Honest about tooltip-spam (visual noise that users develop blindness to), one-and-done (help invisible at the moment of need), and contextual-when-needed (surfaces help at the moment friction occurs) patterns. Triggers on product tour, in-product tooltip, contextual help, walkthrough, feature tour, hint system, in-app guidance, tour platform.

Use when: protecting forms, securing login/signup, preventing spam, migrating from reCAPTCHA, integrating with React/Next.js/Hono, implementing E2E tests, or debugging CSP errors, token validation failures, Chrome/Edge first-load issues, multiple widget rendering bugs, timeout-or-duplicate errors, or error codes 100*/106010/300*/600*.
Expert cold email strategist for B2B outbound campaigns. Use when the user asks about cold email writing, email sequences, email deliverability, domain warmup, SPF/DKIM/DMARC setup, email personalization, cold email templates, email copywriting frameworks, email compliance (CAN-SPAM, GDPR), bounce management, inbox placement, email infrastructure, sequencing tools (Instantly, Smartlead, Lemlist), or cold outreach strategy. Also triggers on "cold email", "email sequence", "deliverability", "warmup", "SPF", "DKIM", "DMARC", "bounce rate", "spam", "inbox placement", "email template", "follow-up email", "outbound email", "Instantly", "Smartlead", "email copy", "subject line", "personalization". Do NOT use for marketing emails or newsletters.
Implement rate limiting to prevent brute force attacks, spam, and resource abuse. Use this skill when you need to protect endpoints from automated attacks, prevent API abuse, limit request frequency, or control infrastructure costs. Triggers include "rate limiting", "rate limit", "brute force", "prevent spam", "API abuse", "resource exhaustion", "DoS", "withRateLimit", "too many requests", "429 error".
Receive and process Postmark webhooks. Use when setting up Postmark webhook handlers, handling email delivery events, processing bounces, opens, clicks, spam complaints, or subscription changes.
Trigger this skill when the user wants to collect structured data, create forms, or set up submission endpoints. Covers any form type (contact, feedback, signup, waitlist, bug report, support, lead capture, surveys, applications) and any collection method (HTML forms, scripts, AI agents). Also trigger for managing existing forms or submissions, generating frontend form integration code, setting up webhooks or Discord/Slack notifications, configuring spam protection or AI features (translation, smart replies), connecting MCP for AI-assisted form management, or anything referencing Postbox or usepostbox.com. If the user needs data flowing in from anywhere, this skill applies.
