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 | $0.00051 | $0.00426 |
| Opus 5 | $0.00026 | $0.00213 |
| Sonnet 5 | $0.00010 | $0.00085 |
| Haiku 4.5 | $0.00005 | $0.00043 |
Grade A, and why
preset-snowflake-cortex 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.
What it actually says
preset-snowflake-cortex
Use as the Snowflake Cortex routing and safety boundary before Cortex Agent REST or SQL workflows. This is for API/operator workflows, not Preset chatbot runtime instructions.
Always
- Resolve Snowflake account URL, auth method, role, warehouse, database, and schema.
- Do not use Preset workspace hostnames for Snowflake Cortex APIs.
- Do not print PATs, private keys, OAuth tokens, signed JWTs, or session tokens.
- Verify Cortex Agent privileges before live calls.
- Treat Cortex Agent execution as high impact because it can call tools, use warehouses, and expose governed Snowflake data.
- Re-check Snowflake docs for implementation work because Cortex schemas are evolving.
Decision Rules
- Classify Cortex readiness checks as read-only.
- Use configured Snowflake account and auth context.
- Verify role, warehouse, database, schema, Cortex privileges, and cross-region setting.
- Redact Snowflake secrets.
Workflow Order
- Resolve account and auth context.
- Inspect role, warehouse, database, and schema.
- Check Cortex privileges and cross-region setting.
- Report readiness without mutation.

What ships with it
5 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.

preset-snowflake-cortex is a skill published in the GitHub repository preset-io/agent-skills (11 stars, last pushed today), licensed Apache-2.0. It adds 51 tokens to every session and 426 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 2026-08-30.
