Safety notes

This skill recommends terminal and Claude Code configuration changes; it must not edit dotfiles, keybindings, hooks, themes, or tmux settings without showing the proposed diff first.
`/terminal-setup` writes terminal or editor keybindings and may adjust integrated-terminal settings; run it in the host terminal and record what changed before relying on it.
tmux passthrough allows escape sequences to reach the outer terminal; enable it deliberately, especially on shared, remote, or security-sensitive hosts.
Notification hooks can execute local commands when Claude needs attention; keep them simple, review command paths, and avoid hooks that send prompts or logs to third-party services.
Fullscreen rendering, theme files, status lines, and keybinding changes should be treated as reversible local UI preferences, not fixes for model quality or project bugs.

Privacy notes

Terminal settings, tmux files, keybinding files, status line commands, and hook snippets can expose usernames, hostnames, project paths, shell aliases, secrets in environment commands, and internal repository names.
Notification commands and status line scripts may reveal task names, working directories, git branches, model names, costs, or local operational context.
Remote terminal and SSH notification behavior can surface session activity on a local desktop; confirm the user is comfortable with that visibility.
Public PR or issue notes should summarize symptoms and redacted settings, not paste complete dotfiles, shell history, terminal transcripts, or private hook scripts.

Prerequisites

Claude Code installed and runnable in the terminal, editor terminal, SSH session, or tmux/screen environment being reviewed.
The user's operating system, terminal emulator, shell, Claude Code version, and whether Claude Code is running locally, remotely, or inside tmux.
Permission to inspect redacted terminal settings, `~/.claude/settings.json`, `~/.claude/keybindings.json`, `~/.tmux.conf`, and notification hook snippets when relevant.
A concrete ergonomics symptom, such as Shift+Enter submitting, missing alerts, scrollback jumping, unreadable colors, Vim mode confusion, or shortcut conflicts.

About this resource

Knowledge Freshness

This capability pack is grounded in Claude Code terminal configuration, interactive mode, keybindings, fullscreen rendering, settings, status line, skills, and extension-overview documentation verified on 2026-06-10. Prefer live official docs over remembered shortcuts or terminal-specific behavior when reviewing new Claude Code releases.

Scope Note

This is not another terminal setup guide. Use it as a reusable review workflow when a user reports that Claude Code is hard to operate in their terminal and you need to classify the problem, choose the smallest reversible fix, and document verification. For step-by-step prose setup, the existing guide at content/guides/terminal-tmux-and-vim-setup-for-claude-code.mdx remains the adjacent reference.

Core Workflow

Inventory the environment: operating system, terminal emulator, shell, editor integrated terminal if any, SSH or local session, tmux/screen layer, Claude Code version, and whether /terminal-setup has already run.
Classify the primary symptom before changing settings: multiline input, Option/Meta shortcuts, notifications, tmux passthrough, rendering/scrollback, theme/readability, status line, Vim mode, or custom keybindings.
Check universal multiline fallbacks first. Confirm whether Ctrl+J or backslash followed by Enter inserts a newline before recommending terminal changes for Shift+Enter.
For Shift+Enter problems, verify the terminal support lane and whether /terminal-setup belongs in the host terminal rather than inside tmux or screen.
For macOS Option-key shortcuts, verify whether the terminal sends Option as Meta or Esc+. Treat editor-integrated terminals separately from native terminals.
For tmux, review allow-passthrough, extended-keys, and terminal-feature configuration, then verify newlines, progress updates, and notifications from inside a fresh tmux pane.
For missing alerts, distinguish terminal bell, desktop notifications, operating-system notification permission, tmux passthrough, and Notification hooks. Keep hooks minimal and auditable.
For display flicker, scrollback jumps, mouse behavior, or long-session rendering issues, evaluate fullscreen rendering before changing unrelated shell, font, or theme settings.
For color/readability issues, separate Claude Code themes, custom theme JSON, terminal color schemes, and status line output. Do not treat a theme mismatch as a model or prompt problem.
For Vim mode or shortcut conflicts, inspect Claude Code interactive mode and keybinding configuration before editing terminal emulator shortcuts.
Recommend one reversible change at a time, include rollback instructions, and define a concrete verification prompt or keypress sequence.

Capability Scope

Multiline input and submit/newline separation.
Shift+Enter, Option/Alt/Meta, and custom keybinding triage.
tmux passthrough and extended-key review.
Terminal bell, desktop notification, and Notification-hook routing.
Fullscreen rendering, scrollback, mouse, and display-stability checks.
Theme, custom status line, Vim mode, and readability review.
Privacy-safe summaries of local terminal configuration.

Compatibility

Native

Claude Code / Claude: use as an Agent Skill when reviewing a user's live terminal setup, terminal configuration files, or Claude Code UI behavior.

Manual Adaptation

Codex, Cursor, Windsurf, and Generic AGENTS workflows: use the workflow as a deterministic checklist for diagnosing Claude Code terminal ergonomics in a repository, support ticket, or onboarding runbook.

Required Inputs

Symptom, exact key sequence, and expected versus actual behavior.
Terminal emulator, shell, operating system, editor-integrated terminal status, SSH/local context, and tmux/screen status.
Claude Code version and whether the issue reproduces in a clean terminal tab.
Redacted relevant snippets from terminal settings, settings.json, keybindings.json, ~/.tmux.conf, notification hooks, or status line scripts.

Production Rules

Do not conflate terminal transport bugs with Claude model quality or project behavior.
Prefer built-in, documented shortcuts before asking the user to customize terminal bindings.
Run /terminal-setup only when it matches the terminal lane and the user accepts that it writes local configuration.
Never edit tmux, keybinding, theme, status line, or hook files without showing the proposed change and rollback path.
Keep notification hooks local and narrow unless the user explicitly approves a third-party notification route.
Redact paths, hostnames, usernames, tokens, hook commands, and branch names before posting public summaries.

Review Matrix

Symptom	First route	Safer first check
Enter submits when user wanted a newline	Multiline input	Try `Ctrl+J` and backslash plus Enter before config edits
Shift+Enter does not insert a newline	Terminal setup	Check terminal support lane and whether `/terminal-setup` already ran
Option+Enter or Option+P does nothing on macOS	Option/Meta	Verify Option-as-Meta or Esc+ in the active terminal profile
Shift+Enter and notifications fail inside tmux	tmux	Review passthrough and extended-key lines in `~/.tmux.conf`
No alert when Claude needs attention	Notifications	Distinguish desktop notification, terminal bell, OS permission, and hooks
Text flickers or scrollback jumps	Rendering	Try fullscreen rendering and check integrated-terminal GPU settings
Colors or footer are hard to read	Theme/status line	Separate Claude Code theme, terminal theme, and status line script output
Vim motions or custom shortcuts conflict	Interactive mode/keybindings	Inspect Claude Code keybindings before changing terminal global shortcuts

Output Contract

Environment inventory and primary symptom lane.
Evidence reviewed, including redaction notes.
Minimal change recommendation with exact file, setting, or in-product command.
Verification checklist for the relevant keypresses, notification, rendering, or tmux behavior.
Rollback instructions.
Privacy-safe summary suitable for an issue, onboarding doc, or support handoff.

Duplicate Check

An adjacent guide exists for terminal, tmux, and Vim setup, but no skills entry provides a reusable Claude Code terminal ergonomics audit workflow. This entry is intentionally a capability pack with an output contract and review matrix, not a duplicate prose guide.
