yjcli

CLI that scaffolds YJ platform folders, services, and AI agent wiring (Cursor, Claude Code, Codex).

Templates, skills, and root make files ship inside the package and are copied into the target repo. Standing agent guidance lives in AGENTS.md only (CLAUDE.md is a mirror).

Install

uv tool install yjcli
# pin a version:
uv tool install yjcli==0.0.5

yjcli --version
yjcli -h

Upgrade / remove:

uv tool upgrade yjcli
uv tool uninstall yjcli

Quick start

uv tool install yjcli
cd /path/to/your-repo
yjcli init --all
yjcli service add -p backend -n api
# edit AGENTS.md, then:
yjcli sync agents

make backend                 # start all backend services
make backend NAME=api        # start one service

Platforms

Use with -t / --type (repeatable on init / platform add):

backend · backend-service · frontend · mobile-app · pc-app · cli · browser-extension

What init creates

• AGENTS.md, CLAUDE.md (mirror of AGENTS.md)
• Skills under .cursor/skills/, .claude/skills/, .agents/skills/ (Codex)
• Claude settings.json
• Root Makefile, make.bat, TOOLS.md, .gitignore
• Selected platform roots (*/scripts/run.sh / run.bat)

The root Makefile / make.bat is the repository-owned extension point for project automation. Projects may add commands such as <platform>-build or <platform>-deploy and reuse optional NAME=<service> selection. Defining and implementing init/install/build/deploy behavior is the project's responsibility; yjcli does not generate action scripts. Do not add per-service scripts/ directories or per-service Makefiles.

Operating rules (skill routing, output discipline) are in AGENTS.md — not in .cursor/rules / .claude/rules.

Run (make)

Platform targets are discovered from */scripts/run.sh (after init / platform add). Each service declares its local command as RUN_COMMAND in .env.local-dev. New services include .env.local-dev, .env.development, .env.production, and .env.examples. Only .env.local-dev and .env.examples are required; development/production may be removed and other .env.<environment> files may be added. Commit .env.examples only. The platform runner executes that repository-owned declaration instead of inferring npm, uv, Go, or another language/runtime from project manifests.

make <platform>                 # all services under that platform (concurrent)
make <platform> NAME=<service>  # one service
make help

Sync

Edit AGENTS.md only; do not edit CLAUDE.md by hand. Use migrate when upgrading from older yjcli layouts (rules era).

Options

• --type / -t — platform type (backend, frontend, …) on init / platform add.
• --platform / -p — existing platform root on service add.
• --name / -n — service/app name on service add.
• --path <dir> — target repo root (default: current directory).
• --force / -f — overwrite existing root/agent files without prompting (init only).

Notes

• platform add only creates platform roots (no services, no skills/Makefile — use service add / sync).
• service add needs the platform root first (init or platform add).
• Non-interactive: pass -t / --all / -p / -n as needed.
• doctor checks the installed package assets, not your target repo.
• sync skills / sync all remove legacy .cursor/rules and .claude/rules if present.
• sync migrate also overwrites AGENTS.md from the package (destructive); requires --yes when non-interactive.
