AI agent skills are reusable instruction sets that extend your assistant with domain-specific expertise, loaded on demand so they don't bloat your context. This repository covers marketing and engineering skills authored by @samber.

[!IMPORTANT] Bootstrapped with Claude. Edited, tested, reviewed and reworked by a human.
No AI slop here. AI-made skills are useless.
Install with skills CLI (universal, works with any Agent Skills-compatible tool):
npx skills add https://github.com/samber/cc-skills --all
# or a single skill:
npx skills add https://github.com/samber/cc-skills --skill promql-cli
/plugin marketplace add samber/cc
/plugin install cc-skills@samber
Copy skills into the cross-client discovery directory:
git clone https://github.com/samber/cc-skills.git ~/.openclaw/skills/cc-skills
# or in workspace:
git clone https://github.com/samber/cc-skills.git ~/.openclaw/workspace/skills/cc-skills
gemini extensions install https://github.com/samber/cc-skills
Update with gemini extensions update cc-skills.
Copy skills into the cross-client discovery directory:
git clone https://github.com/samber/cc-skills.git ~/.cursor/skills/cc-skills
Cursor auto-discovers skills from .agents/skills/ and .cursor/skills/.
Copy skills into the cross-client discovery directory:
/plugin install https://github.com/samber/cc-skills
# or
git clone https://github.com/samber/cc-skills.git ~/.copilot/skills/cc-skills
Copilot auto-discovers skills from .copilot/skills/.
Copy skills into the cross-client discovery directory:
git clone https://github.com/samber/cc-skills.git ~/.agents/skills/cc-skills
OpenCode auto-discovers skills from .agents/skills/, .opencode/skills/, and .claude/skills/.
Install the plugin via the Codex CLI:
codex plugin add github:samber/cc-skills
Update with codex plugin update cc-skills. Falls back to a manual clone if the marketplace path is unavailable:
git clone https://github.com/samber/cc-skills.git ~/.agents/skills/cc-skills
Codex auto-discovers skills from ~/.agents/skills/ and .agents/skills/.
Clone and symlink into the cross-client discovery path:
git clone https://github.com/samber/cc-skills.git ~/.antigravity/skills/cc-skills
Update with cd ~/.antigravity/skills/cc-skills && git pull.
These skills are designed as atomic units, cross-referencing units. A skill may reference conventions defined in another. Installing only a subset will give you a partial and potentially inconsistent view of the guidelines. For best results, install all general-purpose skills together.
Each skill lives in skills/<name>/ with a SKILL.md entry point. The SKILL.md is kept small with internal references to advanced markdown files, so only the relevant content is loaded into context.
