The review item is correct. The previous head also folded multi-select (array) fields with their <id>__other companion. Once the client draft holds custom text it clears selections, so a multi-select answer of options plus free text (which OMP's askDialog accepts as selectedOptions + customInput) came back as text only, worse than main. This round narrows the fold to single-choice fields only (field.kind === "choice"). Multi-select fields go back to main's handling: two fields, both returned. The reported bug (single-choice OMP questions showing 2N steps with no question text) stays fixed. Folding is still one Map lookup per field, O(fields), and no regex was added. I extended the existing repro test with a multi-select form; it checks that content({q0:['Postgres'], q0__other:'SQLite'}) returns both. It fails on 6cab423 and passes now.

Fixes #27053

Reproduction on main

Commit 6ba3de7 (origin/main). Started a fresh dev server (T3CODE_DEV_SEED=0 vp run dev) and added an acpRegistry provider instance with source 'local' whose command is a small scripted ACP agent. That agent answers initialize/session/new and, on session/prompt, sends the exact elicitation/create form OMP 18.19.0's askDialog (src/modes/acp/acp-agent.ts) builds for a two-question ask: message 'Answer 2 questions', properties q0 {type string, title , description

, oneOf options}, q0__other {type string, title 'Other (type your own)'}, the same again for q1. Started a thread on it with t3 thread start and opened it in the web client. The pending-question panel showed '1/4' with the first question and its options. After clicking 'Postgres', step '2/4' showed header 'Other (type your own)' and body 'Answer 2 questions', with no question text: the reporter's screenshot exactly. Two questions show as four steps. A failing unit test in packages/provider-acp/src/server/elicitationForm.test.ts (branch factory/repro-27053) feeds the same form to parseElicitationForm and gets 4 questions, two of them with no question text, where 2 questions are expected.

Evidence

On each commit, start the real web app with fresh synthetic state, replay OMP's two-question elicitation form, open the pending panel, and click Postgres. Chromium, 1280×800, light theme. Stills show the composer crop; recordings show the full viewport.

Not shown:

• The actual OMP executable was not run; the replay agent emitted its specified elicitation form through the real ACP adapter.
• Answer submission serialization and multi-select companion handling were not exercised; this proof covers the reported single-choice panel rendering and navigation.

Tests

vp test run src/server/elicitationForm.test.ts (packages/provider-acp): 7/7 pass. With the parser change reverted to 6cab423 the new multi-select assertion fails (1 failed | 6 passed). vp run check:changed: format, lint, knip, typecheck (14 packages) and tests (2 files, 9 tests) all pass.

Not in this change

• OMP puts the question in the schema's title and the short header in description, so the panel's header line shows the question and the body shows the header (e.g. 'Database'). This was true of the first step before the fix too; swapping them would be a separate presentation change.
• When a choice is answered with attachments, intake appends attachment references to the answer; for an OMP question that answer no longer matches an option and is sent as companion free text (Droid's flavor maps it back to the option label). Not part of this bug.
• Long pending-question text overflows its container in the composer #27051 (long question text overflowing the same row) is a separate issue.
• OMP multi-select questions still show as two steps (choices, then 'Other (type your own)'), as on main. Folding them needs the client draft to keep selections alongside custom text, which is a change to the shared web/mobile answer handling.
• OMP puts the question in the schema's title and the short header in description, so the header line shows the question; unchanged from main.

Approvability

Verdict: Approved at 12eded7

Macroscope's review found this PR approvable — ACP forms now present an optional choice and its free-text companion as one question, routing custom answers back to the companion field. The change is narrowly scoped and preserves separate required-field and multi-select behavior.

Walkthrough

The elicitation parser combines eligible optional single-choice fields and their optional text companions into one question. It maps valid choice answers to the choice field and free-text answers to the companion field. Tests cover these mappings and multi-select answers.

Changes: Elicitation choice companions

Layer / File(s)	Summary
Collect and pair eligible fields packages/provider-acp/src/server/elicitationForm.ts	The parser collects schema fields before building questions. It pairs optional single-choice fields with optional text fields named <id>__other.
Build questions and convert answers packages/provider-acp/src/server/elicitationForm.ts, packages/provider-acp/src/server/elicitationForm.test.ts	The parser omits paired companions from displayed questions. It maps valid choice answers to the choice ID and free-text answers to the companion ID. Tests cover these cases and multi-select answers.

Full details: Title check

Explanation

The title names the fix (ACP ask forms with a free-text companion field), but it does not match the changeset. The change folds only single-choice fields with their companion text field into one question. The PR title describes the behavior instead of the change, and it is a long, 79-character single line. The title is related to the main change, so it passes.

Full details: Out of Scope Changes check

Explanation

The reviewed changes touch only elicitationForm.ts and elicitationForm.test.ts in packages/provider-acp. The parser change folds single-choice <id>__other companions into their choice question. It keeps multi-select fields separate and adds no presentation, attachment, or web client changes. The test extension covers the single-choice fold and the multi-select retention path, both tied to the reported bug and the stated multi-select behavior. No unrelated change was found in the inspected diff.

Full details: Description check

Explanation

The description follows the template's main sections and gives a substantive account of the change. It states the problem and reproduction on main, the fix (folding single-choice fields with their optional __other companion, multi-select excluded), and verification (a unit test that fails on 6cab423 and passes now, plus a 7/7 test run and a check:changed run). It includes before/after evidence and an explicit list of what was not checked. Gaps: the Scope section does not explicitly link the issue as a bug report in the required form beyond 'Fixes #27053', and it does not state why no issue is needed (an issue is linked, so this is minor). The description also contains a long repeated note about header/question presentation, and it does not say which model and harness did the work, which the template asks for when an agent was used. These gaps are non-critical, so the check passes.

Full details: Linked Issues check

Explanation

Issue #27053 has two coding expectations: (1) the question prompt is always shown, and (2) the counter clearly says whether it counts questions or options. The diff against 6ba3de7 changes only packages/provider-acp/src/server/elicitationForm.ts and its test. Folding <id>__other into single-choice questions removes the extra free-text step. For the two-question OMP form, the parser now returns 2 questions, not 4, so the reported 2N-step symptom is addressed at the parser level, and the question text is no longer lost to a companion step. The parser change does not alter the counter label or any rendering of the counter. The PR objectives state that counter wording is not changed. Requirement (2) is therefore not implemented by this PR. Scope note: the web client counter code was not inspected. The absence of a counter change rests on the PR description and the two-file diff.

Resolution

Either implement the counter requirement in this PR, for example by labeling the counter so it states what it counts (questions or options) in the pending-question panel, or ask the issue author to confirm that the counter requirement is satisfied by the question count now matching the form and to split the remaining counter wording into a separate issue. Add a test or a rendering check for the chosen counter label.
