sleep_and_plan

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

With no annotations, the description must fully disclose behavioral traits, but it only mentions that it 'runs' the sleep cycle and lists return values. It does not clarify whether the tool mutates memory, has prerequisites, or any side effects, leaving the agent uncertain about the operation's safety and impact.

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 description is a single sentence that clearly states the action and expected outputs without any unnecessary words. It is well-structured and front-loaded with the primary verb and resource.

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?

The description lists the main outputs but omits crucial context: the meaning of the 'days' parameter, any side effects of running the sleep cycle, and usage guidance relative to sibling tools. Given the combined nature of the operation, this lack of detail is inadequate for reliable invocation.

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?

The input schema has one parameter 'days' with no description, and the tool description does not explain what it does. Schema coverage is 0%, and the description provides no semantic context for the parameter, leaving it completely ambiguous.

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 clearly states the tool runs the full sleep cycle and returns specific outputs (consolidation summary, weak-important replay count, refreshed practice plan/forecast). This distinguishes it from single-purpose siblings like 'sleep' or 'practice_plan' by combining both actions.

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 description implies usage for running sleep and getting a refreshed plan/forecast, but it does not explicitly state when to choose this over alternative tools or when not to use it. No exclusions or alternatives are mentioned.

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