Each tool has a clearly distinct purpose: get_changes retrieves captured changes, apply_changes marks them as applied, and clear_changes empties the buffer. There is no overlap or ambiguity between them.

All tool names follow a consistent verb_noun pattern with underscores: get_changes, apply_changes, clear_changes. The verbs are imperative and the noun is uniform, providing a predictable and clear naming scheme.

With only 3 tools, the set is perfectly scoped for managing a single buffer of visual changes. Each tool serves a necessary and distinct function, and no tool feels extraneous or missing for this focused purpose.

The tool set covers the core operations for managing the changes buffer: reading, marking as applied, and clearing. While there is no tool to revert individual changes or directly apply them to files, those functions are intentionally handled externally, making the set complete for its defined scope.
