feat(chat)!: generic requests replace the ask-user questions/answers API by rpvilo · Pull Request #75 · Intentface/intentface-chat

rpvilo · 2026-08-21T21:49:31Z

Closes CHAT-25.

Tool approvals ("Run delete_file? Allow once / Deny") needed the ask-user widget, but the API made them impossible without a third submit variant: questions were identified by display text, and answers came back as a four-variant union. This makes the mechanism generic instead — an approval is just a request, and the package never learns the word "approval".

The design

Three changes carry everything:

Consumer-minted ids. ComposerRequest requires an id the consumer supplies and gets back. Routing needs no help from the library — onSubmit closes over the state that produced the requests.
Option values. Options gain an optional value echoed back in entries (label fallback), so decision vocabularies ("once" / "deny") are the consumer's, not display strings.
One flat entry. The four-variant union becomes { id, selected: string[], text? } — text present only when typed, skipped entries have selected: []. One term throughout: requests in, resolved requests back.

Full rationale, rejected alternatives (tagged unions, meta passthrough, type parameters), and the scope boundary live in CHAT-25.

Migration

Before	After
prop `questions`	`requests` (entries require a consumer-minted `id`)
`AskUserQuestion` / `AskUserOption`	`ComposerRequest` (`question` → `label`) / `ComposerRequestOption` (+`value?`)
`ComposerAnswerEntry` (4-variant union)	`ComposerRequestEntry` — flat `{ id, selected, text? }`
`kind: "answers"`, `data.answers`	`kind: "requests"`, `data.requests`
slice `composer.askUser` (`questions`, `answers`)	`composer.requests` (`items`, `drafts`) — `items` avoids the `requests.requests` stutter, mirroring `attachments.items`
`setQuestions` / `activateAskUser` / `submitAnswersRef`	`setRequests` / `activateRequests` / `submitRequestsRef`
`interpretAskUserKey`, `hasActiveAskUser`, `"ask-user-arrow"`/`"ask-user-dismiss"`	`interpretRequestKey`, `hasActiveRequests`, `"request-arrow"`/`"request-dismiss"`
`@intentface/chat/ask-user`, `AskUser.*`, `useAskUserOption(s)`	`@intentface/chat/ask`, `Ask.*`, `useAskOption(s)`
`data-ask-user-*`	`data-ask-*`

The changeset (minor, pre-1.0) carries the same table.

Package

ask-user-machine.ts → request-machine.ts. compileRequests emits the flat entries and translates toggle keys to option values (value ?? label, tolerant of either wiring), so existing label-keyed widgets keep working while entries carry values. The machine still enforces option-XOR-text for single-select — the behavior stays; the payload type just no longer encodes it.
RequestDraft (the per-step { selected: Set, freeText } working state) is now exported — it previously leaked structurally through the slice with no public name.
src/ask-user/ → src/ask/; the old AskUserOption type-vs-component name collision disappears (ComposerRequestOption vs Ask.Option).
The store's event-scoping selector ([data-ask-options]) renamed in lockstep with the widget attributes.

App boundary (the design demonstrated)

The playground's tool vocabulary — the askUser tool, tool-askUser parts, getAskUserInfo — intentionally keeps its names: that vocabulary belongs to the consumer. Only the seam changes: chat.tsx mints positional ids (q-${index}) when mapping tool questions to requests, memoized over the merged demo+tool feed because setRequests resets the machine on array-identity change. The submit handler routes entries by id and rebuilds the tool's Record<question, answer> output byte-identically, including dismissed questions staying absent.

Dead AskUser.Summary styled wrapper deleted (zero consumers).

Docs

composer.mdx request-flow sections rewritten; the audited questions prop row renamed with the code.
ask-user-flow.tsx → ask-flow.tsx, now demonstrating option values.
New approval-flow.tsx demo — a pnpm test command approval rendered through the generic mechanism: tool call id as request id, numbered options, free text as "deny with a reason", no step-navigation parts. Styled as a sibling of the ask flow, done-state included.

Verification

All CI gates run locally in CI order: changeset status (staged check), biome, app tsc, package tests (197 pass, 5 new compileRequests behavior tests: value echo, label fallback, text omission, skip shape), package build + publint (11/11 dist entries load incl. ./ask), demos portability gate, docs audit, app build. Grep gates: zero data-ask-user/AskUser outside the app's own tool vocabulary.

Notes

Aria-labels "Previous question"/"Next question" stay: Navigation only mounts for multi-step flows, and the defaults are overridable.
The unmerged demo-deck branches (feature/demo-route/feature/demo-deck) reference data-ask-user-* and will need updating when rebased.
CHANGELOG.md history untouched.

📝 Walkthrough

Walkthrough

The Composer ask-user flow was replaced with a generic request flow. Public types, state, keyboard actions, package exports, components, integrations, documentation, demos, and tests now use request-oriented APIs.

Changes

Generic request flow

Layer / File(s)	Summary
Request contracts and Ask API `packages/chat/src/composer/types.ts`, `packages/chat/src/ask/*`, `packages/chat/package.json`	Added consumer-defined request contracts, request submission entries, the `@intentface/chat/ask` entry point, and renamed Ask primitives and data attributes.
Request state and submission flow `packages/chat/src/composer/request-machine.ts`, `packages/chat/src/composer/store.ts`, `packages/chat/src/composer/root.tsx`, `packages/chat/src/composer/keyboard.ts`	Renamed Composer state and actions, stored request drafts, resolved option values, and emitted `kind: "requests"` submissions.
Ask and Composer integration `components/ai/ask.tsx`, `components/ai/composer.tsx`, `components/chat.tsx`	Added the styled Ask compound component and wired Composer request rendering, selection, navigation, dismissal, continuation, and submission handling.
Documentation and demos `content/docs/primitives/composer/*`, `CHAT_ARCHITECTURE.md`, `COMPOSER.md`, `packages/chat/README.md`	Updated public API documentation and added ask-flow and tool-approval demos.
Validation and supporting updates `packages/chat/tests/*`, `packages/chat/src/types.ts`, `lib/ai/types.ts`	Migrated accessibility, keyboard, state-machine, and store tests to requests. Added message-part type guards and removed obsolete contract assertions.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to e6616

The generic request flow can currently return incorrect option values, respond to keyboard actions from unrelated controls, or open with no request content; these can cause incorrect consumer behavior and confusing interaction states. The PR needs targeted fixes before merge, with documentation and accessibility follow-up also required.

In `@CHAT_ARCHITECTURE.md`:
- Line 478: Update the documentation to consistently use the renamed request
panel-state shape: in CHAT_ARCHITECTURE.md lines 478-478, revise
ComposerPanelState; in CHAT_ARCHITECTURE.md lines 189-190, update the panel item
discriminator; and in COMPOSER.md lines 269-285, use the current request-state
discriminator for both panel values, removing the legacy "ask-user" and
questions terminology.

In `@components/ai/ask.tsx`:
- Around line 20-208: Add stable consumer-layer data-slot or data-role markers
to the rendered Ask wrappers, including AskRoot, AskHeader, AskOptions,
AskOption, and AskHints, and apply the same convention consistently to the other
exported Ask parts as appropriate. Keep these markers on the app-level wrappers
without modifying or copying package primitive attributes.

In `@components/ai/composer.tsx`:
- Line 619: Update the step label formatter using current and total so it
describes the count as “requests” rather than “questions,” preserving the
existing numbering and interpolation.
- Around line 631-636: Update the option identity in the display.options mapping
around Ask.Option to consistently use option.value ?? option.label for the React
key, value, selected lookup, and requests.toggleOption argument, so selections
emit the supplied value while preserving label fallback.

Apply the same fix in `@content/docs/primitives/composer/demos/approval-flow.tsx`
around lines 141 - 147: The ask demo has the same option identity mismatch.

In `@COMPOSER.md`:
- Line 70: Update the questions entry in the ComposerRequest documentation to
link to the existing “Add-on: questionnaire” heading using the generated
`#add-on-questionnaire` fragment, without renaming the heading.

In `@packages/chat/src/ask/ask.tsx`:
- Around line 85-95: Update the default aria-label values in AskPrevious and
AskNext to “Previous request” and “Next request” respectively, while preserving
their override behavior through elementProps.

In `@packages/chat/src/composer/root.tsx`:
- Around line 106-112: Update the useEffect that synchronizes requests with the
store so an empty requests array is normalized to null before
store.setRequests(), ensuring request mode is inactive when no requests exist;
preserve activation for non-empty requests.

In `@packages/chat/src/composer/store.ts`:
- Around line 206-208: Update the target validation logic around optionsHost so
non-editable targets outside this Composer are rejected instead of falling
through to true. Accept keyboard events only when the target belongs to this
editor, equals optionsElement, or matches the specific body-focus fallback
required by request mode; preserve the existing optionsHost ownership check.

In `@packages/chat/src/composer/types.ts`:
- Around line 11-16: Update ComposerRequestOption with a required distinct
option key, then propagate that key through the option actions and
compileRequests selection flow so selected options resolve by key rather than
label or value. Preserve the existing selected-value behavior after resolving
the correct option, and add coverage for duplicate labels and value/label
collisions.
