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

Adds real behavior beyond the readOnly/idempotent annotations: 404 for private or withdrawn bases, no cached files served post-withdrawal, and an untrusted-data security warning. The iframe and 3–160 character / 20-result details belong to the search routes rather than this index read, creating minor noise.

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?

Purpose is front-loaded, but the description drifts into search-route limits (3–160 characters, 20 results per page) that don't apply to reading a root index. Several sentences serve adjacent tools rather than this one.

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 single-parameter read with no output schema, it covers availability semantics (404, no stale cache), authentication (none needed), and a prompt-injection caution. Only the mis-scoped search details and lack of alternative routing keep it from full marks.

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 base_id is fully described there as the 64-character ID. The description adds no syntax, format, or constraint details for base_id, 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?

Specific verb+resource: 'Read the published OKF root index' with a clear scope ('Published bases only'). It is distinguishable from siblings like public_get_base and public_read_base_document, though it never names an alternative to contrast against.

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 conditions ('Published bases only. No account required') and describes the embedding scenario, but never states when to choose this tool over public_get_base or public_list_bases, which are the closest siblings. Usage is implied rather than routed.

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