Debug Using Debugbar

What it does

When your agent uses it

• Investigating a bug
• Duplicate query problem
• Slow SQL statement
• Unexpected status code

Example prompts

• “debugbar”
• “profiling”
• “/debug-using-debugbar”

Requirements

• Compatibility (from SKILL.md): Requires Laravel with fruitcake/laravel-debugbar installed, debug mode enabled, and `debugbar.storage.enabled` set.

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

1. 1Find the relevant request
2. 2Inspect the request summary to see which collectors have data
3. 3Drill into the relevant collector based on the issue type
4. 4For query issues, use dedicated query analysis
5. 5Trace the problem to source code using backtraces, then fix and re-test.

What it can do on your machine

Read from SKILL.md and the folder at commit 4113c36. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • php

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

• Compatibility

  Requires Laravel with fruitcake/laravel-debugbar installed, debug mode enabled, and `debugbar.storage.enabled` set.

  From compatibility in the SKILL.md frontmatter.

Context cost

Debug Using Debugbar loads about 1.5k tokens when it runs. Until then it costs about 128 tokens; SKILL.md has 478 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~128

When it runs · the whole SKILL.md, loaded when a task matches

~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

debug-using-debugbar

description

Inspect what a Laravel request actually did — queries, exceptions, timing, cache, auth, views — by reading the profiling data Laravel Debugbar already captured, via Artisan commands. Use when investigating a bug, a slow page or endpoint, an N+1 or duplicate query problem, a failing or slow SQL statement, a 500 or unexpected status code, or when asked to optimize a request. Also covers queued jobs and Artisan commands. Applies even when the user does not mention "debugbar" or "profiling".

compatibility

Requires Laravel with fruitcake/laravel-debugbar installed, debug mode enabled, and `debugbar.storage.enabled` set.

# List recent requests (shows summary with status, duration, memory, query count)
php artisan debugbar:find

# Filter by URI pattern (fnmatch) and/or HTTP method
php artisan debugbar:find --uri="/api/*" --method=POST

# Only show requests with issues (exceptions, slow queries, duplicates, errors)
php artisan debugbar:find --issues --max=50

# Customize issue thresholds (defaults: --min-queries=50, --min-duration=1000, --min-duplicates=2)
php artisan debugbar:find --issues --min-queries=10 --min-duration=500

# Threshold options also work standalone, filtering on just that criteria
php artisan debugbar:find --min-queries=20

php artisan debugbar:find --method=JOB      # queued jobs
php artisan debugbar:find --method=CLI      # artisan commands

# Summary of all collectors (available collectors depend on config)
php artisan debugbar:get latest
php artisan debugbar:get {id}

# Full data for a specific collector
php artisan debugbar:get {id} --collector=exceptions

# Overview with duplicate detection, slow flags and failed statements
php artisan debugbar:queries {id}

# Backtrace and params for a specific statement
php artisan debugbar:queries {id} --statement=N

# EXPLAIN plan or re-execute a SELECT
php artisan debugbar:queries {id} --statement=N --explain
php artisan debugbar:queries {id} --statement=N --result

php artisan debugbar:find --issues --json     # array of requests, each with an `issues` list
php artisan debugbar:queries {id} --json      # statements plus `duplicate_groups` and `n_plus_one_groups`
php artisan debugbar:get {id} --json          # raw collector data (`--raw` is the same thing)
