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

security-audit 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 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.

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.

Security Audit

Systematic security review of a project covering dependency vulnerabilities, credential exposure, common code vulnerabilities, and configuration hardening.

When to Use

  • Before a release or deployment
  • After adding new dependencies
  • When onboarding to a new codebase
  • Periodic security reviews
  • After receiving a vulnerability report

Audit Checklist

1. Credential and Secret Scanning

Check for exposed secrets in the codebase:

# Check for common secret patterns in tracked files
git grep -n -i -E '(api_key|apikey|secret|password|token|credential|private_key)\s*[:=]' -- ':!*.md' ':!*.lock'

# Check for .env files tracked in git
git ls-files | grep -i '\.env'

# Check .gitignore covers sensitive files
for f in .env .env.local credentials.json secrets.yaml; do
  git check-ignore "$f" 2>/dev/null || echo "WARNING: $f not in .gitignore"
done

Files that must never be committed:

  • .env, .env.* (environment variables)
  • credentials.json, service-account.json (cloud credentials)
  • *.pem, *.key (private keys)
  • *.p12, *.pfx (certificates with private keys)

2. Dependency Vulnerability Scan

Python:

uv run pip-audit

JavaScript/TypeScript:

bun pm audit
# or check with npm for broader database
npm audit --omit=dev

Go:

govulncheck ./...

Review results against the severity rubric (shared with the dependency-auditor agent):

  • Critical: exploitable now or actively exploited (leaked live credential, known-exploited CVE in a reachable path). Must fix before release; blocks release-prep.
  • High: known vulnerability with a plausible attack path. Fix before the next release.
  • Medium: vulnerability with mitigating factors, or a major-version lag on a security-relevant package. Fix within the sprint.
  • Low: outdated without known vulnerabilities; license concerns to review. Track in backlog.

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.

security-audit is a skill published in the GitHub repository neuromechanist/research-skills (45 stars, last pushed 9d ago), licensed BSD-3-Clause. It adds 83 tokens to every session and 1,375 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
