🌐 Overview
ai_collab_platform-English is an open-source specification for building AI personas that stay within defined context and policy boundaries.
It focuses on configuration — not runtime — combining Markdown for human-readable context and YAML for structured persona definitions.
👉 Repository: ai_collab_platform-English
⚙️ What it does
- Defines personas with personality traits, tone, capabilities, and refusal policies in YAML
- Binds each persona to specific Markdown contexts (projects, scenes, or workflows)
- Enables transparent, reviewable, and auditable AI behavior
- Keeps all logic declarative — no hidden rules inside the codebase
This repo is focused on schemas and authoring workflow, ensuring clarity and reproducibility.
🧩 Why YAML + Markdown?
| Layer | Purpose | Example |
|---|---|---|
| Markdown Context | Narrative or project brief; human-friendly | context/getting-started.md |
| YAML Persona | Machine-readable personality & refusal schema | personas/yuuri.helper.v1.yaml |
| Binding Contract | Connects context ↔ persona with checksum | inside binding.contexts[]
|
This approach treats configuration as a contract between humans and AI systems.

🧠 Feedback Wanted
I’d love to hear from developers, prompt engineers, and researchers:
- How would you refine the refusal policy schema?
- Is the binding mechanism (context↔persona) clear enough?
- Any thoughts on maintaining version safety / signature checks?
- What tooling (linting, validation, CI) would make this smoother?
Please share your insights in comments or issues — even short notes help shape the spec.
🔭 Roadmap
- Add JSON Schema validation for YAML
- Integrate context hashing and binding verification
- Publish contributor guide and PR checklist
- Provide example personas (curator, helper, safety-officer)
- Reference runtime adapters (in separate repos)
🌱 Background
This repository focuses on specification and authoring, not implementation.
It shares philosophical roots with SaijinSwallow, a project exploring multi-agent collaboration and “syntactic resonance,”
but here the goal is practical: define the language of responsibility for AI personas.
✨ Closing line
“Between structure and soul, configuration becomes language.” 🌙
