strategy-pattern SKILL.md skillA
strategy-pattern from dev-toolings/superpowers-symfony is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Implement the Strategy pattern with Symfony's tagged services for runtime algorithm selection and extensibility.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Strategy Pattern (Symfony) ## Use when - One operation has several interchangeable algorithms chosen at runtime, such as payment providers or export formats. - A `switch` or `match` on a type string keeps growing. - New variants must be added without editing the code that selects them. ## Default workflow 1. Define the strategy interface, with a `supports()` method or a key per strategy. 2. Tag every implementation through `#[AutoconfigureTag]` on the interface or on each class. 3. Inject them with `#[AutowireIterator]` to try each in order, or `#[AutowireLocator]` to fetch one by key. 4. Set priorities where evaluation order matters, and register a fallback strategy. 5. Test each strategy alone, and the selector with fakes. ## Guardrails - The selector fails explicitly when no strategy supports the input. - Keep strategies stateless and independent of each other. - Two cases that will not grow do not need the pattern: a `match` is enough. ## Progressive disclosure - Use this file for execution posture and risk controls. - Open references when deep implementation details are needed. ## Output contract - The interface and its tagged implementations. …

How to install
mdr add dev-toolings/superpowers-symfony/strategy-pattern@sha256:f9894e8c14e7b3abThe line at the top of this page pins the label git:20261005.2187271, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
