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

Goes well beyond the readOnly/idempotent/non-destructive annotations by disclosing that every read re-checks publication, that private or withdrawn bases return 404, and that no cached files are served post-withdrawal. The untrusted-text security warning is a valuable addition. However, a chunk of the text describes the embed iframe route (search length limits, 20 results/page) rather than this export tool, which dilutes the relevant behavioral signal.

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 core sentences (ZIP download, published-only, 404 on withdrawal) are front-loaded and earn their place. But the iframe/embed and search-limit sentences concern the embedding route rather than this export call, so they are tangential padding for this definition.

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 still conveys that the result is a ZIP download and explains the publication/404 semantics an agent needs. Minor gaps remain: nothing about archive contents or whether the download is streamed vs. URL-returned, but the essential calling conditions 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% for the single base_id parameter, and the schema already documents its 64-character ID format. The description adds nothing about the parameter, so the 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 and resource: 'Get the published OKF ZIP download.' That distinguishes it from sibling metadata readers like public_get_base and public_read_base_* by naming the downloadable artifact. It never explicitly contrasts with those siblings, though the resource is distinctive enough to sort.

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?

Gives preconditions ('Published bases only. No account required.') but no explicit when-to-use-vs-alternative guidance, e.g. it never says to call public_get_base first for metadata or which sibling to prefer for reading documents. The iframe/embed note is context, not selection guidance for this tool.

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