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.

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 | $0.00000 | $0.02231 |
| Opus 5 | $0.00000 | $0.01115 |
| Sonnet 5 | $0.00000 | $0.00446 |
| Haiku 4.5 | $0.00000 | $0.00223 |
Grade A, and why
cms-live-preview-visual-builder-support-assistant 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 3d 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

Live Preview and Visual Builder Support Assistant
Description
Diagnose and guide Contentstack Live Preview and Visual Builder implementations. Trace preview context, identify the broken contract, and recommend the smallest correct fix across CSR, SSR, SSG, middleware/BFF, and tagging flows.
When to Use
Use this skill when a user is implementing or debugging Contentstack Live Preview or Visual Builder, including blank preview panels, stale or published-only preview, lost preview context after navigation, shared SSR state, cache contamination, or edit-tag mapping failures. Use it for code review when repo access is available and for implementation guidance when it is not.
User Problem
Users need help finding why Live Preview is blank, stale, or disconnected; why draft content is not reaching the renderer; why preview context is lost across navigation; or why Visual Builder cannot map rendered elements back to fields. The skill should identify the broken contract and recommend the smallest correct fix or implementation path.
Success Criteria
- Classifies the symptom into the correct failure bucket
- Identifies the rendering strategy and preview path in use
- Asks only the minimum evidence-based follow-up questions
- Traces preview context through the full request/render flow
- Names the most likely broken contract before suggesting a fix
- Recommends the smallest correct repair and a short verification checklist
- Provides implementation guidance when code inspection is not available
Expected Inputs
- Framework and route affected
- Rendering strategy used on the route
- Redacted preview URL or screenshot
- Contentstack Live Preview init code
- Preview vs delivery fetch code
- One failing network request with hostname and cache headers
- Display Setup Status screenshot when available
- Visual Builder tagging code when relevant
- Middleware, BFF, or redirect/rewrite code when relevant
Expected Outputs
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.

cms-live-preview-visual-builder-support-assistant is a skill published in the GitHub repository contentstack/contentstack-agent-skills (5 stars, last pushed 17d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,231 tokens. 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 2026-08-31.
