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

product-proof-stage 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 11d 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.

What it actually says

product-proof-stage

Entry point for the Tell-adapted product-proof workflow skill.

Full playbook: agent-skills/web-design/premium-content-custom-web/product-proof-stage/SKILL.md

Quick contract

  1. Mechanism before claims — product panel is the evidence
  2. States: input → process → draft → review → approve (human gate; never auto-apply)
  3. Declared features only; label Sample workflow when not live
  4. HTMX stage swaps for progressive panels; static first frame always complete
  5. Taste Controls + aesthetic lean codes; dogfood Tell detectors
  6. Prefer designFromFeatures — layout workflow-proof on saas-marketing

After generate

If Tell is available: capture the preview → diagnose → fix any generic tells before handoff.

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.
