security-scan

security-scan is a skill for Claude Code, Codex from fmind/dotfiles. It costs 34 tokens per session (1,867 once invoked), scanned A, original, MIT.

A repository security checker that uses Trivy and Gitleaks to find vulnerable dependencies, unsafe configuration, leaked secrets, license issues, and problems in container images or Git history.

In plain words
What is it for?
Use it to scan source code, Docker and infrastructure files, dependencies, container images, staged changes, and Git history, then review the reported findings.
Why use it?
It brings several security checks into one review and can find secrets that were committed and later deleted.

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-scan 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.

Security Scanning

Scan a repository (and its images) for vulnerabilities, misconfigurations, secrets, and license issues. Layers Trivy (config: dot_config/trivy/trivy.yaml — HIGH/CRITICAL, ignore-unfixed, scanners: vuln/misconfig/secret/license) over gitleaks for deep git-history secret detection, complementing the language-native scanners (govulncheck, pip-audit).

Workflow

  1. Repository scan (dependencies, misconfig, secrets, licenses in one pass):
    trivy --config trivy.yaml fs .   # always pass --config: an exported TRIVY_CONFIG outranks ./trivy.yaml — see Gotchas
    
  2. Targeted config scan (Dockerfiles, Kubernetes manifests, Terraform — optional if already done via trivy fs):
    trivy --config trivy.yaml config .
    
  3. Secrets in git history (deeper than a working-tree scan — catches committed-then-deleted secrets):
    mise run check:leaks          # recent commits (this repo caps at the last 10)
    mise run check:leaks --staged # pre-commit scope
    gitleaks git --verbose        # full history — the actual audit
    
  4. Container image scan (after a build — see containerize):
    trivy --config trivy.yaml image <registry>/<image>:<tag>
    
  5. Language-native depth (already wired into mise run check as check:vuln):
    • Go: go tool govulncheck ./...
    • Python: uv run pip-audit
  6. Triage: summarize findings by severity, separate fixable from unfixed, and propose the minimal upgrade/patch or a justified ignore.

Mise Task Integration

Expose security scans in the project's canonical task vocabulary (mise.toml) per the mise skill. check:leaks (gitleaks) and check:scan (trivy fs, one pass over vuln/misconfig/secret/license) follow the same pattern in every repo; check:vuln is the language-native scanner where one exists (govulncheck/pip-audit — see go-stack/python-stack) and is omitted entirely in polyglot or config-only repos with no native scanner — check:scan's trivy fs already covers vulnerabilities there:

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-scan is a skill published in the GitHub repository fmind/dotfiles (4 stars, last pushed 1mo ago), licensed MIT. It adds 34 tokens to every session and 1,867 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
