Lythoskill Red Green Release

Red-Green Release Workflow

> No tag without LGTM. Every change is a self-archiving patch. Every state is rollback-able.

Typical Scenarios

This skill shines when the agent does not have direct filesystem or git access to the user's project. Typical setups:

• Web chat + Repomix: User pastes a Repomix dump of their codebase into a web chat. The agent proposes changes as pr-*.sh heredoc patches. The user copies the patch locally and runs bash pr-*.sh.
• Distributed / async review: Patches are posted in issues, emailed, or shared via web UI for a human to review and apply manually.
• No git on target: Environments (e.g., bare-metal servers, deployed configs) where git revert is unavailable — .bak files provide rollback.

In these scenarios the agent cannot git commit, git diff, or write files directly. The heredoc patch is the only viable delivery format.

Core Principles

1. User acceptance drives releases — "LGTM" / "对了" / "就是这样" → then and only then commit + tag.
2. Atomic patches — Each iteration = one pr--.sh with heredoc content replacement.
3. Self-archiving — Patch copies itself to archived-patches/ and deletes itself after execution.
4. Rollback-ready — Every patch backs up originals before modifying. Rollback = restore backup.

Workflow (4 Phases)

Phase 1 — Plan: Understand requirement, describe approach, user confirms design. Phase 2 — Create Patch (dry-run): Write pr--.sh containing backup + heredoc replacement + self-archive logic. Show to user for review. User says "apply it" → proceed. Phase 3 — Apply & Test: Execute patch (bash pr-*.sh). Restart service. User tests. If issues → back to Phase 2 with a new patch. Iterate until green. Phase 4 — Accept & Tag: User says LGTM →

git add -A
git commit -m ""
git tag -a  -m ""

Patch File Format

Naming

pr--.sh

Forbidden words in description: final, done, fix, ok. These words encourage skipping the red-green test cycle by implying pre-verified success.

Template

#!/bin/bash
# PR: -
# 1. Create archive directory
mkdir -p archived-patches
# 2. Backup current files (for rollback)
cp src/target.ts "archived-patches/target.ts.$(date +%Y%m%d).bak"
# 3. Apply changes (declarative full-file replacement via heredoc)
cat > src/target.ts  ⚠️ Heredoc delimiter (`PATCH_EOF`) must be quoted in the `cat` command to prevent variable expansion. See [references/archive-format.md](./references/archive-format.md) for multi-file patches and escaping rules.
