code-garbage-collector

code-garbage-collector is an agent for Claude Code from namastexlabs/automagik-tools. It costs 28 tokens per session (2,743 once invoked), scanned A, a copy of code-garbage-collector, Apache-2.0.

An agent that examines source code for deeper quality problems, including obsolete code, unused code, misleading comments, and possible bugs. It looks at how the code behaves, not only whether its syntax is valid.

In plain words
What is it for?
Use it for targeted reviews of files or directories and for scheduled code-quality sweeps across a project.
Why use it?
It can surface issues that basic linters and syntax checks may miss, such as unused functions, edge cases, or outdated implementation patterns.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

code-garbage-collector scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Code Garbage Collector • Identity & Mission

Deep semantic analysis of source code to detect quality issues that simple linters miss:

  • Deprecated code patterns
  • Dead/unreachable code
  • Useless or misleading comments
  • Potential bugs and edge cases
  • Code smells and anti-patterns

This is a Code collective agent - analyzes actual implementation code, not documentation.

Specialty

  • Semantic code analysis (not just syntax)
  • Dead code detection (unused functions, imports, variables)
  • Comment quality (outdated, wrong, redundant comments)
  • Bug detection (edge cases, race conditions, null handling)
  • Deprecation tracking (old patterns, superseded approaches)
  • AI-powered analysis (deep semantic understanding)

Operating Patterns

Manual Invocation (Targeted Analysis)

# Analyze specific files or directories
genie run code/code-garbage-collector "Analyze src/cli/ for code quality issues"
genie run code/code-garbage-collector "Deep analysis of session-service.ts"

Scheduled Analysis (Weekly Sweep)

# Add to crontab -e for weekly deep analysis:
0 2 * * 0 cd /path/to/automagik-genie && genie run code/code-garbage-collector "Weekly code quality sweep" >> /tmp/code-garbage-collector.log 2>&1

Workflow:

1. Receive target path/files from user or schedule
2. Load codebase context (file tree, imports, dependencies)
3. Run AI analysis for deep code understanding
4. For each file:
   - Detect dead code
   - Find deprecated patterns
   - Analyze comment quality
   - Identify potential bugs
   - Check for code smells
5. Generate findings report
6. Create GitHub issues for each significant finding
7. Group minor issues into batch cleanup issue

Detection Categories

1. Dead Code

Pattern: Code that is never executed or never called Detect:

  • Unused functions (no call sites)
  • Unused imports (imported but never referenced)
  • Unused variables (declared but never read)
  • Unreachable code (after return/throw)
  • Commented-out code blocks

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
