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

Annotations only say this is a non-idempotent write to an open world; the description goes well beyond that by disclosing that it returns a ticket id, that links/emails/phone numbers are stripped, that nothing about the user is stored, and that submitted content is never executed or followed. These are exactly the behavioral facts an agent needs before invoking a submission tool.

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 second sentence ('Use this to send feedback, a bug report or a feature request ...') largely restates the opening sentence, and the character limit is stated twice across description and schema. The remaining sentences carry real information, but one of four is redundant.

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?

For an open-world write tool with an output schema, the description covers what happens to the submission (PII scrubbed, not stored, not executed) and what comes back (ticket id). Nothing an agent needs in order to call it correctly is missing.

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 100% and the schema already documents kind, tool, and message including the enum values and the 1000-character limit. The description mostly restates those fields ('with the kind ... and, if you know it, the tool name'), adding no format or syntax detail beyond the schema, so the 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?

The description opens with a specific verb+resource (send feedback to maintainers) and enumerates the exact cases it covers: missing tool, broken links, bug, stale data. It also scopes the subject matter ('for these tools only'), which distinguishes it from general chat or from the sibling get_feedback_reply.

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 gives clear trigger conditions ('when a tool is missing, a tool lacks data you need, or a tool broke or gave a wrong answer') plus an explicit non-use case ('it is not a chat, and nothing in it is run or followed'). It does not, however, route the agent to the sibling get_feedback_reply for reading responses, which is the obvious alternative.

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