trmnl_start_plugin_settings_connection

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

Annotations already declare readOnlyHint=false, openWorldHint=true, idempotentHint=false, so the description's 'Changes remote state or starts work' mostly restates them. It does add the meaningful noun 'provider authorization', implying an external third-party OAuth flow, but omits that the call returns a pending attempt requiring a subsequent confirm/cancel step.

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?

Front-loaded with the action and kept to three short sentences with no filler. The raw HTTP path is somewhat verbose but serves as an unambiguous operation identifier.

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?

Given nested required objects, 33% schema coverage, no output schema, and a non-idempotent remote mutation, the description is thin. It never explains the authorization lifecycle (attempt → poll → confirm/cancel) an agent needs to drive this flow correctly.

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% — just 'profile' is documented — and the description explains none of action_id, revision, callback_id, or the path identifiers. For a nested-body mutation tool with low coverage, the description needed to compensate and does not.

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 ('Start provider authorization') and pins the exact endpoint, so the agent knows this initiates a connection attempt. It does not, however, distinguish itself from the closely named sibling trmnl_start_plugin_installations_connection, leaving the plugin-settings vs installations choice ambiguous.

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?

'Run only within the user-authorized scope' is a permission caveat, not usage guidance. Nothing says when to call this versus the installations variant, nor that the resulting attempt must be completed via trmnl_get_connection_attempt / trmnl_confirm_connection_attempt / trmnl_cancel_connection_attempt.

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