What is scratchpad CLAUDE.md?

A project instruction file for scratch, a Bun-based command-line tool that organizes agent knowledge into folders called scratchpads and provides a read-only visual viewer. A monorepo is one repository containing several related parts of a project.

Use it when changing the scratch CLI, its viewer, tests, or monorepo architecture. It explains commands, manifests, task-checkbox persistence, Excalidraw scene saving, and the viewer under src/ui/.

It documents the tool's layout and protects its key rule: the CLI registers files and metadata but normally does not create, copy, or move their contents.

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.

Model	Per session	Once invoked

Security

Grade A, and why

scratchpad CLAUDE.md 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 1mo 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 — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.

What this is

scratch is a CLI-first tool that organizes agent knowledge into scratchpads: a folder + a scratchpad.json manifest, with a read-only visual viewer. Runs on the Bun runtime.

Core invariant (do not violate): the CLI never authors, copies, or moves file content. It only creates pad dirs, writes manifests, and tracks metadata. The user/agent writes files with their normal tools; scratch add just registers them. A pad is just a folder containing scratchpad.json — the folder path is its identity. There is no central store/index.

Three deliberate exceptions (don't "fix" them as violations), the first two in src/ui/launch.ts:

Clicking a rendered GFM task checkbox in the viewer flips that single [ ]/[x] marker in the source file (persistFileCheckbox). Line-addressed; verifies the line still IS a task marker before writing.
Saving from the viewer's in-place Excalidraw editor writes the edited scene JSON back to its .excalidraw file (persistExcalidrawScene). The user drew the content; the CLI only persists it — scoped to manifest-registered .excalidraw targets and validated with parseScene first.
scratch import (src/import.ts, cmdImport in commands.ts) rebuilds a pad from a scratch export HTML page: embedded file contents are written back to disk and scratchpad.json is regenerated from the embedded metadata. The content is the user's own export and the restore is explicit; paths that are absolute or contain .. are rejected, and the target must be empty unless --force.

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.
