Debug

Debug is a skill for Claude Code, Codex from stagewise-io/stagewise. It costs 13 tokens per session (989 once invoked), scanned B, original, AGPL-3.0.

A debugging skill that uses logging calls and local log files to investigate program behaviour.

In plain words
What is it for?
Use it when diagnosing code by adding or reviewing logs and examining the resulting local log files.
Why use it?
It gives you a record of what happened during execution, which helps trace problems that are difficult to reproduce from the final error alone.

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 B, and why

Debug scanned grade B 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 5d 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

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.
