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

Annotations already declare read-only, idempotent, non-destructive, closed-world behavior. The description adds that it returns the input schema, limits, and examples, which is behavioral context beyond the hints. It doesn't mention auth or rate limits, but for a safe read that is minor.

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 efficient sentence front-loads the return content and the lookup key. No waste, though it is terse enough to omit potentially useful qualifiers about id format or version defaults.

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?

Output schema exists, so return structure need not be explained, and the description correctly summarizes what it returns. However, with 0% schema coverage and no usage guidance, it should say more about how the id/version pair is consumed or when this tool is the right one among many catalog siblings.

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 0%, so the description must carry parameter meaning. It states the tool is identified 'by id and version', naming both required parameters, but gives no format, pattern, or version-semantics detail beyond the schema's own constraints. Marginal addition; baseline for two params with low coverage would be higher, but the description only names them.

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 verb (describe) and resource (one ComputeFirst catalog tool), and the title reinforces it. But it doesn't distinguish from sibling tools like search or activity, which might also surface tool info, leaving the agent to infer separation.

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 explicit when-to-use or when-not-to-use guidance. It doesn't say to use this before execute to inspect a tool, nor differentiate from search or list_saved_tools, so an agent has no routing cue.

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