agent-isolation skillA

agent-isolation is agent-read markdown (skill) from vmobifystudio/app-dev-team: 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..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
