arwp-prepare-site

arwp-prepare-site is a skill for Claude Code, Codex from dkharlanau/agent-ready-web-profile. It costs 97 tokens per session (1,872 once invoked), scanned A, original, Apache-2.0.

A set of instructions for preparing an existing website to be easier for search systems and AI agents to understand. It inspects the repository and applies machine-readable information and other website improvements while preserving the site's identity.

In plain words
What is it for?
Use it to prepare or migrate a website repository, add structured information, improve agent readability, and make search-related improvements measurable.
Why use it?
It addresses technical obstacles that can make a site difficult to classify, discover, cite, or read, without claiming guaranteed rankings or recommendations.

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

arwp-prepare-site 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/inspect-repo.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ARWP Prepare Site

Use this skill to turn an existing website repository into a high-quality, evidence-backed ARWP implementation.

Outcome

Deliver a working repository change, not a checklist. Preserve the site's product identity and framework while improving discoverability, citation readiness, agent readability, machine classification, freshness and agent interoperability.

ARWP must never be presented as a guaranteed Google ranking or AI recommendation mechanism. The goal is to remove technical blockers, implement current platform guidance, expose useful machine-readable surfaces and make improvement measurable.

Fast start

Run the deterministic repository inspector before broad manual exploration when executable skill scripts are available:

node scripts/inspect-repo.mjs <target-repository>

The helper reads only repository signals plus package.json, uses no network, and does not read secrets. Use its framework/public-root/source-of-truth hints to decide where changes belong; do not treat the report as deployed-site evidence.

If the skill is installed but the ARWP CLI/templates are not present, read references/toolchain-bootstrap.md and use an isolated temporary ARWP checkout rather than improvising commands or templates.

Load references only when needed

  • Read references/stack-detection.md when the framework/deployment/public-root model is unclear.
  • Read references/file-matrix.md before creating new machine-readable/public files so you do not cargo-cult every ARWP surface into every site.
  • Read references/page-semantics.md when the site needs structured data, entity identity, authors, events, datasets, terms, canonical cleanup or localization.
  • Read references/toolchain-bootstrap.md when the ARWP CLI/templates are not already available in the target environment.
  • Load arwp-ai-search-content when the main work is article/docs/comparison/answer quality.
  • Load arwp-agent-discovery when the main work is protocol/agent discovery.
  • Load arwp-evidence-ci when the main work is CI, contracts, receipts or ongoing monitoring.

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.
