claims_card_chain

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

No annotations provided, so description must cover behavior. It explains validation conditions but does not disclose side effects, persistence, or permissions. Adequate for a non-destructive linking operation.

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?

Three sentences, front-loaded with purpose, no superfluous words. Every sentence 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?

Describes workflow and validation but does not mention return value or whether the card is mutated in-place or returned. Given no output schema, more detail on output would be helpful.

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%, but description adds value by specifying validation criteria for prev_card_hash (64-char hex) and prev_chain_index (non-negative integer), which are not in schema descriptions.

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?

Clearly states the tool links a new card to its predecessor by setting chain_index and prev_card_hash, with validation. Explicitly tells to call claims_card_sign next, differentiating from sibling tools like claims_card_sign.

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 a clear next step ('Call claims_card_sign next') and describes validations, but lacks explicit when-not-to-use or alternative tools. However, the context of chaining cards is clear.

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