The three tools have clearly distinct purposes: health likely checks server status, now retrieves the current datetime, and parse converts datetime strings. There is no overlap or ambiguity between these functions.

All tool names follow a consistent pattern with a common prefix 'datetime.' and clear, concise suffixes (health, now, parse). This uniformity makes the set predictable and easy to understand.

Three tools is a borderline count for a datetime server; it covers basic operations but feels thin, potentially lacking advanced features like formatting, timezone handling, or date arithmetic that might be expected in this domain.

The tool set is significantly incomplete for datetime operations; it includes core functions (now, parse) but lacks essential tools for formatting, timezone conversion, date arithmetic, or validation, which are common in datetime libraries and could cause agent failures.
