Implementation Reference

  • The implementation of getMapEvents which retrieves the events array from a given map file.
    export async function getMapEvents(projectPath: string, mapId: number): Promise<(MapEvent | null)[]> {
      const map = await getMap(projectPath, mapId);
      return map.events;
    }
Behavior2/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. While 'Get' implies a read-only operation, the description fails to disclose whether this is idempotent, whether it returns deleted events, expected response size/performance implications for large maps, or the data format returned.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The single sentence is efficiently structured with no redundant words. However, given the lack of annotations and schema descriptions, the extreme brevity leaves critical gaps that additional sentences should fill.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the domain complexity implied by siblings (game development with actors, skills, states), the description inadequately explains what an 'event' represents in this context, what properties are returned, or how map events relate to the game systems. No output schema exists to compensate.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description partially compensates by referencing 'a specific map,' giving semantic context to the 'mapId' parameter. However, it fails to explicitly document that 'mapId' is the required identifier parameter or describe its expected format/value range.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Get') and resource ('all events from a specific map'), clearly indicating this retrieves multiple events. The use of 'all' helpfully distinguishes this from the sibling tool 'get_map_event' (singular), though it doesn't explicitly contrast with 'search_map_events'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 'get_map_event' (for single event retrieval) or 'search_map_events' (for filtered queries). No prerequisites or error conditions are mentioned.

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