Written for Claude Code and Codex and OpenCode: PostToolUse hook event, but also the file is AGENTS.md. Also seen: mentions Claude Code; mentions AGENTS.md.

This is Mahir-Isikli/claude-code-tmux's own configuration. It tells Claude Code, Codex and OpenCode how to work on claude-code-tmux itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude-code-tmux configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/mahirisikli/Git/Personal/claude-code-tmux.

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 C, and why

claude-code-tmux AGENTS.md scanned grade C 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 2mo 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

claude-code-tmux agent notes

What this repo is

claude-code-tmux provides durable tmux control for interactive Claude Code sessions.

It ships three integration surfaces:

  1. ccmux CLI for humans and agents.
  2. Pi extension tools: ccmux_start, ccmux_send, ccmux_steer, ccmux_status, ccmux_capture.
  3. Native Pi provider: claude-code-tmux/opus and claude-code-tmux/sonnet.

The package is published on npm and GitHub:

  • npm: claude-code-tmux
  • GitHub: https://github.com/Mahir-Isikli/claude-code-tmux

Current working release

As of the native Pi tool bridge work, the working npm release is 0.5.0.

Important fixes in 0.2.1:

  • Auto-detect and accept Claude Code workspace trust prompts in provider mode.
  • Wait for Claude Code to be ready before sending the first provider prompt.
  • Verify the pasted job id is visible in the tmux pane before submitting.
  • Retry paste if tmux drops it.
  • Submit with C-m instead of literal Enter.
  • Provider mode requires a done JSON with final_response and returns that to Pi.

Important additions in 0.3.0:

  • Generated Claude Code hook settings per ccmux session.
  • bin/ccmux-hook.mjs command hook recorder.
  • Hook events stored under ~/.pi/ccmux/events/<job-id>.jsonl.
  • ccmux events --job <job-id> and ccmux events --session <name> for inspection.
  • Provider mode starts Claude Code with hooks enabled.
  • Provider streams hook lifecycle/tool progress as thinking/progress deltas while preserving the final response text.
  • Provider matrix script under scripts/provider-matrix.mjs.

Important additions in 0.4.0:

  • ccmux_replay_tool_result shadow replay tool.
  • Claude Code PostToolUse and PostToolUseFailure events are replayed into Pi as tool calls/results without re-running the underlying operation.
  • Matrix asserts PiReplayToolResult events.

Important additions in 0.5.0:

  • bin/ccmux-pi-tool.mjs bridge command for Claude Code to request native Pi tools.
  • Provider prompt includes a pi_native_tool_bridge command pattern with available Pi tools.
  • Provider intercepts pending Pi tool requests and emits the requested native Pi tool call.
  • Provider writes the real Pi tool result back for the blocking Claude Code bridge command.
  • Matrix asserts PiNativeToolRequest and PiNativeToolResult events.

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.
