scratchboard

scratchboard is a skill for Claude Code, Codex from darecstowell/scratchboard. It costs 81 tokens per session (1,396 once invoked), scanned A, original, MIT.

A repair guide for Scratchboard, a read-only kanban board that displays work tickets from Markdown files. It explains how to configure the board and which ticket field an agent must edit to move a card between lanes.

In plain words
What is it for?
Use it to create or repair Scratchboard's configuration and parser, understand lane labels, or move a ticket by writing the repository's existing status value into the ticket.
Why use it?
It fixes cases where tickets are missing, appear in the wrong lane, or cannot be read because their format is unclear. It also keeps the board from modifying tickets itself.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

scratchboard scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Detection finds the tickets, picks a preset, and proposes lanes and facets on its own, so the three jobs below are the parts that take judgement or code.

You write two files, scratchboard.json and scratchboard.parser.mjs, both at the repo root, and you ask the user before each. None of the three jobs changes a ticket.

Moving a card is the other job and it needs no config. A lane that matches on a field is moved by writing that field in the ticket, one line, in the vocabulary the repo already uses. The board never writes it, because the board is read-only.

The vocabulary a card is moved with

Read the repo's own values first, from its lanes in scratchboard.json and from the tickets themselves, and write what is already there. The list below is the vocabulary the skills speak in, which is what a repo that has none of its own should use.

Value Means
needs-triage A maintainer needs to evaluate this ticket
needs-info Waiting on the reporter for information
ready-for-agent Fully specified, ready for an agent working alone
ready-for-human Needs a human to implement it
wontfix Will not be actioned
done Shipped and verifiable in the history

The first five are the canonical triage roles. done is scratchboard's own terminal state, because the five are a triage queue rather than a lifecycle. A repo may carry values outside both sets, as this one carries deferred for work someone looked at and chose later. Those pass through untouched, take their lane from local config, and are never rewritten into a value from the table.

The reader spec is docs/local-markdown-spec.md in the scratchboard repository. It names every value the board recognizes, the file shapes it reads, and what happens to input it does not recognize. Read it rather than guessing, and do not restate it in a repo's own docs.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
