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

tmux-ide AGENTS.md 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 13d 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.

tmux-ide

A visual, agent-aware IDE for ordinary tmux sessions. .tmux-ide/workspace.yml is an optional declarative layout preset.

Quick Start

tmux-ide              # Visual tmux app; configless by default
tmux-ide app [session] # Explicit app entry; optionally open a live session
tmux-ide init         # Scaffold .tmux-ide/workspace.yml (auto-detects stack)
tmux-ide inspect      # Show resolved config + live tmux state
tmux-ide stop         # Kill session
tmux-ide attach       # Reattach to running session

.tmux-ide/workspace.yml Format

version: 1
name: project-name # tmux session name

before: pnpm install # optional pre-launch hook

terminal:
  theme: # optional color overrides
    accent: colour75
    border: colour238
    bg: colour235
    fg: colour248
  rows:
    - size: 70% # row height percentage
      panes:
        - title: Claude 1 # pane border label
          command: claude # command to run (optional)
          size: 50% # pane width percentage (optional)
          dir: apps/web # per-pane working directory (optional)
          focus: true # initial focus (optional)
          env: # environment variables (optional)
            PORT: 3000

    - panes:
        - title: Dev Server
          command: pnpm dev
        - title: Shell

The project file is optional: the app discovers and manages ordinary live tmux sessions without one. Legacy ide.yml files are still supported through a compatibility adapter. Use tmux-ide migrate --dry-run to preview conversion and tmux-ide migrate --write to create .tmux-ide/workspace.yml.

WorkspaceConfigV1 can declare harnesses, agents, and missions data, but mission runtime wiring is future work. Do not add legacy team, pane role/task, sidebar, or orchestrator fields to .tmux-ide/workspace.yml.

Widget Pane Types

panes:
  - title: Explorer
    type: explorer # explorer | changes | preview | config | sidebar
    target: src/ # optional target path

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.
