What is this?

claude-bughunter is a drop-in skill bundle for the Claude Code skills system. Install once and Claude Code stops being a chatbot and starts behaving like a senior bug-hunting researcher or red-team operator: it knows the techniques, the chain templates, the VRT mappings, the platform CVE chains, and the hygiene — and it stays in scope.

Four layers stack:

• Think — bb-methodology + redteam-mindset: the 5-phase non-linear workflow, critical-thinking framework, and red-team operator discipline.
• Hunt webapps — 58 hunt-* skills curated from 681 disclosed HackerOne reports: per-class detection patterns, payloads, bypass tables, and chain templates.
• Hit the perimeter — enterprise platform chains (M365/Entra, Okta, vCenter, SSL-VPN appliances, SharePoint, cloud IAM): current 2024–2026 CVE chains + post-credential escalation.
• Ship it — triage-validation + reporting + evidence-hygiene: the 7-Question Gate, VRT-aware severity, OOS rebuttals, PII redaction, and red-team deliverables.

All triggered automatically by topic — describe what you're testing in plain English and the relevant skill loads. No invocation by name.

Quickstart

Option A — install as a Claude Code plugin (recommended). From inside Claude Code:

/plugin marketplace add elementalsouls/Claude-BugHunter
/plugin install claude-bughunter@elementalsouls

All 83 skills + 15 commands load namespaced under claude-bughunter: and update when you bump the plugin version — no files copied into ~/.claude/.

Option B — copy install (no plugin system / pin to a clone):

git clone https://github.com/elementalsouls/Claude-BugHunter.git
cd Claude-BugHunter

# macOS / Linux
bash scripts/install.sh

# Windows (PowerShell)
pwsh ./scripts/install.ps1

Both copy the skills + commands into ~/.claude/ (macOS/Linux) or %USERPROFILE%\.claude\ (Windows) and wire the hunt engagement scaffolder.

What each install path gives you:

Path	83 skills + 15 slash commands	cbh CLI	hunt scaffolder
A — plugin	✅ namespaced under claude-bughunter:	➕ separate pipx install	❌ clone-only
B — copy install	✅ copied into ~/.claude/	✅ from the clone	✅ from the clone

The plugin is the fastest path to the skills + slash commands. The terminal-native cbh runner installs standalone — pipx install git+https://github.com/elementalsouls/Claude-BugHunter — so plugin users can add it without a full clone (see cbh CLI). The hunt engagement scaffolder ships with the clone (Option B).
