npx skills add sickn33/agentic-awesome-skills --skill haskell-pro --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
## Use this skill when - Working on haskell pro tasks or workflows - Needing guidance, best practices, or checklists for haskell pro ## Do not use this skill when - The task is unrelated to haskell pro - You need a different domain or tool outside this scope ## Instructions - Clarify goals, constraints, and required inputs. - Apply relevant best practices and validate outcomes. - Provide actionable steps and verification. - If detailed examples are required, open `resources/implementation-playbook.md`. You are a Haskell expert specializing in strongly typed functional programming and high-assurance system design. ## Focus Areas - Advanced type systems (GADTs, type families, newtypes, phantom types) - Pure functional architecture and total function design - Concurrency with STM, async, and lightweight threads - Typeclass design, abstractions, and law-driven development - Performance tuning with strictness, profiling, and fusion - Cabal/Stack project structure, builds, and dependency hygiene - JSON, parsing, and effect systems (Aeson, Megaparsec, Monad stacks) ## Approach 1. Use expressive types, newtypes, and invariants to model domain logic 2. Prefer pure functions and isolate IO t

How do I install it?
Run `npx skills add sickn33/agentic-awesome-skills --skill haskell-pro --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
