recipe_timeline_create_one

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

With no annotations provided, the description carries the full behavioral burden, yet it only reveals the endpoint and method. It does not mention authentication requirements, permission scope, whether the event is attached to the caller's user, or idempotency/duplicate handling for a mutation that creates persistent state.

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 first three statements are tight and front-loaded, but the long comma-separated keyword dump roughly doubles the length without adding meaning, which is the opposite of earning each sentence.

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 mutation tool with no annotations, no output schema, and an entirely undocumented nested body, the description should explain required inputs and the effect of creation. It supplies only the endpoint path, so an agent cannot confidently populate the body or predict the result.

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% and the single 'body' parameter is a nested object requiring recipeId, subject, and eventType plus optional timestamp, image, userId, and eventMessage. The description explains none of these fields, their formats, or the enum constraints on eventType/image, leaving the agent with zero semantic help.

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+resource ('Create event' on the 'Recipe: Timeline' resource) and the HTTP endpoint confirms the write intent, so it is distinguishable from siblings like recipe_timeline_get_one/update_one/delete_one. However, it never explicitly names those siblings or states the scope is per-recipe, so differentiation is only implicit.

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?

There is no when-to-use guidance: nothing says an existing recipe is required first, that eventType must be one of the allowed values, or how this differs from update_event_image or recipe_timeline_update_one. The trailing keyword list ('add event, new event, make event') is search noise, not usage guidance.

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