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

Annotations already cover the safety profile (readOnlyHint=false, destructiveHint=false, openWorldHint=true). The description adds two genuinely useful behavioral facts: the output is a link, and secrets must never be transmitted. It does not say what the link looks like, whether it expires, or that idempotency is required, so the addition is partial.

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?

Two short sentences, front-loaded with the action, with no filler. It is efficient, though the terseness is partly under-specification rather than disciplined compression.

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 5-param tool with a nested object, no output schema, and no schema descriptions, the description is thin. Delegating flows/fields to guides_get is a reasonable mitigation, but it makes correctness depend on an external call and leaves idempotency_key and provider semantics unexplained.

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% across 5 parameters, including a nested `setup` object with `flow`, `environment`, and `credential_fields`. The phrase 'flows and fields' gestures at setup.flow and credential_fields but explains neither, and workspace, provider, purpose, and idempotency_key are completely unaddressed, so the description does not compensate for the coverage gap.

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 and resource: 'Create a browser connection link', which maps to connecting a service via a link-based flow. It is distinguishable from connections_list/connections_update, though the term 'browser connection link' is somewhat jargon-y and the description never names the provider/workspace scope that the required params imply.

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 prerequisite pointer ('Read guides_get doctrine/trust connections-and-activity for flows and fields') and a hard constraint ('never send secrets'), which is real usage guidance. But it never says when to use this versus connections_action_run, connections_update, or connections_list, so the agent must infer the routing.

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