README

AI agent skills, guidelines, and .gitattributes commands for framework-agnostic Composer package authors. Sibling of sandermuller/package-boost-laravel (Laravel-package flavor); both ride the sandermuller/boost-core sync engine.

Where laravel/boost ships Laravel application guidelines, package-boost-php ships package-author CLI infrastructure (vendor/bin/package-boost-php lean + gitattributes) and skill-authoring tooling for the boost ecosystem. Framework-agnostic, no Laravel dependency. The release-flow content skills (readme, release-notes, upgrading) ship from sandermuller/boost-skills under the release-automation tag.

Which package fits your role?

What you get

Two CLI commands — zero-overlap with laravel/boost. Both target .gitattributes, the file that controls what ends up in the Composer archive.

Two guidelines — pinned context for AI agents working in a package codebase.

Three skills — on-demand workflows for package development.

The readme, release-notes, and upgrading skills moved to sandermuller/boost-skills under the release-automation tag. See UPGRADING for the migration note.

Install

composer require --dev sandermuller/package-boost-php

PHP 8.3+ required. sandermuller/boost-core (the sync engine) and stolt/lean-package-validator (the lean command's checker) come in transitively — do not require sandermuller/boost-core separately, it resolves through this package. One package is the whole install; the auto-sync callback (below) lives under this package's own namespace so your composer.json never names the transitive dependency.

First run

vendor/bin/boost install              # interactive: pick agents, allowlist vendors (writes boost.php)
vendor/bin/boost sync                 # fan out skills + guidelines to selected agents
vendor/bin/package-boost-php gitattributes   # write or refresh the managed .gitattributes block
vendor/bin/package-boost-php lean            # confirm the archive is lean

Generated agent dirs (.claude/, .cursor/, .codex/, etc.) are added to .gitignore automatically; root-level agent files (AGENTS.md, CLAUDE.md) are tracked, not gitignored, per boost-core's tracking model. Edit .ai/ only, then re-run vendor/bin/boost sync.

boost.php config

The canonical example is this repo's own dogfood config (kept at .config/boost.php; root boost.php works too):

<?php declare(strict_types=1);

use SanderMuller\BoostCore\Config\BoostConfig;
use SanderMuller\BoostCore\Enums\Agent;
use SanderMuller\BoostCore\Enums\Tag;

return BoostConfig::configure()
    ->withAgents([
        Agent::CLAUDE_CODE,
        Agent::COPILOT,
        Agent::CODEX,
    ])
    ->withAllowedVendors([
        'sandermuller/boost-core',
        'sandermuller/boost-skills',
        'sandermuller/package-boost-php',
        'stolt/lean-package-validator',
    ])
    ->withTags([
        Tag::Php,
        Tag::Github,
        'release-automation',
        'boost-extension',
    ]);

The absolute minimum to boot is one agent + this package in the allowlist:

return BoostConfig::configure()
    ->withAgents([Agent::CLAUDE_CODE])
    ->withAllowedVendors(['sandermuller/package-boost-php']);

Full configuration reference lives in sandermuller/boost-core's README.

Opt-in tags

withTags(...) filters which skills and guidelines sync. The two opt-ins this package recognises:

• 'release-automation' — pulls this package's release-automation guideline (stays local), and (when sandermuller/boost-skills is allowlisted) the migrated readme / release-notes / upgrading skills from boost-skills.
• 'boost-extension' — pulls skill-authoring + writing-file-emitter for consumers extending the boost ecosystem.

The tag mechanism (withTags(), metadata.boost-tags, subset-rule semantics) is documented in boost-core. Tag vocabulary is illustrative per catalog — boost-skills publishes a worked example; other catalogs may organise differently.

Coexistence

The Laravel-package sibling sandermuller/package-boost-laravel requires this package and layers Laravel-specific skills (Testbench, cross-version-Laravel, CI matrix) and McpJsonEmitter on top. Both packages coexist cleanly with laravel/boost in Laravel-package projects — they handle disjoint concerns: this package is dev-time package authorship; laravel/boost is install-time MCP for downstream Laravel apps.

Auto-sync

To re-sync on every composer install / composer update, wire the callback into your project's composer.json:

"scripts": {
    "post-install-cmd": ["SanderMuller\\PackageBoostPhp\\Scripts\\AutoSync::run"],
    "post-update-cmd": ["SanderMuller\\PackageBoostPhp\\Scripts\\AutoSync::run"]
}

The callback lives under this package's own namespace, so you reference only package-boost-php and never need to require sandermuller/boost-core separately — one package is the whole install. AutoSync::run delegates to boost-core's engine and inherits every guard unchanged (it's silent on a no-op install, skips on --no-dev, and honours BOOST_SKIP_AUTOSYNC). For a script you invoke yourself (e.g. composer sync-ai) where silence reads as nothing happening, use SanderMuller\PackageBoostPhp\Scripts\AutoSync::runWithSummary instead — it always prints the one-line summary.

BOOST_SKIP_AUTOSYNC=1 disables the callback.

Public API

The semver-protected surface — the AutoSync composer-hook façade, the bin/package-boost-php CLI contract, and the managed-block marker format — is documented in PUBLIC_API.md. Everything else is @internal.

Testing

composer test       # Pest suite
composer qa         # Rector + Pint + PHPStan + .gitattributes validator
