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

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description usefully adds that a prior revision is being superseded ('rollback'), but never says what happens to the previously active revision or whether the change can be undone — the main behavioral question for an activation tool.

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 front-loaded sentence with zero filler; the core action leads and the qualifier follows. Nothing to trim.

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?

With only two well-documented required parameters, no nested objects, no output schema, and annotations covering idempotency and safety, very little is left for the description to carry. The one remaining gap is the side effect on the previously active revision.

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%, and the schema already explains both path_key and revision (including that the revision number comes from list_escalation_path_revisions). The description adds nothing about parameter format or validation, so the baseline of 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 ('Make ... the active one') and resource ('escalation path revision'), and the parenthetical clarifies the two scenarios it covers: rollback and draft activation. It cleanly distinguishes this resource's revision-activation from the many activate_*_revision siblings, though it doesn't explicitly name an alternative tool.

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?

'a rollback, or activating a draft' implies when the tool is appropriate, but there is no explicit when-not guidance, no mention of prerequisites (e.g. revision must exist / come from list_escalation_path_revisions), and no indication of what to use instead for other lifecycle actions.

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