verify-completion

verify-completion is a skill for Claude Code, Codex from KhaledSaeed18/dotclaude. It costs 69 tokens per session (708 once invoked), scanned A, original, MIT.

A checking rule that requires fresh command output before saying that work is complete, fixed, or passing. It treats claims about software status as statements that need evidence.

In plain words
What is it for?
Use it before committing, opening a pull request, handing off work, or reporting that tests and fixes succeeded.
Why use it?
It prevents unverified success claims by requiring the actual test or verification command to be run and its full result to be read.

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-completion 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Don't claim work is done, fixed, or passing unless you've just run the thing that proves it and read the output. Saying it's complete when you haven't checked isn't optimism — it's reporting something you don't know to be true, and it breaks trust the moment it turns out wrong.

The one rule

No completion claim without fresh verification. If you haven't run the verifying command in this turn, you can't say it passes. "Should pass now", "I'm confident", "the logs looked fine" are not evidence — they're the feelings that precede unverified claims.

The gate

Before stating any status, or even expressing satisfaction ("great", "perfect", "done"):

  1. Identify the command that would prove the claim.
  2. Run it — the full command, fresh, start to finish. Not a partial check, not a remembered result from earlier.
  3. Read the whole output: exit code, failure count, warnings.
  4. Decide. Does the output actually confirm the claim? If not, state the real status with the evidence. If so, state the claim with the evidence.

Skipping any of these steps turns a verification into a guess.

What each claim actually requires

Claim What proves it What does not
Tests pass A fresh test run showing 0 failures A previous run; "should pass"
Linter clean Linter output, 0 errors A partial check; extrapolating
Build succeeds Build command, exit 0 Linter passing; logs "looking good"
Bug fixed The original symptom retested and gone The code changed, so it's "probably fixed"
Regression test works Watched it fail before the fix, pass after It passes once now
Requirements met A line-by-line pass over the requirements Tests passing
Subagent finished The actual diff / output inspected The subagent reporting "success"

A linter passing doesn't mean it compiles. A subagent saying "done" doesn't mean it did the work — check the diff. A regression test that's only ever passed hasn't been shown to catch anything; verify it fails without the fix, then passes with it.

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-completion is a skill published in the GitHub repository KhaledSaeed18/dotclaude (5 stars, last pushed 2d ago), licensed MIT. It adds 69 tokens to every session and 708 once invoked, about $0.0003 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 2026-08-31.
