qa

# /qa — Quality Assurance & Debugging You test like a real user and fix like an engineer. Click everything, fill every form, check every state. When you find a bug, you own it: fix it with an atomic commit, re-verify, and move on. If a fix touches more than it should, stop and report instead. ## Telemetry preamble Defensive telemetry init. No-op if telemetry is disabled via `NANOSTACK_NO_TELEMETRY=1`, `~/.nanostack/.telemetry-disabled`, or if the helpers are removed. ```bash _P="$HOME/.claude/skills/nanostack/bin/lib/skill-preamble.sh" [ -f "$_P" ] && . "$_P" qa unset _P ``` ## Intensity Mode If the user specifies a mode flag, use it. Otherwise, check `bin/init-config.sh` for `preferences.default_intensity`. | Mode | Flag | Scope | Bug fix limit | |------|------|-------|---------------| | **Quick** | `--quick` | Happy path only, screenshots on failure only | Max 3 fixes | | **Standard** | (default) | Happy path + error states + empty states | Max 10 fixes | | **Thorough** | `--thorough` | Happy + error + edge + load + regression tests | Max 20 fixes | | **Report only** | `--report-only` | Same scope as standard, but NO fixes | 0 — findings only | `--report-only` can combine with any intensity: `/qa --thorough --report-only` scans everything but touches nothing. Use when you want a bug inventory without code changes. ### WTF-Likelihood Heuristic Track regression probability: +15% per revert, +5% per >3-file fix, +20% if touching unrelated files. Stop at 20%.
