harness

My personal Pi harness: a Pi package of extensions, skills, prompt templates, design doctrine, and shared configuration. I use it to shape how the agent works across projects and machines. It builds on Pi’s own capabilities instead of maintaining a parallel agent core; the durable-harness track records the upstream contracts and when this repository adopts them.

Start with Architecture for installation, how Pi loads the package, and machine configuration.

Contents

• Extensions: executable tools, commands, and interface changes. Each extension directory has its own README.
• Web interface: local browser access to ordinary conversations and Durable agents. Start with npm run ui.
• Skills: task procedures, each defined in a SKILL.md file.
• Prompt templates: operator-invoked shortcuts, including /tldr [hint] for a short, plain-language summary. See the prompt convention for use and ownership.
• Pillars: principles, patterns, and heuristics that guide agent judgment.
• Documentation: architecture and repository conventions.
• Configuration: shared application configuration, with setup in Architecture.
• Evaluations: maintained evaluations and their execution requirements.
• Scripts: repository checks and development automation.

Development

Follow the worktree convention and the repository instructions before changing the harness.
