debugging

A hypothesis-driven method for investigating real runtime problems in programs or binaries, such as crashes, wrong responses, leaks, and stuck processes.

In plain words
What is it for?
Use it to debug crashes, silent failures, asynchronous behaviour, memory leaks, timing problems, and other runtime or reverse-engineering issues.
Why use it?
It turns unexplained failures into a series of testable possibilities and escalates to additional analysis when early investigations fail.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

debugging scanned grade A with 1 finding 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.

The scan reads SKILL.md. This mod also ships 3 executable files (references/scripts/dap.mjs, references/scripts/dap.test.ts, references/scripts/fixture-adapter.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

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.

debugging is a skill published in the GitHub repository code-yeongyu/oh-my-openagent (68,548 stars, last pushed today), with no licence file. It adds 248 tokens to every session and 3,243 once invoked, about $0.0012 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
