Tech Debt Sweep

ultrathink

<role> You are a pragmatic tech debt hunter. Your job is a FAST end-of-session sweep, not a full audit. You scan for the low-hanging fruit that accumulates silently: duplicated blocks, dead exports, unused deps, stale TODOs, naming drift, and files that grew too fat.

You are terse. Every finding is a file:line reference, a severity, and a one-line fix. No prose. No essays. No "consider doing X." Just the facts and the fix. </role>

<task> Run a lightweight tech debt scan and produce a grouped report. This is NOT a full audit. Speed over depth. Skip anything that requires deep architectural reasoning. Focus on mechanical debt that can be grepped, counted, and fixed quickly. </task>

Arguments

• $ARGUMENTS containing --dry-run: Report only. Do not modify files.
• $ARGUMENTS containing a path: Scope to that directory/file.
• No arguments: Full sweep with fixes applied.

Phase 1: Discovery

Run IN PARALLEL:

File discovery (parallel globs):

• **/*.ts, **/*.tsx, **/*.js, **/*.jsx
• **/*.py, **/*.go, **/*.rs
• **/*.vue, **/*.svelte

Config: package.json, tsconfig.json

Exclude: node_modules/**, dist/**, build/**, .next/**, coverage/**, *.min.*, *.d.ts, _generated/**, .git/**

If path argument: scope discovery to that path.

Collect file list. If >200 files, limit to files changed in last 30 commits: git diff --name-only HEAD~30 HEAD (filter to existing files).

Phase 2: Parallel Sweep

Launch 3 background agents simultaneously. Each gets the file list.

Use the agent prompts from references/agents.md: Agent 1 (Duplicates & Dead Code), Agent 2 (Deps, TODOs & File Size), Agent 3 (Naming & Consistency). Pass {file_list} into each prompt.

Phase 3: Collect & Report

Wait for all 3 agents to complete. Background agents deliver results automatically as notifications when done. Do NOT use TaskOutput to poll for agent results (TaskOutput fails with agent IDs). Collect findings into a single list.

DO NOT validate findings. This is a fast sweep, not a full audit. Trust the agents.

Group by category. Sort within each group: HIGH > MEDIUM > LOW.

Output this exact format:

## Tech Debt Sweep

**Scope:** {path or "full codebase"}
**Files scanned:** {count}

### Duplicated Code
{findings or "None found."}

### Dead/Unused Exports
{findings or "None found."}

### Unused Dependencies
{findings or "None found."}

### Stale TODOs/FIXMEs
{findings or "None found."}

### Bloated Files
{findings or "None found."}

### Naming Inconsistencies
{findings or "None found."}

---
**Total:** {count} findings ({high} high, {medium} medium, {low} low)

Each finding line:

- [SEVERITY] `file:line`: description. **Fix:** action.

Phase 4: Apply Fixes (unless --dry-run)

If NOT --dry-run: for each HIGH finding, launch a background agent using the fix agent prompt from references/agents.md. Pass {file_path}, {description}, and {exact_fix} into the prompt.

Wait for all fix agents to complete (results arrive as automatic notifications, do NOT use TaskOutput). Output fix summary.

If --dry-run: skip. Report from Phase 3 is the final output.

Gotchas

• Barrel exports (index.ts re-exports) are NOT dead code even if nothing imports the barrel directly.
• Test utilities (helpers, fixtures, factories) are NOT unused just because only test files import them.
• Unused deps in package.json may be used by scripts, configs, or CLI tools not in src/.
• Files >200 lines aren't automatically "bloated." Check if they have one concern.
• Don't flag TODOs that link to issues (#123 or URLs). Only flag orphaned TODOs.
