sprint

Orchestrate one large milestone as staged brainstorm/plan/execute cycles in a living sprint doc. Runs on Claude Code or Oh My Pi (OMP).

• Decomposes a multistage milestone into stages; resumes across sessions from the doc

• Per stage: brainstorm spec → write plan → executor implements → dedicated sprint-reviewer gate (parallel specialists, fix, re-review) → verify → land

• Keeps the main session a lean conductor; nests each stage through a sprint-stage-runner subagent (Claude Code: probed once per sprint; OMP: requires task.maxRecursionDepth >= 3) or falls back to one subagent per step

• Delegates implementation to an executor: native subagents on Claude Code or OMP (recommended default), plus mimo or codex on Claude Code only

• Engine chosen by arg (/sprint native|mimo|codex) or an interactive runtime-supported menu; executor and review models are explicit choices recorded for resume

• Depends on mimo-code for the Claude Code mimo engine; OMP currently offers native only. Matt Pocock's grilling, codebase-design, and diagnosing-bugs skills are strongly recommended but optional; sprint retains built-in brainstorming, planning, diagnosis, and runtime-native SDD paths.

mimo-code

Delegate write-capable coding sessions to the mimo CLI (Xiaomi's opencode fork), keeping Claude the conductor.

• Offloads implementation to mimo on a chosen provider/model + effort
• Runs each session in a sonnet subagent — main context stays lean
• Captures every session id to a parallel-safe file for resume (--session, never --continue)
• Resolves the model from mimo models ∩ authenticated providers and asks you
• Per-handle O_EXCL lock keeps concurrent sessions isolated

Installation

claude plugin marketplace add https://github.com/onsails/cc
claude plugin install rust-dev@onsails-cc

claude plugin install mimo-code@onsails-cc

Installing sprint auto-installs its mimo-code dependency. To also use the codex engine, install the official Codex plugin from its own marketplace (optional):
