release: v3.0.0-beta.8

Previously, continuation hooks (todo-continuation, boulder-continuation, ralph-loop)
and background tasks resolved model info from filesystem cache, which could be stale
or missing. This caused session.prompt to fallback to default model (Sonnet) instead
of using the originally configured model (e.g., Opus).

Now all session.prompt calls first try API (session.messages) to get current model
info, with filesystem as fallback if API fails.

Affected files:
- todo-continuation-enforcer.ts
- sisyphus-orchestrator/index.ts
- ralph-loop/index.ts
- background-agent/manager.ts
- sisyphus-task/tools.ts
- hook-message-injector/index.ts (export ToolPermission type)

+**Priority**: Native providers (Claude/ChatGPT/Gemini) > GitHub Copilot > Free models
+
+##### Model Mappings
+
+When GitHub Copilot is enabled, oh-my-opencode uses these model assignments:
+
+| Agent         | Model                            |
+| ------------- | -------------------------------- |
+| **Sisyphus**  | `github-copilot/claude-opus-4.5` |
+| **Oracle**    | `github-copilot/gpt-5.2`         |
+| **Explore**   | `grok code` (default)            |
+| **Librarian** | `glm 4.7 free` (default)         |
+
+GitHub Copilot acts as a proxy provider, routing requests to underlying models based on your subscription.
+
+##### Setup
+
+Run the installer and select "Yes" for GitHub Copilot:
+
+```bash
+bunx oh-my-opencode install
+# Select your subscriptions (Claude, ChatGPT, Gemini)
+# When prompted: "Do you have a GitHub Copilot subscription?" → Select "Yes"
 ```
 
-##### Model Configuration
+Or use non-interactive mode:
 
-You'll also need full model settings in `opencode.json`.
-Read the [opencode-openai-codex-auth documentation](https://github.com/numman-ali/opencode-openai-codex-auth), copy provider/models config from [`config/opencode-modern.json`](https://github.com/numman-ali/opencode-openai-codex-auth/blob/main/config/opencode-modern.json) (for OpenCode v1.0.210+) or [`config/opencode-legacy.json`](https://github.com/numman-ali/opencode-openai-codex-auth/blob/main/config/opencode-legacy.json) (for older versions), and merge carefully to avoid breaking the user's existing setup.
+```bash
+bunx oh-my-opencode install --no-tui --claude=no --chatgpt=no --gemini=no --copilot=yes
+```
 
-**Available models**: `openai/gpt-5.2`, `openai/gpt-5.2-codex`, `openai/gpt-5.1-codex-max`, `openai/gpt-5.1-codex`, `openai/gpt-5.1-codex-mini`, `openai/gpt-5.1`
-
-**Variants** (OpenCode v1.0.210+): Use `--variant=<none|low|medium|high|xhigh>` for reasoning effort control.

+  return `### Frontend Files: VISUAL = HARD BLOCK (zero tolerance)
 
-Frontend files (.tsx, .jsx, .vue, .svelte, .css, etc.) require **classification before action**.
+**DEFAULT ASSUMPTION**: Any frontend file change is VISUAL until proven otherwise.
 
-#### Step 1: Classify the Change Type
+#### HARD BLOCK: Visual Changes (NEVER touch directly)
 
-| Change Type | Examples | Action |
-|-------------|----------|--------|
-| **Visual/UI/UX** | Color, spacing, layout, typography, animation, responsive breakpoints, hover states, shadows, borders, icons, images | **DELEGATE** to \`frontend-ui-ux-engineer\` |
-| **Pure Logic** | API calls, data fetching, state management, event handlers (non-visual), type definitions, utility functions, business logic | **CAN handle directly** |
-| **Mixed** | Component changes both visual AND logic | **Split**: handle logic yourself, delegate visual to \`frontend-ui-ux-engineer\` |
+| Pattern | Action | No Exceptions |
+|---------|--------|---------------|
+| \`.tsx\`, \`.jsx\` with styling | DELEGATE | Even "just add className" |
+| \`.vue\`, \`.svelte\` | DELEGATE | Even single prop change |
+| \`.css\`, \`.scss\`, \`.sass\`, \`.less\` | DELEGATE | Even color/margin tweak |
+| Any file with visual keywords | DELEGATE | See keyword list below |
 
-#### Step 2: Ask Yourself
+#### Keyword Detection (INSTANT DELEGATE)
 
-Before touching any frontend file, think:
-> "Is this change about **how it LOOKS** or **how it WORKS**?"
+If your change involves **ANY** of these keywords → **STOP. DELEGATE.**
 
-- **LOOKS** (colors, sizes, positions, animations) → DELEGATE
-- **WORKS** (data flow, API integration, state) → Handle directly
+\`\`\`
+style, className, tailwind, css, color, background, border, shadow,
+margin, padding, width, height, flex, grid, animation, transition,
+hover, responsive, font-size, font-weight, icon, svg, image, layout,
+position, display, opacity, z-index, transform, gradient, theme
+\`\`\`
 
-#### When in Doubt → DELEGATE if ANY of these keywords involved:
-style, className, tailwind, color, background, border, shadow, margin, padding, width, height, flex, grid, animation, transition, hover, responsive, font-size, icon, svg`
+**YOU CANNOT**:
+- "Just quickly fix this style"
+- "It's only one className"
+- "Too simple to delegate"
+
+#### EXCEPTION: Pure Logic Only
+
+You MAY handle directly **ONLY IF ALL** conditions are met:
+1. Change is **100% logic** (API, state, event handlers, types, utils)
+2. **Zero** visual keywords in your diff
+3. No styling, layout, or appearance changes whatsoever
+
+| Pure Logic Examples | Visual Examples (DELEGATE) |
+|---------------------|---------------------------|
+| Add onClick API call | Change button color |
+| Fix pagination logic | Add loading spinner animation |
+| Add form validation | Make modal responsive |
+| Update state management | Adjust spacing/margins |
+
+#### Mixed Changes → SPLIT
+
+If change has BOTH logic AND visual:
+1. Handle logic yourself
+2. DELEGATE visual part to \`frontend-ui-ux-engineer\`
+3. **Never** combine them into one edit`

+- Hardcoding paths (use `getClaudeConfigDir`, `getOpenCodeConfigDir`)
 - Using `JSON.parse` for user configs (always use `parseJsonc`)
 - Ignoring output size (large tool outputs MUST use `dynamicTruncate`)
-- Manual case conversion (use `toSnakeCase`, `normalizeToolName`)
+- Manual version parsing (use `opencode-version.ts` utilities)
+- Raw permission checks (use `permission-compat.ts`)

 ## LSP SPECIFICS
 - **Lifecycle**: Lazy initialization on first call; auto-shutdown on idle.
 - **Config**: Merges `opencode.json` and `oh-my-opencode.json`.
-- **Capability**: Supports full LSP spec including `codeAction/resolve` and `prepareRename`.
+- **Capability**: Supports full LSP spec including `rename` and `prepareRename`.
 
 ## AST-GREP SPECIFICS
 - **Precision**: Uses tree-sitter for structural matching (avoids regex pitfalls).
