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

Annotations already declare readOnlyHint=true and idempotentHint=true, so the safety profile is covered. The description adds that the response includes 'fix and verification instructions,' which is useful content context. However, it does not disclose any further behavioral traits like result ordering, pagination semantics beyond the limit parameter, or the distinction between fix tasks and other task types.

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 a single, well-front-loaded sentence with no filler. The primary action and resource appear first, and the instructional content detail adds value without bloat. Every word earns its place.

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 read-only list tool with full schema coverage and readOnly/idempotent hints, the description is largely complete. It mentions that fix and verification instructions are included, which gives the agent a sense of the response content. A small gap is the lack of explicit guidance on the default behavior or the relationship between fix tasks and the site_id, though these are partially inferred from the schema and sibling context.

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 all three parameters (limit, status, site_id) are already documented with types, constraints, and meaningful descriptions. The tool description does not add parameter-level detail beyond the schema; saying 'for a website' aligns with site_id but does not extend the schema's semantics.

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 clearly states the operation ('List'), the resource ('fix tasks'), and the scope ('for a website'), and adds a specific detail about the included content ('fix and verification instructions'). This makes it immediately distinguishable from siblings like list_issues, get_fix_plan, and update_task_status.

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 implies the tool is used when you need fix tasks for a site, but it does not explicitly state when to use it instead of related tools such as get_fix_plan or list_issues. There are no exclusions or alternative routing hints, so the agent must infer usage context from the name and resource type.

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