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-add 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 1mo 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 Add

Wraps cc:cc-skills skill.

Run the skill's scaffold operation. Pass $ARGUMENTS unchanged and retain the request's scope, context, and authorization. Scaffold a seed and follow the skill's authoring and verification workflow. Lifecycle add maps to scaffold; the CLI's skill add operation installs an existing skill.

Skill(skill="cc:cc-skills", args="scaffold $ARGUMENTS")

If the native Skill mechanism is unavailable, read the installed cc-skills skill and follow its workflow. Use the equivalent CLI for the deterministic lane; CLI output does not replace semantic review:

superskill skill scaffold $ARGUMENTS

Return the delegated result and exact failures, including relevant verification and limitations.

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.
