Scan summary Repository scanned at 82.0/100 with 55.6% coverage. It contains 534 nodes across 0 cross-layer flows, written primarily in mixed languages. Engine surfaced 26 findings — concentrated in quality (13), software (11), security (2). Risk profile is high: 0 critical, 1 high, 5 medium. Recommended next step: open the quality layer findings first — that's where the highest-impact wins live.

Showing 21 of 26 actionable findings. Click TP / FP to vote on a finding's accuracy — votes adjust the confidence weighting and improve detection across the platform.

high System graph security security conf 1.00 Insecure pattern 'exec_used' in src/browser_harness/run.py:125
Found a known-risky pattern (exec_used). Review and replace if possible.

medium System graph quality Agent instructions conf 1.00 Agent authority lacks a verifier contract: agent-workspace/domain-skills/tasksquad-ai/agents.md
This agent instruction grants code or shell authority but does not state the verification gate that decides promotion. The recurring safe pattern is: LLM proposes; deterministic tests/build/security checks verify; only verified code promotes.

medium System graph quality Agent instructions conf 1.00 Agent instructions exist but release-hardening basics are missing
AI-coder instruction files were found, but the repo is missing ci. Treat this as a contract gap: the agent is guided, but the generated output is not yet guarded by the controls that make it repeatable.

medium System graph quality Integrity conf 1.00 Network/subprocess call without timeout or try/except — src/browser_harness/admin.py:316
`subprocess.Popen(...)` here lacks both a `timeout=` arg and an enclosing try/except. This is exactly the class of bug that took down our git-clone earlier (HTTP/2 stream cancel surfaced as a fatal). Add a `timeout=` and wrap in try/except, or use a wrapper that retries.
runtime safetyRobustness
medium System graph security Coverage conf 1.00 No auth library detected
The scanner did not find any standard auth library (JWT, OAuth, NextAuth, Auth0, etc.). The repo has auth/admin/session surface indicators, so auth may live in custom code, in a separate service, or be missing.
auth
low System graph quality Integrity conf 1.00 14 env vars used in code but missing from .env.example
Drift between code and config docs. The first few: `BH_AGENT_WORKSPACE`, `BH_DEBUG_CLICKS`, `BH_DOMAIN_SKILLS`, `BH_RUNTIME_DIR`, `BH_TMP_DIR`, `BU_AUTOSPAWN`, `BU_BROWSER_ID`, `BU_CDP_URL` + 6 more. Add them (with a placeholder/comment) to .env.example so onboarding doesn't break.
config drift
low System graph quality Debug conf 1.00 Debug logging residue appears in source files
Found 65 console/debugger/print-style debug statements in non-test source. This is a common fast-generation residue before production cleanup.
CleanupRepo hardeningGenerated repo pattern
low System graph quality Integrity conf 1.00 Near-duplicate function bodies in 2 places
Functions with the same first-5-line body hash: src/browser_harness/admin.py:run_doctor_fix_snap, src/browser_harness/admin.py:run_doctor This is *the* AI-coder failure mode (4× more duplication in vibe-coded repos — see https://jw.hn/ai-code-hygiene). Consolidate or document why they're separate.
duplicatesduplication
low System graph quality Integrity conf 1.00 Old/deprecated-named symbol `disable_old` in src/browser_harness/daemon.py:319
Names with suffixes like `_old`, `_v1`, `_deprecated` usually indicate replaced-but-not-removed code (typical AI-coder leftover). Confirm and delete, or rename if it's the active version.
