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

Annotations cover only the generic safety profile (readOnlyHint=false, openWorldHint=true, idempotentHint=false, destructiveHint=false). The description goes well beyond that: it discloses the destination of the side effect ('Files feedback with Replo's team'), the non-idempotent follow-up rule, privacy constraints ('Omit credentials and unrelated customer data'), and an evidence-integrity requirement ('never invent evidence, root cause, or severity'). That is materially more than the structured fields convey.

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 paragraph is front-loaded with purpose and stays dense with rules, so every sentence carries operational weight. There is some redundancy with the schema ('Mark unknowns; never invent evidence' is restated in the reproSteps and description field docs), which slightly inflates length but does not obscure the intent.

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?

With no output schema, the description should say what a successful call yields; it instead only says feedback is filed and the agent should continue, leaving the return value (e.g., a report or ticket ID) unstated. Given the annotations and 80% schema coverage, the rest of what an agent needs to call this correctly is present.

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 80%, so most parameters are self-documenting and a baseline of 3 would apply. The description compensates for the one uncovered field by specifying exactly what belongs in errorContext ('observed errors or request IDs'), and it reinforces projectId sourcing from list_projects. It adds real meaning rather than restating schema text.

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 names a specific action and target ('Report a credible user-reported or directly observed Replo defect, including API, MCP, or documentation defects'), which is far more precise than the title 'Report a bug'. It does not distinguish itself from the closest sibling, submit_feature_request, so an agent still has to infer which filing channel applies. Clear purpose, missing sibling routing.

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 explicit inclusion criteria (credible, user-reported or directly observed Replo defects) and exclusion criteria (bad arguments, missing configuration, fixable site-code mistakes), plus a post-success rule ('Do not resubmit the same report after success'). No alternative tool is named, so the when-to-use is strong but the alternatives branch is absent.

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