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 | $0.00193 | $0.00193 |
| Opus 5.5 | $0.00077 | $0.00077 |
| Sonnet 5.5 | $0.00039 | $0.00039 |
| Haiku 4.5 | $0.00019 | $0.00019 |
Grade A, and why
content-sdk copilot-instructions.md 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 15d 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
GitHub Copilot — Sitecore Content SDK
For AI agent instructions, commands, and coding rules in this repository, use:
AGENTS.md(repo root) — Canonical source: project overview, quick commands, package structure, DO/DON'T, boundaries, git workflow. For scaffolded head apps undersamples/, use that app’sAGENTS.md..cursor/rules/— Detailed coding rules (code-style, safety, sitecore, testing, etc.). Security and secrets: seesafety.mdc.Skills.mdand.agents/skills/— Capability-level instructions (e.g. component registration, Sitecore client, editing) for tools that support the Agent Skills standard.
Do not edit dist/**, commit .env/.env.local, or change CI/config without explicit instruction.
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.

content-sdk copilot-instructions.md is an instructions file published in the GitHub repository Sitecore/content-sdk (37 stars, last pushed yesterday), licensed Apache-2.0. It adds 193 tokens to every session, about $0.0008 per session on Opus 5.5. A static security scan graded it A with 0 findings.
