A personal repository of Agentic prompts, skills, and workflows.
geas-grimoire is a collection of "spells"—the raw prompts, tool definitions, and logic chains used to drive AI Agents.
The name is a thematic nod to my experimental project, geas-ai.
- While
geas-aifocuses on the binding and sealing of agentic artifacts (governance), geas-grimoirefocuses on the invocation—providing the text and logic needed to wake the agents up.
Note: This repository is platform-agnostic. While it shares a naming convention with
geas-ai, these resources are designed to be used freely with OpenCode, ClaudeCode, Antigravity, or your own custom Python scripts.
The repository is organized into three core pillars of agentic development:
The Personas. Contains system prompts and identity definitions. These files define who the agent is and its core behavioral instructions.
- Format: Markdown / Text / YAML
- Usage: Copy the content into your IDE's "System Prompt" field or agent configuration file.
The Rituals. Defines the step-by-step logic for complex tasks. These act as "Standard Operating Procedures" (SOPs) or chain-of-thought templates for multi-step reasoning.
- Content: Logic chains (e.g., Research -> Outline -> Draft).
The Capabilities. A library of tools that agents can use to interact with the world. Each skill has its own dedicated subfolder containing the implementation and the interface definition.
