/as:product-match — Product Match

Before acting, read the [host contract](../../docs/host-harness-contract.md) and this component's [declaration](host-contract.json) (`skill:product-match`). 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.

<!-- architecture-studio:harness-compatibility --> > Read [actual host delivery guidance](../../docs/host-adapters.md). Use available native research, > image and file tools; operation names identify semantic work, not an installed executable.

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.

"Find me something like this." Takes a product — by name, image, or description — and searches the web for similar alternatives. Returns 5-10 matches with specs, pricing, and links.

When to Use

• Designer has a product they like but it's over budget, discontinued, or wrong lead time
• Client references a product and you need alternatives at different price points
• Sourcing a similar product from a different manufacturer or region
• Finding contract/trade equivalents of residential products (or vice versa)

Step 1: Accept Input

The designer provides a product reference in any format:

**By name:**

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

**By name + constraints:**

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

**By image:**

/as:product-match ~/Downloads/chair-photo.jpg

**By description:**

/as:product-match mid-century lounge chair, molded plywood shell, leather cushions, swivel base

**By URL:**

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

Step 2: Identify the Source Product

If given a name or URL, look up the product's key attributes:

• Category and subcategory
• Dimensions (W, D, H)
• Materials and finishes
• Price range
• Designer / design era
• Key visual characteristics (silhouette, proportions, details)

If given an image, use the available host’s image inspection to describe:

• Product type and category
• Shape, proportions, silhouette
• Materials visible (wood type, metal finish, upholstery)
• Style period and design language
• Color palette
• Estimated scale

If given a description, extract the same attributes from the text.

Document the source product clearly:

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

Step 3: Search for Matches

Run 3-5 web searches targeting different angles:

1. **Direct alternatives**: `lounge chairs similar to Eames` 2. **Category + style**: `mid-century molded plywood lounge chair` 3. **Price-specific** (if budget mentioned): `modern lounge chair under $3,000` 4. **Material-specific**: `leather and walnut lounge chair swivel` 5. **Trade/contract sources**: `contract lounge chair molded wood specification`

For each candidate found, attempt to fetch the product page for full specs.

**Target: 5-10 matches** that genuinely resemble the source. Quality over quantity.

Step 4: Score and Rank Matches

For each match, assess similarity on:

• **Visual similarity** (0-5): Does it look like the source?
• **Material match** (0-3): Same or similar materials?
• **Price proximity** (0-3): Within a reasonable range of source or stated budget?
• **Dimension match** (0-2): Similar scale?
• **Availability** (0-2): In stock or reasonable lead time?

Total score out of 15. Present in descending order.

Step 5: Present Results

Presentation rules

• Lead with the comparison table for quick scanning
• Include "Why" for each — what makes
