Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description usefully discloses the automatic calendar-scheduling side effect and the REST endpoint, which is genuine added context beyond the sparse annotations. However, it never explains the destructiveHint=true (what it may overwrite/consume), auth/permission needs, or how scheduling interacts with existing events.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short, front-loaded sentences with no filler; the core purpose leads. The REST endpoint line is slightly low-value for an agent but harmless and does not bloat the text.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 9-parameter create tool with no output schema and only a destructiveHint annotation, the description leaves the scheduling mechanics (how timeChunksRequired/chunk sizes affect placement, what happens to existing blocks) unexplained. The schema covers parameters, but the auto-scheduling behavior an agent should anticipate is only gestured at.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents all 9 parameters including the ISO formats, enums, and chunk semantics. The description adds no parameter-level detail, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource ('Create a new task') and adds the key behavioral fact that Reclaim auto-schedules it into the calendar. It is implicitly distinguishable from siblings like reclaim_update_task and reclaim_delete_task, though it never names them explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use guidance and no mention of alternatives. It does not say when to prefer this over update_task or how it relates to add_time/start_task. The only contextual sentence is about scheduling behavior, not selection criteria.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
