append_daily

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

With no annotations, the description carries the burden of behavioral disclosure. It adds 'timestamped' and 'today's journal Log', but omits details like whether the log is auto-created, idempotency, or permission needs. Given the tool's simplicity, this is adequate but not comprehensive.

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, front-loaded sentence with no wasted words. It clearly communicates the action, target, and content scope in a compact form.

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 one-parameter append tool with an output schema available, the description covers core behavior and usage context adequately. It doesn't address edge cases like missing log creation, but it's sufficient for typical use.

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 only provides a type 'string' for 'text', while the description gives the parameter semantic meaning by listing suitable content (decisions, conclusions, etc.) and implying automatic timestamping. This compensates well for the 0% schema coverage.

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 uses a specific verb 'Append' plus a clear resource 'today's journal Log', and specifies content types (decisions, conclusions, etc.). This distinguishes it from sibling tools like create_note or edit_note which target general notes rather than a daily log.

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?

It conveys when to use the tool ('as they happen' for decisions/conclusions/work) which is clear context. However, it does not explicitly state when not to use it or mention alternatives, so it falls short of a full 5.

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