description	Discovers and documents the source platform schema (entities, fields, relationships) for a migration project. Use when capturing source structure before mapping to Wix.

rp-discovery

Discover and document the source-platform schema for the active migration project.

Purpose

Use this skill to inspect the source system, identify entities, relationships, fields, identifiers, media, rich content, and platform-specific constraints. Examples include Shopify, WordPress, WooCommerce, and custom CMS platforms.

This skill owns the platform-agnostic discovery process and its output contract (source-profile.md + source-schema.json). Platform-specific details — how to capture a given source, its auth model, REST quirks — live in a dedicated source adapter skill, not here. For WordPress / WooCommerce, that adapter is rp-source-wordpress. To support a new platform, add a sibling adapter (e.g. rp-source-shopify) and leave this skill unchanged.

Inputs

Expected inputs may include:

• source platform name
• source API docs or exports
• credentials, tokens, or local dump files when available
• current project under migrations/<project>/
• project-local config under migrations/<project>/config/

Config gate before capture

Before running source capture, verify the project-local config files created by rp-orchestration:

• config/wix.env should always exist with WIX_SITE_ID and WIX_AUTH_TOKEN keys, even though discovery itself may not use Wix credentials yet.
• config/source.<platform>.env should exist once the source platform is known. For WordPress this is config/source.wordpress.env.

If a required key is missing or blank, ask the user for that value and fill the config file for them before continuing. Ask one value at a time. Never print secret values back to the user; report only present/missing.

Treat migrations/<project>/config/*.env as secret-bearing once they may contain real values. Do not inspect them with whole-file reads that echo contents into tool output. Use secret-safe checks only: existence, required key names, and present / blank / missing status.

Workflow

1. Confirm the active project under migrations/<project>/.

2. Identify the source platform and acquisition method, then select the matching source adapter skill (e.g. rp-source-wordpress for WordPress / WooCommerce). If no adapter exists for the platform, capture entities manually following the same output contract.

3. Run the adapter's capture step to produce a raw, machine-captured dump under <migrations-root>/<project>/data/<source>-discovery/. For WordPress, the capture script lives in rp-source-wordpress/scripts/ — run it from that skill directory (see rp-source-wordpress Capture section and CONVENTIONS.md). The adapter owns the capture mechanics, auth model, and platform quirks; this skill consumes its output.

   • Distinguish supported entities (advertised by the source) from used entities (those with recordCount > 0). Entities advertised but empty should be flagged, not mapped as if they hold data.
   • A capture made without credentials is usually incomplete (gated entities, private fields, PII return 401/403). Do not treat an unauthenticated capture as authoritative — the adapter documents what auth a complete run requires.

4. Capture field-level schema details, including type, cardinality, requiredness, and example values.

5. Note operational constraints such as pagination, rate limits, auth model, and incremental sync options. If the source base URL or discovered media/file URLs use localhost, 127.0.0.1, or another private-only host, record a media reachability note in source-profile.md. Localhost is fine for discovery and local source reads, but Wix Media import is URL-based and Wix servers cannot fetch the user's localhost. This is an optional preparation step and, as far as we know today, only affects media import. State the two acceptable choices:

   • expose the source with a public HTTPS tunnel such as ngrok before live media import
   • skip/defer media import while continuing non-media entities

   Include concise ngrok setup instructions when relevant:

   brew install ngrok
   ngrok config add-authtoken "<YOUR_AUTHTOKEN>"
   ngrok http 8090
   export WP_BASE_URL=https://<id>.ngrok-free.app
   

6. Synthesize the raw capture into the normalized artifacts below.

Artifacts to create or update

• migrations/<project>/data/<source>-discovery/: raw machine-captured output from the source adapter. Treated as evidence, not a hand-off artifact — downstream skills reference it for traceability but do not read it wholesale.
• migrations/<project>/source-profile.md: source platform, access method, limits, auth, and operational notes. Synthesized from the raw capture. Capture the operational facts the adapter documents (auth model, pagination, rate limits) so rp-import-codegen has them without re-deriving.
• migrations/<project>/source-schema.json: machine-readable schema for entities and fields. Synthesized from the raw capture — this and source-profile.md are the canonical hand-off to rp-mapper. Include traceability pointers so the mapper can drill into a specific entity's raw file when needed:
  • top-level rawDiscovery: relative path to the raw capture dir, e.g. data/wp-discovery/.
  • per-entity rawFile: file name within that dir, e.g. wp-v2--posts.md.
  • per-entity recordCount and inUse so consumers can distinguish supported vs. actually-used entities.
  • per-entity relations derived from the source-declared relationships in the raw capture, so relationships are evidence-backed rather than guessed. Each relation should carry an evidence pointer back to the source signal it came from.
  • Follow the adapter's source-schema.example.json for the shape (e.g. rp-source-wordpress/source-schema.example.json). It is a template to follow, not a strict schema to validate against — keep the platform-agnostic core stable and push platform quirks into each entity's open sourceMeta blob.
• Optional supporting notes under migrations/<project>/research/ if needed.

Output quality rules

• Separate confirmed facts from assumptions.
• Record per-entity volume (record counts) so downstream skills know what the site actually uses, not just what it supports.
• Preserve source-specific identifiers exactly.
• Include enough detail for downstream mapping and code generation.
• Flag unknowns explicitly instead of inventing structure.
