| 5   | `grep_content` returns bounded results with file paths, line numbers, and context. | ? UNCERTAIN  | The implementation appears correct, but is not verified by any tests.                                                                 |
| 6   | `grep_content` handles 'no matches' and 'timeout' scenarios gracefully.           | ? UNCERTAIN  | The implementation appears correct, but is not verified by any tests.                                                                 |

**Score:** 4/6 truths fully verified, 2 uncertain due to lack of tests.

### Gaps Summary

The core goal of integrating `ripgrep` has been mostly achieved. The server correctly checks for the dependency, provides installation instructions, and a `grep_content` tool has been implemented.

However, the phase is incomplete due to a critical gap: **a complete lack of automated tests for the new `grep_content` tool.** While the code appears correct upon inspection, its reliability, edge case handling, and output formatting are not guaranteed. The developer also deviated from the planned file structure, placing the tool logic inside the main server file instead of a dedicated `tools.py`, which is a minor architectural concern. The primary blocker for phase completion is the missing test coverage.
