Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/full-stack-skills/openspec-skills --skill openspec-install- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads openspec-install automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
OpenSpec Install Skill
Install the OpenSpec CLI so that openspec is available globally. This skill covers only installing the CLI; it does not run openspec init. For project initialization after install, use openspec-initial.
When to Use
- First-time OpenSpec setup ("install OpenSpec", "get started with OpenSpec").
- User reports "openspec: command not found".
- Upgrading to the latest version.
- CI or scripts that need the CLI pre-installed.
Prerequisites
- Node.js 20.19.0 or higher — Check with
node --version. If not installed, guide the user to install Node.js first (e.g. via nvm, fnm, or official installer).
Workflow
-
Check if already installed
- Run
openspec --version. If it succeeds, the CLI is already installed; suggest openspec-initial for project setup or upgrading vianpm install -g @fission-ai/openspec@latest.
- Run
-
Choose package manager and install
- npm (most common):
npm install -g @fission-ai/openspec@latest - pnpm:
pnpm add -g @fission-ai/openspec@latest - yarn:
yarn global add @fission-ai/openspec@latest - bun:
bun add -g @fission-ai/openspec@latest - nix (one-time, no install):
nix run github:Fission-AI/OpenSpec -- init - nix (persistent):
nix profile install github:Fission-AI/OpenSpec
- npm (most common):
-
Verify installation
- Run
openspec --versionto confirm.
- Run
-
Upgrade existing installation
- Same command as install — e.g.
npm install -g @fission-ai/openspec@latest.
- Same command as install — e.g.
Outputs
openspeccommand available globally in PATH.
Next Steps
- Use openspec-initial to run
openspec initin a project. - Or use openspec-onboard for a guided tutorial.
Different Environments
| Environment | Command |
|---|---|
| npm | npm install -g @fission-ai/openspec@latest |
| pnpm | pnpm add -g @fission-ai/openspec@latest |
| yarn | yarn global add @fission-ai/openspec@latest |
| bun | bun add -g @fission-ai/openspec@latest |
| nix (one-time) | nix run github:Fission-AI/OpenSpec -- init |
| nix (persistent) | nix profile install github:Fission-AI/OpenSpec |
| CI | npm install -g @fission-ai/openspec@latest in a cacheable step |
Troubleshooting
- Node.js version too old: OpenSpec requires Node.js 20.19.0+. Upgrade Node.js first.
- Permission errors (npm): Use
npm install -gwithout sudo if using nvm/fnm; otherwise consider using nvm. - Command not found after install: Ensure the global bin directory is in PATH (check
npm bin -g). - nix not available: Install nix or use npm/pnpm/yarn/bun instead.

google/agents-cli
This skill should be used when the user wants to "write agent code", "build an agent with ADK", "add a tool", "create a callback", "define an agent", "use state management" — in a project that needs ADK (Agent Development Kit) API patterns and code examples. It provides a quick reference for agent types, tool definitions, orchestration patterns, callbacks, state management, the graph Workflow API, and reference recipes to study. Do NOT use for scaffolding (use google-agents-cli-scaffold) or deployment (use google-agents-cli-deploy).
embedded-captions

Add captions or subtitles to an existing single-subject talking-head video without editing the footage. Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog. Route by visual identity, not by backend engine. The quiet anchor rail is the default; embed every word only when the user explicitly wants a fully cinematic treatment. The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.
