Jevlint — codegirl-007
A Go linter that checks code against plain-language rules: Tree-sitter extracts code units, then each one is sent to Jev or another configured decision provider to decide whether it passes, with caching and eval fixtures.

Highlights
- Commands: jevlint init, doctor, check, eval, plugin, and version; init and doctor accept --json for machine-readable output.
- The default provider is TypeSafe Jev, sending requests to api.typesafe.ai/v1/systemone with the jev-latest model by default.
- Other providers via JEVLINT_PROVIDER: typesafe, jev, cloudflare (Clef models), clef, openrouter, and openai; Clef keeps the same request and response shape.
- Building from source needs Go 1.26 or newer with CGO and a C compiler; prebuilt binaries cover linux and macos amd64/arm64 plus windows amd64.
- --changed checks only git-modified files, --concurrency defaults to 4 Jev requests, and --clear-cache or --refresh-cache manage cached evaluations.
Quickstart
bash
go install github.com/codegirl-007/jevlint/cmd/jevlint@latest
cd your-project
jevlint init
export TYPESAFE_API_KEY=apikey_...
jevlint doctor
jevlint check .Watch out
Copy reviewed against the repo README on 2026-10-15. The README documents commands, flags, providers, and configuration but publishes no accuracy, latency, or cost benchmarks for the decisions, and without rules in .jevlint.json the check command has nothing to evaluate. Credentials are read from environment variables only.
Questions about this entry
Short answers drawn from the linked project or page.
It checks code against plain-language rules. Tree-sitter extracts code units, each unit is sent to the configured decision backend to answer whether it passes, and findings print with confidence thresholds; exit code 0 means no failures above your thresholds.
Download a prebuilt binary from Releases for linux and macos on amd64 or arm64, or windows on amd64, and put jevlint on your PATH. Or install with Go using go install; building from source needs Go 1.26 or newer with CGO and a C compiler.
The default provider is TypeSafe: requests go to https://api.typesafe.ai/v1/systemone with the jev-latest model, using TYPESAFE_API_KEY. TYPESAFE_BASE_URL, TYPESAFE_ENDPOINT, and TYPESAFE_DEFAULT_MODEL adjust this, and JEVLINT_PROVIDER switches backends.
Any check that misses the cache is a decision request, and requests run with a default concurrency of 4; results are cached so repeated checks do not re-ask. The README states no pricing, and billing follows your chosen provider's terms.
Rules live in .jevlint.json, which jevlint init creates; legacy jevlint.json files are still read. jevlint plugin manages rule packs, and jevlint eval scores rules against fixtures in jevlint-evals.json.
Rules are plain-language yes/no questions judged by a decision model rather than hand-written AST checks, so taste rules are quick to phrase. It complements deterministic syntax linters, and it needs credentials for a decision provider before it can run.
codegirl-007 built it in Go under the MIT license; GitHub metadata shows it created 2026-09-25 and last pushed 2026-10-08. It is listed in both the logicrw and madewithjev collections.
