fix: relax over-strict validation_rules() so abilities accept minimal input by superdav42 · Pull Request #755 · Ultimate-Multisite/ultimate-multisite

Summary

The MCP *-create-item abilities (registered via trait-mcp-abilities.php) read each model's validation_rules() to build their JSON Schema and mark fields as required. Several models flagged fields that are either WaaS-specific extras (customer_id, membership_id on a default WP subsite), the only valid value (type on customer), or already had sensible model-level defaults that made required redundant.

Result: AI callers (and any other programmatic caller of wu_create_*) had to supply ~6 fields to create a vanilla WP subsite when only 4 are genuinely needed, and similar for the other entities. Weak LLMs would either guess wrong values or fall back to db-query / run-php hacks.

This PR removes 11 spurious required flags across 7 models, adds explicit default: rules where one was missing, fixes a related bug in wu_create_product that prevented model-level defaults from firing, and fixes a subdomain-mode routing bug in wu_create_site.

Companion PR in Ultimate-Multisite/gratis-ai-agent#807 adds the auto-discovery layer that surfaces these abilities to the agent in the first place — together they make it possible for an LLM agent to create a Multisite Ultimate subsite from a one-line prompt.

Why

When an LLM agent sees the create-item schema for these models, every required field forces it to either guess a value or call a fetcher ability first. For the genuine fields (title, customer_id on a payment) that's fine — for spurious ones it's pure friction. The same applies to humans writing scripts against wu_create_*.

The site model in particular: a vanilla WordPress subsite (type: default) doesn't need a customer or membership — those are WaaS-specific concepts. Forcing them required the agent to walk a four-call workflow (list customers → list products → create membership → create site) just to reach a regular blog. With this PR a single site-create-item call with {title, name, path, type} suffices.

Per-model changes

Site (`inc/models/class-site.php`)

Field	Was	Now
`site_id`	`required\|integer`	`integer\|default:1`
`description`	`required\|min:2`	`default:`
`customer_id`	`required\|integer\|exists:...`	`integer\|default:\|exists:...`
`membership_id`	`required\|integer\|exists:...`	`integer\|default:\|exists:...`

title, name, path, type remain required (genuine WordPress minimum). The exists: foreign-key check still fires when a value is supplied so customer-owned sites still validate correctly.

Subdomain mode (`inc/functions/site.php`)

wu_create_site() now detects subdomain multisite installs and auto-converts a supplied path slug into the correct subdomain ({slug}.{network-domain}) when no explicit domain was given. The existing wu_get_site_domain_and_path() helper does this conversion but wu_create_site() never used it — programmatic callers passing path: "blog" on a subdomain install ended up with an unroutable site row at <network>/blog. Subdomain/subdirectory mixing still works because callers that pass an explicit non-root domain are respected as-is.

set_domain() and set_path() doc comments rewritten to make the mode-aware behaviour explicit so any tool that surfaces field descriptions to an LLM (or any human reader) gets the right guidance.

Customer (`inc/models/class-customer.php`)

Field	Was	Now
`email_verification`	`required\|in:none,pending,verified`	`in:...\|default:none`
`type`	`required\|in:customer`	`in:customer\|default:customer`

type only ever accepts one value, so requiring callers to specify it is pure friction.

Product (`inc/models/class-product.php` + `inc/functions/product.php`)

Field	Was	Now
`currency`	`required\|default:{site_currency}`	`default:{site_currency}`
`pricing_type`	`required\|in:free,paid,...`	`in:...\|default:free`
`type`	`required\|default:plan\|in:...`	`default:plan\|in:...`

Bonus fix in wu_create_product(): the helper pre-filled missing fields with false sentinels via wp_parse_args. rakit's validator treats false as non-empty (Required::check(false) returns !is_null(false) === true), so the model-level default: rules never fired and in: then rejected false. Replaced the false sentinels with empty strings ('') for the relevant fields so rakit recognises them as empty and the defaults take effect.

Payment / Domain / Webhook / Broadcast

Model	Field	Change
payment	`status`	drop `required`, add `default:pending` (helper still overrides with COMPLETED, behaviour unchanged for existing helper callers)
domain	`stage`	drop redundant `required` (already had `default:checking-dns`)
webhook	`integration`	drop `required`, add `default:manual`
broadcast	`type`	drop redundant `required` (already had `default:broadcast_notice`)

What's NOT changed

Membership customer_id, plan_id — genuine FKs, kept required.
Discount code name, code, value — all genuinely essential.
Event — system-internal model; manual creation is rare and the defaults would need extra care. Skipped to avoid surprising the event ingest pipeline.
Payment customer_id, subtotal, total — genuine FK + the payment amount; kept required.
Domain blog_id, domain — must point to a site, must be unique; kept required.
Webhook name, webhook_url, event — all essential.
Broadcast title, content — all essential.
Product slug — kept required because it's used as a unique URL key. Could be auto-derived from name later but that's a separate change.

Verification

After this change, every multisite-ultimate/*-create-item ability accepts a minimal payload:

customer:      ["user_id"]
product:       ["slug"]                       (was: slug, currency, pricing_type, type)
payment:       ["customer_id","subtotal","total"]
domain:        ["domain","blog_id"]
webhook:       ["name","webhook_url","event"]
broadcast:     ["title","content"]
membership:    ["customer_id","plan_id"]      (unchanged, both genuine FKs)
discount-code: ["name","code","value"]        (unchanged, all essential)
site:          ["title","name","path","type"] (was: site_id, description,
                                              customer_id, membership_id, ...)

Smoke tests via wp_get_ability(...)->execute(...) confirmed each entity creates successfully with only the minimal payload, and the defaults populate the omitted fields with the documented values.

End-to-end test against an LLM agent with the same prompt that previously failed ("Create a new subsite all about space and astronomy") now succeeds in 2 iterations on the model side, calling multisite-ultimate/site-create-item directly with only title, name, path, type and producing a routable subsite at the correct subdomain.

Test plan

PHPUnit suite passes
PHPStan clean (verified locally during commit)
Manual: wp_get_ability('multisite-ultimate/site-create-item')->execute(['title'=>'X','name'=>'x','path'=>'x','type'=>'default']) succeeds on a subdomain install and produces a routable site at x.<network>
Manual: wp_get_ability('multisite-ultimate/site-create-item')->execute(['title'=>'X','name'=>'x','path'=>'/x/','type'=>'default']) succeeds on a subdirectory install and produces a routable site at <network>/x/
Manual: existing form-based creation flow in the network admin still works (none of these helpers are called with false sentinels by the form layer; HTML forms post empty strings)
Manual: customer/product/payment/domain/webhook/broadcast minimal-payload create via wp eval round-trip

Summary by CodeRabbit

Bug Fixes
- Fixed validation behavior across multiple models (Product, Site, Customer, Domain, Payment, Broadcast, Webhook) to properly apply default values when fields are omitted, reducing required inputs during creation and updates.
Improvements
- Enhanced site creation logic to better normalize domain and path handling, with improved support for multisite subdomain configurations.

📝 Walkthrough

Walkthrough

The pull request adjusts validation rules and default value handling across eight model classes and two functions. Changes primarily remove required constraints while adding or refining default: rules to make fields optional. Additionally, wu_create_product() shifts default sentinels from false to empty strings for text properties to ensure model defaults apply, and wu_create_site() adds domain/path normalization logic for multisite subdomain handling.

Changes

Cohort / File(s)	Summary
Function defaults and argument normalization `inc/functions/product.php`, `inc/functions/site.php`	`wu_create_product()` changes default sentinels from `false` to `''` for text/scalar fields to permit model-level defaults to fire. `wu_create_site()` adds mode-aware domain/path normalization logic, deriving network domain and converting paths to subdomain prefixes on subdomain multisite installs.
Validation rule relaxation - Product and Payment `inc/models/class-product.php`, `inc/models/class-payment.php`	`Product` removes `required` from `currency` and `pricing_type`, adds default `free` for pricing type. `Payment` removes `required` from `status` and applies default `pending`.
Validation rule relaxation - Customer and Site `inc/models/class-customer.php`, `inc/models/class-site.php`	`Customer` makes `email_verification` and `type` optional with defaults (`none` and `customer` respectively). `Site` makes `site_id`, `description`, `customer_id`, and `membership_id` optional with appropriate defaults; updates docblocks for domain/path semantics.
Validation rule relaxation - Broadcast, Domain, and Webhook `inc/models/class-broadcast.php`, `inc/models/class-domain.php`, `inc/models/class-webhook.php`	`Broadcast` removes `required` from `type`. `Domain` removes `required` from `stage`. `Webhook` removes `required` from `integration` and applies default `manual`.

⚠️ Potential issue | 🟠 Major

Defaulting site_id to 1 can create sites in the wrong network.

Line 336 hard-defaults to 1, and save() later uses $this->get_site_id() ?: get_current_network_id(), so omitted site_id never falls back to the current network. On multi-network installs, this can route creations to network 1 unintentionally.

Summary

The MCP *-create-item abilities (registered via trait-mcp-abilities.php) read each model's validation_rules() to build their JSON Schema and mark fields as required. Several models flagged fields that are either WaaS-specific extras (customer_id, membership_id on a default WP subsite), the only valid value (type on customer), or already had sensible model-level defaults that made required redundant.
Result: AI callers (and any other programmatic caller of wu_create_*) had to supply ~6 fields to create a vanilla WP subsite when only 4 are genuinely needed, and similar for the other entities. Weak LLMs would either guess wrong values or fall back to db-query / run-php hacks.
This PR removes 11 spurious required flags across 7 models, adds explicit default: rules where one was missing, fixes a related bug in wu_create_product that prevented model-level defaults from firing, and fixes a subdomain-mode routing bug in wu_create_site.
Companion PR in Ultimate-Multisite/gratis-ai-agent#807 adds the auto-discovery layer that surfaces these abilities to the agent in the first place — together they make it possible for an LLM agent to create a Multisite Ultimate subsite from a one-line prompt.

Why

When an LLM agent sees the create-item schema for these models, every required field forces it to either guess a value or call a fetcher ability first. For the genuine fields (title, customer_id on a payment) that's fine — for spurious ones it's pure friction. The same applies to humans writing scripts against wu_create_*.
The site model in particular: a vanilla WordPress subsite (type: default) doesn't need a customer or membership — those are WaaS-specific concepts. Forcing them required the agent to walk a four-call workflow (list customers → list products → create membership → create site) just to reach a regular blog. With this PR a single site-create-item call with {title, name, path, type} suffices.

Field	Was	Now
`site_id`	`required\|integer`	`integer\|default:1`
`description`	`required\|min:2`	`default:`
`customer_id`	`required\|integer\|exists:...`	`integer\|default:\|exists:...`
`membership_id`	`required\|integer\|exists:...`	`integer\|default:\|exists:...`
`title`, `name`, `path`, `type` remain required (genuine WordPress minimum). The `exists:` foreign-key check still fires when a value is supplied so customer-owned sites still validate correctly.

Subdomain mode (`inc/functions/site.php`)

wu_create_site() now detects subdomain multisite installs and auto-converts a supplied path slug into the correct subdomain ({slug}.{network-domain}) when no explicit domain was given. The existing wu_get_site_domain_and_path() helper does this conversion but wu_create_site() never used it — programmatic callers passing path: "blog" on a subdomain install ended up with an unroutable site row at <network>/blog. Subdomain/subdirectory mixing still works because callers that pass an explicit non-root domain are respected as-is.
set_domain() and set_path() doc comments rewritten to make the mode-aware behaviour explicit so any tool that surfaces field descriptions to an LLM (or any human reader) gets the right guidance.

Customer (`inc/models/class-customer.php`)

Field	Was	Now
`email_verification`	`required\|in:none,pending,verified`	`in:...\|default:none`
`type`	`required\|in:customer`	`in:customer\|default:customer`
`type` only ever accepts one value, so requiring callers to specify it is pure friction.

Product (`inc/models/class-product.php` + `inc/functions/product.php`)

Field	Was	Now
`currency`	`required\|default:{site_currency}`	`default:{site_currency}`
`pricing_type`	`required\|in:free,paid,...`	`in:...\|default:free`
`type`	`required\|default:plan\|in:...`	`default:plan\|in:...`
Bonus fix in `wu_create_product()`: the helper pre-filled missing fields with `false` sentinels via `wp_parse_args`. rakit's validator treats `false` as non-empty (`Required::check(false)` returns `!is_null(false) === true`), so the model-level `default:` rules never fired and `in:` then rejected `false`. Replaced the `false` sentinels with empty strings (`''`) for the relevant fields so rakit recognises them as empty and the defaults take effect.

Payment / Domain / Webhook / Broadcast

Model	Field	Change
payment	`status`	drop `required`, add `default:pending` (helper still overrides with COMPLETED, behaviour unchanged for existing helper callers)
domain	`stage`	drop redundant `required` (already had `default:checking-dns`)
webhook	`integration`	drop `required`, add `default:manual`
broadcast	`type`	drop redundant `required` (already had `default:broadcast_notice`)

What's NOT changed

Membership customer_id, plan_id — genuine FKs, kept required.
Discount code name, code, value — all genuinely essential.
Event — system-internal model; manual creation is rare and the defaults would need extra care. Skipped to avoid surprising the event ingest pipeline.
Payment customer_id, subtotal, total — genuine FK + the payment amount; kept required.
Domain blog_id, domain — must point to a site, must be unique; kept required.
Webhook name, webhook_url, event — all essential.
Broadcast title, content — all essential.
Product slug — kept required because it's used as a unique URL key. Could be auto-derived from name later but that's a separate change.

Verification

After this change, every multisite-ultimate/*-create-item ability accepts a minimal payload:

customer:      ["user_id"]
product:       ["slug"]                       (was: slug, currency, pricing_type, type)
payment:       ["customer_id","subtotal","total"]
domain:        ["domain","blog_id"]
webhook:       ["name","webhook_url","event"]
broadcast:     ["title","content"]
membership:    ["customer_id","plan_id"]      (unchanged, both genuine FKs)
discount-code: ["name","code","value"]        (unchanged, all essential)
site:          ["title","name","path","type"] (was: site_id, description,
                                              customer_id, membership_id, ...)

Smoke tests via wp_get_ability(...)->execute(...) confirmed each entity creates successfully with only the minimal payload, and the defaults populate the omitted fields with the documented values.
End-to-end test against an LLM agent with the same prompt that previously failed ("Create a new subsite all about space and astronomy") now succeeds in 2 iterations on the model side, calling multisite-ultimate/site-create-item directly with only title, name, path, type and producing a routable subsite at the correct subdomain.

Test plan

PHPUnit suite passes
PHPStan clean (verified locally during commit)
Manual: wp_get_ability('multisite-ultimate/site-create-item')->execute(['title'=>'X','name'=>'x','path'=>'x','type'=>'default']) succeeds on a subdomain install and produces a routable site at x.<network>
Manual: wp_get_ability('multisite-ultimate/site-create-item')->execute(['title'=>'X','name'=>'x','path'=>'/x/','type'=>'default']) succeeds on a subdirectory install and produces a routable site at <network>/x/
Manual: existing form-based creation flow in the network admin still works (none of these helpers are called with false sentinels by the form layer; HTML forms post empty strings)
Manual: customer/product/payment/domain/webhook/broadcast minimal-payload create via wp eval round-trip
