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

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

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)

// 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

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

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

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

-- 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

# 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

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

;; 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

Conversation Branch Awareness (Higher-Order Wiring)

Track conversation threads as wiring diagrams - morphisms between topic states.

Branch Detection Schema

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
           └────────┬────────┘

Branch Detection Heuristics

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:

-- 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

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.
