  • Development commands: deno fmt, deno lint, deno task check, deno task build
  • CI: GitHub Actions workflow (.github/workflows/deno.yaml)

Intentionally lean to maximize information density and scannability.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• dl.deno.land
  • Triggering command: curl -s REDACTED (dns block)
• jsr.io
  • Triggering command: deno lint (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Review the project structure, and add a lean AGENTS.md describing repo layout, tools, pre-commit checks and relations to liked projects such as pup-telemetry etc.
