## Projects

- [hint](https://openhint.dev/) (source: https://github.com/open-hint-dev/hint): Spec-as-Source for any repository. Intent lives in Markdown-native `.hint` files scoped by path and inherited from the root down — retrieval before the work, deterministic emission between, drift detection after. No model in the loop. Install: `npm install -g @openhint/cli`.
- [acp2api](https://github.com/neprel/acp2api): An OpenAI-compatible HTTP server in front of ACP agents. Use Claude Code, Codex or any ACP agent from anything that speaks the OpenAI API — each agent you configure becomes a model id, and it spends the subscription the CLI is already signed into. Apache-2.0. Install: `npm install -g acp2api`.
- [agent2you](https://github.com/neprel/agent2you): Deploy a team of chat-resident AI agents from declarative manifests. Each agent is one container — chat presence, failover, and a coding agent as the brain, each signed into its own subscription. No provider API keys anywhere. MIT. Install: `uvx agent2you bootstrap`.

## MCP servers

- [mattermost-boards-mcp](https://github.com/neprel/mattermost-boards-mcp): MCP server for Mattermost Boards.
- [mattermost-playbooks-mcp](https://github.com/neprel/mattermost-playbooks-mcp): MCP server for Mattermost Playbooks.
