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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states this is an update operation, implying mutation, but doesn't cover critical aspects like required permissions, whether changes are reversible, error handling, rate limits, or authentication needs (e.g., the 'api_key' parameter). For a mutation tool with zero annotation coverage, this is a significant gap.

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 well-structured and appropriately sized. It front-loads the purpose, then uses clear sections (Args, Returns) to organize information. Every sentence earns its place, though the 'Returns' section is redundant given the presence of an output schema.

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 the tool's complexity (mutation with 3 parameters, nested objects) and no annotations, the description is partially complete. It covers the purpose and most parameters well, and an output schema exists, so return values don't need explanation. However, it lacks behavioral context (e.g., permissions, side effects) and misses one parameter ('api_key'), making it adequate but with clear gaps.

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?

The description adds substantial value beyond the input schema, which has 0% description coverage. It explains that 'id' is required and identifies the collection, and details the 'attributes' parameter with specific fields (name, description, private, tags, alt_names) and their types. However, it doesn't mention the 'api_key' parameter at all, leaving one of three parameters undocumented.

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 tool's purpose: 'Allows updating a collection's attributes (such as name or description)'. It specifies the verb ('updating') and resource ('collection's attributes'), and provides examples of attributes. However, it doesn't explicitly differentiate from sibling tools like 'update_iocs_in_collection' or 'create_collection', which would require a 5.

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, compare to sibling tools like 'create_collection' or 'update_iocs_in_collection', or specify scenarios for use. This leaves the agent without context for tool selection.

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