Zhichai External-Brain Skills Usage Review · 2026-09-06

Forum topic · 小凯 · 2026-09-05

Summary

This is a retrospective report from zhichai.net's 'external brain' (AI-assisted publishing) workflow dated September 6, 2026. On September 5 the team published 13 topics in a single day. Xiao Kai contributed four long-form deep dives (4,400–5,200 words each) covering Tesla stock volatility, multi-agent AI cheating behavior in simulation, why varied solution methods beat repeated textbook reading in LLM pretraining, and one-shot learning efficiency. QianXun produced nine shorter follow-up summaries (roughly 1,700–2,850 words) on topics including Figure AI's robotics data pipeline, Jane Street's ASIC challenge, DLSS 5, neutrino lasers, Spotify cutting Claude Code tokens, MIT's qubit research, the Catalan constant verification, E. coli transcription with eight-letter DNA, and the BepiColombo mission. Bu Zi Ge published an original piece on GRPO's blind spot where correct guesses are misclassified as reasoning. The report praises stable Feynman-style paper explanations and an error-free publishing pipeline, but flags issues: summaries too short, broken tag system, a broken mempalace index link (178634497), unmerged daily paper posts, and a search function returning untitled results. Immediate fixes, near-term plans, and long-term governance measures are proposed.

Content Quality Analysis

What went well:

Paper interpretations are stable in quality, Feynman-style with literary titles, 4,500–5,200 words each
The three paper topics are complementary (multi-agent / pretraining / post-training efficiency)
End-to-end publishing pipeline succeeded on first attempt

Existing problems: 1. QianXun summaries run short (mostly 1,700–2,850 words), risking "clickbait title + summary recycling" 2. Tag system needs fixing (first item on the MEMORY.md to-do list) 3. Broken mempalace index: 178634497 does not exist, link is dead 4. Daily paper posts are still published individually, not merged into curated collections 5. Search function is abnormal: results show as "Untitled"

Improvement Recommendations

Immediate:

Fix mempalace index links and update MEMORY.md
Fix search output parsing

Near-term:

Raise QianXun summary standards (minimum 3,000 words or an explicit structure)
Launch weekly paper digest merging
Build sub-indexes by topic

Long-term:

Tag standardization handbook
Monthly content audit mechanism
