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

Annotations already declare readOnlyHint, openWorldHint=false, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds that results come with benchmarks and that `full_name` feeds other tools, though it does not describe result ordering or pagination.

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?

Two sentences, with the purpose and starting-point instruction front-loaded, and no redundant wording. Every sentence adds useful 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 two-parameter, read-only list tool with complete schema descriptions and annotations covering safety, the description gives enough workflow context. It could mention result ordering or pagination, but that is a minor gap and there is no output schema.

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 `query` and `with_benchmarks` are fully documented in the schema. The description alludes to benchmarks but does not add meaning beyond what the schema already provides for either parameter.

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 (List) and resource (repositories with the hotpath GitHub App installed), and mentions that benchmarks are included. The 'Start here' framing helps distinguish it as the entry point, but it does not explicitly contrast itself with sibling list tools such as list_benchmarks or list_reports.

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?

Explicitly says to start here and explains that `full_name` is the `repo` argument used by the other tools, which gives clear ordering relative to siblings. It omits when-not-to-use conditions, but for a list entry point that is a minor gap.

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