isolate-parallel-work SKILL.md skillA

isolate-parallel-work from haiggoh/free-agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add haiggoh/free-agents/isolate-parallel-work@git:20261031.530a28e

Pins git:20261031.530a28e in mdr.lock. Pin the fingerprint instead.

Use BEFORE dispatching work that touches files or requires exclusive access to a server/port. Triggered by the need to run multiple agents concurrently or to prevent clobbering. Do NOT use for verifying output, guarding runtime, or composing payloads.

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

# isolate-parallel-work — prevent clobbering and contention

When multiple agents (local sessions, cloud subagents, or manual edits) work on the same repo or share a server, isolation is mandatory.

## Detect other running sessions
"Look for other sessions" is not actionable. Use signals, not intuition:

1. **Servers and their owners:** list what is actually listening before assuming a port is yours.
   ```bash
   # narrow the grep to whatever port range your launcher scans, not a guessed one
   lsof -nP -iTCP -sTCP:LISTEN | grep -E ':80[0-9][0-9]'
   ```
2. **Which agent sessions are live, and where they point.** Read each candidate process's environment: the
   endpoint variable is the only reliable local-vs-remote tell, because a "this is local" shell flag **leaks**
   into any later process started from the same shell.
   ```bash
   ps eww <pid> | tr ' ' '\n' | grep -m1 '^ANTHROPIC_BASE_URL='
   lsof -a -p <pid> -d cwd -Fn        # what that session is working on
   ```
3. **Catch sessions whose process you mis-matched:** recently-modified transcript files reveal activity your
   process grep missed.
   ```bash
…

How to install

The exact contents, by fingerprint

mdr add haiggoh/free-agents/isolate-parallel-work@sha256:111529ceb72fcae0

The line at the top of this page pins the label git:20261031.530a28e, 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.
