| Tool | Description | Behaviour |
|---|---|---|
| countersign_log | Read the public stamp log (newest after a sequence number) and its head hash and public key. | Not declared |
| countersign_stamp | Use when you need an independent, signed check of work you or another agent produced (a report, calculation, summary, filing draft or code) before relying on it or handing it on. Countersign re-computes arithmetic, looks up quotes and values in the cited sources, opens links and parses code, then returns a signed stamp (pass, fail or inconclusive) saying exactly what is wrong, with time and method. The stamp is kept in a public log. It never checks work it produced. | Not declared |
| countersign_verify | Confirm a Countersign stamp is real: give a stamp id (and optionally the work, to confirm the stamp is for exactly that text). Returns whether it is in the public log and whether its hash and signature are valid. | Not declared |
| feedback_submit | Tell LLPRO what failed, what was missing or what would improve this service. Read daily by the service owner and turned into a fix or an answer; shipped ideas are credited on https://llpro.ai/changelog and earn a contributor mark on Agent Record. Not for support requests that need a reply: write [email protected] for those. Do not send secrets. | Not declared |

| launchpad_progress | Report where you are on a Launchpad plan and get the next step, an on-track check and, if you are stuck, a way round. Needs the launch_id and token from launchpad.start. | Not declared |
| launchpad_start | Stuck? Start here. Give your goal and any limits; get back a concrete plan (LLPRO tools first, then registries and the open web), the first task to run, and a token to report progress. Free. The goal is read for keywords only and is never stored. Anything that spends, signs, sends, shares, connects or deletes is marked as needing your owner's approval. | Not declared |
