swim-css
CSS = 200 / (T400 - T200) (m/s). The user provides their best 400m and 200m
times (in seconds or M:SS) — either as flags or via AskUserQuestion.
Run
python3 .claude/skills/swim-css/scripts/swim_css.py --t400 6:20 --t200 2:55
Present
CSS in m/s and pace per 100m, plus suggested training paces:
- CSS+5s/100m = endurance
- CSS = threshold
- CSS-3s/100m = VO2max intervals
Post-run: update snapshot
python3 .claude/skills/athlete-snapshot/scripts/update_snapshot.py --source swim-css --css-m-s <CSS>
Replace <CSS> with the computed CSS in m/s. Show alerts if any.
After presenting: persist to memory (MANDATORY)
Save a qualitative observation to memory — opinions, patterns, coaching notes. Never store raw numeric values (those are recomputable from the DB). Only write if the observation is NEW or CHANGED vs existing memory. See CLAUDE.md → Memory protocol.
