Behavior1/5

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

No behavioral information is disclosed beyond a generic 'approve' action. There are no annotations to compensate. The agent is left unaware of side effects, permissions required, or whether the approval is reversible.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise with a single sentence, but it lacks additional context that would be valuable for tool selection. It achieves brevity but at the expense of completeness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite having an output schema (not shown), the description fails to provide sufficient context for a simple mutation tool. It does not explain return values, error conditions, or how to interpret the output.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema adequately documents all parameters. The description adds no additional meaning beyond what the schema already provides, so the baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'approve' and the resource 'shared channel invite request'. However, it does not differentiate from the very similarly named sibling tool 'conversations_approve_shared_invite', leaving ambiguity about which tool to use for which scenario.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives like 'conversations_approve_shared_invite', 'conversations_decline_shared_invite', or 'conversations_request_shared_invite_deny'. The agent has no context to make an informed choice.

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