Find credentials, API keys, tokens, private keys, and high-entropy strings in target/. Combines gitleaks, trufflehog, detect-secrets, ggshield, and manual entropy grep. Triages each hit for live vs. test vs. revoked.

Conduct a passive, read-only forensic analysis of a potentially malicious source-code tree. Use this skill when the user suspects a repository, archive, or directory contains hidden payloads, C2 code, obfuscated droppers, or compromised build configs (e.g. injected `tailwind.config.js`, trojaned `package.json` postinstall, suspicious base64 blobs). Produces a full report: attacker signature, payload location, statically decrypted IoCs (C2 IPs, ports, paths, XOR keys, drop paths, exfil endpoints).
Render reports/findings.json + reports/SUMMARY.md into a single-file, self-contained reports/SUMMARY.html whose visual quality matches the /reports/example-summary page on coldvault.dev. No external fonts, no JS framework, no network fetches — the user can double-click the file, email it, or host it anywhere.
Audit GitHub Actions / GitLab CI / CircleCI / Azure Pipelines workflows shipped in target/. Flags the high-risk patterns that have caused real-world supply-chain compromises (pwnrequest, pull_request_target, unpinned actions, secret exfiltration, script-injection via PR title/body).
Inventory the suspect repository (languages, frameworks, package managers, entry points, build system, CI) before any scan. Always run this first — subsequent skills depend on its output.
Inspect cryptographic code for timing leaks. Flags variable-time comparisons on secrets, early-exit loops, and library calls known to be variable-time. Limited static scope — the definitive check is micro-benchmarks on compiled binaries, but ~70% of timing bugs show up in source review.
Map the attack surface of target/ — HTTP routes, CLI commands, exported library symbols, message-queue consumers, GitHub Actions triggers, IPC sockets. Produces reports/entry-points.md.

For every candidate secret:
| Signal | Severity |
|---|---|
| Matches a real regex + high entropy + in a non-test path | HIGH |
| Matches a real regex + in a test / example | LOW (report anyway) |
Verified live (trufflehog --verification) | CRITICAL |
| In git history but not in HEAD | MEDIUM (rotation still required) |
.env.example, fake-looking | INFO (don't report) |

without explicit analyst consent — it can tip off the attacker (telemetry),
and can cost real money on some providers.reports/ — redact to first/last
