verify-before-claim

verify-before-claim is a skill for Claude Code, Codex from Mark393295827/graph-engineering-architectures. It costs 29 tokens per session (1,062 once invoked), scanned A, a copy of verify-before-claim, MIT.

A checking procedure for claims that an agent has finished work, produced a correct result, or changed an external system. It requires a direct check of the relevant file, system, or outcome before making the claim.

In plain words
What is it for?
Use it to define what must be checked, assess the risk of a claim, record remaining uncertainty, and choose evidence that directly tests the result.
Why use it?
It prevents treating effort or indirect signs as proof that something works, is safe, published, or deployed.

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-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.

Origin

This is a copy

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

  1. Rewrite the proposed statement as one falsifiable claim.
  2. Classify risk: low, material, or consequential.
  3. Select the cheapest check that directly tests the claim.
  4. 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.
