append_tasks

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

With no annotations, the description carries full burden but only states 'Append tasks' – it does not disclose whether the file is created if missing, how existing content is handled, or what the return value is. Behavioral traits like side effects or error conditions are absent.

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 at two short sentences, with no wasted words. Every part is necessary and front-loaded: first sentence states action, second sentence specifies format. Ideal for quick comprehension.

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?

Given the simple operation (append tasks to a file) and the availability of an output schema, the description is minimally adequate. However, it omits details like file creation behavior and error handling, which could be important for agent decision-making. It covers the essential purpose but lacks completeness for a robust tool experience.

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 0% description coverage and defines items as an array of objects with 'additionalProperties: true', which is very permissive. The description provides critical structure by specifying 'Each item: {text, deadline?}' – this adds meaningful constraints beyond the schema and clarifies the intended format. However, the 'path' parameter is not explained beyond the schema default.

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 verb 'Append', the target resource 'tasks.md', and the format of each item ('{text, deadline?}'). It is specific and leaves no ambiguity about what the tool does. The sibling tools are unrelated, so no confusion arises.

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 explicit guidance is provided on when to use this tool versus alternatives. Sibling tools are for different purposes, but the description does not include any contextual cues or prerequisites, leaving the agent to infer usage from naming alone.

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