services_fire_event

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

With no annotations, the description bears full responsibility for behavioral disclosure. It only states 'Fire' implying a write operation, but fails to detail side effects, permissions, or response behavior. Minimal transparency.

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 extremely concise at 5 words, but it lacks structure such as categorization, prerequisites, or examples. While brevity is valued, it sacrifices necessary detail.

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 the tool has two parameters and an output schema, the description is incomplete. It omits important context like valid event types, whether event_data is free-form, and the nature of the return value. The existing output schema reduces the need to explain returns, but parameter documentation is still missing.

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% and the description adds no semantic meaning to the parameters. It does not clarify acceptable values for event_type or the structure of event_data, leaving the agent with no guidance beyond the bare schema.

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 'Fire a Home Assistant event' clearly states the action verb and resource, indicating it triggers an event in Home Assistant. It distinguishes from sibling tools that perform specific actions like turning on entities or calling services, as this is a generic event firing tool.

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?

No guidance is provided on when to use this tool versus alternatives like services_call_service or ws_listen_events. The description lacks any context about appropriate scenarios or exclusions.

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