≈ “Common” is an estimate: at least 1 in 5 of the 308,232 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Security Planning Skill
This skill is focused on ensuring systems are resilient against attacks and inherently protect user data.
When to use this skill
- When performing Threat Modeling (STRIDE) for new features.
- When planning Authentication, Authorization, and Session Management.
- When adhering to compliance requirements (GDPR, HIPAA, SOC2).
Guidelines
- Principle of Least Privilege: Services and users should only have the bare minimum access permissions they need.
- Defense in Depth: Do not rely on a single defensive mechanism. Validate inputs at the client, the API edge, and the database boundary.
- Secret Management: Never hardcode secrets. Plan to use KMS, HashiCorp Vault, or environment-injected managed identities.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
