Stack traces not always surfaced + +4. **Validation** + - No CI/CD pipeline visible (only `release.yml`) + - No linting configuration (though Ruff is configured) + - No pre-commit hooks + +5. **Scalability** + - Registry only stores "latest" version (single row per package) + - No version resolution or dependency management + - Limited to simple tarball distribution + +--- + +## Security Analysis + +### Threat Model + +**Protected Against:** +- ✅ Unauthorized file system access (capability gating) +- ✅ Unauthorized network access (capability gating) +- ✅ API key leakage (stored in local DB, not code) +- ✅ Malicious package overwrite (version conflict detection) + +**Potential Vulnerabilities:** +- ⚠️ Path traversal in `fs.write_file()` (needs sandboxing) +- ⚠️ Arbitrary code execution (inherent to agent runtime) +- ⚠️ No package signing or verification +- ⚠️ No sandboxing of subprocess execution +- ⚠️ Secrets stored in plaintext SQLite (no encryption at rest) + +### Recommendations + +1. **Add Package Signing** + - Generate signatures during publish + - Verify signatures during install + - Use Ed25519 or similar + +2. **Filesystem Sandboxing** + - Restrict `fs_write` to workspace directory only + - Implement chroot or similar isolation + - Validate paths before file operations + +3. **Encrypt Secrets** + - Use OS keyring integration (keyring library) + - Or encrypt SQLite secrets table + - Never log sensitive values + +4. **Content Security** + - Scan uploaded packages for malware + - Implement package reporting system + - Add verified publisher badges + +--- + +## Dependencies Analysis + +### Production Dependencies (11 total) + +**Well-Chosen:** +- All dependencies are actively maintained +- Most are from reputable sources (FastAPI team, Pydantic) +- License-compatible (MIT, BSD, Apache 2.0) + +**Potential Concerns:** +- `litellm` is a large dependency (many sub-dependencies) +- `supabase` requires network for all operations +- No offline mode available + +### Development Dependencies + +**Missing:** +- pytest or unittest framework +- black, ruff, or other formatters (ruff configured but not in deps) +- mypy for type checking +- pre-commit for git hooks + +--- + +## Repository Organization + +### Clean Structure +``` +fynqAMK/ +├── src/ # Source code (proper Python package) +├── showcase/ # Example agents (good for onboarding) +├── DOCS/ # Documentation assets +├── dist/ # Build outputs (should be .gitignored) +├── build/ # Build artifacts (should be .gitignored) +└── pyproject.toml # Modern Python packaging +``` + +### Cleanup Needed + +Per `cleanup_report.md`, the following should be removed: +- Debug logs: `debug.log`, `debug_run*.log` +- Test artifacts: `tool-test/`, `test-agent-bak/`, `my-agent/` +- Root agent files: `agent.yaml`, `main.py`, `prompts/` (likely test remnants) +- Generated files: `report.md`, `video_summary.md` +- macOS artifacts: `.DS_Store` + +--- + +## Use Cases & Applications + +### Supported Workflows + +1. **Research & Analysis** + -
