commit-security-scan: Security & Code Review for AI Agents | OpenAgentSkill

Overview

Scan code changes for security vulnerabilities using Bug Hunter-native artifacts and STRIDE context. Use whenever the user asks for PR security review, commit-diff scanning, staged-change security checks, branch-comparison security review, or pre-merge security analysis of changed code.

Source documentation, not instructions for this website. Review permissions before running any commands.

Commit Security Scan

This is a bundled local Bug Hunter companion skill. It is portable and self-contained: use .bug-hunter/* artifacts, never .factory/* paths.

Purpose

Review changed code for security issues only. This skill is optimized for:

PR review
staged diff review
branch diff review
commit / commit-range security scanning

Inputs

Resolve the scan scope from the user request:

PR review → use scripts/pr-scope.cjs
staged review → use git diff --cached --name-only
branch diff → use git diff --name-only <base>...<head>
commit range → use git diff --name-only <base>..<head>

Workflow

Ensure threat-model context exists.
- Preferred artifacts:
  - .bug-hunter/threat-model.md
  - .bug-hunter/security-config.json
- If missing, run the bundled threat-model-generation skill first.
Resolve the changed-file scope.
Read the full contents of the changed source files, not just the patch.
Focus on STRIDE-oriented issues in changed code:
- Spoofing: auth/session/token mistakes
- Tampering: SQLi, XSS, path traversal, command injection, mass assignment
- Repudiation: security-sensitive actions with no auditability
- Information Disclosure: IDOR, secret exposure, verbose errors
- DoS: unbounded input, missing limits, expensive regex/queries
- Elevation of Privilege: missing authorization, role bypass, privilege escalation
Reuse Bug Hunter-native security conventions:
- findings should be compatible with .bug-hunter/hunter-findings.json
- use STRIDE + CWE labels
- include confidence scores
If the user wants only a focused security diff review, stop after the findings report. If the user wants deeper validation, hand off to the bundled vulnerability-validation skill.

Output

Preferred outputs:

.bug-hunter/hunter-findings.json when integrating with the main Bug Hunter pipeline
.bug-hunter/report.md as a rendered companion if needed

Notes

This skill is intentionally diff-scoped; it does not replace full-repository audits.
Use it as the lightweight security fast-path before invoking the broader security-review flow.

# Commit Security Scan

This is a bundled local Bug Hunter companion skill. It is portable and self-contained: use `.bug-hunter/*` artifacts, never `.factory/*` paths.

## Purpose

Review *changed code* for security issues only. This skill is optimized for:
- PR review
- staged diff review
- branch diff review
- commit / commit-range security scanning

## Inputs

Resolve the scan scope from the user request:
- PR review → use `scripts/pr-scope.cjs`
- staged review → use `git diff --cached --name-only`
- branch diff → use `git diff --name-only <base>...<head>`
- commit range → use `git diff --name-only <base>..<head>`

## Workflow

1. Ensure threat-model context exists.
- Preferred artifacts:
- `.bug-hunter/threat-model.md`
- `.bug-hunter/security-config.json`
- If missing, run the bundled `threat-model-generation` skill first.

2. Resolve the changed-file scope.

3. Read the full contents of the changed source files, not just the patch.

4. Focus on STRIDE-oriented issues in changed code:
- Spoofing: auth/session/token mistakes
- Tampering: SQLi, XSS, path traversal, command injection, mass assignment
- Repudiation: security-sensitive actions with no auditability
- Information Disclosure: IDOR, secret exposure, verbose errors
- DoS: unbounded input, missing limits, expensive regex/queries
- Elevation of Privilege: missing authorization, role bypass, privilege escalation

5. Reuse Bug Hunter-native security conventions:
- findings should be compatible with `.bug-hunter/hunter-findings.json`
- use STRIDE + CWE labels
- include confidence scores

6. If the user wants only a focused security diff review, stop after the findings report.
If the user wants deeper validation, hand off to the bundled `vulnerability-validation` skill.

## Output

Preferred outputs:
- `.bug-hunter/hunter-findings.json` when integrating with the main Bug Hunter pipeline
- `.bug-hunter/report.md` as a rendered companion if needed

## Notes

- This skill is intentionally diff-scoped; it does not replace full-repository audits.
- Use it as the lightweight security fast-path before invoking the broader `security-review` flow.

Review the source

Skill source recorded

Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.

Review before install: Avoid automatic install

Permission surface may require sandboxing
Quality score needs review

Open full audit

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
