## What is this?
`claude-osint` is a library of skills for the [Claude skills system](https://docs.claude.com/en/docs/claude-code/skills). Each skill is a structured `SKILL.md` file that primes Claude with expert-level methodology for one part of the offensive recon problem.
**The core pair — the recon backbone:**
- **`osint-methodology`** - *how to think.* Strategic + procedural. Asset-graph discipline, severity rubric, time budgeting, identity-fabric mapping, deliverable templates.
- **`offensive-osint`** - *what to reach for.* Tactical arsenal. Probe paths, regexes, payloads, scoring rules, curl one-liners, tool URLs.
**Six organization-grade depth skills — enterprise-scale attack-surface reasoning the core pair doesn't carry:**
- **`org-attack-surface`** - legal entity → owned footprint (GLEIF org-tree, org-first RIR "dark netblock" recall, ASN hyperscaler-scope guard). Discover-only.
- **`email-domain-security`** - composite spoofability verdict (envelope vs header-From; SPF `-all` alone ≠ spoof-proof) + SPF supply-chain analysis.
- **`exposure-risk-quantification`** - FAIR 0–100 + A–F risk score, $-denominated loss model, board one-pager, ownership/proof honesty caps.
- **`continuous-exposure-monitoring`** - re-scan/diff loop + CTI/ransomware chatter + finding-lifecycle FP discipline + durable alert outbox.
- **`cloud-saas-exposure`** - bucket ownership-gated severity + offline AWS account-ID decode + dependency-confusion confirmation + K8s/CI fingerprint.
- **`identity-provider-recon`** - tenant/federation mapping + pre-auth user-enumeration oracle + name×pattern login synthesis, with a hard enumeration boundary.
Drop them into your Claude environment and it behaves like a senior recon analyst: it knows the techniques, the tooling, the edge cases, and the escalation paths — and it stays in scope.
~10,000 lines of structured tradecraft · **56/56 PASS** on a 56-prompt self-evaluation (100%, zero fabrications) · ~85–90% practitioner coverage for the recon phase of authorized engagements.
