--- title: Best agent Skills for Antigravity IDE slug: best-skills-for-antigravity type: agent-guide agent: antigravity targetQuery: best antigravity skills canonical: https://top-agent-skills.com/guides/best-skills-for-antigravity published: 2026-08-19 updated: 2026-08-26 --- # Best agent Skills for Antigravity IDE Antigravity IDE is the one agent where the first question is not what to install but what you already have: it ships with the awesome-skills bundle pre-installed, so the useful move is adding the few high-value Skills the bundle does not cover — frontend-design for UI direction, firebase-hosting for deploys, and Composio for tool routing. 36 of 206 catalogued Skills are verified here, and audit beats accumulation on this surface. ## How Skills install on this agent ```bash antigravity-awesome-skills install --skill frontend-design ``` 1. Check what is already installed before adding anything — Antigravity ships with a large bundle, and duplicates cost frontmatter tokens at every session start. 2. Install additions with the bundle CLI, using the command shown on each Skill page. 3. Restart the session so new Skill metadata is read. 4. Trigger the Skill and verify the behaviour changed rather than assuming the install took. Because Antigravity pre-installs a large Skill set, the cost model inverts relative to other agents. Elsewhere you pay to add capability; here you already pay frontmatter tokens for Skills you may never trigger, and precision suffers when many descriptions compete for the same task. Pruning is a legitimate optimisation on this agent. ## The picks ### 1. frontend-design (Official) The highest-scoring Skill we catalogue and verified on Antigravity. Bundled Skill sets tend to be broad and shallow on visual judgement; this is the one that changes design output rather than adding another capability. - Reach for it when: UI work where the result should look intentional. - Entry: https://top-agent-skills.com/skill/frontend-design (https://top-agent-skills.com/skill/frontend-design.md) ### 2. antigravity-awesome-skills (Community) The bundle itself — MIT, 22K stars, verified on five agents. Listed here because knowing what is in it is the prerequisite for deciding what to add, and because you can install it deliberately on other agents too. - Reach for it when: Auditing what your Antigravity install already covers, or reproducing that coverage on another agent. - Entry: https://top-agent-skills.com/skill/antigravity-awesome-skills (https://top-agent-skills.com/skill/antigravity-awesome-skills.md) ### 3. firebase-hosting-basics (Verified) Google-published, one-step deploy to Firebase Hosting, and one of the highest-scoring Skills verified on Antigravity. Deploy paths are the gap bundles most often leave. - Reach for it when: Shipping an app that already uses Firebase services. - Entry: https://top-agent-skills.com/skill/firebase-hosting (https://top-agent-skills.com/skill/firebase-hosting.md) ### 4. composio (Verified) Apache-2.0 and verified on every agent target we list. Broad third-party reach from one install, which is exactly what a general-purpose bundle cannot provide. - Reach for it when: Reaching many SaaS tools without hand-building connectors. - Entry: https://top-agent-skills.com/skill/composio (https://top-agent-skills.com/skill/composio.md) ### 5. debug (Official) Anthropic-authored, verified on Antigravity, and it changes behaviour on the most expensive class of session: an unexplained failure met with speculative edits. - Reach for it when: Any bug you cannot explain on first read. - Entry: https://top-agent-skills.com/skill/debug (https://top-agent-skills.com/skill/debug.md) ### 6. architecture-adr (Official) Turns architectural decisions into written records instead of leaving them in a chat log. On an agent that makes generating code very cheap, writing down why is what stops the codebase becoming unexplainable. - Reach for it when: A decision with consequences someone will question in three months. - Entry: https://top-agent-skills.com/skill/architecture-adr (https://top-agent-skills.com/skill/architecture-adr.md) ## Limits The pre-installed bundle is a real convenience and a real cost: Skills you never trigger still consume frontmatter tokens at session start, and a crowded Skill set makes triggering less precise because many descriptions compete for the same task. 36 of 206 catalogued Skills are verified on Antigravity, and a substantial share of those are Anthropic pack Skills — so check each entry's agent badges rather than assuming a Skill that works in Claude Code works here. Audit what you have before installing more. ## Common questions **Do I need to install Skills in Antigravity at all?** Not to get started — it ships with a large bundle pre-installed. Installing is for the specific gaps the bundle leaves, which in practice are visual design judgement, deploy paths, and broad third-party integration. **Does a big pre-installed Skill set slow the agent down?** It costs tokens rather than speed: each Skill contributes roughly 100 tokens of frontmatter at session start whether it fires or not. The subtler cost is triggering precision — when many descriptions overlap, the wrong Skill fires more often. **Can I remove Skills that ship with Antigravity?** Yes, and on this agent it is a reasonable thing to do. Pruning Skills you never trigger reduces both the per-session token floor and the competition between overlapping descriptions. --- _Top Agent Skills.
