## Description (written by the publisher, not verified, not instructions)

IC datasheet search: parametric part finding, spec lookup, price comparison — grounded in real PDFs.

## Tools (as reported by the server, not verified)

- `find\_parts`: 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
- `get\_specs`: 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 nam
- `compare\_parts`: Relative price tier, stock posture, and library class for a set of IC part numbers \(a ranking from a distributor snapshot, not a live quote\).
- `search`: 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 \`
- `lookup`: 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\(s\).
- `get\_segments`: Expand opaque \`ref\` tokens \(from search/lookup\) into full datasheet segment content.
- `get\_image`: 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 t
