Highlights
- jeff check runs read-only over the current directory or given paths, with --config, --output-format text|json and --no-cache flags.
- jeff auth login stores the TypeSafe credential the checks use; jeff auth logout removes it.
- Releases cover Linux, macOS and Windows on amd64 and arm64, with checksums.txt verified before install.
- jeff update installs the latest compatible GitHub release over the running binary.
- The README's install paths put the binary in ~/.local/bin on Unix and $HOME\bin on Windows.

Questions about this entry
Short answers drawn from the linked project or page.
jeff is a read-only Go CLI that semantically checks your files against your own rules using Jev, locally or in CI. It reports issues rather than fixing them, and jeff check takes --config, --output-format text|json and --no-cache flags.
Download the archive and checksums.txt from the latest GitHub release, choosing amd64 or arm64. On Linux and macOS the README installs the binary into ~/.local/bin after verifying the SHA-256 checksum; on Windows it uses PowerShell into $HOME\bin, then you add the directory to PATH.
Yes. jeff auth login stores the TypeSafe credential the semantic checks call, and jeff auth logout removes it. The README does not state pricing, and the digest excerpt does not show the credential format or any free-tier details.
GitHub releases cover Linux, macOS and Windows on amd64 and arm64, and you can build from source with go build -o "$HOME/.local/bin/jeff" ./cmd/jef. jeff update can replace the released binary with the latest compatible build.
No, the README describes it as read-only: it checks files and reports findings in text or JSON, but makes no edits. The excerpt is truncated inside the from-source section and shows no rule-file examples, so the rule format is not documented in the digest.
It is semantic rather than syntactic: rules are checked against your files with Jev's structured decisions, and results are cached between runs unless you pass --no-cache. The digest does not show example rules, so how far beyond a linter it goes could not be measured.
The owner is Alurith; the repo has 38 stars and 4 forks, is written in Go, licensed Apache-2.0, created 2026-09-18 and last pushed 2026-09-20. Version 0.1.0 is the release used in the README's install commands.

tools4imps/qualmGoAn unofficial Go CLI that puts Jev in a coding agent's toolbox: the agent can ask where an answer lives and read only those lines, or hand Jev a yes/no or multiple-choice call and get a calibrated verdict tuned to the cost of a wrong call.

aurorainfra/grevGoA Go CLI by dorkitude that skims pages, files, and lists with Jev, keeping only the chunks that help with your stated goal. The README's example kept 4 of 40 chunks and cut 71k characters to 7.6k, an 89% saving, for whatever agent reads next.

dorkitude/skimmerGo
dorkitude/skimmerGoA type-aware TypeScript linter that pins a public typescript-go compiler module and runs syntax- and type-aware rules in one AST pass per root file; its semantic mode reads changed files and asks TypeSafe Noul questions over bounded spans and candidates per policy.

A customizable linter that asks decision models like Jev and Clef your fuzzy rules — does the comments in this file repeat what the code says? — in a single Go binary with no runtime and minimal dependencies.
