# Promptkit v0.7.0
This supplemental changelog and migration guide summarizes the consumer-facing
changes from `v0.6.0` to `v0.7.0`. The annotated `v0.7.0` tag is the
authoritative release record. Exact current contracts belong to the linked
GoDoc and durable documentation.
## Summary
`v0.7.0` expands provider integration and profile composition while making
credential and generation-failure handling more flexible:
- Promptkit now includes the `rakestrawhome` backend and its Gemma profile;
- built-in generation failures expose bounded structured provider details;
- an unavailable optional API-key environment source no longer prevents a
request from reaching an upstream that permits unauthenticated access; and
- profiles can inherit from and selectively refine another profile.
## Compatibility
This release adds public declarations and fields but removes none. Existing
keyed configuration literals and ordinary `errors.Is` handling continue to
work.
Adding `BaseProfileID` to `Profile` and `OpenAICompatibleProfileConfig` changes
their struct shape. Consumers using positional composite literals for either
type must convert them to keyed literals. Existing keyed literals require no
change.
The `rakestrawhome` backend ID is now built in and reserved. A consumer that
previously registered that exact ID with `WithBackend` must remove its manual
registration before upgrading. Other custom backend registrations are
unchanged.
When an optional backend, profile, or request `APIKeyEnv` is unset, empty, or
whitespace-only, the built-in client now omits `Authorization` and sends the
request. Previously this condition could fail before transport. Set
`Profile.APIKeyRequired` when missing credentials must remain a local
preflight error.
Provider non-success responses continue to match `ErrLLMGenerate`. Their
rendered wording is not a compatibility contract; consumers can now use
`errors.As` with `*GenerationError` when structured status information is
needed.
## Upgrade
Update the module dependency with:
```sh
go get gitea.maximumdirect.net/eric/promptkit@v0.7.0
go mod tidy
```
Remove any manual `rakestrawhome` backend registration, convert positional
profile literals to keyed literals, and run the consuming project's ordinary
and race-enabled tests.
## Rakestrawhome Built-In Backend And Profile
Every engine now includes the reserved `rakestrawhome` backend, identified by
`BackendRakestrawHome`. The built-in `rakestrawhome-gemma-4-31b` profile
selects that backend. Consumers can use the maintained endpoint, credential,
capacity, and model defaults without registering either definition themselves.
See the [built-in backend and profile catalogs](../formats.md#built-in-backends)
and the [consumer adoption example](../consumers/pkg-promptkit.md#use-the-rakestrawhome-built-in-profile)
for the current contracts.
## Structured Generation Errors
Non-2xx responses from the built-in OpenAI-compatible client now return an
immutable `*GenerationError`. Consumers can inspect the HTTP status and any
safely extracted provider code, type, or message while retaining the ordinary
generation-error category:
```go
var generationErr *promptkit.GenerationError
if errors.As(err, &generationErr) {
status := generationErr.StatusCode()
_ = status
}
```
Provider fields are bounded and normalized but remain untrusted and may
contain sensitive request or schema details. Default and Go-syntax formatting
omit those fields. Applications must apply their own disclosure policy before
logging or presenting accessor values.
See the [`GenerationError` GoDoc](../../generation_error.go), the
[consumer error-handling guide](../consumers/pkg-promptkit.md#handle-errors),
and the [OpenAI-compatible response contract](../integrations/openai-compatible-chat.md#response-handling).
## Optional Credential Sources
`APIKeyEnv` names an optional environment lookup source unless the selected
profile explicitly sets `APIKeyRequired`. When neither a direct request key nor
a usable environment value exists, the built-in client omits the bearer header
and handles the upstream response normally. This supports local and other
OpenAI-compatible providers that permit unauthenticated requests without
hiding an authentication error returned by a provider that requires one.
The [credential format reference](../formats.md#credentials), the
[`Backend` GoDoc](../../backends.go), the
[`ExecutionTargetOverride` GoDoc](../../types.go), and the
[authentication integration contract](../integrations/openai-compatible-chat.md#authentication)
define the current precedence and availability rules.
## Profile Inheritance
YAML profiles can name one parent with `base_profile`; in-memory profiles use
`Profile.BaseProfileID`, and `OpenAICompatibleProfileConfig` forwards the same
field. A profile can act as an application-owned alias of a built-in or refine
selected inherited settings:
```go
promptkit.WithProfiles(promptkit.Profile{
ID: "weather-light",
BaseProfileID: "deepseek-4-flash",
ReasoningEffort: "high",
})
```
Base lookup observes the existing source precedence. Chains are linear,
cycle-safe, and resolved afresh for ordinary operations. Prepared execution
freezes the fully resolved target. The selected leaf ID remains public while
effective execution settings reflect the resolved chain.
See the [profile inheritance format reference](../formats.md#profile-inheritance),
the [consumer alias example](../consumers/pkg-promptkit.md#alias-a-built-in-profile),
and the [`Profile` GoDoc](../../types.go) for exact merge and validation
behavior.
## Public API Changes
The release adds:
- `BackendRakestrawHome`;
- `GenerationError`, including `StatusCode`, `ProviderCode`, `ProviderType`,
`ProviderMessage`, `Error`, `GoString`, and `Unwrap`;
- `Profile.BaseProfileID`; and
- `OpenAICompatibleProfileConfig.BaseProfileID`.
No public declaration was removed.
## Consumer Action
- Remove a manual backend registration whose ID is exactly `rakestrawhome`.
- Convert positional `Profile` or `OpenAICompatibleProfileConfig` literals to
keyed literals.
- Set `Profile.APIKeyRequired` where a missing credential must fail locally
instead of reaching the provider unauthenticated.
- Treat `GenerationError` provider fields as untrusted and potentially
sensitive when adopting the new accessors.
- Run consumer ordinary and race-enabled tests after updating the module.
