send_weekly_digest_now

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

With no annotations, the description carries the burden. It discloses that the tool works standalone and immediately sends the digest, but does not discuss side effects (e.g., overriding scheduled sends, frequency limits) or what happens if the configuration is missing.

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 three sentences and two examples. It front-loads the primary action and includes relevant details without any wasteful words. Each sentence serves a clear purpose.

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 zero-parameter, trigger-only tool, the description is fairly complete. It explains the action, content, and standalone nature. However, it omits any mention of the return value or confirmation step, which would improve completeness.

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?

There are zero parameters, and schema coverage is 100%. The description adds value by clarifying that the recipient is pre-configured, which explains the lack of a recipient parameter. This meets the baseline expectation for a parameterless tool.

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 that the tool sends the weekly email digest immediately, mentioning its contents. However, it does not differentiate from sibling tools like 'send_digest_now' or 'send_report_now', which may overlap in functionality.

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 the tool is for triggering the weekly digest on demand, but lacks explicit guidance on when to use it versus alternatives or any prerequisites. Examples provide context but no exclusion criteria.

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