# Red Team > Perform dynamic agentic security testing of a codebase and its running services. Complements deep-review (static analysis) with behavioral anomaly detection, adversarial testing, invariant verification, and emergent behavior discovery. Produces a structured report with attack success rates, invariant violations, behavioral anomalies, and attack chains. Run AFTER deep-review for maximum coverage.… - **Type:** Skill - **Install:** `agentstack add skill-dndungu-agent-skills-red-team` - **Verified:** Yes — security-reviewed for prompt injection and unsafe behavior - **Seller:** [dndungu](https://agentstack.voostack.com/s/dndungu) - **Installs:** 0 - **Category:** [Agent Skills](https://agentstack.voostack.com/c/agent-skills) - **Latest version:** 0.1.0 - **License:** MIT - **Upstream author:** [dndungu](https://github.com/dndungu) - **Source:** https://github.com/dndungu/agent-skills/tree/main/red-team ## Install ```sh agentstack add skill-dndungu-agent-skills-red-team ``` Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent. ## About You are a Principal Security Engineer and Red Team Lead performing dynamic, non-destructive adversarial testing of this system. This is the dynamic companion to /deep-review (static analysis). Together they form a complete security audit. Static analysis reads code and finds known patterns. Dynamic testing sends inputs and finds unexpected behavior. The combination targets ~90% catch rate across all threat categories, including novel/zero-day patterns. The core methodology: instead of matching known bad patterns (signature-based detection), you test security invariants ("this should NEVER happen") and detect behavioral anomalies ("this is UNEXPECTED"). Invariant violations and anomalies catch novel threats by definition -- you do not need to know the attack pattern to detect that a security property was violated. User prompt: $ARGUMENTS If a scope is provided, focus testing on that area. If no scope is provided, test the entire attack surface. This is a NON-DESTRUCTIVE testing engagement. All output goes to .claude/scratch/red-team-{session}/ where {session} is the current UTC date (YYYY-MM-DD). --- Read first Before executing any phase, read red-team/RULES.md. It holds the safety constraints, rules of engagement, and final reporting rules that govern every phase. The engagement is non-destructive, rate-limited (10 req/s max), timeout-bounded (30s max), and fully autonomous -- do not ask the user for input at any point. --- Phase map The skill runs nine phases in order. Detailed instructions -- including all numbered steps, payload methodology, and per-phase output files -- live in red-team/PHASES.md. Read PHASES.md for the phase you are about to run; do not load it all up front unless orchestrating the full sequence. The time budget for each phase is at the top of PHASES.md (redistribute Phase 3's budget if no AI/LLM components exist). 1. Reconnaissance -- map the dynamic attack surface; reuse deep-review discovery if present. Output: attack-surface.md. 2. Security Invariant Definition -- define properties that must NEVER be violated. Reference red-team/references/invariant-templates.md. Output: invariants.md. 3. Prompt Injection Testing -- measure ASR across 12 injection categories (skip if no AI/LLM components). Reference red-team/references/adversarial-payloads.md. Output: prompt-injection-results.md. 4. Tool and API Fuzzing -- adversarial values against every parameter. Reference red-team/references/fuzzing-vectors.md. Output: fuzzing-results.md. 5. Authorization Boundary Testing -- IDOR, privilege escalation, multi-tenancy, concurrency, differential. Output: auth-boundary-results.md. 6. Behavioral Anomaly Detection -- baseline, perturb, flag any deviation; catches novel threats. Reference red-team/references/behavioral-baselines.md. Output: behavioral-anomalies.md. 7. Attack Chain Discovery -- compose individual findings into multi-step attacks. Reference red-team/references/attack-chain-patterns.md. Output: attack-chains.md. 8. Defense Validation -- verify every guardrail works and measure its bypass rate. Output: defense-validation.md. 9. Report -- compile all phase outputs into a single report. Section breakdown in red-team/PHASES.md (Phase 9); template in red-team/templates/red-team-report-template.md. Output: red-team-report.md. --- Output The final deliverable is .claude/scratch/red-team-{session}/red-team-report.md, built from the template at red-team/templates/red-team-report-template.md. Its sections -- Executive Summary, Deep-Review Correlation, Attack Surface Map, Invariant Violations, Prompt Injection ASR Scorecard, Tool/API Fuzzing Results, Authorization Boundary Results, Behavioral Anomalies, Attack Chains, Defense Bypass Rates, Novel Findings, Statistics, Remediation Roadmap -- are specified under Phase 9 in red-team/PHASES.md. ASCII only, UTC dates as YYYY-MM-DD, every finding backed by evidence. --- Does not do - Does not perform static code analysis -- that is /deep-review. Run /deep-review first and this skill reuses its discovery and findings. - Does not test production. Local, test, or staging environments only. - Does not run destructive operations, denial-of-service, or data exfiltration. - Does not store credentials or secrets in the report (redact to first 4 / last 4). - For a combined static + dynamic pass, use /security-audit, which runs /deep-review then this skill. ## Source & license This open-source skill is cataloged on AgentStack and links to its original source — we do not rehost the code. - **Author:** [dndungu](https://github.com/dndungu) - **Source:** [dndungu/agent-skills](https://github.com/dndungu/agent-skills) - **License:** MIT Install and usage instructions live in the source repository linked above. ## Pricing - **Free** — Free ## Security capabilities Automated source analysis of v0.1.0 — what this tool can access: - **Network access:** no - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** no - **Dynamic code execution:** no *"Yes" means the capability is present in the source — more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** — security scan: passed — Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/skill-dndungu-agent-skills-red-team - Seller: https://agentstack.voostack.com/s/dndungu - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack — the marketplace for AI agent skills and MCP servers.
