trmnl_confirm_connection_attempt

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

The annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=true, so 'Changes remote state or starts work' mostly restates them. The description does add a genuine authorization context ('user-authorized scope'), but says nothing about whether the confirmation is single-use, whether the attempt expires, or what happens to the attempt after success.

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 fragments with the action front-loaded, but the first sentence is a run-on that jams the verb phrase into the raw endpoint string, and 'Changes remote state or starts work' is boilerplate filler.

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 state-changing tool with nested objects, no output schema, and low schema coverage, the description covers the mutation and authorization scope but leaves the agent without any picture of the result or the lifecycle of the connection attempt. Adequate to invoke, thin on consequences.

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 only 33%, but the description does clarify that 'confirmation' is the value supplied by the provider callback, which is real semantic value beyond the bare string type. The path.id parameter and the profile parameter are left to the schema, and no format or sourcing detail is given for the confirmation value.

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 action (attaching a confirmation to a connection attempt) and anchors it to the concrete endpoint POST /api/plugin_connection_attempts/{id}/confirmation, so an agent can tell what resource is being mutated. It stops short of distinguishing this tool from siblings like trmnl_get_connection_attempt or trmnl_cancel_connection_attempt.

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?

The only usage constraint is 'Run only within the user-authorized scope,' which is a safety caveat rather than guidance on when to call this versus get/cancel connection attempt. Nothing states the precondition that a connection attempt must already exist or that the confirmation comes from an out-of-band provider callback flow.

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