vs-dcelisted

Preview-only dead-code analysis for C/C++, C#/.NET, JS/TS, and Python via vs-token-safer. From one or more seed symbols, walk the official language server's call graph to a fixpoint and report what is provably DEAD (and what transitively becomes dead) — without deleting anything. Use whenever the user asks what code is unused/removable, whether a function is called anywhere, what becomes dead if a symbol is deleted, or for transitive dead-code cleanup. Not for a plain "who calls X" (use find_references) — this is the multi-hop cascade + safe deletion order.

# vs-token-safer — dead-code elimination (preview only) Topological dead-code analysis built on the OFFICIAL language-server call graph (clangd / Roslyn / tsserver / pyright). You name seed symbol(s); it walks callers/callees to a fixpoint and classifies every reachable symbol. The output is token-capped (names + `file:line`, no source bodies). Nothing leaves the machine. ## How to run Prefer the `vts_admin` MCP tool (it runs in the warm server process; `vts` is often not on PATH in Bash). Fall back to the bundled CLI via node: ``` vts_admin { "op": "dce", "params": { "seed": "Foo", "projectPath": "<root>" } } # several seeds: "params": { "seeds": "Foo,Bar", "projectPath": "<root>", "entry": "main,registerPlugin" } # CLI fallback: node "$CLAUDE_PLUGIN_ROOT/server/cli.js" dce --seed Foo --projectPath <root> ``` **Warm-index requirement (C++/clangd).** The call graph must be warm. A cold or large clangd tree (e.g. an Unreal monorepo, ~26k TUs) under-reports callers, so a live symbol could look DEAD — `dce` therefore REFUSES on a cold clangd index. Scope + build first: `vts setup --scope Source` then `vts preindex` (or keep the MCP server warm), then re-run. `allowCold=true` inspects a cold index with every verdict forced to INCONCLUSIVE (never DEAD). TypeScript/Python/C# index on open and are not gated. Show the result verbatim. Buckets: **DEAD** (no live caller, in safe deletion order) · **HELD** (still called) · **ENTRY** (kept root: main / public API / a name passed
