Configuration

Rate limits

devcoach has two rate-limit settings to prevent lesson overload:

Setting	Default	Range	Description
max_per_day	2	1–20	Maximum lessons in a rolling 24-hour window
min_gap_minutes	240	0–1440	Minimum minutes between consecutive lessons

Examples:

# Aggressive learning: up to 5 lessons/day, no minimum gap
devcoach set max_per_day 5
devcoach set min_gap_minutes 0

# Conservative: 1 lesson/day, must be at least 8 hours apart
devcoach set max_per_day 1
devcoach set min_gap_minutes 480

# Disable rate limiting entirely (not recommended)
devcoach set max_per_day 20
devcoach set min_gap_minutes 0

Via MCP tool:

{ "key": "max_per_day", "value": "3" }
{ "key": "min_gap_minutes", "value": "120" }

Via web UI: devcoach ui → Settings page.

Data location

~/.devcoach/coaching.db   — SQLite database

The database is created automatically on first run. All data is local — nothing is sent to any server.

Backup strategy

devcoach stores everything in a single SQLite file. Recommended backup approach:

# Daily cron / scheduled task
devcoach backup ~/Dropbox/devcoach-$(date +%Y%m%d).zip

# Before a major change
devcoach backup devcoach-before-reset.zip

The backup zip contains three files: - settings.json — rate-limit settings - knowledge.json — topics, confidence scores, and group assignments - lessons.json — full lesson history

All three are restored by devcoach restore <zip>.

---

Reset

To start fresh while keeping your lesson history:

# Save current knowledge before clearing
devcoach backup devcoach-before-reset.zip

# Re-run the onboarding flow
devcoach setup

To reset everything including lessons, delete the database:

rm ~/.devcoach/coaching.db
devcoach setup   # re-creates it
