AI provenance describes how code was produced; it is not a quality judgment. Unless attribution is explicit, these are signals consistent with AI generation, not proof. Squash/rebase workflows, imported code, and rewritten history reduce accuracy.
Code quality
Code quality is adequate: test-to-source ratio 0.14, CI runs tests; 25% of function code in complex or long functions; 5% duplicated lines. Weakest area: type safety.
| Area | Score |
|---|---|
| Complexity (lizard) | 47 |
| Duplication | 72 |
| Code smells (Opengrep) | 80 |
| Tests and CI | 82 |
| Documentation | 100 |
| Type safety | 0 |
| Process (Scorecard review/maintenance) | n/a |
- Functions: 972; mean complexity 4.5, 90th percentile 10; 42 complex and 21 long functions
- Duplicated lines: 5.5% of 17,371 compared
- Tests: 3,204 test lines for 22,779 source lines (ratio 0.14); CI test commands: pytest, go test, cargo test; 95% of recent source commits also change tests
- Docs missing or thin: none
Most complex functions:
- api in demo/mock-api.js: complexity 70, 124 lines
- _dispatch in src/core/prompt_ui.py: complexity 66, 235 lines
- merge_index_config in rust/core/src/rag.rs: complexity 46, 191 lines
- merge_chat_defaults in rust/core/src/rag.rs: complexity 41, 150 lines
- validate_config in src/core/prompt_runtime.py: complexity 41, 85 lines
Security
Security posture is adequate: 14 known vulnerabilities in 7 dependencies; 4 high-severity SAST findings; 37 high-severity workflow issues. Weakest area: ci actions.
| Area | Score |
|---|---|
| Secrets (gitleaks, tree + history) | 100 |
| Static analysis (Opengrep) | 90 |
| Vulnerable dependencies (OSV) | 65 |
| CI workflows (zizmor) | 0 |
| Posture (policy, updates, signing, lockfiles) | 100 |
| OpenSSF Scorecard | n/a |
-
Known vulnerabilities: 14 in 7 packages (critical 0, high 2, medium 2, low 2)
-
Posture checks passed: security policy, dependency updates, signed commits; missing: lockfiles
Top findings
| Severity | Finding | Location |

| high | opengrep/python.lang.security.audit.dangerous-subprocess-use-audit: Detected subprocess function 'Popen' without a static string. If this data can be controlled by a malicious actor, it may be an instance of command injection. Audit the use of this call to ensure it is not controllable by an external resource. You may consider using 'shlex.escape()'. [confidence low] |
