Metallegbob Solana Vibes Kit Stronghold Of Security

1. Look for .claude/svk-meta.json in the current project. If it doesn't exist, skip this check entirely.
2. Read the svk_repo path and installed_version from the metadata file.
3. Run: git -C <svk_repo> fetch --tags --quiet 2>/dev/null
4. Run: git -C <svk_repo> tag --sort=-v:refname | head -1 to get the latest tag.
5. Compare the installed version against the latest tag (strip the leading v).
6. If they match, skip — the user is up to date.
7. If the latest tag is newer, show this message ONCE (never repeat in this session):

SVK Update Available: v{latest} is available (you're on v{installed}).

• Update now: I can pull and reinstall the changed skills in this session
• Update later: Start a new chat and run /SVK:update

8. If the git commands fail (offline, repo moved, etc.), skip silently. Never show errors from version checking.

Important: Do NOT block or delay the user's actual command. Perform this check, show the notification if needed, then proceed with the command they invoked.

Stronghold of Security

A comprehensive, multi-agent adversarial security audit pipeline for Solana/Anchor smart contracts.

"The best defense is a thorough offense."

Getting Started

Stronghold of Security runs as a multi-phase pipeline. Each phase is a separate command with its own fresh context window, ensuring maximum quality throughout the entire audit.

Quick Start

/SOS:scan

This begins the audit by analyzing your codebase and generating a hot-spots map. Follow the prompts — each phase tells you what was produced and what command to run next.

Commands

Typical Workflow

Run /clear between each phase to give the next phase a fresh context window. This is critical for quality — each phase produces large outputs that would otherwise consume context.

1. /SOS:scan — Analyze your codebase
2. /clear
3. /SOS:analyze — Deploy auditors
4. /clear
5. /SOS:strategize — Generate attack strategies
6. /clear
7. /SOS:investigate — Run investigations
8. /clear
9. /SOS:report — Generate final report
10. (Fix vulnerabilities)
11. /SOS:verify — Confirm fixes are effective

Check progress anytime with /SOS:status.

Audit Tiers

The tier is auto-detected based on codebase size and complexity. Override with:

/SOS:scan --tier deep

Focus Areas

The 8 parallel context auditors each analyze through one lens:

1. Access Control & Account Validation — Authority, signer checks, PDA derivation, type cosplay, ownership
2. Arithmetic Safety — Overflow, precision loss, rounding
3. State Machine & Error Handling — Transitions, race conditions, invariants, panic paths, error propagation
4. CPI & External Calls — Cross-program invocation, program validation, privilege propagation
5. Token & Economic — Token flows, economic invariants, MEV
6. Oracle & External Data — Price feeds, staleness, manipulation
7. Upgrade & Admin — Upgradeability, admin functions, timelocks
8. Timing & Ordering — Front-running, transaction ordering, atomicity

Plus a conditional Economic Model Analyzer for DeFi protocols.

Knowledge Base

128 exploit patterns across 17 files (~480KB), built from 200+ research searches across 10 waves:

Key Incidents Covered

Wormhole ($320M), Mango Markets ($114M), Cashio ($52M), Crema Finance ($8.7M), MarginFi ($160M), Solend ($1.26M), Step Finance ($30-40M), Candy Machine V2 CVE, Metaplex pNFT bypasses, pump.fun exploits, Agave validator crashes, Ed25519 offset bypass, and 100+ more.

Output Structure

All audit outputs go to .audit/:

.audit/
  INDEX.md              — Structured codebase index with focus relevance tags
  KB_MANIFEST.md        — Knowledge base loading manifest
  HOT_SPOTS.md          — Phase 0.5 static pre-scan results
  context/              — 8-9 deep context analyses
  ARCHITECTURE.md       — Unified architecture understanding
  STRATEGIES.md         — Generated attack hypotheses
  findings/             — Individual investigation results
  COVERAGE.md           — Coverage verification report
  FINAL_REPORT.md       — The complete audit report
  VERIFICATION_REPORT.md — Post-fix verification (after /verify)
  PROGRESS.md           — Human-readable progress tracking
  STATE.json            — Machine-readable audit state

Why Phase-Based?

Each phase runs as a separate command with a fresh context window. This is critical for quality:

• Phase 1 agents produce 300-500KB of analysis each (~3-5MB total)
• No single context window can hold all of that for synthesis
• Each phase reads only what it needs (e.g., Phase 2 reads ~88KB of condensed summaries, not ~3.7MB of full analysis)
• Investigators in Phase 4 can deep-dive into specific focus areas' full analysis when needed
• Result: Higher quality at every stage of the pipeline

Installation

Copy the skill and commands to your project:

# Option 1: Manual copy
cp -R stronghold-of-security/ your-project/.claude/skills/stronghold-of-security/
cp -R stronghold-of-security/commands/ your-project/.claude/commands/SOS/

# Option 2: Install script
./stronghold-of-security/install.sh your-project/

Both the skills/ and commands/ directories are required:

• skills/stronghold-of-security/ — Skill definition, agents, knowledge base, resources
• commands/SOS/ — Subcommand orchestration files

Requirements

• Claude Code CLI
• A Solana/Anchor codebase to audit
• Optional: semgrep for enhanced Phase 0.5 scanning

Non-Goals

This skill does NOT:

• Generate exploit code
• Automatically fix vulnerabilities
• Replace human auditor judgment
• Guarantee completeness

The output is a comprehensive starting point for security hardening, not a certification of security. Security is a continuous process, not a one-time event.
