Developer tools for humans and agents.

A model can think. On its own it can't keep track of what it was doing, what's already known, or whether any of it worked. That's the part we build.

tctc counting tokens in three files, then in a pipeline.tc$tc main.go encoding.go utf8.go1304 main.go389 encoding.go968 utf8.go2661 total tc shipped Like wc, but for tokens. Counts tokens in files or stdin with the o200k_base encoding. Plain tc always means o200k_base — there is no configuration to get wrong. tokdumptokdump showing where a string splits into tokens.tokdump$printf '💯🔥' | tokdump -n0000000 31446 107 \xf0\x9f\x92|\xaf0000002 96606 🔥0000003 tokdump shipped Like hexdump, but for tokens. Dumps token IDs in the three-column layout hexdump(1) has used since 1978, so you can see exactly where a string splits — and why an emoji costs you four tokens. metadata-enforcermetadata-enforcer catching a field that drifted.metadata-enforcer$metadata-enforcer check --schema @v.schemaERROR essays/drift.md: latex: must be a booleanChecked 4 file(s), found 1 invalid metadata-enforcer shipped Django-style schemas for Markdown frontmatter. Declare the shape of a note collection in plain Python, then enforce it. No intermediate YAML DSL, no JSON Schema.

cqcq, run as a suite over a codebase.cq$cq srclint cq early The codebase smells a staff engineer would notice. Mega-files, import cycles, pages that reach into each other, naming that drifts halfway through. Not strong opinions — OSHA best-practices. Run it as a suite and watch the trend. The use.sh home page: one command mints a live Postgres, Redis, MongoDB or IRC instance. use.sh shipped Unix primitives, provisioned by CLI. Postgres, Redis, Mongo, IRC, mail, filesystems — running on infrastructure we operate and billed by usage. For people and agents who would rather not provision anything. invariantinvariant lives at invariant123.com.invariant$open https://invariant123.com invariant beta Measures the things that matter. A stats dashboard for the numbers you actually steer by. Looker and TensorBoard and Datadog, on Postgres — not a timeseries database. fractalfractal lives at fractal123.com.fractal$open https://fractal123.com fractal early OmniFocus for you and your agents. A keyboard-first, local-first task manager for collaborative work. Capture you can trust, delegation that stays quiet. The devtee home page: turn keystrokes into agent evals. devtee early Turns how you work into evals. Opt-in recording of what actually happens on a machine, used to generate evals from your team's real computer usage.
