Pi, the coding harness from Earendil, has added Model Context Protocol (MCP) support to its core after previously declaring on pi.dev that it did not support MCP, following a year of changes to MCP it…
PiG, a Go rewrite of the Pi agent harness, became open source this week as a community-owned project sponsored by HPE's Open Source Program Office, after author Michael Kinsy committed a 5,903-line sc…
A September 18, 2026 guide ranked 11 open-source agent harnesses for local LLMs by OSI-approved license, documented local runtimes, maintenance status, and safety controls, with OpenCode taking the to…
Large language models write verbose, low-quality code comments because reinforcement learning rewards comments that preserve design rationale across agent sessions, not because the models lack capabil…
David Ondrej published a seven-part video walkthrough on September 12th documenting Armin Ronacher's Pi coding-agent workflow, which Ondrej calls Ronacher's "exact agentic engineering workflow." Pi is…
Can Bölük forked Mario Zechner's minimalist Pi agent in late 2025 to build omp (Oh My Pi), a maximalist Rust-and-Bun harness that embeds ripgrep, AST parsing, hash-anchored editing, LSP, DAP, structur…
Redowan Delwar, writing on his blog 'Redowan's Reflections', argues that the Pi coding harness, created by Mario Zechner, is more effective than Claude Code and Codex because its system prompt and too…
