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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds genuinely useful behavioral context beyond that: results are organized under a 'tools' key, helpers must be executed via triggerTool, and mention lookups may be included. It doesn't discuss caching or rate limits, but that is minor.

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 is returned and followed by the actionable triggerTool guidance. There is mild redundancy between the 'for example' parenthetical and the later id examples, but nothing wasted overall.

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, the description needn't enumerate return fields, and it still usefully sketches the 'tools' structure and the follow-up call pattern. For a 2-parameter read-only tool with full schema coverage and annotations, this is essentially complete.

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%: the platform enum values and the isPremium boolean are fully documented in the schema. The description adds no parameter-level meaning (e.g., how premium status alters the returned schema), so the baseline 3 applies.

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 resource and outcome: it returns the post settings a channel's network requires before a post can be scheduled, with concrete examples (board, subreddit, title). This is far clearer than the opaque tool name 'integrationSchema'. It doesn't explicitly separate itself from the similarly named sibling postSettingsTool, so it stops short of a 5.

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?

It gives a clear usage context (before scheduling a post to a network) and explicitly routes the agent to the sibling triggerTool when a setting needs an id from the network. It does not clarify when to use postSettingsTool or integrationList instead, so alternatives are only partially covered.

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