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.
npx agentmods add rules/stackhawk/agent-skills/stackhawk-hawkscangit clone --depth 1 https://github.com/stackhawk/agent-skillsWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.06655 | $0.06655 |
| Opus 5 | $0.03327 | $0.03327 |
| Sonnet 5 | $0.01331 | $0.01331 |
| Haiku 4.5 | $0.00666 | $0.00666 |
Grade A, and why
stackhawk-hawkscan 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.
How it starts
The opening of the file, as written. The whole thing — 500 lines — stays where its author put it; the contents beside it link to each section on GitHub.
HawkScan Skill
This skill enables Claude to act as the security testing orchestrator in an agentic coding loop. The core workflow is:
Code changes → Start Application/API → Configure HawkScan → Run scan → Parse findings → Generate fix tasks → Repeat
Prerequisites (preflight — run before anything else)
This skill requires hawk v6.0.0 or newer. Verify:
hawk version
hawk config --help >/dev/null 2>&1 || echo "MISSING: hawk config — upgrade hawk to v6.0.0+"
hawk skills status
If hawk is older than 6.0.0 or hawk config --help fails, stop and tell the user to
upgrade before proceeding. Do not inline auth recipes from memory — they live in
hawk config show and are stale by design when hardcoded.
hawk skills status reports whether the installed StackHawk agent skills are current.
If it lists anything out of date, surface the exact upgrade command it prints (e.g.
/plugin marketplace update stackhawk && /plugin update hawkscan) and recommend the user
update before continuing — a stale skill may be missing fixes for the very issues you'll hit.
It's a recommendation, not a hard stop: proceed if the user prefers. (If the subcommand isn't
recognized, the installed hawk predates it — skip this check.)
See references/installation.md for upgrade and install instructions.
Companion Skills
The api skill wraps read-only StackHawk platform lookups via the hawk CLI (hawk op …):
| Purpose | Command |
|---|---|
| Check if App exists | hawk op app list --format json |
| Check if Env exists | hawk op env list --app <NAME|UUID> --format json |
| Get findings with triage | hawk op scan get --app <NAME|UUID> --detail full --format json |
| List ASM repos | hawk op repo list --format json |
| Link app to ASM repo | hawk op repo link --repo-id <ID> --app-id <ID> |
| Get tech flags | hawk op app tech-flags get --app <NAME|UUID> --format json |
| Disable all tech flags | hawk op app tech-flags disable-all --app <NAME|UUID> --yes |
| Set specific tech flags | hawk op app tech-flags set --app <NAME|UUID> Key=true |
| Triage a finding | hawk op scan triage --scan <ID> --hash <HASH> --status false-positive --note "" |
| Bulk triage from file | hawk op scan triage --scan <ID> --from-file triage.yaml |
| Annotate w/o triage perm | hawk op finding note --scan <ID> --hash <HASH> --note "..." |
| Get scanned URIs | hawk op scan uris <scanId> --format json (skip if the subcommand errors) |
| Get effective scan config | hawk op scan config <scanId> (skip if the subcommand errors) |
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.

stackhawk-hawkscan is a cursor rule published in the GitHub repository stackhawk/agent-skills (15 stars, last pushed 11d ago), licensed MIT. It adds 6,655 tokens to every session, about $0.0333 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
