In plain words
What is it for?
Use it to inspect a landing page's technical SEO, schema markup, crawler rules, and signals that support visibility in search and AI-generated answers.
Why use it?
It checks whether a finished page can be correctly understood and found by search crawlers and other automated systems without changing the page itself.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

landing-discoverability scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 298 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Running an lp-* agent on Codex. Codex has no parallel subagent tool, and this pipeline is sequential and gated anyway. Wherever this file says to spawn or run an agent inline, it means: read .codex/agents/<name>.md and follow its full body verbatim as that phase's operating instructions, one phase at a time.

Landing Page Discoverability (Phase 5, standalone)

Run only phase 5 of the LandingForge pipeline: take an already-built page — a local site/ build or a live URL — and produce the discoverability report seo-report.md, the SEO + GEO artifact lp-scorer reads for the 25% Discoverability axis. This is a thin standalone wrapper around the lp-discoverability agent, which delegates to claude-seo for all real SEO/GEO validation and scoring. It does not write strategy, copy, design, or build a page; it audits a built one for discoverability and emits the report.

LandingForge keeps no SEO/GEO knowledge base of its own. claude-seo (agricidaniel-claude-seo/claude-seo) is the single source of truth for passage citability, crawler-policy theory, schema property validation, entity/authority signals, and GEO scoring. This phase's job is to (a) point that engine at the built page, (b) check the landing-specific build-time knobs LandingForge owns (SoftwareApplication JSON-LD, citable-passage shape, AI-crawler access), and (c) record the provenance of how the axis was earned.

Path resolution. All references/… and .codex/agents/… paths below are relative to the plugin root ({{LANDINGFORGE_ROOT}}, the directory containing plugin.json), not to this skill's own folder. The knowledge base and the agent contracts live at the plugin root on purpose — they are the one shared brain every LandingForge skill and agent reads. If a bare path such as references/discoverability.md or .codex/agents/lp-discoverability.md does not resolve from the current directory, prefix it with {{LANDINGFORGE_ROOT}}/.

Same report as the full pipeline. The seo-report.md this skill emits is the exact artifact landing-build phase 5 produces. A report committed here is a valid drop-in for phase 8: hand the built page + this report to the lp-scorer (via landing-critique or the wired landing-build loop) and it scores the Discoverability axis (D1–D10) from it. One engine, two entry points.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
