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

Discloses key behavior: pauses the run and records the need. But no annotations exist, and description omits side effects, reversibility, or post-pause state.

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?

One sentence of 15 words, front-loaded with verb and resource, 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?

Adequate for a simple two-param tool, but missing context on how pausing works, how to resume, and what the recorded need entails. No output schema, so return value is undefined.

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?

0% schema description coverage, yet description only hints at 'need' parameter (e.g., missing access/resource) and fails to explain 'run_id'. Does not sufficiently compensate for schema gaps.

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 clearly states verb 'Report' and resource 'blocking need', with an example. It differentiates from siblings by specifying 'pauses the run', but could be more precise about what constitutes a blocking need.

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 for blocking issues, but no explicit when-to-use or alternatives among siblings. No guidance on prerequisites or when not to use.

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