recursive-worktree

name	recursive-worktree
description	Use when starting any recursive-mode requirement to set up an isolated git worktree. Required before implementation phases: create an isolated workspace, verify a clean baseline, and keep main/master clean.

recursive-worktree

Purpose

Use this skill at the start of a recursive-mode run to set up an isolated worktree before Phase 1+ work begins.

The canonical overall workflow still lives in /.recursive/RECURSIVE.md. This skill covers only the worktree-isolation discipline for 00-worktree.md.

Hard Rule

Do not proceed with recursive-mode phase work until:

1. A feature-branch worktree exists.
2. The worktree directory is git-ignored if it lives inside the repo.
3. Project setup has completed.
4. A clean or explicitly acknowledged baseline test state has been recorded.

Default Location Order

Use this priority:

1. Existing .worktrees/
2. Existing worktrees/
3. A preference documented in repo instructions
4. Ask the user
5. Default to .worktrees/

Global fallback location:

• ~/.config/recursive-mode/worktrees/<project-name>/

Main Branch Protection

If the current branch is main or master, default to creating a worktree on a feature branch:

git worktree add .worktrees/<run-id> -b recursive/<run-id>
cd .worktrees/<run-id>

If the user explicitly insists on main-branch work, record that exception in 00-worktree.md.

Minimum Phase 0 Checklist

00-worktree.md must cover:

• selected worktree location
• git-ignore verification
• branch name and worktree path
• setup commands executed
• baseline test command and result
• normalized diff basis fields including Baseline type, Baseline reference, Comparison reference, Normalized baseline, Normalized comparison, and Normalized diff command
• explicit note that subsequent phases run from the worktree
• the required ## TODO heading from the scaffold

Suggested Commands

Check branch:

git branch --show-current

Check ignore status:

git check-ignore -q .worktrees || git check-ignore -q worktrees

Create worktree:

git worktree add .worktrees/<run-id> -b recursive/<run-id>

Setup Guidance

Run the setup command that matches the repo:

• Node.js: npm install
• Rust: cargo build
• Python: pip install -r requirements.txt or project-specific install
• Go: go mod download
• Maven: mvn compile -q
• Gradle: ./gradlew compileJava
• .NET: dotnet restore

Then run the baseline test command appropriate to the project and record the result in 00-worktree.md.

Router State In Worktrees

Before delegated or routed work runs from an isolated worktree, verify the router files inside that same worktree:

test -f .recursive/config/recursive-router.json
test -f .recursive/config/recursive-router-discovered.json

Test-Path .recursive/config/recursive-router.json
Test-Path .recursive/config/recursive-router-discovered.json

If the controller/source repo has a configured router policy or discovery inventory and the worktree lacks it, sync both files into the worktree before resolving or invoking routed roles. Preserve user edits to the worktree policy; when changing bindings, prefer recursive-router-configure over hand edits.

recursive-router-discovered.json is local discovery state and may be untracked. Its absence in a fresh worktree is expected, but it is still not safe to resolve an external role from stale assumptions. Refresh it with python ./scripts/recursive-router-probe.py --repo-root . --json from the worktree, or copy the current inventory from the controller/source repo when that is the intended policy basis.

Record the router policy path, discovery path, validation/probe command, and resulting route decision in 00-worktree.md or in the delegated action record before accepting routed work.

Output Contract

Write the artifact to:

• /.recursive/run/<run-id>/00-worktree.md

Use feature branches named:

• recursive/<run-id>

Routing Awareness

If this skill uses delegated review or any other routed external model to validate worktree setup, baseline verification, or branch safety, re-read:

• /.recursive/config/recursive-router.json
• /.recursive/config/recursive-router-discovered.json

immediately before choosing that CLI/model, and honor the routed policy or explicit fallback instead of hardcoding a reviewer model.

Integration

• Invoke this skill before AS-IS analysis and planning.
• After Phase 0 is lock-valid, continue the run from the worktree context.
• Keep later phases, including STATE.md, DECISIONS.md, and memory updates, on the same feature branch until merge time.
