Every tool has a clearly distinct purpose. Even overlapping domains like commits (harvest, record, remap) and intervals (clock, annotate, repair) are separated by specific actions and targets. No two tools could be easily confused for the same operation.

The majority of tools follow a consistent verb_noun pattern (e.g., repair_interval, start_effort, add_slice). A few query tools are named as nouns (current, summary, effort_table, effort_detail), which is a minor deviation but still readable and sensible for retrieval operations.

With 21 tools, the surface is substantial but justified by the domain's complexity—covering efforts, intervals, slices, commits, estimates, and queries. Each tool adds distinct functionality, though the count is on the higher end and could feel heavy for simpler use cases.

The toolset provides comprehensive lifecycle coverage: starting and finishing efforts, managing slices (add/close/drop/rename), tracking time (clock in/out, absence), revising estimates, recording commits, and rich reporting (current, table, detail, summary). No obvious gaps or dead ends are apparent.
