Handle user data, privacy, and GDPR compliance with Clerk. Use when implementing data export, user deletion, or privacy compliance features. Trigger with phrases like "clerk user data", "clerk GDPR", "clerk privacy", "clerk data export", "clerk delete user".

**REQUIRED** - Always activate FIRST on any git/VCS operations (commit, status, branch, push, etc.), especially when HEAD is detached. If `.jj/` exists -> this is a Jujutsu (jj) repo - raw git commands can corrupt data. Essential git safety instructions inside. DO NOT IGNORE.

React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.

AWS CloudFormation infrastructure as code for stack management. Use when writing templates, deploying stacks, managing drift, troubleshooting deployments, or organizing infrastructure with nested stacks.

Generates secure Aptos Move V2 smart contracts with Object model, Digital Asset integration, security patterns, and storage type guidance. Includes comprehensive storage decision framework for optimal data structure selection. Triggers on: 'write contract', 'create NFT collection', 'build marketplace', 'implement minting', 'generate Move module', 'create token contract', 'build DAO', 'implement staking'. Ask storage questions when: 'store', 'track', 'registry', 'mapping', 'list', 'collection'.

Store, verify, and manage AI data on the Ethereum blockchain (Base network) using the ERCData standard. Use when an agent needs to store data fingerprints on-chain, verify data integrity, create audit trails, manage access control for private data, or interact with the ERCData smart contract. Supports public and private storage, EIP-712 verification, snapshots, and batch operations.

Answer questions about live production system behavior — current variable values, execution durations, hit counts, and value distributions — by instrumenting running services with Lightrun MCP tools. Use when the question requires live runtime data rather than static code analysis (e.g. "show recent requests to this endpoint", "show the runtime distribution for this operation", "what values appear for this expression in production?", "which branch runs for customer X?").

Ensures alignment between user and Claude during feature/spec planning through a structured interview process. Use this skill when the user invokes /plan-interview before implementing a new feature, refactoring, or any non-trivial implementation task. The skill runs an upfront interview to gather requirements across technical constraints, scope boundaries, risk tolerance, and success criteria before any codebase exploration. Do NOT use this skill for: pure research/exploration tasks, simple bug fixes, or when the user just wants standard planning without the interview process.

Plan, create, and improve Linear issues with business-level clarity. Use this skill whenever the user wants to create a Linear issue, improve an existing one, file a bug, plan a feature, create a chore/enabler, or mentions "linear issue", "file an issue", "create a ticket", "log a bug", "new issue", "plan this work", "improve this issue", or "clean up this ticket". Also trigger when the user says "I found a bug", "we need a ticket for...", "can you create an issue for...", "break this down into issues", or pastes a Linear issue URL/ID. This is the required way to create and maintain issues — it ensures every issue follows the team's format and is scoped for small PRs.

Detect flaky tests from CI history and propose LLM-validated fixes via quarantine pull requests. Use to find flaky tests, analyze CI test stability, identify tests that flip pass/fail without code changes, or set up automated quarantine workflows. Supports any test framework that emits JUnit XML (pytest, unittest, JUnit, TestNG, Vitest, Jest with junit reporter). Trigger when users mention "flaky tests", "intermittent failures", "tests that randomly fail", "quarantine flaky tests", "CI flakiness", or ask to "find unreliable tests", "analyze CI history", "mark tests as flaky".

Guides snapshot mode selection, capture workflows, QA sharing, and team setup for Jahro Snapshots. Use when the user mentions snapshots, bug capture, sharing logs, streaming, recording, QA workflow, team collaboration, or wants to share debugging sessions with their team.

Migrate to Juicebox from other tools. Trigger: "switch to juicebox", "migrate to juicebox".

Upgrade Evernote SDK versions and migrate between API versions. Use when upgrading SDK, handling breaking changes, or migrating to newer API patterns. Trigger with phrases like "upgrade evernote sdk", "evernote migration", "update evernote", "evernote breaking changes".

Diagnose and resolve common Documenso API errors and issues. Use when encountering Documenso errors, debugging integration issues, or troubleshooting failed operations. Trigger with phrases like "documenso error", "documenso 401", "documenso failed", "fix documenso", "documenso not working".

Plan and execute Deepgram SDK upgrades and model migrations. Use when upgrading SDK versions (v3 to v4 to v5), migrating models (Nova-2 to Nova-3), or planning API version transitions. Trigger: "upgrade deepgram", "deepgram migration", "update deepgram SDK", "deepgram version upgrade", "nova-3 migration".

Manage PostHog feature flags, cohorts, dashboards, and insights via the `piglet` CLI. Use when the user needs to list, create, update, or delete PostHog resources, check flag status, manage rollouts, or export configuration.
