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

The description discloses crucial behavior beyond annotations: there is no backend signing path and 'Crank NEVER co-signs a claim', the returned transaction must be signed by the caller, and the tool returns a no-op result when nothing is claimable. It also explains that claims are free of technology service fees. This is consistent with the idempotentHint=false, destructiveHint=true, and readOnlyHint, no contradiction.

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 description is well structured and dense: each block adds distinct value—the claim action, the unsigned-transaction behavior, the the nothing-to-claim branch, the fee policy, and the workflow. There is no redundant prose or vague filler.

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?

The description very thoroughly covers behavior, edge cases, fee, and workflow, and the output schema can carry the return details. It loses slightly on contextual completeness only because parameter roles are not explained for a multi-parameter mutation tool with 0% schema coverage.

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?

The input schema has 5 parameters with 0% schema description coverage, and the description does not explain the required parameters like launch_id and wallet_address, nor optional ones like idempotency_key or pledger_token_account. It only generically mentions 'your own wallet' and 'your own allocation', which is too thin to properly disambiguate the parameters.

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?

The description opens with a specific verb and resource: 'Claim the launch tokens your liquidity release schedule has unlocked.' It clearly distinguishes itself from status-check siblings by describing the action and the two action-response forms: sign_required and nothing_to_claim.

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 description provides an explicit workflow: 'poll get_my_pledge_status, claim when release.releasable_base_units is non-zero' and names the relevant sibling tool. It also clearly states the 'when not to claim' conditions by explaining when the tool returns nothing_to_claim instead of a transaction.

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