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

No annotations provided, so description carries the burden. It discloses a connectivity check via GET /v1/logs and that it returns project scope, implying a read-only operation. It also notes the absence of a user-session API. It does not detail error behavior or side effects, but for a simple GET that is acceptable.

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?

Single sentence, front-loaded with the core purpose ('Returns the project scope'), and includes only necessary context about the connectivity check and lack of an alternative API. No wasted words.

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?

Tool is simple with no parameters, but the description does not specify the exact structure of the returned project scope (e.g., string vs object) nor any error conditions. Given no output schema, this leaves ambiguity about the return value, making it incomplete for an agent that needs to interpret the result.

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?

Tool has zero parameters and schema coverage is 100% (vacuously). Baseline is 4 for zero-param tools. The description explains the tool's purpose and what it returns, which is sufficient given no parameters to document.

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?

Description states a specific verb 'returns' and resource 'project scope', and clearly distinguishes from sibling log tools (logs_get, logs_ingest, logs_search) by being about project scope rather than log operations. The title 'Current project scope' reinforces the purpose.

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?

Implies usage by noting 'There is no user-session projects API', indicating this is the only way to get project scope. It does not explicitly list alternatives or when-not-to-use, but the distinction from siblings is obvious from the name and purpose.

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