Herdr and the Agent Multiplexer Gap: Why tmux Alone Isn't Enough
Once you run several coding agents at once, plain terminals and classic multiplexers stop being enough. Herdr fills the gap between tmux and agent apps.

Kimi K3: What a 2.8T Open Model Changes for Engineers
I spent a weekend with Moonshot's Kimi K3 launch notes and tech report. The useful story is not leaderboard rank. It is systems: sparse MoE, long context, open weights, and what it takes to run a 3T-class agent brain.
How omp Runs Subagents Differently
Most coding agents treat a subagent as a nested chat that returns prose. omp gives workers typed results, direct peer messages, and safer shared-file edits.
Pi Agent: The Minimal Harness That Became My Multi-Tool Glue
After 2 months switching between Claude Code, Codex, Gemini CLI, and Pi Agent for different coding tasks, Pi's 'primitives not features' philosophy turned it into the connective tissue between heavier tools.
Tau: The Open-Source Agent You Read Like a Textbook
HuggingFace's Tau is the first coding agent built to be understood. Its 200-line loop confirms what I suspected after 2+ years inside Claude Code, Cursor, and Codex: the architecture is universal, the magic is in the harness.
