De Slop

De-Slop Skill

Remove AI-generated artifacts before committing or creating PRs. Uses desloppify for quantitative scoring and directed fixes when available; falls back to LLM-based pattern detection otherwise.

When to Use

This skill should be invoked when the user:

• Says "de-slop", "clean up slop", "remove AI artifacts", or "clean before commit"
• Is about to commit changes and mentions cleaning/reviewing code
• Asks to check for unnecessary comments, TODOs, or files
• Wants to prepare code for PR by removing AI-generated artifacts
• Is at end of /sdlc:implement and the de-slop gate is triggered

Primary Workflow (desloppify-powered)

0. Check desloppify availability

uvx desloppify --version

If this fails, fall back to the LLM-based Workflow below.

1. Install/update workflow guide (once per session)

uvx desloppify update-skill claude

Follow the output — it installs the workflow guide into context. Do not augment or override the instructions it provides.

2. Scan the target path

Determine the path to scan. Default is . unless the user specifies otherwise.

uvx desloppify scan --path {path}

Read the scan output carefully. It contains:

• Strict score — quantitative measure of AI artifact density
• Issue list — specific findings with file and line references
• Agent instructions — follow these verbatim; do not augment or reinterpret

Record the before score for the final report.

3. Iterative fix loop

Run next until there are no more issues:

uvx desloppify next

Each call to next tells you:

• Which file to edit
• What issue to fix
• The resolve command to run after fixing

For each issue:

1. Fix it using the Edit tool (show before/after)
2. Run the resolve command given by next
3. Call next again

Repeat until next reports no more issues.

Safety rules during fix loop:

• Never touch README.md, CONTRIBUTING.md, CHANGELOG.md
• Never auto-delete test files — flag them for manual review instead
• Show before/after for every code edit
• When unsure whether a change is correct, flag it rather than auto-fix

4. Final scan

uvx desloppify scan --path {path}

Report before score → after score.

Fallback Workflow (LLM-based)

Use this when uvx desloppify --version fails.

1. Determine Comparison Base

Ask user what to compare against (or use sensible default):

• No args: Compare against main/master branch
• Branch name provided: Compare against that branch

# Get default branch
git remote show origin | grep "HEAD branch" | cut -d ":" -f 2 | xargs

# Get changed files
git diff --name-only {BASE}...HEAD

# Get change summary
git diff --stat {BASE}...HEAD

If no remote, fall back to:

git diff --name-only main...HEAD
# or
git diff --name-only master...HEAD

2. Scan for Slop Patterns (Dry Run Only)

Scan all changed files for these patterns. DO NOT modify anything yet.

A. Unnecessary Markdown Files

Flag for deletion:

• Filenames matching: NOTES.md, PLAN.md, ARCHITECTURE.md, THOUGHTS.md, IDEAS.md, SCRATCH.md, TEMP.md, TODO.md
• Case-insensitive match
• Only if they appear in changed files

Never touch:

• README.md, CONTRIBUTING.md, CHANGELOG.md
• Anything in docs/** directory
• Any markdown with specific project purpose

B. Redundant Comments

Comments that just restate what the next line obviously does:

Python example:

# Create user  ← Redundant
user = User()

# Save to database  ← Redundant
db.save(user)

TypeScript example:

// Initialize the counter  ← Redundant
const counter = 0;

// Return the result  ← Redundant
return result;

Detection:

• Single-line comment immediately before code
• Comment essentially restates the code
• Adds no context, reasoning, or "why"

C. AI TODO Comments

Pattern: # TODO: (Add|Consider|Might|Should|Could|May|Probably)

Examples to flag:

# TODO: Add error handling
# TODO: Consider edge cases
# TODO: Might need optimization
# TODO: Should validate input

Keep these (specific/actionable):

# TODO: Handle timezone conversion for EU users (ticket #123)
# TODO: Replace with new API endpoint after v2 launch

D. Excessive Docstrings

Flag docstrings that are excessively long for trivial functions.

Check for:

• Function has ≤5 lines of actual code
• Docstring has >3 lines
• Docstring just restates what code obviously does

Bad example:

def get_name(self) -> str:
    """Get the name property.

    This method returns the name property of the object.
    It retrieves the stored name value and returns it to the caller.
    The name is a string representing the object's name.

    Returns:
        str: The name of the object
    """
    return self.name

Good docstring (keep):

def parse_date(s: str, tz: str = "UTC") -> datetime:
    """Parse date string with timezone handling.

    Supports ISO 8601 and common formats. Falls back to UTC
    if timezone parsing fails.
    """

E. Mock-Heavy Tests

Flag tests with excessive mocking that test nothing real.

Pattern:

• Count @patch decorators per test function
• Flag if >3 patches
• Note: CLAUDE.md says "no mocking in tests"

F. Fake Data in Comments/Docs

Flag suspiciously specific claims without citation:

Patterns:

• "according to studies" (no link)
• "research indicates" (no source)
• "X% of users" (no citation)
• Specific performance metrics without benchmark

3. Present Findings with Numbered Selection

Display all findings with clear numbering and actions:

Scanned X files, found Y slop patterns

[1] NOTES.md (45 lines)
    → DELETE: Unnecessary markdown file

[2] src/user.py:23-28 (6 lines)
    → REMOVE redundant comments

[3] src/api.py:15-25 (11 lines)
    → SIMPLIFY excessive docstring on get_name()

[4] src/utils.py:42
    → REMOVE AI TODO: # TODO: Add error handling

[5] tests/test_user.py:50-70 (test_create_with_mocks)
    → FLAG: Mock-heavy (5 @patch decorators)
    Review manually

---
Select items to clean:
  • Enter numbers: 1 2 4
  • Range: 1-4
  • 'all' - clean items 1-4 (skips flags)
  • 'none' - cancel

Selection: _

• Show ±3 lines of context for code issues
• Separate "actions" (delete/remove/simplify) from "flags" (review needed)
• "all" only applies to action items, never flags

4. Execute User Selection

Parse user input (numbers, ranges, 'all', 'none').

For file deletions: git rm {FILE}

For code cleanup: Use Edit tool to remove redundant comments, simplify docstrings, remove AI TODOs. Show before/after for each edit.

For flagged items: Display file path and line numbers, ask user to review manually.

5. Summary Report

Cleaned:
  • 2 files deleted
  • 12 redundant comments removed
  • 3 docstrings simplified
  • 8 AI TODOs removed
  • 67 total lines removed

Flagged for manual review:
  • tests/test_user.py:50-70 (mock-heavy, 5 patches)

Next steps:
  1. Review flagged items (if any)
  2. Run tests: bun test
  3. Verify changes: git diff
  4. Commit: /commit

Safety Rules

Always follow these regardless of workflow:

1. Never touch: README.md, CONTRIBUTING.md, CHANGELOG.md, docs/**, test files (only flag)
2. When unsure: Flag for review, don't auto-fix
3. Show before/after for all code changes
4. Confirm before deleting >5 files or removing >50 lines total
5. Preserve formatting: Keep indentation when removing comments
