data-safety

data-safety is a cursor rule for Cursor from hlalljie/agent-workflow-presets. It costs 83 tokens per session, scanned A, original, MIT.

A rule that forbids changing real or production data without the user's explicit permission.

In plain words
What is it for?
Use it as a safety boundary before writing data, and require confirmation and read-only checks before any destructive operation.
Why use it?
It prevents accidental edits to database records, external service data, or other information that may be difficult to restore.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

data-safety 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 4d 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

Do not write code or run commands that modify real data without explicit permission. This includes database records, external service data, and any destructive operations.

Before anything destructive:

  1. Confirm with user which records are safe to affect
  2. Prefer read-only probes first to verify targeting
  3. Proceed only after explicit approval
Changes

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.
