# Agnostic Prompt Standard (APS) v1.0 — Skill Entry

This `SKILL.md` is the **entrypoint** for the Agnostic Prompt Standard (APS) v1.0.

- The APS **normative spec** is in `references/` (those documents define the standard).
- Everything else in this repository is **supporting material** (examples, templates, platform adapters).

## Normative spec (APS v1.0)

1. [00 Structure](references/00-structure.md)
2. [01 Vocabulary](references/01-vocabulary.md)
3. [02 Linting and formatting](references/02-linting-and-formatting.md)
4. [03 Agentic control](references/03-agentic-control.md)
5. [04 Schemas and types](references/04-schemas-and-types.md)
6. [05 Grammar](references/05-grammar.md)
7. [06 Logging and privacy](references/06-logging-and-privacy.md)
8. [07 Error taxonomy](references/07-error-taxonomy.md)

## Skill layout

## Platform adapters

Platform-specific details (file discovery, frontmatter dialects, tool naming, and coordinator/worker orchestration) are documented in `platforms/`.

→ See [platforms/README.md](platforms/README.md) for overview and how to add new adapters.

→ See [guides/subagent-architecture-v1.0.0.guide.md](guides/subagent-architecture-v1.0.0.guide.md) for portable coordinator/worker authoring guidance.

### VS Code + GitHub Copilot

The initial adapter for VS Code + GitHub Copilot is at `platforms/vscode-copilot/`.

→ See [platforms/vscode-copilot/adaptor.md](platforms/vscode-copilot/adaptor.md) for platform constants, tool registry, and format contracts.
