project_get_about

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description usefully adds what the response contains (supported API versions, latest version), but then spends most of its length on version-parameter policy that does not apply to this parameterless tool.

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?

The first sentence is front-loaded and useful, but the remaining three sentences are boilerplate about API version pinning plus a raw URL example for a different path — content that does not earn its place in a parameterless 'about' call.

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 simple zero-parameter read with full annotation coverage, the description does state what the payload covers, which is the main thing an agent needs. However, it omits any statement of whether version negotiation is automatic and leaves the reader unsure whether a parameter is expected, which undermines a call that should be trivially complete.

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?

Zero parameters normally earns the baseline 4, but the description repeatedly references a 'version parameter' and shows an apiVersion query-string example for a different endpoint, implying a parameter that does not exist in the schema. That is misleading rather than additive, so it drops below baseline.

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?

The description names a specific HTTP resource (GET /project-service/api/about) and states what the page contains: supported API versions and the latest API version. It is clear what the tool does, but it does not distinguish itself from the many sibling 'get_about' tools (iaas_get_about, approvals_get_about, blueprint_get_about, content_get_about), which serve the same purpose for other services.

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 guidance on when to call this versus the other *_get_about siblings. The only usage advice given — 'The version parameter is optional but highly recommended' — is inapplicable because the tool takes no parameters, so the guidance actively misdirects rather than helping an agent choose.

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