get_chain

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

No annotations provided; description only details output fields (transition_type with ethics note, is_violent) but omits read-only nature, error behavior, or side effects.

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?

Two concise sentences: one describing output, one giving usage. Front-loaded with purpose; no wasted words, though could potentially be trimmed slightly.

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 output structure and usage hint but lacks error handling, pagination info, or response format for large chains. Adequate but with noticeable gaps.

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?

Single parameter chain_id with basic schema (integer, minimum 1) but 0% schema description coverage; description adds no input meaning or context beyond schema.

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?

Description clearly states it returns details of a succession chain with chronological links, specifying fields. 'Usa dopo search_chains' differentiates from sibling search tool.

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?

Explicitly directs to use after search_chains, providing clear context and ordering among siblings. However, no mention of when not to use or alternatives.

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