Route everyday, well-defined work (single-file edits, test-writing, summarization, mechanical refactors, boilerplate) to a cheaper coding agent (Grok or Copilot CLI) instead of doing it in the main Claude session, escalating multi-file/architecture/debugging/security work to Claude. Opt-in via the `cheap_lane:` comfort-posture knob.
Authors, validates and packages a claude.ai Organization Skill — the intake questions, the trigger and scope exercises, then lint, pack and verify against measured platform constraints. Reach for this when someone wants to publish a Skill to their organization, or when an upload was rejected and the reason is unclear.

Dues pay for the room. The margin lives in ancillary: personal training, small-group/semi-private, retail, and café. The metric is revenue (and contribution margin) per member, and it rides on retention — you can't sell PT to a member who already quit.
| Line | Margin character | Attach lever |
|---|---|---|
| Personal training / semi-private | High-margin labor; premium to dues | Assessment at onboarding; goal-driven upsell |
| Retail (apparel, supplements, gear) | Merchandise margin; inventory risk | POS attach, curated assortment |
| Café / juice bar / smoothies | Food-service margin + traffic | Pre/post-class impulse; throughput |
| Workshops / challenges / events | Programmed high-margin bursts | Community + referral engine |
ancillary revenue per member = total ancillary revenue / active members
ancillary attach rate = members who buy ancillary / active members
Model these before touching dues pricing — a modest lift in PT attach often beats a risky dues increase. Attach and margin norms are [verify-at-use].
Ancillary rides on retention and onboarding:
weak retention? -> fix retention first (churned members buy nothing)
strong retention, low PT attach? -> build the onboarding assessment -> PT path
strong PT, no retail/café? -> add the highest-margin, lowest-ops line that fits your space
