+# MON-04: CLI Telemetry System (Opt-in)
+
+## Context
+You are an autonomous agent working on the **backant-cli** repository — a Python CLI tool (`ant` command) built with Click and Pydantic. Your task is to build an opt-in anonymous telemetry system using PostHog Python SDK.
+
+## Repository Structure
+- `ant/cli.py` — main CLI entry point (Click-based)
+- `ant/commands/` — CLI subcommands
+- `ant/utils/` — utility modules
+- `setup.py` — package config (entry point: `ant=ant.cli:main`)
+- `requirements.txt` — dependencies
+
+## Instructions
+
+### 1. Add PostHog Python SDK
+- Add `posthog` to `requirements.txt`
+- Update `setup.py` install_requires
+
+### 2. First-Run Consent Prompt
+- Show: "Help improve BackAnt by sharing anonymous usage data? (y/n)"
+- Store consent in `~/.backant/config.json`
+- Respect `DO_NOT_TRACK` env var
+
+### 3. Anonymous Device ID
+- Generate UUID, store in `~/.backant/config.json`
+- Use `hashlib.sha256(machine_id + salt)` for PostHog `distinct_id`
+- **NEVER send PII**
+
+### 4. Create `ant/utils/telemetry.py`
+Track events via PostHog Python SDK:
+- `cli_installed` — first run
+- `command_executed` — command name + success/failure only
+- `api_generated` — first successful generation
+- `error_occurred` — error type only, no stack traces
+- `session_duration`
+- `onboarding_completed`
+
+### 5. Click Integration
+- Add Click callback/decorator wrapping commands with telemetry
+- Add `--no-telemetry` global flag
+- Add `--privacy` flag that prints telemetry info
+
+### 6. Async & Non-Blocking
+- Use PostHog batching + `atexit` flush
+- Never block CLI operation
+- Silent fail on network errors
+
+### 7. Privacy Documentation
+- Create `docs/telemetry.md`
+- Update README.md
+
+## Acceptance Criteria
+- [ ] First-run prompt works and saves preference
+- [ ] `DO_NOT_TRACK` env var respected
+- [ ] Events reach PostHog when consent given
+- [ ] CLI performance unchanged (async, non-blocking)
+- [ ] `--no-telemetry` and `--privacy` flags work
+- [ ] Privacy docs written
+
+## Guardrails
+- **NO PII** — no file paths, project names, usernames, IPs, stack traces
+- Must be opt-in, NOT opt-out
+- Do NOT block CLI operations
+- Do NOT modify existing command behavior
+- Do NOT hardcode API keys
+- This is **Python** — use `posthog` Python SDK
+- Run existing tests before creating PR

+# CLAUDE.md - Agent Instructions for backant-cli
+
+This file provides instructions for AI agents working on this codebase.
+
+## Project Overview
+
+- **Name**: backant-cli
+- **Type**: Python CLI tool
+- **Purpose**: Generate backant backend projects
+- **Package Manager**: pip/setuptools
+- **Entry Point**: `ant` command (`ant/cli.py`)
+
+## CRITICAL: Pre-Commit and CI Workflow
+
+**NEVER push without running local checks first.**
+
+### Required Workflow for All Code Changes
+
+```
+1. Make changes
+2. Run local checks: ./scripts/ci/run-checks.sh quick
+3. Fix any issues: ./scripts/ci/run-checks.sh fix
+4. Re-run checks until passing
+5. Commit and push
+```
+
+### Local Check Commands
+
+```bash
+# Quick checks (ALWAYS run before committing)
+./scripts/ci/run-checks.sh quick
+
+# Full checks including tests
+./scripts/ci/run-checks.sh all
+
+# Auto-fix linting/formatting issues
+./scripts/ci/run-checks.sh fix
+
+# Specific checks
+./scripts/ci/run-checks.sh lint     # Ruff linting only
+./scripts/ci/run-checks.sh format   # Black formatting only
+./scripts/ci/run-checks.sh test     # Pytest only
+```
+
+## Code Standards
+
+### Python
+
+- **Formatter**: Black (default settings)
+- **Linter**: Ruff
+- **Tests**: pytest
+- **Source Location**: `ant/`
+
+```bash
+# Format
+black ant/
+
+# Lint
+ruff check ant/ --fix
+
+# Test
+pytest -v
+```
+
+## Development Setup
+
+```bash
+# Install in editable mode with dev dependencies
+pip install -e ".[dev]"
+
+# Or install dev tools separately
+pip install ruff black pytest
+```
+
+## Directory Structure
+
+```

+## DO NOT
+
+- Push without running `./scripts/ci/run-checks.sh quick`
+- Skip linting/formatting checks
+- Commit secrets or credentials
+
+## DO
+
+- Run local checks before every commit
+- Use `./scripts/ci/run-checks.sh fix` to auto-fix issues
+- Write tests for new functionality
+- Keep commits focused and atomic

+## Telemetry
+
+BackAnt CLI includes **opt-in** anonymous telemetry to help us improve the tool. On first run, you'll be asked if you want to participate.
+
+### Quick Disable
+
+```bash
+# Environment variable (permanent)
+export DO_NOT_TRACK=1
+
+# Per-command flag
+ant --no-telemetry generate api my-project
+
+# View telemetry settings
+ant --privacy
+```
+
+We **never** collect file paths, project names, usernames, or any personally identifiable information. See [docs/telemetry.md](docs/telemetry.md) for full details.
