# PromptKit Adoption Outline

**Updated:** 2026-11-07

**Status:** Initial outline. Follow the [master roadmap](library-adoption.md)
for shared adoption principles, dependency identities, and sequencing.

## Baseline and Target

Audita currently uses PromptKit v0.14.0. Its
[LLM runtime](../internal/llm-runtime.md) uses a shared engine, application-owned
backend overrides, curated profile inspection, and prepared execution.

Adopt PromptKit v0.20.0 through its native configuration and execution APIs.
Retain the built-in OpenRouter backend and bundled profiles. They must be usable
through the normal selection and credential mechanisms, not merely visible in
an inventory while Audita rejects them for lacking a duplicate registration.
Expose native resource and configuration inspection through the full standard
ckprompt surface described in the [CommandKit outline](commandkit.md).

PromptKit owns resources, composition, provider settings and credentials,
preparation, transport, structural repair, and backend admission. Audita owns
proposal/validation role selection, transcript processing, domain decisions,
response contracts, and truthful partial-success reporting. Remove the existing
application-only endpoint and credential restrictions as described below.

Use the pinned [migration guide](https://forge.maximumdirect.net/base-layer/promptkit/src/commit/8ff9aa3efdc9f16b9d2729e0a29ea083eb3c3eaf/docs/consumers/configuration-migration.md),
[format reference](https://forge.maximumdirect.net/base-layer/promptkit/src/commit/8ff9aa3efdc9f16b9d2729e0a29ea083eb3c3eaf/docs/formats.md),
and [v0.20 release notes](https://forge.maximumdirect.net/base-layer/promptkit/src/commit/8ff9aa3efdc9f16b9d2729e0a29ea083eb3c3eaf/docs/releases/v0.20.0.md).
The bundle is default-on; older migration prose about catalog removal does not
mean the current release has no bundled resources. It does not select an implicit
execution profile or make provider calls during construction.

## Agreed Direction and Migration Work

### Backend Concurrency Ownership — Resolved

Adopt PromptKit's native per-backend concurrency behavior, including backend
defaults and supported configuration and CLI overrides. The purpose is to keep
requests within the concurrency a backend can accommodate; no separate Audita
domain requirement has been identified for an additional limit.

Remove Audita-owned concurrency settings, default injection, validation, and
enforcement wherever they duplicate or override that native behavior. Do not
retain a second limiter or impose an Audita-specific finite-cap requirement on
otherwise valid PromptKit configuration. Use the shared PromptKit engine so
proposal and validation work for the same backend share its admission control.
Audita still owns cancellation and deterministic processing around model calls.

Verify the exact upstream override APIs while wiring the adopted configuration
and CLI integrations. Update the architecture policy's finite-admission wording,
runtime documentation, examples, and tests with implementation. Remove superseded
behavior directly in the major release, with hard-cutover guidance.

### Backend and Credential Ownership — Resolved

Native PromptKit backend/profile resources are authoritative for endpoints,
provider settings, and credential selection. No domain-specific requirement has
been identified for a separate Audita ownership policy.

- Remove Audita's separate `backends` mapping and generated backend override
  layer. Remove duplicate registration requirements and checks that force profile
  endpoints to match an Audita-owned backend endpoint. Native selection and
  validation govern bundled and operator-defined resources.
- Use PromptKit's native credential sources and precedence. Remove Audita's
  LLM-specific credential references, automatic direct-key injection, and
  rejection of profile-level environment lookups. Backend/profile documents
  contain environment-variable names, not credential values; operators may use
  the bundled OpenRouter lookup or configure their own names.
- Follow native credential availability timing. Loading and resource inspection
  must not require credentials for every configured backend. Preparation and
  execution enforce the selected request's native required/optional semantics:
  missing optional credentials permit unauthenticated requests. Do not add an
  eager all-backend credential check or silently strengthen those semantics.

Audita retains role/profile selection, operation budgets, domain request
construction, response contracts, and safe handling of its reports and debug artifacts. Native
configuration redaction does not replace redaction at Audita's artifact boundary.
Keep preparing and executing the same captured request while retiring target
checks whose purpose was enforcing the removed application backend registry.

Remove superseded fields, code, and tests in the major-release cutover and update
the affected policies and current contracts with implementation. The ConfigKit
outline owns file discovery and import policy; those choices govern how native
resources are supplied, not who owns their semantics.

### Bundled Prompts and Operator Replacements — Resolved

Ship Audita's production default prompt definitions in `embed.FS`, exposed as
`io/fs.FS`. Load them through PromptKit's filesystem inputs into a ConfigKit
underlay, with operator sources at higher priority. Using the shipped prompts
must not require a separate external prompt installation.

Place all Audita-owned default prompts in the native `audita` collection
namespace. Keep local IDs such as `modules.glossary.proposal`; callers use the
qualified runtime ID `audita/modules.glossary.proposal`. Update registry entries,
call sites, references, examples, and diagnostics accordingly. Mounting a source
does not rewrite references, so qualified references must be explicit.

Operators may replace individual prompts or supply a complete replacement set
by defining the same collection and local IDs in higher-priority sources.
Unreplaced prompts continue to come from the underlay. Follow native whole-record
replacement semantics for matching IDs and document the required complete prompt
definitions. The namespace identifies Audita's prompts without making them
immutable or requiring a separate development mode.

The development workflow is edit external definitions and rerun Audita using the
same binary. A newly constructed runtime captures the changed definitions and
message files; live reload within an active run is not required. The same
mechanism supports production customization. Standard inspection, provenance,
and request preview must make effective prompts and their origins understandable.
Audita's response schemas and domain validation continue to apply.

External source selection follows the [ConfigKit discovery/import plan](configkit.md).
This workflow is required PromptKit adoption scope and should use
native composition rather than a separate prompt loader or override system.

### Profile Inspection and Summary — Resolved

Retire `config print-effective --view profiles` and its Audita-owned summary
code. Use application configuration inspection to show proposal/validation
profile selections, standard PromptKit resource inspection for profile/backend/
prompt definitions, and request preview for resolved execution settings and
rendered messages. These views have distinct meanings and must be presented as
such.

Do not add a replacement custom role summary at this stage. Native interfaces
cover the selected needs and reduce maintenance without a parallel target
resolver. Include the retired view and its standard replacements in the
hard-cutover guidance. The [CommandKit outline](commandkit.md) owns the operator
surface and request-preview integration work.

### Migration Work

1. Move to `go.maximumdirect.net/promptkit` together with ConfigKit's new types.
   Remove the old external catalog dependencies when no longer incorporated;
   retain PromptKit's built-in catalog rather than disabling it.
2. Convert root and collection backends, profiles, and prompts to identified lists
   with explicit `id` fields. Use sibling `extends: {id: parent}` and complete
   same-ID replacement records. Typed source builders use ordered slices.
   Preserve provider settings deliberately: partial same-ID replacements no
   longer merge fields. Use exact native collection references where collections
   are selected; mounting does not rewrite stored references.
3. Convert the seven embedded prompts into the `audita` collection and update
   maintained operator examples/fixtures for the resolved replacement workflow.
   Remove prompt version selectors and descriptive `PromptVersion` metadata from
   requests, registries, inspection, and diagnostics. Response-schema versions
   are separate and need not change. Keep domain instructions and per-call schemas;
   this adoption is not a prompt-quality rewrite. Shared instruction variables
   remain available to templates, while native operator overrides control their
   inclusion. Domain validation remains enforced after model responses.
4. Adapt resource inspection to optional profile fields and separate backend
   inspection. These describe resources, not completed requests. Use real
   `PrepareExecution` details and `RunPrepared` for execution of the same captured
   request. Remove the curated profile view and its supporting projection code;
   do not duplicate PromptKit's full resolver or construct synthetic requests
   merely to reproduce that summary. Inspect bundled and unselected partial
   resources without requiring them to be runnable.
5. Implement the resolved backend and credential ownership decision above.
   Replace application backend/credential configuration with native resources
   and document the hard cutover. Preserve secret-safe diagnostics using the
   library's public boundaries and Audita's domain artifact redaction; evaluate
   actual gaps with synthetic keys.
6. Review presence semantics field by field. Null endpoint, credential-source,
   and whole provider map now allow backend defaults; explicit empty strings
   clear endpoint/credential sources. Null does not suppress the entire backend
   provider map. Sampling fields have distinct semantics. Avoid blanket null or
   zero conversion and document intentional request changes.
7. Update captured-source accounting for list indexes and collection prefixes,
   including inherited/moved content-file origins. Preserve output-collision
   protection for consumed host documents and effective message files. Array
   positions are addresses, not durable resource identities.
8. Keep self-contained embedded response schemas. The new schema rule does not
   require a bundler for Audita's current schemas. Check custom artifact-reader
   ownership only where such a reader is actually used. Preserve native retries,
   structural repair, cancellation, deadlines, and shared engine admission while
   retaining Audita's domain reconciliation and partial-success outcomes.

Update [configuration](../config.md), [LLM integration](../integrations/openai-compatible-llm.md),
[runtime internals](../internal/llm-runtime.md), [prompt guidance](../internal/prompts.md),
operator examples, diagnostics metadata documentation, and attribution with the
implementation. Standard inspection replaces curated-only disclosure; prompts
and provider settings may appear where the library's normal inspection exposes
them, with native redaction. Do not accidentally promise old prompt hashes.

## Acceptance and Upstream Requests

Verify native bundle inventory and selection, configuration/resource/prepared
view distinctions, inheritance and replacement, credential precedence, optional
fields, source-relative messages and collisions, and captured configuration.
Use controlled providers to verify actual targets, domain schemas, shared
admission, retry/repair budgets, cancellation, and partial success. Standard
inspection must work without model calls; library presence alone does not prove
successful Audita integration.

Verify backend defaults and explicit concurrency overrides through the assembled
application, including shared admission across proposal and validation roles.
Check that Audita no longer injects an additional limit or rejects native settings
under its former finite-cap policy. Keep integration coverage for Audita's wiring;
remove tests that only preserve retired local concurrency behavior.

Verify native bundled and custom backend selection without duplicate Audita
registration, supported profile endpoint and credential overrides, and inspection
without credential availability. Use controlled requests to cover required-key
failures and optional unauthenticated execution under native semantics. Check
that no application override layer or direct-key injection defeats native
precedence, and that synthetic keys stay out of Audita diagnostics and artifacts.

Verify the embedded `audita` prompts work without external prompt definitions.
Exercise both individual-prompt and complete-set replacements using native
collection IDs, checking that unreplaced defaults remain available. Demonstrate
that editing external prompt/message files changes a newly constructed runtime's
prepared request without rebuilding the binary, while the existing runtime keeps
its captured inputs. Check qualified-ID selection, effective prompt inspection,
source provenance, and continued response-schema and domain validation with
controlled responses. Include a maintained edit-and-rerun example for developers.

Verify that role selections are visible in application configuration inspection,
resources through standard inspection, and completed request settings through
preview. Remove tests and examples that only preserve the retired curated view;
cover its replacement workflows through the assembled CLI.

No upstream request is yet selected. PromptKit is mature but pre-v1: significant
blockers or awkward public boundaries can justify focused requests. Submit the
minimal reproducer, desired outcome, and domain justification before building
substantial local machinery. A review probe demonstrated distinct base/derived
backend records preserving provider fields; that is an available native technique,
not a decision to retain Audita's old backend ownership model.
