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

Annotations already declare readOnly/idempotent/non-destructive, and the description goes well beyond them: revocation effects on search/downloads, sharing propagation to current and future files, owner-only sharing changes, origin+CSRF requirements for the initial grant, org API key scoping, and 'private, no-store' responses. That is rich operational context an agent would not otherwise have.

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 single-sentence purpose is front-loaded, but the body is a dense block of sharing/revocation policy that reads partly like boilerplate for the team_* family and is not tightly scoped to reading a base. Several sentences could be trimmed without losing invocation-relevant information.

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 read-only tool with full annotation coverage, the description supplies the key missing behavioral context: the access model and auth requirements. It does not describe the return shape (no output schema exists) or pagination behavior beyond the schema cursor, but the core gaps 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%, including the cursor and organization_id semantics, so the schema already carries parameter meaning. The description adds no parameter-level detail (e.g., base_id format or cursor usage), making 3 the correct 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?

The opening sentence gives a concrete verb+resource ('Read your base and its documents'), which is better than a tautology. However, it never distinguishes this from near-identical siblings such as get_base, team_get_base_document, or team_list_bases, so an agent cannot tell from the text alone which team/personal variant to pick.

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?

There is no explicit when-to-use or when-not-to-use guidance, and no sibling is named as an alternative. The access-control narration implies a team-scoped read, but the agent must infer that this tool is the team variant versus get_base or the public_* equivalents.

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