Day 06 — AI Tools

Developer track

Claude Code Desktop core

Flagship features + parallel work — and Developer Checkpoint 2

Artifacts: from a session, publish a PR walkthrough artifact; share with a peer.
/loop: /loop 15m on your open PR (built-in maintenance prompt), then a custom /loop 5m check the deploy; write a loop.md for the repo.
Remote Control: start a session at your desk (/rc), connect from your phone via claude.ai/code, send a steer from the phone.
"Ultracode" family: ultrathink keyword on a gnarly bug; /effort levels on the same bug, compare; note plan-tier availability.

Exercise

One artifact + one loop run + one phone steer, screenshotted to the channel.

Parallel isolated sessions on two tickets (git worktrees); watch both in agent view.
Subagents intro (course: Introduction to subagents); cloud session for a long task; close the laptop and check on it from claude.ai/code.

Checkpoint 2Developer track

Two parallel sessions both merged.
One plan-mode change steered via diff comments.
One artifact.
One Remote Control steer.
One /loop run.

BA/QA track

Claude Desktop for planning

BA deep work / QA test design + Dispatch — and BA/QA Checkpoint 2

BA: competitor/regulation research in Cowork; spreadsheet of findings; decision doc.
QA: test matrices from the Day-5 ticket packs — happy paths, edge/negative cases, data variations; test plan artifact per feature.

Exercise

(QA) Draft 2 bug reports in the reproduce-ready template from seeded bugs; devs confirm they can reproduce from the report alone.

Dispatch from Cowork (if plan allows): kick a task from the mobile app, get the push notification. Otherwise: Remote Control tour with a dev buddy.

Checkpoint 2 · BA

One 90-minute ticket pack from a raw request (story + criteria + questions + artifact) judged by a dev for implementability.

Checkpoint 2 · QA

One reviewed test matrix + 2 reproduce-ready bug reports.

Skills today

Developer track

Artifacts: Live shareable PR walkthroughs / investigation timelines

How to set up

Already built in — in a Code session, ask Claude to publish the walkthrough or timeline as an artifact; it gets its own page and share link. Self-contained output can also become one on its own.
/loop: Scheduled re-runs: watch a PR, babysit CI, morning maintenance

How to set up

Already built in — type /loop 5m check the deploy (interval + task) in a Code session. It re-runs while the session is open; press Esc to stop it.
Remote Control (/rc): Steer a session from your phone

How to set up

Already built in — type /rc in a Code session and accept the one-time confirmation, then steer it from the Claude phone app or at claude.ai/code. Requires a Pro, Max, Team, or Enterprise login (API keys not supported).
ultrathink + /effort levels: Deep reasoning spent only where it pays (the “ultracode” ask in real form)

How to set up

Already built in — put ultrathink in your prompt for one-off deep reasoning, or type /effort to pick an effort level (confirm the cache warning if one appears).
Git worktrees + parallel sessions: Two tickets in flight, two isolated agents, zero crosstalk

How to set up

Already built in — run claude --worktree ticket-123 in the repo; run it again with a different name in a second terminal for a second isolated session. The repo needs at least one commit.
Subagents: Delegate bounded investigation while the main session codes

How to set up

Already built in — Claude delegates bounded research on its own to built-in agents (Explore, Plan); you'll see them appear under the prompt. No install; custom ones later live in .claude/agents/.

BA/QA track

Test-matrix design: Systematic coverage before automation

How to set up

Nothing to install — a testing practice: pick the dimensions (inputs, state, environment), enumerate the combinations, drop the impossible ones. A doc or spreadsheet is all you need.
Reproduce-ready bug reports: Devs reproduce from the report alone

How to set up

See Day 2 for the setup steps.
repro-template bug skill: Reproduce-ready format, automated

How to set up

Nothing to install beforehand — the team authors this skill during Day 7+; until then, follow the Day-2 report structure by hand.
Dispatch (phone-kicked Code sessions, push alerts; Pro/Max only): Hand a task over while commuting
How to set up
1. Install the Claude app on your phone (iOS or Android) — in a Code session, /mobile shows a QR link.
2. Keep the Claude Desktop app open and signed in on your computer.
3. In the phone app, message Dispatch your task — it becomes a Code session on your machine and pushes an alert when it finishes or needs you. Pro or Max plan required.
