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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds nothing beyond that: no error behavior for a missing or invalid project id, no note on what a project contains, no hint about the return payload.

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 words are technically waste-free but represent under-specification rather than conciseness. There is no front-loaded statement of what the tool actually does, so brevity here works against the agent.

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?

This is a simple single-parameter read tool with a fully documented schema and annotations covering safety, so little is strictly required. Still, the description gives no sense of what a project object is or how the lookup behaves when the id is unknown, leaving a thin but tolerable gap.

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% with a single clearly documented projectId field (format p_…), so the schema does the heavy lifting. The description contributes no additional meaning about the parameter, which matches the baseline 3 for fully covered schemas.

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?

"One project." merely restates the name and title in fragment form; it never states a verb (retrieve/fetch) or that it takes a single project identifier. It implies singularity, which is a small distinction from a list tool, but no explicit resource description is given.

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?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives. An agent must infer entirely on its own whether to call this versus a listing tool or a sibling such as get_workspace.

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