The file
We split this skill into the rules it gives an agent
2 rules. About 0 are common, 2 are distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈2
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 11
Use this skill only with explicit written authorization for a named scope (systems, environments, and time window).
- Distinctive: line 29
Do not produce exploit payloads, malware, or attack procedures.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 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.

Blue Team Defense
Authorization
Use this skill only with explicit written authorization for a named scope (systems, environments, and time window). If authorization is missing, expired, or the request is for someone else's systems, stop.
This skill is defensive and owner-authorized. It does not authorize offensive cyber operations.
Do
- Tune detections for true positives; document exceptions
- Pair every new control with a test or canary
- Share hunt hypotheses with IR, not with the public internet
Do not
- Disable EDR or logging to 'reduce noise' without a ticket
- Copy attacker malware into production 'for training'
- Do not produce exploit payloads, malware, or attack procedures.
How to Use
Load this skill from /cc-security when the Task Card domain is security-blue-team.
Example prompts:
We missed a token-replay. Propose a detection plus a unit test for the API gateway.Harden CI: pin actions, require reviews on workflows that deploy.
Integration
- Workflow:
/cc-security(CCEP commandsecurity) - Existing OWASP application-security skill remains
security(not this id) - High-risk changes still require
security-reviewer
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
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.
