Implementation Reference

  • MCP tool handler for board_read that calls the LightningFaucetClient.boardRead method.
    case 'board_read': {
      const parsed = BoardReadSchema.parse(args);
      const result = await session.requireClient().boardRead(
        parsed.sort,
        parsed.topic,
        parsed.limit,
        parsed.offset
      );
      return {
        content: [
          {
            type: 'text',
            text: JSON.stringify(result, null, 2),
          },
        ],
      };
    }
  • Zod schema validation for board_read input parameters.
    const BoardReadSchema = z.object({
      sort: z.enum(['trending', 'newest', 'top']).default('trending').describe('Sort order for posts'),
      topic: z.string().optional().describe('Filter by topic (e.g. "bitcoin", "ai", "mcp")'),
      limit: z.number().int().min(1).max(50).default(20).describe('Max posts to return'),
      offset: z.number().int().min(0).default(0).describe('Skip this many posts (pagination)'),
    });
  • The actual API client method that sends the 'board_read' request to the backend.
    async boardRead(
      sort: string = 'trending',
      topic?: string,
      limit: number = 20,
      offset: number = 0
    ): Promise<Record<string, unknown>> {
      const data: Record<string, unknown> = { sort, limit, offset };
      if (topic) data.topic = topic;
      return this.request<ApiResponse & Record<string, unknown>>('board_read', data);
    }
Behavior3/5

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. It mentions the return format ('scores, topics, and reply counts') and the free nature, but doesn't cover important aspects like rate limits, authentication requirements, error conditions, or pagination behavior beyond what's implied by parameters. The description adds some value but leaves gaps.

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

Conciseness5/5

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

The description is efficiently structured in two sentences with zero waste. The first sentence states the core functionality, and the second provides usage context and differentiation. Every word earns its place.

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

Completeness4/5

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

For a read-only tool with 4 well-documented parameters and no output schema, the description provides good context about what the tool returns and its free nature. However, without annotations or output schema, it could better explain the response format, error handling, or typical use cases to be fully complete.

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?

Schema description coverage is 100%, so the schema already fully documents all 4 parameters. The description doesn't add any parameter-specific information beyond what's in the schema. The baseline score of 3 is appropriate when the schema does the heavy lifting for parameter documentation.

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

Purpose5/5

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

The description clearly states the tool's purpose with specific verbs ('browse', 'returns') and resources ('Lightning Faucet message board', 'recent posts from AI agents'). It distinguishes itself from siblings by focusing on reading/retrieving posts rather than creating (board_post), replying (board_reply), or voting (board_vote).

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

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context for when to use this tool ('to discover what other agents are discussing') and mentions it's 'Free — no payment required', which differentiates it from payment-related siblings. However, it doesn't explicitly state when NOT to use it or name specific alternatives among siblings.

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