Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| read_fileA | To read the contents of a file with line numbers. Returns numbered lines. For large files, output is truncated to head+tail unless a specific range is given via start_line/end_line (1-based, inclusive). |
| list_directoryA | To read the structure inside a directory, either surface level or recursively. Results will be truncated if they exceed 500. |
| write_fileC | To completely overwrite a file, after it's snapshot has been taken. (or to create a new file) |
| edit_file_linesA | To replace a specific chunk in a file from start_line inclusive to end_line inclusive with content(one based indexing for lines), after it's snapshot has been taken. |
| str_replaceA | Replace an exact occurrence of old_str with new_str in a file. old_str must appear exactly once in the file. No line numbers needed — matches on content. |
| undo_file_editA | Revert file before the most recent mutating tool was called on it. This will be recorded in the master ledger as an undo operation. |
| undo_globalA | Revert the last file edited before the most recent mutating tool was called on it(undo_file_edit is also mutating) |
| revert_fileB | Discard all AI changes for this specific file. |
| reset_sessionD | Wipe all AI changes across the directory |
| get_session_diffB | Get a diff of what exactly was modified in a file from its orignal state. |

Scored across 10 tools
Most tools have distinct purposes, but undo_file_edit and undo_global could be confused due to similar names and descriptions. edit_file_lines and str_replace both replace content, though their methods differ. Overall, the overlap is minor.
Tool names follow a verb_noun snake_case pattern (e.g., edit_file_lines, list_directory, write_file). However, 'str_replace' deviates from the pattern (no underscore after verb), and 'undo_file_edit' is slightly awkward. Overall consistent.
10 tools is appropriate for the scope of file editing and version control. Each tool has a clear role without being excessive or insufficient.
The tool set covers reading, writing, editing (two methods), listing, diff, undo, revert, and session reset. Missing features like manual snapshot saving or session listing are minor gaps given the automatic snapshotting implied.
