god-harden

god-harden is a skill for Claude Code from hannsxpeter/godpowers. It costs 53 tokens per session (412 once invoked), scanned A, original, MIT.

A security review skill that checks an application against relevant OWASP Top 10 risks, dependencies, and committed secrets. OWASP Top 10 is a standard list of common web and software security risks.

In plain words
What is it for?
It is for checking trust boundaries, untrusted input, authentication, access control, injection, dependencies, and secrets, then fixing or recording findings.
Why use it?
It helps find exploitable problems and track unresolved risks before a public release.

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

god-harden 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 10d 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.

What it actually says

/god-harden

  1. Run the pass yourself, or delegate it to a subagent of your choice, run however you prefer. Either way it covers: the trust boundaries and where untrusted input enters; each OWASP Top 10 (2025) category that can apply to this product form (web app, API, CLI, library, or service), probed against a local build where possible; the dependency audit; committed secrets. A delegated auditor gets the product form, the entry points, and the verify command. Before you start it, say which model and effort you picked and why, then pass both explicitly (whichever your host accepts); never let it inherit yours. Size both to the stakes: the most capable model at high effort for products that handle auth, money, personal data, or internet-facing input; a faster model at lower effort for a small internal tool.
  2. Findings read severity: what, where, how to reproduce. Critical means exploitable now (data exposure, auth bypass, code execution). High is exploitable with effort, medium is a defense-in-depth gap, low is hygiene.
  3. Fix criticals and highs now, each with a regression test, then run npx -y godpowers@7 verify "<verify command>". List anything left open under Risks in STATE.md with its severity.
  4. Record the result on the final code: npx -y godpowers@7 record harden --pass --summary "<what was checked, counts by severity>". Use --fail while a critical is open.
  5. When no critical risk is open, set stage: ship in STATE.md if the user asked to ship, otherwise stage: done.

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.
