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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, covering the safety profile. The description adds only the payload contents, which the output schema already documents, and does not mention permissions, rate limits, or side effects. It is consistent with annotations but offers little beyond structured fields.

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?

One tight sentence with the verb and resource front-loaded. The field enumeration is slightly redundant given the output schema, but the description remains efficient and easy to scan.

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?

A simple read tool with annotations covering safety and an output schema covering returns, so the description needn't explain those. However, the sole required parameter is undocumented in both schema and description, and there is no usage guidance relative to siblings, leaving avoidable ambiguity.

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 0% and the single required parameter report_id has no schema description. The phrase 'for a report's' gives a weak hint that the parameter identifies a report, but it never names report_id, states that it is required, or gives its format.

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?

Specific verb 'Fetch' and resource 'gamified progress payload for a report's diligence checklist', with enumerated metrics (percent complete, knowledge score, counters by state, critical-items-verified, auto-verified count). It implicitly separates itself from sibling get_diligence_checklist by being a progress summary, but it never explicitly names or contrasts any sibling.

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 indication of when to use this versus get_diligence_checklist or list_diligence_items, no prerequisites, and no exclusions. Usage is only implied by the tool name and purpose statement.

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