day_recap

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

No annotations are provided, so the description carries the full burden. It only states the output format (JSON) and content categories, but does not disclose behavior regarding the optional 'day' parameter, default behavior, or what the recap actually covers. This is insufficient for an agent to understand tool behavior beyond the basic output.

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 with no wasted words, clearly front-loaded with the core purpose. It lacks structural breakdown of the output fields, but that is not strictly required for conciseness. It earns a strong score for brevity.

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 tool is relatively simple with one optional parameter and an output schema, but the description lacks essential context: what 'day' expects, what happens if omitted, and how this differs from related tools. Given the output schema exists, not explaining return values is acceptable, but the usage context is missing.

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 schema has zero parameter descriptions (0% coverage), and the description does not explain the 'day' parameter's format, allowed values, or default behavior. With only one parameter and no compensation in the description, an agent has no idea what to pass.

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 indicates the tool produces a compiled day recap with specific categories (apps, away, meetings, agents) and notes the JSON output. It distinguishes from sibling tools that focus on current status or specific sessions, though it lacks an explicit verb like 'get' or 'retrieve'.

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?

No guidance is provided about when to use this tool instead of alternatives like active_now or what_was_i_doing. The description does not mention typical use cases, prerequisites, or exclusions.

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