# Composed consumer

This example is part of the ckprompt module and uses core v0.4.0, ckconfig
v0.3.0, ConfigKit v1.1.0, and PromptKit v0.20.0. It requires Go 1.27.0.
The current work uses the aligned local workspace until the required ckconfig
release is published.

This example composes application configuration, PromptKit configuration,
PromptKit comparison and catalogs, definition and requirements inspection, and
one application-owned command:

```sh
go run . config scopes
go run . config validate --scope all --campaign spring --limit=0
go run . config diff --scope app --config fixtures/before.yml --against-config fixtures/after.yml
go run . config diff --scope app --config fixtures/before.yml --against-config fixtures/after.yml --campaign spring --limit=0
go run . config diff --scope app --campaign spring --limit=0 --against-campaign autumn --against-limit=0 --set '/campaigns/spring/model="left"' --against-set '/campaigns/spring/model="right"' --details
go run . config diff --scope promptkit --config fixtures/before.yml --against-config fixtures/after.yml --campaign spring --against-campaign spring
go run . promptkit list prompts --config fixtures/before.yml --campaign spring
go run . promptkit list profiles --config fixtures/after.yml --campaign autumn --format yaml
go run . promptkit list backends --campaign spring
go run . promptkit list namespaces --campaign spring
go run . promptkit list collections --campaign spring
go run . list collections --campaign spring
go run . pk list bundles --campaign spring
go run . promptkit list prompts --namespace field-notes --campaign spring
go run . promptkit show prompt briefing --campaign spring --format yaml
go run . promptkit show prompt briefing --campaign spring --prompt-namespace field-notes
go run . promptkit show prepared briefing --campaign spring --input topic=sprint --profile spring --extra-params '{"campaign":"preview"}'
go run . pk show prompt briefing --campaign spring --fmt yaml
go run . promptkit show profile spring --campaign spring
go run . promptkit requirements show briefing --campaign spring
go run . promptkit requirements show briefing --campaign spring --var mode=full --format yaml
go run . promptkit requirements validate briefing --campaign spring --llm-input-file topic=fixtures/topic.txt
go run . promptkit requirements validate briefing --campaign spring --llm-input-file topic=fixtures/topic.txt --llm-var mode=full --llm-input-file notes=fixtures/notes.txt --format yaml

```

`newApp` installs application-owned command and flag aliases alongside the
complete `ckconfig` and `ckprompt` declarations. `list collections` and
`promptkit list bundles` both reach the canonical collection command; `pk`
shortens the PromptKit group. `--fmt` is scoped to named prompt inspection and
`--hlep` is available globally. The `smoke` shortcut retains the canonical
`promptkit test KIND` operand, including the special `all` aggregate.

The example installs `Completion("composed-example")`. Build it as
`go build -o composed-example .`. Initialize `bash-completion` first if using
Bash, then load a shell script as described in the
[CLI reference](../../../../docs/cli.md#shell-completion). Try completion after
`composed-example pk show prompt briefing --fmt=` or after the filename prefix
in `composed-example config show --config=fixtures/`. The already-entered `pk`
alias selects the PromptKit command context without loading an engine.

The composition installs `ckconfig.Command(suite)` and the complete
`ckprompt.Declarations(definitions)` in a `[]commandkit.Declaration` with
root-installed routing rules. The PromptKit declarations include scoped aliases;
the application-owned `request inspect` command reuses the flag collections
with their canonical names and does not install those aliases.
Group children remain canonical `Command` values. For command-only slices,
convert each `Command` to `Declaration` before appending aliases. The
[consumer guide](../../../../docs/consumers/guide.md#application-owned-aliases)
includes minimal direct-call and slice-conversion examples; this README documents
the maintained complete consumer.

The sources and session store are small in-memory fixtures. `--campaign` is a
typed selector shared by the app and PromptKit configuration scopes. Their
`ckconfig.Suite[*inspectionInput, *runCache]` uses `NewInput` to initialize each
selected scope's input separately and `NewState` to create one cache shared by
that invocation's acquisitions. Prompt/profile inspection prepares its input and
cache independently for its invocation, using the same application and engine
loader functions. See the
[consumer guide](https://gitea.maximumdirect.net/eric/CommandKit/src/branch/main/docs/consumers/guide.md)
and the suites' GoDoc for initialization timing and ownership.

The application-scope comparison reports the changed default campaign and the
updated `campaigns.spring.model`. The PromptKit-scope comparison selects spring
on both sides and reports the native engine change in the atomic profiles list.
The application input check requires `--limit=0` when `--campaign` is supplied.
Catalogs use the same selection-aware loader: the prompt catalog includes
`briefing`, and the profile catalog includes the selected `autumn` profile.
Prompt inspection uses an ID only. The default PromptKit bundle also contributes
profiles and a backend to the engine inventory and source reports. The synthetic `field-notes` collection
provides one backend, profile, and prompt for collection discovery and native
namespace filtering. The example's shared run cache keys successful results by
the complete supplied configuration/overlay selection, CLI overrides, and the
supplied campaign, including presence. The campaign override and application
scope's `--set` records are applied through ConfigKit before loading. The
PromptKit configuration scope does not enable `--set` because its released
configuration loader has no override handoff. An aggregate operation therefore
rejects overrides when that scope is selected. These are choices for this
example's loaders and do not define a CommandKit cache policy.

Smoke testing is explicitly wired with `ckprompt.WithSmokeTesting` and its
optional request builder is nil, so CommandKit forwards the selected native
request. Applications that need to adjust the request can provide a typed
builder that starts with the seed and returns the chosen native request:

```go
definitions = ckprompt.WithSmokeTesting(definitions, loadEngine,
	func(ctx context.Context, seed ckprompt.SmokeRequest, input *inspectionInput, state *runCache) (promptkit.SmokeTestRequest, error) {
		request := seed.Request
		request.ProfileID = "spring"
		return request, nil
	})
```

The example injects a small in-memory `promptkit.LLMClient` through its shared
run state. Catalog, inspection, and requirements commands do not call it;
inference smoke commands do. No model service or credentials are required.
Native HTTP checks may retain unsupported or not-applicable observations because
the selected local backend does not configure a network probe. An aggregate smoke command can
return an operational outcome for a native diagnostic while still delivering
the complete aggregate report.

The first requirements command reports incomplete discovery: PromptKit records
the conditional `notes` input and a missing `mode` issue. Supplying `mode=full`
selects that branch, classifies the undeclared `notes` input as required, and
completes discovery. Both commands return successful reports; the result does
not execute the prompt or establish input, credential, or execution readiness.
See the [CLI reference](../../../../docs/cli.md#promptkit-requirements) for the
command and report contract.

The validation and preview commands exercise concrete PromptKit request preparation.
The first uses the builder's campaign-specific default topic variable and the
operator's topic file. The second also selects the notes branch and supplies its
file. Validation reports only `prompt_id` and `valid: true`; preview returns the
prepared request, including rendered messages and effective provider settings.
Neither executes the prompt. The validation command without inputs intentionally
fails because the prompt's
required `topic` artifact is not supplied. The builder defaults variables from
the selected campaign but leaves artifact bindings to the operator. The
`requirements show` commands remain discovery reports: partial discovery can
succeed even when a concrete request would fail validation.

Use the aligned local workspace to test the three current sources, as described in
the [developer guide](../../../../docs/development.md#documentation-validation).
Once released dependency requirements are aligned, `GOWORK=off go test ./...`
from this example directory checks it against its declared dependencies.
