What is worktree-task-plugin CLAUDE.md?

Repository instructions for a Claude Code plugin that starts coding-agent sessions in separate Git worktrees—isolated copies of a repository—and manages them through tmux terminal sessions.

Use them when delegating work to Claude Code or Codex, checking a running task, recovering from rate limits or timeouts, or managing its plugin files and scripts.

They describe how large coding tasks are split among separate agent sessions and how those sessions are launched, monitored, resumed, and cleaned up.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00793	$0.00793
Opus 5.5	$0.00317	$0.00317
Sonnet 5.5	$0.00159	$0.00159

Security

Grade A, and why

worktree-task-plugin CLAUDE.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 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.

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.

Project Overview

A Claude Code plugin that enables spawning autonomous agent sessions in separate git worktrees via tmux. Manages large coding tasks that would otherwise overflow context by delegating phases to subagents.

├── commands/*.md                 # Slash command definitions (/worktree-task:*)

└── references/*.md               # Prompt templates for spawned agents

Core Flow

launch.py - Creates worktree + tmux session, launches agent (Claude Code or Codex), sends task prompt
status.py - Captures tmux pane output, shows git info from worktree
resume.py - Detects error type (rate_limit, api_error, timeout), sends recovery message
cleanup.py - Kills tmux session, optionally removes worktree
merge.py / rebase.py - Spawns Claude in tmux to auto-resolve git conflicts

Key Design Patterns

tmux as state: Sessions track running tasks, pane capture provides status
Worktrees for isolation: Each task gets its own working directory
Template substitution: $TASK_DESCRIPTION, $WORKTREE_DIR in references/*.md
Hook-based updates: on-session-start.py checks GitHub Releases API for updates (24h cache)

# Test a script directly

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.
