Gpu Team

GPU Development Team

Create an agent team for the following task:

Task: $ARGUMENTS

Team structure

The team has five roles:

1. gpu-coordinator — Team lead. Decomposes the task, spawns the four specialists, assigns work, resolves cross-cutting issues, and runs final just check before declaring complete.

2. syskit-specialist — Specification documentation. Keeps requirement, interface, design, and verification docs under doc/ in sync with what the team implements. Updates Spec-ref hashes and maintains traceability.

3. verilog-specialist — SystemVerilog RTL implementation. Works on rtl/components/*/src/ modules. Reads the digital twin first, then implements RTL to match it bit-exactly. Follows .claude/skills/claude-skill-verilog/SKILL.md and .claude/skills/ecp5-sv-yosys-verilator/SKILL.md.

4. rust-twin-specialist — Digital twin implementation. Works on twin/components/*/ crates and integration/gs-twin-srs/. Implements the bit-accurate algorithm in Rust first. Follows .claude/skills/claude-skill-rust/SKILL.md. Generates expected outputs for verification.

5. verification-specialist — Verilator testbenches and synthesis validation. Works on rtl/components/*/tests/ and rtl/tb/. Compares RTL output against twin output using shared .hex stimulus. Follows .claude/skills/claude-skill-cpp/SKILL.md.

Spawning responsibility

The caller spawns all five agents. The coordinator does not spawn anyone.

This is deliberate: the gpu-coordinator subagent's toolset does not reliably expose the Agent tool, so coordinator-driven spawning silently fails. Caller-driven spawning is the only pattern that works.

Caller (top-level Claude that invoked this skill):

1. Call TeamCreate to create the team.
2. Spawn all five agents via the Agent tool, each with team_name set to the team name:
   • name: "coordinator", subagent_type: "gpu-coordinator"
   • name: "twin", subagent_type: "rust-twin-specialist"
   • name: "rtl", subagent_type: "verilog-specialist"
   • name: "verif", subagent_type: "verification-specialist"
   • name: "syskit", subagent_type: "syskit-specialist" Each specialist's initial prompt must end with: "On first wakeup, send a one-line plain-text ack to coordinator (e.g. rtl ready) before doing anything else. Then wait for your assignment."
3. After spawning, use the Read tool on .claude/teams/<team-name>/config.json and confirm all five names appear in members. Any missing name means the Agent call failed — retry it before proceeding.
4. Send the coordinator a briefing message describing the task, the approved in-scope work, and any flagged-only items. The coordinator will dispatch specialists once acks arrive.

Coordinator (once spawned):

1. Read relevant specs and decompose the task. Do not attempt to spawn agents — the caller has already done that.
2. Wait for each specialist to send a plain-text ack before dispatching assignments. If an expected ack is missing after your next turn, escalate to the caller (they may need to respawn).
3. Dispatch assignment messages via SendMessage. Monitor progress, unblock specialists, run final just check, and report back to the caller.

Spawn mechanics — read this carefully

These rules exist because silent failures here are the #1 way this skill wastes a session.

• Only the caller calls Agent to spawn. The coordinator must not attempt it.
• SendMessage does NOT spawn agents. It only writes to an inbox file. Sending a message to a name that was never spawned via Agent is a silent no-op — the message sits in an orphan inbox and nothing reads it. Do not rely on "message sent" as evidence that the recipient exists.
• Verify membership with Read, not Bash. Use the Read tool on .claude/teams/<team-name>/config.json. Do not shell out with cat/jq/python3 — those trigger permission prompts that can stall the session.
• Spawn before message. Never send an assignment message to a specialist that is not present in config.json.

Idle discipline for the coordinator

• Do not go idle immediately after dispatching inbox messages. "Messages sent" is not progress.
• Never end a turn on a failed or denied tool call. If a tool call is denied, errors, or stalls (permission prompt, missing tool, unexpected result), your very next action in the same turn must be a concrete progress step — usually a Read, a SendMessage, or an escalation to the caller describing what's blocked. Do not go idle right after a failure.
• Only go idle when one of the following is true:
  • All spawned specialists have acknowledged AND work is actively in flight (you are waiting on a named specialist's reply).
  • You are blocked on the caller for a decision and have already asked the caller a specific question.
  • Work is complete and you have reported the final result to the caller.
• If you catch yourself about to go idle without progress, instead: re-check config.json via Read, re-check inboxes, and take the next concrete action (re-send a prompt, ask the caller to respawn a missing specialist, or escalate).

Workflow

The team follows this order:

1. Coordinator reads relevant specs (doc/design/, pipeline/pipeline.yaml, ARCHITECTURE.md) and decomposes the task
2. Rust-twin-specialist implements or updates the twin algorithm (this defines the expected behavior)
3. Verilog-specialist implements RTL to match the twin (can start in parallel if the twin interface is stable)
4. Verification-specialist writes testbenches and runs RTL-vs-twin comparison
5. Syskit-specialist updates docs under doc/ to reflect what was implemented, stamps Spec-ref hashes
6. Coordinator runs just check and confirms all tests pass

Rules

• The digital twin is the authoritative algorithm spec — RTL must match it
• Shared .hex stimulus files feed both twin and RTL testbenches
• pipeline/pipeline.yaml must be updated before adding new pipeline units
• All code must pass just check (Verilator lint, cargo fmt, cargo check, cargo clippy)
• The syskit-specialist keeps docs in sync with implementation — no formal syskit workflow needed
• The caller owns spawning; the coordinator owns dispatch, monitoring, and the final just check
• The coordinator must obey the idle-discipline rules above — never end a turn on a denied/failed tool call, and never go idle without progress
