README

A prompt catalog for the Semitexa Framework — an "ORM for prompts".

LLM prompt text tends to sprawl: system prompts hard-coded as heredocs at every call site, few-shot examples buried inline, no way to see what was actually sent. This package gives prompts the same treatment the framework gives skills and translations: discoverable, addressable, composable records.

What it gives you

• Models — a PromptTemplate is the durable, id-keyed record of a prompt.
• A repository — PromptRegistry discovers every #[AsPrompt] class and exposes the catalog behind PromptRepositoryInterface.
• Relationships — templates compose via partial includes ({{> other.id }}) and bind runtime data via variables ({{ name }}).
• Observability — prompt:list / prompt:show / prompt:render let you inspect exactly what an LLM would receive, before you send it.

The package is provider-agnostic: it renders text and role-tagged messages, never a wire format. A downstream adapter (e.g. in semitexa/llm) maps a RenderedPrompt onto whatever the provider needs.

Defining a prompt

use Semitexa\Prompt\Attribute\AsPrompt;
use Semitexa\Prompt\Domain\Contract\PromptDefinitionInterface;

#[AsPrompt(id: 'os.planner', channel: 'os', description: 'OS planner system prompt')]
final class OsPlannerPrompt implements PromptDefinitionInterface
{
    public function system(): string
    {
        return <<<'PROMPT'
        {{> core.identity }}

        Plan the task for {{ user }}. Today is {{ date }}.
        PROMPT;
    }
}

Ship few-shot examples by also implementing FewShotProviderInterface.

Rendering

$renderer = new PromptRenderer();

$rendered = $renderer->render('os.planner', [
    'assistant_name' => 'Semi',   // consumed by the {{> core.identity }} partial
    'user' => 'Taras',
    'date' => '2026-07-13',
]);

$rendered->system;    // fully-resolved system text
$rendered->messages;  // few-shot messages, variables bound

Rendering is fail-closed: an unbound variable, an unknown partial, or a partial cycle raises PromptRenderException rather than sending a half-substituted prompt.

CLI

prompt:list [--channel=os] [--json]
prompt:show --id=os.planner [--json]
prompt:render --id=os.planner --var=user=Taras --var=date=2026-07-13 [--json]

Roadmap

Phase 1 (this package): catalog + composition + render/inspect tooling. Phase 2: migrate the framework's inline system prompts onto the catalog. Phase 3 (optional): a DB-backed, per-tenant override layer modeled on semitexa/locale — live-editable prompts with catalog fallback and versioning.
