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 5.1 | $0.00029 | $0.01062 |
| Opus 5 | $0.00015 | $0.00531 |
| Sonnet 5 | $0.00006 | $0.00212 |
| Haiku 4.5 | $0.00003 | $0.00106 |
Grade A, and why
verify-before-claim 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 8d 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.
This is a copy
86% identical to verify-before-claim — 15 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Verify Before Claim
<skill_contract> One falsifiable claim, its artifact or system, risk, expected result, permissions, and available checks. A scoped claim decision with fresh evidence, residual risk, approval, and rollback status. The cheapest direct check after the final material change supports the exact allowed wording. <non_goals>Producing the artifact, inferring success from effort, or widening a claim beyond checked evidence.</non_goals>
No evidence, no claim. Match the check to the exact claim, use fresh evidence, and keep execution authority separate from approval authority for consequential actions.
Usage Template
Provide: proposed claim, artifact or system, risk level, available checks, expected result, permissions, and rollback path.
Workflow
- Rewrite the proposed statement as one falsifiable claim.
- Classify risk: low, material, or consequential.
- Select the cheapest check that directly tests the claim.
- Record expected signal, time boundary, and acceptable evidence.
<unknowns_gate>
If the artifact, expected behavior, or verification method is missing, return NEEDS_INPUT. If only indirect evidence exists, return INSUFFICIENT_EVIDENCE or narrow the claim; never fill the gap with confidence language.
</unknowns_gate>
Run the selected check after the final material change. Examples: targeted test, lint, build, link check, read-after-write, diff inspection, source comparison, dashboard query, or deployment health check. Capture command/query, timestamp, scope, exit status, and key output.
For material or consequential claims, obtain independent verification from a separate check, reviewer, or evidence source. Require human approval before irreversible publication, deployment, spending, deletion, credential use, or policy change. Confirm the rollback path before execution.
For Graph claims, verify static contract integrity, every required node and join receipt, terminal acceptance, budgets, permission/compensation state, and checkpoint identity. Passing nodes do not prove the end-to-end graph.
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-before-claim is a skill published in the GitHub repository Mark393295827/graph-engineering-architectures (2 stars, last pushed 18d ago), licensed MIT. It adds 29 tokens to every session and 1,062 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 86% identical to verify-before-claim, differing in 15 lines, and is treated as a copy.
