workspace-isolation SKILL.md skillA
workspace-isolation from baphuongna/pi-crew is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add baphuongna/pi-crew/workspace-isolation@git:20260911.c97bc57Pins git:20260911.c97bc57 in mdr.lock. Pin the fingerprint instead.

Workspace isolation boundaries. When NOT to use: concurrent edits within same repo (use worktree-isolation); non-git projects.
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
# workspace-isolation
pi-crew enforces workspace isolation so that agents, runs, and live sessions from one project folder cannot be accessed from another. The workspace boundary is `manifest.cwd` — the directory where a run was initiated.
## Workspace Boundary Definition
**`manifest.cwd`** is the canonical workspace root. Every run record carries the directory where it was created.
**Why it matters:** Pi can have multiple workspace folders open simultaneously. Without isolation, an agent from workspace A could be steered/controlled from workspace B.
**Rules:**
- Every run's `manifest.cwd` is set at creation time
- Every live agent handle carries `workspaceId = manifest.cwd`
- Widget queries filter by `manifest.cwd`
- API operations reject cross-workspace access
## Live Agent Workspace Check
`LiveAgentHandle.workspaceId` field (added to prevent cross-workspace access):
```typescript
interface LiveAgentHandle {
// ... other fields
/** Workspace where this agent was spawned — used for session-scoped visibility. */
workspaceId: string;
}
```
**Enforcement in `api.ts`** (team-tool operations):
```typescript
// list-active-live-agents: filter by workspace

How to install
mdr add baphuongna/pi-crew/workspace-isolation@sha256:42cf0070a7ee24a3The line at the top of this page pins the label git:20260911.c97bc57, 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.
