p2-arch-design-policy

p2-arch-design-policy is a skill for Claude Code from babyworm/rtl-agent-team. It costs 23 tokens per session (2,584 once invoked), scanned A, original, MIT.

An internal policy reference defining how to review a hardware architecture. It sets review criteria for gate count, timing, memory, bandwidth, throughput, implementation risk, and consistency with a C reference model.

In plain words
What is it for?
It supports review of algorithm choices and architecture candidates during Phase 2 of an RTL design.
Why use it?
It gives architecture reviewers a shared checklist for judging feasibility and finding structural or modelling problems.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

p2-arch-design-policy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Phase 2 Architecture Design Policy

P1 Algorithm Candidate HW Review Criteria

For each functional area's candidates from P1's domain-analysis.md, evaluate:

  • Gate count estimate (from literature or analytical estimation)
  • Critical path depth (combinational logic levels)
  • SRAM requirements (capacity, banking, port count)
  • External memory bandwidth (bytes/pixel, access patterns)
  • Achievable throughput at target frequency (pixels/cycle, blocks/cycle)
  • Implementation risk (tool support, verification complexity, proven vs novel)

Architecture Review Criteria (Dynamic Convergence Protocol)

Dynamic convergence review (min 2, max 5 rounds), coordinated by rtl-architect:

  • 3 mandatory parallel reviewers each round: (a) rtl-architect: spec compliance (Feature Coverage Checklist) + structural review (b) vcodec-architecture-expert: memory access patterns, performance analysis (c) ref-model-dev: architecture ↔ C model consistency (block mapping, data flow, interfaces)
  • +1 conditional reviewer: (d) ref-model-reviewer: independent C model quality gate (algorithm fidelity, numerical precision, undefined behavior/build warning risk) when ref model is newly created or substantially revised
  • ref-model-reviewer activation threshold: Invoke when ref model is newly created OR

    30% of source lines changed from prior version. Both sequential and team orchestrators use this same threshold. Skip review tasks when ref model is unchanged.

  • Each round: review → rebuttal (designer accepts/rejects each finding with rationale) → tree exploration for issues → targeted revision (rejections recorded in per-round artifact)
  • Last round (converged or max reached): cross-block interface audit + memory conflict analysis
  • Convergence check after round >= min_rounds: finding_delta < 0.1, all critical resolved, wonder stable
  • After max_rounds if not converged → escalate to user via AskUserQuestion

Architecture Naming Conventions

  • Block names: snake_case (become RTL module names in Phase 4)
  • Interface descriptions: data width, protocol type, direction — NOT RTL port naming
  • RTL naming conventions (i_/o_ prefix, clock/reset naming) applied in Phase 4, not here

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

p2-arch-design-policy is a skill published in the GitHub repository babyworm/rtl-agent-team (51 stars, last pushed 18d ago), licensed MIT. It adds 23 tokens to every session and 2,584 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
