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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds a meaningful ownership/authored constraint and indicates that the report's current open-bug count is returned, but it does not disclose not-found behavior, error conditions, or how the open-bug count is computed.

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 one efficient sentence, front-loaded with the action and resource, and contains no redundant clauses or filler. Every word contributes meaning without requiring the reader to parse unnecessary context.

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 tool with four parameters and no output schema, the description is only partially complete. It omits any explanation of sessionId and executionId, gives no return structure beyond 'linked bug IDs and current open-bug count,' and provides no guidance on ownership failures. The annotations cover safety, but an agent still lacks enough context to call this correctly in all scenarios.

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?

With schema description coverage at 0%, the description carries the full burden for explaining parameters, yet it never names or explains reportId, projectId, sessionId, or executionId. The phrase 'read one report' only weakly implies reportId; the two optional parameters are entirely unexplained, leaving agents without the information needed to populate them confidently.

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 ('Read') and resource ('one owned authored report'), explicitly singles out one report rather than a list, and specifies the returned contents (linked bug IDs and current open-bug count). This clearly distinguishes it from siblings like list_reports, create_report, and update_report.

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?

No guidance is given about when to use this tool versus alternatives such as list_reports (to find a report) or get_project_status. There are no exclusions, prerequisites, or references to sibling tools, leaving the agent to infer usage solely from the verb 'Read' and the word 'one.'

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