scraper: Instructions file for Codex

AGENTS.md

scraper AGENTS.md is an instructions file for Codex, OpenCode from rem42/scraper. It costs 1,445 tokens per session, scanned A, original, MIT.

Project instructions for a PHP library that turns defined web requests into typed result objects. Web scraping means collecting information from websites automatically.

In plain words
What is it for?
Use them when adding or changing scraper requests, HTTP handling, API result classes, or PHP namespaces.
Why use it?
They explain the library's required class names, annotations, request options, and response-parsing structure so changes fit the existing design.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md; built for aider.

This is rem42/scraper's own configuration. It tells Codex and OpenCode how to work on scraper itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything scraper configures →

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

scraper AGENTS.md 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 1mo 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.

AGENTS.md

But et vue d'ensemble

Ce package fournit un petit framework de "scraper" réutilisable :

  • Définition d'une requête (classe Request) annotée par l'attribut #[Scraper(...)].
  • Un Client qui transforme la Request en appel HTTP (via un HttpClientInterface injecté), puis instancie la classe Api correspondante pour parser la réponse.

Points d'entrée importants

  • src/Client.php — méthode principale : Client::send(ScraperRequest $request).
    • construit les options HTTP à partir des interfaces implémentées par la Request (headers, query, body, json, auth). Voir buildOptions().
    • récupère l'attribut Scraper via ExtractAttribute::extract() et appelle le endpoint.
    • instancie la classe Api correspondante en remplaçant "Request" par "Api" dans le nom de classe (voir getApiReflectionClass()).

Patterns et conventions spécifiques

  • PSR-4 autoload: namespace racine Scraper\Scraper\ -> src/ (voir composer.json autoload).
  • Naming convention Request->Api : si vous créez FooRequest, fournissez FooApi (extends Api\AbstractApi) — le Client s'en sert automatiquement.
  • Attributs PHP: les Requests sont annotées par #[Scraper(...)] (voir src/Attribute/Scraper.php) : contient method, scheme, host, path.
  • Variable substitution dans path: {name} est remplacé par l'appel getName() sur l'objet Request (voir src/Attribute/ExtractAttribute.php).
  • Options HTTP: implémentez les interfaces de src/Request/ pour activer les options automatiques :
    • RequestHeaders -> getHeaders() → option headers
    • RequestQuery -> getQuery() → option query
    • RequestBody / RequestBodyJson -> getBody() / getJson() → option body / json
    • RequestAuthBearer / RequestAuthBasic -> getBearer() / getAuthBasic() → auth_bearer / auth_basic

Composants clés (exemples)

  • src/Client.php — orchestrateur principal, error handling et mapping Request->Api.
  • src/Attribute/ExtractAttribute.php — lit les attributs #[Scraper], fusionne héritages et remplace les variables dans path.
  • src/Factory/SerializerFactory.php — création du Serializer Symfony utilisé par les API pour dénormaliser les réponses.
  • src/Request/ScraperRequest.php — classe de base pour les Requests (ssl, auth basic helpers).

Dépendances et intégrations

  • Dépendances runtime (extraites de composer.json):
    • symfony/http-client-contracts (injection HttpClientInterface)
    • symfony/serializer-pack (Serializer + normalizers)
  • Extensions suggérées: ext-json, ext-simplexml, ext-soap (voir suggest dans composer.json).

Flux d'exécution succinct

  1. L'utilisateur instancie une Request (ex: new FooRequest()), éventuellement configure headers/query/body.
  2. Client::send($request) → ExtractAttribute::extract($request) pour construire URL/méthode.
  3. HttpClientInterface->request(...) est appelé avec les options produites par buildOptions().
  4. Une classe FooApi (remplacement Request->Api) est instanciée et sa méthode execute() est retournée.

Workflows dev (build / test / QA)

  • Tests unitaires: depuis la racine du package ou du monorepo, lancer:
composer run unit-test
# ou
./vendor/bin/phpunit -c packages/scraper/phpunit.xml
  • Analyse statique: composer run static-analysis (phpstan) — configuration : ./vendor/bin/phpstan analyse src --level=max.
  • Format / style: composer run code-style-check et composer run code-style-fix (php-cs-fixer).

Conseils pratiques pour les agents/automates

  • Pour ajouter un nouveau scraper pour un site :
    1. Créer src/Request/MySiteRequest.php extends ScraperRequest et ajoutez les getters utilisés par {...} dans le path.
    2. Annoter la classe par #[Scraper(method: Method::GET, scheme: Scheme::HTTPS, host: 'example.com', path: '/foo/{id}')].
    3. Créer src/Api/MySiteApi.php extends Api\AbstractApi et implémenter execute(): object|array|bool|string pour parser ResponseInterface via $this->serializer.

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.
