generate_daily_insight

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

Without annotations, the description only partially discloses behavior: it lists gathered data and that a placeholder is stored, but omits whether the operation is idempotent, overwrites existing data, or has side effects like permissions or rate limits.

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 extremely concise with two clear sentences. It front-loads the purpose and efficiently lists the data sources using bullet-style line breaks, adding no filler.

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?

While the description covers the gather-and-store action, it lacks details on the nature of the placeholder (e.g., new vs. update) and ideal timing for invocation. For a simple tool with no params, it is adequate but not fully complete.

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?

No parameters exist, so the description does not need to add parameter info. The baseline for zero parameters is 4, and the description is sufficient.

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 assembles recent context for daily insight generation, listing specific data sources. It is distinct from siblings like 'get_daily_insight' but does not explicitly differentiate from other context-gathering tools.

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 on when to use this tool versus alternatives. It does not mention prerequisites, frequency, or relationships with siblings like 'daily_note' or 'get_daily_insight'.

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