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

The description adds real context beyond the lone destructiveHint annotation: write semantics, the trace_id attachment model, and the POST /feedback endpoint. However, it never addresses why the operation is flagged destructive (is existing feedback overwritten?), nor permissions/auth needs, so the annotation's implication is left unexplained.

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 sentences, front-loaded with the uppercase WRITES verb, followed by usage context and the endpoint mapping. No filler or redundancy that would slow an agent's decision.

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?

With no output schema and minimal annotations, the description should carry more burden than it does: the return value (e.g., created feedback id), authentication requirements, and the destructive-flag rationale are all absent. It is adequate to invoke the tool but incomplete on consequences and results.

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 100% and each of the four parameters carries its own description, including the same -10..10 and 0..1 ranges repeated in the description. The description therefore adds little parameter-level meaning beyond the schema; 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 and resource ('WRITES a feedback record'), plus the attachment key ('attached to a request/trace by trace_id') and the underlying endpoint. Every sibling tool is a read (get_/list_), so the write nature alone distinguishes it unambiguously.

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?

'Use for logging a quality score ... with an optional weight ... and metadata' gives concrete when-to-use context. It stops short of stating exclusions or alternatives, though no sibling offers an overlapping write operation, so the practical gap is small.

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