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
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 8 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00332 | $0.06015 |
| Opus 5.5 | $0.00133 | $0.02406 |
| Sonnet 5.5 | $0.00066 | $0.01203 |
| Haiku 4.5 | $0.00033 | $0.00602 |
Grade A, and why
offensive-tls-attacks scanned grade A 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 1mo 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.
Asks for rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
adb shell chmod 644 /system/etc/security/cacerts/9a5ba575.0 Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

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

TLS/SSL Attacks and Misconfiguration Exploitation
You are performing offensive TLS/SSL analysis against target infrastructure. This skill covers the full attack surface of transport layer security -- from protocol-level cryptographic weaknesses to implementation bugs, certificate validation failures, and deployment misconfigurations. You treat every TLS handshake as an opportunity for enumeration and every certificate chain as a trust boundary to probe.
Quick Workflow
- Enumerate the target's TLS configuration -- supported protocols, cipher suites, certificate chain, extensions.
- Identify deprecated protocols (SSLv2, SSLv3, TLS 1.0, TLS 1.1) and weak cipher suites (export, NULL, RC4, DES, 3DES).
- Check for known protocol vulnerabilities -- POODLE, DROWN, FREAK, BEAST, Heartbleed.
- Test compression oracle exposure -- CRIME at the TLS layer, BREACH at the HTTP layer.
- Validate certificate handling -- chain verification, hostname matching, pinning enforcement, revocation checking.
- Assess TLS 1.3 features -- 0-RTT replay, downgrade sentinel presence, supported groups.
- For mobile targets, bypass certificate pinning and intercept traffic.
- Document findings with protocol evidence and remediation priorities.
TLS Enumeration and Scanning
Begin every TLS engagement with comprehensive enumeration. Use testssl.sh as the primary tool -- it requires no dependencies beyond bash and OpenSSL and produces detailed output covering protocols, ciphers, vulnerabilities, and certificate details.

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-tls-attacks is a skill published in the GitHub repository SnailSploit/Claude-Red (7,620 stars, last pushed 8d ago), licensed MIT. It adds 332 tokens to every session and 6,015 once invoked, about $0.0013 per session on Opus 5.5. A static security scan graded it A with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
