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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is covered. The description adds useful return-content context (it surfaces linked bug IDs and an open-bug count), which matters since there is no output schema, but it says nothing about ownership enforcement, pagination, or failure modes.

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; it leads with the action and immediately qualifies scope and return contents.

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 appropriately sketches the return payload (bug IDs, open-bug count) and annotations cover the safety profile, so an agent can call it. Gaps remain: the optional sessionId/executionId parameters and the scope implied by 'owned' are never explained in the description.

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 carries parameter documentation and the baseline is 3. The description's 'owned report' phrasing loosely touches the reportId/projectId semantics but adds no format or usage detail beyond what the schema provides.

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?

States a specific verb (Read) and resource (one owned authored report) and even names what the payload contains (linked bug IDs, open-bug count). The singular 'one' implicitly contrasts with the plural list_reports sibling, though no sibling is named explicitly.

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 only asserts what the tool does; it gives no when-to-use, no when-not-to-use, and names no alternative (e.g., list_reports for enumeration or update_report for mutation). 'Owned' hints at a precondition but nothing is spelled out.

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