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

With no annotations, the description carries the full burden and does so richly: it discloses that nothing is created until email confirmation, that no payment or wallet signature is required, the one-pass-per-Mind cap, and the exact idempotent behavior of repeat calls. It also names the returned fields (pending_verification, leaderboard, install link, invite link) that annotations cannot convey.

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 purpose and the key constraint (nothing is created until confirmation) are front-loaded, and the sentences are information-dense rather than padded. It runs long at roughly five sentences, with some overlap between the return-value and repeat-call details, but almost every clause earns its place.

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?

There is no output schema, so the description must explain returns, and it does: pending_verification, the public leaderboard, and, after confirmation, the Pass install link and personal invite link. Combined with the safety, idempotency, and confirmation-flow disclosures, an agent has everything needed to invoke it correctly.

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 100%, so the schema already documents all four parameters, establishing a baseline of 3. The description adds only marginal meaning, reinforcing that mind_id must be the caller's real id because the one-per-Mind cap keys on it, and alluding to the per-event scoping that maps to event_slug.

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 (Claim) and a precisely named resource (the free VIA x Singapore Blockchain Week Network Pass for the calling Mind's owner), so the agent knows exactly what gets created. It does not, however, differentiate itself from the sibling claim_pass, leaving the agent to infer which claim tool applies when.

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?

Usage is implied by the description of outcomes rather than stated as a when-to-use rule; there is no explicit condition or named alternative (e.g. claim_pass or get_via_overview) for the agent to compare against. The one-pass-per-Mind cap and idempotent repeat behavior do give useful invocation context.

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