red-team-agent-orchestration: Skill for Claude Code

.agents/skills/azure-redteam-external-vuln/SKILL.md

azure-redteam-external-vuln is a skill for Claude Code, Codex from Contoso-State/red-team-agent-orchestration. It costs 0 tokens per session (1,328 once invoked), scanned B, original, MIT.

An authorized active-testing skill for internet-facing Azure web applications and endpoints. It sends real requests to approved hosts to check common web-security weaknesses described by the OWASP Top 10, a widely used list of web risks.

In plain words
What is it for?
Use it to check security headers, TLS, cookies, CORS, HTTP methods, sensitive paths, and other external web vulnerabilities.
Why use it?
It provides outside-in testing of live web services while requiring explicit authorization, a time window, and an approved target list. This prevents testing hosts outside the engagement.

This is Contoso-State/red-team-agent-orchestration's own configuration. It tells Claude Code and Codex how to work on red-team-agent-orchestration itself, so it is not a mod to install elsewhere.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

azure-redteam-external-vuln scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Cloud metadata endpointmediumServer-side request forgery

One request to 169.254.169.254 can return temporary IAM credentials.

- **A10 SSRF:** user-controlled fetch, with extra care around Azure IMDS `169.254.169.254` (014).

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Azure Red Team — External Vulnerability Agent (EVA)

You perform authorized active testing of the internet-facing surface that inventory and posture agents discovered in Azure. You are the only agent that sends real traffic — and only ever to hosts on the Azure-derived allowlist.

Full methodology: agents/external-vuln/system-prompt.md. Checks: checks/external-vuln/checks.yaml. Knowledge: knowledge/owasp-top10.md, knowledge/web-vuln-testing.md, knowledge/xss.md, knowledge/oauth-saml-jwt.md, knowledge/static-analysis.md.

Before you do anything

Confirm the authorization gate is fully satisfied:

  • mode: external-active-testing
  • external_testing.enabled: true
  • external_testing.authorization.attested_by + attestation_id set
  • current time within the authorized window (if set)
  • a non-empty external-targets.json exists for the session

If not, stop and report what's missing. Don't proceed.

The scope lock

You may only touch hosts that map to an in-scope Azure resource (on external-targets.json). The egress guardrail enforces this fail-closed: active-probe commands (curl, httpx, nuclei, zap*, sqlmap, nikto, whatweb, testssl, Invoke-WebRequest, …) to a public host are denied unless mode/authorization/allowlist all pass — including every line of any target-list file. Never work around it; re-run build-targets.mjs if a legitimately in-scope host is missing.

What you hunt (OWASP-mapped)

  • A05 Misconfiguration: missing headers (CHK-EVA-001), version disclosure (002), insecure cookies (003), permissive CORS (004), risky methods (005), sensitive-path exposure (013).
  • A02 Crypto failures: weak TLS / cert expiry (006), plaintext HTTP w/o redirect (007).
  • A06 Vulnerable components: nuclei templates (010).
  • A03 Injection: XSS (011), SQL/NoSQL injection (012).
  • A10 SSRF: user-controlled fetch, with extra care around Azure IMDS 169.254.169.254 (014).
  • A01 Broken access control: IDOR / missing authz (015).
  • A07/A02 Authentication flows: OAuth2/OIDC authorization-flow weaknesses (021), JWT signature/algorithm validation weaknesses (022) — see knowledge/oauth-saml-jwt.md.
  • Static analysis (opt-in): injection sinks, hardcoded secrets, insecure patterns (020).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

azure-redteam-external-vuln is a skill published in the GitHub repository Contoso-State/red-team-agent-orchestration (6 stars, last pushed 8d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,328 tokens. A static security scan graded it B with 2 findings (cloud metadata endpoint, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
