Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00043 | $0.01162 |
| Opus 5 | $0.00022 | $0.00581 |
| Sonnet 5 | $0.00009 | $0.00232 |
| Haiku 4.5 | $0.00004 | $0.00116 |
Grade A, and why
iterm2 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 9d 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.

The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Iterm2
Complete reference for iTerm2 terminal emulator and tmux terminal multiplexer on macOS. Covers keyboard shortcuts, configuration, tmux integration, and productivity workflows.
Workflow Routing
When executing a workflow, do BOTH of these:
-
Call the notification script (for observability tracking):
~/.claude/Tools/SkillWorkflowNotification WORKFLOWNAME Iterm2 -
Output the text notification (for user visibility):
Running the **WorkflowName** workflow from the **Iterm2** skill...
| Workflow | Trigger | File |
|---|---|---|
| SetupTmux | "setup tmux", "configure tmux" | workflows/SetupTmux.md |
| TmuxSession | "tmux session", "attach session", "detach" | workflows/TmuxSession.md |
| TroubleshootTmux | "tmux not working", "fix tmux" | workflows/TroubleshootTmux.md |
Examples
Example 1: Split terminal into multiple panes
User: "How do I split my terminal in iTerm2?"
→ References Shortcuts.md
→ Explains Cmd+D (vertical) and Cmd+Shift+D (horizontal)
→ Shows navigation with Cmd+Option+Arrow
Example 2: Setup tmux with iTerm2 integration
User: "How do I use tmux with iTerm2?"
→ Invokes SetupTmux workflow
→ Explains tmux -CC control mode
→ Shows native window integration benefits
Example 3: Manage persistent sessions over SSH
User: "Keep my terminal running after disconnect"
→ Invokes TmuxSession workflow
→ Creates named session with tmux new -s
→ Shows how to reattach after disconnect

What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

iterm2 is a skill published in the GitHub repository julianobarbosa/claude-code-skills (10 stars, last pushed 13d ago), licensed MIT.
