tp_update_event

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

No annotations are provided, so the description must fully disclose behavior. It only says 'Update an event,' disclosing nothing about update semantics (e.g., partial update, field replacement, list handling), side effects, or required permissions. This is a serious gap for a mutation tool.

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?

The description is a single, direct sentence with no filler or redundancy. It is efficiently front-loaded and easy to parse, though minimal.

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 tool with 10 parameters, no output schema, and very low schema description coverage, the description is severely incomplete. It fails to explain the update workflow, required inputs, or how this tool behaves compared to nearly identical sibling tools, leaving the agent without enough context to invoke it correctly.

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 coverage is only 20%, and the description adds no parameter information. The schema's own descriptions for athlete and workout_ids are helpful, but the description does not compensate for the other 8 undocumented parameters or explain their roles in an update operation.

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?

The description clearly states the action (update) and the resource (an event), making the primary purpose understandable. However, it does not explicitly distinguish it from sibling tools like tp_create_event or tp_delete_event, aside from the verb itself.

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 guidance on when to use this tool versus alternatives such as create or delete event. No mention of prerequisites like having an existing event_id or whether this tool replaces or merges fields, leaving the usage context unclear.

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