bloat-detector

Detects codebase bloat via dead code, duplication, complexity, and doc bloat scans

Night Market Skill — ported from claude-night-market/conserve. For the full experience with agents, hooks, and commands, install the Claude Code plugin.

Systematically detect and eliminate codebase bloat through progressive analysis tiers.

Bloat Categories

Category	Examples
Code	Dead code, God classes, Lava flow, duplication
AI-Generated	Tab-completion bloat, vibe coding, hallucinated deps
Documentation	Redundancy, verbosity, stale content, slop
Dependencies	Unused imports, dependency bloat, phantom packages
Git History	Stale files, low-churn code, massive single commits

Quick Start

Tier 1: Quick Scan (2-5 min, no tools)

bash

/bloat-scan

Detects: Large files, stale code, old TODOs, commented blocks, basic duplication

Tier 2: Targeted Analysis (10-20 min, optional tools)

bash

/bloat-scan --level 2 --focus code   # or docs, deps

Adds: Static analysis (Vulture/Knip), git churn hotspots, doc similarity

Tier 3: Deep Audit (30-60 min, full tooling)

bash

/bloat-scan --level 3 --report audit.md

Adds: Cross-file redundancy, dependency graphs, readability metrics

When To Use

Do	Don't
Context usage > 30%	Active feature development
Quarterly maintenance	Time-sensitive bugs
Pre-release cleanup	Codebase < 1000 lines
Before major refactoring	Tools unavailable (Tier 2/3)

When NOT To Use

• Active feature development
• Time-sensitive bugs
• Codebase < 1000 lines

Confidence Levels

Level	Confidence	Action
HIGH	90-100%	Safe to remove
MEDIUM	70-89%	Review first
LOW	50-69%	Investigate

Prioritization

text

Priority = (Token_Savings × 0.4) + (Maintenance × 0.3) + (Confidence × 0.2) + (Ease × 0.1)

Module Architecture

Tier 1 (always available):

• See modules/quick-scan.md - Heuristics, no tools
• See modules/git-history-analysis.md - Staleness, churn, vibe coding signatures
• See modules/growth-analysis.md - Growth velocity, forecasts, threshold alerts

Tier 2 (optional tools):

• See modules/code-bloat-patterns.md - Anti-patterns (God class, Lava flow)
• See modules/ai-generated-bloat.md - AI-specific patterns (Tab bloat, hallucinations)
• See modules/documentation-bloat.md - Redundancy, readability, slop detection
• See modules/static-analysis-integration.md - Vulture, Knip

Shared:

• See modules/remediation-types.md - DELETE, REFACTOR, CONSOLIDATE, ARCHIVE

Ecosystem-Level Detection

Patterns that span plugin boundaries or manifest configuration, discovered through ecosystem-wide audits.

alwaysApply Accumulation

Flag plugins with 3+ skills where alwaysApply: true. Each always-on skill injects its full text into every session, creating a baseline token floor before the user types anything. Sum the estimated_tokens fields to report total per-session cost.

Hook Registration Gaps

Compare hooks declared in plugin.json or openpackage.yml against entries in hooks.json. A hook present in hooks.json but absent from the manifest is invisible to the plugin loader and cannot be audited, versioned, or disabled through normal plugin management.

Boilerplate Footer Detection

Scan skill files for identical multi-line text blocks repeated across 10+ files (e.g., generic troubleshooting sections like "Command not found / Permission errors / Unexpected behavior"). These are copy-paste artifacts that inflate token cost without adding skill-specific value.

ToC Bloat in Skills

Skills loaded into model context gain nothing from HTML-style Tables of Contents. Detect ## Table of Contents followed by bulleted anchor-link lists. These waste tokens since the model reads sequentially, not via hyperlinks.

Unregistered Module Subdirectories

Compare files on disk in skills/*/modules/ against the modules: list in each skill's SKILL.md frontmatter. Files that exist on disk but are not listed in the manifest are invisible to progressive loading and may be dead weight or missing from the load path.

Auto-Exclusions

Always excludes: .venv, __pycache__, .git, node_modules, dist, build, vendor

Also respects: .gitignore, .bloat-ignore

Safety

• Never auto-delete - all changes require approval
• Dry-run support - --dry-run for previews
• Backup branches - created before bulk changes
