Motion (Framer Motion) React animation library. Use for drag-and-drop, scroll animations, gestures, SVG morphing, or encountering bundle size, complex transitions, spring physics errors.

Design microservices architectures with service boundaries, event-driven communication, and resilience patterns. Use when building distributed systems, decomposing monoliths, or implementing microservices.

Manual-only skill for minimizing total codebase size. Only activate when explicitly requested by user. Measures success by final code amount, not effort. Bias toward deletion.

Behavioral guidelines to reduce common LLM coding mistakes. Use when writing, reviewing, or refactoring code to avoid overcomplication, make surgical changes, surface assumptions, and define verifiable success criteria.

Rowan is a cloud-native molecular modeling and medicinal-chemistry workflow platform with a Python API. Use for pKa and macropKa prediction, conformer and tautomer ensembles, docking and analogue docking, protein-ligand cofolding, MSA generation, molecular dynamics, permeability, descriptor workflows, and related small-molecule or protein modeling tasks. Ideal for programmatic batch screening, multi-step chemistry pipelines, and workflows that would otherwise require maintaining local HPC/GPU infrastructure.

This skill enables Claude to detect SQL injection vulnerabilities in code. It uses the sql-injection-detector plugin to analyze codebases, identify potential SQL injection flaws, and provide remediation guidance. Use this skill when the user asks to find SQL injection vulnerabilities, scan for SQL injection, or check code for SQL injection risks. The skill is triggered by phrases like "detect SQL injection", "scan for SQLi", or "check for SQL injection vulnerabilities".

This skill allows Claude to conduct comprehensive security audits of code, infrastructure, and configurations. It leverages various tools within the security-pro-pack plugin, including vulnerability scanning, compliance checking, cryptography review, and infrastructure security analysis. Use this skill when a user requests a "security audit," "vulnerability assessment," "compliance review," or any task involving identifying and mitigating security risks. It helps to ensure code and systems adhere to security best practices and compliance standards.

Spectral similarity and compound identification for metabolomics. Use for comparing mass spectra, computing similarity scores (cosine, modified cosine), and identifying unknown compounds from spectral libraries. Best for metabolite identification, spectral matching, library searching. For full LC-MS/MS proteomics pipelines use pyopenms.

Interact with Detail bugs for a repository via the CLI — list and filter bugs, inspect reports, close as resolved or dismissed, and reopen previously closed bugs.

Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always

Configure mutual TLS (mTLS) for zero-trust service-to-service communication. Use when implementing zero-trust networking, certificate management, or securing internal service communication.

Choose and implement Firecrawl architecture patterns for different scales and use cases. Use when designing new Firecrawl integrations, choosing between on-demand/scheduled/pipeline architectures, or planning scraping infrastructure. Trigger with phrases like "firecrawl architecture", "firecrawl blueprint", "how to structure firecrawl", "firecrawl at scale", "firecrawl pipeline design".

Implement Customer.io reliability and fault-tolerance patterns. Use when building circuit breakers, fallback queues, idempotency, or graceful degradation for Customer.io integrations. Trigger: "customer.io reliability", "customer.io resilience", "customer.io circuit breaker", "customer.io fault tolerance".

Execute use when detecting infrastructure drift from desired state. Trigger with phrases like "check for drift", "infrastructure drift detection", "compare actual vs desired state", or "detect configuration changes". Identifies discrepancies between current infrastructure and IaC definitions using terraform plan, cloudformation drift detection, or manual comparison.

Search code repositories for code related to a given code snippet, ranking results by call chain similarity, textual similarity, and functional similarity. Use when finding related code, locating similar implementations, discovering code dependencies, or identifying code that performs similar operations. Outputs ranked file lists with matching code snippets and relevance scores.

Migrate to LangChain from raw OpenAI SDK, LlamaIndex, or custom LLM code. Covers codebase assessment, side-by-side validation, RAG migration, agent migration, and feature-flagged gradual rollout. Trigger: "migrate to langchain", "langchain refactor", "legacy LLM migration", "replace openai SDK with langchain", "llamaindex to langchain".

Set up Instantly.ai API v2 authentication and project configuration. Use when creating a new Instantly integration, generating API keys, or configuring environment variables for the Instantly outreach platform. Trigger with phrases like "install instantly", "setup instantly", "instantly auth", "configure instantly API key", "instantly credentials".
