Modern Deno development knowledge for AI coding assistants. These skills teach
your AI assistant how to build Deno applications using current best practices.
deno-guidance, deno-expert, and deno-project-templates have been merged
into the single deno skill. Their content overlapped heavily, and project
scaffolding is now handled by deno init rather than by pasted templates. If
you installed any of the three individually, install deno instead.
Deno works like npm and bun - deno install reads package.json,
deno add express installs from npm, node_modules and node: built-ins
work. Migration is not a rewrite.
npm and JSR both work - use whichever has the package you need; JSR is a
good default for new Deno-first code and the standard library (@std/*).
Built-in tools - deno fmt, deno lint, deno test, deno check
replace prettier, eslint, jest, and tsc with no dependencies.
Permissions are the real difference - prefer scoped grants like
--allow-net=example.com over -A.
# Step 1: Add the marketplace/plugin marketplace add denoland/skills# Step 2: Install the plugin/plugin install deno-skills@denoland-skills
Option 2: npx skills
Works across Claude Code, Cursor, Copilot, and other skills-compatible agents:
bash
# All skillsnpx skills add denoland/skills# Or just onenpx skills add denoland/skills --skill deno
Option 3: Manual installation
Copy the skills you want to use:
bash
# Clone the repositorygit clone https://github.com/denoland/skills.git /tmp/deno-skills# Copy individual skills to your personal skills directorycp -r /tmp/deno-skills/skills/deno ~/.claude/skills/cp -r /tmp/deno-skills/skills/deno-deploy ~/.claude/skills/# ... or copy all skillscp -r /tmp/deno-skills/skills/* ~/.claude/skills/# Or for project-specific installationcp -r /tmp/deno-skills/skills/* .claude/skills/
Note: Agent Skills in Cursor are currently only available in v2.4+.
bash
# Clone the repositorygit clone https://github.com/denoland/skills.git /tmp/deno-skills# Copy skills to your Cursor skills directorycp -r /tmp/deno-skills/skills/* ~/.cursor/skills/# Or for project-specific installationcp -r /tmp/deno-skills/skills/* .cursor/skills/
Note: Agent Skills require the chat.useAgentSkills setting to be enabled
(currently in preview).
bash
# Clone the repositorygit clone https://github.com/denoland/skills.git /tmp/deno-skills# Copy skills to your project's skills directorymkdir -p .github/skillscp -r /tmp/deno-skills/skills/* .github/skills/# Or for personal installationcp -r /tmp/deno-skills/skills/* ~/.copilot/skills/
For other AI coding assistants that support the Agent Skills specification, copy
the skill directories from skills/ to your platform’s skills directory. Check
your platform’s documentation for the correct location.

Discovery
5 skills found by walking the repository tree for SKILL.md, not by matching a directory convention. One layout observed: skills/*/SKILL.md.
Issue colours
Resolved from a deterministic hash of the owner name. Two accent tones are generated per issue and each is proven against its own ground before it ships: a single accent that passes AA on both light and dark paper is arithmetically impossible.
Heading repairs
1 repair applied to the front matter so the document has one h1 and no skipped levels:
Shifted “16 headings” from h1 to h2 so the skill title is the only h1.
Images inside a skill come from the upstream repository. Where the author gave no alternative text we mark the image decorative rather than inventing a description — a plausible caption we made up is worse than none for the reader who depends on it.
Marketplace
A plugin manifest is published at .claude-plugin/marketplace.json by Deno Land, declaring 1 plugin. It is read for editorial metadata only — never as the skill index, which is always the repository tree.
Signal
Install counts come from skills.sh. They measure downloads, not quality, and an unranked repository is not an unread one.
Agent surfaces
The whole issue is available as one markdown document at /denoland/skills.md, and each skill at its own .md URL.
Publication
Set by Skills Docs from the source repository. Body text is Literata at the reader’s chosen size and measure; code is Geist Mono. Nothing on this page was written by us except this paragraph.
