Ghost of GitHub Past
9 commits in a year. Your heatmap looks like someone dropped a handful of pixels on a blank canvas and called it a portfolio. Peak output: 2 commits in a single Monday.
Broken Loop Detected
terminal_ppo's ppo.py literally has a training loop that ends mid-assignment — `unit_loss =` and then silence. You pushed a repo where the main function doesn't finish its own sentence.
The Solo Universe
0 external PRs, 0 issues opened, 0 forks received. Your GitHub exists in a sealed vacuum chamber. Even your followers (both of them) are probably bots or your own alt account.
ML Tourist
Three repos, all machine learning, all in the same two languages, all 0 forks. Incredible range — you went from chess AI to RL to numerical methods and somehow never left your own apartment.
License? Never Heard of Her
Not a single license file across any repo. parakeet trained on 36 million Lichess games with no license. Bold legal strategy for a Cambridge engineer.
Built using
Zoral
Shadows one worker for a week, then takes over their job with zero extra setup. Behaves exactly like the original.

parakeet
A MCTS chess engine trained on 36M Lichess positions using a 10-layer SE-CNN and PUCT search. Well-documented with architecture design, but minimal adoption (1 star), no tests, no CI/license, and no evidence of external use.
walterliu417 /
terminal_ppo
Personal research project implementing PPO reinforcement learning for Terminal game AI. Typed Python with structured codebase and documentation, but unfinished training loop and no test/CI infrastructure. ~110 KB repo with 30 recent commits.
walterliu417 /
numerical-programming
Personal learning project tracking numerical methods (FEM, LBM) with structured code, no tests/CI, minimal documentation beyond update log. Educational value but experimental stage.

▸ How the pipeline works
- 01Scrape.Pull every non-fork repo pushed in the last 90 days, plus your contribution calendar, followers, and language byte counts — straight from GitHub's REST & GraphQL APIs.
- 02Triage.A small model reads every repo's file tree + README and picks the 20 files per repo that actually reveal how you code.
- 03Grade each repo. All repos run in parallel through a fast scoring model that reads the picked files and rates each one independently on Impact, Quality, and Depth — with evidence citations.
- 04Aggregate. A larger reasoning model combines the per-repo scores with server-computed stats (heatmap, commit cadence, language entropy, follower count) to produce the 6-dimension profile score + roasts.
- 05Correct.Deterministic server-side checks enforce anchor-scale floors (e.g. a profile with 2,000+ public commits can't score 30 Consistency) and recompute the final verdict.
~90 seconds per profile, ~$0.25 in compute. Total of ~240 files read across your top-12 repos. One rating per GitHub account per day.
▸ Data sources & caveats
- Heatmap & commit totals: GitHub GraphQL
contributionsCollection— covers the last 365 days, includes private repos when the user has opted in (default). - Language %: byte totals across the top 30 owned non-fork repos.
- Curve: a small upward nudge centered on raw score ≈ 70, capping at 100. Prevents specialists from being unfairly penalised for narrow breadth.
- Anchor corrections: when server-measured signals (e.g. privateWorkLikely, multiRepoVolume, follower count) mandate a minimum category score, the aggregation step enforces it. These are signal-conditional, not identity-based floors.
