Defuse links in X posts to avoid the link-post fee (#308 )

X bills a post containing a URL at a much higher rate than a plain post, and
its algorithm demotes link posts. The X version of a post now rewrites every
URL non-clickable (https://example.com/post becomes example(.)com/post):
scheme and www. dropped, every dot of the host replaced with (.).

Leaving a single dot intact would still leave a resolvable domain for X to
detect, so all of them are broken. A scheme or www. proves a token is a URL on
its own; a bare host only counts when its last label is a delegated TLD, which
is the one thing telling acme.com apart from Node.js. That check runs against
App\Support\LinkTlds, generated from the whole IANA root zone in every form a
TLD can appear in a post -- ASCII, punycode and the Unicode it decodes to --
because whatever X links is what X bills, so a hand-picked subset would leave
us paying for its gaps. If the regex engine bails out on pathological input the
original content is returned instead of crashing the publisher.

The transform lives in the Platform::X arm of ContentSanitizer, so it reaches
publishing and the app/API/MCP previews from one place and cannot touch any
other network. Off by default; opt in with X_DEFUSE_LINKS.

The editor counts characters and renders its preview client-side and cannot ask
the server on every keystroke, so the rewrite is mirrored in TypeScript. PHP
stays the source of truth: a parity test fails if the two TLD sets drift, and a
browser test drives the real editor so the mirror is covered rather than
assumed. Without it the composer promised text the network never receives.

Character limits now measure the text a reader will see: sanitized, then with
markup resolved away. Measuring the raw draft blocked saving posts that publish
fine and let through posts the network rejects, and counted the editor's HTML
toward the limit. Measuring the sanitized form alone would have counted
Telegram's escaped entities, rejecting messages Telegram accepts.

Empty content is handled once inside the sanitizer instead of by a guard
repeated at every call site.

Laravel Boost Guidelines

The Laravel Boost guidelines are specifically curated by Laravel maintainers for this application. These guidelines should be followed closely to ensure the best experience when building Laravel applications.

Foundational Context

This application is a Laravel application running on PHP 8.5. You are an expert with the Laravel ecosystem. Always use the APIs that match the installed major version of each package — do not assume a version.

Before relying on a package's API, confirm its installed version:

PHP packages: run composer show --direct to list direct dependencies with versions, or composer show <vendor/package> for a single package.
JS packages: check package.json for the installed versions.

Skills Activation

This project has domain-specific skills available in **/skills/**. You MUST activate the relevant skill whenever you work in that domain—don't wait until you're stuck.

Conventions

You must follow all existing code conventions used in this application. When creating or editing a file, check sibling files for the correct structure, approach, and naming.
Use descriptive names for variables and methods. For example, isRegisteredForDiscounts, not discount().
Check for existing components to reuse before writing a new one.

Verification Scripts

Do not create verification scripts or tinker when tests cover that functionality and prove they work. Unit and feature tests are more important.

Application Structure & Architecture

Stick to existing directory structure; don't create new base folders without approval.
Do not change the application's dependencies without approval.

Frontend Bundling

If the user doesn't see a frontend change reflected in the UI, it could mean they need to run npm run build, npm run dev, or composer run dev. Ask them.

Documentation Files

You must only create documentation files if explicitly requested by the user.

Replies

Be concise in your explanations - focus on what's important rather than explaining obvious details.

=== boost rules ===

Laravel Boost

Tools

Laravel Boost is an MCP server with tools designed specifically for this application. Prefer Boost tools over manual alternatives like shell commands or file reads.
Use database-query to run read-only queries against the database instead of writing raw SQL in tinker.
Use database-schema to inspect table structure before writing migrations or models.
Use get-absolute-url to resolve the correct scheme, domain, and port for project URLs. Always use this before sharing a URL with the user.
Use browser-logs to read browser logs, errors, and exceptions. Only recent logs are useful, ignore old entries.

Searching Documentation (IMPORTANT)

Always use search-docs before making code changes. Do not skip this step. It returns version-specific docs based on installed packages automatically.
Pass a packages array to scope results when you know which packages are relevant.
Use multiple broad, topic-based queries: ['rate limiting', 'routing rate limiting', 'routing']. Expect the most relevant results first.
Do not add package names to queries because package info is already shared. Use test resource table, not filament 4 test resource table.

Search Syntax

Use words for auto-stemmed AND logic: rate limit matches both "rate" AND "limit".
Use "quoted phrases" for exact position matching: "infinite scroll" requires adjacent words in order.
Combine words and phrases for mixed queries: middleware "rate limit".
Use multiple queries for OR logic: queries=["authentication", "middleware"].

Project Rules

This project keeps committed, area-grouped rules in .ai/rules (settled decisions, non-obvious traps, standing constraints). Framework and package guidelines that only apply to specific paths (testing, frontend, components) also live there, under .ai/rules/boost — this is not just recorded decisions, it is load-bearing guidance you have not seen inline. Before you enter plan mode or create/edit any file, you MUST first: open @.ai/rules/index.md (it maps file globs to rule files), read every rule file whose globs cover the path(s) in scope, and run grep -rin 'keyword' .ai/rules to catch what a path match alone misses. Do not write code until you have read and are following every matching rule.
Record durable rules with record-rule so the next agent or teammate inherits them instead of working them out again. Pass a glob (e.g. app/Http/Controllers/**), a short title, and a few-line note. Always use record-rule, never your native memory or notes tool — native memory is personal and session-scoped; only .ai/rules is shared with the team and persists in the repo.

Artisan

Run Artisan commands directly via the command line (e.g., php artisan route:list). Use php artisan list to discover available commands and php artisan [command] --help to check parameters.
Inspect routes with php artisan route:list. Filter with: --method=GET, --name=users, --path=api, --except-vendor, --only-vendor.
Read configuration values using dot notation: php artisan config:show app.name, php artisan config:show database.default. Or read config files directly from the config/ directory.

Tinker

Execute PHP in app context for debugging and testing code. Do not create models without user approval, prefer tests with factories instead. Prefer existing Artisan commands over custom tinker code.
Always use single quotes to prevent shell expansion: php artisan tinker --execute 'Your::code();'
- Double quotes for PHP strings inside: php artisan tinker --execute 'User::where("active", true)->count();'

=== php rules ===

PHP

Always use curly braces for control structures, even for single-line bodies.
Use PHP 8 constructor property promotion: public function __construct(public GitHub $github) { }. Do not leave empty zero-parameter __construct() methods unless the constructor is private.
Use explicit return type declarations and type hints for all method parameters: function isAccessible(User $user, ?string $path = null): bool
Use TitleCase for Enum keys: FavoritePerson, BestLake, Monthly.
Prefer PHPDoc blocks over inline comments. Only add inline comments for exceptionally complex logic.
Use array shape type definitions in PHPDoc blocks.

=== deployments rules ===

Deployment

Laravel can be deployed using Laravel Cloud, which is the fastest way to deploy and scale production Laravel applications.

=== herd rules ===

Laravel Herd

The application is served by Laravel Herd at https?://[kebab-case-project-dir].test. Use the get-absolute-url tool to generate valid URLs. Never run commands to serve the site. It is always available.
Use the herd CLI to manage services, PHP versions, and sites (e.g. herd sites, herd services:start <service>, herd php:list). Run herd list to discover all available commands.

=== tests rules ===

Test Enforcement

Every change must be programmatically tested. Write a new test or update an existing test, then run the affected tests to make sure they pass.
Run the minimum number of tests needed to ensure code quality and speed. Use php artisan test --compact with a specific filename or filter.

=== inertia-laravel/core rules ===

Inertia

Inertia creates fully client-side rendered SPAs without modern SPA complexity, leveraging existing server-side patterns.
Components live in resources/js/pages (unless specified in vite.config.js). Use Inertia::render() for server-side routing instead of Blade views.
ALWAYS use search-docs tool for version-specific Inertia documentation and updated code examples.
IMPORTANT: Activate inertia-vue-development when working with Inertia Vue client-side patterns.

Inertia v3

Use all Inertia features from v1, v2, and v3. Check the documentation before making changes to ensure the correct approach.
New v3 features: standalone HTTP requests (useHttp hook), optimistic updates with automatic rollback, layout props (useLayoutProps hook), instant visits, simplified SSR via @inertiajs/vite plugin, custom exception handling for error pages.
Carried over from v2: deferred props, infinite scroll, merging props, polling, prefetching, once props, flash data.
When using deferred props, add an empty state with a pulsing or animated skeleton.
Axios has been removed. Use the built-in XHR client with interceptors, or install Axios separately if needed.
Inertia::lazy() / LazyProp has been removed. Use Inertia::optional() instead.
Prop types (Inertia::optional(), Inertia::defer(), Inertia::merge()) work inside nested arrays with dot-notation paths.
SSR works automatically in Vite dev mode with @inertiajs/vite - no separate Node.js server needed during development.
Event renames: invalid is now httpException, exception is now networkError.
router.cancel() replaced by router.cancelAll().
The future configuration namespace has been removed - all v2 future options are now always enabled.

=== laravel/core rules ===

Do Things the Laravel Way

Use php artisan make: commands to create new files (i.e. migrations, controllers, models, etc.). You can list available Artisan commands using php artisan list and check their parameters with php artisan [command] --help.
If you're creating a generic PHP class, use php artisan make:class.
Pass --no-interaction to all Artisan commands to ensure they work without user input. You should also pass the correct --options to ensure correct behavior.

Model Creation

When creating new models, create useful factories and seeders for them too. Ask the user if they need any other things, using php artisan make:model --help to check the available options.

APIs & Eloquent Resources

For APIs, default to using Eloquent API Resources and API versioning unless existing API routes do not, then you should follow existing application convention.

URL Generation

When generating links to other pages, prefer named routes and the route() function.

Testing

When creating models for tests, use the factories for the models. Check if the factory has custom states that can be used before manually setting up the model.
Faker: Use methods such as $this->faker->word() or fake()->randomDigit(). Follow existing conventions whether to use $this->faker or fake().
When creating tests, make use of php artisan make:test [options] {name} to create a feature test, and pass --unit to create a unit test. Most tests should be feature tests.

Vite Error

If you receive an "Illuminate\Foundation\ViteException: Unable to locate file in Vite manifest" error, you can run npm run build or ask the user to run npm run dev or composer run dev.

=== wayfinder/core rules ===

Laravel Wayfinder

Use Wayfinder to generate TypeScript functions for Laravel routes. Import from @/actions/ (controllers) or @/routes/ (named routes).

=== pint/core rules ===

Laravel Pint Code Formatter

If you have modified any PHP files, you must run vendor/bin/pint --dirty --format agent before finalizing changes to ensure your code matches the project's expected style.
Do not run vendor/bin/pint --test --format agent, simply run vendor/bin/pint --format agent to fix any formatting issues.

=== pest/core rules ===

Pest

This project uses Pest for testing. Create tests: php artisan make:test --pest {name}.
The {name} argument should not include the test suite directory. Use php artisan make:test --pest SomeFeatureTest instead of php artisan make:test --pest Feature/SomeFeatureTest.
Run tests: php artisan test --compact or filter: php artisan test --compact --filter=testName.
Do NOT delete tests without approval.

=== inertia-vue/core rules ===

Inertia + Vue

Vue components must have a single root element.

IMPORTANT: Activate inertia-vue-development when working with Inertia Vue client-side patterns.

Project-Specific Rules

Stripe Checkout (env knobs)

Checkout options are configured only via env — do not hardcode trial/coupon/promo behavior in controllers. All of it goes through App\Support\Billing\ConfigureSubscriptionCheckout (called from StartSubscriptionCheckout).

Env	Config	Default	Effect
`REQUIRE_CARD_FOR_TRIAL`	`trypost.billing.require_card_for_trial`	`true`	`true`: app access only after Stripe Checkout (no generic signup trial). `false`: generic `accounts.trial_ends_at` trial without a card
`CASHIER_TRIAL_DAYS`	`cashier.trial_days`	`8`	Card-required Checkout: `trialDays(N)` for first-time subscribers when no first-month coupon is applied (`0` = off). Re-subscribers skip trial. No-card mode: length of the generic signup trial
`STRIPE_FIRST_MONTH_COUPON_ID`	`cashier.first_month_coupon_id`	empty	Optional. When set for a qualifying first-time single-workspace checkout, applies `withCoupon` and skips trial. Empty = trial mode
`CASHIER_ALLOW_PROMOTION_CODES`	`cashier.allow_promotion_codes`	`false`	When `true` and no coupon is applied, show the Checkout promo-code field

Standing constraints:

Stripe rejects discounts (coupon) and allow_promotion_codes on the same session — if both would apply, ConfigureSubscriptionCheckout must throw (fail loud). Never “prefer one silently.” Envs may both be set when the account does not qualify for the coupon (no throw).
A set first-month coupon wins over trial (trialDays is skipped for that checkout).
Empty coupon + card required + first-time must use trialDays — do not reintroduce a required-coupon throw.
Coupon qualification stays: card required, exactly one workspace, no prior real subscription (incomplete / incomplete_expired still qualify).
Prefer documenting durable billing decisions here (and in CLAUDE.md) — do not create a .ai/ rules folder for this project.

One connected identity per social network per workspace is the Cloud default. This is not tied to SELF_HOSTED — Cloud cannot flip that flag, but it can flip this one.

Env	Config	Default	Effect
`ALLOW_MULTIPLE_SOCIAL_ACCOUNTS`	`trypost.allow_multiple_social_accounts`	`false` (falls back to `SELF_HOSTED` when unset)	`true`: a workspace may connect more than one account of the same network (two LinkedIns, two Instagrams, …). `false`: one per network (LinkedIn profile + page count as one; Instagram standalone + Instagram-via-Facebook count as one). Reconnecting the same `platform` + `platform_user_id` still updates the existing row. Shared to Inertia as `allowMultipleSocialAccounts`.

Self-hosted compose / .env.example set this true. When the env is unset, the config falls back to SELF_HOSTED so existing self-hosted installs keep multiple accounts. Do not use selfHosted for the occupancy check (observer, Telegram connect, NetworkConnectGrid).

Database engines (PostgreSQL + MySQL)

TryPost runs on both PostgreSQL and MySQL. Cloud runs PostgreSQL; a self-hosted install may pick either. Every query, migration, and test must work on both — the suite is expected to be green on each.

What the app supports is the intersection of the two engines, never the superset of one. When they differ, take the narrower behaviour — a feature that only holds on PostgreSQL is a feature TryPost does not have.
Never use an engine-specific operator or function. Search uses whereLike() (Laravel handles the case-insensitive form per driver), never ilike or a raw LOWER(...) comparison.
Traps that only surface on MySQL:
- JSON object key order is not preserved. MySQL reorders object keys on storage (by length, then lexicographically); PostgreSQL keeps insertion order. Assert JSON read back from the database with toEqual (recursive, order-independent), never toBe/assertSame. Array element order is preserved on both.
- $table->timestamp() tops out at 2038-01-19. PostgreSQL has no such limit, so 2038-01-19 is the app's ceiling: nothing written to a timestamp() column may go past it — scheduled posts, expiry sentinels and test fixtures alike. 2037-12-31 reads as "far future" and works on both. Do not widen a column to escape the limit without a deliberate decision; it changes what self-hosted MySQL installs can store.
- Raw query-builder reads carry no Eloquent cast, so the driver's native shape leaks through: DB::table(...)->value('some_bool') is true on PostgreSQL and 1 on MySQL. Read through the model, or use assertDatabaseHas.
- Identifier quoting differs — PostgreSQL emits "post_platforms", MySQL emits backticks. Never match logged SQL (DB::listen) against a quoted identifier.
- MySQL refuses to drop the only index backing a foreign key (SQLSTATE 1553). A migration down() that drops a unique whose leftmost prefix is an FK column must create a standalone index for that column first.
- DDL implicitly commits, which defeats RefreshDatabase's rollback: schema changes made inside a test leak into the tests that follow. Keep them idempotent.

Always consult the official docs below before implementing or changing OAuth, publishing, deletion, rate-limit, or any other platform-specific behavior — never guess endpoints, scopes, rate limits, or capabilities from memory. APIs shift over time; a behavior confirmed in a past session may no longer hold. One entry per social network we integrate with:

Facebook / Instagram / Threads (Meta): all three share the Graph API error format (error.code, error.type).
- General error handling / codes 1, 2, 4, 17, 190: https://developers.facebook.com/docs/graph-api/guides/error-handling/
- Rate limiting — Platform Rate Limits (app/user tokens, codes 4/17) vs. Business Use Case (BUC) Rate Limits (Page/system-user tokens, codes 80000–80014 — e.g. 80001 Pages API, 80002 Instagram Platform; BUC rejections come back as plain HTTP 400, not 429): https://developers.facebook.com/docs/graph-api/overview/rate-limiting/
- Instagram content-publishing error codes: https://developers.facebook.com/docs/instagram-platform/instagram-graph-api/reference/error-codes/
- Instagram media reference (incl. DELETE): https://developers.facebook.com/docs/instagram-platform/reference/instagram-media/
- Threads API: https://developers.facebook.com/docs/threads — reuses the Graph API error format; no separate Threads-specific error code table exists. Delete posts (needs the separate threads_delete permission, 100 deletes/day/account): https://developers.facebook.com/docs/threads/posts/delete-posts/
- Our App\Services\Social\Meta\GraphError (used by ConnectionVerifier's verify/refresh calls) has the full rationale and code table in its class docblock — check there before changing transient-vs-confirmed-rejection classification.
- Facebook/InstagramFacebook SocialAccounts use a Facebook Page access token (BUC-limited); Instagram (direct login) and Threads use a user access token (Platform Rate Limit-limited). This affects which rate-limit codes apply to which platform.
X (Twitter): API v2 — https://docs.x.com/x-api ; Post management (create/delete) — https://docs.x.com/x-api/posts/manage-tweets/introduction
LinkedIn: Posts API (create/update/delete, member + organization) — https://learn.microsoft.com/en-us/linkedin/marketing/community-management/shares/posts-api (replaces the deprecated ugcPosts API)

X link defusing (env knob)

X bills a post containing a URL at $0.20 vs $0.015 for a plain post (13x), and its algorithm demotes link posts. So on Cloud the ContentSanitizer rewrites every URL in the X version of a post into a non-clickable form — https://example.com/post becomes example(.)com/post.

Env	Config	Default	Effect
`X_DEFUSE_LINKS`	`trypost.platforms.x.defuse_links`	`false`	`true`: URLs in the X version of a post are rewritten non-clickable (scheme and `www.` dropped, every dot of the host replaced with `(.)`). `false`: the X content is published unchanged. Only affects `Platform::X` — every other network keeps the URL intact.
