Presets

Presets determine what dev environment, plugins, and secrets are configured when Bucky runs in a repository — both for code review workflows and EKS session pods.

Available presets

`web`

For Node.js/TypeScript projects. Detected by the presence of package.json.

Setup: Node.js with auto-detected package manager (pnpm or npm)
Plugins: common, web, typescript-lsp, frontend-design
Extra secrets: None
Marker file: package.json

Web preset setup detects .node-version or .nvmrc for version management, installs dependencies via pnpm install --frozen-lockfile or npm ci, and sets up Playwright for browser automation.

`golang`

For Go projects. Detected by the presence of go.mod.

Setup: Go via mise, with Artifactory Go proxy
Plugins: common, golang, gopls-lsp
Extra secrets: None
Marker file: go.mod

Go preset setup configures GOPROXY, uses mise for version management, and runs go mod download.

`none`

Fallback for projects that don’t match web or golang markers.

Setup: No dev environment setup
Plugins: common
Extra secrets: None
Marker file: Fallback

How presets are resolved

For code review workflows, preset resolution happens at runtime in the workflow. For EKS session pods, the agent resolves the preset when dispatching the pod.

Preset configuration lives in presets.json at the buck-bronson repo root:

{
  "web": {
    "setup_action": "setup-web",
    "plugins": [
      "common@buck-bronson",
      "web@buck-bronson",
      "typescript-lsp@claude-plugins-official",
      "frontend-design@claude-plugins-official"
    ],
    "secrets": {
      "sourcegraph-token": "SOURCEGRAPH_TOKEN"
    }
  },
  "golang": {
    "setup_action": "setup-golang",
    "plugins": [
      "common@buck-bronson",
      "golang@buck-bronson",
      "gopls-lsp@claude-plugins-official"
    ],
    "secrets": {
      "sourcegraph-token": "SOURCEGRAPH_TOKEN"
    }
  },
  "none": {
    "setup_action": null,
    "plugins": ["common@buck-bronson"],
    "secrets": {
      "sourcegraph-token": "SOURCEGRAPH_TOKEN"
    }
  }
}

At runtime, the workflow reads this file (from the v1 tag) and outputs:

plugins — multiline list of plugins to register
setup-action — which setup action to run (setup-web, setup-golang, or empty)
has-posthog-token — whether to inject the PostHog token

Plugin marketplaces

Two plugin marketplaces are registered in all sessions and workflows:

buck-bronson (./.buck-bronson) — common, web, golang plugins
claude-plugins-official (https://github.com/anthropics/claude-plugins-official.git) — typescript-lsp, gopls-lsp, frontend-design

Plugins from @buck-bronson are fetched from this repo. Plugins from @claude-plugins-official are fetched from the official Anthropic plugins repo.
