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

Annotations disclose readOnlyHint=false and destructiveHint=false, so the write-but-safe profile is already known. The description adds that every field is optional and that nothing downstream depends on the call, which is meaningful context beyond the annotations.

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 purpose, then usage, then the non-dependency caveat. No padding, though the first sentence is slightly verbose in restating 'what worked and what did not'.

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, the description should carry behavioral weight, and it covers optionality, non-destructiveness, and the absence of downstream dependencies. Nothing critical for correct invocation appears to be missing for a simple feedback submission tool.

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% with all 8 parameters individually described, so the baseline is 3. The description only reinforces optionality ('Every field is optional'), which the schema already shows via zero required parameters, adding no new semantic detail.

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 (records) and resource (feedback note about the environment) and scopes it to 'what worked and what did not'. It is clearly distinguishable from siblings, none of which collect feedback, though 'short note' understates an 8-field submission.

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?

Explicitly says when to use it ('when you or the user want to leave feedback') and clarifies that no other tool depends on it, removing any concern about ordering. No alternatives are named, but no sibling offers comparable functionality, so none are needed.

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