debt-hunter

A codebase scanner that finds common signs of technical debt—unfinished work, debug leftovers, empty functions, dead code, and weak naming—and then suggests cleanup priorities.

In plain words
What is it for?
Use it to scan a project for TODO or FIXME comments, debug statements, placeholder implementations, commented-out code, empty functions, and possible duplicate functions.
Why use it?
It helps reveal small problems that are easy to overlook and can make code harder to understand or maintain.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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

debt-hunter scanned grade A with 0 findings 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 2d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Technical Debt Hunter

Ruthlessly hunt down technical debt, code quality issues, and lazy implementations using the hybrid AI+Computer operations pattern.

Description

Scans the codebase for technical debt patterns using programmatic detection (ripgrep), then provides intelligent analysis and prioritized recommendations for cleanup.

Hybrid Pattern: CLI handles consistent pattern scanning, AI provides expert analysis and cleanup strategies.

Detection Patterns

Basic Technical Debt

  • TODO/FIXME comments - Incomplete work markers
  • Console debug logs - Debug artifacts left in code
  • Not implemented functions - Empty or placeholder implementations
  • Commented code blocks - Dead code that should be removed
  • Generic variable names - Lazy naming (data, item, thing, stuff)
  • Empty functions - Functions with no implementation
  • Debugger statements - Breakpoints left in production code
  • AI naming patterns - Similar function names (handle*, process*, manage*)

Duplicate Function Detection (Limited Heuristics)

  • Exact duplicates - MD5 hash comparison of function signatures
  • Similar names - AI-generated patterns like handleData/processData/manageData
  • Near-duplicates - 80%+ text similarity in function bodies
  • ⚠️ Limitations: Cannot detect semantic similarity or refactored duplicates

Usage

/fb:debt-hunter [scan_focus]

Examples:

  • /fb:debt-hunter - Full technical debt scan and analysis
  • /fb:debt-hunter high-priority - Focus on high-severity issues only
  • /fb:debt-hunter duplicates - Focus on duplicate function detection
  • /fb:debt-hunter comprehensive - Run both basic patterns and duplicate detection

CLI Commands Available:

  • flashback debt-hunter --scan - Basic technical debt patterns
  • flashback debt-hunter --duplicates - Duplicate/similar function detection (realistic heuristics only)
  • flashback debt-hunter --context - Output structured context for AI analysis

What this file has done since we first saw it

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.

debt-hunter is a command published in the GitHub repository agentsea/flashbacker (57 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 693 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
