Linear — Issue & Project Management
Linear is eating Jira's lunch, and Claude needs to speak its language. This helper handles the full workflow: creating issues from plain English, updating status mid-conversation, querying project backlogs, and syncing team context without tab-switching. Real use case: you're in a Claude conversation planning a feature. You mention a blocker. The helper creates the Linear issue, assigns it, links dependencies, and moves on. No context loss. No manual data entry. You stay in flow.
Codex Collab — Second-Opinion Architecture
Claude is confident. Sometimes that's dangerous. This skill invokes Codex—an independent LLM perspective—on demand or proactively when the stakes are high: code review decisions, system architecture, design trade-offs. You propose a database migration strategy. Codex pokes holes. Claude refines. You get both consensus and conflict-testing without leaving the conversation. Shipping decisions that survive scrutiny.
Social Autoposter — Multi-Platform Threading
Reddit, X, LinkedIn, Bluesky—one command, multiple platforms. This skill finds relevant threads, composes platform-specific variants of your message, posts, and tracks engagement. Founder use case: you ship a feature. One instruction: "post this launch to social, find 10 threads where this helps, comment thoughtfully." The helper handles voice consistency across platforms and reports back on reach. Your network grows while you sleep.
Russian Text Quality — Typography & Grammar
Language-specific polish matters. This skill applies professional Russian typography, grammar, and style rules that non-native speakers miss: hyphenation rules, quotation conventions, verb aspect consistency. If you're building products for Russian-speaking markets or translating content, this catches what spell-check won't. One less review cycle before publish.
PICT Test Designer — Combinatorial Test Generation
Writing test cases manually is combinatorial hell. Pairwise Independent Combinatorial Testing solves it algorithmically. Feed this helper your requirements or code. It extracts parameters, defines constraints, generates test matrices that hit all meaningful combinations with minimal case bloat. QA teams use this to cut test case count by 80% while keeping coverage tight.
We're 950 skills in. The marketplace works because each one solves a specific, repeatable problem. No bloat. No compromise.
