Antigravity Plugin for Claude Code

A local NotebookLM, multi-agent deep research, and 21 more commands — for Claude Code, powered by Google Antigravity (agy / Gemini 3.x), the official CLI that replaces the now-deprecated gemini-cli. Read whole folders of documents, transcribe audio & video, and research the web with citations — locally, offloading the heavy reading to Gemini so it barely touches Claude's context.

Project page: traidagency.com/labs/antigravity — built by TRAID.

⚠️ Heads-up: gemini-cli shuts down on June 18, 2026

On May 19, 2026 Google announced at I/O that Antigravity CLI (agy) replaces Gemini CLI. After June 18, 2026 the old gemini-cli and Gemini Code Assist IDE extensions stop serving requests for AI Pro, Ultra, and free-tier users.[1] [2]

Google's stated reasoning: "Your workflows have simply outgrown those early days of 2025. You now require multiple agents communicating with each other to split up the work and solve complex problems." — Google Developers Blog

If you were using gemini-plugin-cc inside Claude Code, this plugin is your migration path. It targets agy directly. Enterprise users on Code Assist Standard/Enterprise licenses are not affected by the cutoff.

TL;DR — /agy:notebook <folder> | <objective> turns a folder of documents into a local NotebookLM: one objective-driven summary per document, a relevance INDEX.md, a cited RESUMEN_MAESTRO.md, a TIMELINE.md and an ENTIDADES.md — then /agy:notebook-ask answers questions over them with citations. /agy:deep-research <topic> runs multi-agent deep research: an evidence matrix + plan you approve, agy browsing each angle in parallel while Claude orchestrates adaptive rounds (--depth L<=2 / H<=4) plus a red-team pass, landing on a cited, applied recommendation. All the heavy reading and browsing runs in Gemini 3.x via agy, so it barely touches Claude's context. Plus audio & video transcription (/agy:transcribe, /agy:media), single-shot web research with citations, branded HTML reports, git-diff code review, doc-to-markdown, browser recording and more. No Node.js runtime. No MCP gymnastics. Twenty-two slash commands.

What is this?

A Claude Code plugin that lets you delegate work to Google Antigravity CLI (agy) without leaving Claude Code.

• Antigravity CLI (agy) is Google's official agentic command-line assistant — released at Google I/O 2026 as the successor to gemini-cli. Rewritten in Go for speed, with native web-search grounding built into Gemini 3.x and multi-provider model support (Gemini, Claude, GPT-OSS).
• Claude Code is Anthropic's CLI for AI-assisted software engineering.
• This plugin bridges the two: from inside Claude Code, you invoke /agy:notebook, /agy:deep-research, /agy:research, /agy:report, /agy:ask, /agy:review, /agy:rescue, /agy:record, /agy:scrape, /agy:doc-to-md, /agy:design-review, or /agy:setup and the request gets handed to agy --print via a thin Bash forwarder.

The killer use case is deep web research with citations — Claude reasons over your repo, agy reasons over the live web. Each tool does what it's best at.

🗒️ Flagship: a local NotebookLM — /agy:notebook

Point it at a folder of documents (PDFs with text, scanned PDFs, images, docx) and an objective. agy (Gemini 3.x, multimodal) reads every document — OCR'ing the scans — and writes:

• one objective-driven summary per document (NN-<slug>.resumen.md, with relevancia 0–100),
• INDEX.md — every document ranked by relevance to your objective,
• RESUMEN_MAESTRO.md — a synthesis that answers your objective, citing each source document,
• TIMELINE.md — a chronological table of dated events, and
• ENTIDADES.md — extracted people, amounts, references and organizations, each with its source.

Then ask follow-up questions over the corpus:

/agy:notebook  ./docs  | objective: key decisions, owners, amounts, deadlines
/agy:notebook-ask  ./docs  | who owns the budget and when is it due?
→ "Owned by J. Doe; due 2026-07-08." (cites REP-0042)

Why it's different from pasting docs into a chat:

• Cheap on Claude tokens — Claude orchestrates; agy does all the document reading. You only read the two small final files.
• Grounded + cited — answers come only from your documents, with the source named.
• Incremental — re-running only re-summarizes new/changed documents (cache keyed by the objective).
• Model-routed — fast Flash for the per-doc sweep, Pro for the synthesis (/agy:model).
• Local & private — your documents never leave your machine + your own Gemini account.

It scales to real corpora: a 184-page scanned file is auto-split into page chunks so a single huge scan doesn't time out. Built for reading research papers, RFPs, contract sets, meeting-note archives, a book's chapters.

🗄️ Knowledge base — /agy:notebook-query (the corpus as a queryable SQLite DB)

/agy:notebook doesn't just write prose — the same pass emits a structured NN-slug.facts.json per document, and a pure-Python loader compiles them into a queryable SQLite database notebook.db (documents · entities · events · relations · citations + FTS5). So Claude Code can do exact, grounded, cited work instead of re-reading summaries:

/agy:notebook-query  ./docs  | sum the amounts by category
/agy:notebook-query  ./docs  | which documents mention 'Acme Corp'
/agy:notebook-query  ./docs  | build a project timeline
/agy:notebook-query  ./docs  | SELECT * FROM v_montos        # raw SQL works too

• Deterministic money math — amounts are stored as integer cents; SUM then divide by 100 (no float drift), each row citing its source document.
• Source-grounded — every entity/amount/date/reference traces to a document + a verbatim quote; 0 rows → "does not appear in the corpus", never invented.
• No new deps — Python stdlib sqlite3 only; the DB is disposable/gitignored and rebuilds incrementally.
• Drives downstream work — feed DB totals straight into your own scripts or reports. The notebook-kb skill teaches Claude when/how to use it.

For grounded prose instead of structured rows, use /agy:notebook-ask.

📊 How the local RAG works (visual): docs/semantic-rag-explainer.html — what it is, how it saves tokens, keyword vs semantic (FTS5 + vectors fused with RRF).

🕸️ Want a graph instead of/alongside the RAG? /agy:graph <folder> builds a knowledge graph via Graphify: the code graph is extracted locally with tree-sitter — no LLM, no API key, zero tokens on anyone's budget (NetworkX + Leiden + graph.html), Gemini via agy names the communities in one call, and Claude reads the result to reason. First run auto-installs graphify. See integrations/graphify-agy/.

🎙️ Audio & video transcription — /agy:transcribe & /agy:media

Claude Code can't hear audio or watch video; Gemini (via agy) can. These two commands give Claude Code native audio & video understanding:

• /agy:transcribe <audio|video file | YouTube/URL> [focus] — a faithful transcript + a summary, with timestamps for video and URLs. Works on voice notes, meetings, calls, screencasts and public YouTube/remote URLs (no download needed). Saved to docs/agy/transcripts/.
• /agy:media <file|URL> | <question> — multimodal Q&A over an audio/video/image with time-referenced answers ("what was decided around 02:30?", "what's the tone of this voice note?"). Saved to docs/agy/media/.
• /agy:video <file|URL> [focus] — watch a video and get a structured visual breakdown: scene-by-scene segments with timestamps, on-screen text/OCR (slides, charts, UI), and key moments — for screencasts, tutorials, demos, inspections. Saved to docs/agy/video/.

/agy:transcribe  ./reunion.mp4  | acuerdos y responsables
/agy:media  https://youtu.be/...  | ¿qué objeciones plantea el cliente y en qué minuto?

Common audio (ogg/opus/mp3/wav/m4a/flac) and video (mp4/mov/webm/…) formats work. Keep single files roughly under ~30 minutes to stay within the timeout, or split long recordings with ffmpeg first.

When should I use this plugin?

If you are…	This plugin helps because…
A Claude Code user who needs fresh information from the web with verifiable URLs	/agy:research returns a structured markdown report with cited sources, written to a file you can edit, review, and commit.
Already using agy from the terminal but switching between two CLIs breaks your flow	You stay in Claude Code for code work. /agy:* handles everything that needs agy.
Evaluating a new library, framework, or service and need a Tech Radar–style report	/agy:research --intensity high pulls 15+ primary sources (papers, official docs, repos), triangulates them, and emits a comparative analysis with confidence levels.
Building a proposal, RFP response, or technical pitch	/agy:research --intensity medium produces an 8–12 source executive summary you can paste into a doc with citations intact.
Migrating from the old gemini-plugin-cc (built on the deprecated gemini-cli)	This plugin uses the new agy CLI and has no Node.js companion runtime — drop-in replacement for research workflows.
