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

With no annotations, the description carries the full behavioral burden and does well: it discloses execution order, output forwarding, the failure policy ('stops at the first failing step and reports which one failed'), and a concrete cost of 3 credits per call. It does not mention auth requirements or external side effects, so it falls short of full 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?

Four tight sentences, front-loaded with what the tool does and followed by failure behavior and cost. Every clause carries information; nothing is redundant padding.

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?

No output schema exists, and the description compensates by stating that every step's result is returned. For a 2-parameter mutation tool with nested inputs and no annotations, the main remaining gap is the undocumented input-contract detail, but the definition is otherwise sufficient to invoke the tool correctly.

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% for two parameters. The description adds one meaningful note — inputs are passed as an object — but says nothing about the 'name' parameter's format (the regex pattern lives only in the schema) and does not explain the shape or keys of the nested inputs object, so the compensation for the coverage gap is partial.

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 gives a specific verb and resource ('Run a saved recipe') and immediately clarifies the execution semantics — steps run in order, outputs pass forward. Against siblings like recipe_save, recipe_publish, recipe_list and recipe_delete, the agent can tell this is the executor without opening the schema.

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 word 'saved' implies the recipe must already exist (created via recipe_save), which is useful implied context, and it tells the caller to supply the recipe's inputs as an object. However, it names no alternative tool or explicit when/when-not condition, so guidance is inferred rather than stated.

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