Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 |
|---|---|---|
| Fable 5 | $0.00047 | $0.00424 |
| Opus 5 | $0.00023 | $0.00212 |
| Sonnet 5 | $0.00009 | $0.00085 |
| Haiku 4.5 | $0.00005 | $0.00042 |
Grade A, and why
scratchpad 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 yesterday.
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.

What it actually says
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:
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:Effect.runPromise(program).then(console.log, console.error) -
If the example already contains an Effect runner, the script preserves it.
What ships with it
2 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.

scratchpad is a skill published in the GitHub repository pingdotgg/t3code (21,041 stars, last pushed 2d ago), licensed MIT. It adds 47 tokens to every session and 424 once invoked, about $0.0002 per session on Opus 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.
