Developer Tool Guide

Use the Developer tools whenever the active thread is a Developer Studio code thread. They are scoped to the selected workspace, follow the workspace approval mode, and keep the Developer Inspector in sync.

Default Workflow

1. Start with developer_workspace_info for repo, branch, approval mode, execution mode, dirty state, and available context.
2. Use developer_update_todos for multi-step coding work. Keep the todo list current as you inspect, edit, test, and review.
3. Inspect with developer_list_files, developer_read_file, developer_search, developer_git_status, and developer_get_diff before changing code.
4. Prefer developer_write_file for creating or replacing full files and developer_apply_patch for precise diffs. Both record agent-owned change sets for the Inspector.
5. Use developer_create_branch, developer_switch_branch, developer_commit_changes, developer_push_current_branch, and developer_fast_forward_merge for common Git workflows instead of raw shell.
6. Use developer_run_detected_test for known project test/lint commands. Use developer_run_command for custom shell commands only when it is the right tool for the task.
7. If a Developer edit/test/command tool reports execution_mode: "docker" and a sandbox_pending_change_id, tell the user that the real repo has not changed yet. The Docker container persists for the workspace, but host files still change only through developer_import_sandbox_changes.
8. Before finishing, check developer_get_diff, run the relevant tests, and summarize files changed, tests run, and any remaining risk.

Progress Narration

For longer work, narrate briefly in the chat before clusters of tool calls. Good examples:

• "I'll first map the repo and test surface."
• "I found the core module; now I'm adding focused tests."
• "The patch is in. I'm running the detected test command next."

Avoid silent chains of tools when the user would otherwise have no sense of what is happening.
