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: 1 finding, up to medium
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 →
- medium Excessive Agency · line 56 Skill grants unrestricted tool access without appropriate constraints. An agent with unfettered tool access can perform arbitrary actions including file modification, network requests, and code execution.Fix: Restrict tool access to only the tools required for the skill's stated purpose. Use an explicit allowlist rather than granting blanket access.
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 | $0.00200 | $0.03660 |
| Opus 5.5 | $0.00080 | $0.01464 |
| Sonnet 5.5 | $0.00040 | $0.00732 |
| Haiku 4.5 | $0.00020 | $0.00366 |
Grade A, and why
offensive-reporting 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.
Unrestricted tool accesslowExcessive agency
A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.
`payload`, `RCE`, `XSS`, `LDAP`, `SMB`, `kerberos`, `injection`. Translate every one. ("An attacker could run arbitrary commands on the server" not "RCE via deserialization gadget chain.") Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 372 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Penetration Test Reporting — Professional Methodology
A great finding lost in a bad report is a wasted finding. Reports are the artifact the client pays for, the auditor reads, and the developer fixes from. Treat the report with the same rigor as the exploit.
Quick Workflow
- Capture evidence as you exploit — never reconstruct after the fact
- Draft each finding immediately while context is fresh; one finding = one numbered file
- Build the executive summary last, after all findings are scored
- Two-pass review: technical accuracy first, then read-as-CISO for narrative
- Hand off with a retest plan and a JSON/CSV index for the client's tracking system
Report Structure (Standard)
1. Executive Summary ← Last to write, first read
2. Engagement Overview
2.1 Scope
2.2 Methodology
2.3 Limitations / Assumptions
2.4 Timeline
2.5 Team
3. Risk Summary ← Heatmap, finding count by severity
4. Technical Findings ← One per finding, sorted by severity
5. Attack Narratives / Chains ← Critical chains called out separately
6. Strategic Recommendations ← Programmatic, not finding-by-finding
7. Appendices
A. Tools Used
B. Indicators of Compromise (for blue team)
C. Raw Evidence Pointers
D. Glossary
Executive Summary — The 90-Second Read
The executive summary is for the CISO, the GRC officer, and the board member. They read this and nothing else.
Structure (one page max):
- Engagement context — what was tested, when, by whom (1 sentence)
- Headline finding — the worst thing you found, in business terms (2–3 sentences)
- Risk verdict — overall posture in plain language (1 paragraph)
- Counts — number of findings by severity, in a small table
- Top 3 strategic recommendations — programmatic fixes, not "patch CVE-X"
Words to avoid in the executive summary:
payload, RCE, XSS, LDAP, SMB, kerberos, injection. Translate every one. ("An attacker could run arbitrary commands on the server" not "RCE via deserialization gadget chain.")
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-reporting is a skill published in the GitHub repository SnailSploit/Claude-Red (7,620 stars, last pushed 8d ago), licensed MIT. It adds 200 tokens to every session and 3,660 once invoked, about $0.0008 per session on Opus 5.5. A static security scan graded it A with 2 findings (unrestricted tool access, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
