debug

A command that gives structured help investigating difficult software errors. It analyzes the reported issue and suggests likely causes, investigation steps, and ways to resolve it.

In plain words
What is it for?
Use it to investigate errors such as a React data-rendering failure and receive root-cause analysis and resolution guidance.
Why use it?
It provides a repeatable debugging process when the cause of a problem is unclear, without writing debugging code.

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.

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 147 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 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 2d 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.

/debug TypeError: Cannot read property 'map' of undefined in React component during API data rendering

How it works

Analyzes errors and provides systematic debugging approach with root cause analysis, investigation steps, and resolution strategies.

Approach: Systematic debugging methodology to isolate and resolve issues effectively.

Changes

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.

debug is a command published in the GitHub repository neriousy/gemini-mcp (7 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 147 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
