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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered structurally. The description adds some value by making the consequence explicit (permanent removal plus termination of all future scheduled runs), but it says nothing about required permissions, confirmation flow, or behavior when the taskId does not exist.

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 compact sentence with zero filler, front-loading the destructive nature and the resource in the first few words.

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 destructive delete with annotations covering safety and no output schema, the description conveys enough to call it correctly; only permission/error-context detail is absent, which is minor here.

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?

Only one parameter, taskId, and schema description coverage is 0% – the schema supplies type/format/pattern but no prose meaning. The description never mentions taskId at all, though its name and UUID constraint make it largely self-evident, so the gap is small rather than severe.

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?

Specific verb+resource: "Permanently delete a scheduled Replo task" tells the agent exactly what entity is affected and that it is the Replo task resource (paired with get_task/list_tasks). It does not, however, explicitly differentiate itself from other delete-style siblings such as delete_site_page or sightglass_delete_board.

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 when-to-use guidance, no stated prerequisites, and no mention of alternatives (e.g., pausing a task versus deleting it). The agent must infer that this is the correct tool purely from the resource noun.

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