Oneshot Ship

oneshot CLI

Ship code with a single command. oneshot CLI runs a full autonomous pipeline: plan (Claude) -> execute (Codex) -> review (Codex) -> PR (Claude). Works over SSH to a remote server or locally with --local.

When to use this skill

• User wants to ship a code change to a repository without manual coding
• User wants to automate the plan/implement/review/PR workflow
• User mentions "oneshot" or "oneshot CLI" or wants autonomous code shipping
• User wants to delegate a coding task to run on a remote server or locally

Installation

bun install -g oneshot-ship

Setup

Run oneshot init to configure SSH host, workspace path, API keys, and model preferences. Config is saved to ~/.oneshot/config.json.

Repos on the server should be organized as <org>/<repo> under the workspace path:

~/projects/
  my-org/my-app/
  my-org/my-api/

Server prerequisites

• Bun
• Claude Code CLI
• Codex CLI
• GitHub CLI (authenticated)
• ANTHROPIC_API_KEY and OPENAI_API_KEY in environment

Usage

Basic usage

oneshot <repo> "<task>"

With Linear ticket

oneshot <repo> <linear-url>

Fetches the ticket as context and updates its status after the PR is created.

Local mode

oneshot <repo> "<task>" --local

Runs the pipeline directly on the current machine instead of SSH-ing to a server. Requires Claude Code CLI, Codex CLI, and GitHub CLI installed locally.

Background mode

oneshot <repo> "<task>" --bg

Fire and forget -- runs detached on the server (SSH mode only).

Dry run

oneshot <repo> --dry-run

Validates the repo exists without running the pipeline.

Override model

oneshot <repo> "<task>" --model sonnet

Pipeline steps

1. Validate -- checks the repo exists, fetches latest from origin
2. Worktree -- creates a temp git worktree from origin/main, auto-detects and installs deps (bun/pnpm/yarn/npm)
3. Plan -- Claude reads the codebase and CLAUDE.md conventions, outputs an implementation plan
4. Execute -- Codex implements the plan
5. Review -- Codex reviews its own diff for bugs, types, and security issues
6. PR -- Claude creates a branch, commits, pushes, and opens a PR

The worktree is cleaned up after every run.

Configuration

~/.oneshot/config.json:

{
  "host": "user@100.x.x.x",
  "basePath": "~/projects",
  "anthropicApiKey": "sk-ant-...",
  "linearApiKey": "lin_api_...",
  "claude": { "model": "opus", "timeoutMinutes": 180 },
  "codex": { "model": "gpt-5.3-codex", "reasoningEffort": "xhigh", "timeoutMinutes": 180 },
  "stepTimeouts": {
    "planMinutes": 20,
    "executeMinutes": 60,
    "reviewMinutes": 20,
    "prMinutes": 20
  }
}

Only host is required. Everything else has defaults.

Flags

Customization

• Drop a CLAUDE.md in any repo root to enforce conventions -- oneshot passes it as context to both Claude and Codex
• Edit prompts/plan.txt, execute.txt, review.txt, pr.txt to change pipeline behavior

Tips

• Use --bg for long-running tasks so you can fire and forget
• Linear integration auto-moves tickets to "In Review" and adds a PR comment
• Per-step timeouts prevent runaway processes (defaults: plan 20min, execute 60min, review 20min, PR 20min)
• oneshot CLI creates isolated worktrees so your main branch is never affected
