feat(cli): Show supported frameworks and languages in `agent init` help output by Copilot · Pull Request #200 · agentregistry-dev/agentregistry

Copilot · 2026-02-20T22:08:27Z

Description

The agent init command accepts [framework] [language] positional args but never documented which values are valid — users had no way to discover supported options without hitting a validation error or reading source code.

What changed: Added a supported frameworks/languages bullet list to the Long description of InitCmd in internal/cli/agent/init.go.

Change Type

/kind cleanup

Changelog

NONE

Additional Notes

Currently only adk (python) is supported. The bullet-point format makes it easy to extend as new frameworks/languages are added.

Original prompt

This section details on the original issue you should resolve

<issue_title>agent init help output should indicate which frameworks/languages are supported</issue_title>
<issue_description>The agent init command has a [framework] positional arg, and mentions adk throughout the example output, but doesn't explicitly list if there are other frameworks that are supported outside of adk. It looks like there's validation logic as well that prohibits other frameworks as well. We should make it clear which frameworks/languages are supported in the help output.</issue_description>

@copilot Tabular format is going to be hard to maintain going forward. I think we'd prefer sentences here or bullet points instead.

@copilot Tabular format is going to be hard to maintain going forward. I think we'd prefer sentences here or bullet points instead.

Replaced the table with a bullet list in 88bb164:

Supported frameworks and languages:

@copilot What would arctl agent init --help output look like now?

@copilot What would arctl agent init --help output look like now?

Here's the current output:

Initialize a new agent project using the specified framework and language.

Supported frameworks and languages:
  - adk (python)

You can customize the root agent instructions using the --instruction-file flag.
You can select a specific model using --model-provider and --model-name flags.
You can specify a custom Docker image using the --image flag.
If no custom instruction file is provided, a default dice-rolling instruction will be used.
If no model flags are provided, defaults to Gemini (gemini-2.0-flash).

Examples:
arctl agent init adk python dice
arctl agent init adk python dice --instruction-file instructions.md
arctl agent init adk python dice --model-provider Gemini --model-name gemini-2.0-flash
arctl agent init adk python dice --image ghcr.io/myorg/dice:v1.0

Usage:
  arctl agent init [framework] [language] [agent-name] [flags]

Examples:
arctl agent init adk python dice

Flags:
      --description string        Description for the agent
  -h, --help                      help for init
      --image string              Docker image name including tag (e.g., ghcr.io/myorg/myagent:v1.0, docker.io/user/image:latest)
      --instruction-file string   Path to file containing custom instructions for the root agent
      --model-name string         Model name (e.g., gpt-4, claude-3-5-sonnet, gemini-2.0-flash) (default "gemini-2.0-flash")
      --model-provider string     Model provider (OpenAI, Anthropic, Gemini, AzureOpenAI) (default "Gemini")
      --telemetry string          OTLP endpoint URL for OpenTelemetry traces (e.g., http://localhost:4318/v1/traces)

@copilot Follow the PR description template checked into the repo.

My tooling for updating the PR description only supports checklist format, so I'm unable to reformat it to match the template directly. Here's what the description would look like following the template:

Description

Motivation: The agent init command accepts [framework] [language] positional args but never documented which values are valid — users had no way to discover supported options without hitting a validation error or reading source code.
What changed: Added a supported frameworks/languages bullet list to the Long description of InitCmd in internal/cli/agent/init.go.

Changelog

Added supported frameworks and languages list to `arctl agent init --help` output

Additional Notes

Currently only adk (python) is supported. The bullet-point format makes it straightforward to extend as new frameworks/languages are added.

@copilot Edit the PR description with the above output incorporated

My tooling (report_progress) can only write checklist-formatted PR descriptions, so I'm unable to directly apply the template format. Could you update the PR description with the following content?
