# deslop

Scans a change for what went stale: names of deleted files and flags, dead links, copied code. A small model confirms each finding before anything is fixed.

## What it does

deslop is git-based. It diffs the current branch against its merge base and reads only the lines the change touched, so a clean change costs nothing. The checks cover a lot of ground: `stale-mention` catches a file, flag or env var the change removed but other files still name; `missing-path` and `broken-anchor` flag citations and heading links that resolve to nothing; `changelog-missing` complains about a user-visible change with no entry under `Unreleased`. There are also checks for tests with no assertion, added code nothing calls, settings nothing reads, and duplicates of 60 tokens and 6 lines or more.

Every finding goes to `scripts/confirm.js`, which sends the flagged line plus two neighbours to a small model and keeps only what comes back confirmed. The model is picked in order: `--cmd`, then `DESLOP_SMALL_CMD`, then the `ladder.small` rung in Tower Crane's `project.json`. Only files inside the repository are read — a path that escapes it or goes through a symlink gets neither context nor a fix.

\`duplicate-code` and `complexity` skip tests, generated files and snapshot folders. Complexity is measured by the language's own linter: ruff for Python, the repo's eslint for JS/TS, golangci-lint for Go, clippy for Rust. No linter installed means that language lands under `skipped`, and the check quietly does nothing for it. Logic errors and races are left to a reviewer.
