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

Annotations only supply readOnlyHint=false, so the description adds real value: it discloses that the tool works with or without an API key and that contact_email is only needed in the keyless case for a reply. It does not say what happens after submission (ticket id, storage, who sees it), leaving that gap.

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 tight sentences, front-loaded with the purpose and followed by content restrictions and the key/contact_email caveat. The trailing '(capability: feedback.send)' tag is internal noise that adds nothing for an agent.

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?

Adequate for a five-parameter mutation with no output schema, but it omits what the caller gets back after submitting and does not describe two of the five parameters, so an agent must open the schema to fill in gaps.

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 0%, so the description must carry the load; it does well for contact_email (conditional on missing key and wanting a reply) and implies the kind categories, but 'tool' and 'client' are never explained and the enum values are only paraphrased loosely.

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 (tell/submit) and resource (feedback to RepuTend) and enumerates the exact situations covered: missing tool/feature, a tool that failed or answered wrong, or other problems. No sibling tool covers feedback, so an agent can immediately place it in the toolset.

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?

Gives clear triggering conditions ('a tool or feature you needed and did not find', 'a tool that failed') plus explicit content exclusions (no review text, reviewer names, secrets). It stops short of naming an alternative for non-feedback needs, but no sibling competes here.

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