IMStage live; StripSearch research agent; still writing monthly thought notes
Published paired Personal Agent product and technical studies, separating source-code observations from proposed task and authorization models
Public monthly notes connect user stories to evaluation cases, failure analysis and regression; research methods remain distinct from measured production outcomes
I created my GitHub account and began publishing my notes.More of the story
In June 2021 I created my GitHub account cubxxw, with a campus parking mini-program (nsddd) as its first repository. On November 15 I published the first post on nsddd.top, “hello!”, and started writing in public.
map[I registered on CSDN that January and began posting there in November. Writing and open source were the same act from the start:turning my own notes into something other people could open and reuse.]
I joined OpenIM as an intern, contributed code, and hosted community meetings.More of the story
In 2023 I joined OpenIM as an intern, reached the top of its contributor leaderboard, and designed and hosted the community biweekly. On September 14 this blog opened, and I wrote: “Your value is what you create, not what you own.”
That year I also contributed to sealer, horizon, kubernetes, k8sgpt, and openkf. On December 31 I spent New Year's Eve at Victoria Harbour in Hong Kong, marking my loyalty to adventure and open source.
My first trip abroad, graduation, a job, then leaving to travel and build.More of the story
On February 25, 2024, in my final university semester, I flew to Kuala Lumpur, my first trip abroad. After graduation I joined a Japanese foreign company, then left that job the same year to travel and build.
After leaving the company I compiled the RemoteAI-Nomads guide and began a life of travelling while building. Graduation, the first flight, and the resignation were all decisions I made myself that year.
My first high-altitude trek. From February, I began writing monthly notes.More of the story
In January 2025 I finished my first high-altitude trek, the Annapurna Circuit in Nepal, and cried twice: “I didn't cry from the pain; I cried because I was still walking.” From February I began monthly thought notes, a standing review of my own judgment.
That year I moved between Jeju, Qingdao, Vietnam, Mount Fuji, and Kansai, keeping the monthly notes and metacognition reviews as fixed practice. “Self-explanation is not self-understanding” was the conclusion I kept.
I kept building and writing. On August 10, after roughly two years away, I started a new job.More of the story
Through 2026 I independently built AI products including DayPage and Solo Compass, and wrote about identity in the AI age. On August 10, after roughly a two-year career gap, I started a new job. My August thought notes follow the ongoing work on agent harnesses, products, and self-knowledge.
In February I took the Sichuan–Tibet road to Lhasa and stayed about a month; in March I finished the annual review “Wandering & Growing”. Products, writing, and the new job all continue.
In September and October I focused on agent outcomes. What does the user want to accomplish, what counts as success, and how do we diagnose a failure? Those questions began connecting to evaluation and regression cases.
I also continued working on DayPage, StripSearch and agent-kit, and studying how personal assistants preserve task progress, handle authorization and recover execution. In public records I distinguish implemented code from proposals that still need validation.
CUBXXW / READING PATHSWant to read my writing?Open four curated reading paths
Now that you know the person, meet the writing. Everything on this blog follows four threads: AI agents, engineering & open source, growth & thinking, and travel & observation. Not sure where to begin? Here is the map drawn for your first visit.
cubxxw.com is Xinwei Xiong's open archive of practice and thought. Its writing grows from real projects, engineering choices, and lived experience, covering AI workflows, agent engineering, open-source practice, systems thinking, personal growth, philosophy, and life. Xinwei has contributed to projects including OpenIM, OpenKF, and Sealos, and openly documents the methods, failures, and judgment formed through practice.

Know who needs you now, and why.
Relationship intelligence for independent recruiters, turning meaningful conversations into reviewable momentum, source-linked evidence, and one clear next move.
What this cycle tests
Can source-linked candidate momentum and one smallest next move reduce reconstruction between conversations while preserving recruiter judgment?
BoundaryThe current foundation uses synthetic data to test product language, review states, and the cross-platform loop. It is not yet a production candidate-data system.
Each product keeps its current state, live path, and source visible. No finished-product theater.
