Agent Skills: De-Sloppify

De-Sloppify

Overview

De-Sloppify implements a two-agent pattern for code cleanup:

1. Implementer — works freely, writes code without worrying about polish
2. Cleanup Agent — runs after implementation, removes all slop without touching logic

This separation prevents "cleanup anxiety" from slowing down implementation while still producing clean final code.

When to Use

Skill({ skill: 'de-sloppify' });

Invoke when:

• Implementation is complete but the code contains known slop (unused imports, leftover console.logs, commented-out code)
• Before committing a feature branch
• After a rapid prototyping session
• As a post-implementation cleanup gate

Iron Law

CLEANUP AGENT MUST NOT CHANGE BEHAVIOR.
Every removal must be verifiable as dead code, unused import,
or formatting-only. If there is any doubt — LEAVE IT.

What Gets Cleaned

| Category | Examples | Safe to Remove | | ------------------------ | -------------------------------------------- | -------------- | | Unused imports | import foo from 'foo' — never referenced | YES | | console.log / debug | console.log('debug here'), console.error | YES | | Commented-out code | // const old = foo() (code, not docs) | YES | | Dead code | Unreachable branches, unused variables | YES | | Trailing whitespace | Spaces at end of lines | YES | | Extra blank lines | 3+ consecutive blank lines | YES | | TODO with no context | // TODO (no ticket, no description) | On flag only |

What Must NOT Be Cleaned

| Category | Why | | ------------------------ | --------------------------------------------- | | Commented doc blocks | /** ... */ JSDoc, /* ... */ section notes | | console.error in catch | May be intentional error logging | | Disabled test blocks | // it.skip(...) — intentional | | Feature-flag dead code | May be awaiting activation | | Complex logic | Even if it looks unused — leave it |

Workflow

Phase 1: Implementer Works Freely

The implementer completes the feature without cleanup overhead. This is normal development.

Phase 2: Cleanup Agent Runs

After implementation, invoke de-sloppify. The cleanup agent runs these checks in order:

Step 1: Snapshot Pre-Cleanup State

Command:

git diff HEAD -- {{target_files}} > C:/dev/projects/agent-studio/.claude/context/tmp/pre-cleanup-snapshot.diff

Expected output: A diff file capturing current state.

Verify: File exists at .claude/context/tmp/pre-cleanup-snapshot.diff.

Step 2: Find Unused Imports

Command (JavaScript/TypeScript):

node C:/dev/projects/agent-studio/.claude/skills/de-sloppify/scripts/main.cjs \
  --action find-unused-imports \
  --files "{{comma_separated_file_paths}}"

Expected output: JSON array of { file, line, import } objects for unused imports.

Verify: Exit code 0 and valid JSON array.

Step 3: Find Console Logs

Command:

node C:/dev/projects/agent-studio/.claude/skills/de-sloppify/scripts/main.cjs \
  --action find-console-logs \
  --files "{{comma_separated_file_paths}}"

Expected output: JSON array of { file, line, statement } objects.

Verify: Exit code 0 and valid JSON array.

Step 4: Find Commented-Out Code

Command:

node C:/dev/projects/agent-studio/.claude/skills/de-sloppify/scripts/main.cjs \
  --action find-commented-code \
  --files "{{comma_separated_file_paths}}"

Expected output: JSON array of candidate commented-out code blocks.

Verify: Exit code 0 and valid JSON array.

Step 5: Apply Cleanup

For each finding that is safe to remove, use Edit to remove the line(s). Apply changes conservatively — when in doubt, leave it.

Step 6: Format and Lint

Command:

cd C:/dev/projects/agent-studio && pnpm lint:fix && pnpm format

Expected output: 0 errors, 0 warnings from lint; no changes from format.

Verify: Both commands exit 0 with no output indicating issues.

Step 7: Generate Cleanup Diff

Command:

git diff -- {{target_files}}

Expected output: A diff showing only removals (lines starting with -). No additions should appear unless they are indentation fixes.

Verify: Review the diff — confirm every removed line was dead code or formatting. If any functional line was removed, revert with git checkout -- <file>.

Step 8: Report

Produce a cleanup summary:

De-Sloppify Report
==================
Files processed: N
Unused imports removed: N
Console.logs removed: N
Commented-out code blocks removed: N
Dead code blocks removed: N
Formatting fixes applied: N

Diff: git diff HEAD -- <files>

Anti-Patterns

• Never remove a console.error inside a catch block without confirming it is debug-only
• Never remove commented code that contains a ticket reference or TODO explanation
• Never run cleanup on uncommitted work from the implementer — take a snapshot first
• Never combine cleanup and logic changes in the same commit
• Never use regex to find "unused" code — use the CLI scanner or lint output only

Enforcement Hooks

Input validated against schemas/input.schema.json before execution. Output contract defined in schemas/output.schema.json.

Pre-execution hook (hooks/pre-execute.cjs) validates:

• action is a known enum value
• files is a non-empty array of paths

Post-execution hook (hooks/post-execute.cjs) emits observability event to .claude/context/runtime/tool-events.jsonl.

Assigned Agents

• developer — runs cleanup after implementation
• code-simplifier — incorporates de-sloppify as a cleanup step
• code-reviewer — recommends de-sloppify when reviewing slop-heavy PRs
• qa — verifies cleanup did not alter behavior

Memory Protocol

Before starting: Read .claude/context/memory/learnings.md for cleanup patterns specific to this codebase.

After completing: Append summary to .claude/context/memory/learnings.md:

**de-sloppify** — [date] Cleaned N files. Removed: M unused imports, K console.logs, J commented blocks.

ASSUME INTERRUPTION: Your context may reset. If it's not in memory, it didn't happen.
