Verify agent completion claims against git ground truth
Skill that checks an agent's done or shipped claim against git ancestry and the real commit diff using the deterministic DOS kernel.
19.0.1Add to Favorites
Why it matters
Ensure AI agent claims of "done," "shipped," or "fixed" are factually grounded by validating them against actual git commit history and diffs using the deterministic DOS kernel, replacing unreliable self-reports with witness-based verification.
Outcomes
What it gets done
Shell the DOS kernel to verify claimed changes against git ancestry
Audit commit diffs to confirm the agent's stated effects actually occurred
Replace agent self-consistency checks with external ground-truth validation
Run offline, deterministic git-only verification without LLM or API calls

Overview
A skill that replaces an agent's self-report with a deterministic verdict from the DOS kernel, based on git ancestry and the commit's actual diff. Use when an agent claims something is done and you want independent evidence. Verdicts are git-only and offline unless a CI oracle is wired.
What it does
Verify done-claims against ground truth is a skill built on one idea: when an AI agent says done, shipped or fixed, that is a claim and not a fact. A claim the agent checks by re-reading its own work is consistency, not grounding. This skill replaces that self-report with a verdict from a witness the agent did not author.
To do this it calls the DOS kernel through two commands, dos verify and dos commit-audit. They confirm the claimed effect from git ancestry and from the commit's actual diff. DOS is described as deterministic, needing no API key and no LLM, so the verdict does not depend on another model's opinion.
When to use - and when NOT to
Use it whenever an agent reports that work is complete and you want independent evidence before accepting the report, for example after an agent says a fix has shipped and you need to know whether the claimed commit and diff really contain it.
Note the limits. As used here the verdict is git-only and offline. The single exception is dos verify in a workspace that wires a CI oracle, where the check can reach beyond git; the no-ci flag suppresses that behavior. Its Security and Safety Notes cover the details of the CI path.
Inputs and outputs
The inputs are the agent's claim of completion and a git repository containing the commit or change it refers to. The output is a verdict on whether the claimed effect is confirmed by the repository's history and the commit's real diff, produced by the DOS kernel instead of by the agent.
Who it's for
Engineers and teams who use AI coding agents and want completion claims checked against commit history rather than taken on trust.
Source README
When an AI agent says "done", "shipped", or "fixed", that is a claim, not a
fact - and a claim the agent checks by re-reading its own work is consistency,
not grounding. This skill replaces that self-report with a verdict from a
witness the agent did not author: it shells the DOS kernel (dos verify,
dos commit-audit) to confirm the claimed effect from git ancestry and the
commit's actual diff. DOS is deterministic - no API key, no LLM. The verdict is
git-only and offline as used here; the one exception is dos verify in a
workspace that wires a CI oracle, which --no-ci suppresses (see Security &
Safety Notes).
