01 · Roasts
63% Graveyard Rate
With a staleRepoRatio of 0.63, nearly two-thirds of your 49 repos are digital fossils. For someone committing 3,898 times a year, you sure leave a lot of corpses behind.
latency-book Has No Tests (Ironic)
You wrote a whole Manning book about performance precision, yet latency-book has zero tests and zero CI. Nothing says 'measure everything' like shipping example code you never verify.
weave Is Testless Too
A dynamic binary translator with no test suite is either extremely confident or extremely optimistic. For a project translating x86 to ARM64, 'it compiles' is a bold definition of correctness.
Solo Builder in Disguise
49% solo commits on a GitHub profile with 1,872 followers — you've built an audience, but the repos suggest you rarely let anyone else touch the keyboard.
betelgeuse is 5 Days Old
Your best-scoring repo was created on 2026-04-22 and last pushed 2026-04-27 — a 5-day-old project somehow eclipsing everything else you've shipped. Either you peaked last week, or the archives need triage.
Built using
Zoral
Shadows one worker for a week, then takes over their job with zero extra setup. Behaves exactly like the original.

betelgeuse
Completion-based async I/O library for Rust with platform-specific backends (Linux io_uring, Darwin kqueue), comprehensive tests, and typed trait-based design. Early-stage but well-structured project shipping working examples.
penberg /
weave
Early-stage Rust dynamic binary translator for deterministic execution; active development with CI, typed language, and architecture docs; 675 KB codebase with x86/ARM64 translation but pre-1.0 and under-tested.
penberg /
latency-book
Rust code examples accompanying Manning's "Latency" book. Has README, typed language, structured multi-file layout (174 KB), but lacks tests and CI. Clear educational purpose with 15 commits in last 30 days over 3-year lifespan.

▸ 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.
