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

With no annotations provided, the description carries the full burden, and it does convey that this is a single-record read ('Details of one ... event by id'), which is the key behavioral signal. It omits anything about missing/unknown ids, error behavior, or whether the lookup is scoped to a workspace — real gaps for a tool with zero annotation coverage.

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 first clause is well front-loaded and efficient. The trailing German restatement 'Details zu einem Event' is pure duplication that adds no information, diluting an otherwise tight one-liner.

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 single-parameter getter with no output schema, the description is minimally adequate: it tells the agent the lookup key and where to get it. Without annotations or an output schema, it should say more about the returned record or failure modes to be fully complete.

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?

One parameter (event_id) with 0% schema description coverage, so the description has to compensate — and it partly does by identifying the value's provenance ('from list_events'). It adds no format, type, or validity semantics beyond that origin hint.

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: retrieve the details of a single Golden Flame event by id. It also names the sibling that produces the id (list_events), which helps an agent distinguish it from list_events and get_tickets. It stops short of 5 because it never says what 'details' concretely includes.

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 parenthetical '(from list_events)' implies the workflow: get an id from list_events, then call this. There is no explicit when-not guidance or mention of what to do when the id is unknown/invalid, so usage is only implied rather than stated.

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