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

Annotations already declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false, so the safety profile is covered by structured data. The description adds context beyond that: no API key or auth is required, and the response is scoped to bundled local data with source-file hashes and retrieval dates, which signals reproducibility. It stops short of noting caching, cost, or freshness caveats.

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?

Three short sentences, purpose front-loaded, zero preamble. The enumeration of returned fields (year, release, source files, hashes, retrieval date, row counts) is somewhat redundant with the existing output schema and is the one part that does not fully earn its space.

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 zero-parameter, read-only introspection tool with an output schema already defining the return shape, this is essentially complete: what it reports, where it comes from, and that no credentials are needed. The only gap is the absence of any guidance on when to prefer it over detect_latest_year.

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?

The tool takes zero parameters, so the baseline is 4; there is nothing for the description to disambiguate. It correctly spends no words on argument semantics and instead covers the response surface.

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: reports which OEWS release the server answers from plus provenance (source files, SHA-256, retrieval date, row counts). Clear enough to separate it from data-retrieval siblings like get_wage_data or compare_metros. It never names detect_latest_year, the sibling most likely to be confused with it, so an agent must infer the distinction.

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: an agent can infer this is the provenance/audit call, and the 'No API key is used or needed' line hints at a cheap pre-flight check. There is no explicit when-to-use, when-not, or pointer to any alternative such as detect_latest_year for upstream release checking.

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