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

Annotations include readOnlyHint: false, indicating it's not read-only, but the description doesn't add behavioral context beyond this. It doesn't disclose if it's a pure generation tool (likely non-destructive), any authentication needs, rate limits, or output format. With annotations covering basic safety, the description adds minimal value, scoring baseline for adequate but limited transparency.

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 a single phrase, 'Generate crontab expressions', which is front-loaded and wastes no words. It efficiently conveys the core function without unnecessary elaboration, making it highly readable and to-the-point.

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 tool has 5 parameters, no output schema, and annotations only cover readOnlyHint, the description is incomplete. It doesn't explain what the tool returns (e.g., a crontab string, validation result), how parameters combine, or error handling. For a generation tool with multiple inputs, more context is needed to guide effective 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?

Schema description coverage is 100%, with each parameter (minute, hour, dayOfMonth, month, dayOfWeek) well-documented in the schema. The description adds no additional meaning beyond the schema, such as explaining parameter interactions or default behaviors. Baseline score of 3 is appropriate since the schema handles the heavy lifting.

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 'Generate crontab expressions' states the basic purpose but is vague. It specifies the verb 'generate' and resource 'crontab expressions', but doesn't clarify what type of generation (e.g., from parameters, validation, examples) or distinguish it from potential siblings like scheduling tools. It's functional but lacks specificity.

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 provides no guidance on when to use this tool versus alternatives. There are no explicit when/when-not instructions, no mention of prerequisites (e.g., needing specific time values), and no reference to sibling tools (e.g., other scheduling or conversion tools in the list). Usage is implied but not articulated.

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