aegis-audit — Skillopedia

Aegis Audit Behavioral security scanner for AI agent skills and MCP tools. Aegis is a defensive security auditing tool. It detects malicious patterns in other skills so users can avoid dangerous installs. This skill does not teach or enable attacks — it helps users vet skills before trusting them. The "SSL certificate" for AI agent skills — scan, certify, and govern before you trust.

You're thorough, friendly, and occasionally silly in a low-key way. You're here to help developers understand what their code can do and whether that's a problem. You're not theatrical or dramatic — just genuinely curious and useful.\n\n## Your Role (IMPORTANT)\n\nYou run **AFTER** the deterministic static analysis (AST + Semgrep) has already completed. You never replace it — you layer on top. The static analysis is the source of truth; you add context, interpret unresolved scopes, and optionally adjust the risk score. Your output is advisory, not authoritative.\n\n## Your Vibe\n\nYou're the person on the team who reads the CWE docs for fun and flags the sketchy `eval()` in the PR. You explain things clearly without being preachy. You get a little excited when you find something interesting, but you keep it chill. You're warm and approachable — developers should feel like they learned something from your report, not like they're being lectured. No catchphrases, no roleplay. Just helpful, nerdy, and occasionally dry-humor observations.\n\n## Your Investigation Toolkit\n\nFor every piece of code you analyze, you systematically apply these investigative techniques:\n\n### 1. The Intent Test\n*\"What does this code WANT to do?\"*\nRead the code like a story. What's the narrative? Is this a legitimate tool doing legitimate things, or is something pretending to be what it's not? Look for the gap between what the code *claims* to do (names, comments, docstrings) and what it *actually* does.\n\n### 2. The Necessity Test\n*\"Does this code NEED these capabilities?\"*\nA weather API skill shouldn't need `subprocess.run`. A markdown formatter shouldn't need `socket.connect`. When capabilities don't match the stated purpose, that's a red flag. Rate how surprising each capability is on a scale of \"totally expected\" to \"wait, why??\"\n\n### 3. The Scope Test\n*\"Is the scope appropriate, or is it greedy?\"*\nA file reader that opens `./data/config.json` is fine. A file reader that opens `os.path.join(user_input, filename)` with no validation is concerning. Check whether scope is narrow (specific files, specific URLs) or wide-open (wildcards, user-controlled paths).\n\n### 4. The Exfiltration Sweep\n*\"Could data flow OUT in ways it shouldn't?\"*\nFollow the data. If the code reads secrets/files/env vars AND has network access, that's a potential exfiltration channel. Map the data flow: where does sensitive data enter, and where could it exit?\n\n### 5. The Persistence Check\n*\"Does this code try to outlive its welcome?\"*\nLook for signals of persistence: writing to startup files, registering atexit handlers, modifying sys.path, installing packages, writing cron jobs, or creating background threads that survive the main function.\n\n### 6. The Evasion Detection\n*\"Is someone trying to be clever?\"*\nWatch for: base64/hex encoding followed by exec, variable aliasing to hide dangerous calls, dynamic attribute access on dangerous modules, try/except blocks that swallow security errors, comments that contradict the code, misleading function names.\n\n### 7. The Supply Chain Check\n*\"Am I looking at the real thing?\"*\nCheck for: files that shadow stdlib modules (os.py, sys.py), unusual import paths, dynamic imports from user-controlled paths, packages being installed at runtime.\n\n## What You Receive\n\nYou'll be given:\n1. Code snippets with the specific function calls that triggered our static analysis\n2. AST-detected capabilities and their resolved scopes\n3. Unresolved scope values (variables/expressions we couldn't statically resolve)\n\n## What You Deliver\n\nApply your investigation toolkit, then respond in JSON format:\n\n```json\n{\n \"detective_notes\": \"Your analysis. Walk through what you found, what's suspicious, what's fine. Be specific, cite lines. Helpful and readable — not corporate boilerplate, not over-the-top. 2-4 paragraphs.\",\n \"verdict\": \"CLEAN | SUSPICIOUS | DANGEROUS\",\n \"confidence\": \"HIGH | MEDIUM | LOW\",\n \"risk_adjustment\": \u003cinteger between -20 and +20>,\n \"highlights\": [\n {\n \"type\": \"praise | concern | red_flag\",\n \"detail\": \"Specific observation with file:line reference\"\n }\n ],\n \"unresolved_scope_opinions\": [\n {\n \"file\": \"filename.py\",\n \"line\": 12,\n \"llm_opinion\": \"What this variable likely resolves to\",\n \"suspicion_level\": \"none | low | medium | high\"\n }\n ]\n}\n```\n\n### Field Guide:\n- **detective_notes**: Your main report. Be thorough and helpful. This is what developers read.\n- **verdict**: Your overall call. CLEAN = looks legit. SUSPICIOUS = some things need human review. DANGEROUS = do not run this code.\n- **confidence**: How sure are you? LOW if the code is ambiguous, HIGH if the intent is clear.\n- **risk_adjustment**: -20 to +20. Compute using the DETERMINISTIC RULES below. Same evidence must always yield the same number.\n- **highlights**: Your key observations. Mix praise (good security practices!) with concerns.\n- **unresolved_scope_opinions**: Your best guess at what dynamic values resolve to. Advisory only — doesn't change the signed report.\n\n## Deterministic Scoring Rules (risk_adjustment)\n\nApply these rules in order. Same inputs MUST produce the same risk_adjustment. Sum the applicable points, then clamp to [-20, +20].\n\n**Start at 0.**\n\n**Add points (static analysis under-counted or missed risk):**\n- +5 for each unresolved scope with suspicion_level=\"high\" that could expand to sensitive paths (filesystem, network, subprocess)\n- +3 for each unresolved scope with suspicion_level=\"medium\" in a high-risk category (fs, network, subprocess, secret)\n- +5 if you identify a clear exfiltration path (secrets/credentials + network) that static analysis did not flag\n- +5 if you identify evasion (base64+exec, getattr on dangerous module, dynamic import from user input) not already in PROHIBITED\n- +3 if documentation claims capabilities that the code does not implement (supply chain / impersonation risk)\n\n**Subtract points (static analysis over-counted):**\n- -5 only if PROHIBITED/RESTRICTED findings are clearly in dead code (unreachable, in `if False:` blocks) or test-only\n- -3 only if findings are in commented-out code or string literals\n- Do NOT subtract for \"looks benign\" or \"probably fine\" — only for mechanically provable over-flagging\n\n**Tie-breaker:** When in doubt, risk_adjustment = 0. Do not guess.\n\n## Ground Rules\n\n1. You NEVER say code is safe just because it looks professional or well-commented. Social engineering uses good comments.\n2. You NEVER ignore a finding just because \"it's probably fine.\" If the static analysis flagged it, investigate it.\n3. You ALWAYS follow the data flow. Secrets in + network out = exfiltration until proven otherwise.\n4. You CAN be wrong, and you say so when you're unsure. Confidence: LOW is honest and respected.\n5. Your detective_notes should be clear and helpful. No corporate boilerplate. Straightforward and useful.\n6. The deterministic static analysis is the source of truth. Your opinion is advisory — valuable, but never overrides the signed payload.\n7. For risk_adjustment, apply the Deterministic Scoring Rules exactly. Same evidence = same score.

Commercial / Enterprise License\n\nFor organizations that cannot comply with AGPL-3.0 obligations — for example, companies that:\n\n- Want to embed Aegis in proprietary products or services\n- Need to use Aegis without disclosing their own source code\n- Want to run the Aegis MCP Proxy or Dashboard as an internal service without AGPL obligations\n- Require SLAs, priority support, or enterprise-specific features\n\nA **commercial enterprise license** is available that removes all AGPL-3.0 requirements.\n\n**What the enterprise license includes:**\n\n| Feature | AGPL-3.0 (Free) | Enterprise License |\n|---------|------------------|-------------------|\n| CLI Scanner (`aegis scan`) | Yes | Yes |\n| Lockfile Verification (`aegis verify`) | Yes | Yes |\n| MCP Proxy (Runtime Guard) | Yes (AGPL) | Yes (proprietary use OK) |\n| Enterprise Dashboard | Yes (AGPL) | Yes (proprietary use OK) |\n| Audit Log Export / SIEM Integration | Yes (AGPL) | Yes (proprietary use OK) |\n| Embed in proprietary products | No (must release source) | Yes |\n| Run as internal service without source disclosure | No | Yes |\n| Priority support & SLA | No | Yes |\n| Indemnification | No | Available |\n\n**Contact:** For enterprise licensing inquiries, please contact [[email protected]](mailto:[email protected]).\n\n## Contributing\n\nBy contributing to this project, you agree to the [Contributor License Agreement (CLA)](./CLA.md), which grants the project maintainers the right to distribute your contributions under both the AGPL-3.0 and the commercial enterprise license. This is necessary to maintain the dual-license model.\n\n## FAQ\n\n**Q: Can I use the free AGPL version for my company's internal tools?**\nA: Yes, but if you modify Aegis and deploy it as a network service accessible to your users (even internal users), you must make the complete source code of your modified version available under AGPL-3.0.\n\n**Q: Do I need the enterprise license just to run `aegis scan` in my CI pipeline?**\nA: No. Running the unmodified CLI scanner in CI is fine under AGPL-3.0. The enterprise license is primarily for organizations that want to embed Aegis into proprietary services, run a modified proxy, or need commercial terms.\n\n**Q: What if I use the AGPL version and later want to switch to enterprise?**\nA: Contact us. We offer seamless transitions from AGPL to enterprise licensing.\n\n**Q: Can cloud providers offer Aegis as a managed service under AGPL?**\nA: Technically yes, but they must release the complete source code of their service (including any modifications and integration code) under AGPL-3.0. Most providers prefer the enterprise license instead.\n","content_type":"text/markdown; charset=utf-8","language":"markdown","size":3404,"content_sha256":"5dbf9b0bcd658196fdaa26961b92efa2b781756260312aff176fc67e7fe1d466"},{"filename":"pyproject.toml","content":"[build-system]\nrequires = [\"hatchling\"]\nbuild-backend = \"hatchling.build\"\n\n[project]\nname = \"aegis-audit\"\nversion = \"0.1.3\"\ndescription = \"Behavioral security scanner for AI agent skills and MCP tools — scan, certify, and govern.\"\nreadme = \"README.md\"\nlicense = \"AGPL-3.0-or-later\"\nrequires-python = \">=3.11\"\nauthors = [\n {name = \"Aegis Project Contributors\"},\n]\nkeywords = [\n \"security\",\n \"mcp\",\n \"ai-agent\",\n \"static-analysis\",\n \"vulnerability-scanner\",\n \"lockfile\",\n \"openclaw\",\n]\nclassifiers = [\n \"Development Status :: 4 - Beta\",\n \"Environment :: Console\",\n \"Intended Audience :: Developers\",\n \"License :: OSI Approved :: GNU Affero General Public License v3 or later (AGPLv3+)\",\n \"Operating System :: OS Independent\",\n \"Programming Language :: Python :: 3\",\n \"Programming Language :: Python :: 3.11\",\n \"Programming Language :: Python :: 3.12\",\n \"Programming Language :: Python :: 3.13\",\n \"Topic :: Security\",\n \"Topic :: Software Development :: Quality Assurance\",\n \"Topic :: Software Development :: Testing\",\n \"Typing :: Typed\",\n]\ndependencies = [\n \"typer\",\n \"rich\",\n \"pydantic>=2.0\",\n \"cryptography\",\n \"httpx\",\n \"pyyaml\",\n \"mcp>=1.0.0\",\n]\n\n[project.optional-dependencies]\nllm = [\n \"google-genai\",\n \"anthropic\",\n \"openai\",\n]\ndev = [\n \"pytest\",\n \"vcrpy\",\n \"pytest-asyncio\",\n]\n\n[project.urls]\nHomepage = \"https://github.com/Aegis-Scan/aegis-scan\"\nDocumentation = \"https://github.com/Aegis-Scan/aegis-scan#readme\"\nRepository = \"https://github.com/Aegis-Scan/aegis-scan\"\nIssues = \"https://github.com/Aegis-Scan/aegis-scan/issues\"\n\n[project.scripts]\naegis = \"aegis.cli:app\"\n\n[tool.hatch.build.targets.wheel]\npackages = [\"aegis\"]\n\n[tool.hatch.build.targets.sdist]\ninclude = [\n \"aegis/\",\n \"README.md\",\n \"LICENSE\",\n \"SKILL.md\",\n \"pyproject.toml\",\n]\n\n[tool.pytest.ini_options]\ntestpaths = [\"tests\"]\n","content_type":"text/plain; charset=utf-8","language":"toml","size":1915,"content_sha256":"9c887547e531eca513e386ee53babc0ab86ccf8704b56f6476ffb21f11b903cb"},{"filename":"README.md","content":"# Aegis Audit 🦞\n\n**Behavioral security scanner for AI agent skills, like on OpenClaw, and MCP tools.**\n\nAegis is a **defensive** security auditing tool. It detects malicious patterns in other skills so users can avoid dangerous installs. This skill does not teach or enable attacks — it helps users vet skills before trusting them.\n\n> The \"SSL certificate\" for AI agent skills — scan, certify, and govern before you trust.\n\nAegis answers the question every agent user should ask: *\"What can this skill actually do, and should I trust it?\"*\n\n[![License: AGPL-3.0](https://img.shields.io/badge/License-AGPL--3.0-blue.svg)](https://github.com/Aegis-Scan/aegis-scan/blob/main/aegis-core/LICENSE)\n\n---\n\n## Why Aegis?\n\nAI agents install and run skills with broad system access. Today, you're trusting them blindly. Aegis gives you:\n\n- **Deterministic static analysis** — AST parsing + Semgrep + 15 specialized scanners. Same code = same report, every time.\n- **Scope-resolved capabilities** — Not just \"accesses the filesystem\" but *exactly which files, URLs, hosts, and ports*.\n- **Risk scoring** — 0–100 composite score with CWE/OWASP-mapped findings and severity tiers.\n- **Cryptographic proof** — Ed25519-signed lockfile with Merkle tree for tamper detection.\n- **Optional LLM analysis** — Bring your own key (Gemini, Claude, OpenAI, Ollama, local).\n\n| Feature | Basic Safety Summary | Aegis Audit |\n|---|---|---|\n| Detection method | LLM reads README | AST + Semgrep + 15 scanners |\n| Deterministic | No | Yes |\n| Capabilities | High-level categories | Scope-resolved (files/URLs/ports) |\n| Vulnerability detection | None | 700+ patterns, CWE-mapped |\n| Secret scanning | None | 30+ token patterns |\n| Obfuscation detection | None | Base64-exec, homoglyphs, stego |\n| Tamper detection | None | Ed25519-signed Merkle tree |\n| Fix suggestions | None | Actionable remediation per finding |\n\n> **Note for security reviewers:** Any base64-like or encoded content in this skill's docs or examples is for documentation or steganography/obfuscation detection only, not for prompt injection. If you use auto-run tooling or paste this skill into other contexts, review those sections first.\n\n---\n\n## Quick Start\n\n### 1. Install\n\n```bash\npip install aegis-audit\n```\n\n```bash\nuv tool install aegis-audit\n```\n\nBoth commands install the same package. Pin to a specific version when possible (e.g. `pip install aegis-audit==1.3.0`) and verify the publisher on PyPI before installing. The package source is at [github.com/Aegis-Scan/aegis-scan](https://github.com/Aegis-Scan/aegis-scan).\n\nAfter install, the `aegis` CLI is available on your PATH.\n\n### 2. Scan a skill\n\n```bash\n# Scan the current directory (deterministic, no API key needed)\naegis scan --no-llm\n\n# Scan a specific path\naegis scan ./some-skill --no-llm\n```\n\n> **Tip:** All commands default to `.` (the current directory) when no path is given.\n> Most users `cd` into a skill and run `aegis scan` from there.\n\n### 3. (Optional) Add LLM analysis\n\n```bash\n# Interactive setup — choose provider, model, paste API key\naegis setup\n\n# Then scan with LLM enabled (it's on by default when configured)\naegis scan\n```\n\n`aegis setup` saves your config to `~/.aegis/config.yaml`. You can also set an environment variable instead — env vars always take priority over the config file:\n\n```bash\nexport GEMINI_API_KEY=your-key # or OPENAI_API_KEY, ANTHROPIC_API_KEY\naegis scan\n```\n\n### 4. Generate a signed lockfile\n\n```bash\naegis lock\n```\n\nThis runs a full scan and generates `aegis.lock` — a cryptographically signed snapshot of the skill's security state. Commit it alongside the skill so consumers can verify nothing changed.\n\n### 5. Verify a lockfile\n\n```bash\naegis verify\n```\n\nChecks that the current code matches the signed `aegis.lock`. If any file was modified, the Merkle root won't match and verification fails.\n\n---\n\n## CLI Reference\n\n| Command | Description |\n|---------|-------------|\n| `aegis scan [path]` | Full security scan with risk scoring |\n| `aegis lock [path]` | Scan + generate signed `aegis.lock` |\n| `aegis verify [path]` | Verify lockfile against current code |\n| `aegis badge [path]` | Generate shields.io badge markdown |\n| `aegis setup` | Interactive LLM configuration wizard |\n| `aegis mcp-serve` | Start the MCP server (stdio transport) |\n| `aegis mcp-config` | Print MCP config JSON for Cursor / Claude Desktop |\n| `aegis version` | Show the Aegis version |\n\nAll commands that take `[path]` default to `.` (current directory). Common flags: `--no-llm` (skip LLM), `--json` (CI output), `-v` (verbose). Run `aegis scan --help` (or `aegis lock --help`, etc.) for full flags.\n\n---\n\n## LLM Setup\n\nAegis works fully offline with deterministic analysis. LLM analysis is **disabled by default** — it adds an AI second opinion on intent and risk but is never required.\n\n**Privacy notice:** When enabled, Aegis sends scanned code to the configured third-party LLM provider (Google, OpenAI, or Anthropic). No data is transmitted unless you explicitly configure an API key and run a scan without `--no-llm`. Do not enable LLM mode on repositories containing secrets or sensitive code unless you trust the provider.\n\n### Option A: Interactive setup (recommended)\n\n```bash\naegis setup\n```\n\nThis walks you through:\n1. **Choose a provider** — Gemini, Claude, OpenAI, or a local server (Ollama, LM Studio, llama.cpp, vLLM)\n2. **Pick a model** — curated list per provider, or enter a custom model ID\n3. **Paste your API key** — hidden input, tested before saving\n\nConfig is saved to `~/.aegis/config.yaml`. Run `aegis setup` again anytime to change it.\n\n### Option B: Environment variables\n\nSet one of these and Aegis picks it up automatically:\n\n| Variable | Provider |\n|---|---|\n| `GEMINI_API_KEY` | Google Gemini |\n| `OPENAI_API_KEY` | OpenAI |\n| `ANTHROPIC_API_KEY` | Anthropic Claude |\n\nFor local servers:\n\n| Variable | Description |\n|---|---|\n| `OLLAMA_HOST` | Ollama server URL (default: `http://localhost:11434`) |\n| `AEGIS_LOCAL_OPENAI_URL` | Any OpenAI-compatible server URL |\n| `AEGIS_LLM_PROVIDER` | Force a specific provider: `openai`, `gemini`, `claude`, `ollama`, `local_openai` |\n\n---\n\nWe've established personas for code repositories that run with our deterministic checks, no LLM is required. Get to know our code personas:\n\n## Vibe Check Personas\n\nAegis assigns each scanned skill a persona based on deterministic analysis. The Vibe Check shows one of these:\n\n**🔥 Cracked Dev** \n10x engineer energy. Clean code, smart patterns, minimal permissions. The kind of skill you'd want to maintain.\n\n**✅ LGTM** \nLooks good to me. Permissions match the intent, scopes are sane, nothing weird. Ship it.\n\n**🍌 Trust Me Bro** \nPolished on the outside, suspicious on the inside. Docs vs code mismatch or unusual permissions. Trust, but verify.\n\n**🤔 You Sure About That?** \nThe intern special. Messy code, missing pieces, docs that overpromise. No malicious intent, but it needs a real review.\n\n**💕 Co-Dependent Lover** \nTiny logic, huge dependency tree. Loves node_modules. Supply chain risk is real here.\n\n**👺 Permission Goblin** \nWants everything: filesystem, network, secrets, the kitchen sink. Over-scoped and worth a closer look.\n\n**🍝 Spaghetti Monster** \nUnreadable chaos. High complexity, hard to follow. Good luck auditing this.\n\n**🐍 The Snake** \nWarning: This code might look clean, but it isn't. Do not use this skill, it is malicious by design.\n\n---\n\n## Example Output\n\n**This is actual Aegis output from scanning a skill, this is with the llm set-up and the --verbose details.**\nThis is the actual OpenClaw skill that I used for this test: https://clawhub.ai/alirezarezvani/senior-data-scientist\n\n```\n╭─ Aegis Security Audit ──────────────────────────────────────╮\n│ AEGIS SECURITY AUDIT │\n│ Target: C:\\Users\\TEST │\n│ Files: 8 (3 Python, 1 config, 4 other) │\n│ Source: directory │\n│ Mode: AST + LLM (gemini) │\n╰─────────────────────────────────────────────────────────────╯\n╭─ Vibe Check ────────────────────────────────────────────────╮\n│ 🤔 You Sure About That? │\n│ The intern special.

Install it and your agent will automatically audit skills before enabling them.\n\nSee [SKILL.md](https://github.com/Aegis-Scan/aegis-scan/blob/main/SKILL.md) for the full skill specification.\n\n---\n\n## JSON Output for CI\n\n```bash\n# Full JSON report to stdout\naegis scan --json --no-llm\n\n# Pipe into jq to extract the risk score\naegis scan --json --no-llm | jq '.deterministic.risk_score_static'\n\n# Fail CI if risk > 50\naegis scan --json --no-llm | jq -e '.deterministic.risk_score_static \u003c= 50'\n```\n\nThe JSON report contains two payloads:\n\n- **Deterministic** — Merkle tree, capabilities, findings, risk score (reproducible, signed)\n- **Ephemeral** — LLM analysis, risk adjustment (non-deterministic, not signed)\n\n---\n\n## Architecture\n\n```\naegis scan ./skill\n │\n ├── coordinator.py → File discovery (git-aware / directory walk)\n ├── ast_parser.py → AST analysis + pessimistic scope extraction\n ├── secret_scanner.py → 30+ secret patterns\n ├── shell_analyzer.py → Dangerous shell patterns\n ├── js_analyzer.py → JS/TS vulnerability patterns\n ├── config_analyzer.py → YAML/JSON/TOML/INI risky settings\n ├── combo_analyzer.py → Multi-capability attack chains\n ├── taint_analyzer.py → Source→sink data flow tracking\n ├── binary_detector.py → External binary classification\n ├── social_eng_scanner → Social engineering detection\n ├── stego_scanner → Steganography + homoglyphs\n ├── hasher.py → Lazy Merkle tree\n ├── signer.py → Ed25519 signing\n ├── rule_engine.py → Policy evaluation\n └── reporter/ → JSON + Rich console output\n │\n ▼\n aegis_report.json + aegis.lock\n```\n\n---\n\n## For Skill Developers\n\nBuilding a skill? See the [Skill Developer Best Practices](https://github.com/Aegis-Scan/aegis-scan/blob/main/docs/SKILL_DEVELOPER_GUIDE.md) guide for how to make your skills auditable, trustworthy, and easy to verify.\n\nRun Aegis on your own skill before publishing:\n\n```bash\ncd ./my-skill\naegis scan --no-llm -v\n```\n\nFix PROHIBITED findings. Document RESTRICTED ones. Ship with an `aegis.lock`:\n\n```bash\naegis lock\n```\n\n---\n\n## Project Structure\n\n```\naegis-audit/\n├── aegis-core/ # Python package (pip install aegis-audit)\n│ ├── aegis/ # Source code\n│ │ ├── cli.py # CLI entry point\n│ │ ├── mcp_server.py # MCP server\n│ │ ├── scanner/ # All 15+ analyzers\n│ │ ├── crypto/ # Hasher + signer\n│ │ ├── models/ # Pydantic models\n│ │ ├── policy/ # Rule engine\n│ │ └── reporter/ # Output formatters\n│ ├── tests/ # Test suite\n│ ├── pyproject.toml # Package config\n│ └── README.md # Detailed CLI reference\n├── docs/ # Governance & operational docs\n│ ├── CHANGELOG.md\n│ ├── SKILL_DEVELOPER_GUIDE.md\n│ ├── INCIDENT_RESPONSE.md\n│ ├── BCP_DR.md\n│ ├── RISK_REGISTER.md\n│ └── VENDOR_RISK.md\n├── scripts/ # Batch scanning utilities\n├── .github/ # CI + issue templates\n├── SKILL.md # ClawHub skill specification\n├── LICENSE # AGPL-3.0\n└── LICENSING.md # Dual license details\n```\n\n---\n\n## License\n\nAegis is dual-licensed:\n\n- **Open Source:** [AGPL-3.0](https://github.com/Aegis-Scan/aegis-scan/blob/main/aegis-core/LICENSE) — free to use, modify, and distribute.
