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 | $0.00441 |
| Opus 5 | $0.00026 | $0.00220 |
| Sonnet 5 | $0.00010 | $0.00088 |
| Haiku 4.5 | $0.00005 | $0.00044 |
Grade A, and why
preset-cortex-agents 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 10d 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-cortex-agents
Use for Snowflake Cortex Agent object management and run workflows.
Always
- Account, auth, role, warehouse, database/schema, privilege, and safety context comes from
preset-snowflake-cortex; consult it when that context is missing. - Prefer read-only list/describe before mutations.
- Require confirmation of query, role, tools, budget, and output handling before any run.
- Require rollback planning before create, update, replace, or delete.
- Treat streamed events as sensitive; store redacted summaries unless raw output handling is approved.
- Do not rely on pre-2025 Cortex Agent schemas.
Decision Rules
- Distinguish list and describe from run, create, update, and drop operations.
- Require approval for data-returning agent runs and mutations.
- Preserve streaming output handling and redaction.
- Require AUTOCOMMIT for SQL DDL workflows.
Workflow Order
- Verify Snowflake Cortex account, auth, role, warehouse, database, schema, and privilege context.
- List or describe agents first.
- Prepare run or mutation approval summary with tools, query, budget, and output handling.
- Stop before run, create, update, replace, or drop until approved.

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.
