+# Robust Moderation & Test Improvements Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or the plan-runner to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Create a robust and fault-tolerant parsing mechanism for LLM moderation responses, implement image attachment capping/prioritization to prevent 400 Bad Request errors, fix floating-point/exponential Snowflake precision loss, and fix existing failing dev/streaming tests.
+
+**Architecture:**
+1. Improve parsing in `src/moderation/llmModerationClient.ts` to first try extracting JSON from Markdown blocks, then exhaustively scan start (`{`) and end (`}`) braces.
+2. Group, sort, and cap image attachments to at most 8 elements, prioritizing targets over context.
+3. Align existing failing tests in `tests/media/ytdlp.test.ts` and `tests/streaming/playTranscode.test.ts` to their runtime implementations.
+
+**Tech Stack:** TypeScript, Node.js, Vitest, Pino Logger

+
+### Task 1: Add Robust JSON Parsing and Capping to llmModerationClient
+
+**Files:**
+- Modify: `src/moderation/llmModerationClient.ts`
+- Test: `tests/moderation/llmModerationClient.test.ts`
+
+- [ ] **Step 1: Update parseModerationResponse and runModerationAnalysis**
+
+We will implement `extractJson` helper and update `parseModerationResponse` to use it. We will also sort and cap the image attachments in `runModerationAnalysis`.
+
+Modify `src/moderation/llmModerationClient.ts`:
+```typescript
+/**
+ * Helper to extract a JSON object from a potentially conversational or markdown-wrapped string.
+ * It first scans for markdown json code blocks, then falls back to trying all start/end brace pairs from largest to smallest.
+ */
+export function extractJson(content: string): any {
+ // 1. Try to find markdown json code blocks: ```json ... ``` or ``` ... ```
+ const codeBlockRegex = /```(?:json)?\s*([\s\S]*?)\s*```/g;
+ let match;
+ while ((match = codeBlockRegex.exec(content)) !== null) {
+ const codeContent = match[1].trim();
+ try {
+ const parsed = JSON.parse(codeContent);
+ if (parsed && typeof parsed === "object") {
+ return parsed;
+ }
+ } catch (e) {
+ // Continue to next code block
+ }
+ }
+
+ // 2. If no code blocks parse successfully, try scanning for {...} pairs
+ const openBraces: number[] = [];
+ const closeBraces: number[] = [];
+ for (let i = 0; i < content.length; i++) {
+ if (content[i] === "{") openBraces.push(i);
+ if (content[i] === "}") closeBraces.push(i);
+ }
+
+ // Try pairs from largest span to smallest
+ for (const start of openBraces) {
+ for (let j = closeBraces.length - 1; j >= 0; j--) {
+ const end = closeBraces[j];
+ if (end > start) {
+ const candidate = content.substring(start, end + 1);
+ try {
+ const parsed = JSON.parse(candidate);
+ if (parsed && typeof parsed === "object") {
+ return parsed;
+ }
+ } catch (e) {
+ // ignore and try next
+ }
+ }
+ }
+ }
+
+ throw new Error("No JSON object found in response");
+}
+```
+
+Replace the JSON parsing block inside `parseModerationResponse` with:
+```typescript
+ // Extract and parse JSON object
+ const parsed = extractJson(content);
+
+ // Validate structure
+ if (!parsed || typeof parsed !== "object" || !("results" in parsed)) {
+ throw new Error("Response missing 'results' array");
+ }
+```
+
+Update `runModerationAnalysis` image attachment sorting & capping:
+```typescript
+ // Check for image attachments to support multimodal analysis
+ const targetIdSet = new Set(targets.map((t) => t.id));
+ const imageAttachments = (attachments || [])
+ .filter(
+ (att) =>
+ (att.uploaded_url || att.discord_url) && att.type.startsWith("image/"),
+ )
+ .sort((a, b) => {
+ const aIsTarget = targetIdSet.has(a.message_id) ? 1 : 0;
+ const bIsTarget = targetIdSet.has(b.message_id) ? 1 : 0;
+ if (aIsTarget !== bIsTarget) {
+ return bIsTarget - aIsTarget; // Target messages first
+ }
+ return b.created_at - a.created_at; // Most recent first
+ })
+ .slice(0, 8); // Cap at 8 to prevent LLM API limits (e.g. Nemotron/Omni models 8-image limit)
+```
+
+- [ ] **Step 2: Run existing tests to verify they pass**
+
+Run: `pnpm run test tests/moderation/llmModerationClient.test.ts`
+Expected: PASS
+
+- [ ] **Step 3: Add new unit tests to verify robust JSON parsing and image capping**
+
+Add the following tests inside `describe("parseModerationResponse", ...)` in `tests/moderation/llmModerationClient.test.ts`:
+```typescript

+# Design Spec: Robust Moderation & Test Improvements
+
+**Date**: 2026-05-18
+**Topic**: Robust LLM Moderation Parsing, Capping Multimodal Attachments, and Fixing Dev/Streaming Tests
+
+---
+
+## 1. Goal & Context
+The project contains an LLM-based content moderation system that analyzes Discord messages and their image attachments. Real-world utilization revealed several issues:
+1. **Multimodal API Limits**: High numbers of image attachments in the target or surrounding context messages exceed API limits (e.g. Nemotron/Omni models cap at 8 images), triggering an HTTP 400 error.
+2. **LLM Output Variance**: LLM responses containing reasoning processes, conversational preambles, or markdown wrappers fail to parse under the current naive brace-matching algorithm, yielding `No JSON object found` or `Response missing 'results' array`.
+3. **Snowflake Precision Loss**: Snowflake IDs returned by the LLM sometimes suffer from floating-point rounding or formatting issues, preventing them from matching the original string-based target IDs.
+4. **Dev/Streaming Test Failures**: Failing tests in `ytdlp.test.ts` and `playTranscode.test.ts` due to mismatched parameters and type assertions.
+
+---
+
+## 2. Architecture & Detailed Design
+
+### A. Multimodal Attachment Filtering & Prioritization
+In `src/moderation/llmModerationClient.ts`:
+* Extract all image attachments.
+* Sort and prioritize attachments:
+ * Targets first: Attachments belonging to messages in the active `targets` list.
+ * Context second: Attachments belonging to context messages, sorted by `created_at` descending (most recent first).
+* Slice the resulting array to a maximum of **8 elements** to ensure we never hit model limits.
+* If the list is empty, proceed with the existing transparent 1x1 dummy PNG fallback.
+
+### B. Resilient JSON Extraction
+Implement `extractJson` inside `src/moderation/llmModerationClient.ts`:
+1. **Markdown Blocks**: Scan for code blocks using `/```(?:json)?\s*([\s\S]*?)\s*```/g`. Try to parse the first match yielding an object.
+2. **Exhaustive Span Search**: If markdown parsing fails, locate the indices of all `{` and `}` characters in the string. Try all matching pairs, starting from the largest span to the smallest.
+3. **Error Reporting**: If no candidate substring parses as an object, throw `No JSON object found in response`.
+
+### C. Message ID Fuzzy Mapping
+* Map `message_id` back to target IDs by stringifying and checking exact match.
+* If not matched and the ID ends with `"00"` or contains `"e+"` (indicating exponential format or floating point precision loss), search `targetIds` for a prefix match (first 10 characters) and restore the original ID.
+
+### D. Streaming & Dev Test Fixes
+* **`tests/media/ytdlp.test.ts`**: Update the assertion to expect `--format best[protocol^=http]/best` to match the actual production code.
+* **`tests/streaming/playTranscode.test.ts`**: Safely check if the input `readable` is an object and has the `.on` function before calling `readable.on("data", ...)`.
+
+---
+
+## 3. Test Plan & Expanded Coverage
+We will implement dedicated unit tests in `tests/moderation/llmModerationClient.test.ts`:
+1. **Image Capping & Prioritization**: Ensure image attachments are sorted correctly and capped at 8.
+2. **Complex Conversational Content**: Verify extraction from messages wrapped in markdown, with leading/trailing text, and multiple code blocks.
+3. **Reasoning Blocks**: Verify extraction when reasoning blocks contain separate `{` and `}` symbols.
+4. **Precision Loss Scenarios**: Verify automatic correction of floating-point string representations of Snowflake IDs.
+
+---
+
+## 4. Success Criteria
+* All tests pass successfully (`pnpm run test` exits with `0`).
+* System remains highly resilient to formatting variance in LLM responses.
+* No 400 Bad Request errors occur due to exceeding the maximum image attachment limit.
