Code Execution (bulk-operation token saver)

Runs a local Python runtime to handle bulk file operations and return only summaries, cutting token use by 90%+.

Dev & CodingIntermediate★ 678⑂ 96AI score 9/10Last updated: Jul 25, 2026

What it does

Instead of pulling whole source files into the conversation, this skill calls a local Python runtime (execution_runtime) to do the work and returns summaries only.

  • fs: copy/paste line ranges, search & replace, batch copy
  • code: find functions/classes, analyze dependencies and complexity (metadata only, never full source)
  • transform: project-wide identifier rename, debug-statement removal, batch refactor
  • git: status / add / commit / push

It includes a savings table: ~90% for 10 files, ~99% for 100 files.

Who it's for

  • Python developers doing frequent large-scale refactors
  • Anyone who keeps hitting context limits on multi-file tasks
  • Teams wanting automated repo-wide complexity audits

Examples

  1. Rename across 50 files: transform.rename_identifier('.', 'oldName', 'newName', '**/*.py') → returns {files_modified: 50, total_replacements: 247}
  2. Extract utility functions: locate .*_util$ functions with code.find_functions, then move them via fs.copy_lines + fs.paste_code into utils.py
  3. Audit 100 files: use code.analyze_dependencies to list only files with complexity above 15

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the code-operations-plugin/skills/code-execution folder from the GitHub repo mhattingpete/claude-skills-marketplace into my ~/.claude/skills/code-execution/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/mhattingpete/claude-skills-marketplace.git && mkdir -p ~/.claude/skills && cp -r claude-skills-marketplace/code-operations-plugin/skills/code-execution ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal and clone the repo: git clone https://github.com/mhattingpete/claude-skills-marketplace.git
  2. Create the skills folder: mkdir -p ~/.claude/skills
  3. Copy the skill: cp -r claude-skills-marketplace/code-operations-plugin/skills/code-execution ~/.claude/skills/
  4. Install the Python runtime: if installed as a plugin, run ~/.claude/plugins/marketplaces/mhattingpete-claude-skills/execution-runtime/setup.sh; if you cloned manually, run execution-runtime/setup.sh inside the cloned folder.
  5. Restart Claude Code, then try a request like "rename oldName to newName across every .py file in this repo" to trigger the skill.
  6. Commit your work with git first — the transform functions edit files in place.
