debugger

debugger is a skill for Claude Code, Codex from SkiTemplar/ultron-control-center. It costs 14 tokens per session (172 once invoked), scanned A, original, MIT.

A debugging workflow for finding the underlying cause of failed tests, error logs, and stack traces.

In plain words
What is it for?
Use it to investigate software bugs, identify the offending line or change, and explain a verified fix.
Why use it?
It encourages reproducing failures and tracing them to the responsible change instead of guessing at fixes.

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

debugger 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 1mo 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

Debugger — ULTRON Skill

This is a starter template for the debugger skill. Edit freely.

When to use

(Describe the triggers this skill should match. Activate when diagnosing bugs, identifying root causes of failures, or analyzing error logs and stack traces.)

Workflow

  1. (First step — reproduce the failure deterministically.)
  2. (Second step — bisect or trace to the offending change / line.)
  3. (Final output expectation — explanation of root cause + verified fix.)

Changes

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.

debugger is a skill published in the GitHub repository SkiTemplar/ultron-control-center (2 stars, last pushed 9d ago), licensed MIT. It adds 14 tokens to every session and 172 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
