report_done creates a completion receipt, situation_report summarizes current status, recent_events fetches event details by id, and focus_change records a focus shift. The purposes are mostly distinct, though report_done and situation_report both involve reporting and could be confused in edge cases.

All names use snake_case and are readable, but they follow mixed patterns: report_done is verb-participle, recent_events is adjective-noun, while situation_report and focus_change are noun-noun. There is no single predictable verb_noun convention.

Four tools is a reasonable, well-scoped set for a lightweight steward assistant. Each tool appears to earn its place, though the surface is minimal enough that it may feel slightly thin for full workspace tracking.

The set covers reporting completion, summarizing status, retrieving event details, and recording focus changes. However, it lacks explicit workspace lifecycle operations and event discovery beyond lookup by known id, which may cause dead ends for agents.
