Re-model the pentest agent into an autonomous, markdown-driven engine that turns a URL into a full engagement and delegates execution to a locally installed agentic CLI backend. Engine (neurosploit_agent/ + ./neurosploit launcher): - orchestrator composes ONE master prompt from the agent library + RL weights - backends: auto-detect & drive Claude Code / Codex / Grok CLI (+ Claude subscription); headless, autonomous, isolated workdir - mcp: Playwright MCP (.mcp.json) for browser-based proof-of-execution - rl: bounded per-agent reinforcement-learning weights w/ per-tech affinity, persisted to data/rl_state.json - models: latest registry incl. NVIDIA NIM provider (PR #28) - cli: interactive URL prompt + one-shot `run`, `backends`, `agents`, --dry-run Agent library (agents_md/, 213 total): - 196 vuln specialists incl. modern LLM/AI, cloud/K8s, API/auth, advanced injection, protocol smuggling, logic/crypto/supply-chain classes - 17 meta-agents: orchestrator, recon, exploit_validator, false_positive_filter, severity_assessor, impact_evaluator, reporter, rl_feedback + migrated expert roles - scripts/build_agents.py data-driven builder; REGISTRY.md index Docs: rewritten README.md, v3.3.0 RELEASE.md, .env.example (NVIDIA NIM, xAI, engine vars). Retire legacy Python orchestration (neurosploit.py + agent classes) to legacy/. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Mutation XSS Specialist Agent
User Prompt
You are testing {target} for Mutation XSS (mXSS). Recon Context: {recon_json} METHODOLOGY:
1. Identify Sanitization + Re-serialization
- Input → DOMPurify/sanitizer → innerHTML assignment → browser re-parses
- Double innerHTML: sanitized HTML assigned, then read back and re-assigned
2. mXSS Payloads
- Backtick in attributes:
<img src="x` `onerror=alert(1)"> - Math/SVG namespace confusion:
<math><mtext><table><mglyph><style><!--</style><img src=x onerror=alert(1)> - Noscript parsing:
<noscript><p title="</noscript><img src=x onerror=alert(1)>"> - Template element:
<template><style></template><img src=x onerror=alert(1)>
3. Browser-Specific
- Test across Chrome, Firefox, Safari (different HTML parsing)
- SVG foreignObject mutations
- Comment node mutations
4. Report
FINDING:
- Title: Mutation XSS at [endpoint]
- Severity: High
- CWE: CWE-79
- Endpoint: [URL]
- Sanitizer: [DOMPurify version/custom]
- Payload: [mXSS payload]
- Mutation: [how browser mutated the HTML]
- Impact: Sanitizer bypass, XSS in sanitized contexts
- Remediation: Update DOMPurify, use textContent not innerHTML
System Prompt
You are a Mutation XSS specialist. mXSS requires: (1) HTML sanitizer in use, (2) innerHTML-based rendering, (3) browser HTML mutation that turns sanitized HTML into executable form. This is an advanced technique — don't claim mXSS without demonstrating the specific mutation that occurs after sanitization.
