Get a CLI auth challenge

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

The description adds that it's a GET operation (safe) and 'Authorization class: public' (no auth needed), which supplements the annotations. No contradictions, but does not describe other behavioral aspects.

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?

Very concise: two sentences with no wasted words. The first sentence is redundant with the title, but the structure is efficient.

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 read tool with annotations, the description provides the endpoint and auth class. However, it lacks parameter explanation and usage context, leaving gaps for a complete understanding.

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 coverage is 0% (no parameter descriptions). The description mentions the endpoint path with {id} but does not explain what the 'id' parameter represents, leaving the agent to infer its meaning.

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 clearly states 'Get a CLI auth challenge' with the HTTP method and endpoint, distinguishing it from sibling tools that create, approve, or cancel challenges. However, it adds little beyond the title and endpoint.

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 guidance on when to use this tool versus alternatives like pc_post_cli_auth_challenges, pc_post_cli_auth_challenges_by_id_approve, etc. The description lacks explicit usage context.

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