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 | $0.00237 | $0.00237 |
| Opus 5 | $0.00118 | $0.00118 |
| Sonnet 5 | $0.00047 | $0.00047 |
| Haiku 4.5 | $0.00024 | $0.00024 |
Grade A, and why
analog-chip-design-agents copilot-instructions.md 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.
What it actually says
Analog Chip Design — Copilot Workspace Instructions
This workspace contains analog / mixed-signal + RF chip design work spanning 16 domains: architecture, behavioral modeling, circuit design, circuit simulation, AMS verification, custom layout, physical verification, parasitic extraction, post-layout sign-off, reliability, characterization, RF design, EM modeling, AMS integration, infrastructure, and pipeline orchestration.
Behaviour for All Domains
- Apply domain-specific QoR metrics before declaring any stage complete.
- Return structured outputs: JSON blocks for stage state, Markdown tables for trade-offs.
- Execute one stage at a time and report PASS / FAIL / WARN after each stage.
- Flag ambiguities before proceeding — chip design is safety-critical.
- When a stage loop limit is exceeded, escalate to the user with full state and recommendations.
Domain-Specific Rules
Per-domain rules, QoR metrics, and stage sequences are loaded from
.github/instructions/<domain>.instructions.md based on the files you are working with.
These files are generated from the plugin SKILL.md sources and contain the full
domain knowledge for each analog/mixed-signal + RF design stage.
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-chip-design-agents copilot-instructions.md is an instructions file published in the GitHub repository hdl-tools/analog-chip-design-agents (22 stars, last pushed 3mo ago), licensed MIT. It adds 237 tokens to every session, about $0.0012 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.
