--- description: Remove unused code from this project with ultrawork mode, LSP-verified safety, atomic commits --- Dead code removal via massively parallel deep agents. You are the ORCHESTRATOR — you scan, verify, batch, then delegate ALL removals to parallel agents. - **LSP is law.** Verify with `LspFindReferences(includeDeclaration=false)` before ANY removal decision. - **Never remove entry points.** `src/index.ts`, `src/cli/index.ts`, test files, config files, `packages/` — off-limits. - **You do NOT remove code yourself.** You scan, verify, batch, then fire deep agents. They do the work. NEVER mark as dead: - Symbols in `src/index.ts` or barrel `index.ts` re-exports - Symbols referenced in test files (tests are valid consumers) - Symbols with `@public` / `@api` JSDoc tags - Hook factories (`createXXXHook`), tool factories (`createXXXTool`), agent definitions in `agentSources` - Command templates, skill definitions, MCP configs - Symbols in `package.json` exports --- ## PHASE 1: SCAN — Find Dead Code Candidates Run ALL of these in parallel: **TypeScript strict mode (your primary scanner — run this FIRST):** ```bash bunx tsc --noEmit --noUnusedLocals --noUnusedParameters 2>&1 ``` This gives you the definitive list of unused locals, imports, parameters, and types with exact file:line locations. **Explore agents (fire ALL simultaneously as background):** ``` task(subagent_type="explore", run_in_background=true, load_skills=[], description="Find orphaned files", prompt="Find files in src/ NOT imported by any other file. Check all import statements. EXCLUDE: index.ts, *.test.ts, entry points, .md, packages/. Return: file paths.") task(subagent_type="explore", run_in_background=true, load_skills=[], description="Find unused exported symbols", prompt="Find exported functions/types/constants in src/ that are never imported by other files. Cross-reference: for each export, grep the symbol name across src/ — if it only appears in its own file, it's a candidate. EXCLUDE: src/index.ts exports, test files. Return: file path, line, symbol name, export type.") ``` Collect all results into a master candidate list. --- ## PHASE 2: VERIFY — LSP Confirmation (Zero False Positives) For EACH candidate from Phase 1: ```typescript LspFindReferences(filePath, line, character, includeDeclaration=false) // 0 references → CONFIRMED dead // 1+ references → NOT dead, drop from list ``` Also apply the false-positive-guards above. Produce a confirmed list: ``` | # | File | Symbol | Type | Action | |---|------|--------|------|--------| | 1 | src/foo.ts:42 | unusedFunc | function | REMOVE | | 2 | src/bar.ts:10 | OldType | type | REMOVE | | 3 | src/baz.ts:7 | ctx | parameter | PREFIX _ | ``` **Action types:** - `REMOVE` — delete the symbol/import/file entirely - `PREFIX _` — unused function parameter required by signature → rename to `_paramName` If ZERO confirmed: report "No dead code found" and STOP. --- ## PHASE 3: BATCH — Group by File for Conflict-Free Parallelism **Goal: maximize parallel agents with ZERO git conflicts.** 1. Group confirmed dead code items by FILE PATH 2. All items in the SAME file go to the SAME batch (prevents two agents editing the same file) 3. If a dead FILE (entire file deletion) exists, it's its own batch 4. Target 5-15 batches. If fewer than 5 items total, use 1 batch per item. **Example batching:** ``` Batch A: [src/hooks/foo/hook.ts — 3 unused imports] Batch B: [src/features/bar/manager.ts — 2 unused constants, 1 dead function] Batch C: [src/tools/baz/tool.ts — 1 unused param, src/tools/baz/types.ts — 1 unused type] Batch D: [src/dead-file.ts — entire file deletion] ``` Files in the same directory CAN be batched together (they won't conflict as long as no two agents edit the same file). Maximize batch count for parallelism. --- ## PHASE 4: EXECUTE — Fire Parallel Deep Agents For EACH batch, fire a deep agent: ``` task( category="deep", load_skills=["typescript-programmer", "git-master"], run_in_background=true, description="Remove dead code batch N: [brief description]", prompt="[see template below]" ) ``` Every deep agent gets this prompt structure (fill in the specifics per batch): ``` ## TASK: Remove dead code from [file list] ## DEAD CODE TO REMOVE ### [file path] line [N] - Symbol: `[name]` — [type: unused import / unused constant / unused function / unused parameter / dead file] - Action: [REMOVE entirely / REMOVE from import list / PREFIX with _] ### [file path] line [N] - ... ## PROTOCOL 1. Read each file to understand exact syntax at the target lines 2. For each symbol, run LspFindReferences to RE-VERIFY it's still dead (another agent may have changed things) 3. Apply the change: - Unused import (only symbol in line): remove entire import line - Unused import (one of many): remove only that symbol from the import list - Unused constant/function/type: remove the declaration. Clean up trailing blank lines. - Unused parameter: prefix with `_` (do NOT remove — required by signature) - Dead file: delete with `rm` 4. After ALL edits in this batch, run: `bun run typecheck` 5. If typecheck fails: `git checkout -- [files]` and report failure 6. If typecheck passes: stage ONLY your files and commit: `git add [your-specific-files] && git commit -m "refactor: remove dead code from [brief file list]"` 7. Report what you removed and the commit hash ## CRITICAL - Stage ONLY your batch's files (`git add [specific files]`). NEVER `git add -A` — other agents are working in parallel. - If typecheck fails after your edits, REVERT all changes and report. Do not attempt to fix. - Pre-existing test failures in other files are expected. Only typecheck matters for your batch. ``` Fire ALL batches simultaneously. Wait for all to complete. --- ## PHASE 5: FINAL VERIFICATION After ALL agents complete: ```bash bun run typecheck # must pass bun test # note any NEW failures vs pre-existing bun run build # must pass ``` Produce summary: ```markdown ## Dead Code Removal Complete ### Removed | # | Symbol | File | Type | Commit | Agent | |---|--------|------|------|--------|-------| | 1 | unusedFunc | src/foo.ts | function | abc1234 | Batch A | ### Skipped (agent reported failure) | # | Symbol | File | Reason | |---|--------|------|--------| ### Verification - Typecheck: PASS/FAIL - Tests: X passing, Y failing (Z pre-existing) - Build: PASS/FAIL - Total removed: N symbols across M files - Total commits: K atomic commits - Parallel agents used: P ``` --- ## SCOPE CONTROL If `$ARGUMENTS` is provided, narrow the scan: - File path → only that file - Directory → only that directory - Symbol name → only that symbol - `all` or empty → full project scan (default) ## ABORT CONDITIONS STOP and report if: - More than 50 candidates found (ask user to narrow scope or confirm proceeding) - Build breaks and cannot be fixed by reverting $ARGUMENTS
