dev:log

dev:log is a skill for Claude Code from atournayre/claude-marketplace. It costs 14 tokens per session (767 once invoked), scanned A, original, MIT.

A workflow for adding structured logging to a PHP class. It checks for a logging interface and creates a method that returns useful object details, such as identifiers and statuses.

In plain words
What is it for?
Use it when a PHP class needs logging support, including reviewing its dependencies and selecting key properties to include in log output.
Why use it?
It avoids manually deciding how a class should expose information for logs. It also helps keep logged data consistent with the project's logging contracts.

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

dev:log 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 11d 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.

Ajout de logging avec LoggableInterface

Instructions à Exécuter

IMPORTANT : Exécute ce workflow étape par étape :

Fichier cible : $ARGUMENTS

Workflow

1. Lire et analyser le fichier

  • Lire le contenu du fichier PHP
  • Identifier la classe principale et ses propriétés
  • Vérifier si LoggableInterface est déjà implémentée

2. Chercher les dépendances LoggableInterface

Pour chaque type-hint de propriété ou paramètre :

  • Utiliser Grep pour chercher si la classe implémente LoggableInterface
  • Noter les classes qui l'implémentent pour appeler ->toLog() dessus

3. Ajouter LoggableInterface

Si la classe n'implémente pas encore LoggableInterface :

Ajouter l'import :

use Atournayre\Contracts\Log\LoggableInterface;

Ajouter l'interface à la déclaration de classe :

final class NomClasse implements LoggableInterface

Ajouter la méthode toLog() :

/**
 * @return array<string, mixed>
 */
public function toLog(): array
{
    return [
        // Propriétés clés de l'objet
    ];
}

4. Règles pour le contenu de toLog()

Propriétés à inclure :

  • id (si présent)
  • Identifiants métier (email, code, référence...)
  • États/statuts importants
  • Dates clés (createdAt, updatedAt...)

Propriétés à exclure :

  • Mots de passe, tokens, secrets
  • Données personnelles sensibles
  • Propriétés volumineuses (blobs, textes longs)

Pour les objets imbriqués :

  • Si l'objet implémente LoggableInterface : 'relation' => $this->relation->toLog()
  • Sinon : 'relationId' => $this->relation->getId() ou ignorer

Pour les collections :

/**
 * @return array{count: int, items: array<int, array<string, mixed>>}
 */
public function toLog(): array
{
    return [
        'count' => $this->count(),
        'items' => array_map(fn ($item) => $item->toLog(), $this->items),
    ];
}

5. Vérification PHPStan

  • Toujours ajouter @return array<string, mixed> sur la méthode
  • Pour les collections : utiliser le type array shape approprié

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.
