Use before spawning any agent that writes files, and by every developer/fixer agent as its first and last action. Gives each agent its own git worktree, forbids blanket staging, and requires confirming a mutation actually landed. Triggers from /app-build, /app-audit, parallel-orchestrator, and any parallel agent launch. Prevents parallel agents corrupting each other's work.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Agent isolation

Parallel agents that share one working tree corrupt each other. Not "might" — *do*.

The default developer method is: write the files, then `git checkout -b feat/APP-NNN` and commit.
Run two of those concurrently in one tree and the sequence is:

```
dev A writes  ui/TodoListUiState.kt          (on main, untracked)
dev B writes  data/InMemoryTodoRepository.kt (on main, untracked)
dev A runs    git checkout -b feat/APP-001   -> B's file comes along
dev A runs    git add . && git commit        -> A ships B's half-finished work
dev B runs    git checkout -b feat/APP-002   -> from A's branch, inheriting A's commit
```

Both branches are now wrong, and neither agent can tell. Worse, this is silent: every agent
reports `DONE`, tests pass, and the review reads a diff that contains someone else's changes.

**A read-only agent is not exempt.** A verification agent sharing a working tree once left a
billing file with its guest-purchase guard deleted. Only explicit-path staging kept it out of the
commit. One `git add -A` ships a removed billing guard.

## Rule 1 — one worktree per WRITING AGENT, always

How to install

The exact contents, by fingerprint
mdr add vmobifystudio/app-dev-team/agent-isolation@sha256:48f54352abc4e6c4

The line at the top of this page pins the label git:20260807.98058c3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
