Code Review Security

Vulnetix Code Review (Security) Skill

Use when

• Pre-merge: comprehensive security gate on the PR diff.
• Post all the right checks (SAST + SCA + secrets + container + IaC + license) without invoking each one separately.
• Producing a unified PR review comment via gh pr review.
• CI gate: block merge if any subsystem reports critical/high findings.
• Pre-release: final security pass on the release branch.

Don't use for

• Single-subsystem scan — use the specific skill (/vulnetix:sast-scan, etc.).
• Triage of existing memory state — use /vulnetix:dashboard.
• Multi-step orchestration with conflict resolution — use @pr-security-reviewer agent.

Conventions

This skill follows _lib/contract.md: the Vulnetix CLI is auto-installed by hooks, .vulnetix/capabilities.yaml is always present, every vulnetix vdb call is piped through a verified jq filter from _lib/jq/, independent calls run in parallel as concurrent Bash tool calls, and trailing follow-ups are limited to one line. See the contract for output style, memory write rules, and cooldowns.

A complete pre-merge security gate. Composes SAST + SCA + secrets + container + IaC + license, scoped to the diff.

Step 1: Load capabilities

Read .vulnetix/capabilities.yaml. Use repo.* flags to skip scanners that have nothing to scan (e.g. skip IaC if no *.tf present).

Step 2: Decide diff scope

If --pr <number> and binaries.gh: true:

gh pr diff "$PR" --name-only > .vulnetix/review/changed-files.txt

Else default to git diff --name-only "$BASE"...HEAD.

Step 3: Run scans (parallel)

PATHS=$(cat .vulnetix/review/changed-files.txt | tr '\n' ' ')

vulnetix scan \
  --evaluate-sast \
  --evaluate-secrets \
  --evaluate-sca \
  $( [[ "$has_iac" == "true" ]] && echo "--enable-iac" ) \
  $( [[ "$has_containers" == "true" ]] && echo "--enable-containers" ) \
  --paths "$PATHS" \
  -o json-sarif > .vulnetix/review/${TIMESTAMP}.sarif

Plus license check if direct deps changed:

vulnetix license -o json-spdx > .vulnetix/review/${TIMESTAMP}.licenses.spdx.json

Step 4: Render unified review

Sections:

• Summary: counts by severity across all surfaces
• Findings table (max 50 rows, ordered by severity)
• Suggested next actions (per finding type)

If --pr <number> and binaries.gh: true, optionally post the review:

gh pr review "$PR" --comment --body-file .vulnetix/review/${TIMESTAMP}.summary.md

Pause for user confirmation before posting.

Step 5: Verdict

Review verdict: APPROVE | REQUEST_CHANGES (N blockers)

Memory: append event: code-review-security with summary counts.

Edge cases & gotchas

• Six subsystems run in parallel — pace by 1s between batches if rate-limited.
• gh pr review posting requires binaries.gh: true AND a valid gh auth status. Pass --no-post to dry-run.
• Scope defaults to PR diff (gh pr diff --name-only); without --pr it falls back to git diff origin/main...HEAD.
• Empty subsystem (e.g. no Dockerfile changed) is skipped — does not contribute to the verdict.
• Dep-add-guard runs only on NEWLY ADDED direct deps in the diff; existing deps are not re-checked here.
• Verdict APPROVE / REQUEST_CHANGES is a recommendation — the user still drives the actual gh pr review --approve|--request-changes.
