Every command, verified against the docs, with when to reach for it. The everyday moves, the model picker, the meters that keep your plan alive, and the power moves. Save it, steal it, ship faster.
/rewindRoll the chat and your code back to any earlier point, even after you wiped it with /clear. Good for: a bad edit, a wrong turn, a wiped chat.
Needs the app. Start a task from your phone and it keeps running on Anthropic's servers after your screen sleeps. Good for: away from your desk, a long task, on the go.
claude --channels plugin:imessageEarly access. Text Claude from iMessage or Telegram and it makes real changes in your project, no laptop in hand. Good for: a quick fix, no laptop, on your phone.
/goal <condition>Set a finish line like all tests pass, or the page loads clean, and it works until that is true. Good for: a big cleanup, clearing a backlog, no babysitting.
/simplify <folder>Strip duplication and over-engineering from any folder and apply the fixes. Cleanup only, nothing new added. Good for: a messy folder, over-engineering, dead code.
/modelThe picker: Fable 5 for the hardest problems, Opus for deep work, Sonnet 5 as your default, Haiku for cheap and fast. Swap mid-chat, nothing lost. Good for: picking a brain, swapping mid-chat.
/model fableAccess varies by plan. When it keeps going in circles, switch to Fable 5 for the hard part, then switch back. Good for: stuck in circles, the hardest bugs, big decisions.
Fable 5 reads dense dashboards, error screens and diagrams, so you can debug from a picture. Good for: error screens, dashboards, diagrams.
/model opusplanOpus does the thinking, then hands the typing to cheaper Sonnet. Quality plans without the full bill. Good for: a big feature, hard planning, cost control.
Sonnet 5, built in. Sonnet 5 holds your entire project in its head at once. Just ask it to read everything. Good for: a whole codebase, the system view, big refactors.
/fastCosts extra credits. About 2.5x quicker replies when you are in a hurry. It burns credits faster, so flip it off after. Good for: live debugging, a tight deadline.
/effort highDeep thinking for hard problems, quick answers for small ones. You choose per task. Good for: a security audit, deep design, a quick rename.
/usagePro plan and up. See which features are burning through your monthly limit. Good for: plan running low, what costs most, trimming usage.
/contextWhen Claude slows down, see what is filling its head: your files, the chat, the tools. Good for: it feels slow, a stuffed session, what to trim.
/cd ../other-projectJump to another project mid-chat and it still remembers everything. No restart. Good for: two projects, shared code, side quests.
claude -p --fallback-model sonnet,haikuScripts only. For scripted runs: if a model is overloaded it switches to a backup and keeps going. Good for: overnight jobs, CI runs, automations.
model: haikuIn .claude/agents/x.md. A helper agent is a mini Claude for one job. One line in its file runs it on cheap Haiku, pennies per task. Good for: searches, checks, file lookups.
