ghl_countdown_delete_timer

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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered; the description adds genuinely new behavior — that this is a SOFT delete, that timers are scoped to the token's location, and the required OAuth scope. It stops short of saying whether the timer can be restored or what state it ends up in.

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?

Front-loaded with purpose, then prerequisites, then endpoint and scope metadata in a scannable line-oriented layout. The 'COUNTDOWN TIMER API' banner and source-file citation are filler for an agent but small relative to the useful content.

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 single-parameter destructive tool with no output schema, the description covers auth requirements, the soft-delete semantics, and the exact endpoint. The only gap is the post-call state (does it return the deleted timer? is it recoverable?), which is minor for a delete operation.

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% and the single timerId parameter is fully described in the schema. The description adds only the endpoint path mapping ({timerId} in the URL) and the useful note that location scoping is implicit in the token rather than a parameter, which is a minor value-add beyond the baseline.

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?

States a specific verb and resource ('Delete Countdown Timer') and refines it as a 'Soft-delete', which separates it semantically from a hard delete. It does not explicitly name or route against siblings like ghl_countdown_get_timer or ghl_countdown_update_timer, though the name plus 'delete' makes the distinction fairly obvious.

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?

Prerequisites are given (sub-account/location token, countdown-timer/timer.write scope), but there is no statement of when to choose this over alternatives or when not to call it. The 'soft-delete' phrasing implies usage (removal that preserves data) but leaves that inference to the agent.

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