Delete an action from a automation

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 contributes the required permission (manage_automations), which is genuinely additive, but it never mentions the confirm="YES"/dry_run safety gate that governs actual execution, nor whether deletion is reversible.

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?

The first two sentences say the same thing twice ('Delete an action from a automation' / 'Deletes a specified action from a scheduled automation'), wasting the most prominent position on a restatement of the title. The permission line does earn 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?

An output schema exists and the input schema is fully described, so the mechanical call requirements are covered. However, for a destructive tool with a mandatory confirmation string and a default-true dry_run, the description omits the operational flow that an agent most needs to avoid accidental deletion.

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%, so all five parameters including confirm and dry_run are already documented in the schema. The description adds no syntax, default, or interaction detail 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 an action) scoped to a scheduled automation, which distinguishes it from delete_automation and delete_package_version_action in the sibling list. It stops short of explicitly naming those siblings, so differentiation is inferential rather than stated.

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 guidance on when to use this versus deleting the whole automation or other delete-* tools, and no mention of prerequisites beyond the permission string. The agent must infer the use case entirely from the name.

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