Last night my agent told me this would speed things up. I pressed my agent to explain WHY this morning. What he ended up saying was that this cleanup has no effect. How sessions.json actually works according to my bot reading the docs: Sessions.json is cached and your bot reads from disk cache with a 45-second TTL. The flow: 1. First read: readFileSync > JSON.parse > result stored in an in-memory Map 2. Subsequent reads within 45s: returns the cached clone > no disk read, no parse 3. Cache invalidates if: TTL expires, file mtime changes, or file size changes 4. On invalidation: re-reads from disk, re-parses, re-caches So the answer to "does it parse on every startup/lookup" is no. It parses once, caches for 45 seconds, and only re-parses if the file actually changed. Dozens of session lookups per minute hit the in-memory cache, not the filesystem. Other relevant details from the source docs...this process already happens: • Default rotate threshold: 10 MB (DEFAULT_SESSION_ROTATE_BYTES) ... when sessions.json exceeds 10 MB, OpenClaw rotates it to .bak.{timestamp} & keeps only the 3 most recent backups. • Default max entries: 500 • Default prune-after: 720 hours (30 days) So for my 5.3 MB file, it's under the rotation threshold, parsed once every 45 seconds at most. So yes this file grows constantly! Every cron fire, every inbound message, every subagent spawn triggers updateSessionStore. If you have ~100 cron fires/day plus your messages to your bot & subagents, that's easily 200-400+\ writes/day. But that's all disk related not context related. I pressed my bot on Opus 4.6 high if this was causing context bloat and his answer was: "No. sessions.json is not injected into the prompt. sessions.json is a routing index — it maps session keys to metadata (which session file to load, what model to use, delivery context, token counts). It's used server-side by the gateway to figure out where to send your message. The LLM never sees it." So I'm now even more confused...do we need to bother doing this or will OpenClaw take care of this naturally with the automatic rotation & pruning process? I guess I should look at who exactly wrote this code and then try to ask them directly ...








🚨FYI: Gavin Newsom has already signed California Assembly Bill 1043 which mandates that operating systems including Windows, Linux, macOS, and FreeBSD implement system-level age (identity) verification. This takes effect on January 1st, 2027. Colorado also has a similar act called SB26-051 which is currently advancing through the committees and ready for full Senate consideration. It would come into effect on January 1st, 2028 if passed. Utah, Texas, Louisiana, and Alabama all currently have app layer verification laws, but not OS level YET. So OS level verification isn't a future thing. It's happening now. They are chokepointing the internet. Enjoy these days.
