Lunar Pr Review

Lunar PR Review

Overview

Lunar is a Laravel-based headless commerce package distributed as a monorepo (packages/core, packages/admin, plus payment/search adapters). PRs target the 1.x branch. This skill runs a deterministic review pass tuned to the patterns that actually exist in this codebase, surfaces findings as path:line — issue — fix, and groups them by severity. It does not make changes.

When to Activate

• Slash command /lunar:pr-review (with optional base branch arg).
• Natural-language requests: "review this PR", "review the branch", "review the diff", "check my changes before I push".
• Skip if the user wants a brand-new implementation — this skill is read-only review.

Scope

• In scope: changed files between HEAD and origin/1.x (or a user-supplied base).
• Out of scope: unchanged files, generated docs (packages/*/resources/views/vendor), vendor/, lock files beyond noting they changed.

Workflow

1. Determine base branch. Default 1.x. If the user passed an arg (e.g. /lunar:pr-review main), use that. Run git fetch origin <base> --quiet.
2. Collect the diff.
   • Files: git diff --name-status origin/<base>...HEAD
   • Commits: git log --oneline origin/<base>..HEAD
   • If empty, report "no changes vs <base>" and stop.
3. Classify each changed file into buckets: migrations, translations, models, filament, observers/events, tests, composer, factories, other.
4. Run category checks (see below). Build a findings list with severity, path, line (when known), issue, suggested fix.
5. Render report grouped as Blockers → Should fix → Nits. End with a "Run before merge" footer.

Categories

Each check below states what to look for and the severity to assign. See references/checklist.md for full rationale and good/bad examples.

Translations (Blocker on missing, Should-fix on stale)

Run php .claude/skills/lunar-pr-review/scripts/missing-translations.php from the repo root. The script flattens nested array keys to dot notation and diffs en/ against ar bg de es fa fr hr hu mn nl pl pt_BR ro tr vi for every packages/*/resources/lang/<locale>/<file>.php.

• [missing] … → key exists in en/ but not in target locale → Blocker if the PR added the key; Should-fix if pre-existing.
• [stale] … → key in target locale no longer in en/ → Should-fix.
• [missing-file] … → whole file absent in target locale → Should-fix.

Also scan added strings in PHP/Blade for hardcoded user-facing English that should be __('lunarpanel::…').

Tests (Pest) — Should-fix

For each newly added class under packages/*/src/:

• Models, services, actions, observers, jobs, and events should have a matching Pest test under tests/{core,admin,opayo,paypal,shipping,stripe,search}/.
• New Eloquent models additionally require a factory under packages/*/database/factories/.
• Use php artisan make:test --pest <Name>Test (do not write to tests/Feature/ paths directly).

Migrations — Blocker

For each migration in packages/*/database/migrations/:

• Must extend Lunar\Base\Migration (not Illuminate\Database\Migrations\Migration directly).
• Must use $this->prefix when referencing table names (Schema::table($this->prefix.'orders', …)).
• Must implement down() symmetrically — every Schema::create / column-add in up() is reversed.
• Foreign keys use foreignId(...)->constrained() with explicit onDelete/onUpdate where the parent model uses soft deletes.
• Destructive column drops on existing tables require a justification comment or a paired data migration.
• File name follows YYYY_MM_DD_HHMMSS_<verb>_<thing>.php.

Filament resources & admin — Should-fix

For files under packages/admin/src/Filament/Resources/:

• protected static ?string $model = …Contract::class; — must reference an interface from Lunar\Models\Contracts\*, not a concrete model.
• Labels: getLabel, getPluralLabel, getNavigationGroup, form/column labels must come from __('lunarpanel::…'); flag any hardcoded English strings.
• New resources set protected static ?string $permission.
• Navigation icons resolved via FilamentIcon::resolve('lunar::…').

Model contracts (type-hinting) — Blocker

Eloquent models in packages/*/src/Models/ are bound to interfaces in Lunar\Models\Contracts\* via the model manifest, so consumers can swap in their own subclass. Code that type-hints the concrete model defeats that extension point.

Anywhere outside the model class itself and its factory/seeder, type hints, return types, property types, and PHPDoc references must use the contract, not the concrete model:

• Method parameters & return types: public function handle(CartContract $cart, Closure $next): CartContract.
• Promoted/declared properties: protected ?OrderContract $order = null;.
• PHPDoc: @param Closure(OrderContract): mixed $next, @return Collection<int, ProductContract>.
• DI / container resolution: app(CartContract::class), not app(Cart::class) or new Cart.

Exemptions (concrete class is correct here):

• The model class itself, its relations, scopes, and casts.
• Factories, seeders, and migrations.
• Tests creating fixtures (Product::factory()->create()).
• instanceof checks against the concrete class only when there is a documented reason (otherwise prefer the contract).

Flag as Blocker in new/changed code: use Lunar\Models\Foo; followed by a type hint Foo $foo in a service, action, manager, pipeline, observer, listener, event, or job. Suggest the fix as use Lunar\Models\Contracts\Foo as FooContract; and rename the hint to FooContract.

PHP conventions — Should-fix / Nit

Per repo CLAUDE.md:

• Constructor property promotion required for public constructor params; flag empty zero-param __construct().
• Explicit return types and typed parameters on every method.
• Curly braces around every control-structure body, even one-liners.
• Prefer PHPDoc blocks over inline comments; array shape types in PHPDoc.
• Never call env() outside config/.
• Enum case keys in TitleCase.

Static analysis & style — Nit (reminder)

• If changed files fall inside paths excluded by phpstan.neon.dist, note that PHPStan will not catch issues there.
• Remind the user to run vendor/bin/pint --dirty --format agent before pushing.

Composer / dependencies — Blocker (requires user confirmation)

Any diff in composer.json or any packages/*/composer.json:

• Flag added/removed/upgraded dependencies as a Blocker that needs explicit user sign-off per CLAUDE.md.
• Note PHP version, Laravel version, or Filament version bumps separately — they affect downstream consumers.

Channel scoping — Blocker

Lunar is multi-channel. Models using Lunar\Base\Traits\HasChannels (Product, Collection, Discount, …) expose scopeChannel() for filtering.

• New queries on these models in admin lists, storefront-facing endpoints, or scheduled jobs should call ->channel($channel) (or be explicitly justified as cross-channel).
• New columns/relations on a channelled model that drive visibility need the channel scope wired in, not just the column added.

Reuse existing scopes & traits — Should-fix

Before reviewing any new Eloquent query, check whether the related trait/model already exposes a scope for the same condition. Hand-rolled ->where(...)->orWhere(...) chains that duplicate a trait scope are a Should-fix.

• Lunar\Base\Traits\HasCustomerGroups exposes a scope for customer-group eligibility (enabled/visible/starts_at/ends_at windowing). New ->customerGroups()->where('enabled', true)… chains in resources, widgets, validators, or pipelines should use that scope.
• Lunar\Base\Traits\HasChannels — see Channel scoping above; use ->channel(...), not ->channels()->where('enabled', true)….
• Lunar\Base\Traits\HasUrls — use the default() / active scope rather than re-checking columns inline.
• Status enums on Product, Order, etc. — prefer ->whereIn('status', SomeStatus::active()) or the existing helper over string-literal comparisons.

When flagging, name the specific trait/scope the author should use, not just "use a scope". If the scope doesn't exist yet but the same chain is repeated 2+ times in the diff, suggest adding it to the trait.

Control-flow simplification — Nit (Should-fix when stacked)

Lunar's Filament resources and validators have accumulated long ladders of if ($x) { return true; } if ($y) { return true; } inside closures (notably Shout::make(...)->hidden(fn ...)). Reviewers consistently push back on these — flag them.

• Multiple sequential if (cond) { return $literal; } returning the same literal collapse into one if (a || b || c) { return $literal; } or a single boolean expression on the return.
• A trailing if (! $x) { return true; } return (bool) $x; is just return ! $x; (or the equivalent expression).
• Guard clauses are fine and preferred over nested if/else, but each one should branch to a different outcome — back-to-back guards returning the same value are noise.
• Closures that grow past ~5 statements doing query composition should be extracted to a named private method or, better, an Eloquent scope (see above).

Treat a single instance as a Nit; flag as Should-fix when the same closure stacks 3+ early returns or when the pattern repeats across sibling components in the same file.

Money & price handling — Blocker

Money in Lunar lives in Lunar\DataTypes\Price (integer minor units + Currency) and the Lunar\Base\Casts\Price cast.

• Flag new monetary columns as decimal/float — they should be unsignedInteger/bigInteger and cast through Price.
• Flag float arithmetic on money: * 0.01, (float), round() on raw totals, +/-/* between mixed-currency Price instances.
• New tax/discount/shipping totals must go through the existing pipeline calculation, not be set directly on the model.

Search indexing (Scout/Meilisearch) — Should-fix

Search documents are built by packages/core/src/Search/*Indexer.php (ProductIndexer, CollectionIndexer, CustomerIndexer, OrderIndexer, ProductOptionIndexer).

• Adding a queryable/filterable attribute to an indexed model? The corresponding *Indexer must include it in the document.
• Removing an attribute? Note that indexed documents are now stale and need a re-index step (php artisan scout:import "<Model>").
• New filterable/sortable attributes likely need the Meilisearch filterableAttributes / sortableAttributes config updated.

Pipelines — Blocker on calculation paths

Cart, cart line, cart prune, and order pipelines live under packages/core/src/Pipelines/. Lunar resolves them from config so consumers can extend or replace them.

• Adding a new field to CartLine/Cart/Order that affects price, tax, shipping, or eligibility means adding (or extending) the relevant pipeline stage — not just persisting the field.
• New pipeline stages must be registered in config/lunar/cart.php / config/lunar/orders.php and have a Pest test.
• Reordering existing stages is a behavior change — flag loudly.

Event payload stability — Blocker

Event classes under packages/*/src/Events/ and packages/*/src/Base/Events/ are public API on 1.x. Listeners depend on the constructor signature and public properties.

• Renaming/removing/retyping constructor params or public properties on an existing event is breaking.
• Adding new optional params at the end of a constructor is acceptable; new public properties are acceptable.
• New events that should be dispatched from observers/actions but aren't — flag as Should-fix.

Public API surface — Blocker

1.x is a stable line. The following count as breaking changes and must be flagged loudly:

• Any change in packages/*/src/Models/Contracts/ (added/removed/renamed methods, changed signatures).
• Public method signature changes on classes that implement a Contracts/* interface.
• Removed or renamed events under packages/*/src/Base/Events/ or packages/*/src/Events/.
• Removed config keys in packages/*/config/*.php.
• Migrations that rename existing tables/columns without a backwards-compatible accessor.

Output Format

# Lunar PR Review — <branch> vs <base>

<N commits, M files changed>

## Blockers (must fix before merge)
- `path/to/file.php:L42` — <issue> — <suggested fix>
- …

## Should fix
- `path/to/file.php:L11` — <issue> — <suggested fix>
- …

## Nits
- `path/to/file.php` — <issue>

- `vendor/bin/phpstan analyse`

If there are no findings in a section, omit it. If there are zero findings overall, output a single line: No findings vs <base> across <N> files.

Do / Don't

Do:

• Run the translations script — do not eyeball 16 locales.
• Quote line numbers from git diff --unified=0 when available so the user can jump to them.
• Recommend php artisan make:* commands for any missing scaffolding rather than describing hand-rolled code.

Don't:

• Don't edit any files.
• Don't push, force-push, rebase, or reset.
• Don't run composer update, composer require, npm install, or migrations.
• Don't claim a file is fine without actually reading the changed hunks.
• Don't duplicate findings — each path:line appears once at its highest severity.
