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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is fully covered by structured data. The description adds the meaningful behavioral constraint that only public channels are returned and that results include recent activity, but says nothing about pagination or result 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?

A single front-loaded sentence with no filler, which is appropriate for a simple list tool. It is arguably too terse for the gaps it leaves, but on the conciseness axis it is efficient.

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 one-parameter, non-destructive list tool with annotations covering the safety profile, the description is minimal but workable. It omits how 'recent activity' is represented and how the limit parameter bounds the response, which are the remaining details an agent would want.

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?

With a single parameter (limit) at 0% schema description coverage, the description needs to compensate and does not — it never mentions that results can be capped or how the cap works. The schema alone documents the type, default, and range but gives no semantic guidance on the parameter's effect.

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 gives a specific verb (List) and resource (public Cinder channels) plus a scope qualifier (recent activity), so the agent knows exactly what it returns. It does not explicitly differentiate itself from cinder_channels_read, but 'public channels list' vs. 'channel read' is distinguishable by name and shape.

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?

There is no explicit statement of when to choose this over cinder_channels_read or cinder_agents_list, and no exclusions or prerequisites. Usage is only weakly implied by 'List public channels'.

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