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

dependency-checker 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/main.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

This is a script-strategy skill. The script in scripts/main.sh runs npm audit --json inside the directory supplied via SKILLFORGE_INPUT (or the SkillForge temp cwd if input is empty), parses the output with jq, and prints a one-line summary to stdout.

Output format (one line):

high=<N> critical=<M> total=<T> packages=<P>

When npm audit errors (no package.json, no node_modules, network failure), the script prints error=<reason> and exits 0 — SkillForge returns the line as a successful invocation, the consuming agent decides what to do with the diagnostic.

Prerequisites:

  • config.security.allowScripts: true in the SkillForge persisted config.
  • npm and jq on the host's resolved PATH (on POSIX, the SandboxRunner restricts PATH to /usr/bin:/bin — install jq system-wide or override DEFAULT_PATH for this skill).
  • SKILLFORGE_INPUT set to an absolute path of the project to audit, or unset to audit the temp cwd (which will report no package.json — usually pass the path explicitly).
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
