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

The annotations provide no positive hints (all flags false), so the description carries the transparency burden. It discloses that submitting 'files' feedback and that replies arrive 'on the feedback page', that list returns filed feedback plus replies, and that an API key is required. It does not elaborate on side effects or reply timing, but it covers the essential behavior.

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 dense and each clause earns its place: action modes, parameter hints, intended use, exclusions, return shape, and auth requirement. It is a long run-on sentence, but it is compact relative to the information it conveys and front-loaded with the primary purpose.

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?

Even with no output schema, the description provides the return shape for both actions ('submit → id, kind, title, chain, status, reply, created_at; list → feedback'), the required API key, and clear sibling boundaries. For a two-action tool with no nested objects, nothing critical is missing for an agent to select and 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 description coverage is only 17% (only action is documented), so the description must compensate. It enumerates kind values ('feature' | 'chain' | 'praise' | 'complaint' | 'other'), marks title as expected with body and chain optional, and makes status conditional on list. It still leaves body, chain, and status semantics somewhat implicit, but it adds substantial meaning beyond the bare schema.

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 states the exact function ('Product feedback to FlexYield') and enumerates the two action modes, submit and list. It also names the sibling tools it is not (manage_tickets, join_enterprise_wishlist), so an agent can clearly distinguish it.

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?

It explicitly says when to use the tool: 'ideas, a chain you want added, or praise and complaints that need no fix on your account.' It also gives concrete exclusions with named alternatives: failing calls/refusals → manage_tickets, enterprise terms → join_enterprise_wishlist.

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