What it does
Nix Haskell is an agent skill from srid/emanote. Use this when working on a Haskell project with Nix. Covers haskell-flake setup, adding/overriding dependencies, package settings, and devShell configuration.
Its SKILL.md is about 330 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Emanate a structured view of your plain-text notes.
Example prompts
- “/nix-haskell”
What it can do on your machine
Read from SKILL.md and the folder at commit 9d01037. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
github.com
Also links to:
nixos-unified.orgcommunity.flake.partsflake.parts
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Nix Haskell loads about 327 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 106 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 106 words (~327 tokens).
“Use haskell-flake — a flake-parts module. Start from haskell-template. Requires a .cabal or cabal.project file; haskell-flake scans for it automatically.”

Questions about Nix Haskell
What does Nix Haskell do?
Use this when working on a Haskell project with Nix. An agent skill from srid/emanote. Nix Haskell is an agent skill from srid/emanote. Use this when working on a Haskell project with Nix.
How do I install Nix Haskell in Claude Code?
Run `npx skills add srid/emanote --skill nix-haskell -a claude-code`. Or copy the skill folder (.agents/skills/nix-haskell in srid/emanote) into .claude/skills/nix-haskell in your project. Claude Code loads it when a task matches its description.
How do I install Nix Haskell in Codex?
Run `npx skills add srid/emanote --skill nix-haskell -a codex`. Or copy the skill folder (.agents/skills/nix-haskell in srid/emanote) into .agents/skills/nix-haskell in your project. Codex loads it when a task matches its description.
Can I use Nix Haskell in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add srid/emanote --skill nix-haskell -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/nix-haskell, .gemini/skills/nix-haskell, .github/skills/nix-haskell and .opencode/skills/nix-haskell in your project.
What does Nix Haskell need to run?
Going by SKILL.md and its folder, Nix Haskell needs the command-line tools its instructions call (git).
Does Nix Haskell access the network?
SKILL.md names 4 domains. In commands or code: github.com; the agent is likely to contact it when it follows the instructions. As links in the text: nixos-unified.org, community.flake.parts and flake.parts. This is read from the text; nothing was executed.
Is Nix Haskell safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Nix Haskell use?
Nix Haskell has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Nix Haskell use?
About 327 tokens (SKILL.md is roughly 1.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Nix Haskell?
Skills that share tags, products or a category with Nix Haskell: Devcontainers Nix (sickn33/agentic-awesome-skills, 47k stars), Haskell Pro (davila7/claude-code-templates, 32k stars), Nix (r17x/universe, 151 stars) and Nix Config Debug (ryan4yin/nix-config, 2.1k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Nix Haskell?
srid (a GitHub user) maintains it in srid/emanote, which has 963 GitHub stars. The repository holds 25 skills in this directory. The repository was last updated on July 26, 2026.
