+## Project Overview
+
+**Spec Kit** is an open-source toolkit by GitHub for **Spec-Driven Development (SDD)** — a methodology where specifications are created first and then drive implementation via AI coding agents. The project ships:
+
+- **Specify CLI** (`specify`): A Python CLI that bootstraps projects with templates, scripts, and AI agent integrations for the SDD workflow.
+- **Templates & Commands**: Markdown/TOML command templates for 18+ AI agents (Claude Code, Gemini, Copilot, Cursor, Windsurf, etc.).
+- **Extension System**: A modular plugin architecture for adding commands and functionality without bloating the core.
+- **Scripts**: Bash and PowerShell helpers for feature setup, prerequisite checks, and agent context updates.
+
+### Tech Stack
+
+- **Language**: Python 3.11+
+- **Package Manager**: [uv](https://docs.astral.sh/uv/) (with `hatchling` build backend)
+- **CLI Framework**: Typer + Rich (for terminal UI)
+- **HTTP Client**: httpx
+- **YAML/Config**: PyYAML, packaging
+- **Linting**: Ruff (Python), markdownlint-cli2 (Markdown)
+- **Testing**: pytest + pytest-cov
+
+### Architecture
+
+- `src/specify_cli/__init__.py` — Main CLI entry point (~2400 lines). Contains `AGENT_CONFIG` (the single source of truth for all agent metadata), `init` and `check` commands, and all project bootstrapping logic.
+- `src/specify_cli/extensions.py` — Extension system (manifest validation, registry, installation/removal, command registration).
+- `templates/` — Spec, plan, tasks, and command templates used during project initialization.
+- `scripts/bash/` and `scripts/powershell/` — Shell scripts for feature creation, prerequisites, and agent context updates.
+- `extensions/` — Extension documentation, catalogs, and the extension template.
+- `tests/` — pytest test suite.
+
+## Building and Running
+
+```bash
+# Install dependencies
+uv sync
+
+# Install test dependencies
+uv sync --extra test
+
+# Run the CLI
+uv run specify --help
+uv run specify init <project-name> --ai claude
+uv run specify check
+
+# Run tests
+uv run pytest
+
+# Run tests with coverage
+uv run pytest --cov=src
+
+# Lint Python
+uvx ruff check src/
+
+# Lint Markdown
+npx markdownlint-cli2 '**/*.md' '!extensions/**/*.md'
+
+# Build release packages locally (for testing template/command changes)
+./.github/workflows/scripts/create-release-packages.sh v1.0.0
+```
+
+## Development Conventions
+
+### General Rules (from AGENTS.md)
+
+- Any changes to `__init__.py` for the Specify CLI **require a version bump** in `pyproject.toml` and an entry in `CHANGELOG.md`.
+- When adding a new AI agent, the `AGENT_CONFIG` dictionary key **must** match the actual CLI executable name (e.g., `"cursor-agent"` not `"cursor"`). This eliminates special-case mappings.
+- New agents require updates across: `AGENT_CONFIG`, CLI help text, `README.md`, release scripts, and agent context update scripts (both bash and PowerShell).
+
+### Code Style
+
+- Python source follows Ruff defaults (no local ruff config — uses defaults).
+- Markdown follows markdownlint-cli2 rules configured in `.markdownlint-cli2.jsonc` (ATX headings, 2-space indent, line length unrestricted).
+- Use docstrings for modules, classes, and public functions.
+- Type hints are used throughout (`typing.Optional`, `typing.Dict`, etc.).
+
+### Testing
+
+- Tests live in `tests/` and follow `test_*.py` naming.
+- pytest is configured with `-v`, `--strict-markers`, `--tb=short`.
+- Tests run on Python 3.11, 3.12, and 3.13 in CI.
+- Use `tempfile.mkdtemp()` for test fixtures requiring filesystem isolation.
+- When adding features or fixing bugs, add or update corresponding tests.
+
+### CI Workflows
+
+- **`test.yml`**: Runs Ruff lint on `src/` and pytest across Python 3.11–3.13.
+- **`lint.yml`**: Runs markdownlint-cli2 on all Markdown files (excluding `extensions/`).
+- **`codeql.yml`**: CodeQL security analysis.
+- **`release.yml`**: Automated release pipeline.
