Non-engineer built an iPhone-only AI ops system, asks what breaks first
CellAgentLab · reddit · 2026-09-27
A non-engineer Japanese founder shares a small-business operations system built entirely on an iPhone with ChatGPT, Google Drive, scheduled tasks, and browser AI tools, asking for honest critique of failure modes.
Early failures: scheduled tasks fired without proof of completion; external actions became uncertain after timeouts; retries could duplicate side effects; memory went stale; technical success was easy to confuse with business success; the AI kept going after tool failures and still produced plausible answers.
Design responses:
- Google Drive as source of truth; structured state, registries, and execution evidence
- A Run Audit per execution; TECHSTATUS and BUSINESSSTATUS tracked separately
- UNCERTAIN state when external results can't be confirmed, no blind retries, idempotency checks
- Freshness checks before execution; human approval for high-impact actions
- Regression cases built from past failures; AI for ambiguous judgment, deterministic code for state, logs, deadlines, and math
The loop: Retrieve → Understand → Decide → Act → Verify → Reconcile → Record. Action permissions stay narrow while the AI reasons broadly. He asks what would break first if this ran continuously for months or years.
