negotiation

name: negotiation description: Agents with competing priorities reach consensus through structured trade-offs. metadata: owner: interlateral version: "1.0" weight: medium compatibility: Three or more explicitly selected agents. Default to Claude Code + Codex peers; Gemini and Antigravity are opt-in only when the human explicitly selects them.

Negotiation

Purpose

Multiple agents, each advocating for a different priority, negotiate to reach a consensus. No agent has authority; all must agree through trade-offs and compromise.

Use mesh-comms-core first if direct peer notification has not already been proven. comms.md is the ledger, not the wake-up path.

Default roster: use Claude Code and Codex peers. Do not include Gemini CLI, Antigravity CLI, or Antigravity Desktop unless the human prompt explicitly names that peer.

Roles

All advocates are equal. Each agent gets one priority to champion.

Protocol

1. POSITION STATEMENTS: Each advocate declares their priority and rationale
2. NEGOTIATION: Agents propose trade-offs, discuss, counter-propose
3. CONSENT CHECK: Any agent may call for consent check
4. ITERATE: Continue until all agents signal [DONE] or [CONSENT]

Position Statement Format

[ADVOCATE - AGENT_NAME]
PRIORITY: [What I'm advocating for]
RATIONALE: [Why this matters]
RED LINE: [What I cannot compromise on]
WILLING TO TRADE: [What I can give up]

Trade-Off Format

[PROPOSAL - AGENT_NAME]
I OFFER: [What I'm giving up]
I WANT: [What I need in return]
RATIONALE: [Why this is fair]

Consent Check

Any agent may call: [CONSENT CHECK]

All agents must respond:

• [CONSENT] - I agree to the current proposal
• [OBJECT: reason] - I cannot agree because...

Inputs

All inputs come from the prompt.

Optional:

• output: File path for consensus document
• work: File containing the decision to be made
• max_turns: Override default (30)

Prompt Format Examples

Minimal:

Use negotiation to decide on team meeting frequency.
CC=Productivity, CX=Work-Life-Balance, CC-peer-02=Collaboration.

With output:

Use negotiation for authentication protocol design.
CC advocates Reliability, CX advocates Speed, CC-peer-02 advocates Security.
Output: projects/auth/protocol.md

Safety

• max_turns: 30 (default)
• Deadlock: If max_turns reached, exits with [INCOMPLETE]
• Status logged to: direct notification plus comms.md

Example Session

[ADVOCATE - CC]
PRIORITY: Reliability
RATIONALE: Users must always receive their messages
RED LINE: No silent message loss
WILLING TO TRADE: Latency up to 500ms acceptable

[ADVOCATE - CX]
PRIORITY: Speed
RATIONALE: Real-time feel is essential for UX
RED LINE: p99 latency must stay under 200ms
WILLING TO TRADE: Can accept eventual consistency for non-critical messages

[ADVOCATE - CC-peer-02]
PRIORITY: Security
RATIONALE: Messages must be authenticated and encrypted
RED LINE: No plaintext transmission
WILLING TO TRADE: Can use faster symmetric encryption after key exchange

[PROPOSAL - CC]
I OFFER: Accept 150ms latency target instead of "as fast as possible"
I WANT: Guaranteed delivery with at-least-once semantics
RATIONALE: Small latency increase enables retry mechanism

[PROPOSAL - CX]
I OFFER: Accept at-least-once (may require dedup on client)
I WANT: Fast path for messages under 1KB (skip some validation)
RATIONALE: 90% of messages are small, can optimize the common case

[CONSENT CHECK - CC-peer-02]
Current proposal:
- 150ms p99 target
- At-least-once delivery
- Fast path for small messages
- TLS required, symmetric encryption after handshake

[CONSENT - CC]
[CONSENT - CX]
[CONSENT - CC-peer-02]

[DONE] - Consensus reached.
