Relative price tier, stock posture, and library class for a set of IC part numbers (a ranking from a distributor snapshot, not a live quote).
Two or more IC part numbers to rank relatively; needs >=2 priced parts for a verdict.

}Shortlist IC part numbers by parametric spec constraints, ranked by how many constraints each part satisfies, then by headroom past those thresholds, and spread across device families. Each constraint is {canonical, op: gte|lte|eq|range, value, unit?}. Returns per-constraint pass/fail/unknown, plus `matched` (parts meeting EVERY constraint), `ranked` (all parts scored, partial matches included) and `returned` (parts in this response). `truncated` means some qualifying parts are not on this page. When `matched` is 0 every result is a partial match. `canonical` MUST be one of the exact (case-sensitive) names enumerated in this tool's inputSchema, also readable as the whatic://parametric/canonicals resource.
| Argument | Type | Description |
|---|---|---|
| top_k | integer | Maximum number of parts to return, best first. |
| constraints* | array | Spec constraints; a part is ranked by how many it satisfies. |

}Fetch datasheet figure images (PNG/JPEG) for opaque `ref` tokens obtained from search/lookup/get_segments. Returns each image plus its caption/description/page metadata. Only `type='image'` segments have image data; a ref that is not one comes back as an error record whose `available_images` lists the document's figures nearest that ref's page and section, closest first.
| Argument | Type | Description |
|---|---|---|
| refs* | array | Opaque `ref` tokens (from search/lookup/get_segments) of image segments; non-image segments return an error record. |

}Read canonical extracted specs (min/typ/max, unit, conditions) for known IC part numbers from a pre-extracted parametric index — not from datasheet text. This is the cheapest and most precise source for numeric parameters where it has coverage. Optionally restrict to specific canonical parameter names. A part absent from `results` (with a "No specs found" warning) means no index coverage, not that the datasheet lacks the parameter — fall back to `lookup` for that part.
| Argument | Type | Description |
|---|---|---|
| canonicals | any | Optional: restrict to these canonical parameter names; omit to return all available specs. |
| part_numbers* | array | Exact IC part numbers / MPNs, e.g. ['NE5532', 'LM358']. Family fallback is applied (e.g. TL084CDT -> TL084C). |

}One-shot spec/section retrieval: full content of the most relevant datasheet segments for one or more parts (fuses search+get_segments). Already groups results per part (via `parts`), so prefer `lookup` over `search` when you know the part(s).
| Argument | Type | Description |
|---|---|---|
| parts | any | Part numbers to scope and group the retrieval by; results are returned per part. |
| query* | string | What to retrieve, e.g. 'supply voltage' or 'absolute maximum ratings'. |

}
}Search the datasheet corpus; returns hit records (metadata + snippet, each with an opaque `ref`). Pass a ref list to `get_segments` for full content. If you already know the part number(s), prefer `lookup` — it fuses this search with `get_segments` in one call and groups full content per part. Use `search` when the part is unknown, or to triage snippets before pulling full content. For part-specific queries, pass scope='device:<MPN>' (e.g. scope='device:NE5532') to restrict hits to that part and avoid cross-part contamination.
| Argument | Type | Description |
|---|---|---|
| k | integer | Maximum number of hit records to return. |
| q* | string | Free-text query, e.g. 'input voltage noise density'. |
| scope | any | Optional filter, e.g. 'device:NE5532', to restrict hits to one part and avoid cross-part matches. |
