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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00042 | $0.00201 |
| Opus 5 | $0.00021 | $0.00101 |
| Sonnet 5 | $0.00008 | $0.00040 |
| Haiku 4.5 | $0.00004 | $0.00020 |
Grade A, and why
structured-data-authoring 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 8d 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
Structured Data Authoring
Generate and validate JSON-LD / schema.org structured data that matches the page's visible content.
Steps
- Choose the applicable schema.org type(s) for the content (Article, Product, FAQ, etc.).
- Populate required properties, then recommended ones; use real values from the page.
- Emit valid JSON-LD.
- Validate against the schema (required-property and type checks).
- Confirm the markup matches the visible on-page content — no cloaking or spec-invented fields.
Acceptance
- The JSON is valid and uses the correct type with required properties present.
- Markup reflects visible content (no cloaking).
- No invalid or spammy schema.
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.

structured-data-authoring is a skill published in the GitHub repository mtarcure/claude-vibe-squad (109 stars, last pushed 3d ago), licensed MIT. It adds 42 tokens to every session and 201 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
