taskmaestro

A tmux-based coordinator for running several Claude Code workers at the same time, with each worker isolated in its own Git worktree. tmux is a terminal tool for managing multiple panels, and a worktree is a separate working copy of a Git repository.

In plain words
What is it for?
Use it to divide a development job across multiple workers, track their results, and coordinate work in parallel.
Why use it?
It keeps concurrent development tasks separated while letting you assign work, monitor progress, send instructions, and stop workers from one control panel.

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 D, and why

taskmaestro scanned grade D with 2 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 2d 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

TaskMaestro — tmux 패널 오케스트레이터

현재 tmux 세션의 기존 패널들에서 Claude Code를 병렬로 실행하고, 이 패널(지휘자)에서 제어한다. 각 패널은 독립된 git worktree에서 작업하며, 지휘자가 작업 지시, 상태 감시를 수행한다.

전제 조건: 지휘자(이 Claude Code)가 tmux 패널 중 하나에서 실행 중이어야 하며, 나머지 패널들이 이미 열려있어야 한다.

Arguments 파싱

$ARGUMENTS를 파싱하여 서브커맨드와 인수를 분리한다:

  • start [--repo <path>] [--base <branch>] [--panes <1,2,3>] [--review-pane] [--no-review-pane]
  • assign <패널번호> "<작업 지시>"
  • status
  • watch
  • send <패널번호> "<텍스트>"
  • stop [패널번호|all]

서브커맨드에 해당하는 섹션으로 이동한다.

현재 tmux 환경 감지

모든 서브커맨드에서 먼저 실행:

# 현재 tmux 소켓, 세션, 윈도우 정보를 자동 감지
TMUX_SOCKET=$(tmux display-message -p '#{socket_path}')
# 소켓 이름 추출 (경로에서 마지막 부분)
SOCKET_NAME=$(basename "$TMUX_SOCKET")
SESSION=$(tmux display-message -p '#{session_name}')
WIN_IDX=$(tmux display-message -p '#{window_index}')
MY_PANE=$(tmux display-message -p '#{pane_index}')

tmux 명령어에서 -L 플래그는 소켓 이름을 사용한다. tmux -L "$SOCKET_NAME" send-keys ... 형태로 사용.


Worker Completion Signaling (RESULT.json)

워커가 작업을 완료하면 .taskmaestro/wt-N/RESULT.json 파일을 생성하여 지휘자에게 결과를 알린다. 이 파일은 watch 모드의 1차 감지 수단이며, capture-pane은 fallback으로만 사용한다.

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.

taskmaestro is a skill published in the GitHub repository JeremyDev87/codingbuddy (31 stars, last pushed 4mo ago), licensed MIT. It adds 28 tokens to every session and 11,250 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it D with 2 findings (reads agent configuration directories, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
