-# Reapplication Plan — PRs Reverted by #11462
-
-> **Analysis date:** 2026-02-14
-> **Scope:** 42 PRs reverted by #11462 that were NOT reapplied by #11463
-> **Method:** Dry-run `git cherry-pick --no-commit` against `main-sync-rc6`

-## 1. Executive Summary
-
-| Category              | Count  | %     |
-| --------------------- | ------ | ----- |
-| **CLEAN_CHERRY_PICK** | 22     | 52 %  |
-| **MINOR_CONFLICTS**   | 9      | 21 %  |
-| **MAJOR_CONFLICTS**   | 6      | 14 %  |
-| **EXCLUDED (AI SDK)** | 5      | 12 %  |
-| **Total**             | **42** | 100 % |
-
-**Progress:** 37 of 42 PRs reapplied ✅. 5 PRs excluded (AI-SDK-dependent, will not be reapplied). Reapplication is complete.
-
-### Overall Assessment
-
-Over half (52 %) of the reverted PRs cherry-pick cleanly onto the current branch with zero conflicts. Another 21 % have only minor, mechanically-resolvable conflicts (lockfile diffs, adjacent-line shifts, small provider divergences). Together these 31 PRs have been reapplied across Batches 1 and 2.
-
-The remaining 6 PRs (all MAJOR conflicts) have been reapplied in PR [#11475](https://github.com/RooCodeInc/Roo-Code/pull/11475) after all product decisions were approved:
-
-- **Skills infrastructure** (#11102, #11157, #11414) — skills UI restored, then built-in skills mechanism removed as approved.
-- **Cross-cutting removals** (#11253, #11297, #11392) — provider removals, browser use removal, and Grounding checkbox removal all approved and applied.
-
-5 PRs have been permanently excluded because they depend on the AI SDK type system (see §8 Excluded PRs).
-
-### Key Risk Areas
-
-1. **`ClineProvider.ts` and `Task.ts`** are the most frequently touched files — sequential application within batches is essential.
-2. **Skills infrastructure** is the #1 conflict magnet across 3 PRs.
-3. **API provider files** (`gemini.ts`, `vertex.ts`, `bedrock.ts`) have diverged significantly.
-4. **i18n `settings.json`** files cause positional conflicts for any PR adding keys.
-5. **`pnpm-lock.yaml`** conflicts are trivially regeneratable via `pnpm install`.

-**Rationale:** These have zero conflicts and include the first 4 delegation PRs in the chain, which unblocks later batches.
-
-> **Post-application notes:**
->
-> - Extra fix commit: `maxReadFileLine` added to `ExtensionState` type for compatibility
-> - #11215 and #11410 were empty commits (changes already present in base)
-> - Verification: 5,359 backend tests ✅, 1,229 webview-ui tests ✅, TypeScript ✅

-## 5. Product Decisions Required
-
-The following 4 PRs perform **removals of existing functionality**. They cannot be reapplied without explicit stakeholder sign-off because the removal may conflict with current product direction or user expectations.
-
-### #11253 — Remove URL Context/Grounding Checkboxes
-
-- **What it removes:** URL context and Grounding search checkboxes from Gemini and Vertex providers
-- **Why sign-off is needed:** Grounding is a user-visible feature toggle. Removing it changes the Gemini/Vertex UX and may affect users relying on grounded responses. Product must confirm these features are deprecated.
-- **Conflict scope:** 4 files (gemini.ts, vertex.ts, and their spec files)
-- **Dependencies:** Should be applied after #11233 and #11303
-
-### #11297 — Remove 9 Low-Usage Providers
-
-- **What it removes:** 9 API provider integrations deemed low-usage
-- **Why sign-off is needed:** Removing providers breaks existing users of those providers. Product must confirm the usage data supports removal and that affected users have been notified or migrated.
-- **Conflict scope:** 18 files — 9 provider files are modify/delete conflicts (files were modified in HEAD but the PR deletes them), plus pnpm-lock.yaml, ApiOptions.tsx, package.json
-- **Dependencies:** None, but should be applied after all other provider-touching PRs
-
-### #11392 — Remove Browser Use Entirely
-
-- **What it removes:** The entire browser use feature (browser automation, mentions, tool definitions, UI toggles)
-- **Why sign-off is needed:** Browser use is a significant user-facing capability. Its removal is a major product decision affecting workflows that depend on browser automation. Product must confirm this feature is being sunset.
-- **Conflict scope:** 15 files — cross-cutting across Task.ts, ClineProvider.ts, system-prompt.spec.ts, mentions/, build-tools.ts, ChatView.tsx, SettingsView.tsx
-- **Dependencies:** None, but deeply cross-cutting
-
-### #11414 — Remove Built-In Skills Mechanism
-
-- **What it removes:** The built-in skills infrastructure (generation scripts, shared types, skill definitions)
-- **Why sign-off is needed:** This removes the mechanism for shipping skills bundled with the extension. Product must confirm that the skills system is moving entirely to user-managed skills (via SKILL.md files) and that no built-in skills are planned.
-- **Conflict scope:** 30 files — skills infrastructure files deleted in HEAD
-- **Dependencies:** Requires #11102 and #11157 to be applied first (skills UI must exist before it can be removed)

-> **Rationale:** The AI SDK migration is not being pursued. These PRs are tightly coupled to the AI SDK type system and cannot be cherry-picked or meaningfully adapted without that dependency. The earlier delegation chain (#11281 → #11302 → #11331 → #11335) is clean, already merged in Batch 1, and provides sufficient delegation support without these PRs.
