Smooth ride for Claude Code

Run ten Claude Code sessions at once and never lose track of them.

/plugin marketplace add isene/cc-smooth
/plugin install cc-smooth@cc-smooth

Then add fleet for the screen that shows every session. What changes on day one:

• Claude refuses five risky shell commands and asks before sudo.
• With /output-style cc-smooth:plain, answers give the verdict first, stay under 12 lines, and number each question, so you reply "3 yes".
• An answer that breaks those rules goes back for a rewrite first.
• With fleet, one screen shows which session works and which one waits for you, and sessions send each other messages.

The plugin has six parts.

Part	What it does	Cost
Guard	Refuses five kinds of shell command, and asks before sudo	About 7 ms per shell command
Prose check	Checks text written to .md and .txt files	About 7 ms per edit; 50 ms for a .md or .txt file
Answer check	Sends an answer that breaks the plain style back for one rewrite	About 0.2 s per answer under plain; 50 ms under another style
Output style plain	Short answers in plain English, the verdict first	No run time; some words in every request
fleet hooks	Hand messages between sessions and keep open items, when fleet is installed	About 5 ms per prompt and per answer without fleet
Starter CLAUDE.md	Rules for simplicity, privacy and checking the work	No run time; read on every turn once copied

The guard

Claude Code runs it before every shell command. It refuses:

• timeout 30 make: set the Bash tool's own time limit instead.
• pkill and killall: they can stop programs Claude did not start.
• a bare git stash: it hides all your changes, including another session's. git stash push -m <why> <paths> still works.
• printing a .env file with cat, head, less and the like.
• printing a file from your secrets folder, if you name one.

It also asks before any sudo, unless your sudoers file lets that command run without a password.

Each refusal tells Claude why, so it picks another way at once. A word counts only where a command starts: echo pkill and a commit message about git stash pass.

To test it, run scripts/guard-test.sh. It sends 31 commands through the guard and prints all cases right.

The prose check

After Claude writes a .md or .txt file, the check reads the new text. It flags:

• an em-dash;
• a sentence over 22 words, or a paragraph over 5 lines;
• an opener that announces instead of saying ("Let me be clear");
• a word from phrasebook.txt, with the plain word to use instead.

Claude gets the list and fixes it. Code blocks, tables and quotes are skipped. Edit phrasebook.txt to add the words that read as jargon to you. scripts/stylecheck <file> runs the same check by hand.

It needs python3 and jq.

The answer check

Under the plain style, a hook reads each answer when the turn ends. It sends the answer back when it finds:

• more than one sentence before the details start;
• more than 20 lines, not counting tables and code;
• text after the Your move: lines, or a question with a label in front;
• an ETA given as a length, or already past;
• an ETA with nothing in the background to wake Claude when the work ends;
• anything the prose check flags, such as an em-dash.

Claude rewrites only the flagged parts. The second stop of a turn always passes, and so does any error in the hook. Under another style it does nothing. scripts/answer-test.sh runs nine cases and prints all cases right.

The output style

Switch it on with /output-style cc-smooth:plain, the name Claude Code gives a plugin's style. Answers lead with the verdict in one sentence, stay under 12 lines, and end with what you must decide or do. It keeps Claude Code's own coding rules.

fleet, for many sessions at once

fleet is a terminal screen that lists every Claude Code session on the machine: which one works, which one waits for you, and what each one still asks of you. The plugin wires it in, so you only install fleet itself:

curl -L -o ~/.local/bin/fleet https://github.com/isene/fleet/releases/latest/download/fleet-linux-x86_64
chmod +x ~/.local/bin/fleet

Builds for ARM Linux and for macOS are on the releases page. On a Mac, fleet leaves out workspaces and raising windows, which need X11. With fleet on your PATH, the plugin's hooks:

• hand a session the messages that wait for it, when you type a prompt and when its turn ends;
• keep each session's numbered questions and Your move: lines until it closes them;
• mark a session that waits at a permission dialog.

A message is a file in ~/.fleet/bus/<session id>/, and fleet's m key writes one. If you added fleet's hooks to settings.json by hand before, remove them, or they run twice.

The starter CLAUDE.md

templates/CLAUDE.md is a starting point for ~/.claude/CLAUDE.md. Copy it and cut what does not fit you. Claude Code does not load it from the plugin by itself.

Install

The two lines at the top install it. To try it from a clone of this repo instead, without installing it:

claude --plugin-dir .

When the plugin is switched on, Claude Code asks for your secrets folder. Leave it empty to guard .env files alone.
