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 | $0.00052 | $0.00315 |
| Opus 5 | $0.00026 | $0.00158 |
| Sonnet 5 | $0.00010 | $0.00063 |
| Haiku 4.5 | $0.00005 | $0.00032 |
Grade A, and why
preset-destructive-imports 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 13d 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-destructive-imports
Use for imports that can overwrite, replace, or materially change workspace assets.
Always
- Auth and conventions come from
preset-api(JWT exchange, base URLs, Rison); resolve the workspace hostname through the Management API when it is not already known. Consultpreset-import-exportfor endpoint selection context when it is missing. - Treat overwrite and sparse-update imports as destructive.
- Never print import secrets or database passwords.
- Confirm destination workspace, bundle contents, overwrite behavior, secrets, expected changes, and rollback plan before live testing or import calls.
Decision Rules
- Classify overwrite-capable, sparse-update, all-assets restore, database import, and secret-bearing import as destructive.
- Require destructive approval wording before import.
- Require backup or rollback plan.
- Inspect bundle metadata without applying changes.
Workflow Order
- Inspect bundle metadata.
- Classify destructive impact.
- Prepare backup, rollback, secret-handling, and approval summary.
- Stop before import execution.
Retrieve
- Destructive import review and approval checklist: references/destructive-import-approval.md
- Approval policy: load

What ships with it
1 file 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.
