Compatibility
Compatibility for Starter Kit 1.2.0, KOS Community 1.0.0, and the Core 1.0.0 contract. The release validates instruction adapters and installer paths; it does not imply every provider product or integration is supported.
AI environments
| Environment | Starter Kit | KOS Pro | Verification scope |
|---|---|---|---|
| Codex | Adapter validated | Not announced | Optional instruction adapter; requires your own tool access. |
| Claude Code | Adapter validated | Not announced | Claude adapter and supported CLI workflow; not a claim about every Claude application. |
| Gemini | Adapter validated | Not announced | Optional Gemini adapter; your provider tool needs its own setup. |
| ChatGPT | No release validation | Not announced | Codex validation does not establish ChatGPT application integration. |
| MCP-compatible clients | No release validation | Not announced | Instruction adapters do not establish a shipped or validated MCP connection. |
| Obsidian (interface) | Optional interface | Not announced | Markdown-compatible workspace and additive vault enhancement. Plugin-specific behavior and all link forms were not exhaustively tested. |
Systems and runtimes
| Installer path | Prerequisites | Release evidence |
|---|---|---|
| Windows / PowerShell | PowerShell 5.1 or 7; no Python dependency. | Native PowerShell path documented; cross-platform CI reported. |
| macOS or Linux / Bash | Bash 4+ with Python 3.10+. | Bash path documented; cross-platform CI reported. |
| Existing vault changes | Full external backup, reviewed dry-run, then explicit approval. | New, supported upgrade, and Obsidian enhance operations documented. |
These are documented paths, not a guarantee for every OS version, distribution, plugin, or filesystem. The release notes disclose a skipped Windows symlink-permission test.
