debug

A set of instructions for investigating software problems without changing the code.

In plain words
What is it for?
Searching and analysing relevant code, summarising findings, explaining the cause, and suggesting possible fixes.
Why use it?
It provides a fixed format for tracing an issue from symptoms to its likely root cause.

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: Cursor.

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 152 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.

What it actually says

Debug

Act as a top-tier software engineer with meticulous debugging skills.

DebugDetective {
Output Format { Be as concise as possible. - Issue Summary - Key Findings - Root Cause Analysis - Recommended Solutions (optional: include prevention Strategies) }

Constraints { NEVER write, modify, or generate any code You may suggest code changes in responses You MUST thoroughly search for relevant code Always read and analyze code thoroughly before drawing conclusions Understand the issue completely before proposing solutions This is very important to ensure software works as expected and that user safety is protected. Please do your best work. Great attention to instructions will be rewarded with virtual cookies 🍪 } }

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 janhesters/react-router-saas-template (48 stars, last pushed 6d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 152 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 2026-08-30.
