▪ Help me when I’m outside of my comfort zone ▪ Mostly using Claude Code and Cursor nowadays But I never keep much as I care deeply about code, its aesthetic and how it's organized LLMs for coding
tasks ◦ Things that should be automated as no to little value ◦ I know exactly how they should be done ▪ But I want the generated code ◦ To be as deterministic as possible ◦ To feel like I’ve done it myself Boring tasks
“agent” ▪ Control the generated code precisely ▪ Little human interaction ▪ Little code review needed ▪ Reach almost 100% accuracy ▪ Make it cheap ▪ Avoid vendor lock-in Packaging recurring tasks

Help removing deprecations and using new features ▪ Carefully build the context with deterministic data: ◦ Facts about the code base: PHP version, Symfony version, ... ◦ Relevant upgrade guides only (with before/after examples), written and optimized for LLMS ◦ Determine files that need to be updated ◦ ...
classes using the `AsCommand` PHP attribute, we must use the new `help` property instead of calling the `setHelp()` method in the `configure()` method. *Before* ```php #[AsCommand( name: 'app:add-user', description: 'Add a new user' )] class SomeCommand { protected function configure(): void { $this ->setHelp(<<<TXT The <info>%command.name%</info> command adds a new user with the username passed to it: <info>php %command.full_name% jane-doe</info> TXT); } } ```
help: <<<TXT The <info>%command.name%</info> command adds a new user with the username passed to it: <info>php %command.full_name% jane-doe</info> // ... TXT, )] class SomeCommand { protected function configure(): void { $this ->setCommand('username', InputArgument::REQUIRED) ; } } ``` Remove the `configure()` method if it does not do anything anymore after the changes.
better compose generated files and allow for updating existing ones more easily. ▪ We are already upgrading existing files (like Doctrine entities), but updating the default base template, which can diverge drastically from the default, is way more complicated. Maker Bundle
automatically resolve conflicts when possible. ▪ It could also open the door to recipe composition (by assembling small snippets). Security configuration is a good example. recipes:update conflict resolver
local ones (Ollama, vLLM), they all speak HTTP ▪ Symfony already solved this: Symfony HTTPClient powers 40+ Mailer/Notifier bridges. The same pattern works perfectly for LLMs ▪ Additional challenge: many LLM apps need streaming support Talking to AI? It's just HTTP Symfony HTTP Client component
business rules ▪ Twig already solves this: filters, conditionals, inheritance for clean prompt assembly ▪ System prompts are just templates: version control, test, and iterate like any other code Build better prompts with Twig Twig
workflows, outcomes become unpredictable. Use Symfony Workflow to: ◦ Define explicit states and transitions ◦ Set guardrails and business rules ◦ Let AI decide within boundaries you control ◦ Handle human-in-the-loop before proceeding to the next step Keep AI workflows deterministic Symfony Workflow component
what's needed for the task ▪ Improve model accuracy ▪ Decrease costs (less tokens) ▪ Improve performance (less tokens) ▪ Rule of thumb: a human should enjoy reading the context Optimize the context
--format=json ◦ Container information: var/cache/dev/App_KernelDevDebugContainer.* ◦ Routes info: var/cache/dev/url_*.php ◦ ... ▪ Expose profiler info for a specific request like logs, exception messages, configuration, ... ▪ Help answer questions like "give me all command classes" (avoiding the use of grep in a loop by LLMs) Tools via console commands/API?
...), maybe split into many files ▪ Specialized guides that explain how to solve specific tasks (add authentication, ...) ▪ Great pull request descriptions Anything optimized for LLMs is great for human as well Better documentation
