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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so safety is covered. The description adds one genuinely non-obvious behavior — that the response bundles up to 3 similar open jobs — but says nothing about error/not-found behavior or what happens for closed or expired jobs.

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?

A single well-formed sentence with the retrieval key and return contents front-loaded; no filler or redundancy. It is perhaps a touch terse for a tool whose return shape is undocumented.

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?

There is no output schema, so the description must sketch the return value; it does so only loosely ('full details', 'up to 3 related open jobs') without naming fields or format. Adequate for selecting the tool, thin for interpreting its output.

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?

Only one parameter and schema description coverage is 0%, so the description is the sole source of meaning. It clarifies the ID is a CafeDev-specific job identifier, but adds no format, length (maxLength 64), or example beyond that.

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 (Get) and resource (job) with the identifying key (CafeDev ID) and even previews the payload ('full details ... including up to 3 related open jobs'). It is clearly distinguishable from list_companies/search_jobs in intent, though it never explicitly names those siblings.

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: the agent must already hold a specific job ID to call this, and the 'open job' qualifier hints that only open postings are retrievable. No alternatives (e.g. search_jobs) or when-not-to-use conditions are stated.

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