What can I make

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

With no annotations, the description carries the full behavioral burden. It never says whether this is a read-only lookup, whether results are ranked, how ties or empty inventories are handled, or what the response contains. The near-miss explanation is useful but is essentially parameter semantics, not behavioral disclosure.

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 sentences, zero filler, and the core capability is front-loaded before the modifier parameter tip. 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?

For a simple read-style lookup with no output schema, the description covers the main flow but leaves the limit parameter and result shape entirely unexplained, and with no annotations those gaps are unaddressed elsewhere.

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 67%: ingredients and allowMissing are documented in the schema, and the description usefully extends allowMissing ('see what is missing'). However, the 'limit' parameter is undocumented in both schema and description, and default/format expectations for ingredients are not clarified.

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?

States a specific verb and resource: find recipes the user can make from ingredients on hand. This implicitly separates it from search_recipes (query-driven lookup) and get_recipe (retrieval by id), but it never names or contrasts those siblings explicitly.

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 second sentence gives a genuine usage cue for the near-miss mode ('Set allowMissing above 0 to include near-misses'), but there is no guidance on when to prefer this over search_recipes or get_recipe, and no prerequisites stated.

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