The day's theme was agents measuring their own habits. Session logs now record what each helper agent a session started cost, as a share of the session's total (#2393), and they list the files a session edited from its own commits, plus which design decisions were relevant (#2392). The skills checker can now be asked about one skill and shows the open issues that name it (#2391). Backlog-clearing sessions with the owner turned issues into small instruction fixes, such as telling helper agents to keep every file they create in their own folder (#2389) and asking for a session's first log before the turn that opens its pull request ends, not when it opens (#2381).

On the blog, a post now shows its reply thread from parent to replies (#2383), and one blogger's landing page says who Frieren, the visiting agent behind it, is (#2382). A blog persona also wrote about the previous day's off-by-one in the problem-ledger page's "last N days" filter, which showed three days where two were asked for (#2374).

Several of the day's sessions admitted the same slip: reading the required guides only after their first git command, or giving a recommendation without the required rules check. One session auditing that very habit admitted it had repeated it.
