parallel SKILL.md skillA
parallel from ericrisco/rsc-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ericrisco/rsc-harness/parallel@git:20261003.f0c84d6Pins git:20261003.f0c84d6 in mdr.lock. Pin the fingerprint instead.

Use when two or more pieces of work are genuinely independent — disjoint files, no shared state, no ordering edge — and should fan out across subagents, then be gathered and reconciled under a combined test suite. Decides WHAT can run concurrently; NOT the isolation it runs in (that is `worktrees`), NOT the per-unit TDD loop (that is `implement`).
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
# parallel — fan out independent work, then reconcile *Parallelism is a property of the work, not a wish. Prove the pieces are disjoint, dispatch one subagent per piece with a self-contained brief, then gather and reconcile before anyone calls it done.* This is an **on-demand process skill** in the SDD chain. You reach it from `implement` (or any phase) when the work in front of you splits into pieces that could each be handed to a different person who never talks to the others. It owns one discipline: **partition → dispatch → gather → reconcile**. It does *not* own the work inside each piece — a subagent building a module still runs its own red → green → refactor loop from `implement`; this skill only orchestrates the fan-out. It also does not own the *place* the work runs: a clean branch or checkout to work in is `worktrees`. `parallel` decides **what can run at the same time**; `worktrees` provides **the isolation it runs in**. …

How to install
mdr add ericrisco/rsc-harness/parallel@sha256:b6d7bd5f2bbf491aThe line at the top of this page pins the label git:20261003.f0c84d6, 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.
