Body \{input\} -\> \{ok, repaired, applied\}. Costs $0.001 USDC on Base per ca
- `yaml\_to\_json`: Converts a YAML subset \(block maps, sequences, nested indentation, scalars, comments\) into JSON with no runtime dependency. Body \{input\} -\> \{ok, value, warnings\}. Costs $0.001 USDC on Base per call.
- `cron\_next\_run`: Computes the next UTC fire time for a 5-field cron expression \(supports steps, ranges, lists, and month/weekday names\). Body \{expr, after?\} -\> \{ok, next, epochMs\}. Costs $0.001 USDC on Base per call.
- `text\_diff`: Produces a unified diff plus added/removed counts between two texts \(LCS line diff, configurable context lines\). Body \{old, new, context?\} -\> \{ok, identical, added, removed, hunks, unified\}. Costs $0.001 USDC on Base per call.
