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

Annotations already declare readOnly/idempotent/non-destructive/closed-world, so the description does not need to restate safety. Instead it adds genuinely new behavioral context about the response: the schema may demand an id, that ids come from 'tools', and that 'tools' may contain a mention lookup. That is workflow information an agent cannot get from 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 first two sentences restate the same idea ('we need to understand the schema' / 'helps us get the schema'), and the third sentence has a typo ('the requires some id') that slightly obscures meaning. The follow-up guidance is useful, but the prose could be halved without losing information.

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 2-parameter read tool with an output schema, the description supplies the missing piece: what to do with the result (resolve ids via 'tools', then triggerTool) and the mention-lookup path. An agent can call this correctly and knows the next step, though a note on premium gating (isPremium) is absent.

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 100% and the platform enum is fully enumerated in the schema, so the structured data already carries the parameter burden. The description mentions neither 'platform' nor 'isPremium' and adds no semantics beyond the schema; 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?

States a specific resource and action ('get the schema of the integration') and frames it in the workflow of scheduling a social media post, which distinguishes it from siblings like integrationSchedulePostTool or integrationList. The first-person phrasing ('we need to understand') is less direct than a crisp verb+resource statement, but the intent is unambiguous.

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?

Gives an explicit trigger ('Everytime we want to schedule a social media post') and a follow-up rule: if the returned schema requires an id, look in 'tools' and call triggerTool. It also flags the mention-lookup use case for tagging people/pages. What it lacks is any statement of when NOT to use it or how it differs from integrationList.

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