skill

skill is a skill for Claude Code from wavyrai/tmux-ide. It costs 0 tokens per session (4,515 once invoked), scanned B, original, MIT.

A tmux workspace tool for coordinating multiple coding-agent sessions. tmux is a terminal program that keeps several command-line windows and panes in one session.

In plain words
What is it for?
Use it to monitor working, blocked, and finished agents, receive notifications, restore sessions, and create a separate git worktree and adopted session for each branch.
Why use it?
It makes agent activity visible across panes and helps restore the workspace after a crash.

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 B, and why

skill scanned grade B with 1 finding 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 14d 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.

tmux-ide — Claude Code Skill

tmux-ide is the open-source workspace for coding agents, built on tmux. The app (tmux-ide app) shows every agent across local and SSH machines with ground-truth working/blocked/done status, and drives the live tmux session. tmux-ide adopt adds the same status to plain tmux clients as tmux chrome: a status bar, keys and menus, all additive tmux options with no wrapper process. Around both: notifications when an agent needs a human, and crash-proof restore. tmux owns every process and pane, so sessions survive tmux-ide. .tmux-ide/workspace.yml is optional.

When to use

  • User mentions tmux, a dock/status bar over sessions, an agent fleet, or session status
  • User wants live working/blocked/done status across multiple agents or panes
  • You are an agent and want to report your own status so the dock/fleet reflects it (the agent contract, below)
  • Post-crash recovery — a tmux server died and the user wants their fleet + Claude conversations back
  • User wants a git worktree (plus an adopted session) per branch
  • User wants to set up a multi-pane dev workspace with .tmux-ide/workspace.yml

The agent contract

This is the core of tmux-ide. Detection is two-layer, and an agent that reports its own state is the authoritative layer — the dock trusts it over any screen-scraping. If you are an agent running in a tmux pane, self-report by setting a pane-local tmux option:

tmux set-option -p @agent_state "<state>:$(date +%s)"   # state = working | blocked | done | idle

The value is <state>:<unix-epoch>. A working/blocked report older than ~10 minutes is treated as stale (the detector falls back to Layer 2), so long-running agents should re-stamp periodically. Two optional companions:

tmux set-option -p @agent_session_id "<id>"   # your own session id — powers restore --resume-agents
tmux set-option -p @agent_hint claude          # force which agent manifest Layer 2 uses for this pane

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.

skill is a skill published in the GitHub repository wavyrai/tmux-ide (555 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 4,515 tokens. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
