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

Annotations already show readOnlyHint=true, so the agent knows this is a safe read. The description adds value by listing the fields returned (title, company, location, posting URL, description), providing behavioral specifics beyond annotations without contradiction.

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?

The description is a single sentence, 14 words, with the verb and key action front-loaded. Every word serves a purpose, and there is no redundant or filler content.

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 only one parameter and no output schema, the description adequately covers what the tool does and what it returns. It does not mention error handling or slug existence, but for a simple fetch-by-id tool, this is sufficient and not a significant gap.

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 already describes the slug parameter as 'The job's public slug (from search or facets results).' The description merely repeats 'by slug' without adding any new semantic detail, so baseline 3 is appropriate.

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 clearly uses 'Fetch' as the verb, specifies the resource as 'a single job', and identifies the key identifier 'slug'. It also enumerates the returned content fields, distinguishing this from sibling tools like 'search' which return lists, and 'apply', 'save', etc. which perform other actions.

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?

The description implies usage when a slug is available (e.g., from search or facets results) and provides clear context for retrieving full job details. However, it does not explicitly state when not to use this tool or name alternatives, leaving some room for inference.

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