feat: add 'prime' subcommand for LLM agent orientation#21
Merged
Conversation
Per quantcli shared contract §6, every CLI exposes 'prime' printing a one-screen primer aimed at LLM agents calling the CLI as a tool. Same section structure across all three repos (WHAT IT IS / OUTPUT FORMATS / AUTH / DATE FLAGS / SUBCOMMANDS / EXAMPLES / GOTCHAS) so an agent that has read crono's prime knows where to look in liftoff's. https://github.com/quantcli/common/blob/main/CONTRACT.md#6-the-prime-subcommand Liftoff-specific content covers: - workouts list/show/stats and bodyweights list/stats - Local-zone date semantics - LIFTOFF_API_BASE override for the periodic API host rotation - jq recipes for volume math and bodyweight delta Also extends the rootCmd Long description so 'liftoff-export --help' points agents at 'prime' from the top.

Three small gaps the new 'prime' subcommand surfaced when its examples
were exercised end-to-end:
- 'bodyweights list' had no --format flag at all, but the prime's
bodyweight-delta example pipes 'bodyweights list --since 90d --format
json' into jq. Add --format json (markdown stays default) emitting
[{"date":"YYYY-MM-DD","weight":N}, ...].
- 'workouts stats' printed plain-text "No workouts found." even when the
caller asked for --format json, breaking jq pipelines on empty
windows. Emit '[]' instead.
- printJSON encoded nil slices as 'null'. Match the prime's "JSON is
'[]'" promise by special-casing nil slices via reflect.
