deslop

name	deslop
description	Use when user wants to clean AI slop from code. Use for cleanup, remove debug statements, find ghost code, repo hygiene, deslop. Pulls analyzer-supplied slop-fixes (tracked artifacts, orphan exports, empty catches, tautological tests) and slop-targets (defensive cargo cult, bot-authored, wrapper towers, single-impl, stylistic outliers, semantic duplicates) when repo-intel exists; falls back to regex+AST detection otherwise.

deslop

Clean AI slop from code with certainty-based findings and auto-fixes.

Parse Arguments

const args = '$ARGUMENTS'.split(' ').filter(Boolean);
const mode = args.find(a => ['report', 'apply'].includes(a)) || 'report';
const scope = args.find(a => a.startsWith('--scope='))?.split('=')[1] || 'all';
const thoroughness = args.find(a => a.startsWith('--thoroughness='))?.split('=')[1] || 'normal';

Input

Arguments: [report|apply] [--scope=<path>|all|diff] [--thoroughness=quick|normal|deep]

• Mode: report (default) or apply

Detection Pipeline

Phase 0: Analyzer-Supplied Slop (when repo-intel exists)

When the repo has been analyzed (/repo-intel init or enrich), the analyzer pre-computes two query results that drop straight into the pipeline — no detection needed for the first, narrowed scan for the second.

slop-fixes — pinpoint structured fixes (Haiku-tier)

The analyzer-supplied fixes are HIGH-certainty, pre-located, and self-contained (file + line range + action + reason). They flow directly into the fixes array without re-running detection. Categories: tracked artifacts, stale CI configs, duplicate tooling, orphan exports, empty catches, tautological tests.

slop-targets — ranked Sonnet/Opus scan candidates

A scored list of files (Sonnet tier) and cross-file areas (Opus tier) where slop is likely. Used as the targetFiles input to the detection pipeline so we scan only suspicious files instead of everything. Suspect labels (defensive-cargo-cult / could-be-shorter / bot-authored / cliché-names / wrapper-tower / single-impl / high-bug-community / and — when the embedder is installed — stylistic-outlier / semantic-duplicate) let downstream tooling pick a tailored reviewer prompt per file.

The lib/repo-intel-signals module wraps both queries:

const signals = require('../../lib/repo-intel-signals');

const fixes = signals.getSlopFixes(cwd);          // {fixes:[…]} or null
const targets = signals.getSlopTargets(cwd);      // {targets:[…]} or null
const targetFiles = signals.targetsToFileList(targets);
const directFixes = (fixes?.fixes || [])
  .map(signals.toDeslopFix)
  .filter(Boolean);

When repo-intel is absent, all helpers return null and the pipeline falls back to the unguided (scan-everything) behavior. No agent action needed beyond passing targetFiles through to runPipeline().

Phase 1: Run Detection Script

The detection script is at ../../scripts/detect.js relative to this skill.

Run detection (use relative path from skill directory):

# If aiTargetFiles is available from Phase 0, pass them explicitly:
# node ../../scripts/detect.js file1.ts file2.ts --compact
# Otherwise scan everything:
node ../../scripts/detect.js . --compact --max 50

For deep thoroughness (includes CLI tools if available):

node ../../scripts/detect.js . --deep --compact --max 50

For diff scope (only changed files):

BASE=$(git symbolic-ref refs/remotes/origin/HEAD | sed 's@^refs/remotes/origin/@@' || echo "main")
# Use newline-separated list to safely handle filenames with special chars
git diff --name-only origin/${BASE}..HEAD | \
  xargs -d '\n' node ../../scripts/detect.js --compact

Note: The relative path ../../scripts/detect.js navigates from skills/deslop/ up to the plugin root where scripts/ lives.

Phase 2: Risk Weighting (Repo-Intel)

The pipeline automatically reads repo-intel data via lib/collectors/git.js and the slop-targets suspect labels (no agent action required). If repo-intel exists in the state directory, findings are enriched:

• test-gaps + bugspots: MEDIUM findings in untested high-bug files are escalated to HIGH
• slop-targets suspect: when a finding lands in a file flagged as defensive-cargo-cult or bot-authored, severity is bumped one level
• stylistic-outlier / semantic-duplicate (embedder only): findings in these files get a nlp:<suspect> annotation for the reviewer prompt

Phase 3: Aggregate and Prioritize

Sort findings by:

1. Certainty: HIGH before MEDIUM before LOW
2. Tier: analyzer-supplied (Phase 0) before pipeline-detected
3. Score: slop-targets score (descending) within same certainty
4. Severity: high before medium before low
5. Fix complexity: auto-fixable before manual

Phase 4: Return Structured Results

Skill returns structured JSON - does NOT apply fixes (orchestrator handles that). The merged result includes both analyzer-supplied fixes (Phase 0) and pipeline-detected findings (Phase 1/1b/2), with a source field per fix so consumers can tell them apart.

Certainty Levels

Level	Meaning	Action
HIGH	Definitely slop, safe to auto-fix	Auto-fix via simple-fixer
MEDIUM	Likely slop, needs verification	Review first
LOW	Possible slop, context-dependent	Flag only

Pattern Categories

HIGH Certainty (Auto-Fixable)

Analyzer-supplied (Phase 0, slop-fixes query):

• tracked-artifact: log files at root, .DS_Store, .swp/.bak/.orig, coverage/.nyc_output trees
• stale-ci-config: .travis.yml / appveyor.yml / .drone.yml when an active CI is also present
• duplicate-tooling: ESLint+Biome, Prettier+Biome, multiple JS lockfiles
• orphan-export: file exports with zero importers in the project graph (skips entry points)
• empty-catch (analyzer): TS/JS empty catch blocks, Python except: pass
• tautological-test: expect(x).toBe(x) assertions

Pipeline-detected (Phase 1, regex):

• debug-statement: console.log, console.debug, print, println!
• debug-import: Unused debug/logging imports
• placeholder-text: "Lorem ipsum", "TODO: implement"
• empty-catch (pipeline): Empty catch blocks without comment
• trailing-whitespace: Trailing whitespace
• mixed-indentation: Mixed tabs/spaces

MEDIUM Certainty (Review Required)

• excessive-comments: Comment/code ratio > 2:1
• doc-code-ratio: JSDoc > 3x function body
• stub-function: Returns placeholder value only
• dead-code: Unreachable after return/throw
• infrastructure-without-impl: DB clients created but never used

LOW Certainty (Flag Only)

• over-engineering: File/export ratio > 20x
• buzzword-inflation: Claims without evidence
• shotgun-surgery: Files frequently change together

Fix Types

These correspond to the autoFix values emitted by slop-patterns:

AutoFix Strategy	Action	Patterns
remove	Delete line	debug-statement, debug-import, placeholder-text
add_logging	Add proper error logging	empty-catch
replace	Replace with corrected code	mixed-indentation

Error Handling

• Git not available: Skip git-dependent checks
• Invalid scope: Return error in JSON
• Parse errors: Skip file, continue scan

Integration

This skill is invoked by:

• deslop-agent for /deslop command
• /next-task Phase 8 (pre-review gates) with scope=diff

The orchestrator spawns simple-fixer to apply HIGH certainty fixes.

Repo-Intel Data

Expected: the orchestrator (the command that spawned this agent) has already checked <stateDir>/repo-intel.json and either pre-fetched the data into your context or skipped (user declined to generate). Do not call AskUserQuestion here - subagents cannot interact with the user.

If the pre-fetched data is empty, proceed with the available context. The orchestrator has already made the decision on the user's behalf.
