Need help deploying ftk-perf?
Chalk Labs sets up agents like this inside real teams: connected to your tools, tested on your data, with a human in the loop where it matters.
Install
Works with Claude Code, Claude apps, Codex, Cursor, Gemini CLI, GitHub Copilot, VS Code, OpenCode, Goose, Windsurf. Read the repository before you give any tool access to your data.
npx agentmarket install skill/adiwirya-ftk-perf
Asks which of your tools to add it to (Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop) and shows the change first. See https://agentmart.dev/cli.

SKILL.md (first lines)
No fix without a measurement. Debug-mode observations are not evidence. Resolve the toolkit root from `toolkitPath` in `~/.config/flutter-tools-kit/ftk-settings.json`, then read `knowledge/performance.md` from it — it is the playbook; this skill is the loop. ## Loop 1. **Reproduce & measure:** run `flutter run --profile`, drive the slow interaction, capture DevTools Performance data (frame times, dominating phase) and rebuild stats. Record the baseline numbers. 2. **Identify the single top offender** from the data — name the widget/provider/operation and which playbook section applies. 3. **Fix that one thing** per the playbook. 4. **Re-measure the same scenario.** Improved → keep and repeat from 2 if still janky. Not improved → revert and re-diagnose; never keep speculative changes. 5. **Stop** when frames are within budget (~16ms) for the scenario or remaining gains cost architecture-level rework — then report options instead of silently rebuilding. Report: baseline vs final numbers, each change with its measured effect, and any reverted attempts (so they are not retried later).
