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

The description discloses behavioral expectations: feedback is a note to the team, not a ticket, so no promise of fixes; there is no reply, so the agent shouldn't wait for one. This goes beyond the annotations, which only indicate non-read-only and non-destructive. It doesn't mention any side effects like logging or rate limiting, but for a feedback tool this is sufficient.

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 well-structured with clear clauses, but it has some redundancy (e.g., repeating 'Feedback is a note to the team, never a ticket' and 'do not promise the operator it will be fixed'). It is not overly long and the key information is front-loaded, but it could be trimmed slightly without losing clarity.

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?

The description covers the tool's purpose, usage triggers, exclusions, and expected outcomes (no reply). It is missing parameter-level semantics and doesn't mention what happens after submission (e.g., where the note goes), but given the tool's simplicity and the annotations, it provides enough context for correct invocation. The lack of output schema is acceptable since the description notes there is no reply.

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?

The schema has five parameters (kind, detail, summary, projectId, toolContext) but the description only implicitly references 'kind' by listing the feedback types. It provides no explanation of what each parameter means, their requiredness, or how to fill them, leaving the agent to infer from names alone. This is a significant gap given the schema coverage is 0%.

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 clearly states the tool's purpose: to file a note to the VarynForge team, enumerating the types of feedback (bug, missing capability, friction, idea). It also distinguishes itself from other tools by specifying what it is not (a ticket system) and explicitly excluding entitlement walls, making it unambiguous.

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 provides explicit when-to-use guidance: call when encountering something VarynForge cannot do, confusing results, or operator frustration/wishes. It also gives negative guidance, telling the agent not to file payment/rate/feature errors, which are working as designed. This is exceptionally clear.

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