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.

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 | $0.00393 | $0.00393 |
| Opus 5 | $0.00197 | $0.00197 |
| Sonnet 5 | $0.00079 | $0.00079 |
| Haiku 4.5 | $0.00039 | $0.00039 |
Grade A, and why
verify 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 3d 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
Project
opslane-verify — a Claude Code plugin that verifies a change works. It turns the change's plan into acceptance criteria, stops for approval, then drives the real system and reports what it observed.
Architecture
skills/verify/SKILL.md the workflow. Claude is the control loop.
pipeline/ the engine. Three CLI verbs over three pure modules.
The skill decides what to check and judges the result. The engine only does plumbing that would be silly to do in markdown:
criteriarenders the approval artifact from JSONreportrenders the report from JSONchanged-fileslists behaviour-bearing changed files, and coverage gaps given claims
Run artifacts land in the target repository under .verify/runs/<id>/ and are gitignored
there. The engine holds no state.
Boundaries
The skill never fixes what it judges. It never derives acceptance criteria from the diff alone. It never reads source to decide pass or fail — a criterion that cannot be checked without reading code is the wrong criterion.
Skill sync
skills/ is the source of truth. A PostToolUse hook (.claude/hooks/sync-skill.sh)
copies the skill to ~/.claude/skills/ after every Write or Edit. Never edit the copy
under ~/.claude/ directly.
Note: an installed plugin resolves the engine through CLAUDE_PLUGIN_ROOT. Set
VERIFY_PIPELINE only when running from a development checkout.
Engine work
cd pipeline && npm ci
npm test # vitest
npm run typecheck # tsc --noEmit, expected clean
The three lib modules are pure functions over plain data. Keep them that way: everything
that touches the filesystem, git, or the network lives in cli.ts.
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.

verify CLAUDE.md is an instructions file published in the GitHub repository opslane/verify (115 stars, last pushed 27d ago), licensed MIT. It adds 393 tokens to every session, about $0.0020 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.
