PRs; use changesets and release automation flow.

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.
