drupal-debugging

A collection of Drupal debugging commands for Drush, Drupal’s command-line tool. It covers services, content entities, cache, configuration, logs, database queries, and PHP evaluation.

In plain words
What is it for?
Use it to view watchdog logs, clear selected caches, inspect configuration, check site status, query the database, and examine Drupal state.
Why use it?
It gives developers direct ways to inspect a Drupal site when diagnosing errors or unexpected behaviour. This reduces guesswork during troubleshooting.

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.

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 D, and why

drupal-debugging scanned grade D with 2 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

| Browser screenshots not saving | `ssh web mkdir -p /var/www/html/sites/simpletest/browser_output && ssh web chmod 777 /var/www/html/sites/simpletest/browser_output` |

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

How it starts

The opening of the file, as written. The whole thing — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Environment

All commands via ssh web. For Xdebug tracing/profiling (function call trees, execution timing), use the xdebug-profiling skill.

Core Debugging & Information

Command Purpose
ssh web drush status Drupal root, site path, DB connection
ssh web drush core-status Detailed system status
ssh web drush watchdog:show Recent log messages
ssh web drush watchdog:show --severity=Error Only errors
ssh web drush watchdog:show --count=50 Last 50 entries

Cache Debugging

Command Purpose
ssh web drush cache:clear render Clear only render cache
ssh web drush cache:clear router Rebuild routing cache
ssh web drush cache:clear css-js Clear CSS/JS aggregation cache
ssh web drush cr Full cache rebuild (when in doubt, use this)

Configuration Debugging

Command Purpose
ssh web drush config:get system.site Show config value
ssh web drush config:set system.site name "New" Set config value
ssh web drush config:status Show config sync status

PHP Evaluation (drush php:eval)

# Inspect state values
ssh web drush php:eval "var_dump(\Drupal::state()->get('system.cron_last'));"

# Check if function exists
ssh web drush php:eval "var_dump(function_exists('my_custom_function'));"

# List enabled modules
ssh web drush php:eval "print_r(array_keys(\Drupal::moduleHandler()->getModuleList()));"

# Pending entity definition updates
ssh web drush php:eval "print_r(\Drupal::entityDefinitionUpdateManager()->getChangeSummary());"

# List available services
ssh web drush php:eval "print_r(\Drupal::getContainer()->getServiceIds());"

# Check specific service exists
ssh web drush php:eval "var_dump(\Drupal::hasService('mymodule.my_service'));"

# Inspect entity field definitions
ssh web drush php:eval "print_r(array_keys(\Drupal::service('entity_field.manager')->getFieldDefinitions('node', 'article')));"

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.

drupal-debugging is a skill published in the GitHub repository trebormc/drupal-ai-agents (10 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 115 tokens to every session and 2,193 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it D with 2 findings (asks for root, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
