Coda Trigger Automation

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

With annotations only declaring readOnlyHint=false and openWorldHint=true, the description usefully adds that the payload schema depends on the automation's configuration and that the call returns a requestId for tracking — implying an asynchronous, side-effecting operation. It does not state permission requirements or what happens on a non-API-triggerable rule.

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 operation is front-loaded in the first sentence and the remaining sentences each add a distinct, non-redundant fact (payload optionality, event-type requirement, return value, rule_id discovery). Slightly longer than strictly necessary but no 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 write tool with an existing output schema and adequate annotations, the description covers the prerequisite, the payload caveat, and the tracking handle. The main remaining gap is the absence of cross-references to related tools for checking mutation status or for the adjacent push_button flow.

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 coverage is 100%, so the baseline is 3, but the description goes beyond it by explaining where rule_id comes from (the automation's settings in the Coda UI) and that the payload shape is dictated by the target automation rather than fixed.

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 ('Trigger a Coda automation rule') and clarifies it fires a named rule with an optional payload. It does not explicitly contrast itself with the nearest sibling, coda_push_button, which also fires automations, so it stops short of full sibling differentiation.

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 a real precondition ('The automation must have an API-triggerable event type'), which is useful context for when this tool will succeed. It offers no when-not guidance and never mentions alternatives such as push_button or how to poll the resulting requestId via coda_get_mutation_status.

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