Security
Audit Code
Audit code twice across five disciplines and produce one prioritized report with evidence, fixes, and checks.
What it does
Audits a repository, module, path, or PR diff in two passes across security, performance, UX, DX, and edge cases. It maps critical invariants across mutating routes, webhooks, jobs, and scripts, then reconciles specialist findings through a tie-breaker lead. The output is one severity-ordered report with evidence, assumptions, fixes, and verification checks.
When to use it
- Pre-merge audit of a PR diff
- Repository-wide security and performance review
- Cross-route invariant consistency check
- Residual-risk review after proposed fixes
The skill document
Audit Code
Overview
Run an expert-panel audit with strict sequencing and one unified output document. Produce findings first, sorted by severity, with file references, exploit/perf/flow impact, and actionable fixes.
Load references/audit-framework.md before starting the analysis.
Required Inputs
Collect or infer the following:
- Audit scope: paths, modules, PR diff, or whole repository.
- Product context: PRD/spec/user stories, trust boundaries, and critical business flows.
- Runtime context: deployment model, queue/cron/background jobs, traffic profile, data sensitivity, and abuse assumptions.
- Constraints: timeline, acceptable risk, and preferred remediation style.
If product context is missing, state assumptions explicitly and continue.
Team Roles
Use exactly these roles:
- Security expert
- Performance expert
- UX expert
- DX expert
- Edge case master
- Tie-breaker team lead
The tie-breaker lead resolves conflicts, prioritizes issues, and produces the final single report.
Workflow
Follow this sequence every time:
-
Build Context Read code + product flows. Identify assets, entry points, high-risk operations, privileged actions, external dependencies, and "failure hurts" journeys.
-
Build Invariant Coverage Matrix Before specialist pass 1, map critical invariants to every mutating path (HTTP routes, webhooks, async jobs, scripts):
- Data-link invariants: multi-table relationships that must remain consistent.
- Auth lifecycle invariants: disable/revoke semantics for sessions/tokens/API keys.
- Input/transport invariants: validation, content-type policy, body-size/parse behavior.
- Shape invariants: trees/graphs must reject cycles where applicable. Treat missing parity across equivalent paths as a finding candidate.
- Pass 1 Specialist Reviews Run role-specific analysis in this order:
- Security
- Performance
- UX
- DX
- Edge case master
Capture findings using the schema in
references/audit-framework.md.
- Tie-Breaker Reconciliation Resolve disagreements:
- Decide whether contested items are true issues.
- Set severity and confidence.
- Remove duplicates and merge overlapping findings.
- Cross-Review Pass 2 After edge-case findings, rerun specialists:
- Security/Performance/UX/DX reassess prior findings and new edge-triggered scenarios.
- Edge case master performs a final pass on residual risk after proposed mitigations.
- Final Report Publish one document from the tie-breaker lead with:
- Findings first (ordered by severity, then blast radius, then exploitability).
- Open questions/assumptions.
- Remediation plan with priority, owner type, and verification tests.
- Short executive summary at the end.
Quality Bar
Enforce these requirements:
- Use concrete evidence with file references and line numbers where available.
- Include reproduction steps for security/performance/edge findings when feasible.
- Prefer actionable fixes over abstract advice.
- Separate confirmed defects from speculative risks.
- Mark confidence for each finding.
- Run a cross-route consistency sweep: equivalent endpoints/jobs must enforce equivalent invariants.
- For each High/Critical finding, include at least one focused regression test/check.
Safety and Policy Guardrails
Apply these guardrails while auditing:
- Do not provide operational abuse instructions or exploit weaponization details.
- Evaluate manipulative UX patterns as legal/trust/reputation risk, not as recommended growth tactics.
- Prioritize user safety, system integrity, and maintainable engineering outcomes.
Output Format
Follow this response structure:
-
Findings List only validated issues. Use the finding schema in
references/audit-framework.md. -
Open Questions / Assumptions State missing context that could change priority or validity.
-
Change Summary Summarize high-impact remediation themes in a few lines.
-
Suggested Verification List focused tests/checks to confirm each major fix.
Runtime Heuristics
When the target stack is Bun + SQLite, apply the runtime-specific checklist in references/audit-framework.md (Runtime-Specific Heuristics (Bun + SQLite)) before finalizing findings.
Questions people ask
- What context does the audit need?
- It collects or infers the audit scope, product flows and trust boundaries, runtime and deployment details, data sensitivity, abuse assumptions, timeline, risk tolerance, and remediation preferences. If product context is missing, assumptions are stated explicitly before continuing.
- How are duplicate or disputed findings handled?
- A tie-breaker lead decides whether contested items are valid, assigns severity and confidence, removes duplicates, and merges overlapping findings. Specialists then reassess findings in a second cross-review pass.
- What does the final report contain?
- The report lists validated findings first, followed by open questions and assumptions, a change summary, and suggested verification. Findings use file and line references where available, actionable fixes, and focused regression checks for every High or Critical issue.
