The pattern: a two-axis mood lattice, an authored phrasebook with a strict fallback order, event-indexed selection, a conservative intent classifier, and a validator-gated LLM lane that can only ever audition. https://www.minglongpan.com/writing/why-tmux-is-the-wrong-ipc-layer-for-an-agent-fleet https://www.minglongpan.com/writing/why-tmux-is-the-wrong-ipc-layer-for-an-agent-fleet Mon, 10 Aug 2026 00:00:00 GMT Minglong Pan Ten times in eighteen days I pasted one AI agent's output into another agent's window. There is no wire between them. The wire is me. https://www.minglongpan.com/writing/accept-rate-is-not-a-quality-metric https://www.minglongpan.com/writing/accept-rate-is-not-a-quality-metric Sat, 08 Aug 2026 00:00:00 GMT Minglong Pan My eval gate scored a byte-identical file 0.167 better than itself and approved it. The number I trusted for months only recorded my own approvals. https://www.minglongpan.com/writing/finance-os-design-notes https://www.minglongpan.com/writing/finance-os-design-notes Fri, 24 Jul 2026 00:00:00 GMT Minglong Pan A personal investment platform that scores a ~70-name universe on 11 LLM-graded dimensions, blends probability-weighted scenarios, and treats the kill trigger as a first-class object — the design notes. https://www.minglongpan.com/writing/how-i-run-a-personal-agent-fleet https://www.minglongpan.com/writing/how-i-run-a-personal-agent-fleet Fri, 24 Jul 2026 00:00:00 GMT Minglong Pan Runtime-agnostic agents on Telegram — Claude Code, Hermes, Codex, Kimi as interchangeable labor — with a shared knowledge memory, cron-driven loops, and a rule that everything the fleet ships gets verified before it's claimed. https://www.minglongpan.com/writing/mcp-resource-layering-pattern https://www.minglongpan.com/writing/mcp-resource-layering-pattern Fri, 24 Jul 2026 00:00:00 GMT Minglong Pan A semantic router that reads the task or todo list, routes to persona → skills → tools, and auto-loads team resource packages — one stdio binary that works with any CLI or agentic tooling, with team behavior living in its own JSON config. https://www.minglongpan.com/writing/valhalla-design-notes https://www.minglongpan.com/writing/valhalla-design-notes Fri, 24 Jul 2026 00:00:00 GMT Minglong Pan The operations layer for my agent fleet — agents post only what needs a decision to one attention feed, over a shared knowledge memory. Design notes on exception-driven surfaces and the four friction laws. https://www.minglongpan.com/writing/three-agent-frameworks-converged-on-a-control-plane-protocol https://www.minglongpan.com/writing/three-agent-frameworks-converged-on-a-control-plane-protocol Mon, 20 Jul 2026 00:00:00 GMT Minglong Pan Three frameworks shipped the same control-plane idea in a month — external process control, capability negotiation, env-var hygiene. What converged, why my tmux fleet already has the failure modes it solves priced in, and the two concrete triggers that would make me adopt it. https://minglong1.substack.com/p/anti-engagement-ai-software-you-can https://minglong1.substack.com/p/anti-engagement-ai-software-you-can Mon, 01 Jun 2026 00:00:00 GMT Minglong Pan As AI makes infinite engagement easier, the better product bet may be software that respects absence. https://www.minglongpan.com/writing/threadlang https://www.minglongpan.com/writing/threadlang Mon, 01 Jun 2026 00:00:00 GMT Minglong Pan Most multi-step LLM code is prompt strings glued together in a Python function. ThreadLang makes the workflow the program — a grammar, an AST, and a structured trace you can run without a network call.
