Use before hand-writing infrastructure or utilities such as a lock, a queue, a cache, an HTTP client, mail, scheduling, rate limiting, shell commands, slugs or file searches, or before adding a third-party library for one of these.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
2 rules. 0 are common, 1 is distinctive, and 1 is very specific to this project.
0
Common
Most of the 5 edited versions we read keep these.
1
Distinctive
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 11
Before hand-writing infrastructure, or adding a third-party library for it, check whether a Symfony component covers it.
- Very specific: line 36
Check symfony.lock first; the project may already have it.
“Common” is measured: kept by at least 6 in 10 of the 5 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Reach for the component
Before hand-writing infrastructure, or adding a third-party library for it, check whether a Symfony component covers it. It usually does. The check costs one look; the hand-rolled version costs whoever maintains it.
The map
| The task needs | The component |
| a job that must not run twice at once | symfony/lock: LockFactory, or LockableTrait in a command |
| work moved off the request | symfony/messenger: a message class, #[AsMessageHandler], an async transport |
| recurring jobs defined in PHP | symfony/scheduler |
| calling an HTTP API | symfony/http-client: HttpClientInterface, one scoped client per API |
| caching a computed value | symfony/cache: CacheInterface::get() with a callback |
| sending mail | symfony/mailer: MailerInterface, an Email object |
| throttling logins or API calls | symfony/rate-limiter |
| a status field with rules about transitions | symfony/workflow |
| unique identifiers | symfony/uid: Uuid or Ulid |
| time you need to control in tests | symfony/clock: ClockInterface, ClockAwareTrait |
| running an external program | symfony/process: Process, never exec() or shell_exec() |
| a URL-safe slug from a title | symfony/string: SluggerInterface, not a preg_replace chain |
| mapping JSON or arrays to objects | symfony/serializer |
| finding files by pattern or age | symfony/finder: Finder, not a hand-rolled recursive iterator |
Using one
Check symfony.lock first; the project may already have it. If not:
symfony composer require symfony/lockThe Flex recipe wires the default configuration. Do not copy configuration by hand from a blog post when a recipe exists.
This is not a rule to use every component. It is an order of operations: look first, write
code second. A while loop polling a database column is not a queue, a static array is
not a cache, and a timestamp column checked before sending is not a lock.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
