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

The description adds real behavioral context the annotations do not: empty results are common per channel, and the call is chained after get_integration_schema. However, it says nothing about side effects, even though the annotations declare destructiveHint=true and readOnlyHint=false for what the description frames purely as a lookup — an obvious tension an agent would want explained. Not a flat contradiction, since the text never claims read-only, but a meaningful unexplained gap.

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 short sentences, front-loaded with what the tool returns and immediately followed by the prerequisite. The final "methodName is required" is mildly redundant with the schema's required array but is cheap and placed where it matters.

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?

With an output schema present, return values need no explanation, and the chaining prerequisite plus empty-result caveat cover the main usage risks. The only omission is any comment on the destructive/open-world side of the call, which the annotations claim but the text never acknowledges.

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?

It clarifies methodName's provenance (the methodName values returned by get_integration_schema in the tools array) and reiterates that it is required, which adds routing value beyond the field label. dataSchema and integrationId are left to the schema, but coverage is 67% so the schema carries most of the burden already.

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 specific verb ("look up") and resource ("channel-specific options") and concretizes it with examples — subreddit, Pinterest board, Discord/Slack channel — which immediately bounds the domain. It also differentiates itself from the sibling get_integration_schema by naming it as the prerequisite rather than an alternative.

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?

Explicitly gives the ordering rule ("Call get_integration_schema first to find the available methodName values") and an explicit when-not condition ("if it returns none, this tool has nothing to look up"), reinforced by "Many channels have none." An agent knows both when to call it and when to skip it.

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