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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint, so safety is covered. The description adds the constraint on ID provenance, which is useful behavioral context, but doesn't disclose return format or whether report_limit affects pagination behavior beyond the schema.

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, front-loaded with the purpose then the ID-provenance constraint. Efficient, with no wasted clauses, though purpose and constraint could be even tighter.

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?

Given annotations cover safety and the schema covers parameters, the description is complete enough to invoke correctly: an agent knows what it returns, which ID to use, and where to get it. No output schema exists, but the description enumerates return contents well enough.

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 both parameters are already documented in the schema. The description reinforces the public_id provenance rule but adds no syntax or format detail beyond what the schema provides; baseline 3 is appropriate.

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 clear verb (Get) and enumerates the returned resources (timeline, latest development, digest, related events) for one public story. It doesn't explicitly contrast with siblings like gameshot_get_latest or gameshot_get_hot_topics, but the phrase 'for one public story' implicitly distinguishes it from the list-oriented siblings.

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?

Clear precondition: only pass a public_id obtained from gameshot_get_hot_topics links.story. It doesn't state when NOT to use it versus alternatives like gameshot_search or gameshot_get_latest, so no explicit exclusion, but the sourcing requirement is a strong context cue.

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