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…
