get_voluntary_fasting_dates

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

No annotations are provided, and the description does not disclose behavioral details such as error handling, date format outputs, or whether it supports all Gregorian months. The agent is left to assume basic behavior without safety cues.

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?

A single, well-structured sentence that communicates the core purpose and key details without unnecessary words. Information is front-loaded and easy to parse.

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 lack of output schema and annotations, the description is insufficient. It does not describe the return format (e.g., list of dates), error conditions, or coverage limitations. Agents may struggle to interpret the output correctly.

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 description provides context that the year and month are Gregorian, which is not explicit in the schema. With 0% schema description coverage, this adds value, but it does not explain valid ranges, constraints, or how parameters map to the output.

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 it returns recommended voluntary fasting days for a given Gregorian month, listing specific categories. The verb 'Return' and resource 'voluntary fasting days' are explicit, and it distinguishes from siblings like get_ramadan_dates or get_eid_dates.

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 on when to use or avoid this tool versus alternatives. The description implies usage for monthly fasting days, but lacks exclusions or comparisons to similar tools such as get_hijri_date or get_islamic_events.

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