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
# Oneshot End-to-end autonomous workflow that chains research → plan → implement → validate → ship → merge in a single session. All phases run sequentially in the current Claude Code session, invoking skills directly. Context is managed naturally via Claude's automatic compaction, and the thoughts/ system provides persistent handoff documents between phases. > **Legacy mode for the orchestrator (post-2026-06-15).** `oneshot` remains the canonical > single-shot lifecycle for direct user invocation. The orchestrator's default worker dispatch is > also still `oneshot-legacy` — opt in to the per-phase pipeline by setting > `catalyst.orchestration.dispatchMode` to `"phase-agents"` in `.catalyst/config.json`, which runs > nine short-lived `claude --bg` skills (`phase-triage` … `phase-monitor-deploy`) instead of one > long `claude -p` `oneshot` worker. See > [Phase agents](https://catalyst.coalescelabs.ai/reference/orchestration/phase-agents/) for the > pipeline, model assignment, and cost economics. ## Prerequisites ```bash # Resolve the shared catalyst-dev scripts dir (skills live in catalyst-legacy; scripts stay in …

How to install
mdr add coalesce-labs/catalyst/oneshot@sha256:5d55ad5a9ded64a9The line at the top of this page pins the label v3.0.0, 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.
