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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the write-but-non-destructive profile is covered. The description adds nothing beyond that - no mention of authentication needs, rate limits, whether submissions are public, or what happens after submission. For a mutation tool it should disclose more.

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?

A single front-loaded sentence with no filler; the purpose is stated immediately. It is efficient, though minimal relative to what the tool could usefully explain.

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 a simple three-parameter tool with a required message, full schema coverage, and annotations covering the safety profile, the description is minimally sufficient. It is missing any routing guidance against sibling reporting tools, which is the main contextual gap.

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%, so the schema already documents page, type, and message including the enum values and the 5000-char cap. The description loosely mirrors the type enum ('bug report, suggestion, general feedback') but adds no syntax, format, or constraint detail beyond the schema, so the baseline of 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 states a specific verb (Submit) and resource (feedback about the PCC network) and enumerates the kinds of feedback accepted (bug report, suggestion, general feedback). It is clear what the tool does, but it does not differentiate itself from nearby siblings such as pcc_report or send_support_message that could also carry user-submitted reports.

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?

There is no guidance on when to choose this tool over alternatives like pcc_report, send_support_message, or report_anomaly, and no stated preconditions. The agent must infer usage purely from the tool name.

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