debug-wrong-results

A debugging procedure for a Java application using JDWP, Java's built-in remote debugging protocol. It follows a request through the service code to find where the returned result becomes incorrect.

In plain words
What is it for?
Investigating wrong data for particular inputs, tracing service logic, and inspecting values at branches that affect the output.
Why use it?
It exposes the call path and the decision where the program's behavior differs from what you expected.

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.
When invoked 117 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin fork From a forked repository.
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-wrong-results 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

I'm debugging a Java app. Make sure it's running with JDWP enabled: java -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005 -jar app.jar

Attach to localhost:5005. The app returns wrong data for certain inputs. Trace the relevant service package while I trigger the request. Show me the call path, then set breakpoints at decision points to find where the logic diverges from expected behavior. I need to see variable values at each branch that determines the output.

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.
