iterm2-layout

iterm2-layout is a skill for Claude Code from terrylica/cc-skills. It costs 35 tokens per session (1,659 once invoked), scanned A, original, MIT.

A configuration skill for arranging iTerm2, the macOS terminal application, into workspace layouts. It uses TOML, a readable configuration-file format, together with scripts and optional Git worktree discovery.

In plain words
What is it for?
Use it to create or change terminal tabs and panes, set up iTerm2 AutoLaunch, or discover Git worktrees in a workspace layout.
Why use it?
It keeps private workspace paths separate from reusable layout logic and makes repeated terminal setups easier to configure.

    Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.
    Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.
  • medium Rogue Agent · line 71
    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

iterm2-layout scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

iTerm2 Layout Configuration

Configure iTerm2 workspace layouts with proper separation of concerns: private paths in TOML config, publishable code in Python script.

Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.

When to Use This Skill

Use this skill when:

  • Configuring iTerm2 workspace layouts
  • Adding, removing, or modifying workspace tabs
  • Setting up AutoLaunch scripts for iTerm2
  • Configuring git worktree tab auto-discovery

Setup Instructions

First-Time Setup

/usr/bin/env bash << 'CONFIG_EOF'
# 1. Ensure config directory exists
mkdir -p ~/.config/iterm2

# 2. Copy template
cp ~/scripts/iterm2/layout.example.toml ~/.config/iterm2/layout.toml

# 3. Edit with your workspace paths
# Add [[tabs]] entries for each workspace

# 4. Restart iTerm2 to test

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
