Daily Morning Brief - Convex Deployment Fix

Fixed December 11, 2025 - Resolved Convex deployment error caused by query function in Node.js action file.

Issue

Convex deployment failed with error:

`getFeedItemsForMetrics` defined in `domains/research/dashboardMetrics.js` is a Query function.
Only actions can be defined in Node.js.

Root Cause

• getFeedItemsForMetrics was an internalQuery defined in dashboardMetrics.ts
• dashboardMetrics.ts uses "use node" directive for actions that need Node.js runtime
• Convex platform constraint: Queries cannot use Node.js runtime - only actions can

Solution

1. Moved query to correct file:

   • From: convex/domains/research/dashboardMetrics.ts (has "use node")
   • To: convex/domains/research/dashboardQueries.ts (no "use node")

2. Updated reference:

   // Before:
   await ctx.runQuery(internal.domains.research.dashboardMetrics.getFeedItemsForMetrics)
   
   // After:
   await ctx.runQuery(internal.domains.research.dashboardQueries.getFeedItemsForMetrics)
   

3. Cleaned up imports:

   • Removed internalQuery import from dashboardMetrics.ts

Commit: 5d52916

Root Cause: The overflow-hidden class on the main dashboard container prevented tooltips from rendering outside bounds.

Solution:

• File: src/features/research/components/StickyDashboard.tsx (Line 48)
• Change: Removed overflow-hidden class and added z-10 for proper stacking context

// Before:
<div className="sticky top-4 rounded-xl border border-slate-200 bg-white shadow-sm overflow-hidden p-3 ...">

// After:
<div className="sticky top-4 z-10 rounded-xl border border-slate-200 bg-white shadow-sm p-3 ...">

2. Invisible Chart Line

Problem: The line chart's primary trend line was not visible on the page despite data being present.

Root Cause: SVG <path> elements don't understand Tailwind's text-* utility classes for stroke colors. The colorStyle function was returning stroke: undefined and relying on className, which only works for HTML text elements.

Solution:

• File: src/features/research/components/InteractiveLineChart.tsx

• Changes:

  1. Fixed colorStyle function (Lines 20-29) to return actual hex color values:

  // Before: Returned undefined stroke values
  if (series.color === "accent") return { className: "text-indigo-600", stroke: undefined, fill: undefined };
  
  // After: Returns actual hex colors for SVG rendering
  if (series.color === "accent") return { className: "text-indigo-600", stroke: "#4f46e5", fill: "#4f46e5" };
  if (series.color === "gray") return { className: "text-slate-400", stroke: "#94a3b8", fill: "#94a3b8" };
  if (series.color === "black") return { className: "text-slate-900", stroke: "#0f172a", fill: "#0f172a" };
  return { className: series.color ? series.color : "text-slate-800", stroke: "#1e293b", fill: "#1e293b" };
  

  2. Added SVG viewBox padding (Line 236) to prevent edge clipping:

  // Before:
  <svg viewBox={`0 0 ${width} ${height}`} className="w-full h-full overflow-visible">
  
  // After:
  <svg viewBox={`-10 -10 ${width + 20} ${height + 20}`} className="w-full h-full overflow-visible">
  

Technical Details

Key Insight: SVG elements require actual color values (hex codes like #4f46e5) for stroke and fill attributes. Tailwind utility classes like text-indigo-600 only apply to HTML text elements via CSS, not SVG presentation attributes.

Verification:

• ✅ Build compiles with no TypeScript errors
• ✅ Chart line renders with proper indigo color (#4f46e5)
• ✅ Tooltips appear without clipping at container edges
• ✅ No console errors or warnings
• ✅ Hover interactions work smoothly

Files Modified

• src/features/research/components/StickyDashboard.tsx - Removed overflow-hidden, added z-10
• src/features/research/components/InteractiveLineChart.tsx - Fixed SVG color rendering and viewBox padding

Inspired by Microsoft AutoGen's Teachability, agents can now learn and persist knowledge:

• Facts - User name, company, role, tools, preferences
• Preferences - Tone, format, brevity, communication style
• Skills - User-defined workflows triggered by phrases

Architecture

• convex/tools/teachability/teachingAnalyzer.ts - LLM-based extraction of teachable content
• convex/tools/teachability/userMemoryTools.ts - Vector search and skill trigger matching
• convex/tools/teachability/learnUserSkill.ts - Explicit skill learning tool
• convex/domains/teachability/ - Public API for Settings UI
• convex/schema.ts - userTeachings table with vector index

How It Works

1. Inference: After each response, background analyzer detects facts/preferences/skills
2. Storage: Teachings stored with embeddings for semantic retrieval
3. Injection: Context handler loads relevant memories before each response
4. Skills: Trigger phrases activate learned procedures automatically
5. UI: Settings panel shows saved preferences and skills for editing

LLM Model Registry

• Location: shared/llm/modelCatalog.ts
• Purpose: single source of truth for provider/task defaults (OpenAI → gpt-5-nano/mini reasoning models; Gemini → 2.5 flash/pro and image/flash-lite variants; 3-pro preview as fallback)
• Helper: getLlmModel(task, provider?, override?) returns the preferred model while honoring explicit overrides
• Tasks covered: chat, agent, router, judge, analysis, vision, fileSearch, voice
• Usage: import getLlmModel and pass to OpenAI or Gemini SDK calls instead of hardcoding model strings
• Note: gpt-5-nano/mini are reasoning models that only support the default temperature (1). Do not pass custom temperature values when using these models.
• Key call sites wired to the registry (examples): convex/actions/externalOrchestrator.ts (chat proxy), convex/router.ts (streaming), convex/domains/agents/fastAgentPanelStreaming.ts (panel chat + doc generation), convex/domains/agents/fastAgentChat.ts (modern chat), convex/domains/verification/claimVerificationAction.ts (judge), convex/tags_actions.ts (tagging), convex/domains/documents/fileAnalysis.ts and convex/domains/ai/genai.ts (Gemini analysis/extraction), convex/domains/documents/fileSearch.ts (Gemini file search), convex/domains/ai/morningDigest.ts (digest summary), convex/domains/integrations/voice/voiceActions.ts (voice), convex/tools/integration/orchestrationTools.ts, convex/tools/document/contextTools.ts, convex/tools/calendar/recentEventSearch.ts, convex/tools/media/recentNewsSearch.ts, convex/tools/integration/peopleProfileSearch.ts, convex/tools/sec/secCompanySearch.ts, and convex/tools/evaluation/evaluator.ts.

Architecture

Multi-Agent System

The platform uses a hierarchical multi-agent architecture:

• Coordinator Agent - Routes queries to specialized agents
• Simple Chat Agent - Fast responses for greetings and simple questions
• Web Agent - Web search using LinkUp API
• Document Agent - Search and analyze internal documents
• Media Agent - Find videos and media content
• SEC Agent - Research SEC filings and financial data
• Entity Research Agent - Deep research on companies and people

Agent Composition

Agents can delegate to other agents using three patterns:

1. Single Delegation - One parent → one sub-agent
2. Parallel Delegation - One parent → multiple sub-agents simultaneously
3. Sequential Delegation - One parent → chain of sub-agents (pipeline)

Safety Features:

• Maximum delegation depth: 3 levels
• Timeout per sub-agent: 60 seconds
• Graceful error handling

Human-in-the-Loop

Agents can request clarification from users when queries are ambiguous:

1. Agent calls askHuman tool with question and optional quick-select options
2. System creates pending request in database
3. UI displays request card in Fast Agent Panel or Mini Note Agent
4. User responds via quick-select or free-form text
5. System validates authorization and continues agent execution

Security Features:

• User ID validation on all mutations
• Authorization checks (users can only respond to their own requests)
• Authentication required for all operations

Deep Agents 2.0 Architecture

The platform implements a frontier-grade deep research agent architecture with the following components:

Core Components

4 Code-Enforced Invariants

The architecture guarantees these invariants in code, not just prompts:

Invariant A: Message Isolation

• Every user message gets a unique messageId
• Tools refuse to mutate state if messageId doesn't match
• Prevents cross-query contamination

Invariant B: Safe Context Fallback

• compactContext only falls back to previous context if same messageId
• Never resurrects old data from previous messages
• All output stamped with messageId

Invariant C: Memory Deduplication

• memoryUpdatedEntities array tracks what was updated
• isMemoryUpdated / markMemoryUpdated tools for explicit tracking
• Prevents duplicate fact insertions

Invariant D: Capability Version Check

• All tools have writesMemory: boolean flag
• capabilitiesVersion ensures tool validity checks use current catalog
• sequentialThinking requires capabilities to be loaded first

Scratchpad Schema

scratchpad = {
  messageId: string,               // Invariant A
  memoryUpdatedEntities: string[], // Invariant C  
  capabilitiesVersion: string,     // Invariant D
  
  activeEntities: string[],
  currentIntent: string | null,
  lastPlan: { nodes, edges, linearPlan } | null,
  compactContext: { facts, constraints, missing, ... } | null,
  
  stepCount: number,
  toolCallCount: number,
  planningCallCount: number,
}

Safety Limits

Research Intensity (Boolean-Based)

Research depth is determined by boolean flags only, not arbitrary numeric scores:

needsDeepResearch = (
  userWantsDeepResearch ||
  memory.isStale ||
  memory.isIncomplete ||
  memory.hasContradictions
)

Workflow

User Query
    │
    ├─ initScratchpad(intent) → messageId generated
    │
    ├─ queryMemory → boolean quality flags
    │
    ├─ If multi-entity → decomposeQuery
    │
    ├─ If complex → sequentialThinking (requires capabilities)
    │
    ├─ Execute tool
    │
    ├─ compactContext(messageId) → stamp output
    │
    ├─ updateScratchpad(messageId) → guard mismatch
    │
    ├─ If tool.writesMemory → markMemoryUpdated
    │
    └─ Generate response

Agentic Context Engineering

Based on Nate B. Jones's deep dive synthesizing findings from Google ADK, Anthropic ACE, and Manus architectures.

The Core Thesis

"True Agentic Memory is not a prompt or a database; it is a system."

Simply increasing context windows (e.g., 1 million tokens) does not solve the memory problem for AI agents. In fact, it often hurts performance by introducing noise and "attention scarcity." The solution is a structured memory architecture with explicit tiers, retrieval mechanisms, and isolation guarantees.

Invariant Enforcement

The 4 Code-Enforced Invariants (documented above) map directly to Agentic Context Engineering principles:

Skills System

The platform implements a Skills System based on Anthropic's Skills specification (v1.0, October 2025). Skills are pre-defined multi-step workflows that combine tools for common tasks.

What Are Skills?

Skills sit between atomic tools and full agent delegation:

Progressive Disclosure Pattern

Skills use a progressive disclosure pattern for token efficiency:

1. Discovery: searchAvailableSkills - Returns only skill names + brief descriptions
2. Browsing: listSkillCategories - Browse skills by category
3. Loading: describeSkill - Load full markdown instructions on-demand

This achieves 90%+ token savings compared to loading all instructions upfront.

Core Skills

Skill Format (SKILL.md)

Skills follow the Anthropic specification with YAML frontmatter:

---
name: company-research
description: Research a company comprehensively
license: Apache-2.0
allowed-tools:
  - delegateToAgent
  - searchAvailableTools
  - invokeTool
---

## Company Research Workflow

### Step 1: Identify the Company
...

Database Schema

Frontend Integration

The Skills Panel in Fast Agent Panel provides:

• Search: Hybrid search (BM25 + semantic) for skill discovery
• Browse: Category-based filtering
• Quick Use: One-click skill insertion into chat

Seeding Skills

# Seed core skills to database
npx convex run tools/meta/seedSkillRegistry:seedSkillRegistry

Knowledge Graph System

The platform includes a claim-based Knowledge Graph for entity analysis, clustering, and outlier detection:

Core Concepts

• Claim Graphs: Represent knowledge as SPO (Subject-Predicate-Object) triples with provenance
• Graph Fingerprints: Semantic (embedding) and structural (WL hash) fingerprints for similarity
• Clustering: HDBSCAN for natural grouping with automatic outlier detection
• Novelty Detection: One-Class SVM "soft hull" for identifying unusual entities

Tables

Tools

Boolean Outputs

All clustering results use boolean flags (no magic scores):

• isOddOneOut - HDBSCAN noise label
• isInClusterSupport - One-Class SVM inlier/outlier
• clusterId - Assigned cluster (null = outlier)

Artifact Streaming & Per-Section Linking

Real-time artifact extraction and per-section linking for dossiers and research reports.

Overview

When the Coordinator runs research tools, artifacts (URLs, sources) are automatically:

1. Extracted from tool results
2. Persisted to the database with deduplication
3. Linked to the current dossier section
4. Displayed in per-section MediaRails and a global SourcesLibrary

Tables

Per-Section Linking

The Coordinator calls setActiveSection before each section's research:

setActiveSection({ sectionKey: "market_landscape", runId })
linkupSearch("Tesla market analysis")  // → linked to "market_landscape"

Section Keys: executive_summary, company_overview, market_landscape, funding_signals, product_analysis, competitive_analysis, founder_background, investment_thesis, risk_flags, open_questions, sources_and_media

Status: ✅ Complete - Editor Fully Functional

Overview

Fixed critical BlockNote editor schema error and implemented comprehensive concurrent edit system for Deep Agent document modifications with sequential processing, visual indicators, and version validation.

Issues Fixed

1. BlockNote "Every schema needs a 'text' type" Error

• Root Cause: Client code expected Convex API re-exports at convex/ root level, but implementations were in domain-organized directories
• Solution: Created re-export files for backward compatibility:
  • convex/prosemirror.ts - Re-exports prosemirror sync functions
  • convex/tags.ts - Re-exports tag functions
  • convex/presence.ts - Re-exports presence functions
  • convex/agentsPrefs.ts - Agent preferences API
• Result: Editor now initializes correctly without schema errors

2. BlockNote Import Path Issue

• Problem: filterSuggestionItems import from @blocknote/core was failing
• Solution: Updated import to @blocknote/core/extensions (API change in newer versions)
• File: src/features/editor/components/UnifiedEditor.tsx line 20

Deep Agent Concurrent Edit System

Architecture

   • Maintains queue of pending edits from agent
   • Processes edits sequentially to prevent conflicts
   • Tracks edit status (pending, applied, failed)
   • Handles optimistic updates and rollback

2. Visual Edit Indicators (src/features/editor/components/UnifiedEditor/PendingEditHighlights.tsx)

   • Highlights anchor regions being edited by agent
   • Shows edit progress with color-coded states
   • Smooth animations for edit application
   • Prevents user interaction during critical edits

• Pattern-based funding event detection from feed items
• Cross-source verification with confidence scoring
• Entity promotion pipeline for banker-grade dossiers

3. Multi-Persona Morning Brief (convex/workflows/dailyMorningBrief.ts)

• runAgentPoweredDigest action with persona parameter
• Breaking alert detection with urgency classification
• Multi-channel payload storage (ntfy, Slack, email-ready)
• Export function for offline inspection (exportDailyBriefNtfyPayloads)

4. Quality Refinements (3-Iteration Loop)

• Iteration 1: Persona normalization + entity spotlight parsing fixes
• Iteration 2: Diverse persona prompts + fundingStage cleanup
• Iteration 3: Final validation across CTO_TECH_LEAD and JPM_STARTUP_BANKER personas

Nodebench AI Intelligence Engine: Product Requirement Document (PRD)

Version: 2.0 | Status: Approved for Engineering | Scope: Backend Agent Architecture

1. Executive Summary

This document outlines the architectural requirements for the Nodebench AI Intelligence Engine, a high-end, self-adaptive research platform. The system transitions from fragile, heuristic-based logic to a durable, agent-driven architecture powered by Convex.

Core Philosophy:

1. Self-Adaptive: The system determines its own execution path (Fast Stream vs. Deep Research) via LLM reasoning, not client-side if/else blocks.
2. Durable & Self-Healing: All complex operations are wrapped in transactional workflows that survive server restarts and automatically retry transient failures.
3. Multi-Modal Realtime: The same intelligence backend powers both high-frequency text streaming and low-latency voice interfaces.

2. System Architecture: The "Router & Worker" Model

2.1 The Adaptive Router (The Entry Point)

Requirement: All incoming user requests must pass through a centralized "Coordinator Agent" that classifies intent before execution. Mechanism:

• Use generateObject to classify requests into SIMPLE (Direct Response) or COMPLEX (Research Plan).
• Implementation:

  // The Router decides the path
  const plan = await coordinator.generateObject(ctx, {
    prompt: "Classify and plan: Simple response or Multi-step research?",
    schema: z.object({ mode: z.enum(["simple", "complex"]), tasks: z.array(...) })
  });
  

• Optimization: This removes client-side heuristics. The agent "heals" bad requests by re-planning rather than failing.
• Documentation: Generating Structured Objects

2.2 Path A: The Fast Stream (Low Latency)

Requirement: For SIMPLE queries, the system must provide immediate feedback (<200ms TTFB). Mechanism:

• Bypass the heavy workflow engine.
• Invoke a lightweight Agent (e.g., gpt-4o-mini) with stepCountIs(1) constraints.
• Streaming: Use streamText with saveStreamDeltas: true to write incremental updates directly to the Convex Database.
• Documentation: Agent Streaming | Retrieving Streamed Deltas

2.3 Path B: The Deep Thinking Workflow (High Fidelity)

Requirement: For COMPLEX queries, the system must orchestrate multiple specialized sub-agents without timing out or losing state. Mechanism:

• Orchestration: Use the Convex Workflow component. This ensures that if a 5-minute research task fails at minute 4, it retries from the last checkpoint, not the beginning.
• Parallelism: Execute sub-tasks (e.g., "Search SEC Filings" and "Check TechCrunch") in parallel using step.runAction.
• Infrastructure: Wrap logic in WorkflowManager to utilize the Workpool for concurrency limits (preventing rate-limit bans).
• Documentation: Workflow Component | Durable Workflows & Guarantees

3. Core Agent Capabilities

3.1 Tooling & External Access (Width)

Requirement: Agents must possess "Width" (access to the outside world) to ground their research. Tools Implementation:

• Web Search: Integration with Linkup/Tavily APIs via createTool.
• RAG: Hybrid search over internal documents using the Convex Agent hybrid search capabilities.
• Documentation: Agent Tools | RAG with Agent Component

3.2 Context Management (Memory)

Requirement: The agent must adapt its context window dynamically based on the task phase (e.g., "don't read the whole thread when summarizing a single document"). Mechanism:

• Use contextHandler to programmatically filter, summarize, or inject specific memories before the prompt hits the LLM.
• Documentation: Full Context Control

3.3 Self-Correction (Quality Control)

Requirement: The system must detect hallucinations or poor outputs without human intervention. Mechanism:

• Critic Loop: A Workflow step where a secondary agent (The "Grader") reviews the output of the primary agent.
• Loop: If the score is < 80%, the workflow loops back to the generation step with feedback.
• Documentation: Building Reliable Workflows

4. Realtime & Voice Interfaces

4.1 Unified Voice Backend

Requirement: The platform must support a "Phone Mode" or "Voice Chat" without duplicating logic. Mechanism:

• Transport: Use Convex httpAction to receive events from voice clients (RTVI / Daily Bots).
• Logic: The HTTP action triggers the exact same Agent/Workflow logic used by the text chat.
• Response: Results are piped back via HTTP or stored in the DB for the frontend to reactively update.
• Documentation: Shop Talk: Voice Agents | Realtime Capabilities

4.2 Hybrid Streaming

Requirement: Voice and Text must remain in sync. Mechanism:

• Use Persistent Text Streaming to allow the voice provider to read tokens as they are generated, while simultaneously updating the web UI.
• Documentation: Persistent Text Streaming Component

5. Reliability & Infrastructure Optimization

5.1 Production Guardrails

Requirement: Prevent "Runaway Agents" from draining credits or crashing the DB. Mechanism:

• Rate Limiting: Use the Rate Limiter Component to cap tokens-per-minute per user.
• Usage Tracking: Implement usageHandler to log token consumption for billing.
• Documentation: Rate Limiter Component | Usage Tracking

5.2 Performance Tuning

Requirement: High-throughput mutations (e.g., streaming chunks from 100 concurrent agents) must not cause conflicts. Mechanism:

• Sharded Counters: Use Sharded Counter Component for tracking stats.
• Hot/Cold Tables: Separate "Streaming Deltas" (high write) from "Thread Metadata" (low write) to minimize transaction conflicts.
• Documentation: Sharded Counter | High Throughput Patterns
