| name | supply-chain-audit |
| description | Software supply chain audit — dependencies (CVEs, maintenance, licenses, transitive risk), build/CI integrity (SHA-pinned actions, lockfile, CI-only release), artifact integrity (checksums, signing, SBOM). Triggers on: "/supply-chain-audit", "supply-chain-audit", "dependency audit". Run before adding a dep, before a release, or for periodic review. Reports; does not change deps unless asked. |
Supply-Chain Audit
Language: Generate EVERYTHING at runtime in the user's language — questions, answer options, menu labels, recommendations, report narrative. Detect from their messages; never default to English just because this file is English. English is allowed only for technical terms: commands, paths, code identifiers, severity labels (CRITICAL/HIGH/MEDIUM/LOW), and tier names (Light/Standard/Heavy).
Audit what the project trusts: deps, build pipeline, shipped artifact. Report; do NOT change deps unless asked.
1. Dependencies
- Scope — honor
.coalmine.json packageManifests if set: scan exactly those manifest/lockfile paths; else infer by inspecting the repo.
- CVEs — run ecosystem auditor; cross-check every hit in GHSA/OSV/NVD. Cite advisory ID + affected range + fixed version. (Invoke source-grounding — never from memory.)
- Maintenance — last release, commit recency, bus-factor, archived/deprecated flag.
- License — flag copyleft inside permissive project, missing/unknown license.
- Transitive — full tree; name the parent to bump for a transitive fix.
- Behavior — phone home? install scripts? unexpected egress?
2. Build / CI
- CI-only release builds?
- Actions pinned to commit SHA (not floating tag)?
- Lockfile committed + enforced in CI?
- Minimal token scope? No
pull_request_target?
3. Artifact
- SHA-256 checksums published for every binary?
- Signed (Authenticode/GPG)? Gap documented honestly?
- SBOM generated?
- User can verify before running?
Tooling
Per-ecosystem vuln/license/outdated commands + offline fallback: read references/tooling.md when selecting scanners.
Discipline
- Ground every CVE/fixed-version in an advisory. Never from memory.
- Don't auto-change deps — report + recommend; user decides (bumps break builds).
- State what was NOT scanned. Blocked network scans → lockfile inspection fallback (see
references/tooling.md), mark live checks N-A.
Fix mode (choice-gated)
After the report, present via ask_question:
- Pin safe now — commit already-present unchanged lockfile, pin CI action to current SHA, add missing checksum step. Each: checkpoint → apply → verify.
- Let me pick — user-selected fixes only.
- Report only — change nothing.
NEVER auto-fix: dep version bump, lockfile regen (re-resolves entire transitive tree).

Escalation — Scope & Model Quality
Tiers are capability targets, not platform commands — resolve each to your host's nearest lever. No lever for one? Degrade gracefully — never fake parallelism you can't do; escalate via model tier + reasoning depth instead.
| Level | Intent | Capability target | Cost |
|---|
| Light | Single-section check, spot audit | Cheapest model · single agent, no sub-agents. | Low |
| Standard | Multi-section balanced audit | Balanced model · raised reasoning · sub-agents per category only if your platform runs concurrent workers (else single-agent). | Balanced |
| Heavy | Full 3-section audit + adversarial CVE verify | Most capable model + largest context · deepest reasoning · max sub-agent fan-out if supported · adversarial cross-check where available. | High |
Per-platform Heavy levers + Heavy-run durability: read references/escalation.md before a Heavy run. No concurrent fan-out on your host → escalate by model + reasoning only.
Agent Context (interactive): score the tier rubric, then call ask_question once with the 3 tiers — the pick marked ✓, score shown, labels localized — and wait for the choice before starting. ask_question = your platform's question tool: Claude Code AskUserQuestion · Cline ask_question · Copilot askQuestions · Gemini CLI ask_user (business-tier product; individual tiers ended 2026-06-18 → Antigravity CLI) · Codex request_user_input · Cursor/Devin Desktop (ex-Windsurf)/Antigravity built-in prompts; none → numbered text menu.
Tier rubric (deterministic): +1 each — ① >20 files or whole-repo/cross-module reach ② >2 of this skill's categories relevant ③ release/security/pre-ship context ④ findings will drive code changes. 0–1 Light · 2–3 Standard · 4 Heavy. Freshness cap: scope already audited ≥Standard this session → cap at Light (re-auditing fresh ground wastes tokens; scope to what changed). Default tier: honor .coalmine.json defaultTier unless the user requests a tier for that run — an explicit request overrides everything.
Hook Context (auto-triggered): auto-Light, no tier question, no sub-agents — report first. Interactive session (a user is present) → offer the fix menu after the report; non-interactive → report-only. Never fix without a chosen option.
Entanglement: after the report, if confirmed findings fall in another canary's domain, offer it once via ask_question (one line, max one offer): perf/N+1 → scale-canary · contract/serialization/config → drift-canary · failure-path/retry → resilience-audit · logging/metrics → telemetry-canary · coupling/DI → testability-canary · dependency/CVE → supply-chain-audit · unverified version-sensitive claim → source-grounding · missing/stale rule → gold-standard.
Self error-report: if this skill misbehaves (contradictory instruction, broken procedure, wrong finding class), OFFER to file it at https://github.com/HetCreep/CoalMine/issues/new/choose with a user-reviewed summary — never auto-submit, never include unapproved code or paths.
