svange/ai-new-project

Create a new standardized repository: $ARGUMENTS

Interactive project standup. Determines project shape, creates the repo, configures GitHub settings, scaffolds the pipeline and local config files, and verifies everything is aligned.

Usage Examples

/ai-new-project my-new-lib          # Create repo named my-new-lib, will ask type/language
/ai-new-project                     # Interactive, will ask for all details

---

1. Gather Requirements

Ask the user for each of these. Use $ARGUMENTS as repo name if provided.

Repo name

• Must be lowercase, hyphens allowed, no special characters
• Will be used as GitHub repo name and package name

Type

• library: Publishes artifacts (PyPI, npm). Main-only branch strategy.
• service: Deploys to environments (AWS staging/prod). Dev + main branch strategy.

Ask: "Is this a library (publishes to a registry) or a service (deploys to environments)?"

Language

• python: Uses uv, ruff, mypy, pytest
• typescript: Uses pnpm, biome, tsc, vitest

Ask: "Python or TypeScript?"

Framework (service repos only)

• SAM: AWS Serverless Application Model
• CDK: AWS Cloud Development Kit
• Terraform: HashiCorp Terraform
• Vite: React + Vite frontend
• Next.js: Next.js frontend
• plain: No specific framework

Ask: "Which framework? (SAM/CDK/Terraform/Vite/Next.js/plain)"

Visibility

• private (default for most projects)
• public (open source libraries)

Ask: "Public or private? (default: private)"

---

2. Create Repository

# Create the repo on GitHub
gh repo create <owner>/<repo-name> --<visibility> --clone
cd <repo-name>

# Initialize git if needed
git init
git remote add origin https://github.com/<owner>/<repo-name>.git

For service type, create the dev branch:

# Create initial commit so branches work
git commit --allow-empty -m "chore: initialize repository"
git push -u origin main
git checkout -b dev
git push -u origin dev
git checkout main

Ensure origin/HEAD points to main:

git remote set-head origin main

---

3. GitHub Configuration via ai-gh

Prerequisite: .env file must exist with GH_REPO, GH_ACCOUNT, GH_TOKEN. If missing, help the user create it.

# Standardize repo settings (automerge, merge strategy, branch deletion)
ai-gh config --standardize

# Apply branch rulesets with 4 universal quality gate checks
ai-gh rulesets --apply <library|service>

Note: ai-gh may not yet support the new gate names ("Code quality" instead of "Pre-commit checks") or the service type. If so:

• Use --apply iac as a temporary substitute for --apply service
• Note that rulesets will need updating once ai-gh is updated (see augint-github issues)

Generate pipeline:

ai-gh workflow --type <library|service>

If ai-gh does not yet support --lang, the generated pipeline will be Python-focused. For TypeScript projects, the skill should manually adjust the pipeline after generation.

---

4. Generate Local Configuration Files

Python projects

pyproject.toml - Create with:

• [project] section: name, version = "0.0.0", python requires >= 3.12
• [build-system] with uv_build
• [tool.ruff]: line-length = 100, select = ["E", "F", "I", "W", "B", "C4", "UP", "DTZ"]
• [tool.ruff.lint.isort]: known-first-party
• [tool.mypy]: python_version = "3.12", disallow_untyped_defs = true, warn_return_any = true
• [tool.pytest.ini_options]: testpaths = ["tests"], addopts = "-ra -q --strict-markers"
• [tool.coverage.run]: source = ["src"], omit = ["/tests/"]
• Dependencies: include dev deps for ruff, mypy, pytest, pytest-cov, pre-commit, semgrep, pip-audit, liccheck, pip-licenses, python-semantic-release

Create src/<package_name>/__init__.py with __version__ = "0.0.0". Create tests/__init__.py and tests/unit/__init__.py.

.pre-commit-config.yaml - Copy from python-template.pre-commit-config.yaml in the ai-standardize-repo skill directory. Adjust paths if framework uses SAM (exclude template.yaml from check-yaml).

renovate.json5 - Copy from library-template.json5 or service-template.json5 based on type.

Semantic release config - Append from python-template.toml. Customize:

• tag_format: {repo-name}-v{version}
• version_variables: ["src/{package_name}/__init__.py:__version__"]
• build_command: "uv lock && uv build" for library, "" for service

TypeScript projects

package.json - Create with:

• name, version = "0.0.0"
• scripts: dev, build, test, lint, format, type-check
• devDependencies: biome, typescript, vitest, semgrep (or as CI-only)

tsconfig.json - Strict mode, ESNext target, appropriate module resolution.

biome.json - Standard configuration matching ruff's philosophy (opinionated defaults).

renovate.json5 - Same templates as Python, adapted for npm ecosystem.

.releaserc.json - Copy from node-template.releaserc.json. Customize tag format.

Common files (all languages)

.editorconfig - Copy from editorconfig-template in ai-standardize-repo skill directory.

.gitignore - Generate with:

• Safety: .env, .env.*, *.pem, .claude/settings.local.json
• Python (if applicable): __pycache__/, *.pyc, .coverage, htmlcov/, dist/, build/, *.egg-info/, .mypy_cache/, .ruff_cache/
• TypeScript (if applicable): node_modules/, dist/, build/, .next/, coverage/
• IDE: .vscode/, .idea/
• OS: .DS_Store, Thumbs.db

5. Customize Build Step

The pipeline's "Code quality" job must include the build validation step for the detected framework:

| Framework | Build command | |---|---| | Plain Python library | uv build | | SAM | sam build | | CDK (Python) | cdk synth | | CDK (TypeScript) | cdk synth | | Terraform | terraform init && terraform validate && terraform plan | | Vite / React | npm run build | | Next.js | npm run build | | Plain TS library | npm run build |

Edit the pipeline's code-quality job to include the appropriate build command. If the pipeline was generated by ai-gh, look for a placeholder comment like # Customize build step and replace it.

---

6. AI Tool Scaffolding

Run augint-shell scaffolding to deploy AI tool configurations:

ai-shell init --project <repo-name>

This deploys .claude/skills/, .agents/skills/, ai-shell.toml, and NOTES.md with the correct repo type and skill set.

If ai-shell is not available, manually note that the user should run it later.

---

7. README

Create README.md with:

# {repo-name}

{Description placeholder - update this}

## Pipeline

![Pipeline](https://github.com/{owner}/{repo-name}/actions/workflows/pipeline.yaml/badge.svg)

## Development

{Language-specific development instructions}

## Reports

- [Coverage Report](https://{owner}.github.io/{repo-name}/coverage/)
- [Security Scan](https://{owner}.github.io/{repo-name}/security/)
- [License Compliance](https://{owner}.github.io/{repo-name}/compliance/)

For libraries, add:

## Installation

pip install {repo-name}

---

8. Initial Commit and Push

git add .
git commit -m "feat: initial project scaffold"
git push -u origin main

For service repos:

git checkout dev
git merge main
git push -u origin dev
git checkout main

---

9. Verify

Run verification:

ai-gh status --type <library|service> --verbose

Check:

• All 4 quality gate status checks are configured in rulesets
• Auto-merge is enabled
• Pipeline file exists with correct job names
• Local config files are present

Report final status. If any issues remain, list them with guidance.

---

Error Handling

• gh CLI not authenticated: ask user to run gh auth login
• ai-gh not installed: skip GitHub config steps, note manual setup needed
• .env missing GH variables: help user create it from .env.example or prompt for values
• Repo already exists: ask if user wants to standardize existing repo instead (suggest /ai-standardize-repo)
• Network errors: retry once, then report and continue with local-only setup
• Framework detection failed for service: ask the user which framework
