Foundational Haskell patterns and core language features for pure functional programming. This skill serves as both a reference for common patterns and foundation for advanced Haskell development.
Lang Haskell Dev is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/lang-haskell-dev/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when writing Haskell code, understanding pure functions, working with Maybe/Either, leveraging the type system, or needing guidance on functional programming patterns. This is the entry point for Haskell development.
The Lang Haskell Dev Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 146,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
mkdir -p ~/.claude/skills/lang-haskell-dev curl -L https://claudskills.com/skills/lang-haskell-dev/SKILL.md \ -o ~/.claude/skills/lang-haskell-dev/SKILL.md
Or just download SKILL.md directly and drop it into ~/.claude/skills/lang-haskell-dev/. Claude Code auto-discovers it on next session.
Skills live at ~/.claude/skills/lang-haskell-dev/SKILL.md on macOS/Linux, or %USERPROFILE%\.claude\skills\lang-haskell-dev\SKILL.md on Windows. See the full install guide for step-by-step instructions.
Open @claudskills_bot on Telegram, tap Open Desktop App, and the desktop app installs this skill for you. Or share the bot link with a colleague — they get the same one-tap install. Learn more →
The ClaudSkills desktop app installs any skill directly into ~/.claude/skills/ with one click — no terminal required. Pro starts at $9/mo or $149 lifetime.
For the full experience including quality scoring and one-click install features for each skill — upgrade to Pro.
SKILL.md from the source repository to ~/.claude/skills/lang-haskell-dev/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Lang Haskell Dev is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category.
