Guideline for designing, implementing, and verifying secure APIs following OWASP API Security Top 10 (2023) best practices. Use when the user wants to: (1) review API code or design for security vulnerabilities, (2) design a secure REST, GraphQL, or gRPC API architecture, (3) implement API authentication and authorization (OAuth2, JWT, API keys, mTLS), (4) configure rate limiting, input validation, or CORS, (5) audit API endpoints for BOLA, BFLA, or mass assignment vulnerabilities, (6) create API security checklists or verification plans, (7) fix API security bugs or harden existing APIs, (8) set up API security testing (OWASP ZAP, Schemathesis, Burp Suite), or (9) handle any API security concern including SSRF prevention, resource consumption limits, business flow protection, API inventory management, and secure third-party API consumption.
Recover a suppressed, blocked, or deactivated Amazon listing. Maps the suppression reason code to the specific fix path and produces the reinstatement message. Use when a user asks about a suppressed listing, a blocked listing, listing deactivated, pricing error suppression, image policy, restricted phrase, or missing required field. Trigger phrases: "suppressed listing", "blocked listing", "listing deactivated", "pricing error", "image suppression", "restricted phrase". Works with zero tools. the user pastes the suppression notice.
Check an Amazon product for compliance and safety requirements before and after listing. Covers required certifications, labeling and warning requirements, restricted-substance rules, documentation Amazon may demand, and category-specific safety rules. Use when a user asks about product compliance, safety requirements, certifications, required labels or warnings, a compliance document request from Amazon, or whether a product is allowed. Trigger phrases: "product compliance", "safety requirements", "certifications", "compliance documents", "required labels", "is this product allowed". Works with zero tools.
Generate and EDIT images with OpenAI gpt-image-2 via AceDataCloud API. Use when you need high-fidelity images from a prompt, or to edit/composite existing images (e.g. fuse a real logo/QR/screenshot into a scene, keep characters consistent, restyle). Strong at legible text and faithful editing.
Publish, delete and read your own posts (toots) on any Mastodon instance via the Mastodon REST API. Use when the user wants to post a toot to their Mastodon / fediverse account, cross-post an article as a short dev-focused post, delete a toot, or list their own recent posts with engagement stats (boosts, favourites, replies).
Apply, switch, and restore Codex desktop themes from the local ~/.codexthemes library with one command, and report which theme is currently active. Use when a user asks to apply or activate a theme they created or installed, switch between installed themes, restore the native Codex look, or check or debug which theme is currently applied.
High-performance vector similarity search engine for RAG and semantic search. Use when building production RAG systems requiring fast nearest neighbor search, hybrid search with filtering, or scalable vector storage with Rust-powered performance.
Primary Python tool for 40+ bioinformatics services. Preferred for multi-database workflows: UniProt, KEGG, ChEMBL, PubChem, Reactome, QuickGO. Unified API for queries, ID mapping, pathway analysis. For direct REST control, use individual database skills (uniprot-database, kegg-database).
This skill should be used when the user asks to "design REST APIs", "optimize database queries", "implement authentication", "build microservices", "review backend code", "set up GraphQL", "handle database migrations", or "load test APIs". Use for Node.js/Express/Fastify development, PostgreSQL optimization, API security, and backend architecture patterns.

Python backend development expertise for FastAPI, security patterns, database operations, Upstash integrations, and code quality. Use when: (1) Building REST APIs with FastAPI, (2) Implementing JWT/OAuth2 authentication, (3) Setting up SQLAlchemy/async databases, (4) Integrating Redis/Upstash caching, (5) Refactoring AI-generated Python code (deslopification), (6) Designing API patterns, or (7) Optimizing backend performance.
Financial data from Yahoo Finance: stock/bond prices, credit analysis, macro dashboard, FX rates, ETF flows, fundamentals, and news.
