oban — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited oban (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Quick reference for Elixir Oban patterns.
Before applying patterns, check for Oban Pro:
grep -E "oban_pro|oban_web" mix.exs
grep -r "use Oban.Pro.Worker" lib/
grep -r "Oban.Pro.Engines.Smart" config/If Oban Pro detected, use Pro patterns for ALL new workers:
| Standard Oban | Oban Pro |
|---|---|
use Oban.Worker | use Oban.Pro.Worker |
def perform(%Job{}) | def process(%Job{}) |
Oban.Testing | Oban.Pro.Testing |
| Advisory lock engine | Oban.Pro.Engines.Smart |
Pro features (all optional): args_schema (typed args), Workflows, Batches, Chunks, Relay, hooks, encryption, deadlines, chaining, Smart Engine (global concurrency + rate limiting). Pro plugins (DynamicCron, DynamicLifeline, DynamicPruner) enhance OSS equivalents — swap module, don't run both. See ${CLAUDE_SKILL_DIR}/references/oban-pro-basics.md for all patterns and migration guide.
