Git auto-detected renames to `.claude/tasks/`, so `tasks/` directory removed implicitly at commit time. - If dir persists empty after `git rm`: ask user to run `rmdir tasks` manually. - **Status**: resolved (fixed via `git rm` + rename auto-detection; no `rmdir` needed in practice). ## BLK-003 — `scripts/screenshot.mjs` hardcoded macOS path blocks PNG cards on Linux - **Date**: 2026-05-12 - **Friction**: `/darwin-skill` Phase 3 generates result cards via `node ~/.agents/skills/darwin-skill/scripts/screenshot.mjs `. On Linux: script fails immediately — `require('/Users/alchain/.npm-global/lib/node_modules/playwright/node_modules/playwright-core')` resolves to a non-existent macOS user path. No PNG cards produced; Phase 3 falls back to markdown report only. - **Real cause**: upstream `alchaincyf/darwin-skill` author dev'd on macOS, shipped absolute path to their own homedir's global npm install of playwright. Zero portability layer (no PATH lookup, no `playwright` bare require, no fallback to `npx`). - **Solution**: - Workaround (used 2026-05-12): skip PNG generation, deliver markdown + HTML cards (HTML viewable in browser without playwright). - Local patch: `npm i -g playwright` then replace `require('/Users/alchain/...')` with `require('playwright')`. Two lines edit. - Spec-documented fallback: `npx playwright screenshot "file:///path/to/card.html#" out.png --viewport-size=960,1280 --wait-for-timeout=2000` — works without modifying the file, costs ~150MB chromium download. - PR upstream to `github.com/alchaincyf/darwin-skill` once tested. - **Status**: upstream (third-party skill at `~/.agents/skills/darwin-skill/scripts/screenshot.mjs`, not in any of our repos).
