# Send Deno to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### When to Use

User needs Deno expertise — secure TypeScript runtime with permissions model. Agent handles permission configuration, dependency management via URLs/npm, and migration from Node.js.

### Quick Reference

TopicFilePermission systempermissions.mdImports and dependenciesimports.mdNode.js migrationnode-compat.md

### Permission Traps

--allow-all in development — then production crashes because you don't know what permissions you actually need
--allow-read without path — grants access to entire filesystem, security hole
--allow-run without list — subprocess can run anything, specify: --allow-run=git,npm
--allow-env without list — leaks all env vars, specify: --allow-env=API_KEY,DATABASE_URL
--allow-net without list — can connect anywhere, specify hosts: --allow-net=api.example.com
Missing permission in CI — hangs waiting for prompt that never comes, add --no-prompt

### Import Traps

Remote URLs in production — network failure = app won't start, vendor dependencies locally
No lockfile by default — deps can change between runs, always use deno.lock
@^1.0.0 semver syntax doesn't exist — use exact URLs or import maps
Import maps in wrong place — must be in deno.json, not separate file (Deno 2.x)
HTTPS required — HTTP imports blocked by default, most CDNs work but self-hosted may not
URL typo — no error until runtime when import fails

### TypeScript Traps

.ts extension required in imports — model generates extensionless imports that fail
tsconfig.json paths ignored — Deno uses import maps in deno.json, not tsconfig
Type-only imports — must use import type or bundler may fail
Decorators — experimental, different from tsc behavior
/// <reference> — handled differently than tsc, may be ignored

### Deployment Traps

deno compile includes runtime — binary is 50MB+ minimum
--cached-only requires prior cache — fresh server needs deno cache first
Deno Deploy limitations — no filesystem, no subprocess, no FFI
Environment variables — different API: Deno.env.get("VAR") not process.env.VAR
Signals — Deno.addSignalListener not process.on("SIGTERM")

### Testing Traps

Deno.test different from Jest — no describe, different assertions
Async test without await — test passes before promise resolves
Resource leaks — tests fail if you don't close files/connections
Permissions in tests — test may need different permissions than main code
Snapshot testing — format differs from Jest snapshots

### npm Compatibility Traps

npm: specifier — works for most packages but native addons fail
node: specifier required — import fs from 'fs' fails, need import fs from 'node:fs'
node_modules optional — enable with "nodeModulesDir": true in deno.json
package.json scripts — not automatically supported, use deno.json tasks
Peer dependencies — handled differently, may get wrong versions

### Runtime Differences

Deno.readTextFile vs fs.readFile — different API, different error types
fetch is global — no import needed, unlike Node 18-
Top-level await — works everywhere, no wrapper needed
Permissions at runtime — can request dynamically but user must approve
