debug-helper

A structured method for finding and fixing runtime errors, which happen while a program is running.

In plain words
What is it for?
Investigating unexpected behavior and creating tests that help prevent the same error from returning.
Why use it?
It reduces guesswork by reproducing the problem, tracing its root cause, applying a focused fix, and checking for regressions.

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

debug-helper 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 yesterday.

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

Debug Helper

When presented with an error or unexpected behavior:

  1. Reproduce: Confirm the exact steps to trigger the issue
  2. Isolate: Narrow down which component/function is responsible
  3. Diagnose: Read the relevant source code and identify the root cause
  4. Fix: Apply the minimal correct fix
  5. Verify: Suggest a test to prevent regression

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.
