What is github-issue-worktree-agent?

A manager for Git worktrees assigned to GitHub issues. A worktree is a separate working folder linked to a Git branch, so issue work can be isolated from the main checkout.

Use it to create, list, or remove isolated worktrees for issue branches, with folders based on issue numbers.

It prevents changes for one issue from dirtying or interfering with the main working directory.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/richfrem/agent-plugins-skills

npx agentmods add skills/richfrem/agent-plugins-skills/github-issue-worktree-agent

Made for: Claude Code.

Or install dev-utils, the plugin that ships this one along with the rest of its 19 skills.

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	$0.00084	$0.00703
Opus 5.5	$0.00034	$0.00281
Sonnet 5.5	$0.00017	$0.00141
Haiku 4.5	$0.00008	$0.00070

Security

Grade A, and why

github-issue-worktree-agent 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 17d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/issue_worktree_manage.py, tests/test_issue_worktree.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

GitHub Issue Worktree Agent (github-issue-worktree-agent)

Provisions and manages isolated git worktrees (.worktrees/issue-NNN) for clean issue execution branches.

Critical Constraints

Scope Boundary: USE ONLY for worktree lifecycle operations. DO NOT USE for PR lifecycles (use github-issue-pr-lifecycle-agent) or issue logging (use github-issue-agent).
Standard Location: Worktrees must strictly reside within .worktrees/issue-NNN relative to repository root.
Safe Teardown: Check git status prior to removal; never force-prune uncommitted work without confirmation.
Branch Tracking: Branch naming must consistently map to the issue identifier (issue-NNN).

Quick start

# Provision isolated worktree for Issue #123
python3 plugins/dev-utils/skills/github-issue-worktree-agent/scripts/issue_worktree_manage.py \
  create --issue 123 --base main

# List active worktrees
python3 plugins/dev-utils/skills/github-issue-worktree-agent/scripts/issue_worktree_manage.py list

# Clean up worktree after resolution
python3 plugins/dev-utils/skills/github-issue-worktree-agent/scripts/issue_worktree_manage.py \
  remove --issue 123

Workflow

Phase 1: Workspace Inspection: Check for existing worktree directories or branch name collisions.
Phase 2: Worktree Provisioning: Spawn isolated worktree at .worktrees/issue-NNN tracking trunk.
Phase 3: Implementation Context: Guide agent execution to occur within the isolated worktree directory.
Phase 4: Teardown & Pruning: Confirm committed state, prune worktree directory, and clean local branch.

Verification

# Verify active worktree state
python3 plugins/dev-utils/skills/github-issue-worktree-agent/scripts/issue_worktree_manage.py list

# Audit skill compliance
python3 plugins/agent-scaffolders/scripts/audit_skill.py plugins/dev-utils/skills/github-issue-worktree-agent --mode source

Files

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

github-issue-worktree-agent is a skill published in the GitHub repository richfrem/agent-plugins-skills (7 stars, last pushed yesterday), licensed MIT. It adds 84 tokens to every session and 703 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-12.
