Add create, update and delete scene commands - #131
Scenes could be listed and activated but not authored. This adds:
openhue create scene <name> -r <room>: saves the current look, or defines each light with --light "<light>:<settings>" (on/off, brightness, color, temperature, transition, effect, gradient), defaults flags, dynamic settings (--speed, --auto-dynamic, --palette-*), --only-listed, --dry-run, --json.
openhue update scene <scene>: edits a stored scene (lights, defaults, --name, --remove-light, --clear-palette). Lights not mentioned keep their stored values, effects and gradients included.
openhue delete scene <scene>.
--from-file <path|-> (YAML) on create/update, and openhue get scene <scene> --yaml to export. Export then re-apply is a no-op; export then create gives an equivalent scene. See docs/examples/scene.yaml.
Real lights are never changed. Design and specs are in openspec/changes/add-create-scene-command.
Reviewer notes
Verified against a real bridge (Studio room): create, update, export/re-apply, clone, delete.
The bridge requires every light of the room in a scene, so --only-listed and --remove-light turn the other lights off instead of leaving them out.
Other bridge rules handled: an effect cannot be combined with color/temperature/gradient; palette entries need a brightness; lights without dimming skip a default brightness (warning).
The bridge answers 201 Created to a creation and openhue-go v1.0.0 treats it as an error. The CLI works around it by looking the scene up by name; the proper fix belongs in openhue-go.
Builds on the openhue-go v1.0.0 migration (go.mod, home_*, cmd/get/*), included in this branch. gopkg.in/yaml.v3 becomes a direct dependency.
Gradient lights could not be tried on the bridge (none in that room); covered by unit tests only.
Create, update, delete, and export Hue scenes from the command line, selecting scenes by name or ID.
Define scenes in YAML files or through standard input, with support for room-wide defaults, per-light settings, dynamic palettes, and partial updates that preserve unmentioned settings.
Preview proposed changes with --dry-run and use JSON output where available. Scene export includes room and light settings.
Documentation
Added scene command guidance and a sample YAML definition.
The CLI adds scene creation, updates, deletion, and YAML export. Shared scene definitions support validation, YAML files or stdin, and flag overrides. Scene builders construct create and update requests, while scene services handle lookups and bridge operations.
Changes: Scene management
Layer / File(s)
Summary
Client model adaptation go.mod, openhue/home_context.go, openhue/home_model.go, openhue/home_service.go, cmd/get/*, cmd/mcp/tools.go
Bridge calls and resource handling use the updated client’s context arguments and value-based generated fields.
Scene definitions and YAML openhue/scene_definition.go, openhue/scene_yaml.go, openhue/scene_definition_test.go, docs/examples/scene.yaml, openspec/changes/add-create-scene-command/specs/scene-definition-file/spec.md
Adds scene-definition types, validation, light-setting parsing, definition merging, and YAML loading and marshaling. The example contains scene settings and a commented update removal.
Scene request construction openhue/scene_builder.go, openhue/scene_builder_test.go, openhue/fake/fixtures.go
Builders create scene actions from room-light state and settings. Update requests merge changes with stored actions and palettes. Tests cover capabilities, defaults, removals, and preservation of existing actions.
Scene commands and bridge operations cmd/scenecmd/flags.go, cmd/create/*, cmd/update/*, cmd/delete/*, openhue/scene_service.go, cmd/root.go, openspec/changes/add-create-scene-command/*
Registers create, update, and delete commands. Shared flags resolve and validate inputs; scene services look up scenes and send create, update, and delete requests.
openhue/openhue-cli#80: Both changes touch GroupedLight.IsOn behavior and room-state handling.
openhue/openhue-cli#91: Both changes address grouped-light brightness handling in room output.
Merge Risk: Low · up to 484ca
Exporting a scene and cloning it silently drops per-light transition times. Entering NaN for brightness, color or speed yields a confusing JSON error instead of a validation message. Both are narrow edge cases with simple fixes, so the PR is mergeable once the owner knows about them.

## What
- Move the AI assistant guidance from `CLAUDE.md` to a new `AGENTS.md`,
so it is usable by any coding assistant. `CLAUDE.md` now only imports it
(`@AGENTS.md`).
- Add the OpenSpec slash commands (`/opsx:*`) and skills under
`.claude/` used to propose, apply and archive changes.
## Reviewer notes
- Docs/tooling only, no code change.
- Separate from #131 (scene commands), which uses the OpenSpec workflow;
meant to be merged first.
🤖 Generated with [Claude Code](https://claude.com/claude-code)
Scenes could be listed and activated but not authored. Add:
- `create scene`: from the current state of a room, per-light settings
(--light, transitions, effects, gradients), defaults, dynamic palette,
--only-listed, --dry-run, --json
- `update scene`: edit a stored scene (lights, defaults, rename, palette,
--remove-light), unmentioned lights keep their stored values
- `delete scene`
- `--from-file` (YAML, `-` for stdin) on create and update, and
`get scene --yaml` to export a scene in the same format
The bridge requires every room light in a scene, so --only-listed and
--remove-light turn the other lights off instead of leaving them out. It
also answers 201 to a creation, which openhue-go reports as an error: the
scene is looked up by name in that case.
Builds on the openhue-go v1.0.0 migration. Includes the OpenSpec change.
openhue-go v1.0.0 treats a non-200 scene creation response as ApiError. For a 201 response, Room.CreateScene lists scenes and matches the room ID and scene name. Add two cases: one that returns the matching scene ID, and one that returns scene created but not found afterwards.
Mock GetScenesWithResponse with HTTP 200 and JSON200.Data containing the matching SceneGet.

Reject NaN in float validation.
strconv.ParseFloat accepts "NaN". These inputs therefore produce NaN values:
--light "Desk:brightness=NaN"
x=NaN
--speed NaN (pflag uses ParseFloat)
xy@NaN/0.5
YAML .nan
Every comparison with NaN is false. As a result, these guards pass NaN:
the range checks at Line 149 and Line 158
the speed check at Line 85
the palette brightness check at Line 132
the ParseColor check at Line 253
The builder then puts NaN into the request. encoding/json cannot encode NaN, so --dry-run and the bridge call fail with json: unsupported value: NaN. The definition passed validation, so the user does not get an error that names the bad setting.
Add math.IsNaN and math.IsInf checks next to each range check. A small helper such as outOfRange(v, lo, hi float64) bool keeps the change local.
Based on learnings: "Reviewers should require explicit math.IsNaN and math.IsInf checks alongside range checks whenever validating float64 values parsed from external input."
🛡️ Proposed fix
- if s.Brightness != nil && (*s.Brightness < 0 || *s.Brightness > 100) {+ if s.Brightness != nil && outOfRange(float64(*s.Brightness), 0, 100) {
return fmt.Errorf("brightness must be between 0 and 100, current value is %.2f", *s.Brightness)
}
@@
- if s.X != nil && (*s.X < 0 || *s.X > 1 || *s.Y < 0 || *s.Y > 1) {+ if s.X != nil && (outOfRange(float64(*s.X), 0, 1) || outOfRange(float64(*s.Y), 0, 1)) {
return fmt.Errorf("x and y must be between 0 and 1")
}
Apply the same helper to Speed (Line 85), palette brightness (Line 132) and ParseColor (Line 253).

Export the per-light transition (Dynamics.Duration).
actionToSettings never maps act.Dynamics.Duration to LightSettings.Transition. transition is a documented definition key (docs/examples/scene.yaml Line 21, and the spec of the definition file). The export spec also requires that a clone "has the same per-light settings".
If a stored scene has per-light transitions, create scene Copy --from-file <export> produces a scene without these transitions. TestExportCloneIsEquivalent does not detect this because the richScene fixture has no Dynamics.
Re-apply stays a no-op after the fix. applySettings writes the same Duration back from the exported value.
