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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so safety is covered structurally. The description adds genuine value by specifying that only 'public' requests are exposed and by naming the returned attributes, though it says nothing about failure modes or access constraints for private requests.

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 compact sentence with the resource and the returned attributes front-loaded and no filler. Nothing could be removed without losing information.

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?

With one documented parameter, rich annotations, and an output schema carrying the return shape, the description covers what an agent needs to invoke it. Minor gap: it doesn't explain what happens when the id is unknown or belongs to a non-public request.

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?

There is a single required parameter with 100% schema description coverage, so the schema already explains that 'id' is an id returned by search. The description restates the id-based lookup but adds no format, length, or validity detail beyond the schema; baseline 3 applies.

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 states a specific verb+resource: it returns details of exactly one public hiring request, identified by id, and enumerates the fields returned (type, budget, platform, community, age). The generic tool name 'fetch' relies on the title and this sentence for meaning, and it never distinguishes itself from siblings like find_hiring_requests or search.

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?

'By its id' implies the id comes from a prior lookup (the schema says 'An id returned by search'), so a single-record retrieval workflow is implied. However, there is no explicit when-to-use vs. find_hiring_requests, no stated behavior for missing/unknown ids, and no note about whether a datastore connection is required.

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