mukul975 8cae0648ec Add 55 new skills across 3 new domains + 6 undercovered areas (762 -> 817)
Demand-driven expansion targeting the fastest-growing 2025-2026 threat and
skills categories (ISC2/WEF/CrowdStrike/Mandiant signals):

- AI Security (NEW domain, 12 skills): LLM red-teaming with garak/PyRIT,
  prompt injection (direct/indirect/RAG), MCP tool-poisoning, agentic tool
  invocation, guardrails, model/data poisoning, system-prompt leakage,
  embedding/vector weaknesses, model extraction, continuous red-teaming
- Supply Chain Security (NEW domain, 5 skills): SBOMs, dependency confusion,
  malicious-npm triage, typosquatting, SLSA/Sigstore provenance
- Hardware & Firmware Security (NEW domain, 4 skills): CHIPSEC/UEFI audit,
  Secure Boot bypass, TPM measured-boot attestation, ESP bootkit hunting
- Identity (10): Entra ID/ROADtools, GraphRunner, AADInternals, ADCS/Certipy,
  shadow credentials, coercion, BloodHound CE, device-code phishing, SSO abuse
- Cloud-native (8): Stratus, Pacu, CloudFox, container escape, K8s RBAC,
  Falco, Trivy, kube-bench
- Offensive C2 (6): Sliver, Havoc, NetExec, DPAPI, NTLM relay ESC8, redirectors
- DFIR (6): Hayabusa, Chainsaw, KAPE, Velociraptor, EZ Tools, Plaso
- Backfill (4): OpenCTI, MISP, honeytokens, post-quantum crypto migration

Each skill follows the repo taxonomy (SKILL.md + references/{standards,api-reference}.md
+ scripts/agent.py + LICENSE), with researched real tool commands (no placeholders),
complete frontmatter, and ATT&CK/ATLAS + NIST CSF mappings. Updates README domain
table, skill count, and index.json.

Standards and References — Auditing MCP Servers for Tool Poisoning

MITRE ATLAS References

Technique ID Name Tactic Rationale
AML.T0010 ML Supply Chain Compromise Initial Access A poisoned third-party MCP server compromises the agent supply chain
AML.T0051.001 LLM Prompt Injection: Indirect Initial Access Poisoned tool descriptions are indirect injection into agent context
AML.T0053 LLM Plugin Compromise Execution MCP tools are the agent's plugins; poisoning compromises them
AML.T0057 LLM Data Leakage Exfiltration Poisoned tools commonly exfiltrate files/secrets

NIST AI RMF References

ID Name Rationale
MANAGE-2.2 Mechanisms are in place and applied to sustain the value of deployed AI systems Auditing third-party MCP tools manages/sustains safe agent operation

OWASP MCP Top 10 (2025)

ID Name Rationale
MCP03:2025 Tool Poisoning Primary risk this skill audits
MCP01:2025 Prompt Injection Poisoned descriptions inject the agent
