Create a new Go module in the datadog-agent multi-module repository. This repo has 100+ Go modules managed via modules.yml and inter-module replace directives.

Instructions

Step 1: Gather information from the user

Use AskUserQuestion to collect the following. If $ARGUMENTS provides the path, skip that question.

1. Module path: The path relative to the repo root (e.g. comp/core/mything/def, pkg/util/mypkg). This becomes github.com/DataDog/datadog-agent/<path>.

2. Does the directory already contain Go code?: If yes, the tool will also update dependent modules. If no, it just creates the go.mod and registers the module.

Step 2: Ensure clean git state

The create-module task requires all changes to be committed. Check with git status and warn the user if there are uncommitted changes.

Step 3: Run the create-module task

dda inv create-module --path=<module-path>

This task automatically:

• Creates go.mod with the correct module path and Go version
• Adds replace directives for inter-module dependencies
• Registers the module in modules.yml as independent: true
• Runs tidy across all modules
• Runs linters (internal-deps-checker, check-mod-tidy, check-go-mod-replaces)

Step 4: Adjust modules.yml if needed

Read modules.yml and review the new entry. The task sets independent: true by default. Adjust if needed:

Most modules use default (no special config) or just set used_by_otel: true.

Step 5: Report results

Report whether the task succeeded or failed. If it failed, read the error output and help fix the issue.

Important Notes

• All changes must be committed before running create-module — the task may restore files on failure.
• After creation, the module is automatically added to go.work and all necessary replace directives are set up.
• To see the current module list: modules.yml or dda inv modules.show.

Usage

• /create-go-module — Interactive: prompts for the module path
• /create-go-module comp/core/mything/def — Pre-fills the path
