The editable source is skills/yii2-select2/SKILL.md. It guides Select2 configuration, ActiveForm validation, remote data, and lifecycle cleanup using the installed package’s contracts.

Install the Select2 skill

Automatic Composer installation

Use the one-time application setup with auto-sync set to true in skills.json, approving yii2-extensions/select2 explicitly. The package declares skills as its bundle source. For an installed release containing the skill:

composer install
composer skills:show

With auto-sync enabled, composer install and composer update synchronize the skill automatically. If it is false, run composer skills:update after dependency installation or updates.

For a release without the bundle, register a source checkout once instead:

composer skills:add /absolute/path/to/select2 --skill=yii2-select2

Optional manual installation

Copy or link the complete yii2-select2 skill directory from a package checkout or from vendor/yii2-extensions/select2/skills/ into the application client’s project skill path:

Client	Project skill path	Explicit activation
Codex	.agents/skills/yii2-select2/SKILL.md	$yii2-select2 or the skill picker
Claude Code	.claude/skills/yii2-select2/SKILL.md	/yii2-select2
OpenCode	.opencode/skills/yii2-select2/SKILL.md, or .agents/skills/	Load yii2-select2 through its skill tool

Keep one effective installation per client. A Composer installation in vendor/ alone does not expose the skill to an agent opened at the application root. Refresh a copied directory when upgrading the package; edit the package source instead of maintaining a separate set of instructions.

See Claude Code skills and OpenCode skills for client discovery rules.

Yii framework skill

For Yii 22 conventions, use the yii2-framework workflow from the common skill package. The one-time Composer application setup installs it together with the other framework skills. The same auto-sync setting and manual synchronization step apply. Keep one framework donor in the application configuration.

For optional manual installation, copy the complete skills/yii2-framework/ directory from a common-package checkout, including its referenced resources, into the client project path above. Verify discovery in the client. For Yii 2.0 applications, use matching framework contracts; do not apply Yii 22-only setup automatically.

Choose matching documentation

Resolve yii2-extensions/select2, yiisoft/yii2, and any optional theme or validation adapter separately. Use each package’s actual installation path and Composer-selected reference; for live checkouts, the current files and HEAD govern, including uncommitted changes. A lockfile may describe a different state from the installed files.

When a matching deployment of the shared documentation site provides llms.txt, read that index and fetch individual Markdown pages by appending index.md to their URLs. A development version label alone does not establish a matching source revision. Use the installed package’s docs/, PHPDoc, source, and changelog when hosted guides are missing, unavailable, or describe a different revision. Both the Select2 skill and these guides are included in the package archive.

Verify installation and use

Open a fresh client session at the application root, inspect its skill list, then explicitly invoke yii2-select2 for a small form task. File installation, client discovery, instruction loading, and a working integration are separate checks. Automatic selection depends on the client and model.

A copied skill resolves its resources from the installed package rather than relative to the copied directory. Verify generated forms, server validation, browser events, and cleanup in the consuming application.
