Claude Code Terminal Ergonomics Capability Pack Skill
Expert Claude Code terminal ergonomics capability pack for auditing multiline input, Option/Meta shortcuts, tmux passthrough, notifications, fullscreen rendering, themes, status lines, Vim mode, and custom keybindings before a user blames Claude for terminal behavior.
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.

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.
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.
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

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

✓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.
✓This skill recommends checkpoint actions; it must not run `/rewind` restore or summarize without explicit user approval.
Restore code and conversation reverts both files and chat history to a prior prompt; confirm the target checkpoint before acting.
Restore code alone keeps conversation but reverts file edits; restore conversation alone keeps current files but rewinds chat.
Summarize compresses conversation segments without changing files on disk; it is not a substitute for git revert when bash commands modified files.
Checkpointing does not track files changed by bash commands such as `rm`, `mv`, or `cp`; use git or manual recovery for those paths.
✓Deep links pre-fill prompts but never auto-send; users must press Enter after reviewing the external-link warning.
Untrusted pages can craft malicious prompts; treat every deep link like untrusted input until a human reviews it.
Prompts over 1,000 characters show an extended warning; require scroll review before sending long links.
Network and UNC paths are rejected for cwd; use absolute local paths or repo slugs instead.
If both cwd and repo are passed, cwd wins even when the path does not exist; validate parameters deliberately.
Organizations can disable handler registration with disableDeepLinkRegistration in settings or managed policy.
✓Subagent transcripts may contain tool output with repository paths, credentials, or customer data.
Resuming a subagent retains full prior tool history—confirm scope before continuing destructive work.
This skill reviews transcripts; it does not delete files unless you explicitly apply documented retention settings.
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.
✓The /rewind menu lists every user prompt in the session, which may expose internal task names, credentials pasted in prompts, or customer context.
Restored prompts reappear in the input field and may contain sensitive instructions that should be redacted before sharing screens.
Session transcripts persist with checkpoints for up to 30 days by default; treat resumed sessions as containing prior sensitive content.
Public support notes should describe the recovery lane and checkpoint choice, not full prompt text or complete file diffs.
✓Deep link URLs embed prompt text in query parameters, which may expose incident details, customer names, or internal service names in browser history, chat logs, or ticketing systems.
repo resolution uses the most recently used local clone path, which can reveal directory layout on shared screens via the welcome header.
Runbooks pasted into GitHub-rendered Markdown lose clickable claude-cli:// links; code-block copies still expose full URLs to readers.
Public runbooks should use redacted example prompts and generic repo slugs unless the audience is internal-only.
✓Transcript jsonl files under ~/.claude/projects/ may include PII from read tools and MCP outputs.
External summaries should describe categories of exposure, not paste raw transcript lines.
Agent IDs in transcripts can correlate sessions—redact before sharing outside the team.
