pi-papercuts

Agent files one-line friction notes into .papercuts.jsonl and keeps working. Review the backlog later.

Port of treygoff24/papercuts (MIT) for Pi. Pure Node. Needs Pi + Node 22+.

Install

pi install npm:pi-papercuts

From a clone of this monorepo:

pi install ./packages/pi-papercuts

Use

papercuts({ action: "add", text: "what broke + what would have prevented it", tags: ["tooling"], severity: "major" })
papercuts({ action: "list" })
papercuts({ action: "list", format: "md" })
papercuts({ action: "resolve", ids: ["pc_9f2c"], note: "fixed" })
papercuts({ action: "doctor" })
papercuts({ action: "schema" })

| Action | What it does | |--------|----------------| | add | File a cut (text required). Optional tags, severity. Evidence is free-note or cmd/exit/stderr, not both. Wire alias log → add. | | list | Open cuts by default. Filters: status, agent, tag, severity, limit, format (json | md). | | resolve | Mark ids resolved (pc_ + ≥4 hex). Append-only. | | doctor | Validate the log. | | schema | Machine contract for agents. |

Severity: minor (default), major, blocker. Ids are content-addressed; duplicate adds are no-ops.

Interactive Pi uses a compact themed call/result view. Expand a tool row for the full text, tags, and log path. Structured result details remain available to the agent and session history.

Where it stores

1. file param
2. PAPERCUTS_FILE
3. nearest .git → <root>/.papercuts.jsonl
4. else ~/.papercuts/log.jsonl

Optional: PAPERCUTS_AGENT, PAPERCUTS_NOW (tests).

echo .papercuts.jsonl >> .gitignore   # keep local only

With pi-deferred-context-engine, defaults pin papercuts so it stays active.

Gotchas

• Does not auto-detect failures -- the agent has to call it (habit / AGENTS.md).
• Not a secret store. Size caps only; resolve does not erase cut text.
• Outside git, log goes under home unless PAPERCUTS_FILE is set.
• Log path must be a normal file (not a directory, FIFO, or device).

More: residual risks.
