sayane 1.0.3

Local-first persona and context portability for cross-LLM collaboration

Sayane (紗綾音)

日本語版 README

Sayane is a local-first persona/context portability tool for cross-LLM workflows.
It keeps a canonical user context locally, then compiles it for different runtimes (ChatGPT, Claude, etc.).

What this tool does

• Keeps canonical persona/context in a local store (~/.sayane/)
• Compiles one Profile into per-target prompt outputs
• Prevents immediate blind merges (capture → candidate → evaluate)
• Tracks approved/rejected changes as lineage

What you can verify in 5 minutes

Install CLI first (detailed steps: docs/install.md).

# macOS / Linux
curl -fsSL https://raw.githubusercontent.com/zyx-corporation/sayane/main/scripts/install.sh | bash

# Windows (PowerShell)
irm https://raw.githubusercontent.com/zyx-corporation/sayane/main/scripts/install.ps1 | iex

Then verify the core flow:

sayane --version
sayane init
sayane compile --target chatgpt --profile examples/profiles/minimal.yaml

Within 5 minutes, you can verify:

• local profile store initialization
• target-specific prompt compilation from one profile
• the core flow: Profile → compile

Core principles

1. Separate persona from runtime

Canonical persona belongs to local Sayane Profile, not vendor memory.

2. Compile through intermediate representation (Prompt IR)

Do not copy one prompt string across runtimes; re-compile per target.

3. Evaluate meaning changes before merge

capture → candidate → evaluate (RDE/UIB) → approve/reject → lineage
