Description

  • Copilot Chat Extension Version: 0.32.2025100101
  • VS Code Version: 1.105.0-insider (Universal)
    • Commit: 6e60e679fc6b6a512edbed9a750d7c581
  • OS Version: Darwin arm64 24.6.0
  • Feature (e.g. agent/edit/ask mode): agent
  • Selected model (e.g. GPT 4.1, Claude 3.7 Sonnet): GPT-5-Codex

The get_changed_files tool doesn't seem to return changes when the model sets the sourceControlState to staged.

get-changed-files.copilot.md

Steps to Reproduce:

  1. Tell Copilot to use the get_changed_files tool and explicitly set the sourceControlState parameter.
* Use the get_changed_files tool to get the staged changes and build a commit message based on the staged git diff.
  * Must set `sourceControlState` to `staged` to build the correct commit message.

Contributor guide

Research direction
Examine the get changed files function to understand why the sourceControlState parameter is ignored and ensure it is properly passed to the underlying git diff command.
