verify-security

verify-security is a skill for Claude Code from easyinplay/harnessed. It costs 106 tokens per session (1,362 once invoked), scanned A, original, Apache-2.0.

A conditional security-review workflow for the verification stage of software work. It checks authentication, credentials, secret handling, SQL-injection paths, and areas covered by OWASP, a widely used web-security guidance list.

In plain words
What is it for?
Use it to review login and session flows, API keys, credentials, secrets, and code paths that could allow common web attacks.
Why use it?
It adds a security check where sensitive code or data is involved, while skipping work such as documentation or purely visual changes.

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

verify-security 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 25d 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.

verify-security workflow (v3)

Overview

1-phase sub-workflow mapping CLAUDE.md "Verify 阶段 — 可选 /cso" onto harnessed runtime (Phase v3.0-3.4 W0.13b — D-04 Stage ④ Verify 7 sub + D-12 gstack 治理关卡 + Pattern A sub-workflow ship)。

phase id upstream model capability gate
1 01-cso gstack opus {{ capabilities.gstack-cso.cmd }} judgments.stage-routing.verify-security-secrets.fires

Per-phase config loads from workflows/verify/security/workflow.yaml; engine 4-level gate resolver evaluates phase.has_auth_or_secrets == true via expr-eval — true 则 invoke gstack /cso (OWASP / auth / credentials / secrets 全面审查), false 则 skip。

Capability refs

Sister workflows/capabilities.yaml entries:

  • gstack-cso — Bucket 3 治理关卡 (impl: gstack, cmd: /cso, fires_when: phase.stage == 'verify' AND phase.has_auth_or_secrets == true)

Gate ref

Sister workflows/judgments/stage-routing.yaml:

  • verify-security-secrets.fires — phase.stage == 'verify' and phase.has_auth_or_secrets == true

Routing rules

  • ✅ 触发: auth flow / session / credentials / API keys / SQL injection 路径 / OWASP top 10 area
  • ❌ 跳过: docs / 纯 UI styling / 内部 refactor / non-security PR

How to invoke

!harnessed checkpoint intent verify-security

The banner above (when present) means this invocation is REGISTERED with the engine (an intent marker) — not yet compliant: the steps below (prompt → spawn → checkpoint complete) resolve it, and a per-turn <workflow-intent> reminder persists until they run.

The numbered sequence below is the state machine — execute it with Bash. Do NOT improvise an equivalent flow from the Overview above: freelancing bypasses the engine (no ledger, no evidence guard). harnessed gives you the spawn-ready prompt; YOU spawn the subagent with a {{ host.native }} {{ host.spawn_subagent }} (keeps the session responsive + lets clarification round-trips reach the user).

Do NOT pipe to harnessed run verify-security — that is the CI/headless path ({{ host.harnessed_run_warning_note.execution_tail }}

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.
