# Weekly Coaching Patterns Routine skill: reads the last 4 `compiled/activity-*.md` artifacts for steady sessions and detects whether cardiac drift is trending upward over time. Returns a fixed findings block for `reflect --check-id weekly-coaching-patterns --check claude-code-fitness-hermit:weekly-coaching-patterns` to classify and route. **Contract:** idempotent, read-only, no self-scheduling, short-running. Returns findings or silence — never creates proposals itself. ## Steps 1. **Run the trend check.** Issue a single Bash call: ``` bun ${CLAUDE_PLUGIN_ROOT}/scripts/fitness-lab.ts weekly-patterns ``` The script does the whole deterministic pass — filesystem only, no Strava token: globs `.claude-code-hermit/compiled/activity-*.md`, keeps entries whose frontmatter has `type: activity-note` AND `session_kind: steady`, takes the 4 most recent by `created`, reads each note's **signed** drift from the `cardiac_drift_bpm` frontmatter field, falling back to the body's `Cardiac drift:` line for notes written before that field existed (neither present → excluded; a negative value compares as smaller than any positive — the sign is never stripped), and evaluates a strict oldest-to-newest monotonic rise across all 3 adjacent pairs. It emits: ```json {"steady_sessions_found": <int>, "series": [{"file": "…", "date": "…", "drift": <signed int>}], "trend": "upward" | "none" | "insufficient-data"} ``` `series` is ordered oldest-to-newest. `trend: "upward"` ...
