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

With no annotations provided, the description carries full burden for behavioral disclosure. It states this is an update operation (implying mutation) but doesn't disclose important behavioral traits: whether this requires specific permissions, if changes are reversible, what happens to other bucket settings not mentioned, rate limits, or error conditions. The description only covers the basic action without the operational context needed for safe use.

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 description is appropriately sized and front-loaded with the core purpose in the first sentence. The Args section is structured but could be more integrated. There's minimal waste, though the formatting with separate 'Args:' section creates some structural separation that isn't ideal. Every sentence earns its place by providing necessary parameter 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?

Given this is a mutation tool with no annotations, 3 parameters, 0% schema coverage, but with an output schema present, the description is moderately complete. The output schema existence means return values don't need explanation in the description. However, for a configuration update tool affecting cloud storage, the description lacks important context about side effects, permission requirements, and what constitutes valid updates. It's adequate but has clear gaps for safe operation.

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 0%, so the description must compensate. It provides basic semantic meaning for all three parameters: tenant_id ('The tenant ID containing the bucket'), name ('The bucket name to update'), and versioning ('Enable or disable versioning'). However, it doesn't explain parameter interactions, format requirements (e.g., bucket naming rules), or what 'optional' means for versioning (default behavior, null handling). The description adds value but doesn't fully compensate for the schema coverage gap.

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 description clearly states the verb ('Update') and resource ('S3 bucket configuration'), making the purpose immediately understandable. It distinguishes from siblings like bucket_create, bucket_delete, and bucket_get by specifying it's for updating existing buckets rather than creating, deleting, or retrieving them. However, it doesn't fully differentiate from database_update or service_update which perform similar update operations on different resources.

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?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., bucket must exist), when not to use it, or clarify relationships with sibling tools like bucket_get (to check current configuration) or bucket_delete (for removal). The agent must infer usage context from the tool name alone.

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