Measure the token/cost/time efficiency of AI coding-agent work — per session, per role, per day, and per individual sub-agent — with every dollar metered by ccusage. Use when the user asks "what did this cost", cost per session/role/test case, which role/sub-agent burned the most, tool-call/skill/time breakdowns, "before vs after" cost comparisons, or wants to audit AI spend over time.
Per-role persistent memory — durable facts, preferences, decisions, and a daily log, as plain markdown. Use when the user says "remember this" or "log this", asks "what did you learn yesterday", or whenever you discover something worth keeping across sessions.
UI/E2E test automation with Playwright MCP. Use when the user asks to "test the UI", "automate browser tests", "check the page", "take a screenshot", "run Playwright", "write E2E tests", or anything about browser-based testing.
Turn a vague bug report into precise, repeatable steps with evidence and a CONFIRMED / CANNOT-REPRODUCE / PARTIAL verdict. Use when a bug is unclear or unconfirmed and needs reproduction before RCA or any fix. Reproduction and documentation only — does not fix code.
Generate AGENTS.md and .agents/ configuration files for a new project. Use when the user asks to "seed the project", "onboard this repo", "generate project config", "create AGENTS.md", or after the scout has explored the codebase.
Use when a TMS test case needs to become an automated test, or when automating a regression batch — "automate TC-NNN", "convert this case to a framework test", any flow from a manual case to green framework tests. Pluggable TMS (Zephyr/TestRail/Xray/Azure/markdown).

Testing-grade browser automation using Chrome controlled through the Chrome DevTools
Protocol. All interactions use real CDP Input domain events (mouse coordinates,
key events) — not synthetic JS .click(). Zero external dependencies beyond
Node 22's built-in WebSocket.
Scripts live in the scripts/ directory alongside this SKILL.md:
chrome-launcher.sh — Start/stop/status Chrome with remote debuggingcdp.mjs — Full CDP client with 50+ commandsNo npm install required. Uses Node 22 built-in WebSocket.
