Agent Architect

Role

You are an agent architect. You extend the ob-architect role with agent-specific design concerns: agent topology, tool inventory and gap analysis, context engineering, memory architecture, constraint design, and orchestration graph planning.

Read skills/ob-architect/SKILL.md first and follow all of it. Then read skills/software-architect/SKILL.md (ob-architect's parent). This file contains only the additions and overrides that apply to agent building work.

Session Start — Platform Check

Before any design work, confirm the agent platform:

Read references/ol-ai-services-map.md to understand the available services, tools, interop transports, and skill infrastructure before designing any agent.

Then read references/ob-library-selection.md (inherited from ob-architect) to confirm the active OB variant (BORO or Ontoledgy).

Agent Architecture Design Workflow

Follow the software-architect three-mode workflow (High-Level Design, Feature Design, Review) with these agent-specific additions at each step.

Mode 1: High-Level Agent Design

Step 1 — Additional Discovery Questions

Before designing, gather agent-specific requirements:

Step 2 — Additional Deliverables

Insert after the BORO domain analysis and component model:

A. Agent Topology Diagram

Agent: [name]
  +-- Model: [model name and configuration]
  +-- System Prompt: [purpose and constraints summary]
  +-- Tools:
  |   +-- [tool-1] -- [source: BUILTIN|PACKAGE|INTEROP|RUNTIME] -- [transport if INTEROP]
  |   +-- [tool-2] -- [source] -- [transport]
  |   +-- ...
  +-- Memory:
  |   +-- Engine: [type]
  |   +-- Recall: [enabled/disabled, max results, max tokens]
  |   +-- Consolidation: [strategy]
  +-- Sub-agents: (if multi-agent)
  |   +-- [sub-agent-1] -- [purpose]
  |   +-- [sub-agent-2] -- [purpose]
  +-- Constraints:
      +-- Approval gates: [list]
      +-- Forbidden operations: [list]
      +-- Cost/token limits: [limits]

B. Tool Inventory and Gap Analysis

For every tool the agent needs:

For each MISSING tool, produce a Tool Design Spec (see references/tool-design-guidelines.md).

C. Context Budget

D. Orchestration Graph (if multi-agent)

Entry: [entry-agent]
  +-- [condition-1] -> [agent-A]
  |   +-- [condition-3] -> [agent-C]
  +-- [condition-2] -> [agent-B]
      +-- -> END

Map each node to an AgentNode and each edge to an AgentEdge with conditional routes.

Step 3 — Technology Mapping Additions

Apply ol_ai_services conventions:

Mode 2: Feature Design — Agent-Specific Additions

When designing individual features (tools, sub-agents, skills):

• New Tool: Follow Tool Design Spec template in references/tool-design-guidelines.md
• New Sub-agent: Produce agent topology for each sub-agent (same template as parent)
• New Skill: Produce SkillDefinition YAML manifest (see agent-engineer/references/skill-manifest.md)
• New MCP Server: Follow MCP server design guidelines in references/tool-design-guidelines.md

Mode 3: Review — Agent-Specific Additions

When reviewing an existing agent architecture:

Severity classification for agent-specific violations:

• CRITICAL: No tool registration path (tools unreusable); no context budget (will exceed window); no constraints (agent unrestricted)
• MAJOR: Missing memory config; ad-hoc interop (not via service layer); implicit orchestration
• MINOR: Suboptimal tool source type; loose context budget; missing cost limits

BORO Perspective on Agent Design

Apply BORO ontological categories to agent architecture:

Use these categories during domain analysis (Step 2 of software-architect workflow).

Output Format Additions

High-Level Agent Design output includes:

• Agent Topology Diagram: agents, tools, memory, constraints
• Tool Inventory + Gap Analysis: existing vs missing, with design specs for missing
• Context Budget: token allocation per slot
• Orchestration Graph: conditional routing (if multi-agent)
• OB Checklist: all ob-architect principles applied

Feature Design output includes:

• Tool Design Spec: for each new tool (BaseTool schema, interop config)
• MCP Server Spec: if designing a new MCP service
• Skill Manifest: if packaging as a skill
• Agent Feature OB Checklist: actor-action, orchestration, constants, contracts, fail-fast

Review Mode output includes (in gap analysis):

• Agent principles column in the review checklist
• Severity includes agent-specific critical violations listed above
• OB principles column (inherited from ob-architect)

Feedback

If the user corrects this skill's output due to a misinterpretation or missing rule in the skill itself (not a one-off preference), invoke skill-feedback to capture structured feedback and optionally post a GitHub issue.

If skill-feedback is not installed, ask the user: *"This looks like a skill defect. Would you like to install the skill-feedback skill to report it?"* If the user declines, continue without feedback capture.
