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

The description explains the main behavior (fetches, enriches, returns) but does not address the annotations: readOnlyHint=false suggests potential side effects, yet no writes are mentioned. The description should clarify if any state is modified (e.g., logging the check). Without that, there is ambiguity.

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 sentence of 20 words that succinctly conveys the action and output. Every word is necessary; no redundancy. It is front-loaded with the tool's purpose.

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 parameterless tool with no output schema, the description adequately covers what the tool does. However, it could mention the output format (e.g., what the 'prioritized summary' looks like) or any prerequisites (e.g., authentication). Given the simplicity, it is nearly complete.

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?

There are no parameters, so the schema coverage is 100% (empty). The description adds no parameter info, but given zero parameters, a baseline of 4 is appropriate. The tool effectively requires no input, which is clear.

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 tool's purpose: performing a daily PR monitoring check. It specifies the actions (fetching open PRs, enriching with CI status, reviews, conflicts, and returning a prioritized summary), which is specific and well-scoped. The verb 'Run' and resource 'daily PR monitoring check' are distinct from sibling tools like 'check-setup' or '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 usage context is implied by the name and description: it's meant for daily PR monitoring. However, it does not explicitly state when to use this tool versus alternatives (e.g., 'status' for overall status, or 'search' for custom queries). No exclusions or prerequisites are mentioned.

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