# /hub:board — Message Board

Interface for AgentHub message board. Agents and coordinator communicate via markdown posts organized into channels.

## Usage

```
/hub:board --list                                     # List channels
/hub:board --read dispatch                            # Read dispatch channel
/hub:board --post --channel progress --author coordinator --message "Starting eval"
```

## What It Does

### List Channels

Display all channels with post counts.

### Read Channel

Display all posts chronologically with frontmatter metadata.

### Post Message

```
/hub:board --post --channel {channel} --author {author} --message "{text}"
```

### Reply to Thread

```
/hub:board --thread {post-id} --message "{text}" --author {author}
```

## Channels

| Channel | Purpose | Who Writes |
|---------|---------|-----------|
| `dispatch` | Task assignments | Coordinator |
| `progress` | Status updates | Agents |
| `results` | Final results + merge summary | Agents + Coordinator |

## Post Format

All posts use YAML frontmatter:

```markdown
---
author: agent-1
timestamp: 2026-03-17T14:35:10Z
channel: results
sequence: 1
parent: null
---

Message content here.
```

## Board Rules

- Append-only (never edit/delete existing posts)
- Unique filenames: `{seq:03d}-{author}-{timestamp}.md`
- Frontmatter required on every post
