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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint, so the safety profile is covered. The description adds only that the result is a 'readable document,' with no details on formatting, size limits, or error behavior – modest added context.

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 front-loaded sentence that conveys scope and output form with no filler.

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?

For a one-parameter read tool with an output schema and full annotations, most burdens are handled elsewhere. However, the description omits sibling differentiation against get_job, which is a notable gap given the near-identical names.

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 100%, so the id parameter and its origin ('from search') are fully documented in the schema. The description adds no syntax or format details beyond the schema's baseline.

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 ('Fetch'), resource ('one job by its id'), and output form ('full text ... as a readable document'). Distinguishes from siblings like search by emphasizing retrieval of a single job's full content rather than listing or searching.

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?

It implies usage by mentioning 'from search' but offers no explicit when-to-use guidance, and it does not mention the sibling get_job or how fetch differs from it despite the overlapping purpose, leaving routing ambiguous.

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

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

The annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false, and destructiveHint=false, so the safety and side-effect profile is fully covered. The description adds helpful context about what the tool returns (categories and roles, with typical job titles) and its relationship to search_jobs, but it does not go beyond the annotations to describe any additional behavioral traits like rate limits or specific output details.

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 extremely concise, two sentences, and front-loads the core purpose. Every sentence earns its place by clarifying what the tool returns and its connection to search_jobs without any filler.

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?

Given that the tool has an output schema and rich annotations, the description is nearly complete. It explains the tool's role and return values well. It could be slightly more complete by explicitly mentioning the default behavior (listing all categories when no category is provided) and possibly the format of keys, but the essentials are covered.

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 100%, so the schema already explains the single parameter 'category' as a key to list its roles in detail. The description adds meaning by noting that passing a category key returns its roles with typical job titles, and that omitting it gives the top-level categories. This is slightly more context than the schema, but not substantially beyond what's structured; it meets the baseline for high schema coverage.

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 provides a specific verb+resource: it tells the agent this tool lists occupation categories and their roles. It also explicitly differentiates from the sibling search_jobs by stating these categories and roles are meant to be used as filters for that tool. This gives an unambiguous sense of purpose.

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 gives a clear use case (to get category and role filters for search_jobs), implying when to use it. However, it does not explicitly state when *not* to use it, or contrast it with other siblings like fetch or search. It also doesn't mention whether calling it without a category is the standard way to list all categories.

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

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description usefully adds the corpus scope (only open jobs, Switzerland only), but the return-field detail duplicates the output schema, so the net added behavioral value is modest.

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, no filler, with the core purpose front-loaded and the alternative relegated to second position. Every clause earns its place.

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?

For a one-parameter read tool with an output schema and rich annotations, the description covers purpose, scope, and the sibling alternative adequately. Usage nuance is the only thin spot, and the output schema removes any need to explain return values.

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 coverage is 100%, with the schema itself supplying the example format ("Pflegefachfrau Bern"). The description adds no syntax, format, or constraint detail beyond the schema, so 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?

States a specific verb (keyword search), resource (open jobs), and scope (Switzerland), plus the return shape. It explicitly differentiates itself from the sibling search_jobs, so an agent can choose between them without opening a schema.

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?

"search_jobs offers filters and more fields" names the alternative and implies this tool is the simple keyword path, which is clear selection guidance. It stops short of stating explicit when-not conditions (e.g. use this only when no filters are needed), so it is not a full 5.

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