Sanity Copilot eve Template is a Slack-based assistant that lets team members query and edit Sanity content, inspect schemas, manage drafts and releases, and send long-form drafts to Notion. Teams use it to work on Sanity projects through Slack with each person's permissions and approval controls for sensitive actions. The catalogue add-ons support this agent workflow.
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 5.1 | $0.00076 | $0.00351 |
| Opus 5 | $0.00038 | $0.00176 |
| Sonnet 5 | $0.00015 | $0.00070 |
| Haiku 4.5 | $0.00008 | $0.00035 |
Grade A, and why
content-modeling-best-practices 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.
This is a copy
98% identical to content-modeling-best-practices — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Content Modeling Best Practices
Principles for designing structured content that's flexible, reusable, and maintainable. These concepts apply to any headless CMS but include Sanity-specific implementation notes.
When to Apply
Reference these guidelines when:
- Starting a new project and designing the content model
- Evaluating whether content should be structured or free-form
- Deciding between references and embedded content
- Planning for multi-channel content delivery
- Refactoring existing content structures
Core Principles
- Content is data, not pages — Structure content for meaning, not presentation
- Single source of truth — Avoid content duplication
- Future-proof — Design for channels that don't exist yet
- Editor-centric — Optimize for the people creating content
References
Start with the reference that matches the modeling decision in front of you, instead of loading every topic at once. See references/ for detailed guidance on specific topics:
references/separation-of-concerns.md— Separating content from presentationreferences/reference-vs-embedding.md— When to use references vs embedded objectsreferences/content-reuse.md— Content reuse patterns and the reuse spectrumreferences/taxonomy-classification.md— Flat, hierarchical, and faceted classification
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
