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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and closed-world, so safety is covered. The description adds genuine substance beyond that: it discloses that the response includes declared inputs/outputs, persistence effects ('what stays usable after a run'), required settings, external reach with justification, test locations, and every file touched. It omits any mention of error or not-found behavior.

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, front-loaded with the core action and followed by a concrete use case. The enumeration of returned sections is long but each item conveys distinct information, so little is wasted.

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 single-parameter read tool with an output schema and full annotation coverage, the description supplies ample context about what the call yields and when to use it. Only edge-case behavior (missing or private recipes) is unaddressed.

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% and the single parameter already documents its owner/repo/task format with an example, so the schema carries parameter meaning. The description adds nothing about the recipe identifier format, leaving it at the baseline for a fully documented 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?

The description states a specific verb and resource ('Get one recipe in full') and enumerates what the full record contains, so its purpose is clear. It does not explicitly contrast itself with read_recipe_file or search_recipes, so an agent must infer that this returns structured recipe metadata rather than file contents.

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?

It gives one clear usage context ('Use it to tell the user exactly what a recipe will do before they run it'), which implies a pre-execution inspection workflow. However, it never states when not to use it or points to siblings like search_recipes for discovery or read_recipe_file for file contents.

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