+ ## Background
+ The Plugin Compass builder is public-facing and currently exposes OpenCode-specific error messages and codes to end users. This is confusing and leaks
+ internal detail. Additionally, fallback behavior mixes client and server responsibilities in a way that can trigger the wrong recovery action (e.g.,
+ switching models when a malformed edit should trigger a “continue”). Provider rate limits are configured in the admin panel, but the runtime behavior
+ should distinguish between minute limits (wait and retry) vs. hour/day limits (skip to next model). Finally, the OpenCode CLI must reliably include
+ WordPress validation instructions and ensure the WordPress validator tool is actually callable, while preserving token extraction to keep usage accurate.
+
+ ## Goals
+ 1. **Public UX**: Replace builder error messaging with a safe, branded message.
+ 2. **Fallback correctness**:
+ - Malformed edits → send “continue” to OpenCode (same model/session).
+ - Provider/quota errors → switch to next model/provider.
+ 3. **Rate-limit behavior**:
+ - Minute limits → wait until reset, then retry same provider/model.
+ - Hour/day limits → skip immediately to next model.
+ - Automatically return to a provider once limits lift.
+ 4. **WordPress validation**:
+ - Ensure `wordpress-plugin.txt` prompt is always applied in builder sessions.
+ - Ensure `wordpress-validator:validate_wordpress_plugin` is callable.
+ 5. **Token extraction safety**: Errors/continuations should not break token usage reporting in the builder UI.
+
+ ## Non-Goals
+ - Changing plan models or public model list behavior.
+ - Redesigning the builder UI or admin UI.
+ - Modifying export/ZIP workflows.
+
+ ---
+
+ ## Current State Summary (from repo)
+ - Builder UI is in `chat/public/builder.js` and `chat/public/builder.html`.
+ - Fallback logic for OpenCode is primarily in `chat/server.js`:
+ - `sendToOpencodeWithFallback`
+ - `isEarlyTerminationError`
+ - `classifyProviderError`
+ - `isProviderLimited`
+ - WordPress prompt file exists at:
+ - `opencode/packages/opencode/src/session/prompt/wordpress-plugin.txt`
+ - WordPress validator tool exists as a built-in tool:
+ - `opencode/packages/opencode/src/tool/validate-wordpress-plugin.ts`
+ - MCP server for WP CLI testing is already wired in `chat/server.js`.
+
+ ---
+
+ ## Plan
+
+ ### 1) Builder Error Masking (Public UI)
+ **Files**: `chat/public/builder.js`
+
+ **Changes**
+ - When rendering assistant errors, replace any OpenCode or provider error text with:
+ - **“Plugin Compass failed. Please try again.”**
+ - Apply the same masking to `setStatus()` paths for OpenCode errors in builder UI.
+
+ **Acceptance Criteria**
+ - Builder page never shows “OpenCode failed” or raw exit codes.
+ - Admin/internal logs remain unchanged.
+
+ ---
+
+ ### 2) Malformed Edit → Continue (OpenCode)
+ **Files**: `chat/server.js`
+
+ **Changes**
+ - Extend `isEarlyTerminationError()` to treat malformed edit cases as early termination:
+ - Add patterns like `/error:.*malformed edit/i` and `/error:.*invalid edit/i`.
+ - This ensures `sendToOpencodeWithFallback` issues a `[CONTINUE]` retry in the same model/session before switching.
+
+ **Acceptance Criteria**
+ - Malformed edit errors trigger a “continue” attempt.
+ - Only after `MAX_CONTINUE_ATTEMPTS` does it switch models.
+
+ ---
+
+ ### 3) Provider Errors → Switch Model
+ **Files**: `chat/server.js`
+
+ **Changes**
+ - Expand `classifyProviderError()` to detect provider quota/billing messages:
+ - “key limit reached”, “quota exceeded”, “insufficient quota”, “payment required”, etc.
+ - Return `{ action: 'switch' }` for these errors.
+
+ **Acceptance Criteria**
+ - Quota/billing errors cause immediate fallback to next model/provider.
+
+ ---
+
+ ### 4) Rate Limits: Minute vs Hour/Day
+ **Files**: `chat/server.js`
+
+ **Changes**
+ - Extend `isProviderLimited()` to return `retryAfterMs` when the limit field is per-minute.
+ - In `sendToOpencodeWithFallback`:
+ - If the limit is **minute-based**, wait for reset and retry the same provider/model.
+ - If **hour/day**, skip immediately to next model.
+ - Use provider usage timestamps to compute `retryAfterMs`.
+
+ **Acceptance Criteria**
+ - Minute limit → waits until reset, retries same model.
+ - Hour/day limit → switches to next model without waiting.
+ - When a provider’s limit clears, it is retried in chain order.
+
+ ---
+
+ ### 5) WordPress Validator MCP + Prompt Enforcement
+ **Files**
+ - `opencode/mcp-servers/wordpress-validator/*` (new)
+ - `chat/server.js`
+ - `opencode/packages/opencode/src/session/prompt/wordpress-plugin.txt`
+ - `opencode/packages/opencode/src/session/system.ts`
+
+ **Changes**
+ 1. **MCP Server**
+ - Create `wordpress-validator` MCP server wrapping the same validation script.
+ - Tool name: `validate_wordpress_plugin`.
+ 2. **Wire MCP server for builder**
+ - Use `OPENCODE_EXTRA_MCP_SERVERS` in `chat/server.js` to enable this MCP server for builder sessions.
+ 3. **Prompt update**
+ - Update `wordpress-plugin.txt` to reference both:
+ - `wordpress-validator:validate_wordpress_plugin` (MCP)
+ - `validate_wordpress_plugin` (built-in)
+ 4. **Force WordPress prompts**
+ - Add `OPENCODE_FORCE_WORDPRESS=1` option in `system.ts` to always append WordPress prompts for builder sessions.
+ - Set this env var when running OpenCode from the builder.
+
+ **Acceptance Criteria**
+ - WordPress validator tool is callable and not blocked by tool registry.
+ - WordPress prompt always included for builder sessions.
+
+ ---
+
+ ### 6) Token Extraction & Usage Safety
+ **Files**: `chat/server.js`, `chat/public/builder.js`
+
+ **Changes**
+ - Ensure token usage is recorded on:
+ - Successful completion
+ - Continuations
+ - Error states with estimated tokens
+ - Ensure builder calls `loadUsageSummary()` after completion/error even if SSE fails.
+
+ **Acceptance Criteria**
+ - Usage meter updates after errors and continuations.
+ - No “missing token usage” regressions in builder.
+
+ ---
+
+ ## Public API / Interface Changes
+ - New env flag:
+ - `OPENCODE_FORCE_WORDPRESS=1`
+ - New MCP server:
+ - `wordpress-validator` (exposed through `OPENCODE_EXTRA_MCP_SERVERS`)
+
+ ---
+
+ ## Testing & Validation
+
+ 2. Malformed edit → continue attempt occurs before model switch.
+ 3. Provider minute limit → waits until reset then retries same model.
+ 4. Provider hour/day limit → switches immediately.
+ 5. Validator MCP tool works; WordPress prompt is applied.
+
+ ---
+
+ ## Risks / Mitigations
+ - **Risk**: Overeager fallback if error matching is too broad.
+ - Mitigation: Keep strict patterns and prefer explicit error prefixes.
+ - **Risk**: Waiting too long on minute limits.
+ - Mitigation: Compute retry after using usage timestamps and cap to 60s.
+
+ ---
+
+ ## Assumptions
+ - Builder runs in the chat server context using OpenCode CLI.
+ - Admin limits are authoritative for provider restrictions.
+ - WordPress validator script exists at `scripts/validate-wordpress-plugin.sh`.
+
+ ---
+
+ ## Milestones
+ 1. Builder error masking
+ 2. Fallback and limit corrections
+ 3. MCP server + prompt enforcement
+ 4. Validation + testing
