## What blotter does, in the publisher's words

Your agents have complaints. Give them somewhere to write them down.

A tiny Rust CLI that gives AI agents a blotter, the pad on the desk where you note the thing before it's gone. Nothing on it is a commit, a ticket, or a chat message. Agents jot three kinds of records into one append-only journal:

- Cuts: friction worth keeping. A dead-end tool call, a broken link, a misleading error, a footgun config. Filed at the moment it happens, with optional evidence (the failed command, its exit code, its stderr).
- Dogears: findings. Something an agent noticed that is interesting beyond the task: a surprising measurement, an engineering quirk, a gap in prior art. A dogear is the page-corner you fold to come back to; here it marks a lead worth writing up in public.

## Skills

- blotter: Capture and review coding-agent friction, tool failures, workflow footguns, surprising findings, and durable learnings in a local append-only ledger. Use when an AI coding agent hits recurring, consequential, misleading, systemic, or transferable developer-experience problems; when running agent re…
