General Questions

What are "skills" exactly?

Skills are specialized instruction files that teach AI assistants how to handle specific tasks. Think of them as expert knowledge modules that your AI can load on-demand. Simple analogy: Just like you might consult different experts (a lawyer, a doctor, a mechanic), these skills let your AI become an expert in different areas when you need them.

Do I need to install every skill?

No! When you clone the repository, all skills are available, but your AI only loads them when you explicitly invoke them with @skill-name. It's like having a library - all books are there, but you only read the ones you need. Pro Tip: Use Starter Packs to focus on the skills that match your role first.

If you want a narrower install surface for Claude Code or Codex, use the new plugin distributions documented in plugins.md instead of the full library install.

What is the difference between Bundles and Workflows?

• Bundles are curated recommendations grouped by role or domain.
• Workflows are ordered execution playbooks for concrete outcomes.

Use bundles when you are deciding which skills to include. Use workflows when you need step-by-step execution.

Start from:

• bundles.md
• workflows.md

What is the difference between skills and MCP tools?

• Skills are reusable SKILL.md playbooks that guide an AI assistant through a workflow.
• MCP tools are integrations or callable capabilities that let the assistant interact with external systems.

Use skills when you want better process, structure, and execution quality. Use MCP tools when you need access to APIs, services, databases, or other systems. Use both when you want reliable workflows plus external capabilities.

For the longer explanation, read skills-vs-mcp-tools.md.

Which AI tools work with these skills?

• ✅ Claude Code (Anthropic CLI)
• ✅ Gemini CLI (Google)
• ✅ Codex CLI (OpenAI)
• ✅ Cursor (AI IDE)
• ✅ Antigravity IDE
• ✅ OpenCode
• ✅ Kiro CLI (Amazon)
• ✅ Kiro IDE (Amazon)
• ✅ AdaL CLI
• ⚠️ GitHub Copilot (partial support via copy-paste)

Are these skills free to use?

Yes. Original code and tooling are licensed under MIT, and original documentation/non-code written content is licensed under CC BY 4.0.

• ✅ Free for personal use
• ✅ Free for commercial use
• ✅ You can modify them

See ../../LICENSE, ../../LICENSE-CONTENT, and ../sources/sources.md for attribution and third-party license details.

How do these skills avoid overflowing the model context?

Some host tools (for example custom agents built on Jetski/Cortex + Gemini) might be tempted to concatenate every SKILL.md file into a single system prompt.
This is not how this repository is designed to be used, and it will almost certainly overflow the model’s context window if you concatenate the whole repository into one prompt.

Instead, hosts should:

• use data/skills_index.json as a lightweight manifest for discovery; and
• load individual SKILL.md files only when a skill is invoked (e.g. via @skill-id in the conversation).

For a concrete example (including pseudo‑code) see:

• docs/integrations/jetski-cortex.md

Do skills work offline?

The skill files themselves are stored locally on your computer, but your AI assistant needs an internet connection to function.

Does the hosted web app write anything back to the repository?

No. The public site is a static GitHub Pages deploy.

• The maintainer Sync Skills flow is local-development only and is not a public production endpoint.
• Browser save/star interactions are intentionally local-first for now. Until the project has a real backend contract, treat them as browser-local state rather than shared repository writes.

---

Security & Trust

What do the Risk Labels mean?

We classify skills so you know what you're running. These values map directly to the risk: field in every SKILL.md frontmatter:

• 🔵 none: Pure reference or planning content — no shell commands, no mutations, no network access.
• ⚪ safe: Community skills that are non-destructive (read-only, planning, code review, analysis).
• 🔴 critical: Skills that modify files, drop data, use network scanners, or perform destructive actions. Use with caution.
• 🟣 offensive: Security-focused offensive techniques (pentesting, exploitation). Authorized use only — always confirm the target is in scope.
• ⬜ unknown: Legacy or unclassified content. Review the skill manually before use.

Can these skills hack my computer?

No. Skills are text files. However, they instruct the AI to run commands. If a skill says "delete all files", a compliant AI might try to do it. Always check the Risk label and review the code.

---

Installation & Setup

Where should I install the skills?

It depends on how you install:

• Using the installer CLI (npx antigravity-awesome-skills): The default install target is ~/.gemini/antigravity/skills/ for Antigravity's global library.
• Using a tool-specific flag: Use --claude, --cursor, --gemini, --codex, --kiro, or --antigravity to target the matching tool path automatically.
• Using a manual clone or custom workspace path: .agent/skills/ is still a good universal workspace convention for Antigravity/custom setups.

If you get a 404 from npm, use: npx github:sickn33/antigravity-awesome-skills

Using git clone:

git clone https://github.com/sickn33/antigravity-awesome-skills.git .agent/skills

The installer CLI is the recommended path for most users because it performs a lighter shallow clone of the current library. Manual git clone is still the right option when you want the full repository history or plan to contribute from the same checkout.

Tool-specific paths:

• Claude Code: .claude/skills/
• Gemini CLI: .gemini/skills/
• Codex CLI: .codex/skills/
• Cursor: .cursor/skills/ or project root

Claude Code plugin marketplace alternative:

/plugin marketplace add sickn33/antigravity-awesome-skills
/plugin install antigravity-awesome-skills

This repository now includes .claude-plugin/marketplace.json and .claude-plugin/plugin.json so Claude Code can install the same skill tree through the plugin marketplace.

Codex plugin alternative:

This repository also includes repo-local plugin metadata for Codex:

• .agents/plugins/marketplace.json
• plugins/antigravity-awesome-skills/.codex-plugin/plugin.json

That path exposes the new plugin-safe Codex root plugin plus generated bundle plugins. For the full explanation, read plugins.md.

Why do I not see Sync Skills on the hosted website?

Because the public site is a static GitHub Pages catalog, not a maintainer control surface.

Sync Skills is only meant for local maintainer/development runs behind the Vite dev server, and it stays hidden unless the local environment explicitly enables it.

What does Public catalog mode mean?

It means you are looking at the published static catalog build.

In that mode:

• catalog browsing and skill detail pages work normally
• dev-only /api/refresh-skills behavior is not available
• anything that would require a backend or mutable server state is intentionally disabled or reduced to local-only behavior

Are saves/stars global or just local?

Right now they are local to your browser.

The app may show optional read-only community counts when configured, but clicking save/star does not create a shared server-side vote. Until the project ships a real backend write contract with abuse controls, treat saves as a personal local bookmark signal.

What does plugin-safe mean?

Plugin-safe means the published Claude Code and Codex plugins only include the subset of skills that is ready for marketplace-style distribution.

Skills can stay repo-only for a while if they still need:

• portability cleanup
• explicit setup metadata
• additional hardening for plugin ecosystems

So it is normal for the full library to be larger than the plugin-safe plugin subset. The repository stays the complete source of truth; plugins publish the hardened subset.

Does this work with Windows?

Yes. Use the same standard install flow as other platforms:

npx antigravity-awesome-skills

If you have an older clone created around the removed symlink workaround, reinstall into a fresh directory or rerun npx antigravity-awesome-skills.

I hit a truncation or context crash loop on Windows. How do I recover?

If Antigravity or a Jetski/Cortex-based host keeps reopening into:

TrajectoryChatConverter: could not convert a single message before hitting truncation

use the dedicated Windows recovery guide:

• windows-truncation-recovery.md

It includes:

• the manual cleanup steps for broken Local Storage / Session Storage / IndexedDB state
• the default Antigravity Windows paths to back up first
• an optional batch script adapted from issue #274

I hit context overload on Linux or macOS. What should I do?

If Antigravity becomes unstable only when the full skills library is active, switch to the activation flow instead of exposing every skill at once:

• agent-overload-recovery.md

That guide shows how to run scripts/activate-skills.sh from a cloned copy of this repository so only the bundles or skill ids you need stay active in ~/.gemini/antigravity/skills.

Gemini CLI hangs after a few turns or says "This is taking a bit longer, we're still on it". What should I do?

Start with a quick isolation check:

1. Start a brand-new Gemini CLI conversation.
2. Try one prompt with no skills at all.
3. Try the same task again with only one small skill such as brainstorming.
4. Temporarily reduce your active skill set to 2-5 skills and retry.

How to interpret the result:

• If plain Gemini CLI hangs even without skills, the problem is likely on the Gemini CLI/runtime side rather than this repository.
• If plain Gemini works, but hangs only when skills are present or after several turns, the likely cause is conversation/context growth.

In that case:

• keep a much smaller active set
• start fresh conversations more often
• use the overload guide: agent-overload-recovery.md

How do I update skills?

Navigate to your skills directory and pull the latest changes:

cd .agent/skills
git pull origin main

Using Skills

💡 For a complete guide with examples, see usage.md

How do I invoke a skill?

Use the @ symbol followed by the skill name:

@brainstorming help me design a todo app

Can I invoke a whole bundle like @Essentials or /web-wizard?

No. Bundles are curated lists of skills, not standalone invokable mega-skills.

Use them in one of these two ways:

• pick individual skills from the bundle and invoke those directly
• install the dedicated Claude Code or Codex bundle plugin if you want a marketplace-scoped subset
• use the activation scripts if you want only that bundle's skills active in Antigravity

Examples:

./scripts/activate-skills.sh --clear Essentials
./scripts/activate-skills.sh --clear "Web Wizard"

Can I use multiple skills at once?

Yes! You can invoke multiple skills:

@brainstorming help me design this, then use @writing-plans to create a task list.

How do I know which skill to use?

1. Browse the catalog: Check the Skill Catalog.
2. Search: ls skills/ | grep "keyword"
3. Ask your AI: "What skills do you have for testing?"

Troubleshooting

My AI assistant doesn't recognize skills

Possible causes:

1. Wrong installation path: Check your tool's docs. Try .agent/skills/.
2. Restart Needed: Restart your AI/IDE after installing.
3. Typos: Did you type @brain-storming instead of @brainstorming?

A skill gives incorrect or outdated advice

Please Open an issue! Include:

• Which skill
• What went wrong
• What should happen instead

Contribution

I'm new to open source. Can I contribute?

Absolutely! We welcome beginners.

• Fix typos
• Add examples
• Improve docs Check out CONTRIBUTING.md for instructions.

My PR failed "Quality Bar" check. Why?

The repository enforces automated quality control. Your skill might be missing:

1. A valid description.
2. Clear usage guidance or examples.
3. The expected PR template checklist in the PR body.

Run npm run validate locally before you push, and make sure you opened the PR with the default template so the Quality Bar checklist is present.

My PR failed "security docs" check. What should I do?

Run the security docs gate locally and address the findings:

npm run security:docs

Common fixes:

• Replace risky examples like curl ... | bash, wget ... | sh, irm ... | iex with safer alternatives.
• Remove or redact token-like command-line examples.
• For intentional high-risk guidance, add explicit justification via:

<!-- security-allowlist: reason and scope -->

My PR triggered the skill-review automated check. What is it?

Since v8.0.0, GitHub automatically runs a skill-review workflow on any PR that adds or modifies a SKILL.md file. It reviews your skill against the quality bar and flags common issues — missing sections, weak triggers, or risky command patterns.

If it reports findings:

1. Open the Checks tab on your PR and read the skill-review job output.
2. Address any actionable findings (missing "When to Use", unclear triggers, blocked security patterns).
3. Push a new commit to the same branch — the check reruns automatically.

You do not need to close and reopen the PR. Informational or style-only findings do not block merging.

Do community PRs need generated files like CATALOG.md or skills_index.json?

No. Community PRs should stay source-only.

Do not include generated registry artifacts like:

• CATALOG.md
• skills_index.json
• data/*.json

Maintainers regenerate and canonicalize those files on main after merge. If you touch docs, workflows, or infra, run npm run validate:references and npm test locally instead.

Can I update an "Official" skill?

No. Official skills (in skills/official/) are mirrored from vendors. Open an issue instead.
