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

Annotations already declare destructiveHint=true and idempotentHint=false, so the safety bar is lower, yet the description still adds real value: the blast radius ("stop it for everyone enrolled"), irreversibility ("Cannot be undone"), and a required human-confirmation step. It does not mention permissions or what happens to enrollment history after deletion, but the added context is substantive.

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 short sentences, zero waste, with the destructive scope front-loaded before the irreversible/consequence warning. Every clause earns its place.

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 deletion tool with full annotation coverage and no output schema, the description supplies the blast radius, irreversibility, and confirmation requirement an agent needs before invoking. Only the routing versus pause_sequence 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 description coverage is 100%, with sequenceId and idempotencyKey both fully documented in the schema (including the retry semantics of the idempotency key). The description adds no parameter-level meaning beyond that, so the baseline 3 applies.

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 a drip sequence") and adds the important scope detail that it stops the sequence for everyone enrolled. It does not explicitly contrast itself with pause_sequence or deactivate_sequence-style siblings, so the agent must infer the permanence distinction from "Cannot be undone" rather than being routed directly.

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 implied rather than explained: "confirm with the user first" sets a required interaction precondition, and "Cannot be undone" signals this is for permanent removal. However, it never names the alternative (pause_sequence) or states when deletion is appropriate versus pausing.

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