homey_run_flow_card_action

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

No annotations are provided, so the description carries the full burden. 'Manually execute' implies a mutation, but there is no disclosure of side effects, whether the execution is immediate or persistent, or any required permissions. This is a significant gap for a tool that triggers actions.

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 description is a single, front-loaded sentence that immediately states the action and target. It is concise and easy to scan, though it could arguably be more informative without losing conciseness.

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 tool with a nested object parameter (args), no output schema, and many similarly named siblings, the description is too thin. It doesn't explain what 'execute' entails, what the return value looks like, or how it relates to running entire flows, leaving the agent without sufficient context to invoke it appropriately.

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 100%, with each parameter (uri, id, args) having its own description. The tool description adds no extra meaning beyond the schema, but since the schema already explains parameters well, a baseline 3 is appropriate.

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 'Manually execute a specific flow card action' clearly states the verb (execute) and resource (flow card action), and the word 'specific' hints at focusing on one card action rather than a whole flow. However, it doesn't explicitly differentiate from sibling tools like homey_run_flow or homey_get_flow_cards, so it's clear but not fully distinguishing.

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 description offers no guidance on when to use this tool versus alternatives. With many related sibling tools (run_flow, run_advanced_flow, get_flow_cards), there is no stated context or exclusions, leaving the agent to infer usage from the name alone.

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