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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is covered. The description adds genuine context beyond that: it costs nothing ('No generation or charge') and it reads the same references/library state the studio uses, which matters for trust in the result.

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?

Three short sentences, front-loaded with the purpose. However, the trailing 'Arguments: {"path": {"id": ...}}' restates the schema structure rather than adding meaning, spending words on redundant structure.

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, closed-world lookup with one parameter and no output schema, the description conveys the purpose and cost but leaves the returned structure (what 'required/conditional/optional' looks like) and the id's origin unspecified. Adequate but with clear gaps given 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 0% and the single nested parameter is documented only as 'id: string'. The description compensates partially by clarifying the id is a project id and showing the nesting, but it gives no format or how to obtain the id.

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 (Read) and resource (required, conditional and optional inputs plus the exact questions to ask), which is concrete enough to distinguish it from generation tools like kelpo_generate. It never names a sibling alternative, so differentiation is implied rather than stated.

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?

'Uses the same selected references and library as the studio' and 'No generation or charge' imply this is a pre-flight lookup that costs nothing, which is useful context for choosing it. But there is no explicit when-to-use versus when-not, and no named alternative among the many siblings.

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