MANDATORY entry point when `design_one_shot_runner.step_rtl_gen` WAIVES with `fallback_skill='spec-to-rtl'`. This is invoked for every IC class with `rtl_gen=null` in `ic_class_registry.json`, which is the SOURCE OF TRUTH for that set and the thing the runner actually routes from -- at the time of writing the 11 such classes are bare_fpga, bus_interconnect_protocol, bus_peripheral, crypto_accelerator, data_converter, digital_arithmetic_primitive, digital_cmd_driven, processor_cpu, pure_analog…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# spec-to-rtl — the runner-orchestrated AI authoring step ## What this skill IS The deterministic authoring path for IC classes WITHOUT a registered `rtl_gen` generator. Spec → RTL fundamentally requires a language model (open-benchmark- methodology skill § 1); this skill is **how the runner delegates that step to the AI inside its own pipeline**, so the surrounding gates still fire. ## Invocation contract When `design_one_shot_runner.step_rtl_gen` WAIVES with the message: > *IC class 'XXX' registered but rtl_gen=null. Recommended action: AI invokes > skill `spec-to-rtl`.* …the AI MUST: 1. **Read the input contract named by the runner handoff**. For the explicit bounded D09 position 17 `input_authority=original` contract, read the **entire** `read_prompt_from` file and every `read_context_from` file. Verify their recorded SHA-256 values before authoring or reviewing. These are the authoritative source bytes; do not substitute generated Ldocs or require a D01 position 1 document review for this RTL-only request. A changed or missing source requires returning to the ordinary runner, not silently adopting it. This …

How to install
mdr add vibeic/vibe-ic/spec-to-rtl@sha256:2955996585d4e6cfThe line at the top of this page pins the label git:20261104.abf79c3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
