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

forge-website 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.

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

Forge playbook — Website / landing / frontend

Do not duplicate ECC skills — defer to: design-is (design audit), browser (screenshot loop). This file is orchestration only.

Hard rules

  • Mobile and desktop layout verified by screenshot before claiming done.
  • No placeholder/Lorem/test/mock content in anything headed for prod.
  • Forms validate input and hit a real endpoint; clear error + success states.
  • Any analytics/form keys live in env, never in the committed bundle.

Team (conditional by stack/level)

  • Lead: planner / architect.
  • Build review: react-reviewer or vue-reviewer (by stack).
  • Audits (parallel): a11y-architect, seo-specialist, performance-optimizer.
  • Copy/CTA: marketing-agent.

Skills / commands / MCP

design-is (pick a real style direction first — see ~/.claude/rules/ecc/web/design-quality.md), browser (mobile+desktop screenshots), /react-build + /react-review (or the Vue equivalents), /test-coverage. Canva MCP only if asset generation is explicitly requested. humanizer skill (.claude/skills/humanizer/SKILL.md) MAY run as an on-demand rewrite pass on client-facing marketing/landing copy — never on exact-command setup docs or forge-report output, and not always-on (34KB context cost). When a build uses GSAP/ScrollTrigger for scroll-driven or compositor-friendly motion (per ~/.claude/rules/ecc/web/performance.md), load the relevant gsap skill (.claude/skills/gsap/<skill-name>/SKILL.md) on demand for correct API usage — not always-on.

Fan-out & flow

L2 for a single page, L3 for a multi-page site. Serial: design direction (design-is) → build → audits → fixes → review gate. Parallel: a11y ∥ seo ∥ performance ∥ copy audits on the built artifact (independent).

Domain gates

Accessibility pass; SEO meta/OG + canonical; performance budget (see ~/.claude/rules/ecc/web/performance.md); responsive at ~360/768/1280; CTA clarity; no broken links.

Ship-readiness (unique)

Screenshots at mobile+desktop breakpoints; no test copy; all CTAs/links resolve; forms submit to a real endpoint with validation; favicon/meta/OG present; 404 route; secrets in env. The ship-readiness website checklist is advisory; optionally run codex-reviewer (Codex) on important code — not a blocker.

Changes

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.
