Implicit Coordination

Implicit Coordination Skill

"The trace IS the message." "22 frames with OCR in 10ms, one causality trip."

Overview

Implicit Coordination enables multi-agent systems to coordinate WITHOUT explicit message passing:

                        NO MESSAGES
                     Only environment traces

Core Principle: Stigmergy

Stigmergy (Grassé 1959): Agents coordinate through environment modification.

Traditional:   Agent A --[message]--> Agent B
Stigmergic:    Agent A --[writes]--> Environment <--[reads]-- Agent B

Key insight: The seed chain IS the coordination mechanism:

• Agent +1 (Generator): Writes seed to environment
• Agent 0 (Coordinator): Derives next seed via SplitMix64
• Agent -1 (Validator): Reads and verifies GF(3) conservation

Vehicle Semantics

The carrier encodes meaning (not separate payload):

Performance: One Causality Trip

22 frames OCR → 10ms total → single DuckDB write

vs. Traditional:
22 frames → 22 messages → 22 round trips → 22 acknowledgments

Latency reduction: O(n) → O(1) for n frames.

Implementation

Environment Trace Schema (DuckDB)

CREATE TABLE IF NOT EXISTS stigmergy_traces (
  trace_id VARCHAR PRIMARY KEY,
  seed_hex VARCHAR NOT NULL,
  trit INT CHECK (trit IN (-1, 0, 1)),
  color_hex VARCHAR(7),
  agent_role VARCHAR,  -- 'generator', 'coordinator', 'validator'
  environment_key VARCHAR,  -- What was modified
  environment_value VARCHAR,  -- Serialized state
  causality_ms FLOAT,  -- Time for this trace
  parent_trace_id VARCHAR,
  gf3_running_sum INT DEFAULT 0,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

-- Index for fast derivation lookup
CREATE INDEX IF NOT EXISTS idx_stigmergy_parent ON stigmergy_traces(parent_trace_id);

-- View for GF(3) validation
CREATE VIEW IF NOT EXISTS stigmergy_gf3_check AS
SELECT 
  parent_trace_id,
  SUM(trit) as trit_sum,
  COUNT(*) as trace_count,
  SUM(trit) % 3 = 0 as gf3_conserved

GROUP BY parent_trace_id;

Performance Comparison

Key Insights

1. No coordination protocol needed - agents read/write same environment
2. Seed chain IS causality - no separate ordering mechanism
3. GF(3) emerges from structure - not enforced by messages
4. Vehicle semantics - the carrier (seed) encodes the meaning
