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

Annotations already cover the safe-read profile (readOnlyHint=true, openWorldHint=false, destructiveHint=false), so the description doesn't need to restate safety. It adds real context beyond that: the shape of each result (id + parent job family), how callers should use that id downstream, and the no-match behavior. It doesn't mention result limits or ordering, which would make it a 5.

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?

Front-loaded with the core action, then result shape, then the tuning flag, then the fallback — a logical order with no wasted sentences. The trailing 'REQUIRED arguments: searchText' line is redundant with the schema and costs it a point, as does the slightly nested parenthetical about jobTitleIds.

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 no output schema, the description carries the burden of explaining returns, and it does name the two fields that matter (id and parent job family). For a 3-parameter read tool with full schema coverage and clear annotations, this is close to complete; only the remaining result fields and ordering/limit behavior are unstated.

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%, so limit, searchText, and excludeFamilyLikeTitles are all documented in the schema. The description reinforces the exclusion flag's intent and the 'REQUIRED arguments: searchText' note, but that largely repeats the schema's required array rather than adding new semantics. 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?

Specific verb+resource ('Search specific job titles by name') that immediately distinguishes it from siblings like search-jobs and search-job-families. It also explains what the result is for: the id is the titleId consumed by the benchmark tools' jobTitleIds filter, so an agent knows exactly which tool family this feeds.

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?

Explicit usage: use this to narrow a benchmark query to an exact title within a job family, plus a named fallback ('If this returns no matches, fall back to search-all, which... applies a fuzzy fallback'). It also states when to set excludeFamilyLikeTitles, so both the happy path and the failure path are covered.

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