# Phase 2 Plan 1: Agent Workflow Optimization Summary

**Enhanced tool descriptions and documentation to guide agents and developers towards the efficient `grep -> read` workflow.**

## Performance

- **Duration:** 5 min
- **Tasks:** 3/3
- **Files modified:** 2

## Accomplishments

- Updated the `grep_content` tool's docstring to explicitly state its purpose is locating file paths and line numbers, including a clear example of the two-step workflow.
- Updated the `read_files` tool's docstring to reference `grep_content`, explaining their synergy and reinforcing the `grep -> read` pattern.
- Added a new "Agent Workflows" section to `.planning/PROJECT.md` to onboard human developers to this token-efficient pattern.

## Task Commits

Each task was committed atomically:

1. **Task 1: Update `grep_content` tool description** - `99d17d4` (feat)
2. **Task 2: Update `read_files` tool description** - `7e85d57` (feat)
3. **Task 3: Document the 'grep -> read' workflow in PROJECT.md** - `053acd0` (docs)

## Files Created/Modified

- `src/fs_mcp/server.py` - Updated docstrings for `grep_content` and `read_files` to guide agent behavior.
- `.planning/PROJECT.md` - Added documentation for human developers on the `grep -> read` workflow.

## Decisions Made

None - followed plan as specified.

## Deviations from Plan

None - plan executed exactly as written.

## Next Phase Readiness

The agent workflow guidance is now implemented. The project is ready for the final phase of production polish and cleanup.
