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

Annotations declare readOnlyHint=false and destructiveHint=false, indicating a non-destructive mutation. The description adds the precondition 'after capability verification', which is meaningful context beyond annotations. However, it doesn't explain what the claim does (e.g., transfers tokens, marks as claimed), whether it's idempotent, or what authorization is needed. For a mutation tool, this is a significant gap.

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?

A single, front-loaded sentence that is concise and wastes no words. It efficiently conveys the core action and one precondition. It could arguably be slightly more informative, but it avoids verbosity.

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?

Given the tool is a non-destructive mutation with no output schema and annotations that only cover safety hints, the description is incomplete. It omits what happens on success (e.g., reward transferred, state updated), prerequisites (e.g., verification status), and error conditions. For a claim operation in a complex system with many siblings, this leaves too much unspecified.

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% – both poolId and operatorId are documented in the schema. The description adds no parameter details beyond what the schema provides. Baseline 3 is appropriate when the schema fully documents parameters and the description doesn't compensate with extra semantics.

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 states a specific verb+resource: 'claims an investment pool reward', which is clear and distinguishable from siblings like claim_bounty, claim_ip_revenue, and stake_in_pool. It doesn't explicitly name those alternatives, but the resource 'investment pool reward' is specific enough to disambiguate.

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?

No when-to-use or when-not-to-use guidance is provided. It mentions 'after capability verification' as a precondition but doesn't explain how the agent should verify this, or what alternatives exist (e.g., stake_in_pool, get_pool_earnings). An agent would have to infer usage from context alone.

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