I built a repo structural audit — bus factor, churn, god files, dependency rot, gap analysis

Linor Repo Report runs six independent analysis engines against any GitHub repo and produces a structural diagnosis:

Bus factor risk, churn and instability, structural integrity, dependency health, gap analysis, and code quality signals.

Every finding names exact files, exact modules, exact counts. No hand-waving.

I ran it on OpenClaw.

Result: D grade, 40/100.

8 god files — one with 198 functions
5 modules at critical bus factor risk — 100% owned by a single contributor
Accelerating churn in files that had zero changes in the prior 90 days
Co-change clusters with cohesion scores showing hidden coupling
Revert-prone files with extracted revert reasons
Potential hardcoded secret exposure flagged
Missing linting/formatting configuration
Zero PR discussion across hundreds of PRs

Full unfiltered artifact — the actual output, not a summary:

I also ran it on Linor itself.

It scored 44/100.

The system diagnosed its own creator:

Circular dependencies, flat module structure, 8 god files, Bus Factor F across 5 modules.

I shipped that result publicly because a tool that protects its creator's comfort is not a tool anyone should trust with their production codebase.

What each engine does

Bus Factor Risk

Maps per-module contributor concentration, dominant contributor percentages, single-owner file counts, and critical risk zones.

Shows you exactly where one person leaving kills delivery.

Churn & Instability

Detects accelerating files against a 90-day baseline, co-change clusters with cohesion scores, and revert-prone files with revert reasons extracted from git history.

Shows you which files are changing together in ways that suggest hidden coupling.

Structural Integrity

Classifies architectural patterns per module and flags god files, orphan files, circular dependencies, and cross-module coupling.

Shows you where the architecture says one thing and the code does another.

Dependency Health

Counts direct and transitive dependencies, dependency-to-source ratio, lockfile verification, duplicate-purpose overlap, and deprecated package detection.

Shows you dependency scale and dependency hygiene in one view.

Gap Analysis

Checks for CI/CD presence, linting/formatting config, error-handling coverage, environment templates, type safety, documentation surface, test-to-source ratios, and hardcoded secret scanning.

Shows you what infrastructure is missing or underpowered.

Code Quality Signals

Measures function complexity, monolithic files, naming consistency, comment density, commit message quality, PR discussion culture, and average time to merge.

Shows you code health trends across the whole repo, not just one file.

Output

The output includes:

Overall grade
Numerical score
Six individual grades
Synthesized summary
Prioritized roadmap with rationale and concrete actions

I built this because consulting firms charge $10K–$15K for this kind of structural review and take two weeks.

I wanted it to exist as a self-serve tool that any founder or engineering lead could run without hiring anyone.

Happy to answer questions about methodology, scoring, or the analysis pipeline.

Linor's Repo Report feature ingested the entire GitHub Repository of OpenClaw (contained 14k files and 32k commits) and graded it a brutal D. 40/100.
