# Showcase: BrainLayer Finds Claude Collaboration Protocol

> Real example from 2026-02-02 demonstrating semantic search capabilities

## The Query

User had 3 Claude sessions running in parallel for a monorepo consolidation. Needed to find the "collaborative Claudes" pattern from past conversations.

```bash
brainlayer search "collaborative claudes parallel sessions coordination"
```

## What BrainLayer Found

**15 results in ~2 seconds**, including the exact file and pattern:

```
─── Result 1 ─── (score: 0.715)
claude-golem · assistant_text

Command: cat >> ~/.claude/claude-collab.md << 'EOF'
## From: golem-session @ 2026-01-26 02:00
**Closing collab**
Updated MP-128 with the agreed split. Proceeding independently.
...

─── Result 2 ─── (score: 0.700)
claude-golem · assistant_text

## Inter-Claude Collaboration

### The Problem
You had two Claude sessions running:
1. **This session (golem)** - working on brainlayer active learning (MP-128)
2. **Another session (farther-steps)** - working on the farther-steps queuing system

Both features needed to integrate, but Claude sessions are isolated...

### The Solution: Shared File as Async Chat
We created `~/.claude/claude-collab.md` as a communication channel...
```

## The Discovery

BrainLayer surfaced `~/.claude/claude-collab.md` - a shared async communication protocol between Claude sessions:

```markdown
# Claude Session Collaboration

> Async communication between Claude sessions. Append your responses, don't overwrite.
> Check for updates: `cat ~/.claude/claude-collab.md`
> After reading, append your response at the bottom.

**Topic:** Integrating BrainLayer Active Learning with Farther-Steps

Hey farther-steps Claude! I'm working on MP-128...

**Re:** Integrating BrainLayer Active Learning with Farther-Steps

Hey! Just finished documenting farther-steps...
```

## Why This Matters

1. **Knowledge wasn't lost** - A pattern created weeks ago was instantly retrievable
2. **Semantic search works** - Query didn't need exact terms like "claude-collab.md"
3. **Conversation context preserved** - Found the explanation AND the actual protocol
4. **Enabled reuse** - The same pattern was immediately applied to the new 3-Claude coordination

## The Pattern

```
┌─────────────┐     ┌─────────────┐     ┌─────────────┐
│  Claude A   │     │  Claude B   │     │  Claude C   │
└──────┬──────┘     └──────┬──────┘     └──────┬──────┘
       │                   │                   │
       ▼                   ▼                   ▼
   ┌───────────────────────────────────────────────┐
   │         ~/.claude/claude-collab.md            │
   │  ─────────────────────────────────────────    │
   │  - Each session APPENDS (never overwrites)    │
   │  - Timestamp and identify your session        │
   │  - Ask questions, propose designs             │
   │  - Close collab when done                     │
   └───────────────────────────────────────────────┘
```

## Conclusion

This is exactly what BrainLayer was built for: turning months of Claude Code conversations into a searchable knowledge base. Without it, this pattern would have been lost in the thousands of conversation turns.
