The SKILL.md contract says every stdout line is one JSON event, but
createProject wrote the Created/Next-steps templates to stdout and the
default install/build path inherited the launcher's stdio, so package-
manager child output interleaved with the event stream. Under --json,
route human progress to stderr and run install/build through a
NodeCommandRunner that redirects child stdout+stderr to stderr.
dsh-sdk's usage template predates the create command and create-sdk's
predates --config/--config-json/--json, so --help hid both surfaces the
README already documents. Pin each with a help-output assertion.
Regenerate docs/config-catalog.md for the telemetry package, unwrap the
design doc's multi-line blockquote paragraphs, and stop exporting the
create-sdk headless spec internals that have no external consumer.
Add a headless create path: --config <file> / --config-json <json> supply a
structured project spec (answers + feature plan) that drives CreateWizard through
a HeadlessPromptPort, bypassing the TTY. --json emits NDJSON lifecycle events
(done / action-required / error) so an agent can fill a missing input and re-run.
Ship a thin SKILL.md playbook for agent-driven creation. Per-file 100% coverage.
Add HeadlessPromptPort (fail-loud non-interactive PromptPort), thread
prefilled feature values through FeatureConfigurator, and let CreateWizard
and ConfigWorkflow accept a headless feature plan that skips the interactive
tree/suggests prompts. Per-file 100% coverage on all changed files.
