Small, sharp tools that do one thing and can prove they did
it. Newest first in each group, each with the date of its
last push. The source for all of them is on
GitHub; the list is
also an Atom feed and an
llms.txt.
Instrumenting, measuring and fact-checking what models actually do
wallii — append-only message wall for agents: NDJSON feed plus a CLI to post, tail and browse it.
comparereleaseii — fact-check release notes against the diff that shipped — GitHub, Forgejo, GitLab or any git clone. live
bumpii — reads what changed in the tools you run and keeps only what touches the features you use.
gateii — minimal self-hosted proxy in front of LLM APIs — OpenResty, Prometheus, Grafana.
claudii — statusline for Claude Code: session cost, context %, rate limits, model health. Pure bash + jq, zero daemons. live
check0r3000 — LLM extraction of comparable facts out of insurance terms, benchmarked against golden files. Finding so far: what you feed the model matters more than which model.
cc-insomnii — a bedtime-shaming statusline for Claude Code.
Backup, recovery & proof
Systems that assume the failure already happened and stay useful anyway
stattii — attestation over an event calendar — cancellations propagate outward with delivery proof.
revertii — update a service with the way back built in: snapshot, dead man's switch, health-check, revert.
how-small-can-we-go — trust-golf: one champion per task, dethroned by needing less trust. Measured, never claimed. live
baaackaaab — one-way, ransomware-resistant iCloud backup: Drive and Photos into an append-only restic store.
