verification

verification is a skill for Claude Code from TechDufus/oh-my-claude. It costs 60 tokens per session (974 once invoked), scanned A, original, MIT.

A method for checking work with current evidence before saying it is complete. It requires identifying each claim, running the relevant tests or builds, and reading their results.

In plain words
What is it for?
It is for verifying tests, builds, linters, feature behavior, and readiness before committing, opening a pull request, or handing work to someone else.
Why use it?
It prevents completion claims based only on assumptions or old test results. The method makes failures, warnings, and regressions easier to catch before handoff.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.
    Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.

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

verification 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.

Verification Skill

No evidence, no completion claim. Period.

The Iron Law

NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE

"I think it works" is not evidence. "Tests passed 5 minutes ago" is not fresh. Run the checks NOW, read the output NOW, then claim completion.

When to Apply

  • About to say "done", "complete", or "ready"
  • Before committing or creating a PR
  • After agent teammates claim work is finished
  • When the verification_reminder hook fires
  • Before any handoff to another person or system

Gate Function

IDENTIFY

What needs verification? List every claim you're about to make.

  • Tests pass? Which test suite?
  • Build succeeds? Which build command?
  • Feature works? What specific behavior?
  • No regressions? What could have broken?

RUN

Execute the actual checks. Not "I think they pass" - run them NOW.

  • Run the test suite. Capture output.
  • Run the build. Capture output.
  • Run linters if applicable. Capture output.

READ

Read the output. Actually read it. Don't assume.

  • Check exit codes (0 = success, anything else = failure)
  • Look for warnings that might indicate issues
  • Count passing vs failing tests
  • Verify the output matches expectations

VERIFY

Does the output confirm success? Cross-reference against requirements.

  • Every requirement has corresponding evidence
  • No skipped tests that cover changed behavior
  • No warnings that indicate degraded functionality

CLAIM

Only now can you claim completion. Include the evidence.

Common Failures

Claim Requires Not Sufficient
"Tests pass" Fresh test run output "They passed before"
"Build succeeds" Actual build output "It should build"
"Feature works" Demonstrated behavior "I implemented it correctly"
"No regressions" Full test suite run "I only changed one file"
"PR is ready" All checks green "I think it's good"
"Bug is fixed" Reproduction test passes "I addressed the cause"

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.
