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

Annotations already cover the safety profile (read-only, idempotent, non-destructive, closed-world), so the description's real contribution is provenance and output behavior: turkey times sourced from USDA FSIS and dish times from each recipe, plus the fact that it detects dishes that don't fit the ovens and supplies fixes. That is meaningful context beyond the annotations, though it says nothing about output format or size.

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?

It is a single long sentence with the core purpose front-loaded and each clause adding a distinct output element, so nothing is wasted. The run-on structure makes it slightly harder to scan than a short bulleted breakdown would be.

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?

With no output schema, the description needs to tell the agent what comes back, and it does: a dated prep schedule, turkey timing, oven assignments, and conflict fixes. Combined with a fully documented optional-only schema and read-only annotations, the definition is nearly complete, missing only a note on result size or format.

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 every parameter is documented with defaults and enum meanings, so the schema carries the burden. The description adds almost nothing parameter-specific beyond 'Every setting is optional', 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 names a specific artifact (a Thanksgiving cooking schedule worked back from dinner time) and enumerates what it contains: day-by-day prep, turkey in/out times, per-oven dish assignment, and overflow dishes with fixes. That level of detail separates it cleanly from siblings like turkey_calculator, which handle only a slice of the same problem.

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?

Usage is implied by the scenario (planning a Thanksgiving cook) and 'Every setting is optional' signals it can be called with defaults, but there is no explicit when-to-use vs. when-to-pick-turkey_calculator guidance and no stated exclusions. An agent must infer the boundary from the purpose statement alone.

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