Receipted Operator
A free Claude Code plugin that verifies AI agent work: receipts, a truthful status set, and an independent verifier that returns FALSE_DONE when an agent claims a task is complete and the artifact isn't there.
For anyone running AI agents who has been burned by green checkmarks that checked nothing.
What it gives you
- A decision doctrine: default-go rules, hard gates, and two permanent lines (email and money never automate).
- A truthful status set:
PROPOSED → AWAITING_APPROVAL → QUEUED → RUNNING → COMPLETED → VERIFIED, plus FAILED, BLOCKED_INFRASTRUCTURE, UNVERIFIED. Never DONE without a receipt.
- A receipt ledger shape you can drop into Notion, a spreadsheet, or a folder.
- An independent verifier (
verify/verify.py, standard library only) that checks claimed artifacts against a manifest and returns FALSE_DONE when a completion claim has nothing behind it.
- A brief template that forces an observable outcome and a demonstrated-failure done-test.
Install (Claude Code)
/plugin marketplace add datumline/receipted-operator
/plugin install receipted-operator@datumline
Skills
/receipt – write a receipt in the ledger shape for the work just done./verify – run the verifier against a manifest and report VERIFIED / FAILED / FALSE_DONE./brief – turn a request into an outcome-plus-falsification brief./session-open – write a timestamped, attributed session record before new work.
The one rule this plugin is built on: the thing that audits the work must not share code, process, or state with the thing that did the work. verify/verify.py imports nothing from your runtime. That is why it can call your runtime a liar.
Proof it works (do this once): mark any job COMPLETED with no artifact, run /verify. You should see FALSE_DONE. If you see green, the plugin is broken and you should not trust it.
Not a security audit. Not a compliance certification. A tool you run on your own work. Composes with cryptographic tool-call receipts (e.g. protect-mcp) which sign that a call happened; this verifies that the job produced its artifact.
Going further
- Receipted Operator Pro: this plugin plus Audit Trail and the Governance Gate Kit, which are not in this repository.
- Datumline methods: working kits for agent governance, audit trails, decomposition, decorrelated ideation, deal assessment, portfolio estimates and real-estate calculations. Every kit ships scripts whose tests fail when the method is broken.
