scratch

scratch is a skill for Claude Code, Codex from NikiforovAll/scratchpad. It costs 49 tokens per session (2,656 once invoked), scanned A, original, MIT.

A skill for keeping session notes, snippets, command output, diagrams, and other related files in a scratchpad folder with a manifest.

In plain words
What is it for?
Use it to create a scratchpad, add files and metadata, group related documents, and inspect or preview the collected session material.
Why use it?
It provides a consistent place to collect temporary work and track what each file is for without mixing it into the project's source code.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is "related": ["client-sdk", { "pad": "../other/pad", "rel": "feeds" }].

Good fit Use it to create a scratchpad, add files and metadata, group related documents, and inspect or preview the collected session material.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

scratch 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 3d 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 — 217 lines — stays where its author put it; the contents beside it link to each section on GitHub.

scratch — session scratchpads

A scratchpad is a folder with a scratchpad.json manifest; the folder path is its identity (no central store). The CLI never authors, copies, or moves content — you write files with your normal tools, then register them for metadata + preview. Use it for session knowledge worth keeping together, not for the project's real source files.

scratch is on your PATH — run it directly. The skill's base dir is not where the CLI lives; don't look there for an entrypoint to invoke.

The loop

1. CREATE (default parent _scratchpads; create it if absent):
     scratch new "<name>" --dir _scratchpads [--id <session-id>]
   → creates <parent>/<slug>/ + scratchpad.json.

2. WRITE files into the pad dir with your normal tools (e.g. <slug>/notes.md).

3. REGISTER each file to track (group multi-doc pads with --group):
     scratch add "<name>" <file> --title "..." --desc "why it exists" \
       --type note --tag a,b --group "Findings"

4. INSPECT:  scratch ls           # pads under root
             scratch ls "<name>"  # files in a pad
             scratch show "<name>" <file>
             scratch comments "<name>"   # inline comments left in the viewer
             # add --json to `ls`/`show <file>`/`comments` for machine-readable output (agents)

5. BROWSE:   scratch ui "<name>"  # see viewer note — launch backgrounded

To extend an existing pad later, skip step 1 — ls to find it, write, add.

Scripting (--json)

ls and show <pad> <file> accept --json for parseable output (paths are relative, forward-slashed — never absolute, safe across shells/platforms):

  • scratch ls --json → { root, pads: [{ name, rel, files }] }
  • scratch ls "<name>" --json → { name, id, rel, files: [<entry>] }
  • scratch show "<name>" <file> --json → { metadata, content } (metadata null if unregistered)
  • scratch comments "<name>" [<file>] --json → { pad, comments: [...] } (see below)

Errors stay as text on stderr; stdout carries only the JSON, so pipe to jq freely.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

scratch is a skill published in the GitHub repository NikiforovAll/scratchpad (16 stars, last pushed 3d ago), licensed MIT. It adds 49 tokens to every session and 2,656 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
