docs_read

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

With no annotations, the description alone must carry the safety profile: 'Read' and 'text content' imply a non-destructive operation and signal that formatting/structure is not returned, which is useful. However, it doesn't address permission or auth requirements, return value shape, behavior on missing/inaccessible documents, or size limits.

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?

One sentence with no waste, front-loaded with the verb and the resource. Nothing could be cut without losing meaning.

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 simple single-parameter read tool with a fully documented schema and no output schema requirement, this is close to sufficient: the agent knows what it does and what it needs. The remaining lack is behavioral detail (permissions, empty-doc behavior, what 'text content' excludes).

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 required parameter (documentId), so the schema already carries the parameter meaning. The description adds nothing beyond it, which is the baseline-3 case rather than a strength.

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 ('Read') and a specific resource ('text content of a Google Docs document'), clearly separable from the sibling mutation tools docs_create and docs_append. It stops short of explicitly naming the read-alternative siblings, but the operation is unambiguous.

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?

No guidance on when to use this versus the sibling tools; an agent must infer that this is the read path while docs_create/docs_append are the write paths. There are no prerequisites, no exclusions, and no mention of what to do when the document is large or empty.

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