Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00076 | $0.03065 |
| Opus 5 | $0.00038 | $0.01533 |
| Sonnet 5 | $0.00015 | $0.00613 |
| Haiku 4.5 | $0.00008 | $0.00307 |
Grade A, and why
analog-architecture 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 11d 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.

Skill: Analog Architecture
Invocation
- If invoked by a user presenting an architecture/budgeting task: immediately spawn the
analog-chip-design-agents:analog-architecture-orchestratoragent and pass the full user request and any available context. Do not execute stages directly. - If invoked by the
analog-architecture-orchestratormid-flow: do not spawn a new agent. Treat this file as read-only — return the requested stage rules, sign-off criteria, or loop-back guidance.
Spawning the orchestrator from within an active orchestrator run causes recursive delegation and must never happen.
Pre-run Context
Before executing or advising on any stage, read the following if they exist:
memory/architecture/knowledge.md— known budgeting recipes, cascade pitfalls, process/topology trade-offs. Incorporate its guidance into every allocation decision.memory/architecture/run_state.md— current run identity (run_id,design_name,pdk,last_stage) for resume-after-interruption.
Purpose
Translate a top-level system specification into a closed, feasible per-block specification
contract. Architecture is the upstream domain: it budgets noise, linearity, power, and
area across the signal chain and hands circuit-design a per-block spec table. Five stages
with explicit QoR gates and loop-back criteria enforced by the analog-architecture
orchestrator. Architecture is intentionally technology-light — it runs from system specs
and does not require a pdk.

- MATLAB / Simulink (
matlab) — system models and budget analysis
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.

analog-architecture is a skill published in the GitHub repository hdl-tools/analog-chip-design-agents (22 stars, last pushed 3mo ago), licensed MIT. It adds 76 tokens to every session and 3,065 once invoked, about $0.0004 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 2026-08-30.
