# Promptkit v0.20.0

This minor release adds generically renderable resource inspection and typed
prompt source construction. The Go consumer minimum remains 1.27.0 and
ConfigKit remains at v1.1.0.

## Compatibility And Migration

`InspectProfile` now returns the resolved profile resource instead of the
backend-completed `EffectiveModelParams`. Replace accesses to that field with
the optional profile fields; use `Prepare` or `PreparedExecution.Details` for
completed request settings. `InspectPrompt` now includes captured messages and
uses optional pointers for presence-sensitive fields, including default profile,
inputs, input metadata, and output settings. Check pointers before dereferencing.
All three resource reports support ordinary JSON and YAML rendering without
per-field adapters. See the [consumer guidance](../consumers/pkg-promptkit.md#inspect-a-profile-before-prompt-work).

After configuration composition and inheritance, profile null endpoint,
API-key source, and whole provider map now permit backend defaults during
execution as well as appearing absent in resource inspection. Use explicit
empty strings to clear endpoint or API-key source. There is no replacement for
profile-level suppression of an entire backend provider map; edit backend
defaults through composition instead. The required-key rule still applies.
See [defaults and overrides](../formats.md#defaults-and-overrides) for the
migration example and retained ConfigKit null provenance.

## Resource Inspection And Sources

`InspectBackend` reports the resolved backend and configured diagnostics without
contacting a provider or deriving diagnostic destinations. Prompt and profile
inspection likewise report selected resources independently of request readiness;
configuration provenance, requirement analysis, and preparation remain separate.
`PromptSource` adds typed programmatic prompt definitions, and `BackendConfig`
supports sibling inheritance. ConfigKit continues to own source composition,
snapshotting, and relative message-file contexts.
