mergetrain: Instructions file for Claude Code

CLAUDE.md

mergetrain CLAUDE.md is an instructions file for Claude Code from yongjip/mergetrain. It costs 1,218 tokens per session, scanned A, original, MIT.

An instruction file for operating mergetrain, a local queue that serializes code branches through merging, testing, pushing, and verification. It defines how coding agents hand off committed work and how an authorized runner deploys it.

In plain words
What is it for?
Use it to prepare a task branch, commit its changes, inspect mergetrain’s health or queue status, enqueue an exact commit, and distinguish agent handoff from the separately authorized merge-and-deploy process.
Why use it?
It reduces conflicts when several worktrees or task branches need to enter one deployment flow. It also sets safety checks around reuse of validation and unattended deployment.

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Codex.

This is yongjip/mergetrain's own configuration. It tells Claude Code how to work on mergetrain itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mergetrain configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mergetrain CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CLAUDE.md — operating mergetrain from Dispatch

This repository ships mergetrain, a local deploy train for coding-agent worktrees. Keep phone-facing results short and actionable. Setup and phrasebook details live in docs/mobile.md.

Shared operating protocol

Purpose: Serialize committed local task branches through one merge/test/push/verify runner.

Existing queues and explanations

  • Existing mergetrain repositories keep status → enqueue → stop even for one branch. Queue counts alone do not establish health, runner ownership, or recovery needs; read health, state, and next_action together.
  • For explanation-only requests, read the skill documentation when permitted and explain the procedure without Git or product commands. Distinguish hypothetical steps from observed state.

Current command reference

  • The v3 core commands are init, status, enqueue, validate, deploy, and inspect.
  • Start with mergetrain status --json. Use mergetrain status --diagnose --json only for configuration, Git, runtime, or lock detail, and mergetrain inspect JOB_ID --json for job evidence. doctor is removed, not an alias for status --diagnose.
  • Confirm uncertain syntax with the installed mergetrain --version and command-specific --help only when command execution is permitted. Otherwise use this reference and identify missing details; do not invent commands or copy older syntax from unversioned web results. Inspection and next_action do not authorize recovery or deployment.

Rules

  1. Work on a task-specific branch and worktree.
  2. Commit a clean HEAD before handing work off.
  3. Read mergetrain status --json and follow its next action before changing queue state.
  4. Enqueue every named finished branch in the requested order using only its task and branch; mergetrain resolves the worktree and captures the exact commits. Stop after the last successful enqueue unless the user explicitly authorized validation or the complete validation-and-deployment workflow.
  5. Never push configured integration refs directly. One authorized runner owns validation and deployment; recovery and destructive actions require their stated approval.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
