Knowledge graphs are emerging as a critical layer for AI agents to overcome 'fragmentation' and 'tool explosion' in enterprise settings.

LLM に渡しているのは、しばしば「パズルのピース」だけです。Confluence、Slack、Jira などから取った断片を、その場でつなぎ合わせるしかない設計では、正答率が安定しにくくなります。

The post argues that LLMs often struggle with complex tasks because they are given only 'puzzle pieces' (fragmented data) without a 'box art' (overall context). It proposes using knowledge graphs as a 'partial solution picture' to provide LLMs with structured context, improving accuracy and handling contradictions, especially in multi-agent and team-based AI scenarios.

New self-monitoring app 'Sentinel' detects 'over-activity' and lack of logging as critical health signals, addressing a gap in traditional wellness tools.

「体調が悪い」だけ見ていても足りなかった。HTML + PowerShellで「元気すぎる」も検知するセルフモニタリングアプリを作った

The author developed a self-monitoring app, Sentinel, after realizing their previous app only tracked negative health changes, missing a period of 'hyperactivity' that preceded burnout. Sentinel monitors both 'over-activity' and 'under-activity' relative to a personal baseline, and crucially, also detects when the user stops logging data, treating it as a signal of potential distress.
