Impact analysis
Deterministic code graphs — architecture, change and impact maps — with file:line on every edge, and recall verified by mutation testing instead of asserted.

Evidence-first tooling for AI coding agents.
Don't trust the model's self-report — check it. Every project here exists because an LLM asserted something that turned out to be false: a diagram that was an opinion, a judge score that could be bluffed, a benchmark number with no source.

What I do
Three problems, one rule: replace the claim with a check.
Every tool in this profile came out of the same failure mode — a plausible statement nobody could reproduce. The fix is mechanical: print the evidence, or don't publish the number.
Honest evaluation
Program gates before rubrics, paired statistics for the verdict, and a written statement of what the verdict cannot rule out. Zero dependencies.
Agent observability
Read what the agent actually did — turn by turn, token by token, with the cost column when the session reports one.
Featured work
Six of them, rendered from the index's own data file.
The cards below are read from projects/projects.json at
load time — the same file the project index and claims.json check against, so a card cannot
describe a project the index does not list.
Evidence, not widgets
These are outputs, not badges.
Rendered on a schedule from the tools' own results, and served from the image branch this repository publishes: codeblast's dependency graph, its mutation-tested recall, an AgentXRay per-turn ledger, and the contribution grid.
Writing
The newest things I published.
Post titles and dates come from the blog's front matter, listed in
blog/posts.json.
Everything here is source, and every number is a command.
This site is one repository: the pages, the data files they render, and the
claims.json that recomputes what the pages say. Push to main and Cloudflare
