claude-code-mods

Mods for Claude Code: function-hook plugins that run inside the session and change what you see around the prompt. Each one installs separately — take only what you want.

Built and tested on Claude Code 2.1.296; mods need a version with function-hook plugins (2.1.275 or later). The status line is a plain script and only needs jq.

Mod	What it does
english-coach	Checks the grammar and fluency of each prompt you write and shows corrections, plus a word or expression to learn, in a band above the prompt
toolbar	A Toolbar button under the prompt: model and effort picker, open in VS Code, and a clean view that replaces the work log with a step tracker
statusline	A status line that shows where you are and what you are driving, and a rate-limit row only when a limit needs attention. A script, not a plugin — install it by hand

Install

In a session:

/plugin marketplace add rafagomes/claude-code-mods
/plugin install english-coach@claude-code-mods
/plugin install toolbar@claude-code-mods

Or from a shell:

claude plugin marketplace add rafagomes/claude-code-mods
claude plugin install english-coach@claude-code-mods
claude plugin install toolbar@claude-code-mods

Turn one off with /plugin disable <mod>@claude-code-mods; remove it with claude plugin uninstall <mod>@claude-code-mods. Plugins are installed per profile — set CLAUDE_CONFIG_DIR in front of the commands for each extra profile.

What each mod sends, and where

Both mods make extra model requests on your account. Read this before installing.

english-coach

Each prompt you write is checked for grammar and fluency — phrasing that is correct but not what a native speaker would say — by a parallel Haiku call, so the turn never waits. Corrections appear as colour-coded bullets ([grammar] / [fluency], original → improved, reason) in a dismissable band above the prompt, plus a "Natural:" rewrite when a short message (under 300 characters) has two or more issues. The last line is a "Learn:" tip — one word, phrasal verb or idiom a native speaker would have used in that message, with its meaning — so the band also appears, with only that line, when there is nothing to correct. A bulleted copy is written to the transcript as a log entry for you, not as part of the conversation.

• Checked: prompts typed at the terminal or sent through Remote Control. Prompts from the SDK, background tasks, peers and schedules are not.
• Sent: your own words from the prompt — pasted blocks and fenced code are stripped first — capped at 3,000 characters, one Haiku request per prompt.
• Skipped entirely: slash commands, ! shell lines, and prompts with fewer than four of your own words left after stripping.
• Switched off and on: /english-coach off stops the checks for the rest of the session and takes the band down; /english-coach on resumes them, and with no argument it toggles; anything else changes nothing. Every session starts with it on. With the toolbar mod installed, the same switch is a row in its card.
• Tuned for Portuguese speakers: the coaching prompt describes the writer as a Brazilian software engineer and looks for literal translations and false friends from Portuguese. It works for anyone, but edit SYSTEM in english-coach/hooks/register.tsx to describe yourself.

toolbar

Adds a Toolbar button at the right of the hint row under the prompt (also /toolbar). It opens a card above the prompt to:

• pick the model, the 1M-context variant and the effort — applied with one /model and one /effort when the card closes;
• open the project root in VS Code (runs open -a "Visual Studio Code", so macOS only);
• switch clean view;
• switch the English coach on and off — a row drawn only when the english-coach mod is loaded, which runs its /english-coach command.

Clean view hides the work — tool rows, the spinner line, the turn-duration line, notifications of background tasks that completed — and shows a step tracker of the task list instead: a short heading, Step N of M with a progress bar, and one row per task. Of the model's text, only the answer to your last prompt stays drawn, plus the latest message of a turn a background task started.

• Sent, only while clean view is on: each prompt you send (typed at the terminal, or through Remote Control or the SDK; up to 4,000 characters) goes to Haiku once for the band's 3-to-6-word heading. A turn started by a background task, a peer or a schedule is never sent.
• Added to the system prompt, only while clean view is on: a short section telling the model that only its task list and final message are seen, and to keep both complete. The steps come from the model's own task tools.

Development

claude plugin test english-coach     # run a mod's tests
claude plugin test toolbar
claude --plugin-dir toolbar          # try a mod without installing it

To type-check a mod, load it once (installed, or with --plugin-dir): the engine writes its types and a tsconfig.json into the mod folder (both gitignored). Then run npx tsc -p <mod>.

After editing a mod installed from a local clone (claude plugin marketplace add /path/to/claude-code-mods), /reload-plugins picks up the change.
