Unified Conversation Logger v1.2.5

Version: 1.2.5 (Critical Fixes Edition)
Author: stackBlock
License: MIT
OpenClaw: >= 2026.2.12

A dual-output conversation logger for OpenClaw that captures everything - user messages, assistant responses, sub-agent conversations, tool calls, and system events - to both JSONL (backup) and Memvid (semantic search) formats.

Memvid: A single-file memory layer for AI agents with instant retrieval and long-term memory. Persistent, versioned, and portable memory, without databases.

"Replace complex RAG pipelines with a single portable file you own, and give your agent instant retrieval and long-term memory."

⚠️ Security & Privacy Notice

Before installing, please understand:

This skill captures everything - by design. It logs all user messages, assistant responses, sub-agent conversations, tool outputs, and system events to local files. This enables powerful long-term memory but requires trust.

What you should know:

Broad capture scope: This is intentional - the skill's purpose is complete conversation logging
Sensitive data risk: Tool outputs (commands, API responses, file contents) are logged. Review what tools expose.
Continuous logging: Once installed, it runs automatically on every assistant response until removed
Optional cloud mode: API mode with MEMVID_API_KEY sends data to memvid.com (third-party service). Free/local modes keep data on your machine only.
Your responsibility: Secure the JSONL/.mv2 files, rotate logs regularly, and audit what gets captured.

Mitigations available:

Use Free/Sharding mode to keep data local (no API key needed)
Change default paths to encrypted locations
Review tools/log.py before installing to understand exactly what gets logged
File permissions: restrict access to log files (chmod 600)

This skill is for users who want complete conversation memory and accept the privacy trade-offs.

✨ What Makes This Different

📝 Dual Storage - Every message saved to JSONL + Memvid simultaneously
🔍 Semantic Search - Ask "What did the researcher agent find about Tesla?" not just keyword search
🤖 Full Context - Captures user input, assistant output, agent chatter, tool results
💾 Three Modes - API (unlimited), Free (50MB), or Sharding (multi-file)
🚀 Always On - Hooks into OpenClaw automatically

Quick Install (Choose Your Mode)

Option 1: API Mode (Recommended) - Near Limitless Memory

Best for: Heavy users, unified search across everything
Cost: $59-299/month via memvid.com

bash

# 1. Get API key from memvid.com ($59/month for 1GB, $299 for 25GB)
export MEMVID_API_KEY="your_api_key_here"
export MEMVID_MODE="single"

# 2. Install
npm install -g memvid
git clone https://github.com/stackBlock/openclaw-memvid-logger.git
cp -r openclaw-memvid-logger ~/.openclaw/workspace/skills/

# 3. Create unified memory file
memvid create ~/memory.mv2

# 4. Start OpenClaw - everything logs to one searchable file

Search everything at once:

bash

memvid ask memory.mv2 "What did we discuss about BadjAI?"
memvid ask memory.mv2 "What did the researcher agent find about Tesla?"
memvid ask memory.mv2 "Show me all the Python scripts I asked for"

Option 2: Free Mode (50MB Limit) - Complete Memory in One Place

Best for: Testing, light usage, single searchable file
Cost: FREE

bash

# 1. Install (no API key needed)
npm install -g memvid
git clone https://github.com/stackBlock/openclaw-memvid-logger.git
cp -r openclaw-memvid-logger ~/.openclaw/workspace/skills/
export MEMVID_MODE="single"

# 2. Create memory file
memvid create ~/memory.mv2

# 3. Start OpenClaw

⚠️ Limit: 50MB (~5,000 conversation turns). When you hit it:

Archive and start fresh, OR
Upgrade to API mode ($59-299/month), OR
Switch to Sharding mode

Option 3: Sharding Mode - More Than 50MB, Free Forever

Best for: Long-term use, staying under free tier
Cost: FREE
Trade-off: Multi-file search

bash

# 1. Install (no API key needed)
npm install -g memvid
git clone https://github.com/stackBlock/openclaw-memvid-logger.git
cp -r openclaw-memvid-logger ~/.openclaw/workspace/skills/
export MEMVID_MODE="monthly"  # This is the default

# 2. Start OpenClaw - auto-creates monthly files

How it works:

memory_2026-02.mv2 (February)
memory_2026-03.mv2 (March - auto-created)
Each file stays under 50MB

⚠️ Sharding Search Differences:

Single-file search (API/Free modes):

bash

# One search gets everything
memvid ask memory.mv2 "What car did I decide to buy?"
# Returns: Results from ALL conversations across ALL time

Sharding search (requires multiple queries):

bash

# Must search each month separately
memvid ask memory_2026-02.mv2 "car decision"  # Recent
memvid ask memory_2026-01.mv2 "car decision"  # January

# Or use a wrapper script to search all files
for file in memory_*.mv2; do
    echo "=== $file ==="
    memvid ask "$file" "car decision" 2>/dev/null | head -5
done

# You must know which month the conversation happened
# No cross-month context - "compare this month to last month" won't work

Why sharding is harder:

Can't ask "what did we discuss in the past 3 months?" in one query
No unified timeline across months
Must remember which month you talked about what
No cross-file semantic comparison

What Gets Logged

Role Tags (Automatic)

Role	Tag	Example Search
User	`[user]`	"What did I say about Mercedes?"
Assistant	`[assistant]`	"What did you recommend?"
Sub-agents	`[agent:researcher]`, `[agent:coder]`	"What did the researcher find?"
System	`[system]`	"When did the cron job run?"
Tools	`[tool:exec]`, `[tool:browser]`	"What commands were run?"

Everything Captured

✅ User messages (what you type)
✅ Assistant responses (what I say back)
✅ Sub-agent conversations (researcher, coder, vision, math, etc.)
✅ Tool executions (bash commands, browser actions, file edits)
✅ Background processes (cron jobs, heartbeats, scheduled tasks)
✅ System events (config changes, restarts, errors)

Usage Examples

Natural Language Search

bash

# What did you say about...?
memvid ask memory_2026-02.mv2 "What was your recommendation about the Mercedes vs Tesla?"

# What did I ask for...?
memvid ask memory_2026-02.mv2 "What Python scripts did I request last week?"

# What did agents do...?
memvid ask memory_2026-02.mv2 "What did the researcher agent find about options trading?"

# System events...?
memvid ask memory_2026-02.mv2 "When did the PowerSchool grades cron job run?"

Keyword Search

bash

# Find specific terms
memvid find memory_2026-02.mv2 --query "Mercedes"

# With filters
memvid find memory_2026-02.mv2 --query "script" --tag agent:coder

Temporal Queries

bash

memvid when memory_2026-02.mv2 "yesterday"
memvid when memory_2026-02.mv2 "last Tuesday"
memvid when memory_2026-02.mv2 "3 days ago"

⚡ Search Performance Guide

Memvid has three search modes. This skill uses --mode neural by default for maximum accuracy:

Default: Neural Search (Recommended)

bash

# Always use neural for semantic understanding and context
memvid ask memory.mv2 "What supplements did Dr. Sinclair recommend?" --mode neural
memvid ask memory.mv2 "What did we discuss about BadjAI?" --mode neural
memvid ask memory.mv2 "Show me the Python scripts I requested" --mode neural

Speed: ~200ms | Best for: Semantic understanding, context, synonyms, conceptual relationships

Alternative Modes (Use When Explicitly Requested)

Mode 1: Lexical Search (Fastest)

bash

# Use only for exact keyword matching when speed is critical
memvid find memory.mv2 --mode lex --query "metformin"

Speed: ~8ms | Use when: Exact word matching needed, latency is critical

Mode 2: Hybrid Search (Balanced)

bash

# Combines lexical + neural
memvid find memory.mv2 --mode hybrid --query "diabetes medications"

Speed: ~300-500ms | Use when: You want both exact matches and semantic similarity

Why Neural as Default?

Mode	Speed	Accuracy	Use Case
`neural`	~200ms	Highest	Default - semantic understanding
`lex`	~8ms	Keyword only	Speed-critical exact matches
`hybrid`	~300-500ms	High	Balanced approach

The ~200ms trade-off is worth it: Neural mode understands context, handles paraphrases, and finds conceptually related information that lexical search misses entirely.

JSONL Backup

bash

# Quick grep
grep "Mercedes" conversation_log.jsonl

# Complex queries with jq
jq 'select(.role_tag == "user" and .content | contains("Python"))' conversation_log.jsonl

# Time range
jq 'select(.timestamp >= "2026-02-01" and .timestamp < "2026-03-01")' conversation_log.jsonl

Configuration

Environment Variables

Variable	Default	Mode	Description
`MEMVID_API_KEY`	(none)	API	Your memvid.com API key
`MEMVID_MODE`	`monthly`	All	`single` or `monthly`
`JSONL_LOG_PATH`	`~/workspace/conversation_log.jsonl`	All	Backup log file
`MEMVID_PATH`	`~/workspace/memory.mv2`	All	Base path for memory files
`MEMVID_BIN`	`~/.npm-global/bin/memvid`	All	Path to memvid CLI

OpenClaw Hooks (Advanced)

Add to openclaw.json:

json

{
  "hooks": {
    "internal": {
      "enabled": true,
      "entries": {
        "conversation-logger": {
          "enabled": true,
          "command": "python3 ~/.openclaw/workspace/skills/unified-logger/tools/log.py"
        }
      }
    }
  }
}

Memory File Formats

Mode 1: Single File (API or Free Mode)

text

memory.mv2
├── [user] messages
├── [assistant] responses  
├── [agent:researcher] findings
├── [agent:coder] code
├── [tool:exec] commands
└── [system] events

Mode 2: Sharding (Monthly Rotation)

text

memory_2026-01.mv2  (January conversations)
memory_2026-02.mv2  (February conversations) ← Current
memory_2026-03.mv2  (March, auto-created on March 1)

Troubleshooting

"Free tier limit exceeded" (Free Mode)

bash

# Option 1: Archive and start fresh
mv memory.mv2 memory_archive.mv2
memvid create memory.mv2

# Option 2: Switch to monthly sharding
export MEMVID_MODE="monthly"

# Option 3: Get API key
export MEMVID_API_KEY="your_key"  # $59-299/month at memvid.com

"Cannot find memory file" (Sharding Mode)

Current month's file auto-creates. If missing:

bash

memvid create memory_$(date +%Y-%m).mv2

Missing agent conversations

Agents log to their own sessions. Ensure skill is installed in main agent workspace and sub-agents inherit it.

Search returns wrong speaker

Memvid uses semantic search. Be specific:

❌ "Mercedes" → Returns all mentions
✅ "What did I say about Mercedes" → Targets [user] frames
✅ "Your recommendation about Mercedes" → Targets [assistant] frames

Comparing the Three Modes

Feature	API Mode	Free Mode	Sharding Mode
Cost	$59-299/mo	FREE	FREE
Capacity	1-25GB+	50MB	Unlimited (files)
Files	1	1	Multiple (monthly)
Unified Search	✅ Yes	✅ Yes	❌ Per-file only
Cross-Context Search	✅ Full history	✅ Full history	❌ Month isolated
Best For	Power users	Testing	Long-term free use
Complexity	Simple	Simple	Must track files

💸 The Pricing Gap (AKA Why Sharding Exists)

The situation: Memvid's pricing goes from $0 (50MB) straight to $59/month (25GB).
The problem: That's like buying a Ferrari when you just need a Honda Civic for your commute.

What we're doing about it:
I reached out. While they consider it, Sharding Mode exists so you don't have to pay Ferrari prices for Honda Civic usage.

You can help:
If you also think $0 → $59 is a bit much, reach out to Memvid at memvid.com and tell them stackBlock sent you. The more voices, the faster we get that $10-20 middle tier for the rest of us.

Until then: Sharding Mode. Because startups shouldn't have to choose between ramen and memory. 🍜

Future Enhancements

Auto-archive old months to cold storage
Web UI for browsing conversations
Cross-file search wrapper script
Export to other formats (Markdown, PDF)
Conversation threading visualization
