find-bugs

find-bugs is a skill for Claude Code, Codex from panbanda/omen. It costs 10 tokens per session (223 once invoked), scanned A, original, Apache-2.0.

A code-review helper that points to places where bugs are likely to be hiding.

In plain words
What is it for?
Use it to find risky files, code hotspots, BUG or FIXME comments, and related files that may fail together.
Why use it?
It narrows a large codebase to files and functions worth checking first, including complex logic, error handling, edge cases, and known bug markers.

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

find-bugs 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 4d 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.

What it actually says

Find Bugs Skill

Hunt for bugs in: {{.paths}}

Quick Start

# Get high-risk files (threshold 0.8 = high risk)
omen -f json defect

# Find hotspots
omen -f json hotspot

# Check for explicit markers
omen -f json satd | jq '.items[] | select(.category == "defect")'

Priority Order

  1. Defect probability > 0.8: Investigate first
  2. Hotspot score > 0.5: Review complex logic
  3. BUG/FIXME markers: Known issues
  4. Temporal coupling: Check related files

In Each File

  • Look for functions with cognitive > 20
  • Check error handling paths
  • Review boundary conditions

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.
