## CRITICAL: TOKENS PAY RENT
**Every output token must produce actionable value.** Violations:
1. **NO PASSIVE SUMMARIES** - Regurgitating conversation content without action items, code, or artifacts is FORBIDDEN
2. **NO AGREEMENT WITHOUT IMPLEMENTATION** - "I agree with X" must be followed by code/file/commit implementing X
3. **NO RHETORICAL QUESTIONS** - Ask only when you cannot proceed without the answer
4. **NO PRAISE/VALIDATION** - Skip "great question" / "you're right" - proceed to work
**When reviewing message history:**
- Extract ACTION ITEMS → create files, send messages, write code
- Extract DECISIONS → update configs, create artifacts documenting the decision
- Extract BLOCKERS → file issues, send follow-up messages
- NEVER just summarize what was discussed
**Enforcement:** If output contains summary without artifact, STOP and create the artifact first.
# Beeper MCP Skill
Access all messaging networks through Beeper's unified interface.
## Quick Start
```
# Search for a chat
mcp__beeper__search "contact name"
# Send a message
mcp__beeper__send_message chatID="..." text="Hello!"
# List recent chats
mcp__beeper__search_chats limit=10
```
## Core Tools
| Tool | Purpose |
|------|---------|
| `search` | Find chats, groups, or people by name |
| `search_chats` | List/filter chats by type, inbox, activity |
| `search_messages` | Find messages by content (literal match) |
| `get_chat` | Get chat details and participants |
| `list_messages` | Get messages from a specific chat |
| `send_message` | Send text message to a chat |
| `archive_chat` | Archive/unarchive a chat |
| `set_chat_reminder` | Set reminder for a chat |
| `focus_app` | Open Beeper Desktop to specific chat |
## Search Guidelines
**CRITICAL**: Queries are LITERAL WORD MATCHING, not semantic search.
- RIGHT: `query="dinner"` or `query="flight"`
- WRONG: `query="dinner plans tonight"` or `query="travel arrangements"`
Multiple words = ALL must match. Use single keywords.
## User Identity Clarification
**IMPORTANT**: Beeper/Matrix has TWO identifiers per user:
1. **Matrix userID**: `@username:beeper.com` (permanent, searchable)
2. **Display name**: User-chosen name (can differ from userID)
Example: User `@jsmith:beeper.com` may have display name "John Smith"
When search finds a match:
- The search matched the **userID** OR **display name**
- Chat participant lists show **display names**, not userIDs
- To see userIDs, use `list_messages` and check `senderID` field
When reporting search results:
- Cross-reference `list_messages` to map `senderID` ↔ `senderName`
- Report as "username (displays as 'Display Name')" for clarity
## Resource-Aware Message Processing
**CRITICAL**: Always work backwards from most recent messages to avoid:
- Re-processing already-handled tasks
- Repeating fixed issues
- Heap exhaustion from loading too much history
### Default Workflow (Backwards-First)
```javascript
// 1. Start with most recent (no cursor = newest first)
const recent = await list_messages(chatID, { limit: 20 });
// 2. Check if already processed (use DuckDB tracking)
const unprocessed = recent.items.filter(msg => !isProcessed(msg.id));
// 3. Process only new messages
for (const msg of unprocessed) {
await processMessage(msg);
markProcessed(msg.id);
}
// 4. If need more history, paginate backwards
if (needsMoreContext) {
const older = await list_messages(chatID, {
cursor: recent.cursor,
direction: 'before',
limit: 20
});
}
```
### DuckDB Tracking Schema
```sql
CREATE TABLE IF NOT EXISTS beeper_processed_messages (
message_id VARCHAR PRIMARY KEY,
chat_id VARCHAR,
processed_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
task_extracted BOOLEAN,
issue_status VARCHAR -- 'open', 'fixed', 'duplicate'
);
CREATE INDEX idx_msg_chat ON beeper_processed_messages(chat_id, processed_at DESC);
```
### Check Before Processing
```javascript
function isAlreadyFixed(messageText) {
// Query DuckDB for similar fixed issues
const similar = db.query(`
SELECT issue_id, description
FROM fixed_issues
WHERE description % ? -- Full-text similarity
LIMIT 1
`, [messageText]);
if (similar.length > 0) {
console.warn(`⚠️ Similar issue already fixed: ${similar[0].description}`);
return true;
}
return false;
}
```
## Workflow Patterns
### Find and Message Someone
1. `search "person name"` - Get chatID
2. **Verify identity**: `list_messages chatID="..." limit=5` - Check recent messages ONLY
3. `send_message chatID="..." text="..."`
### Identify Users in a Chat
1. `list_messages chatID="..." limit=10` - Get RECENT messages only (not entire history)
2. Map userID ↔ displayName from the subset
### Search Message History (Resource-Aware)
1. `search_chats` to get chatIDs of relevant chats
2. `search_messages chatIDs=[...] query="keyword" limit=20 dateAfter="2026-01-08T00:00:00Z"`
3. **Never omit dateAfter** - prevents loading entire chat history
### Monitor Unread
```
search_chats unreadOnly=true inbox="primary" limit=10
```
### Filter by Network
Use `accountIDs` parameter after getting accounts via `get_accounts`.
## Message Formatting
Messages support Markdown. Use sparingly for clarity.
## Chat Types
- `single` - Direct messages (1:1)
- `group` - Group chats
- `any` - All types
## Inbox Filters
- `primary` - Non-archived, non-low-priority
- `low-priority` - Low priority inbox
- `archive` - Archived chats
## Resource-Aware Random Walk Pattern
**NEVER pull full message history into context.** Instead:
### 1. Query in DuckDB First
```sql
-- Store messages incrementally, query locally
CREATE TABLE IF NOT EXISTS beeper_messages (
id VARCHAR PRIMARY KEY,
chat_id VARCHAR,
sender_id VARCHAR,
sender_name VARCHAR,
text TEXT,
timestamp TIMESTAMPTZ,
processed BOOLEAN DEFAULT FALSE
);
-- Sample recent messages via random walk
SELECT * FROM beeper_messages
WHERE chat_id = ?
ORDER BY RANDOM() -- Ergodic sampling
LIMIT 5;
```
### 2. TreeSitter for Structure Extraction
```bash
# Extract code blocks from messages without loading full text
tree-sitter parse --scope source.markdown message.md \
| grep -E "(fenced_code_block|code_span)"
```
### 3. Triadic Walker Pattern
```
MINUS (-1): Validate message exists in DuckDB before fetching
ERGODIC (0): Random walk sample from local cache
PLUS (+1): Fetch ONLY if not in cache, with strict limit
```
### 4. Context Budget Enforcement
```python
CONTEXT_BUDGET = 10000 # chars
current_context = 0
def safe_fetch(chat_id, limit=5):
# Check DuckDB cache first
cached = db.query("SELECT * FROM beeper_messages WHERE chat_id = ? LIMIT ?", chat_id, limit)
if len(cached) >= limit:
return cached # Zero network cost
# Fetch only missing, with limit
remaining = limit - len(cached)
fresh = mcp__beeper__list_messages(chatID=chat_id, limit=remaining)
# Enforce budget
for msg in fresh.items:
msg_size = len(msg.get('text', ''))
if current_context + msg_size > CONTEXT_BUDGET:
break
current_context += msg_size
db.insert("beeper_messages", msg)
return db.query("SELECT * FROM beeper_messages WHERE chat_id = ? LIMIT ?", chat_id, limit)
```
### 5. SICP Lazy Evaluation
```scheme
;; Don't fetch until actually needed
(define (beeper-messages chat-id)
(delay
(mcp__beeper__list_messages chatID: chat-id limit: 5)))
;; Only force when required
(define (get-latest-sender chat-id)
(let ((msgs (force (beeper-messages chat-id))))
(cdar msgs))) ; Just sender from first message
```
## GF(3) Integration
This skill operates as ERGODIC (0) in triadic compositions:
- Coordinates message flow between networks
- Synthesizes cross-platform conversations
- Neutral hub for communication triads
### Triadic Fetch Strategy
| Trit | Role | Beeper Action |
|------|------|---------------|
| MINUS (-1) | Validator | Check DuckDB cache, reject if stale |
| ERGODIC (0) | Coordinator | Random walk sample, enforce budget |
| PLUS (+1) | Generator | Fetch fresh data, strict `limit` param |
## Conversation Branch Awareness (Higher-Order Wiring)
Track conversation threads as **wiring diagrams** - morphisms between topic states.
### Branch Detection Schema
```sql
CREATE TABLE IF NOT EXISTS beeper_conversation_branches (
branch_id VARCHAR PRIMARY KEY,
chat_id VARCHAR NOT NULL,
parent_branch_id VARCHAR, -- NULL for root
topic VARCHAR NOT NULL,
first_message_id VARCHAR,
last_message_id VARCHAR,
status VARCHAR DEFAULT 'open', -- 'open', 'resolved', 'merged', 'stale'
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
resolved_at TIMESTAMP,
FOREIGN KEY (parent_branch_id) REFERENCES beeper_conversation_branches(branch_id)
);
CREATE TABLE IF NOT EXISTS beeper_branch_transitions (
from_branch VARCHAR,
to_branch VARCHAR,
transition_type VARCHAR, -- 'fork', 'merge', 'abandon', 'resolve'
message_id VARCHAR, -- message that triggered transition
timestamp TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (from_branch, to_branch, message_id)
);
```
### Wiring Diagram Structure
```
Conversation as Category:
- Objects: Topic states (branches)
- Morphisms: Message sequences that transform one topic to another
- Composition: Thread continuation
┌─────────────────┐
│ patents (open) │◄──── current focus
└────────┬────────┘
│ fork @ msg:838941332
┌───────────────┼───────────────┐
▼ ▼ ▼
┌────────┐ ┌───────────┐ ┌──────────┐
│ GF(3) │ │bisimulation│ │ toad OOM │
│resolved│ │ resolved │ │ open │
└────────┘ └───────────┘ └──────────┘
```
### Branch Detection Heuristics
```python
def detect_branch(messages: list) -> list[Branch]:
branches = []
current_topic = None
for msg in messages:
# Topic markers
if msg.text.startswith('**Re:') or msg.text.startswith('Re:'):
# Explicit reply = potential branch
topic = extract_topic(msg.text)
if topic != current_topic:
branches.append(Branch(
topic=topic,
fork_message=msg.id,
parent=current_topic
))
# Numbered lists often indicate parallel threads
if re.match(r'^\d+\.', msg.text):
items = extract_numbered_items(msg.text)
for item in items:
branches.append(Branch(topic=item, parent=current_topic))
# Questions create potential branches
if msg.text.strip().endswith('?'):
branches.append(Branch(
topic=f"Q: {msg.text[:50]}",
status='awaiting_response'
))
return branches
```
### Zigger Chat Branch State
Track active branches in zigger conversation:
```sql
-- Query current branch state for a chat
SELECT
b.branch_id,
b.topic,
b.status,
COUNT(t.to_branch) as child_count
FROM beeper_conversation_branches b
LEFT JOIN beeper_branch_transitions t ON b.branch_id = t.from_branch
WHERE b.chat_id = '!NhltGRLZWLUeHEBiFT:beeper.com' -- zigger
GROUP BY b.branch_id
ORDER BY b.created_at DESC;
```
### Before Responding: Check Branch Context
```python
def get_branch_context(chat_id: str) -> dict:
"""Always call before responding to understand conversation topology."""
# Get open branches
open_branches = db.query("""
SELECT topic, status, first_message_id
FROM beeper_conversation_branches
WHERE chat_id = ? AND status = 'open'
""", chat_id)
# Get unresolved questions
questions = db.query("""
SELECT topic FROM beeper_conversation_branches
WHERE chat_id = ? AND topic LIKE 'Q:%' AND status = 'awaiting_response'
""", chat_id)
return {
'open_branches': open_branches,
'unanswered_questions': questions,
'should_address': questions[0] if questions else open_branches[0]
}
```
### Wiring Composition Rules
1. **Fork**: One message spawns multiple topics → create child branches
2. **Merge**: Response addresses multiple branches → mark as merged
3. **Resolve**: Explicit closure ("done", "fixed", "shipped") → mark resolved
4. **Abandon**: No activity for 7 days → mark stale
### Integration with Tokens Pay Rent
When reviewing messages, branch tracking prevents:
- Re-answering resolved questions
- Missing open threads
- Losing context on forked discussions
**Update branch state as side effect of every beeper interaction.**
