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

No annotations provided, so description carries full burden. It discloses the internal two-step process (calls whoami, then conditionally bootstrap), explains the conditional binding logic ('if not yet bound'), and lists return fields (user_id, api_key_id, etc.) despite no output schema existing. Could mention error states or retry behavior.

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?

Four sentences with zero waste: (1) purpose, (2) implementation mechanism, (3) usage timing, (4) return values. Well-structured and front-loaded. No redundant phrases or tautology.

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 zero-parameter setup tool with no annotations, the description is comprehensive. It compensates for the missing output schema by explicitly documenting return values. Covers prerequisites (MCP server started), internal behavior, and success indicators (client_id_bound status).

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?

Tool has zero input parameters. Per evaluation rules, zero parameters establishes a baseline of 4. The description correctly focuses on behavior and return values rather than inventing parameter documentation.

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?

Specific verbs ('Check', 'ensure', 'bind') clearly state the tool verifies connection status and identity binding. It distinguishes itself from siblings by explicitly stating it 'Calls whoami' and 'bootstrap', positioning itself as a composite setup utility rather than requiring manual invocation of those lower-level tools.

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?

Provides explicit temporal guidance: 'Use this after starting the MCP server to confirm everything is ready for payment operations.' Clearly indicates this is an initialization/verification step. Lacks explicit 'when not to use' guidance (e.g., skipping if already verified), though it implies idempotency via 'if not yet bound'.

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