repo-sentinelFull security audit for public repositories across 12 attack surfaces: git history, secrets, CI/CD, containers, dependencies, licenses.
Repo Sentinel is an agent skill from Mathews-Tom/armory. Full security audit for public repositories across 12 attack surfaces: git history, secrets, CI/CD, containers, dependencies, licenses. Triggers on: "push to GitHub", "make repo public", "open source this", "is this safe to push", "release audit", "secret leaks".
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `evals/cases.yaml`, `references/attack-surfaces.md` and `references/pre-release-checklist.md`).
It sits in Security, covering Threat modeling, Git workflow and Security review. It works with GitHub and Git. The repository describes itself as: Curated, production-grade skills for AI coding agents. Battle-tested workflows for developers who use AI seriously. The licence is MIT.
Read from SKILL.md and the folder at commit 4594fb7. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
gitghFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use git and gh, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Repo Sentinel loads about 2.2k tokens when it runs, and up to ~17k if it reads all its reference files. Until then it costs about 69 tokens; SKILL.md has 953 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/repo-sentinel/SKILL.md (or your agent's skills folder). This skill also uses 6 other files; get the full folder from GitHub.Everything in a public repo is permanent attacker surface. This skill defines what belongs in a public repo, what does not, how to detect violations across 12 attack surfaces, how to remediate when the boundary is violated, and how to enforce continuously.
This skill uses bundled reference files for detailed patterns and templates. Read them as needed:
| File | When to read |
|---|---|
references/attack-surfaces.md | When auditing any surface — full definitions for Surfaces 0–12 |
references/scan-patterns.md | When running any audit (fast-path or full) — contains all detection commands |
references/pre-release-checklist.md | When running the Pre-Release Audit (Stage 4) — §4.1–§4.8 readiness checklist |
references/templates.md | When setting up enforcement, generating .gitignore, or creating CI gates |
references/remediation.md | When fixing findings or scrubbing history — contains all fix procedures |
gh CLI installed and authenticated (gh auth status must pass) — required for GitHub-specific surface checks (Surface 10)git objects; non-git directories are out of scopetrufflehog or gitleaks — optional but strongly recommended for Surface 0 (git history) secret detection with entropy analysis; without them, fall back to git log -p grep patterns from references/scan-patterns.md--depth N) will miss history secrets; warn the user if a shallow clone is detectedtrufflehog/gitleaks are unavailable, note this in the audit header and describe the reduced confidence in Surface 0 coverage.api_key with a placeholder value is LOW, not CRITICAL.The public/private boundary is a one-way valve. Once a byte reaches a public remote — via
push, PR, issue, wiki, release asset, or GitHub Pages — assume it is indexed, cached, mirrored,
and archived permanently. git push --force, PR deletion, issue edits, and release removal do
NOT guarantee erasure. Scraping infrastructure (GitHub Archive, GH Torrent, Software Heritage,
Google Cache, Wayback Machine, and dozens of proprietary security scanners) operates continuously
with sub-hour latency.
Decision framework for every artifact:
| Question | If YES → | If NO → |
|---|---|---|
| Could this help an attacker who has no other access? | EXCLUDE | Continue |
| Does this reveal internal topology not inferable from public signals? | EXCLUDE | Continue |
| Does this contain values that grant access to anything? | EXCLUDE | Continue |
| Does this violate a license obligation or expose legal risk? | EXCLUDE | Continue |
| Would removing this reduce the repo's utility to legitimate users? | INCLUDE (if above = all NO) | EXCLUDE |
When in doubt, exclude. False negatives (leaked secrets) are catastrophic and irreversible. False positives (over-redaction) are trivially correctable.
Full definitions — what belongs, what doesn't, why it leaks, detection approach — for Surfaces 0
through 12 are in references/attack-surfaces.md. Read that file when scoping or scoring any
audit. Scan commands per surface live in references/scan-patterns.md; remediation procedures
in references/remediation.md.
All findings are classified by severity. The classification drives action priority:
| Severity | Criteria | Action |
|---|---|---|
| CRITICAL | Active credential exposure, private key, auth token | Block push. Fix immediately. |
| HIGH | Infrastructure/topology enabling targeted attack | Resolve before push. |
| MEDIUM | Information leakage aiding reconnaissance | Fix in next commit. |
| LOW | Hygiene, style, redundancy issues | Fix at convenience. |
CRITICAL and HIGH in git history → full history scrub + credential rotation required.
Use when pushing a single file or small changeset. Scans only staged changes, not the full repo.
Read references/scan-patterns.md § Fast-Path for the commands.
Run before making any repo public or before first push to a public remote.
Read references/scan-patterns.md § Full Audit for the complete 20-check sequence, the
Quick-Reference Scan Commands block, and the audit output format.
When preparing a repo for open-source release, run this 4-stage pre-release audit instead of the surface-based audit. Each stage emits PASS / WARN / FAIL with actionable remediation. Hard blockers in stages 1–3 halt the pipeline. Stage 4 produces advisory output.
Stage 1: Sensitive Assets [HARD BLOCKER] → Surfaces 0–4, 8–9
Stage 2: Legal & Compliance [HARD BLOCKER] → Surface 11
Stage 3: Public Surface Hygiene [HARD BLOCKER] → Surfaces 4–7, 9–10
Stage 4: Contribution & Release [SOFT BLOCKER] → Surface 12 + Pre-Release ChecklistRun stages sequentially. Report results in a structured audit table at the end. Stage 4
checklist items (§4.1–§4.8) are in references/pre-release-checklist.md.
Shift-left prevention is the highest-leverage action. Read references/templates.md for
ready-to-use pre-commit config, GitHub Actions workflow, and .gitignore generator.
When secrets have already been committed. Read references/remediation.md for the full
triage decision tree, git filter-repo commands, BFG fallback, post-scrub protocol, and
.gitignore generation guidance.

Full security audit for public repositories across 12 attack surfaces: git history, secrets, CI/CD, containers, dependencies, licenses. Repo Sentinel is an agent skill from Mathews-Tom/armory. Full security audit for public repositories across 12 attack surfaces: git history, secrets, CI/CD, containers, dependencies, licenses.
Repo Sentinel fits situations like: : push to GitHub; make repo public; open source this; is this safe to push.
Run `npx skills add Mathews-Tom/armory --skill repo-sentinel -a claude-code`. Or copy the skill folder (skills/repo-sentinel in Mathews-Tom/armory) into .claude/skills/repo-sentinel in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Mathews-Tom/armory --skill repo-sentinel -a codex`. Or copy the skill folder (skills/repo-sentinel in Mathews-Tom/armory) into .agents/skills/repo-sentinel in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Mathews-Tom/armory --skill repo-sentinel -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/repo-sentinel, .gemini/skills/repo-sentinel, .github/skills/repo-sentinel and .opencode/skills/repo-sentinel in your project.
Going by SKILL.md and its folder, Repo Sentinel needs the command-line tools its instructions call (git and gh).
SKILL.md contains no URLs. Its commands use git and gh, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Repo Sentinel is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.2k tokens (SKILL.md is roughly 8.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 14k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Repo Sentinel: Release (312362115/claude, 107 stars), Gpg Multi Key (Prorise-cool/Claude-Code-Multi-Agent, 306 stars), GitHub Actions Hardening (github/awesome-copilot, 40k stars) and Qv Devops PR Review (tetherto/qvac, 685 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
