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

Goes well past the annotations by describing the refusal path (resume rejected when a connection needs re-auth or the plan has no room) and instructing the agent to relay that refusal verbatim. Also clarifies that pause is non-destructive, which meaningfully refines the blunt destructiveHint=true flag without contradicting it.

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?

Front-loads the resource and the trigger phrase, and every sentence carries operational content. The nested parentheses make a couple of sentences denser than necessary, but nothing is filler.

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, so return values need no explanation; the description spends its space on what the agent must do (confirm, look up id, relay refusals) instead. Nothing needed to call this two-parameter mutation 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?

Schema coverage is 100%, so the 3 baseline applies, but the description adds real semantic weight to `status` by explaining that resuming also switches on a draft once the account has a plan — something the enum text does not say. It also reinforces the id's provenance from list_integrations.

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?

Names the resource (integrations between two systems) and the two concrete actions (pause: nothing syncs, nothing deleted; resume: status active, which also activates a draft when a plan exists). A reader can distinguish it from set_automation_status and from deletion, which the description explicitly says happens elsewhere.

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?

States the caller condition (a signed-in CRM Connector customer wants a pause or resume), an explicit prerequisite flow (confirm first, get the id from list_integrations), and an explicit exclusion (permanent removal happens on the integration's page in CRM Connector). This is when/when-not/alternative coverage in four sentences.

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