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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.05482 |
| Opus 5 | $0.00000 | $0.02741 |
| Sonnet 5 | $0.00000 | $0.01096 |
| Haiku 4.5 | $0.00000 | $0.00548 |
Grade A, and why
offensive-osint-methodology scanned grade A with 0 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 8d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 433 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SKILL: OSINT Methodology
Metadata
- Skill Name: osint-methodology
- Folder: offensive-osint-methodology
- Source: https://github.com/SnailSploit/offensive-checklist/blob/main/osint-method.md
Description
Structured OSINT methodology framework: target definition, source selection, collection workflows, data correlation, timeline reconstruction, and reporting. Use to guide systematic OSINT campaigns or teach OSINT methodology.
Trigger Phrases
Use this skill when the conversation involves any of:
OSINT methodology, open source intelligence, target profiling, data correlation, OSINT workflow, intelligence collection, OSINT campaign, recon methodology
Instructions for Claude
When this skill is active:
- Load and apply the full methodology below as your operational checklist
- Follow steps in order unless the user specifies otherwise
- For each technique, consider applicability to the current target/context
- Track which checklist items have been completed
- Suggest next steps based on findings

- Use separate browser profiles or isolation tools (e.g., Firefox Multi‑Account Containers) for any sock‑puppet activity.
- Acquire disposable VoIP/SMS numbers (e.g., Burner, Silent Link) to satisfy platform verification without exposing real phone numbers.
- Audit every browser extension before installation; supply‑chain attacks on popular add‑ons have targeted investigators since 2024.
- Use dedicated browser profiles/containers per case and persona; avoid logging into personal accounts.
- Prefer hardware‑backed passkeys for critical accounts; store recovery codes offline.
- Maintain a minimal chain‑of‑custody: timestamp actions, hash key artifacts, and record tool versions per case.
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-osint-methodology is a skill published in the GitHub repository SnailSploit/Claude-Red (3,040 stars, last pushed 8d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 5,482 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
