description

Streamlined single-pack design grilling for agent stacks, architectures, and plans — the opinionated quick path with a unified CLI and A2A transport. Use for branch-by-branch resolution of a multi-agent collaboration, subagent topology, fleet roster, or complex plan when you want the consolidated athenaeum protocol. Triggers — "athenaeum design", "design via athenaeum", "athenaeum grill the plan". If the grill-each-other pack is installed and you want modular primitives instead, use grill-me (generic plans) or grill-me-agents (agent topology).

Athenaeum — Design

Decide what you're grilling

Agent stack? Use the 13-branch audit (see REFERENCE.md §1). Output: AGENT_DESIGN.md. Generic plan / feature / ADR? Use the lightweight 5-branch grill (§2). Output: DESIGN.md.

Quick start

1. Scan the repo — read existing agent definitions, skills, settings, and any prior AGENT_DESIGN.md. Propose answers from ground truth rather than asking from scratch.
2. Ask one question at a time. Walk the branches in order. Do not descend until the current branch is concrete, not a placeholder.
3. Push back on vagueness. If the answer is fuzzy, cite the specific edge case or file that makes it fuzzy.
4. Write the design doc when every branch is resolved. Use the template in templates/design/.

Agent-stack branches (13)

#	Branch	What to settle
1	Goal & success criteria	Outcome and done-condition
2	Agent roster	Who exists, single responsibility per agent
3	Topology	Orchestrator, pipeline, peer-to-peer, or state-machine?
4	Context boundaries	What each agent sees and why
5	Handoffs & contracts	Exact input/output schema between agents
6	Shared state	Mutable persistence — store, schema, writers, TTL
7	Tool access	Which agent gets which tools; blast radius
8	Per-agent failure modes	Loops, refusals, timeouts; who detects/recovers
9	Inter-agent disagreement	Precedence rules when agents contradict
10	Human-in-the-loop	When the user is pulled in; minimum context needed
11	Termination	What stops the collaboration
12	Observability	Logging, tracing, replayability
13	Cost & latency	Token budgets, wall-clock, what gets cut first

Generic-plan branches (5)

1. Goal & success criteria
2. Scope & boundaries
3. Risks & failure modes
4. Dependencies & sequencing
5. Verification — how do we know it's right?

Templates

• templates/design/AGENT_DESIGN.md.template — agent stack
• templates/design/DESIGN.md.template — generic plan

A2A interop

This skill speaks A2A natively. An A2A Task represents this workflow.

Task metadata:

• athenaeum_mode: design
• status lifecycle: submitted → working → input-required → completed

Artifacts produced:

• DESIGN.md — text/markdown
• AGENT_DESIGN.md — text/markdown (agent-stack audits)

Enable A2A for this workflow:

athenaeum init my-topic --mode design --transport a2a

Invoking via A2A:

{
  "jsonrpc": "2.0",
  "method": "tasks/send",
  "params": {
    "task": {
      "id": "athenaeum-design-my-topic",
      "sessionId": "<agent-session>",
      "status": "submitted",
      "metadata": {"athenaeum_mode": "design", "topic": "my-topic"}
    }
  }
}

Sibling skills

• athenaeum-reconcile — two+ agents reconciling divergent state
• athenaeum-ratify — fleet-wide attestation of a frozen artifact
