Codex SEO

A suite of 12+ professional-grade SEO analysis tools, running natively inside Codex.

Independent community project, not affiliated with or endorsed by OpenAI.
Original project and concept: AgriciDaniel/claude-seo

Project Intent

codex-seo is designed as a port, not a reinvention.

Porting principles:

• keep Claude SEO structure, logic, and behavior as close as possible
• only add Codex-specific adaptations where platform differences require it
• avoid custom feature drift that changes core audit behavior

What Is Included

Primary SEO skill coverage (matches Claude SEO scope):

• seo-audit
• seo-page
• seo-technical
• seo-content
• seo-schema
• seo-images
• seo-sitemap
• seo-geo
• seo-plan
• seo-programmatic
• seo-competitor-pages
• seo-hreflang

Meta orchestrator skill:

• seo (top-level routing/orchestration skill)

Audit specialist agents:

• seo-technical
• seo-content
• seo-schema
• seo-sitemap
• seo-performance
• seo-visual

Codex-Specific Adaptation

The only intentional behavioral adaptation for audits is execution mapping:

• Claude subagent delegation maps to Codex multi-agent delegation (spawn_agent + wait)
• In Codex chat, /seo audit should default to this multi-agent path.

Everything else should remain aligned with upstream Claude SEO skill intent and output structure.

Codex Multi-Agent Requirement (Important)

For authentic /seo audit behavior in Codex chat, enable Codex experimental multi-agent mode:

1. Run /experimental in Codex.
2. Turn Multi-agent ON.
3. Start a new audit request.

Without this toggle enabled, Codex chat may fall back to non-parallel behavior and produce less complete delegation patterns.

Installation

One-command install (Unix/macOS/Linux)

curl -fsSL https://raw.githubusercontent.com/avalonreset/codex-seo/main/install.sh | bash

One-command install (Windows PowerShell)

irm https://raw.githubusercontent.com/avalonreset/codex-seo/main/install.ps1 | iex

Manual install

git clone https://github.com/avalonreset/codex-seo.git
cd codex-seo
pip install -r requirements.txt

Copy skills to Codex:

export CODEX_HOME="${CODEX_HOME:-$HOME/.codex}"
mkdir -p "$CODEX_HOME/skills/seo"
cp -r seo/* "$CODEX_HOME/skills/seo/"
for d in skills/*; do
  name="$(basename "$d")"
  mkdir -p "$CODEX_HOME/skills/$name"
  cp -r "$d/"* "$CODEX_HOME/skills/$name/"
done
mkdir -p "$CODEX_HOME/agents"
cp -r agents/* "$CODEX_HOME/agents/"

Quick Start

Use normal Codex prompts, for example:

• "Run a full SEO audit for https://example.com"
• "Analyze this page deeply: https://example.com/about"
• "Validate hreflang for https://example.com"
• "Generate a sitemap from this URL list"

Expected audit behavior:

1. fetches core pages
2. delegates to specialist agents in parallel (when Codex multi-agent is enabled)
3. merges findings into FULL-AUDIT-REPORT.md and ACTION-PLAN.md
