# sifu

> A personal tai chi instructor agent that teaches the Yang-style 24-Form one move at a time over text — pacing, daily accountability, eyes-free correction, and a code-enforced stop-and-see-a-physician safety boundary. "A sifu in your pocket."

## What it does
- Teaches the Yang-style 24-Form one move at a time, gating the next move on the last — you never overload.
- Holds you accountable daily over iMessage: a nudge, streaks, plateau detection; celebrates consistency over duration (10–15 min most days).
- Corrects your form without a camera: asks one feeling-first question whose answer reveals the fault, then gives the single matching cue, coaching the internal principles (relaxation/song, rooting, central equilibrium) — not just the shapes.
- Enforces a hard medical-defer boundary IN CODE: any real pain, dizziness, or chest tightness stops the session and refers you to a physician. It coaches movement; it never practices medicine.

## Who it's for
A solo at-home learner who wants a daily tai chi practice but has bounced off self-directed learning (books, videos, apps) because nothing sequenced the material, held them accountable, or corrected them. Busy professionals seeking calm; older adults seeking balance and fall prevention; intimidated beginners. Benefits (balance, lower blood pressure, less stress, better sleep, calm) show at 4–6 weeks of consistency.

## Agent surface
sifu is itself an MCP server (Agent First). An operator agent can run the practice loop while the human just practices.
- MCP endpoint: https://sifu.guide/mcp (streamable HTTP, bearer-authenticated)
- Representative tools (verb-first): taichi_prep, overview, get_today_session, start_session, log_session, get_next_move, get_move_detail, get_principle, ask_coach, submit_self_assessment, record_how_it_felt, report_symptom, get_progress, get_streak
- Discovery: /.well-known/agents.json
- The medical-defer safety boundary is enforced in code on every tool that ingests user text — it cannot be disabled by any tool, level, or input.
