oneshot-ship（一次性船）

oneshot CLI

Ship code with a single command. oneshot runs a full 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 wants to delegate a coding task
• User wants to run a task 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 live 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

oneshot <repo> "<task>"                 # ship a task
oneshot <repo> <linear-url>            # ship from a Linear ticket
oneshot <repo> "<task>" --bg           # fire and forget
oneshot <repo> "<task>" --local        # run locally, no SSH
oneshot <repo> "<task>" --deep-review  # force exhaustive review
oneshot <repo> "<task>" --model sonnet # override Claude model
oneshot <repo> "<task>" --branch dev   # target a different branch
oneshot <repo> --dry-run               # validate only
oneshot init                           # configure
oneshot stats                          # recent runs + timing

Pipeline

1. Validate: checks the repo exists, fetches latest from origin
2. Worktree: creates a temp git worktree from the target base branch
3. Classify: classifies the task as fast or deep via heuristics + LLM
4. Plan: Claude reads the codebase and CLAUDE.md conventions, outputs an implementation plan
5. Execute: Codex implements the plan. If it times out with partial changes, the pipeline continues
6. Draft PR: Claude creates a branch, commits, pushes, and opens a draft PR
7. Review: Codex reviews the diff. In deep mode it runs an exhaustive review across correctness, security, and code quality
8. Finalize: pushes review fixes and marks the PR ready

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-5.4-mini",
    "reasoningEffort": "xhigh",
    "reviewModel": "gpt-5.4-mini",
    "reviewReasoningEffort": "xhigh",
    "timeoutMinutes": 180
  },
  "stepTimeouts": {
    "planMinutes": 20,
    "executeMinutes": 60,
    "reviewMinutes": 20,
    "deepReviewMinutes": 20,
    "prMinutes": 20
  }
}

Only host is required for SSH runs. Local mode works without a config file.

Flags

Customization

• Put a CLAUDE.md in any repo root. oneshot passes it to Claude and Codex at every step
• Edit prompts/plan.txt, execute.txt, review.txt, pr.txt to change pipeline behavior

Tips

• Use --bg to fire and forget long tasks
• Linear integration moves tickets to "In Review" and comments the PR URL
• Per-step timeouts prevent runaway processes (plan 20m, execute 60m, review 20m, PR 20m)
• Worktree isolation means your main branch is never touched
• Task classification picks fast or deep mode automatically. Use --deep-review to force deep
• Duration estimates come from historical runs per repo (~/.oneshot/history.json)
