+## Why
+A recent feature request highlighted that users struggle to scope proposals when all clarifications have to be typed manually. They want a guided interview that surfaces missing assumptions, recommends best-practice defaults, and produces a sharper brief before handing off to `/openspec/proposal`. Delivering an interactive Q&A flow keeps OpenSpec competitive with other planning assistants and shortens the loop between idea and actionable change specification.
+
+## What Changes
+- Add a dedicated `/openspec/proposal-qa` slash command that runs a structured discovery interview before drafting a change proposal.
+- Teach the agent to analyse the initial request, label what is already explicit versus ambiguous, and derive a small set of high-impact clarifying questions.
+- Require every question to include rationale, 2–4 recommended options with a default, and clear guidance on when to pick each option.
+- Capture the conversation outcome in a structured summary (problem, clarified decisions, open risks) that the user can accept or tweak before invoking `/openspec/proposal`.
+- Update onboarding (`init`/`update`) and slash command templates so the new command ships everywhere OpenSpec currently provisions proposal/apply/archive helpers.
+
+## Impact
+- Affected specs: assistant-proposal-qa (new), cli-init, cli-update, slash-commands-template (if modelled separately)
+- Affected code: `src/core/templates/slash-command-templates.ts`, `src/core/configurators/slash/*`, command scaffolding that writes `.claude/.cursor/.opencode` files, and associated tests.

+# assistant-proposal-qa Specification
+
+## ADDED Requirements
+### Requirement: Interactive Proposal Q&A Command
+
+The system SHALL provide a `/openspec/proposal-qa` slash command that prepares users for `/openspec/proposal` by running a structured discovery interview.
+
+#### Scenario: Launching the proposal interview
+- **WHEN** the user runs `/openspec/proposal-qa Build a notifications digest`
+- **THEN** acknowledge the request and restate the draft problem statement
+- **AND** highlight what parts of the request are already concrete versus ambiguous (e.g., "Strong signals" and "Needs clarity")
+- **AND** outline the upcoming steps: targeted questions followed by a summary hand-off.
+
+#### Scenario: Honour non-interactive environments
+- **GIVEN** slash commands are invoked in a non-interactive environment (e.g., automation requesting defaults)
+- **WHEN** `/openspec/proposal-qa` is triggered with `--no-interactive`
+- **THEN** skip the question loop
+- **AND** produce a summary that records the request, recommended defaults, and instructions for editing manually before running `/openspec/proposal`.
+
+### Requirement: Targeted Clarifying Questions
+
+The interview SHALL adaptively surface 3–6 high-leverage questions that eliminate ambiguity in the proposal brief.
+
+#### Scenario: Ask one question at a time with rationale
+- **WHEN** the interview begins gathering answers
+- **THEN** select the next most risky/vague aspect of the feature
+- **AND** present a single question that includes:
+  - A short rationale explaining why the question matters for the proposal
+  - 2–4 recommended options formatted as a bulleted list with `**Default**` clearly marked
+  - Guidance for when to choose each option (one sentence per option)
+- **AND** wait for the user response (or `default`/`skip`) before showing another question.
+
+#### Scenario: Provide fallbacks when users defer
+- **WHEN** the user replies with `idk`, `default`, or leaves the answer empty
+- **THEN** accept the default option for that question
+- **AND** note in the transcript that the default was applied.
+
+#### Scenario: Capture bespoke answers
+- **WHEN** the user supplies an answer that does not match any recommended option
+- **THEN** accept the custom answer
+- **AND** record a short interpretation describing how it will shape the proposal.
+
+### Requirement: Synthesis and Handoff
+
+The interview SHALL produce an actionable summary that readies the agent to draft the formal change proposal.
+
+#### Scenario: Summarise discoveries before exit
+- **WHEN** the question loop completes (or is skipped)
+- **THEN** output a structured summary containing:
+  - Problem statement and scope recap
+  - Table or bullet list of decisions (question → final answer → reasoning/default flag)
+  - Noted risks, open questions, and assumptions to confirm in the proposal
+- **AND** recommend next actions: either ask for revisions, run `/openspec/proposal` with this summary, or request further research.
+
+#### Scenario: Provide reusable prompt snippet
+- **WHEN** the summary is generated
+- **THEN** include a copyable prompt block that the user can paste into `/openspec/proposal`
+- **AND** ensure the prompt references the summary decisions and flags any open items for follow-up.
+
+#### Scenario: Allow re-entry for more questions
+- **WHEN** the user indicates they want to refine further (e.g., "ask more" or "another pass")
+- **THEN** identify remaining ambiguous areas not yet questioned
+- **AND** continue with additional questions (up to the 6-question cap) before regenerating the summary.

+### Requirement: Slash Command Configuration
+The init command SHALL generate slash command files for supported editors using shared templates, including the interactive proposal interview instructions.

+## Why
+Recent cross-shell regressions for `openspec` commands revealed that our existing unit/integration tests do not exercise the packaged CLI or shell-specific behavior. The prior attempt at Vitest spawn tests stalled because it coupled e2e coverage with `pnpm pack` installs, which fail in network-restricted environments. With those findings incorporated, we now need an approved plan to realign the work.
+
+## What Changes
+- Adopt a phased strategy that first stabilizes direct spawn testing of the built CLI (`node dist/cli/index.js`) using lightweight fixtures and a shared `runCLI` helper.
+- Expand coverage once the spawn harness is stable, keeping the initial matrix focused on bash jobs for Linux/macOS and `pwsh` on Windows while exercising both the direct `node dist/cli/index.js` invocation and the bin shim with non-TTY defaults and captured diagnostics.
+- Treat packaging/install validation as an optional CI safeguard: when a runner has registry access, run a simple pnpm-based pack→install→smoke-test flow; otherwise document it as out of scope while closing remaining hardening items.
+- Close out the remaining cross-shell hardening items: ensure `.gitattributes` covers packaged assets, enforce executable bits for CLI shims during CI, and finish the pending SIGINT handling improvements.
+
+## Impact
+- Tests: add `test/cli-e2e` spawn suite, create the shared `runCLI` helper, and adjust `vitest.setup.ts` as needed.
+- Tooling: update GitHub Actions workflows with the lightweight matrix above and (optionally) a packaging install check where network is available.
+- Docs: note phase progress and any limitations inline in this proposal (or the relevant spec) so future phases have clear context.
+
+### Phase 1 Status
+- Shared `test/helpers/run-cli.ts` guarantees the CLI bundle exists before spawning and enforces non-TTY defaults for every invocation.
+- New `test/cli-e2e/basic.test.ts` covers `--help`, `--version`, a successful `validate --all --json`, and an unknown-item error path against the `tmp-init` fixture copy.
+- Legacy top-level `validate` exec tests now rely on `runCLI`, avoiding manual `execSync` usage while keeping their fixture authoring intact.
+- CI matrix groundwork is in place (bash on Linux/macOS, pwsh on Windows) so the spawn suite runs the same way the helper does across supported shells.
