/sniper-init

Initialize SNIPER v3 framework in the current project.

Process

1. Check Existing State

• If .sniper/config.yaml exists, ask user: "SNIPER is already initialized. Reinitialize? (existing config will be backed up)"
• If reinitializing, copy .sniper/config.yaml to .sniper/config.yaml.bak

2. Auto-Detect Project

Scan the project directory to detect:

Language (check in order):

• tsconfig.json or *.ts files → TypeScript
• package.json → JavaScript
• pyproject.toml or requirements.txt → Python
• go.mod → Go
• Cargo.toml → Rust
• pom.xml or build.gradle → Java
• Fall back to --language argument or ask user

Package Manager:

• pnpm-lock.yaml → pnpm
• yarn.lock → yarn
• bun.lockb → bun
• package-lock.json → npm
• uv.lock → uv
• poetry.lock → poetry

Framework:

• next.config.* → Next.js
• nuxt.config.* → Nuxt
• vite.config.* → Vite
• angular.json → Angular

Test Runner:

• vitest.config.* → Vitest
• jest.config.* → Jest
• pytest.ini or conftest.py → Pytest

Commands (from package.json scripts or Makefile):

• Look for test, lint, build, typecheck scripts

3. Gather User Input

Ask the user (with auto-detected defaults pre-filled):

1. Project name (default: directory name)
2. Project type (saas, api, mobile, cli, library, monorepo)
3. One-line description
4. Max concurrent teammates (default: 5)
5. Confirm detected stack

4. Scaffold Structure

Create the following directory structure:

.sniper/
  config.yaml              ← Generated from template + user input + auto-detection
  checkpoints/
  gates/
  retros/
  self-reviews/
  checklists/              ← Copied from @sniper.ai/core/checklists/
  memory/
    learnings/             ← Unified learning store (replaces signals/)
    signals/               ← Legacy — kept for backward compat, migrated by memory-curator
    archive/               ← Deprecated learnings archived here
.claude/
  agents/                  ← Copied from @sniper.ai/core/agents/
  settings.json            ← Merge hooks from @sniper.ai/core/hooks/
CLAUDE.md                  ← Generated from template

5. Apply Plugins

If plugins are configured (or auto-detected):

1. Read each plugin's plugin.yaml
2. Merge plugin commands into config
3. Copy plugin mixins to .claude/personas/cognitive/
4. Merge plugin hooks into .claude/settings.json

6. Confirm

Display summary:

• Files created/modified
• Detected stack
• Suggested next step: "Run /sniper-flow to start your first protocol"

Rules

• NEVER overwrite existing project source files
• ALWAYS back up existing config before reinitializing
• ALWAYS show the user what will be created before doing it
• Respect .gitignore — add .sniper/checkpoints/ and .sniper/gates/ if not present
