+# OC-100 Request Type UX
+
+## Goal
+
+Make request type management obvious and deliberate in Missio's UI. Users should be able to choose the request type when creating a request, see the current type while editing, and convert between compatible request types without corrupting schema data.
+
+## Product Benchmark
+
+Review current request-type workflows in industry-standard REST/API clients before implementation:
+
+| Tool | UX Pattern To Inspect |
+| --- | --- |
+| Bruno | Request creation flow, request type/protocol labels, GraphQL/gRPC/WebSocket affordances, and whether type changes are supported after creation. |
+| Postman | New request protocol picker, type labels in tabs/sidebar, request conversion behavior, and guardrails when switching protocols with incompatible fields. |
+| Missio current state | Command palette/tree context creation, request editor header, YAML fallback, and how `type: http`, `type: graphql`, `type: websocket`, and `type: grpc` are represented. |
+
+Record the benchmark findings in `AGENT_PROGRESS.md` before implementation. Prefer patterns that are familiar to users of Bruno/Postman, but keep Missio aligned with the OpenCollection schema rather than copying product-specific data models.
+
+## Current Gap
+
+| Surface | Gap |
+| --- | --- |
+| New request | Users cannot choose `http`, `graphql`, `websocket`, or `grpc` from the UI when creating a request. |
+| Editor header | The current request type is not prominent or editable in the visual editor. |
+| Type switching | There is no guided way to change request type, even when common fields such as name, URL, headers, auth, variables, runtime, and settings can be preserved. |
+| Data safety | Switching between incompatible protocols needs explicit confirmation and a preview of fields that will be preserved, transformed, or dropped. |
+| Tree/context actions | Context menus do not expose protocol-specific creation commands at collection/folder scope. |
+| Tests | Existing protocol tests prove execution/editor behavior, but not request-type creation or conversion UX. |
+
+## Implementation Plan
+
+1. Audit the current UI entry points:
+
+| Entry Point | Work |
+| --- | --- |
+| Command palette | Find `newRequest` and related command handlers. |
+| Tree context menu | Find folder/collection context commands and menu contribution points. |
+| Request editor | Find the visual editor header and protocol-specific panels. |
+| YAML fallback | Confirm manual `type:` edits remain supported and validated. |
+
+2. Design the request type UX:
+
+| Need | Expected Behavior |
+| --- | --- |
+| Creation | User selects HTTP, GraphQL, WebSocket, or gRPC before the starter YAML is written. |
+| Current type | Editor shows a clear protocol/type control near the request title or primary request controls. |
+| Switching | Type control offers compatible conversions and marks destructive conversions with confirmation. |
+| Preservation preview | Conversion explains preserved, transformed, and removed fields before applying. |
+| Defaults | New templates use realistic schema-valid defaults and line up with demo requests. |
+
+3. Implement schema-aware conversion:
+
+| Source/Target | Minimum Preservation |
+| --- | --- |
+| HTTP to GraphQL | Name, URL, method where relevant, headers, auth, params, variables, runtime, settings. |
+| GraphQL to HTTP | Name, URL, method, headers, auth, params, variables, runtime, settings; GraphQL query/variables become a safe body representation only with user confirmation. |
+| HTTP/GraphQL to WebSocket | Name, URL where compatible, headers, auth, variables, runtime, settings. |
+| HTTP/GraphQL to gRPC | Name, auth, variables, runtime, settings; URL/metadata preserved only when semantically valid. |
+| WebSocket/gRPC to other protocols | Preserve shared schema fields and require confirmation for protocol-specific message/method/proto data loss. |
+
+4. Add guardrails:
+
+| Guardrail | Behavior |
+| --- | --- |
+| Non-destructive default | Do not discard protocol-specific fields without explicit confirmation. |
+| YAML round-trip | Unknown but schema-valid fields must survive no-op edits and safe conversions. |
+| Validation | Converted requests validate against the selected type's schema before saving. |
+| Undo | Conversion should be a normal editor/workspace edit that users can undo. |
+
+5. Add tests and docs:
+
+| Area | Coverage |
+| --- | --- |
+| Command/service unit tests | Creation templates and conversion helpers for all supported request types. |
+| Editor/webview tests | Type selector rendering, conversion confirmation messaging, and save payloads. |
+| Round-trip tests | Converted requests preserve shared fields and do not leak old protocol roots. |
+| Regression tests | Existing HTTP, GraphQL, WebSocket, and gRPC fixtures still load, edit, validate, and execute. |
+| User docs | Briefly document how to create and switch request types, including destructive conversion warnings. |
+
+## Acceptance Criteria
+
+| Requirement | Acceptance |
+| --- | --- |
+| Protocol creation | UI can create schema-valid HTTP, GraphQL, WebSocket, and gRPC requests. |
+| Type visibility | Visual editor makes the current request type obvious without requiring YAML inspection. |
+| Safe switching | Users can switch request type with clear preservation/loss preview and confirmation for destructive conversions. |
+| Schema alignment | Saved YAML uses the OpenCollection `type:` field and protocol-specific roots correctly. |
+| Industry alignment | Progress log records Bruno/Postman UX observations and the resulting Missio decisions. |
+| Tests | Complete automated tests cover creation, conversion, validation, round-trip preservation, and regressions for existing protocol fixtures. |
+
+## Out Of Scope

+| Area | Reason |

+| Import/export/snippet protocol polish | Covered by OC-070. |
