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

Annotations already declare readOnlyHint=false, openWorldHint=true, idempotentHint=false and destructiveHint=false, so the safety profile is partly covered. The description adds only that calls run with the caller's 'sealed credentials' – a genuinely useful auth detail – but says nothing about side effects, rate limits, error behavior for unknown ops, or the fact that behavior varies entirely by the chosen operation, which matters a lot for an open-world dispatcher.

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 description is a single sentence that terminates mid-clause ('or with...'), so it is under-specified rather than concise. The most important information (what a call does, what args carries, how credentials are selected) is missing or cut off.

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 an open-world, non-idempotent, arbitrary-operation dispatcher with 4 parameters, one of them a free-form nested args object, no output schema and no enum constraints, the description should explain op/args semantics and expected results. It does neither, and the dangling clause signals it was truncated before completing its point.

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%, so the description must carry the load. It partially covers 'connector' (discoverable via integration_list) and 'op' (one operation), but never explains the 'args' object – the key nested parameter that determines what actually happens – nor 'owner'. With nested objects and zero schema docs, this is a major 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?

States a verb ('Run') and a resource ('one operation') scoped to a connector, and points to integration_list as the way to discover operations. But the sentence is truncated ('or with...') and never says what an integration operation actually is, so the agent cannot distinguish this from siblings like integration_connect, integration_grant, or integration_webhook with confidence.

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 only routing signal is the parenthetical telling the agent to use integration_list to find connectors; there is no statement of when to use this versus integration_connect/integration_grant/integration_webhook. The trailing 'or with...' clause appears to have been meant as an alternative usage mode but is cut off, leaving the guidance incomplete.

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