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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds context beyond that: the result set is deliberately shallow (ids, titles, links only), so an agent knows full request bodies require a separate id-based lookup. Missing only operational details such as result limits, recency window, or pagination.

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?

Two sentences, front-loaded with the verb and scope, with zero filler. The second sentence earns its place by flagging the shallow return shape and the id-based path to details.

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?

The tool is simple (one required string parameter) and an output schema exists, so return values need not be spelled out here. The description covers purpose, scope, and the natural next step, but leaves ambiguity against a near-identically named sibling search tool.

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 100% and the single parameter is fully documented as 'The service in plain words'. The description adds a small amount of framing ('for a freelance or agency service', 'recent public'), but nothing about query syntax, matching behavior, or free-text expectations. This is the baseline case where the schema does the work.

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?

States a specific verb and resource ('Search recent public hiring requests') plus the domain ('for a freelance or agency service'), which tells the agent what it will get back. It does not differentiate itself from the similarly named sibling find_hiring_requests, leaving the agent to guess which search entry point applies.

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?

Usage is only implied by the scope words 'recent public'; there is no explicit statement of when to use this versus find_hiring_requests or the other search-like siblings. The one routing hint present is the follow-up path: details of a single request are retrieved by its id rather than through this tool.

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