pi-autothink

Every message, the AI decides how deep to think

A single-file open-source extension for the Pi coding agent: each incoming message is scored 0–5 by TypeSafe JEV, then the active model thinking level is set to match. Same model, same context, only the level changes. Across 224 real messages collected over six days, 86% scored 2 or below.

In its own words · pi-autothink 是给 Pi 用的单文件开源扩展：每条消息先由一个分类器模型判断这件事需要多少思考（0–5 分），再把当前模型的思考档位调到对应那一档；模型不换，上下文不变，只换档位。

For: Developers who use Pi and are tired of flipping the thinking-level switch by hand

Kaikouba

See the Chinese, say it in English

Each English sentence is broken into steps — phrases first, then the whole sentence — built while reading the Chinese prompt.

Free, no sign-up, and your voice is never stored.

It covers 8 everyday scenes (help, dining, shopping, transport, lodging, directions, small talk, work) at three levels (CEFR A1–B1), 720 sentences in all. No sign-up; voice is used only for recognition and never stored; no pronunciation scoring.

Herdr Portal

One keystroke to see what every agent in herdr is doing

A global board plugin for herdr: every agent in your session — across workspaces, tabs and panes — aggregated into one live board that shows who is waiting on you, who is still running and who has gone idle. Ctrl+B then A opens the TUI board in the terminal and Enter lands you in that agent’s pane; Ctrl+B then Shift+A opens the web big-screen, where you reply to a blocked agent straight from the browser. Rename panes, tabs and workspaces in place, and reclaim idle panes to free memory. Open source under the MIT license.

In its own words · Mission control for every Herdr agent. One plugin aggregates every workspace / tab / pane in your Herdr session into a single live board, in two forms: a TUI board you open with Ctrl+B then A, and a web big-screen dashboard you open with Ctrl+B then Shift+A.

For: herdr users running several agents, keyboard-first in the terminal
