What happened?

When developing a custom skill inside the .gemini/skills/ directory using Python and a package manager like uv (which creates a local .venv folder), the Gemini CLI automatically maps and shares the entire .venv directory with the model.

Any attempts to ignore this folder using standard .gitignore or .geminiignore files placed directly in the skill directory (or its subdirectories) are completely ignored by the CLI parser.

Impact

  • Token waste: Sending thousands of irrelevant library files to the LLM context.
  • Performance issue: Unnecessary local file mapping slows down the execution.
  • UX degradation: The terminal log hits the 200 items limit instantly, obscuring the actual relevant source files from the user's view.

What did you expect to happen?

The CLI should evaluate the skill context efficiently. It should either:

  • Ignore common heavy development directories by default (.venv, node_modules, pycache, .git).
  • Explicitly respect .gitignore or .geminiignore rules located within the skill's root directory.
