rat-dse-policy

rat-dse-policy is a skill for Claude Code from babyworm/rtl-agent-team. It costs 20 tokens per session (3,057 once invoked), scanned A, original, MIT.

An internal policy for design space exploration, the process of comparing multiple hardware algorithms and architectures before choosing one.

In plain words
What is it for?
Use it to guide hardware architecture comparisons and iterative exploration before RTL implementation.
Why use it?
It defines how to compare candidates, study trade-offs such as precision, area, and performance, and record the reasoning behind a choice.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

rat-dse-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 7d 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.

DSE Policy

What Makes DSE Different from Standard Phase 1→3

Aspect Standard (p1 + p2 + p3 sequential) rat-dse
Algorithm study Select best, justify Explore N candidates, quantitative comparison
Architecture Single architecture from requirements Multiple candidates, trade-off matrix, user selects
μArch + BFM Single-pass μArch design Iterative μArch with self-critique and re-exploration
Ref C model Build from scratch Accept functional model as input, transform to architectural model
Fixed-point Identify precision requirements Simulate effects, precision vs area trade-off curves
Iteration One-shot per phase Self-critique → re-run → user review → trial comparison
Output Ready for Phase 4 Pre-implementation package with DSE rationale, ready for Phase 4

Design Priority Order

  1. Functional Correctness (highest) — Every required feature works exactly
  2. Interface Compliance — Ports, protocols, timing match Architecture
  3. Timing/Performance — Throughput, latency targets met
  4. Area/Power (lowest)

Document-as-Memory

All exploration results captured in design artifacts (docs/, reviews/) so downstream phases can reference DSE rationale without repeating exploration.

DSE Methodology

Algorithm Comparison Matrix (per functional block)

For each major functional block, enumerate 2-4 algorithmic approaches:

Metric Candidate A Candidate B Candidate C
Computational complexity (ops/input)
Memory access pattern (seq/random, R/W ratio)
Memory bandwidth estimate
HW gate count estimate (order of magnitude)
Quality/accuracy impact (PSNR/SSIM if applicable)
Parallelization potential (data/pipeline)

Fixed-Point Feasibility Analysis

  • Minimum bit-width for acceptable precision
  • Rounding mode impact (truncate vs round-half-up vs convergent)
  • Precision vs area trade-off (e.g., 12-bit vs 16-bit internal paths)

What this file has done since we first saw it

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.

rat-dse-policy is a skill published in the GitHub repository babyworm/rtl-agent-team (51 stars, last pushed 18d ago), licensed MIT. It adds 20 tokens to every session and 3,057 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.
