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

Annotations only provide the generic safety profile (destructiveHint=true, readOnlyHint=false); the description goes far beyond that by spelling out the asymmetric semantics of true vs false, that existing accounts keep access after setting false, that future accounts inherit the setting, and that seat limits are unaffected. This is exactly the state-change detail an agent needs before invoking a destructive mutation.

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?

Dense but essentially fluff-free; the operator-only warning is front-loaded and each sentence carries operative detail. It is a single unbroken block rather than scannable segments, which slightly hurts readability for a description this long.

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?

There is no output schema, so the description carries the return-value burden and does so by describing the read mode's output (state plus used/limit seats and complimentary count). Combined with the mutation semantics and prerequisites, nothing an agent needs to call this correctly is missing.

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?

Schema coverage is 100%, so the baseline is 3, but the description adds real meaning: `teamId` and `email` are presented as interchangeable team identifiers, and `complimentary` is explained in terms of downstream account/seat effects rather than merely its type. It edges above baseline without being fully exhaustive about the read-mode return shape.

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?

Names a specific verb+resource combination ('reads or sets whether a CUSTOMER (team) is FREE') and anchors it to a concrete UI location (the Free switch beside Seats). It explicitly distinguishes itself from the nearest sibling, li_set_account_complimentary, so an agent can route correctly without opening either schema.

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?

Gives explicit when-to-use for both modes (set with `complimentary`, read by omitting it) and names the alternative tool for the per-account case. It also states the operator-only restriction up front, which is a hard gate on usage.

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