feat(llm-security-copilot): port llm-security v5.1.0 to GitHub Copilot CLI

Full port of llm-security plugin for internal use on Windows with GitHub
Copilot CLI. Protocol translation layer (copilot-hook-runner.mjs)
normalizes Copilot camelCase I/O to Claude Code snake_case format — all
original hook scripts run unmodified.

- 8 hooks with protocol translation (stdin/stdout/exit code)
- 18 SKILL.md skills (Agent Skills Open Standard)
- 6 .agent.md agent definitions
- 20 scanners + 14 scanner lib modules (unchanged)
- 14 knowledge files (unchanged)
- 39 test files including copilot-port-verify.mjs (17 tests)
- Windows-ready: node:path, os.tmpdir(), process.execPath, no bash

+
+# Security Audit
+
+Full project audit combining deterministic scanning with threat analysis.
+
+## Step 1: Run Posture Scanner
+
+```bash
+node <plugin-root>/scanners/posture-scanner.mjs
+```
+
+Parse JSON: grade A-F, risk score, categories, findings, counts.
+
+## Step 2: Gather Context
+
+Glob for project structure: commands, agents, hooks, skills, MCP configs, CLAUDE.md, settings files. Record what exists.
+
+## Step 3: Skill/Command Analysis
+
+Read `<plugin-root>/knowledge/skill-threat-patterns.md` and `<plugin-root>/knowledge/secrets-patterns.md`.
+
+Scan all command, agent, hook, and skill files for the 7 threat categories (injection, exfiltration, privilege escalation, scope creep, hidden instructions, toolchain manipulation, persistence). Apply frontmatter analysis, content analysis, and cross-reference checks.
+
+## Step 4: MCP Analysis (if MCP configs found)
+
+Read `<plugin-root>/knowledge/mcp-threat-patterns.md`.
+
+Scan MCP server configs for: tool poisoning, hidden instructions, rug pull signals, supply chain risks, permission surface.
+
+## Step 5: Merge and Report
+
+Merge posture scanner findings with threat analysis findings. Recalculate:
+`risk_score = min(100, critical*25 + high*10 + medium*4 + low*1)`
+
+Output:
+1. **Risk Dashboard** — Grade, risk score, verdict, finding counts
+2. **Executive Summary** — Key risks, posture overview
+3. **10 Category Sections** — One per OWASP/posture category with PASS/PARTIAL/FAIL and findings
+4. **Summary Table** — All findings sorted by severity
+5. **Action Items** — Grouped by urgency: IMMEDIATE (critical), HIGH (high), MEDIUM (medium)
+
+If grade C or lower: suggest running `threat-model` for deeper analysis.

+```
+
+Report: Applied, Skipped, Failed counts.
+
+## Step 5: Semi-auto Remediation
+
+For findings classified as semi-auto (entropy strings, permission mismatches, typosquatted deps, ghost hooks, suspicious URLs, credential access, hidden MCP directives, homoglyphs):
+
+1. Read the referenced files and understand the surrounding context
+2. Propose specific, minimal changes grouped by fix type
+3. Present each proposal to the user for confirmation before applying
+4. Apply confirmed changes via Edit tool
+
+## Step 6: LLM Threat Scan
+
+Read `<plugin-root>/knowledge/skill-threat-patterns.md`. Scan modified files for remaining threats. Report manual findings that require human judgment.
+
+## Step 7: Validate and Report
+
+Re-scan to verify fixes didn't introduce new issues. If validation fails, offer to restore from backup:
+```bash
+node <plugin-root>/scanners/lib/fs-utils.mjs restore "<target>"
+```
+
+Final report: pre/post comparison, fix summaries, remaining manual findings, rollback instructions.

+- Settings files with `mcpServers` sections
+- Global MCP configuration files
+
+## Step 3: Analyze Each Server
+
+Read `<plugin-root>/knowledge/mcp-threat-patterns.md`.
+
+For each discovered MCP server, perform 5-phase analysis:
+1. **Tool Description Analysis** — Check for hidden instructions, excessive length (>500 chars), Unicode anomalies, dynamic description loading
+2. **Source Code Analysis** — Code execution (eval/exec), network calls, file system access, credential access, time-conditional behavior
+3. **Dependency Analysis** — Run `npm audit` or `pip audit` as appropriate. Check for typosquatting, suspicious packages
+4. **Configuration Analysis** — Permission surface, declared vs actual scope, auth configuration
+5. **Rug Pull Detection** — Dynamic tool metadata, config self-modification, remote flag control, self-update mechanisms
+
+Trust rating per server: Trusted / Cautious / Untrusted / Dangerous.

+
+If local: Read target files directly. Apply 7 threat categories:
+1. **Prompt Injection** — `ignore previous`, `forget your`, identity redefinition, spoofed system headers
+2. **Data Exfiltration** — curl/wget to external URLs, base64 pipe chains, credential read+send
+3. **Privilege Escalation** — unjustified Bash access, Write+Bash without rationale, chmod/sudo
+4. **Scope Creep** — credential file access, crypto wallet paths, SSH keys, browser stores
+5. **Hidden Instructions** — Unicode Tag steganography, zero-width chars, base64 payloads, HTML comments
+6. **Toolchain Manipulation** — registry redirection, post-install scripts, external requirements
+7. **Persistence** — cron jobs, LaunchAgents, systemd, shell profile modification, git hooks
+
+For each finding: severity (Critical/High/Medium/Low/Info), category, file, line, OWASP reference, evidence, remediation.
+
+## Step 4: MCP Security Analysis (if applicable)
+
+Read `<plugin-root>/knowledge/mcp-threat-patterns.md`. Analyze MCP configs for: tool poisoning, hidden instructions in descriptions, rug pull signals, supply chain risks, permission surface.
+
+## Step 5: Aggregate and Report
+
+Combine counts. `risk_score = min(100, critical*25 + high*10 + medium*4 + low*1)`.
+Verdict: critical>=1 OR score>=61 → BLOCK, high>=1 OR score>=21 → WARNING, else ALLOW.
+
+Output banner then all findings grouped by severity (critical→info).
+
+## Step 6: Deep Scan (only if --deep)
+
+If `run_deep_scan = true`:
+```bash
+node <plugin-root>/scanners/scan-orchestrator.mjs "<target>" --output-file "<tmp>"
+```
+Parse results, merge with LLM findings, show "Deep Scan Findings" section.
+
+## Step 7: Cleanup (only if remote)
+
+Run cleanup commands from Step 1.

+
+# LLM Security Plugin
+
+Security scanning, auditing, and threat modeling. Based on OWASP LLM Top 10 (2025), Agentic AI Top 10, Skills Top 10, MCP Top 10, and DeepMind Agent Traps.
+
+## Skills
+

+| `pre-deploy` | Pre-deployment security checklist | Before pushing to production |
+| `registry [scan\|search]` | Skill signature registry | Track scanned skills |
+
+## What's Protected (Hooks)
+
+This plugin includes automated security hooks that run on every operation:
+
+| Hook | Protects Against |
+|------|-----------------|
+| Secret detection | API keys, tokens, passwords in code |
+| Path guarding | Writes to .env, .ssh, credentials files |
+| Destructive command blocking | rm -rf, force push, pipe-to-shell |
+| Supply chain protection | Compromised packages, typosquats |
+| Prompt injection scanning | Injection attempts in user prompts |
+| MCP output verification | Data leakage in tool outputs |
+| Session monitoring | Lethal trifecta detection (untrusted input + sensitive data + exfil) |
+
+## Quick Start
+
+- **New to security?** Start with `posture` for a quick health check
+- **Evaluating a plugin?** Run `plugin-audit path/to/plugin`
+- **Full analysis?** Run `scan . --deep` to combine LLM + deterministic scanners
+- **Machine-wide overview?** Run `dashboard`

+# Supply Chain Check
+
+Re-audit installed dependencies from lockfiles.
+
+## Step 1: Run Scanner
+
+```bash
+node <plugin-root>/scanners/supply-chain-recheck-cli.mjs $ARGUMENTS
+```
+
+Target = `$ARGUMENTS` or current working directory. Checks: package-lock.json, yarn.lock, requirements.txt, Pipfile.lock against blocklists, OSV.dev batch API, and Levenshtein typosquat detection.
+
+## Step 2: Format Results
+
+Parse JSON output. Show:
+
+```
+# Supply Chain Check: [STATUS]
+
+Findings: XC XH XM XL | Lockfiles: N scanned
+
+[If osv_offline: "OSV.dev unreachable — blocklist and typosquat checks ran, CVE checks skipped"]
+
+## Findings
+
+[Table: severity, package, ecosystem, type (blocklist/CVE/typosquat), description]

+---
+
+# Threat Model
+
+Interactive STRIDE/MAESTRO threat modeling session. 15-30 minutes → complete threat model document.
+
+## Principles
+
+- Ask one question at a time
+- Not a rubber stamp — challenge assumptions
+- Cite OWASP IDs (LLM01-LLM10, ASI01-ASI10)
+- Distinguish theoretical threats from actively exploited ones
+- Advisory output only — no file modifications
+
+## Phase 1: Architecture Discovery
+
+Read knowledge files:
+- `<plugin-root>/knowledge/skill-threat-patterns.md`
+- `<plugin-root>/knowledge/mcp-threat-patterns.md`
+- `<plugin-root>/knowledge/mitigation-matrix.md`
+
+Ask the user these questions (one at a time):
+1. What type of system is this? (plugin, MCP server, standalone agent, API service)
+2. What tools/MCP servers does the agent have access to? (file system, network, databases, external APIs)
+3. What data does the system handle? (credentials, PII, source code, business data)
+4. Who are the users and what's the trust model? (single developer, team, external users)
+5. How is it deployed? (local CLI, VS Code extension, cloud agent, CI/CD)
+
+## Phase 2: Component Mapping
+
+Map identified components to MAESTRO 7-Layer Model:
+- L1 Foundation Models — Base LLM capabilities
+- L2 Data Operations — RAG, embeddings, knowledge bases
+- L3 Agent Frameworks — Orchestration, tool routing
+- L4 Tool Ecosystem — MCP servers, API integrations
+- L5 Deployment — Runtime environment, containers
+- L6 Interaction — User interfaces, chat, CLI
+- L7 Ecosystem — Plugin marketplace, supply chain
+
+Present the mapping for user confirmation.
+
+## Phase 3: Threat Identification
+
+Apply STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege) to each relevant MAESTRO layer.
+
+For each threat: state actor, method, asset at risk, impact, OWASP ID, whether it's known to be exploited in the wild.
+
+## Phase 4: Risk Assessment
+
+Rate each threat: Likelihood (1-5) x Impact (1-5) = Risk Score.
+- 20-25: Critical — Immediate action required
+- 12-19: High — Address within current sprint
+- 6-11: Medium — Plan remediation
+- 1-5: Low — Accept or monitor
+
+Present the risk matrix for user validation.
+
+## Phase 5: Mitigation Mapping
+
+Read `<plugin-root>/knowledge/mitigation-matrix.md`. For each threat, classify the control status:
+- Already mitigated (existing hooks, settings)
+- Can be mitigated (configuration change or code fix)
+- Partially mitigated
+- Accepted risk (documented rationale)
+- External dependency
+
+## Output: Threat Model Document
+
+Produce an 8-section document:
+1. System Description
+2. Architecture Overview
+3. MAESTRO Layer Mapping
+4. Threat Catalog (per layer, with STRIDE/OWASP/likelihood/impact/scenario/control/recommendation)
+5. Risk Matrix
+6. Mitigation Plan (Critical+High actions, Already Mitigated, Accepted Risks)
+7. Residual Risk Summary
+8. Assumptions and Limitations

+---
+
+# Security Watch
+
+Set up continuous monitoring that runs security diffs on an interval.
+
+## Step 1: Parse Arguments
+
+- Target path = first positional argument or current directory
+- `--interval <value>` — monitoring interval (default: 6h). Supports: 30m, 1h, 6h, 12h, 24h.
+
+## Step 2: Create Initial Baseline
+
+```bash
+node <plugin-root>/scanners/scan-orchestrator.mjs "<target>" --save-baseline
+```
+
+Display baseline summary: verdict, risk score, finding counts.
+
+## Step 3: Start Monitoring
+
+For continuous monitoring, use the watch-cron scanner:
+
+```bash
+node <plugin-root>/scanners/watch-cron.mjs [--config <plugin-root>/reports/watch/config.json]
+```
+
+Or set up a system cron job / scheduled task:
+- **Linux/macOS cron:** `0 */6 * * * node <plugin-root>/scanners/watch-cron.mjs`
+- **Windows Task Scheduler:** Create a task that runs the same command on your preferred interval
+
+## Step 4: Advisory
+
+- Results stored in `<plugin-root>/reports/watch/latest.json`
+- Use `security-diff` to manually compare against baseline at any time
+- Watch-cron overwrites latest.json on each run
