A command for investigating an existing software error using logs, database or queue information, request traces, and the relevant source code. It classifies the problem before following the error to its location.

Diagnosing HTTP, database, queue, and authentication problems, including application logs, failed jobs, requests, exceptions, queries, mail, and stack traces.

It gives a repeatable way to move from an error message to the code and system data that may explain it.

Per session 7 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 384 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.

Model	Per session	Once invoked
Fable 5.1	$0.00007	$0.00384
Opus 5	$0.00003	$0.00192
Sonnet 5	$0.00001	$0.00077
Haiku 4.5	$0.00001	$0.00038

Measured 6d ago against content hash 73f08e34e390, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-06, from the pricing page.

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 6d 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 - Investigate Errors

Investigate errors using available diagnostic tools.

Usage

/debug [error context]

Issue Classification

Error Type?
├── HTTP → Telescope requests, route logs
├── Database → Telescope queries, slow log
├── Queue → failed_jobs, Telescope jobs
└── Auth → Telescope requests, session

Investigation

1. Gather Context

If Herd MCP available (Laravel Herd Pro):

mcp__herd__get-logs                 # Application logs
mcp__herd__get-dumps                # Dump output

If Telescope MCP installed (lucianotonet/laravel-telescope-mcp):

mcp__laravel-telescope__requests    # HTTP with exceptions
mcp__laravel-telescope__exceptions  # Stack traces
mcp__laravel-telescope__queries     # Slow/failed queries
mcp__laravel-telescope__jobs        # Failed jobs
mcp__laravel-telescope__logs        # Application logs
mcp__laravel-telescope__mail        # Email issues

Fallback:

Read storage/logs/laravel.log
Search for error messages
Check failed_jobs table

2. Trace

Follow stack trace to file:line
Read surrounding code
Check related files

3. Report
