Repository instructions for StackHawk Agent Skills, a collection that teaches coding agents to run web-application security scans and query the StackHawk service.

In plain words
What is it for?
Use it when editing, generating, validating, or maintaining the repository's HawkScan, StackHawk API, and related agent skills.
Why use it?
It explains the repository layout, which files are generated, and how to verify that skill generation is repeatable without unintended changes.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agent-skills CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

StackHawk Agent Skills

Multi-platform agent skills repo serving Claude, Codex, Gemini, Copilot, Cursor, and OpenCode from one canonical source. Skills teach AI agents to run HawkScan DAST security scanning and query the StackHawk platform API.

Structure

  • plugins/hawkscan/ — HawkScan DAST scanning skill (SKILL.md + references + hooks)
  • plugins/api/ — StackHawk API reporting skill (SKILL.md + references)
  • plugins/wingman/ — Umbrella plugin; /plugin install wingman@stackhawk installs hawkscan + api + data-seed + optimize
  • plugins/wingman/copilot-skills/ — Generated copies of wingman's four skills for GitHub Copilot (do NOT edit)
  • .claude/skills/skill-authoring/ — Maintainer skill: authoring rules and best practices for contributors to this repo (NOT distributed via marketplace; tracked in git via .gitignore negation)
  • skills/ — Symlinks for Gemini/Copilot discovery (points into plugins/)
  • .opencode/skills/ — Symlinks for OpenCode discovery (points into plugins/)
  • .cursor/skills/ — Symlinks for Cursor native skills discovery (points into plugins/)
  • plugins/hawkscan/hooks/cursor/ — Cursor hook scripts and hooks.json
  • cursor/ — Generated Cursor .mdc rules (do NOT edit manually)
  • scripts/generate-cursor-rules.sh — Transforms SKILL.md → Cursor .mdc format
  • scripts/bump-version.sh — Updates all version-bearing files atomically (reads .version-bump.json)
  • scripts/release.sh — Pre-release checks, creates tag, creates GH Release

Commands

# Regenerate Cursor rules after editing any SKILL.md or references/*.md
bash scripts/generate-cursor-rules.sh

# Verify generation is idempotent (no diff = correct)
bash scripts/generate-cursor-rules.sh && git diff cursor/

# Bump version (updates VERSION + all manifests + SKILL.md frontmatter in one pass)
bash scripts/bump-version.sh --patch   # bug fixes
bash scripts/bump-version.sh --minor   # new skill or significant capability
bash scripts/bump-version.sh --major   # breaking changes

# Release (validates manifests, Cursor rules, and the wingman Copilot bundle;
# creates annotated tag, creates GH Release)
bash scripts/release.sh --dry-run  # validate without creating anything
bash scripts/release.sh            # create tag + GH Release (must be on main, clean tree)

# macOS/Linux install
bash scripts/install.sh --platform cursor  --target ~
bash scripts/install.sh --platform copilot --target ~

# Regenerate the wingman Copilot bundle after editing any bundled SKILL.md
bash scripts/generate-wingman-skills.sh

# Validate the bundle
bash scripts/test-wingman-skills.sh

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
