Ben Buttigieg 8215f3308b docs(codebuddy): fix dead install links and CodeBuddy capitalization (#3172) (#3216)
* fix(codebuddy): repoint install_url to codebuddy.cn (#3172)

The codebuddy.ai domain no longer resolves; CodeBuddy consolidated onto
codebuddy.cn (Tencent). Update install_url and docs links to
https://www.codebuddy.cn/cli (verified live).

* docs: use canonical 'CodeBuddy' capitalization in installation prereqs

Address Copilot review: the link text read 'Codebuddy CLI' while the rest of
the docs and the integration metadata use 'CodeBuddy'.

# Installation Guide
## Prerequisites
- **Linux/macOS** (or Windows; PowerShell scripts now supported without WSL)
- AI coding agent: [Claude Code](https://www.anthropic.com/claude-code), [GitHub Copilot](https://code.visualstudio.com/), [CodeBuddy CLI](https://www.codebuddy.cn/docs/cli/installation), [Gemini CLI](https://github.com/google-gemini/gemini-cli), [Pi Coding Agent](https://pi.dev), or [Oh My Pi](https://www.npmjs.com/package/@oh-my-pi/pi-coding-agent)
- [uv](https://docs.astral.sh/uv/) for package management (recommended) or [pipx](https://pipx.pypa.io/) for persistent installation
- [Python 3.11+](https://www.python.org/downloads/)
- [Git](https://git-scm.com/downloads) _(optional — required only when the git extension is enabled)_
## Installation
> [!IMPORTANT]
> The only official, maintained packages for Spec Kit come from the [github/spec-kit](https://github.com/github/spec-kit) GitHub repository. Any packages with the same name available on PyPI (e.g. `specify-cli` on pypi.org) are **not** affiliated with this project and are not maintained by the Spec Kit maintainers. For normal installs, use the GitHub-based commands shown below. For offline or air-gapped environments, locally built wheels created from this repository are also valid.
### Persistent Installation (Recommended)
Install once and use everywhere. Replace `vX.Y.Z` with a tag from [Releases](https://github.com/github/spec-kit/releases):
> [!NOTE]
> The command below requires **[uv](https://docs.astral.sh/uv/)**. If you see `command not found: uv`, [install uv first](./install/uv.md).
```bash
uv tool install specify-cli --from git+https://github.com/github/spec-kit.git@vX.Y.Z
```
Then initialize a project:
```bash
specify init <PROJECT_NAME> --integration copilot
```
### One-time Usage
Run directly without installing — see the [One-time usage (uvx)](install/one-time.md) guide.
### Alternative Package Managers
- **pipx** — see the [pipx installation guide](install/pipx.md)
- **Enterprise / Air-Gapped** — see the [air-gapped installation guide](install/air-gapped.md)
### Specify Integration
Interactive terminals prompt you to choose a coding agent integration during initialization. Non-interactive sessions, such as CI or piped runs, default to GitHub Copilot unless you pass `--integration`.
You can proactively specify your coding agent integration during initialization:
```bash
specify init <project_name> --integration claude
specify init <project_name> --integration gemini
specify init <project_name> --integration copilot
specify init <project_name> --integration codebuddy
specify init <project_name> --integration pi
specify init <project_name> --integration omp
```
### Specify Script Type (Shell vs PowerShell)
All automation scripts now have both Bash (`.sh`) and PowerShell (`.ps1`) variants.
Auto behavior:
- Windows default: `ps`
- Other OS default: `sh`
- Interactive mode: you'll be prompted unless you pass `--script`
Force a specific script type:
```bash
specify init <project_name> --script sh
specify init <project_name> --script ps
```
### Ignore Agent Tools Check
If you prefer to get the templates without checking for the right tools:
```bash
specify init <project_name> --integration claude --ignore-agent-tools
```
## Verification
After installation, run the following command to confirm the correct version is installed:
```bash
specify version
```
This helps verify you are running the official Spec Kit build from GitHub, not an unrelated package with the same name.
**Stay current:** Run `specify self check` periodically to learn whether a newer release is available — it is read-only and never modifies your installation. When you are ready to upgrade, follow the [Upgrade Guide](./upgrade.md).
After initialization, you should see the following commands available in your coding agent:
- `/speckit.specify` - Create specifications
- `/speckit.plan` - Generate implementation plans
- `/speckit.tasks` - Break down into actionable tasks
- `/speckit.implement` - Execute implementation tasks
- `/speckit.analyze` - Validate cross-artifact consistency
- `/speckit.clarify` - Identify and resolve ambiguities
- `/speckit.checklist` - Generate quality checklists
- `/speckit.constitution` - Create or update project principles
- `/speckit.converge` - Assess codebase against artifacts and append remaining tasks
- `/speckit.taskstoissues` - Convert tasks to issues
Scripts are installed into a variant subdirectory matching the chosen script type:
- `.specify/scripts/bash/` — contains `.sh` scripts (default on Linux/macOS)
- `.specify/scripts/powershell/` — contains `.ps1` scripts (default on Windows)
## Troubleshooting
### Enterprise / Air-Gapped Installation
If your environment blocks access to PyPI or GitHub, see the [Enterprise / Air-Gapped Installation](install/air-gapped.md) guide for step-by-step instructions on creating portable wheel bundles.
### Git Credential Manager on Linux
If you're having issues with Git authentication on Linux, see the [Air-Gapped Installation guide](install/air-gapped.md#git-credential-manager-on-linux) for Git Credential Manager setup instructions.
