    expected: "The agent should demonstrate the 'grep -> read' pattern: first using `grep_content` to locate the file and line number, and then using `read_files` with a specific line range to get the context, rather than reading the entire file."
    why_human: "Programmatic verification can only confirm that the guiding text exists in the tool descriptions. It cannot confirm that the guidance is effective in steering an LLM agent's behavior, which is the core of the phase goal."

# Phase 2: Agent Workflow Optimization Verification Report

**Phase Goal:** Weak agents discover and efficiently use the grep → read pattern; tool descriptions guide toward optimal token usage.
**Verified:** 2026-01-26T14:12:10Z
**Status:** human_needed
**Re-verification:** No — initial verification

## Goal Achievement

All programmatically verifiable must-haves for this phase have been met. The tool descriptions and project documentation have been updated as planned. However, the ultimate goal of influencing AI agent behavior can only be confirmed through observation.

### Observable Truths

| 1   | The `grep` tool's description explicitly guides the agent to use it for locating file paths.        | ✓ VERIFIED | `src/fs_mcp/server.py` docstring for `grep_content` states its purpose is to "locate file paths and line numbers".                |
| 2   | The `grep` tool's description contains a clear, copy-pasteable example of the 'grep -> read' workflow. | ✓ VERIFIED | `src/fs_mcp/server.py` docstring for `grep_content` includes a two-step code example.                                               |
| 3   | The `read` tool's description is updated to mention its synergy with `grep`.                    | ✓ VERIFIED | `src/fs_mcp/server.py` docstring for `read_files` has a "Workflow Synergy with `grep_content`" section.                     |
| 4   | Project documentation in `PROJECT.md` explains the 'grep -> read' workflow for human developers.  | ✓ VERIFIED | `.planning/PROJECT.md` contains a new section "The Grep -> Read Pattern".                                                         |

| `.planning/PROJECT.md`        | `grep -> read` workflow | A new documentation section.    | ✓ VERIFIED | The file contains a markdown section with this title.                      |

### Requirements Coverage

No requirements from `.planning/REQUIREMENTS.md` were mapped to this phase.

### Anti-Patterns Found

No blocking anti-patterns were found in the modified files.

### Human Verification Required

The core goal of this phase is to influence the behavior of an AI agent. While the necessary documentation and prompts are in place, we cannot programmatically verify that they are *effective*.

| Provide a 'weak' AI agent a task like: "Find where the FastMCP class is initialized and what it does". | The agent should use `grep_content` to find the location, then `read_files` with a line range to inspect, rather than reading the whole file. | We need to observe if the agent's behavior is actually guided by the new tool descriptions as intended. This is a behavioral test. |
