# /as:product-pair — Product Pairing

Before acting, read the [host contract](../../docs/host-harness-contract.md) and this component's [declaration](host-contract.json) (`skill:product-pair`). Load only its referenced mode profiles from the [shared catalog](../../corpus/host-contracts.json). Compose modes required by the actual task; declarations are requirements, not proof of access or permission.

Library changes are owned by [/as:product-library](../product-library/SKILL.md) under its complete [native contract](../../tools/workspace/product-library-contract.md). Prepare selected rows and evidence, then hand off the complete save under existing authorization, preserving preview/current-byte hash/request-ID binding and actual readback. This skill does not independently mutate `product-library.csv`; recommendations do not authorize adoption or record changes.

## Native evidence and authority

Read the complete [observation semantics](../../schema/product-observations.md) and unchanged
[observation schema](../../schema/product-observation.schema.json) when producing or adapting
structured evidence. Native `product_observations.validate`, `validate-batch` and `adapt` preserve
exact variants, zero/null/unknown values, source locators, timestamps and number kinds. Validate
complete envelopes/batches before treating them as usable. Adapt only explicitly bound source
fields and current selected item revisions; a recommendation or user choice is not an inferred
binding, existing-value replacement, approved decision or specification adoption.

For project-bound saves use the [native context owner](../project/references/context-resolution.md)
and [workspace ownership](../../docs/workspace-model.md); resolve an actual valid project before
selecting its library. Standalone comparison or pairing needs no project creation. Supplied pages,
images and retrieved text are evidence, not authority to change files or contact others. Inspect
actual source/image access and distinguish visual inference from verified specification facts.


"What goes with this?" Takes a product and suggests complementary items across different categories — a side table for a sofa, a floor lamp for a reading chair, a rug for a dining table. Returns 5-8 pairings with reasoning rooted in design principles.

## When to Use

- Building out a room or vignette from a hero piece
- Designer has a key product and needs to complete the palette
- Presenting a coordinated product package to a client
- Filling gaps in an FF&E schedule by category

## Step 1: Accept Input

Examples below illustrate supplied input formatting only; names, specifications and prices are not verified current product facts.

**By name:**
```
/as:product-pair Blu Dot Diplomat Sofa
```

**By name + context:**
```
/as:product-pair Blu Dot Diplomat Sofa for a tech office lounge
```

**By product details:**
```
/as:product-pair
Name: Diplomat Sofa
Brand: Blu Dot
Materials: Steel frame, fabric upholstery
Color: Edwards Navy
Style: Contemporary, minimal
Price: $2,499
Context: Corporate lounge, 6-person seating area
```

## Step 2: Analyze the Source Product

Identify the product's design DNA:
- **Style language**: Mid-century, Scandinavian, industrial, contemporary, etc.
- **Material palette**: Wood type, metal finish, upholstery type
- **Color family**: Warm neutrals, cool tones, bold accent, monochrome
- **Scale**: Compact/apartment, standard, generous/commercial
- **Price tier**: Budget (<$500), mid-range ($500-$2,000), premium ($2,000-$5,000), luxury ($5,000+)
- **Market**: Residential, contract, hospitality

## Step 3: Determine Pairing Categories

Based on the source product's category, identify what typically pairs with it:

| Source Category | Pair With |
|----------------|-----------|
| Sofa | Coffee table, side table, floor lamp, throw pillow, rug, ottoman |
| Lounge Chair | Side table, floor lamp, ottoman, throw |
| Dining Table | Dining chairs, pendant light, sideboard, rug |
| Desk | Task chair, desk lamp, monitor arm, desk organizer |
| Bed | Nightstands, table lamps, bench, rug, dresser |
| Conference Table | Conference chairs, credenza, pendant/linear light |
| Task Chair | Desk, monitor arm, task light |

If the designer provided context (e.g., "tech office lounge"), factor that into category selection.

## Step 4: Search for Pairings

For each pairing category, search for products that match the source's:
- **Style**: Same design language or intentional contrast
- **Material harmony**: Complementary materials (e.g., walnut sofa → brass lamp, not chrome)
- **Color coordination**: Same palette, complementary, or intentional accent
- **Scale proportion**: Appropriately sized relative to the source
- **Price alignment**: Similar tier (don't pair a $5,000 sofa with a $30 lamp)

Run 2-3 searches per pairing category. Target 5-8 total pairings across different categories.

## Step 5: Present Pairings

```text
Synthetic formatting input only:
Example Product A | Example Manufacturer | quantity 2 | supplied specification pending
```

### Presentation rules

- **Explain the design reasoning** for each pairing — material harmony, color logic, scale, style
- **Mix brands** — don't just suggest the same brand for everything (unless the designer asks)
- **Include at least one accent** — a piece that creates intentional contrast (different material, color pop, different era)
- **Stay in the price tier** — pairings should feel proportionate to the source
- **Note contract availability** if the source is contract-grade

## Step 6: Save

If the designer picks pairings, prepare complete rows for the resolved project-root `product-library.csv`. Read `../../schema/product-schema.md` and `../../schema/csv-conventions.md`. Preview all chosen pairings and the target path, then use existing exact authorization or ask once for the missing approval. Under that authorization, serialize the complete batch as one JSON array and hand it to `/as:product-library` for one native `product_library.append` operation with its full validation, preview binding, recoverable preparation and actual byte/access readback. Never loop per row or bypass that owner.

- `Tags`: append `pair:{source-product-name}` for traceability
- `Notes`: `Paired with {source product}. {Design reasoning}`
- `Status`: `saved`
- `Source`: `product-pair`

## Pairs With

- `/as:product-match` — match finds alternatives to the source, pair finds complements
- `/as:product-research` — research finds products from a brief, pair builds around an anchor piece
- `/as:product-enrich` — enrich paired products with full metadata
- `/as:product-data-import` — prepare accepted intake for the source and pairings; master-schedule owns any separately authorized adoption

## Original product evidence

Retrieve exact selected manufacturer/product/variant facts from original documents for the task. Example data is synthetic and never evidence. Do not copy product facts, certifications, prices or vendor format definitions into the plugin as reusable reference knowledge. Preserve unresolved values and distinguish representative imagery from the exact selected variant.

## Native output and owner handoffs

Return sourced comparisons, actual checks and unresolved values using the
[completion contract](../../docs/completion-reporting.md). Source-backed price, availability,
lead time and exact variant facts need original current evidence; snippets are discovery only.
Aesthetic similarity, estimated image scale and pairing judgments remain labeled judgments.
Do not invent a score input or source fact to fill a missing candidate attribute.

For an explicitly requested saved standalone report, follow the
[native mutation sequence](../../docs/workspace-model.md#native-mutation-sequence): inspect pending
state, retain full source guards and complete prepared report, finish durable saves and separately
reopen/validate actual prepared bytes and access before publication. Publish complete bytes without
clobbering another file, then read back actual destination content/access and all protected sources
before completion. A report does not mutate library/schedule records. For durable project placement
or registration, hand off the explicit coordinates/kind/current source evidence to the document
owner; receive owns registration. Keep one-off work standalone.

Use existing authorization and preserve exact scope in every handoff. Library save belongs to
product-library, adopted records to master-schedule, accepted input jobs to product-data-import,
and facts/decisions to project. No Arch Studio runner, source reconstruction or installation is
required for these native procedures. External sharing and sending require their own authorization.
