What it does
Worktree Parallel is an agent skill from D-Robotics/moss. How to run writable sub-agents in isolated git worktrees and merge their lease patches
Its SKILL.md is about 310 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Git worktrees and Subagents. The licence is MIT.
When your agent uses it
- Tasks that involve Git worktrees
- Tasks that involve Subagents
Example prompts
- “/worktree-parallel”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- In fan_out_subagents, give each implementation task scope: "full", declared writePaths, and worktree: true (or set…
- Each child then works in its own git worktree under .moss/worktrees/ — concurrent writers cannot see or stomp each other.
- On completion the child's changes are collected as a binary patch under .moss/patches/.patch; its summary ends with [worktree lease=…
- Merge leases back with merge_subagent_patch (leaseId + patchId from the child result). Merging uses git apply --3way, so changes in…
- Merge order matters when tasks touch the same files: merge one, verify, then the next.
- Worktrees are cleaned up automatically after patch collection; the patch files remain for audit.
What it can do on your machine
Read from SKILL.md and the folder at commit 58e7f61. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Worktree Parallel loads about 313 tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 141 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

merge_subagent_patch(leaseId + patchId from the child result). Merging usesgit apply --3way, so changes in different regions of a file compose; a same-region collision returnsmerge_conflictwith the conflicting paths — resolve manually, do not force. - Merge order matters when tasks touch the same files: merge one, verify, then the next.
- Worktrees are cleaned up automatically after patch collection; the patch files remain for audit.
