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

The description does add genuinely useful behavioral context: external-system writes are not rolled back, and org-level MCP approvals plus business workflow approvals may gate the call. However, it describes creating a record that touches an external system, which conflicts with openWorldHint=false (and arguably destructiveHint=false), so the behavioral profile it paints diverges from the declared annotations.

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?

Three tight sentences with the core action front-loaded and no filler. The approval boilerplate is somewhat generic but still relevant to whether the call will succeed.

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 not be explained, and the non-rollback and approval caveats cover the main risks. Still missing for a mutating external-sync tool: confirmation that the quipassist connection must pre-exist, what a duplicate link does (idempotentHint=false), and any hint about the required field set.

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 0% and the single parameter is a nested object with siteId, name, city, state, address, and zipCode, none of which are explained in the schema. The description only says to 'review all transmitted fields' without identifying which fields are required (siteId, name) or what format/preconditions apply, so it fails to compensate for the coverage gap.

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 states a specific verb and resource ('Create/link ... location in the existing quipassist connection'), which is far more informative than the bare name, and it implicitly separates this write from sync_quipassist_locations or preview_quipassist_sync. It does not explicitly name those siblings, so the differentiation relies on inference from the verb.

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?

The phrase 'in the existing quipassist connection' implies a precondition (the connection must already exist), and 'Review all transmitted fields' is a caution rather than a usage rule. There is no explicit guidance on when to call this versus sync_quipassist_locations, preview_quipassist_sync, or create_target_location.

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