What it does
Scratchpad is an agent skill from Effect-TS/effect-smol. Extract the JSDoc example nearest the active source selection or cursor into ./scratchpad as a TypeScript file. Use when the user asks to dump, copy, open, or try a source example in scratchpad.
Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `agents/openai.yaml`).
It sits in Development, covering Technical documentation. It works with TypeScript. The repository describes itself as: Core libraries and experimental work for Effect v4. The licence is MIT.
When your agent uses it
- The user asks to dump
- Try a source example in scratchpad
Example prompts
- “/scratchpad”
Requirements
- Node.js
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Determine the source path and line
- Run
- If the script exits with code 2 because there is no obvious runner, ask the
- Report the created path as a clickable file link. This is the deterministic
- Do not run the scratchpad file unless the user explicitly asks.
What it can do on your machine
Read from SKILL.md and the folder at commit 3a1128c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
node
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Scratchpad loads about 459 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 216 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

- scratchpad
- description
- Extract the JSDoc example nearest the active source selection or cursor into ./scratchpad as a TypeScript file. Use when the user asks to dump, copy, open, or try a source example in scratchpad.
Use this skill to create a scratchpad TypeScript file from the JSDoc **Example**
nearest the user's active source cursor or selection.
Workflow
Determine the source path and line:
- Use the IDE active file and selection/cursor line when present.
- Use an explicit file and line when the user provides them.
- If no line or selection is available, ask for it.
Run:
sh node .agents/skills/scratchpad/scripts/extract-example.mjs <source-path> <line>If the script exits with code 2 because there is no obvious runner, ask the user whether to preserve the example exactly, name an Effect value to run, or cancel.
- To preserve exactly, rerun with
--mode preserve. - To run a specific Effect value, rerun with
--runner <identifier>.
- To preserve exactly, rerun with
Report the created path as a clickable file link. This is the deterministic way to open it in the code pane.
Do not run the scratchpad file unless the user explicitly asks.
Behavior
The script chooses the example whose
**Example**section contains the line; otherwise it chooses the first following example; otherwise the nearest previous example.Filenames are derived from the source file and example title, for example
scratchpad/Schedule-retrying-and-repeating-effects.ts.Existing files are not overwritten. The script appends a numeric suffix.
In auto mode, if a top-level
programbinding exists, the script appends:ts Effect.runPromise(program).then(console.log, console.error)If the example already contains an Effect runner, the script preserves it.

Questions about Scratchpad
What does Scratchpad do?
Extract the JSDoc example nearest the active source selection or cursor into ./scratchpad as a TypeScript file. Scratchpad is an agent skill from Effect-TS/effect-smol./scratchpad as a TypeScript file.
When should I use Scratchpad?
Scratchpad fits situations like: the user asks to dump; try a source example in scratchpad.
How do I install Scratchpad in Claude Code?
Run `npx skills add Effect-TS/effect-smol --skill scratchpad -a claude-code`. Or copy the skill folder (.agents/skills/scratchpad in Effect-TS/effect-smol) into .claude/skills/scratchpad in your project. Claude Code loads it when a task matches its description.
How do I install Scratchpad in Codex?
Run `npx skills add Effect-TS/effect-smol --skill scratchpad -a codex`. Or copy the skill folder (.agents/skills/scratchpad in Effect-TS/effect-smol) into .agents/skills/scratchpad in your project. Codex loads it when a task matches its description.
Can I use Scratchpad in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Effect-TS/effect-smol --skill scratchpad -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/scratchpad, .gemini/skills/scratchpad, .github/skills/scratchpad and .opencode/skills/scratchpad in your project.
What does Scratchpad need to run?
Going by SKILL.md and its folder, Scratchpad needs JavaScript for the scripts in its folder and the command-line tools its instructions call (node). Our summary lists: Node.js.
Does Scratchpad access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Scratchpad safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Scratchpad use?
Scratchpad is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Scratchpad use?
About 459 tokens (SKILL.md is roughly 1.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Scratchpad?
Skills that share tags, products or a category with Scratchpad: Add Package (remix-run/remix, 33k stars), evlog Enricher Creator (evloghq/evlog, 1.9k stars), Enforce Rules For Typescript (moeru-ai/airi, 50k stars) and Standard Jsdoc (backpine/effect-worker-mono, 132 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
