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

Annotations already declare readOnly=true, idempotent=true, openWorld=true, destructive=false, so safety is covered. The description adds content-scope hints (results, discovery paths, review history) but says nothing about pagination, result shape, or ordering beyond what annotations imply.

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 short sentences, front-loaded, but the second sentence ('Every usable API, browser or knowledge path can count') is cryptic and adds ambiguity rather than clarity. It neither earns its place nor harms the first sentence.

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 read-only list with full schema coverage and annotations covering safety, the description is minimally adequate but leaves key gaps: no return shape, no pagination, and no differentiation from capability_checks_get. It does not fully compensate for the missing 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 coverage is 100%, so both the company UUID and the environment enum are fully documented in the schema. The description adds no meaning beyond that, which is acceptable given full schema coverage.

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 names data categories (checklist, results, discovery paths, review history) but the verb 'Read the same ... shown in Summer' is self-referential and reads more like a single-resource fetch than a list. It does not distinguish this from the sibling summer_capability_checks_get, leaving the naming ambiguous.

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 on when to use this versus get, report, save, or test. There are no exclusions, prerequisites, or conditions stated. The agent must infer that this is a collection read purely from the 'list' suffix.

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