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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered externally. The description adds genuine behavioral value by disclosing what comes back for each button (id, words, URL key, trigger word, permissions, extra fields), which matters because there is no output schema. It says nothing about ordering, pagination, or behavior when the integration has no buttons.

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?

One compact sentence with no filler, and the resource is front-loaded before the field enumeration. The terseness costs a little clarity because the sentence has no predicate, but nothing is wasted.

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 one-parameter read-only list tool whose annotations carry the safety profile, the description is largely sufficient, and it fills the gap left by the absence of an output schema by enumerating return fields. Minor omissions (ordering, empty result, no-link to press_button/update_button workflow) keep it below 5.

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?

There is a single required parameter with 100% schema description coverage, including the helpful note that the uuid comes from list_integrations. The description only alludes to the integration implicitly ('An integration's buttons') and adds no format or sourcing detail beyond the 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 names the resource (an integration's buttons) and enumerates the fields each button carries, but it is a noun-phrase fragment with no verb, so it never actually states that it returns a list. Siblings like create_button, update_button, remove_button and press_button are not mentioned, leaving the agent to infer the read-only scope from the name alone.

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 guidance on when to call this rather than siblings such as get_integration_sample_shape, press_button or update_button, and no statement of prerequisites beyond the schema. The only hint is the field mention 'from list_integrations' inside the schema, not the description.

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