improvements to builder and opencode cli.txt

@@ -0,0 +1,183 @@
+ ## 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
