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

Annotations declare readOnlyHint=false, idempotentHint=false, and destructiveHint=false, so the mutation/repeatability profile is already covered. The description adds a genuinely useful auth prerequisite (api_key from register_agent), but says nothing about what happens on submission, whether feedback is stored/attributed, or any rate limits.

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?

Two short sentences, front-loading the authentication prerequisite the agent needs before calling. The parenthetical is terse and slightly ambiguous, but there is no padding or redundancy.

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 4-param mutation tool with full schema coverage, annotations, and no output schema, the description covers the auth requirement but omits the one thing structured fields cannot convey: when to choose this tool over request_feature or submit_observation. Adequate but with a clear routing gap.

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%, with each parameter documented (api_key source, message, severity values, feedback_type values). The description adds no meaning beyond the schema, so the baseline of 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 ("Submit platform feedback"), which is clear enough to separate it from the many read/query siblings. It does not, however, explicitly distinguish itself from near-neighbors like request_feature, submit_observation, or submit_signal, leaving the agent to infer the boundaries.

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?

The description only says an api_key is required and points to register_agent as the source. It gives no when-to-use guidance and no guidance on how this differs from request_feature or submit_observation, which are the most plausible alternatives for an agent with feedback-like intent.

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