Security Auditor

You perform a comprehensive security audit covering dependency analysis through code review. Output is a prioritized security report with a concrete remediation plan.

Input: Codebase (src/), dependencies, configuration. Output: _devprocess/analysis/AUDIT-{PROJECT}-{YYYY-MM-DD}.md.

See skills/project-conventions/SKILL.md#canonical-specs (Writing style) and (Frontmatter spec). Both apply to every artifact this skill produces.

Pre-Phase 0: Branch and item check

Two modes:

• Per-item audit (inside /coding or before merging a feature): runs on the item's branch. sec-done tag goes on the same branch.
• Periodic full-codebase audit: runs on feature/audit-<YYYY-MM-DD>, produces a standalone AUDIT report, queues FIX/IMP follow-ups. No draft PR for the audit branch; follow-ups get their own branches via /coding.

Per-item audit: identify the active item, verify branch matches, then run flow.py create-issue and flow.py open-draft-pr (idempotent). At the Handoff Ritual end, run flow.py tag-phase --item <ID> --phase sec.

Full rules: skills/project-conventions/references/team-workflow.md.

Scope

In scope: SAST (CWE-based), OWASP Top 10, OWASP LLM Top 10 (when AI/LLM is present), SCA (dependencies, licenses), Zero Trust (trust boundaries, input validation), code quality security patterns.

Out of scope: penetration testing, compliance certification, architecture design (done by /architecture).

Audit Phases

Finding format (binding)

Each finding caps at five fields. Code diff only when the fix is not obvious from the remediation sentence.

H-N: <title>
- Severity: Critical | High | Medium | Low | Info
- CWE-ID:   CWE-XXX
- Location: <file:line>
- Risk:     <one sentence>
- Remediation: <one sentence with concrete action>

Status values: Confirmed, Mitigated, False Positive, Resolved. State the status, never leave a false positive silent. Consider context (DevDependency vs. Runtime).

Positive findings: up to 3 entries, skip entirely when overall risk is High or Critical. The team needs the negative list, not encouragement.

Severity schema: Critical (immediately exploitable, data loss / RCE), High (exploitable with low effort, significant impact), Medium (exploitable under specific conditions), Low (best-practice improvement), Info (note, no direct threat).

Audit summary block (canonical, define once)

Defined here. Do not restate the block in re-audit output or in the Handoff Ritual entry; reference the report instead.

=== Security Audit Result ===

Overall risk: {Critical / High / Medium / Low}

P1 (Must Fix, Critical + High): {N} findings
- {H-1}: {title}, {file:line}, effort {S/M/L}

P2 (Should Fix, Medium): {N} findings
- {M-1}: {title}, {file:line}, effort {S/M/L}

P3 (Consider, Low + Info): {N} findings
- {L-1}: {title}, effort {S/M/L}

Positive findings: {up to 3, omitted when overall risk High or Critical}

When to run

Before every release, after significant security-relevant changes, periodically (monthly for active projects), after dependency updates (SCA phase).

Create the report

Read templates/AUDIT-TEMPLATE.md, fill it, save to _devprocess/analysis/AUDIT-{PROJECT}-{YYYY-MM-DD}.md.

Fix-Loop

After the audit, the user picks scope.

Step 1: Show the summary

Render the audit summary block defined above. Once.

Step 2: Ask the user

How should I handle the findings?

A) Fix all findings (P1 + P2 + P3), then re-audit.
B) Fix only P1, defer P2/P3 to backlog.
C) Approve fixes one by one.
D) Nothing to fix, report only. All findings go to backlog.

Step 3: Fix implementation

For each finding to be fixed: implement the concrete remediation, run affected tests (no regressions), flip status Confirmed -> Resolved in the report. On Option C: show each fix before continuing.

Step 4: Re-audit (automatic)

Re-run affected audit phases. Report deltas only:

=== Re-Audit Delta ===

Before: {N} P1, {N} P2, {N} P3
After:  {N} P1, {N} P2, {N} P3
Resolved: {list}
New: {if a fix introduced new findings}

Loop until all in-scope findings resolve or the user aborts. Do not re-render the full summary block.

Step 5: Deferred findings -> Backlog

Each open finding becomes a row in _devprocess/context/BACKLOG.md per skills/requirements-engineering/templates/BACKLOG-TEMPLATE.md. Place under Standalone Items with: Typ = Security, Source = SEC, priority from severity (H -> P1, M -> P2, L -> P3), Status = Ready, Evidence = path:line, Notes = <H/M/L-ID> + short risk. Refresh dashboard counts. Audit report keeps status Confirmed with note "Deferred to backlog".

Step 6: Update artifacts

Audit report (final version), feature specs (security-relevant changes), ADRs (when fixes affect decisions), backlog (open findings).

Step 7: Run /consistency-check mode A

Catches deferred findings without backlog rows, FIX rows missing feature:/epic: frontmatter, drifted dashboard counts, dead links.

Handoff Ritual

Part 1: Artifact report

Produced / updated:
- _devprocess/analysis/AUDIT-{PROJECT}-{DATE}.md
- Findings resolved: {N}
- Findings deferred: {N}
- _devprocess/context/BACKLOG.md: deferred rows added

Part 2: Handoff context

Append a new entry to _devprocess/context/HANDOFFS.md. Reference the audit summary block by file path; do not restate it. Add:

• Unresolved P0/P1: open high-severity findings and why.
• Architectural concerns: patterns for a future /architecture cycle (trust-boundary issues that need redesign, not patching).
• Release recommendation: green / yellow / red verdict.

Part 3: Phase-end commit

Per skills/project-conventions/references/team-workflow.md section "Phase-end commit (binding)". Canonical message:

chore(audit): <ITEM-ID> audit complete

<one-line: risk verdict, N findings (P1/P2/P3), release recommendation>

Refs: <ITEM-ID>[, FIX-..., FIX-...]

After the commit:

python3 tools/github-integration/flow.py tag-phase --item <ID> --phase sec
python3 tools/github-integration/flow.py sync-status --item <ID>

sync-status mirrors BACKLOG Status to the GitHub issue and project (and Assignee back into Claim). No-op outside mode = "github-sync". Skip the commit silently if the working tree has no changes.

Part 4: Transition

"Security audit complete. Report: _devprocess/analysis/AUDIT-{PROJECT}-{DATE}.md. Release readiness: {green/yellow/red}. Recommended next: /consistency-check mode B finalises the artifact graph and returns a Release-Ready verdict. Run /consistency-check mode B now, or review the audit first?"

On agreement (or when running inside /dia-guide): run /consistency-check mode B; on Release-Ready: yes the /dia-guide Closing Handoff fires. On rejection: pause.
