## Install
### One-Line Install
```bash
curl -fsSL https://raw.githubusercontent.com/AgriciDaniel/codex-seo/v1.9.6-codex.5/install.sh | bash
```
Windows:
```powershell
irm https://raw.githubusercontent.com/AgriciDaniel/codex-seo/v1.9.6-codex.5/install.ps1 | iex
```
### Review Before Installing
```bash
git clone https://github.com/AgriciDaniel/codex-seo.git
cd codex-seo
bash install.sh
```
Windows:
```powershell
git clone https://github.com/AgriciDaniel/codex-seo.git
cd codex-seo
powershell -ExecutionPolicy Bypass -File .\install.ps1
```
The installer copies the skill suite into `~/.codex/skills/`, installs TOML agents into `~/.codex/agents/`, creates a Python virtualenv at `~/.codex/skills/seo/.venv/`, installs core runtime dependencies, attempts optional capability groups, and verifies the runtime.
### Installer Overrides
```bash
CODEX_HOME=~/.codex \
CODEX_SEO_REPO=https://github.com/AgriciDaniel/codex-seo \
CODEX_SEO_REF=v1.9.6-codex.5 \
bash install.sh
```
| Variable | Purpose |
|---|---|
| `CODEX_HOME` | Alternate Codex home. Defaults to `~/.codex`. |
| `CODEX_SEO_REPO` | Git URL, fork URL, or local repository path. |
| `CODEX_SEO_REF` | Branch, tag, or commit. Defaults to `v1.9.6-codex.5`. |
| `CODEX_SEO_SKIP_PLAYWRIGHT_BROWSER=1` | Skip Chromium install for visual/PDF workflows. |
| `CODEX_SEO_PLAYWRIGHT_WITH_DEPS=1` | Ask Playwright to install system dependencies where supported. |
## Quick Start
Restart Codex after installation. Then ask naturally; a `/seo` command is not required:
```text
Do a full SEO check on https://example.com following best practices.
```
```text
Review this page for schema, Core Web Vitals, image SEO, and AI search readiness.
```
```text
Create an SEO strategy and content roadmap for a local dental clinic.
```
Command-style prompts also work:
```text
/seo audit https://example.com
/seo technical https://example.com
/seo schema https://example.com
/seo dataforseo serp "best seo tools"
```
## Visual Overview
Codex SEO is designed as a Codex-first routing layer: the user can ask naturally, the orchestrator selects the right specialist workflow, and deterministic runners write repeatable artifacts instead of relying on invisible chat-only output.

### Deterministic Runners
- `scripts/run_skill_workflow.py` standardizes output for every user-invokable workflow.
- `scripts/run_api_smoke_suite.py` runs all supported workflows in one pass.
- Setup-required workflows return structured fallback results instead of pretending live data exists.
## Extensions
| Extension | Skill | Setup | Notes |
|---|---|---|---|
| DataForSEO | `seo-dataforseo`, `seo-maps`, `seo-ecommerce`, `seo-cluster` | `./extensions/dataforseo/install.sh` | Live SERP, keyword, backlinks, on-page, content, business data, AI visibility |
| Google APIs | `seo-google`, `seo-performance` | `python scripts/google_auth.py --setup` | PageSpeed, CrUX, GSC, URL Inspection, Indexing API, GA4 |
| Firecrawl | `seo-firecrawl` | `./extensions/firecrawl/install.sh` | JS-rendered crawl, scrape, site map |
| Banana / Gemini | `seo-image-gen` | `./extensions/banana/install.sh` | AI image generation through `nanobanana-mcp` |
Optional integrations enrich the same workflow surface. If credentials or MCP servers are missing, wrappers return `setup_required` or `mcp_configured` states with no fabricated live data.

Demo readiness:
```bash
python scripts/demo_readiness.py --target https://example.com --live-apis --workflows --json
```
One low-depth DataForSEO proof:
```bash
python scripts/demo_readiness.py --target https://example.com --live-apis --live-serp --serp-keyword "seo tools" --json
```
## Headless/API Usage
Run a single workflow:
```bash
python scripts/run_skill_workflow.py --skill seo-technical https://example.com --json
python scripts/run_skill_workflow.py --skill seo-google https://example.com --json
python scripts/run_skill_workflow.py --skill seo-dataforseo https://example.com --json
```
Run the full smoke suite:
```bash
python scripts/run_api_smoke_suite.py https://example.com --json
```
Verify environment:
```bash
python scripts/verify_environment.py --target https://example.com --json
```
Bootstrap a clean runtime:
```bash
python scripts/bootstrap_environment.py --venv .venv --json
```
Artifacts are written to `output/`. Shared project cache is written to `.seo-cache/`. Both are ignored by git.

## Architecture
The repository separates Codex-facing instructions, deterministic runtime code, optional provider setup, and validation contracts. That keeps the skill system usable in chat, installable as a suite, and testable from CI/API workflows.

Design principles:
- `skills/` is the source of truth.
- `skills/seo/SKILL.md` routes natural-language SEO requests.
- TOML agents are Codex-native and mirror specialist workflows.
- Runtime credentials stay in `~/.config/codex-seo/` or `~/.codex/settings.json`.
- Legacy `claude-seo` config/cache paths are read only as migration fallback.
More detail: [docs/ARCHITECTURE.md](docs/ARCHITECTURE.md).
## Verification
Local release gate:
```bash
python -m pytest tests/
bash -n install.sh uninstall.sh
python -m compileall -q scripts hooks
python scripts/run_api_smoke_suite.py https://example.com --json
```
PowerShell parse check:
```powershell
$files = Get-ChildItem -Recurse -Filter *.ps1
foreach ($f in $files) {
$tokens = $null
$errs = $null
[System.Management.Automation.Language.Parser]::ParseFile($f.FullName, [ref]$tokens, [ref]$errs) > $null
if ($errs.Count) { $errs; exit 1 }
}
```
Current GitHub CI runs:
- dependency install
- shell syntax checks
- Python compile checks
- `--help` checks for runner scripts
- `python -m pytest tests/`
- contract smoke checks for MCP-aware workflows
## Requirements
- Codex CLI with local skills support
- Python 3.10+
- Git
- Optional: Playwright Chromium for screenshots and PDF reports
- Optional: DataForSEO account for live SEO data
- Optional: Google API credentials for PageSpeed/CrUX/GSC/GA4
- Optional: Firecrawl API key for JS-rendered crawling
- Optional: Google AI API key for Gemini/nanobanana image generation
## Credentials And Cache
Codex SEO writes new local credentials and state to Codex-specific paths:
- `~/.codex/settings.json` for MCP server configuration
- `~/.config/codex-seo/` for API configs and cost ledgers
- `~/.cache/codex-seo/` for runtime caches
- `.seo-cache/` inside the active project for cross-skill summaries
Legacy `~/.config/claude-seo/` and `~/.cache/claude-seo/` paths are read only as migration fallback. Do not commit `.seo-cache/`, `output/`, `.mcp.json`, `.env`, OAuth tokens, service accounts, or provider keys.
## Security
- URL-aware scripts block private, loopback, reserved, multicast, unspecified, and metadata hosts.
- Credential setup writes outside tracked repo files.
- Sensitive local settings are expected to use `0600` file permissions.
- DataForSEO calls use cost guardrails through `scripts/dataforseo_costs.py`.
- Report vulnerabilities through [SECURITY.md](SECURITY.md).
## Uninstall
```bash
bash uninstall.sh
```
Windows:
```powershell
powershell -ExecutionPolicy Bypass -File .\uninstall.ps1
```
