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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description still adds real context beyond them: the call is free, it takes no input, and the payload bundles plan-level metadata (the Autopilot limit) alongside the channel list. It does not discuss result ordering or empty-state behavior.

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?

Two sentences, front-loaded with the returned fields and closed with the cost/safety note, with no filler. The first sentence is a long run-on clause chain ('format, niche and Autopilot: on or off, the days and hour...'), which slightly hurts scanability. Nothing is redundant enough to cut outright.

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?

With no output schema and no parameters, the description carries the return-value burden and discharges it by listing the salient fields plus the plan-level Autopilot limit. An agent knows what it will receive and that the call is free and read-only. It omits finer structure, such as whether channels come as an array or how the limit is represented, which would matter for parsing.

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 tool takes zero parameters, which sets the baseline at 4, but the description is scored here for added meaning rather than parameter explanation, and it says nothing about inputs because there are none to explain. Its content is entirely about outputs, which is better credited under purpose and completeness. The empty schema is fully self-documenting.

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 names the resource (the user's ClipFlux channels) and enumerates what comes back: format, niche, Autopilot state, schedule days/hour, posting destination, credit floor, plus the plan's Autopilot channel limit. That is specific enough to separate it from siblings like list_accounts, list_looks or create_channel. It stops short of a crisp leading verb such as 'List', relying on the title and name for the action.

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?

Usage is only implied: an agent infers this is the read path for inspecting channels and the Autopilot cap, but the description never states when to call it versus set_autopilot or create_channel, nor any precondition. The 'Free, read only' note hints at cost and safety but is not framed as a selection rule. No exclusions or alternatives are offered.

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