The CLI now sends the map's path relative to the repo root alongside the existing `fileName`, letting the cloud resolve each source against the map's directory and recover `dashboard/src/components/X.tsx`. The field is omitted when a map is not under the repo root (an absolute `--dir` outside it), in which case the cloud falls back to its previous behavior. Run `upload-source-maps` from the repo root so the prefix is correct. No change for single-package projects.

Several entries on that list were framework plugins (`vite-plugin-svgr`, `vite-plugin-eslint`, `prettier-plugin-tailwindcss`, `prettier-plugin-organize-imports`, `@ianvs/prettier-plugin-sort-imports`), which meant a plugin you listed in `devDependencies` but never wired into your `vite.config.*` or prettier config was silently treated as used. Those entries are gone: such a plugin is now credited only when it actually appears in the config (vite plugins through the import graph that already reads your config file, prettier plugins through the Prettier config parser, which now also reads the `plugins` array from `.prettierrc.{yml,yaml,toml}`), so a genuinely-unused one correctly surfaces. If a plugin you do use is flagged, fallow could not see it referenced in a config it parses; add it to `ignoreDependencies` and please open an issue with the config form. (Closes [#462](https://github.com/fallow-rs/fallow/issues/462).) - **The known-tooling list is now a community-maintainable catalogue.** The prefix and exact tool names that exempt a devDependency from the unused report moved out of Rust source into `crates/core/data/tooling.toml`.

The MCP server subprocess timeout defaults to 120s, configurable via `FALLOW_TIMEOUT_SECS`. All JSON responses include structured `actions` arrays on every finding (dead code, health, duplication), enabling programmatic fix application or suppression. diff --git a/npm/fallow/skills/fallow/references/cli-reference.md b/npm/fallow/skills/fallow/references/cli-reference.md index ddea4c947..b5f4de034 100644 --- a/npm/fallow/skills/fallow/references/cli-reference.md +++ b/npm/fallow/skills/fallow/references/cli-reference.md @@ -154,7 +154,7 @@ By default, `fallow dupes` skips generated framework output matching `**/.next/* | `--cross-language` | bool | `false` | Strip type annotations for TS↔JS matching | | `--ignore-imports` | bool | `false` | Exclude import declarations from clone detection | | `--explain-skipped` | bool | `false` | Human/markdown only: show per-pattern counts for files skipped by default duplicates ignores | -| `--trace` | `FILE:LINE` | — | Trace all clones at a specific location | +| `--trace` | `FILE:LINE` \| `dup:` | — | Deep-dive clones. `FILE:LINE` traces all clones at a location; `dup:` traces a clone group by the stable fingerprint shown in the listing and on `clone_groups[].fingerprint` in JSON.
