About dagger-codegen

dagger-codegen is a skill for Dagger developers working on code generation. It distinguishes four codegen paths and points to relevant Go templates, SDK interfaces, and reference files.

Key features

01Distinguishes four Dagger codegen paths
02Locates Go templates and SDK interfaces
03Points to generated client implementation
04Provides task-specific reference files

Use cases

01Editing generated Go code or templates
02Debugging unexpected generated output
03Changing SDK interfaces or client generation

Install

Copy the command and run it in a terminal.

Dagger Codegen

When to Load This Skill

Editing dagger.gen.go or internal/dagger/dagger.gen.go output
Modifying Go templates in cmd/codegen/generator/go/templates/
Changing SDK interfaces in core/sdk.go
Working on dagger develop, dagger call, or dagger client install
Debugging why generated code looks wrong

Critical Concepts

"Codegen" means 4 different things in Dagger:

#	Name	Trigger	Key Files
1	In-Module Bindings	`dagger develop`	`cmd/codegen/generator/go/templates/`
2	Runtime Dispatch	Module startup	`cmd/codegen/generator/go/templates/modules.go:140`
3	SDK Libraries	`go generate`	`sdk/go/generate.go`
4	Generated Clients	`dagger client install`	`_dagger.gen.go/client.go.tmpl`

Know which one you're dealing with before editing.

Key Entry Points

To change...	Edit
Generated method signatures	`cmd/codegen/generator/go/templates/src/_types/object.go.tmpl`
Generated type definitions	`cmd/codegen/generator/go/templates/src/_types/*.go.tmpl`
Module `invoke()` dispatch	`cmd/codegen/generator/go/templates/modules.go:140`
Standalone client `Connect()`	`cmd/codegen/generator/go/templates/src/_dagger.gen.go/client.go.tmpl`
Template functions	`cmd/codegen/generator/go/templates/functions.go:54`
SDK interfaces	`core/sdk.go:20` (ClientGenerator), `:93` (CodeGenerator)
Built-in SDK list	`core/sdk/consts.go`
Python output	`sdk/python/codegen/src/codegen/generator.py`
