Security
Harden agent-operator repos with security cases that check prompt-injection resistance, context boundaries, and doc precedence rules.
Overview
Security is an agent skill most often used in Ship (also Operate) that encodes AgentOps security cases verifying prompt-injection resistance and context boundaries in operator docs.
Install
npx skills add https://github.com/boshu2/agentops --skill securityWhat is this skill?
- JSON-defined security cases with attack_prompt, severity, and glob-scoped targets
- Prompt-injection case enforcing source-of-truth precedence when docs disagree
- Context-overexposure case requiring least-privilege loading and context as a security boundary
- Pattern groups (require_groups) validate operator contracts like AGENTS.md and docs/strategic-direction.md
- Severity fail markers for cases that must block unsafe agent behavior
Adoption & trust: 773 installs on skills.sh; 384 GitHub stars; 2/3 security scanners passed (skills.sh audits).
What problem does it solve?
Your agent repo trusts every markdown file equally and lacks testable rules when attackers or noisy docs try to override AGENTS.md precedence.
Who is it for?
Indie builders maintaining agent-first repos who want machine-checkable guardrails on AGENTS.md and strategic context docs.
Skip if: Teams needing only OWASP web app scanning or infrastructure CVE monitoring without agent operator contracts.
When should I use this skill?
Hardening agent-operator repos, defining security cases for doc precedence and context exposure, or aligning AgentOps audits with AGENTS.md.
What do I get? / Deliverables
You get structured security cases with fail severity and pattern checks you can run against key paths so operator contracts enforce boundaries before agents execute work.
- Security case definitions with attack prompts and pattern requirements
- Pass/fail expectations mapped to repo globs
Recommended Skills
Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
AgentOps security cases belong on the ship shelf because they gate how autonomous agents read and trust repo docs before production workflows. Subphase security matches automated fail-severity checks against AGENTS.md and strategic docs, not perf tuning or release tagging.
Where it fits
Run fail-severity cases against AGENTS.md before turning an agent loose on production deploy tasks.
Re-validate strategic-direction.md patterns after a doc refactor that might widen agent context.
Encode require_groups patterns while authoring a new operator contract for a monorepo skill stack.
How it compares
Policy-and-pattern security cases for agent repos, not a standalone secrets scanner or WAF product.
Common Questions / FAQ
Who is security for?
Solo and small teams shipping agent workflows who treat AGENTS.md and doc precedence as part of the security surface.
When should I use security?
In ship security before enabling autonomous agents, and in operate iterate when you change docs, add skills, or expand what context agents may load.
Is security safe to install?
Check Prism Security Audits and upstream repo trust; cases reference reading repo files and assume you review attack_prompt fixtures before running automation.
