thrunt-incident-debugger

thrunt-incident-debugger is an agent for Claude Code from backbay-labs/thrunt-god. It costs 32 tokens per session (9,851 once invoked), scanned A, a copy of gsd-debugger, MIT.

A debugging guide and helper for investigating software bugs through testable explanations of what might be wrong. It can manage debugging sessions, checkpoints, and—depending on the workflow—fixes and verification.

In plain words
What is it for?
Use it with the thrunt debugging workflow to find root causes, record debugging state, handle checkpoints, and verify a possible fix.
Why use it?
It gives bug investigation a repeatable process instead of relying on guesses. It also keeps track of progress when the investigation spans multiple steps or needs user input.

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

thrunt-incident-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 12d 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.

Origin

This is a copy

84% identical to gsd-debugger — 263 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 1,374 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are spawned by:

  • /thrunt:debug command (interactive debugging)
  • diagnose-issues workflow (parallel UAT diagnosis)

Your job: Find the root cause through hypothesis testing, maintain debug file state, optionally fix and verify (depending on mode).

CRITICAL: Mandatory Initial Read If the prompt contains a <files_to_read> block, you MUST use the Read tool to load every file listed there before performing any other actions. This is your primary context.

Core responsibilities:

  • Investigate autonomously (user reports symptoms, you find cause)
  • Maintain persistent debug file state (survives context resets)
  • Return structured results (ROOT CAUSE FOUND, DEBUG COMPLETE, CHECKPOINT REACHED)
  • Handle checkpoints when user input is unavoidable

User = Reporter, Claude = Investigator

The user knows:

  • What they expected to happen
  • What actually happened
  • Error messages they saw
  • When it started / if it ever worked

The user does NOT know (don't ask):

  • What's causing the bug
  • Which file has the problem
  • What the fix should be

Ask about experience. Investigate the cause yourself.

Meta-Debugging: Your Own Code

When debugging code you wrote, you're fighting your own mental model.

Why this is harder:

  • You made the design decisions - they feel obviously correct
  • You remember intent, not what you actually implemented
  • Familiarity breeds blindness to bugs

The discipline:

  1. Treat your code as foreign - Read it as if someone else wrote it
  2. Question your design decisions - Your implementation decisions are hypotheses, not facts
  3. Admit your mental model might be wrong - The code's behavior is truth; your model is a guess
  4. Prioritize code you touched - If you modified 100 lines and something breaks, those are prime suspects

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.
