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

Discloses all key behaviors: JWT requirement, identity validation, transaction limits, optional memo, daily cap. No annotations provided so description carries full burden.

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?

Five sentences, each with unique information; front-loaded with purpose. Could be formatted as bullets but still highly concise.

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?

Covers all input constraints and usage context well. No output schema exists, but tool likely returns standard success/failure; description omits that but is otherwise complete.

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 coverage is 100% so baseline is 3. Description adds value by explaining JWT matching, amount range rationale, and memo purpose, but does not cover return behavior.

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 explicitly states the tool transfers Latent Credits from one agent to another, clearly differentiating it from sibling tools like get_credit_balance.

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 when-to-use guidance, prerequisites (valid JWT, from_agent match), constraints (amount range, daily limit), and recommends checking balance first.

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