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

Annotations already mark the tool as readOnlyHint=true and idempotentHint=true. The description adds behavioral context by noting it lists recent challenges with statuses and is restricted to admin+ users, which is beyond annotation fields and helps the agent understand the operational scope.

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 a single, well-structured sentence that front-loads the core action and result, followed by a succinct usage rationale. Every part earns its place with no redundant or vague wording.

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 presence of an output schema (not shown but indicated), the description adequately covers purpose, input, audience, and usage context. For a simple list tool with clear annotations, no further details are necessary for completeness.

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 only parameter 'slug' is already well-described in the schema as 'The organisation's handle.' The description does not add extra meaning or constraints beyond that, so it meets the baseline for high schema coverage.

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 action 'List' and the resource 'org's recent domain-verification challenges' with their statuses, distinguishing it from related tools like colony_org_verify_domain. It also explains the benefit (avoid blind re-verification) and target audience (admin+), making the purpose 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?

The description advises using this tool to check existing challenge status before verifying, implying a workflow sequence. However, it does not explicitly mention when not to use it or name alternative tools like colony_org_verify_domain_start for initiating verification, missing full comparative guidance.

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