# Python Scratchpad > Use the existing Python execution tools as a scratchpad for calculations, data transformation, and quick script-based validation. Use when this capability is needed. - Skill: `tomevault-io/python-scratchpad` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/python-scratchpad` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/python-scratchpad/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/python-scratchpad --- # Python Scratchpad Use this skill when the task benefits from a short Python script instead of pure reasoning. This skill is especially useful for: - arithmetic and unit conversions - validating regexes or parsing logic - transforming JSON, CSV, or small text payloads - checking assumptions with a small reproducible script Requirements: - The agent should have access to `execute_code`. Workflow: 1. If the task needs computation or a repeatable transformation, activate this skill. 2. If you need examples, call `read_skill_file` for `references/examples.md`. 3. Write a short Python script for the exact task. 4. Prefer `execute_code`. 5. Use the script output in the final answer. 6. Keep scripts small and task-specific. Rules: 1. Prefer standard library Python. 2. Print only the values you need. 3. Do not invent outputs without running the script. 4. If `execute_code` is not available, say exactly: `No Python execution tool is configured for this agent.` 5. Do not claim there is a generic execution-environment problem unless a tool call actually returned such an error. Expected behavior: - Explain the result briefly after using the script. - Include the computed value or transformed output in the final answer. --- > Source: [OpenBMB/ChatDev](https://github.com/OpenBMB/ChatDev) — distributed by [TomeVault](https://tomevault.io).
