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

Annotations already mark it read-only, idempotent, open-world, and non-destructive. The description adds useful return-field context (raw source cells, source URL, published period, collection time, entity matches, preserved revisions) and a critical semantic caveat about missing data not implying withdrawal.

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 purpose and return payload; the second sentence is a useful caveat rather than filler. The first sentence is dense but well structured.

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?

No output schema exists, so the description rightly summarizes return fields, and annotations cover the safety profile. However, with three parameters and zero schema descriptions, pagination behavior and output structure remain under-explained.

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 0%; the description clarifies only id as a POWER project ID from power.board. It does not explain limit or offset pagination, defaults, or max values, leaving two parameters undocumented.

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 'Read one POWER project ID from power.board' — a specific verb and resource — and enumerates the returned evidence fields. It does not explicitly differentiate itself from siblings like power.history or power.coverage, but the core purpose is clear.

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 when-to-use or when-not-to-use guidance is provided, and it never names alternatives such as power.board, power.history, or power.coverage. The only constraint is interpretive: missing from a later file does not establish withdrawal.

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