Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00058 | $0.01716 |
| Opus 5 | $0.00029 | $0.00858 |
| Sonnet 5 | $0.00012 | $0.00343 |
| Haiku 4.5 | $0.00006 | $0.00172 |
Grade A, and why
headless-cms-expert 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 7d 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.

Description
Expert guide for selecting, integrating, and optimizing Headless CMS platforms in modern web applications. Covers Sanity v3 (GROQ, Portable Text, Content Lake), Payload CMS 3.x (TypeScript-first, code-defined schemas), Strapi 5 (open-source, self-hosted), Contentful (enterprise, GraphQL), and Storyblok (visual editing). Includes content modeling, preview mode, webhook-based revalidation, and migration strategies.
Trigger Conditions

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.

headless-cms-expert is a skill published in the GitHub repository roedyrustam/vibes-plug (50 stars, last pushed 3d ago), licensed MIT. It adds 58 tokens to every session and 1,716 once invoked, about $0.0003 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 2026-09-03.
