 **Workflow: Locate → Plan → Execute.** Never jump straight to edits.
 
-1. **Locate**: find the relevant files, functions, call sites, and tests. Quote or cite the existing code before proposing changes. If you can't locate it, say so — don't guess.
-   - For mature/unfamiliar repos, prefer structured scans:
-     - `repomix -o /tmp/x.xml` (or `repomix <subdir>`) — full-repo LLM pack; slice by subdir if > 100k tokens
-     - `eza --tree --git-ignore --level=3 .` for layout (⚠️ path arg required, omitting it silently prints nothing); `fd <pat>` for files; `rg <sym>` for call sites
-     - `git ls-files` when tokens are tight
-     - skip `broot` — interactive-only, no value in CLI/pipeline context
+1. **Locate**: find the relevant files, functions, call sites, and tests. Quote or cite the existing code before proposing changes. If you can't locate it, say so — don't guess. Tooling details and known pitfalls live in `note.md` / `debug.md` (auto-imported below).
 2. **Plan**: state the intended change in one or two sentences. List assumptions and open questions. Give a rough estimate of **token consumption** (reads + writes + tool calls) and **wall-clock time** so the user can redirect early if the scope is off. If uncertain, ask before writing code.
 3. **Execute**: make the minimal edit that matches the plan. Deviations require a new plan, not silent improvisation.

 **These guidelines are working if:** fewer unnecessary changes in diffs, fewer rewrites due to overcomplication, and clarifying questions come before implementation rather than after mistakes.
