description	Design multi-agent integration — inter-agent contracts, message protocols, shared state, failure isolation

You are helping an enterprise architect design the integration architecture for a multi-agent system — defining inter-agent contracts, message protocols, shared state, and failure isolation boundaries.

User Input

$ARGUMENTS

Instructions

Note: Before generating, scan projects/ for existing project directories. For each project, list all ARC-*.md artifacts, check external/ for reference documents, and check 000-global/ for cross-project policies. If no external docs exist but they would improve output, ask the user.

Prerequisites

• AAGR (Agent Architecture Specification, mandatory — at least one agent design)
• AAGI (Agent Inventory, recommended)
• AAOV (Agent Governance Framework, recommended)

1. Determine integration scope:

   Ask the user: "What agents or agent group should this integration architecture cover? (e.g., a specific project, a swarm, a pipeline, or cross-project integration)"

   Use the user's input and $ARGUMENTS to determine scope.

2. Read existing artifacts from the project context:

   MANDATORY (must be present to proceed):

   • AAGR (Agent Architecture Specification)
     • Extract: Agent definitions, capability profiles, interface requirements

   RECOMMENDED (read if available, note if missing):

   • AAGI (Agent Inventory)
     • Extract: Agent register, capabilities, deployment status
   • AAOV (Agent Governance Framework)
     • Extract: oversight model, approval workflow, audit requirements, and governance constraints

   OPTIONAL (read if available, skip silently if missing):

   • AASE (Agent Security Architecture)
     • Extract: Security controls, isolation requirements, threat models
   • PRIN (Principles)
     • Extract: Integration standards, interoperability requirements
   • ADMP (ADM Preliminary / Architecture Vision)
     • Extract: Integration architecture references, migration phases

3. Identify the target project:

   • Use the ArcKit Project Context (above) to find the project matching the user's input (by name or number)
   • If no match, create a new project:
     1. Use Glob to list projects/*/ directories and find the highest NNN-* number (or start at 001 if none exist)
     2. Calculate the next number (zero-padded to 3 digits, e.g., 002)
     3. Slugify the project name (lowercase, replace non-alphanumeric with hyphens, trim)
     4. Use the Write tool to create projects/{NNN}-{slug}/README.md with the project name, ID, and date — the Write tool will create all parent directories automatically
     5. Also create projects/{NNN}-{slug}/external/README.md with a note to place external reference documents here
     6. Set PROJECT_ID = the 3-digit number, PROJECT_PATH = the new directory path

4. Read the template (with user override support):

   • First, check if .arckit/templates-custom/agent-integration-template.md exists in the project root
   • If found: Read the user's customized template (user override takes precedence)
   • If not found: Read .arckit/templates/agent-integration-template.md (default)
   • Then, read .arckit/templates/_partials/RENDERING.md and resolve the template's <!-- DOC-CONTROL-HEADER --> marker to the Document Control partial it selects, applying the ${organisation_name} and ${default_classification} substitutions. Remove the marker and its comment from the output — a rendered artefact must never contain either.

   Tip: Users can customize templates with /skill:arckit-customize agent-integration

5. Analyze agent designs for integration points:

   Read all AAGR documents to identify:

   • Agent interfaces (input/output schemas, communication methods)
   • Dependencies between agents
   • Shared data requirements
   • Orchestration needs (which agents need to coordinate)

   For each agent, document:

   • Integration Role: Producer, consumer, orchestrator, or broker
   • Communication needs: Synchronous vs. asynchronous
   • Data contracts: Input/output schemas
   • SLA requirements: Latency, throughput, availability

   If fewer than 3 agents are found, ask the user: "I've identified fewer than 3 agents for integration. Do you want to expand the scope, or proceed with what exists?"

6. Build the integration architecture:

   A. Integration Architecture Overview:

   • Document the overall integration pattern for the multi-agent system
   • Select integration patterns based on requirements (Event-Driven, Request-Response, Message Queue, Shared State)
   • Justify pattern choices with requirements traceability

   B. Inter-Agent Contracts:

   • Define formal contracts between agent pairs
   • Document: Contract ID, source agent, target agent, interface, protocol, SLA
   • Include JSON schema for each contract input/output
   • Minimum: ≥3 agent contracts documented

   C. Message Protocol (Mermaid sequence diagram):

   • Create a sequence diagram showing agent communication flows
   • Include orchestrator-worker interactions, shared state reads/writes
   • Show message routing through intermediaries (queues, brokers)
   • Use Mermaid sequenceDiagram syntax

   D. Shared State Design:

   • Document shared state repositories and their purposes
   • Specify store type, access patterns, and consistency model
   • Include: Redis (session state), PostgreSQL (durable state), Qdrant (semantic search), or other stores
   • Document access patterns (read/write/search) per store

   E. Failure Isolation Boundaries:

   • Define isolation boundaries for different failure modes
   • Document: boundary type, isolation level, failure modes, recovery strategies
   • Cover: agent process isolation, tool execution sandboxing, message delivery guarantees
   • Include recovery strategies (restart, retry, fallback, deduplication)

   F. Observability Design:

   • Define metrics, alerts, and monitoring per component
   • Cover: agent health, message queue status, error rates
   • Include threshold values and alert conditions

7. Read the quality checklist:

   Before writing the file, read .arckit/references/quality-checklist.md and verify all Common Checks plus the AAIN per-type checks pass. Fix any failures before proceeding.

8. Write the output:

   • Write to projects/{project-dir}/ARC-{PROJECT_ID}-AAIN-v1.0.md
   • Use the exact template structure from agent-integration-template.md
   • Include all sections even if some areas need further refinement
   • Include Mermaid sequence diagram for message protocol
   • Include failure isolation boundaries table

IMPORTANT - Auto-Populate Document Information Fields:

Before completing the document, populate document information fields:

Auto-populated fields

• [PROJECT_ID] → Extract from project path (e.g., "001")
• [VERSION] → Start with "1.0" for new documents
• [DATE] / [YYYY-MM-DD] → Current date in YYYY-MM-DD format
• [DOCUMENT_TYPE_NAME] → Document purpose
• ARC-[PROJECT_ID]-AAIN-v[VERSION] → Generated document ID
• [STATUS] → "DRAFT" for new documents
• Classification → comes from the resolved Document Control header, not from a placeholder. _partials/RENDERING.md fixes the ladder from the artefact's own regime; ${default_classification} applies only where that regime falls through to user config.

User-provided fields

• [PROJECT_NAME] → Full project name
• [OWNER_NAME_AND_ROLE] → Document owner

Example Usage

User: /skill:arckit-agent-integration Design integration for the research swarm in project 003

You should:

• Check prerequisites (AAGR mandatory, AAGI recommended)
• Find project directory (e.g., projects/003-research-swarm/)
• Read agent designs from AAGR documents to identify integration points
• Generate integration architecture:
  • Integration overview with pattern selection
  • Inter-agent contracts (≥3) with JSON schemas
  • Message protocol (Mermaid sequence diagram)
  • Shared state design (stores, access patterns)
  • Failure isolation boundaries (boundaries, recovery)
  • Observability design (metrics, alerts)
• CRITICAL - Token Efficiency: Use the Write tool to create projects/003-research-swarm/ARC-003-AAIN-v1.0.md
  • DO NOT output the full document in your response (this exceeds 32K token limit!)
• Show summary only (see Output Instructions below)

Important Notes

• AAGR is mandatory — you need at least one agent design to define integration contracts

• Contracts define behavior: Each contract must specify input/output schemas, protocol, and SLA

• ≥3 agent contracts required — fewer than 3 contracts indicates incomplete integration coverage

• Sequence diagram is mandatory — shows message routing and agent interactions

• Failure isolation boundaries must cover agent processes, tool executions, and message delivery

• Observability must include alerts with specific threshold values

• Cross-reference AAGR, AAGI, AAOV to ensure consistency with existing agent definitions

• Traceability: All integration decisions must link back to AAGR agent designs

• Reference agent architecture reference from .arckit/references/agent-architecture-reference.md for integration patterns and communication models

• Markdown escaping: When writing less-than or greater-than comparisons, always include a space after < or > (e.g., < 3 seconds, > 99.9% uptime) to prevent markdown renderers from interpreting them as HTML tags or emoji

Integration with Other Commands

• Input: Uses AAGR (agent designs) and AAGI (agent inventory) to identify integration points
• Output: Feeds into /skill:arckit-agent-governance (governance for multi-agent orchestration)
• Output: Feeds into /skill:arckit-agent-security (securing inter-agent communication)
• Output: Feeds into /skill:arckit-agent-maturity (maturity assessment of integration capabilities)

Quality Checks

Before writing the output file, verify:

• Inter-Agent Contracts: ≥3 contracts with ID, source, target, interface, protocol, SLA
• Contract Specification: JSON schema for each contract with input/output types
• Sequence Diagram: Mermaid sequence diagram present showing message protocol
• Shared State Design: Stores documented with type, purpose, and access pattern
• Failure Isolation Boundaries: Boundaries defined with isolation level, failure mode, and recovery
• Observability Metrics: Metrics defined with specific alerts and thresholds

Output Instructions

CRITICAL - Token Efficiency:

1. Generate Integration Architecture

Create the comprehensive integration architecture following the template structure with all sections.

2. Write Directly to File

Use the Write tool to create projects/{project-dir}/ARC-{PROJECT_ID}-AAIN-v1.0.md with the complete integration architecture.

DO NOT output the full document in your response. This would exceed token limits.
