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

Annotations already declare readOnlyHint=false, destructiveHint=false, and idempotentHint=true, so the safety profile is partly covered. The description adds genuinely useful context beyond that: revisions are retained and the policy can be activated later, confirming the operation is reversible rather than a hard delete. No permissions or error behavior is described, keeping it out of the 5 range.

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 with the core action front-loaded and no redundant restatement of the name or schema. Every clause carries distinct information (the routing effect, then the revision retention).

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 tool with no output schema and annotations covering the safety profile, the description supplies the two things an agent most needs: what changes operationally and that the change is recoverable. Nothing required to call it correctly 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?

There is a single parameter with 100% schema description coverage, and the schema already tells the agent that team_id comes from list_teams. The description refers to 'a team's escalation policy' but adds no format, source, or constraint detail beyond the schema, 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?

The description gives a specific verb and resource ('Deactivate a team's escalation policy') and explains the operational effect — restoring team-level fan-out routing. It implicitly distinguishes itself from update_team_escalation_policy and activate_team_escalation_policy_revision by noting that revisions survive and can be reactivated, but it never names those alternatives outright.

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 only implied: the reader infers you archive when you want to revert to default team-level routing rather than reconfigure the policy. There is no explicit when-to-use, when-not-to-use, or named alternative (e.g., why archive instead of update, or how this relates to activate_team_escalation_policy_revision).

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