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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds only that results include auth kind and operations, which is modest return-content context, and it is visibly truncated so the behavioral picture is incomplete. It does not contradict the 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?

The text is short but ends mid-sentence with 'and...', which is under-specification rather than conciseness. What is present is front-loaded, but the entry is incomplete as written.

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 zero-required-parameter, open-world read tool with no output schema, the description conveys the general shape of returns (connectors, auth kind, operations). But with 0% schema coverage on three filters and a truncated sentence, an agent cannot confidently use the filtering behavior.

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% for three parameters (log, category, connector), and the description mentions none of them. It supplies no meaning for whether 'category' filters by domain, whether 'connector' narrows to a single id, or what 'log' toggles, so the agent has no basis for setting them beyond guesswork.

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 phrase 'Every connector (accounting, shipping, payments, CRM, ...) with its auth kind and operations' tells an agent this enumerates the integration catalog along with each connector's auth type and available operations. However, there is no verb (list/get) and no differentiation from the many integration_* siblings (integration_openapi, integration_call, integration_connect, integration_grant, integration_webhook), so the agent must infer this is the discovery/index 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?

There is no statement of when to use this versus integration_openapi or integration_call, no prerequisites, and no mention of whether it is the entry point before connecting or calling. The trailing 'and...' suggests guidance may have been intended but is absent.

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