Designed from First Principles

The GEO Guide

We curated hundreds of SEO and GEO best practices from official documentations and tutorials and distilled the knowledge into this set of skills for overgrow. Each individual primary source is summarized by gpt-5.4 into a few concise bullet points. We then use opus-4.7 to group and cluster all summarized bullet points into a condensed markdown format ready for skill usage at knowledge/geo.md.

Query Fan-out

Web searches on ChatGPT, Gemini, and Claude all use query fan-out to discover releveant content pieces before answering the prompt. We curated a base set of searches covering both specific and broad search intents and capture hundreds of real query fan-out behavior. We distill the behavior into a set of rules for reverse engineering fan-out patterns in knowledge/query-fanout.md. Overgrow uses this knowledge to propose new landing, blog, and resources pages.

Installation

Claude Code (recommended)

/plugin marketplace add zhizdev/overgrow
/plugin install overgrow@overgrow

Commands appear as /overgrow:init, /overgrow:audit, etc. Update with /plugin update overgrow@overgrow, or enable auto-update in /plugin → Marketplaces.

Cursor

cp -r .cursor your-project/

Cursor skills require setup: switch to Nightly in Settings → Beta, then enable Agent Skills in Settings → Rules. Cursor skills docs

Gemini CLI

cp -r .gemini your-project/

Gemini CLI requires the preview channel: npm i -g @google/gemini-cli@preview, then /settings → enable Skills, then /skills list. Gemini CLI skills docs

Codex CLI

cp -r .codex/* ~/.codex/

Codex uses a different command prefix: $overgrow:init, $overgrow:audit, etc.

Supported tools

• Claude Code — primary, plugin-install
• Cursor — drop-in .cursor/
• Gemini CLI — drop-in .gemini/
• Codex CLI — drop-in .codex/

One source of truth in source/skills/. The build transforms it into each provider's expected layout, frontmatter shape, and placeholder conventions — authored once, shipped four ways.

Contributing and Local Workflow

Skills are authored in source/skills/<name>/SKILL.md. The four dotfolders at the repo root (.claude/, .cursor/, .gemini/, .codex/) are generated artifacts.

Workflow

bun install                         # once
# edit source/skills/<name>/SKILL.md or files under knowledge/
bun run rebuild                     # regenerates the 4 dotfolders
bun test                            # 103 tests, ~60ms
git add -A
git commit -m "..."

Architecture

• source/skills/<name>/SKILL.md — canonical source per skill
• source/skills/<name>/reference/ — per-skill reference docs (bundled per provider)
• knowledge/*.md — shared authoritative references (shipped with the plugin)
• scripts/build.js — orchestrator: reads source, swaps provider placeholders, filters frontmatter, copies refs, writes dist/ + syncs the 4 dotfolders
• scripts/lib/transformers/ — provider config table + generic factory
• .claude-plugin/plugin.json — Claude Code plugin manifest
• .claude-plugin/marketplace.json — catalog so /plugin marketplace add zhizdev/overgrow works
