Use when executing implementation plans with independent tasks in the current session.
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
> **Related skills:** Need an isolated workspace? `/skill:using-git-worktrees`. Need a plan first? `/skill:writing-plans`. Done? `/skill:finishing-a-development-branch`. Reached via the auto-chain from `/skill:writing-plans` (not a direct human entry point; direct invocation stays possible for recovery, e.g. re-running after a STOP). # Subagent-Driven Development Execute a plan by dispatching a **fresh subagent per task**, with two-stage review after each: spec compliance first, then code quality. **Core principle:** Fresh subagent per task + two-stage review = high quality, fast iteration. If a tool result contains a ⚠️ workflow warning, stop immediately and address it before continuing. Gauntlet execution dispatches are foreground: set top-level `async: false` on every implementation, review, conformance, retry, and prose-described dispatch. Preserve parallel `tasks` batches and chain groups. `forceTopLevelAsync` is incompatible; an unexpected async handle means stop and report, never poll or relaunch. See [pi-cohort dispatch configuration](https://github.com/jjuraszek/pi-cohort/blob/main/doc/configuration.md). ## Why Subagents …

How to install
mdr add jjuraszek/pi-gauntlet/subagent-driven-development@sha256:e625de7ca4b376c5The line at the top of this page pins the label git:20261020.c79e361, 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.
