Pre-deployment security audit of Solidity smart contracts in a Foundry project.

Also enforces key hygiene (no plaintext private keys, encrypted cast keystore) and a secure deploy workflow. Use when writing, reviewing, testing, or deploying Solidity/Foundry contracts, building a dApp, or working with forge/cast/anvil, MetaMask, or Web3/DeFi code.

Neutrale moralisch-rechtliche Prüfinstanz für Politik und Entscheidungen — der lauffähige Prototyp des Forschungsprojekts "Die Position der Ungeborenen" (Schattenmodus Stufe 1). Nutze diesen Skill, wann immer eine politische Entscheidung, ein Gesetz(entwurf), eine Reform, ein Haushaltsbeschluss oder eine gesellschaftliche Streitfrage analysiert, geprüft oder begutachtet werden soll — auch bei Formulierungen wie "prüfe aus Sicht künftiger Generationen", "Gesetzespass", "was sagt das Grundgesetz dazu", "Superposition-Prüfung", "Gesetzesgeschichte/Containeranalyse", "Folgenabschätzung", "analysiere diese Reform", "lebende Verfassung" oder wenn der User eine Politik-Fragestellung mit Bitte um neutrale, mehrstufige Bewertung einbringt. Orchestriert die 5-CORE-Architektur (config.json): moralische Superposition-Instanz, Gesetzbuch-Verkörperungen, zweistufige Folgenabschätzung (retrospektiv/prospektiv mit Evidenzhierarchie), Wissens-Handler mit lokalem Speicher, einstellbarer Workflow.

Deep security audit for WordPress plugin/theme PHP code, covering issues beyond the basic sanitize/escape/nonce checklist — PHP object injection (unserialize), SSRF in remote requests, CSRF on state-changing GET handlers, mass assignment via $_POST loops, insecure file include / template injection, mail header injection, ZipSlip in archive extraction, type-juggling in auth comparisons, and TOCTOU race patterns in option/meta locks. Use after or alongside wp-security-audit when reviewing complex plugins, REST APIs, integrations that fetch remote URLs, file processors, or any code that handles uploads, archives, or self-rolled auth tokens.

Surfaces user-facing custom messages from a JetFormBuilder custom Form Action — both the idiomatic path (register message types via 'jet-form-builder/form-messages/register' so they appear in the form's Messages panel and can be overridden globally per form) and the action-local path (custom message fields inside the action editor, dispatched via Action_Exception for errors or via context + 'jet-form-builder/form-handler/after-send' + Messages_Manager::dynamic_success() for success messages). Use when a custom JFB action needs configurable messages for cases like "already subscribed", "duplicate row skipped", "API rate limited", or per-action success copy. Triggers on mentions of "JFB messages", "Action_Exception", "Base_Action_Messages", "jet-form-builder/form-messages/register", "_jf_messages", "dynamic_success", "add_context_once" with a message, "after-send" hook, or "custom action message".

Registers a custom JetFormBuilder Form Action — a server-side handler that runs after submit (send to API, subscribe to CRM, write to a sheet, etc.). Covers extending Base action class, declaring settings via action_attributes(), implementing do_action() with Action_Exception error reporting, building the action-editor React panel via window.JetFBActions.addAction(), the two field-mapping patterns (dynamic "Add row" like Google Sheets vs fixed-key pattern like Fluent CRM with predefined target fields), looking up the form's current fields via the useFields() hook, multi-select with FormLabeledTokenField, plus the category/docHref convention. Use when scaffolding a JFB integration plugin (Mailchimp, Slack, custom API, payment processor, CRM subscribe). Triggers on mentions of "JFB action", "jet-form-builder/actions/register", "Base_Action", "JetFBActions.addAction", "Action_Exception", "field map", or "fields_map".
