find_recipes_for_item

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

No annotations are provided, so the description carries the full burden. It implies a read operation and discloses that item and recipe ids are different id spaces. However, it does not explicitly state read-only behavior or mention any side effects, which would make it a 5.

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 three sentences long, each serving a purpose: purpose, workflow, and edge case. No redundant words.

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 context of siblings (search_items, get_recipe, my_unlocks) and an output schema that likely documents return values, the description completes the picture by setting up the workflow and explaining empty results.

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 0%, so the description must compensate. The description does not add any meaning to the parameter 'item_id' beyond the schema (integer type). It mentions that item ids are from a different namespace, but does not describe the parameter itself.

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 clearly states the verb 'Find' and the resource 'crafting recipe ids that PRODUCE the given item id'. It distinguishes itself from siblings like 'get_recipe' and 'search_items' by specifying the direction (production) and the follow-up actions.

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 explicitly says when to use the tool ('after search_items'), what to do next ('follow up with get_recipe... and my_unlocks'), and explains the meaning of an empty result ('not craftable'). This provides excellent workflow guidance.

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