Adom DS2SF - Datasheet to Symbol and Footprint

@@ -0,0 +1,206 @@+---+name: adom-ds2sf+description: Datasheet → symbol + footprint + provenance JSON. Reads a chip's datasheet PDF and emits sym_create-shaped symbol JSON, footprint metadata, a field-level provenance audit trail, and an agent-to-agent result.json with stable exit codes for programmatic re-search-and-retry. Trigger words — adom-ds2sf, datasheet to symbol, datasheet to footprint, extract symbol from datasheet, extract footprint from datasheet, datasheet pinout extract, sym extracted json, fp extracted json, datasheet sym fp, chip pin grouping, pin provenance, footprint provenance, sym_create input from datasheet, adom-ds2sf result.json, datasheet extractor agent contract.+---++# adom-ds2sf — datasheet → symbol + footprint + provenance++Pipeline: read a adom-chip-fetcher chip directory, send the datasheet PDF to Claude in two focused passes (symbol → footprint), normalize the package against the service-kicad standard library, and emit four JSON files alongside the existing adom-chip-fetcher artifacts.++## ⚠ Always Opus, never Haiku++Production runs MUST use the default `--model claude-opus-4-7`. EEs rely on this output to wire schematics; Haiku's chip-data misreads are not acceptable in that pipeline. Concur (the cross-source consensus check) does catch most Haiku errors via 4-source consensus, but the right answer is to not produce them in the first place. Override the model only for development experiments where a follow-up Opus pass is acceptable.++## When to use++- After `adom-chip-fetcher` lands a chip into `~/project/adom-chip-fetcher/library/<MPN>/`.+- When you want an Adom-grouped symbol (POWER / I2C / GPIO / etc.) — the UL bundle's `.kicad_sym` is flat and ungrouped.+- When you need a downstream-ready `sym_create` input JSON.+- When you need page-level provenance to deeplink the Adom user back to the datasheet PDF page each fact came from.++## Module products: pass `--pdf` explicitly++For **module products** (ESP32-WROOM, NORA, ATWINC, SARA-R5, etc.), adom-chip-fetcher's auto-named `<MPN>.pdf` may be the internal SoC datasheet — which has the SoC's pinout, not the module's external castellated-pad pinout. The extractor will refuse to hallucinate (writes a result.json with `status: "needs_better_pdf"` and a list of candidate PDFs already on disk).++Look for the module-specific PDF in the chip-dir (`<MPN>-original.pdf`, `<MPN>-datasheethardware-guideline.pdf`, etc.) and pass it via `--pdf`:++```bash+adom-ds2sf extract /home/adom/project/adom-chip-fetcher/library/ESP32-S3-WROOM-1-N4 \+  --pdf /home/adom/project/adom-chip-fetcher/library/ESP32-S3-WROOM-1-N4/ESP32-S3-WROOM-1-N4-original.pdf+```++## Commands++### `adom-ds2sf extract <CHIP-DIR>`++Run the full pipeline against a chip directory.++| Flag | Description |+|------|-------------|+| `--pdf <path>` | Override auto-detected datasheet (default `<dir>/<basename>.pdf`). |+| `--mpn <id>` | Override the MPN. |+| `--manufacturer <name>` | Override the manufacturer. |+| `--datasheet-url <url>` | Override the datasheet URL. |+| `--source-tier <mfr\|snapmagic\|mouser\|digikey\|arrow\|cse\|lcsc\|unknown>` | Override the upstream provenance tier. |+| `--out-dir <path>` | Output directory (default: chip-dir). |+| `--model <id>` | Claude model (default `claude-opus-4-7`). **Always use Opus for production EE work.** Haiku produces frequent misreads on chip data — pin-order swaps (DMG2305 GDS↔GSD), pad undercounts (ICE40UP5K saw 24 of 48), package-variant confusion (WSL2010 → WSL2512), and JTAG-letter typos (MTDO → MTD0). Concur catches these via cross-source consensus, but the right answer is to never let them happen: use Opus.
