Claude-OSINT is a library of structured skills that guide Claude through external reconnaissance, including methodology, attack-surface analysis, security checks, risk assessment, and related investigative techniques. It is intended for authorized red-team and bug-bounty engagements. The catalogue entries are the project's own Claude skills for these reconnaissance workflows.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00078 | $0.01385 |
| Opus 5 | $0.00039 | $0.00692 |
| Sonnet 5 | $0.00016 | $0.00277 |
| Haiku 4.5 | $0.00008 | $0.00138 |
Grade A, and why
run-claude-osint 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 11d 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 — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Run: claude-osint
claude-osint is not an app — it's a Claude skills package. Its product
is two SKILL.md files (skills/offensive-osint/, skills/osint-methodology/)
plus two runnable Python helpers under skills/offensive-osint/scripts/. There
is no GUI, server, or TUI. "Running it" means: the SKILL.md frontmatter parses
and is complete (that's what Claude loads), and the helper scripts work.
The driver is .claude/skills/run-claude-osint/smoke.sh — it does all of
that in one shot. All paths below are relative to the repo root.
Prerequisites
Python 3 with PyYAML (already present on this container). If import yaml fails:
pip install pyyaml # or: apt-get install -y python3-yaml
The helpers are stdlib-only otherwise. h1_reference.py needs outbound HTTPS to
hackerone.com. No build step, no npm install — nothing to compile.
Run (agent path) — the driver
From the repo root:
.claude/skills/run-claude-osint/smoke.sh # full smoke (exits 0 on pass)
.claude/skills/run-claude-osint/smoke.sh --no-net # skip the HackerOne live check
It runs six checks and prints a ==> PASS / ==> FAIL line (exit 0 / 1):
py_compileboth helpers.secret_scan.pydetects AWS key + JWT from stdin (the CI canaries).secret_scan.pyrecursively scansskills/and emits JSONL (~11 findings — example tokens in the SKILL.md docs).- Every
skills/*/SKILL.mdhas valid YAML frontmatter withname/description/version/triggersand ≥5 triggers. sync-skill-content.sh --checkexits 0.h1_reference.pyfetches one live disclosed report (non-fatal if offline).

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

run-claude-osint is a skill published in the GitHub repository elementalsouls/Claude-OSINT (2,585 stars, last pushed 11d ago), licensed MIT. It adds 78 tokens to every session and 1,385 once invoked, about $0.0004 per session on Opus 5. 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.
