Six agents, one repo, and the 225 KB file that kept tripping them
July 21, 2026
Running four to six Claude Code sessions against the same repo at once kept ending the same way: crashes, wasted tokens, and agents convinced they were 2–3 commits behind main. The culprit was a 225 KB file none of them could hold in context cleanly. Not a coordination problem. Not a merge conflict. A single oversized file quietly breaking every session's mental model of where the repo stood.
Six concurrent Claude Code sessions, one repo, constant crashes. The agents kept reporting they were 2–3 commits behind main. They weren't. A 225 KB file was eating their context before they could form an accurate picture of the codebase.

Six Claude Code sessions hitting the same repo at once, all crashing in the same way: convinced they were 2–3 commits behind main when they weren't. The real culprit was a single 225 KB file. Not a git problem, not a concurrency problem. Just one file too large for any session to fully hold, quietly corrupting every agent's read of the repo state.
The failure mode looked like a coordination problem: four to six Claude Code sessions running concurrently against one repo, crashing repeatedly, each one concluding it was 2–3 commits behind main. Classic multi-agent chaos, right? Wrong. It was a single 225 KB file. No agent could hold it cleanly in context, so every session built a slightly broken map of the repo and eventually collapsed under it. The fix had nothing to do with orchestration.
Six Claude sessions, one repo, same crash every time: agents certain they were 2–3 commits behind main. Not a git issue. A 225 KB file was too big for any of them to hold in context cleanly.

Six concurrent Claude Code sessions kept crashing with the same wrong diagnosis: 2–3 commits behind main. The actual problem was a 225 KB file quietly breaking every agent's context before it could get a clean read on the repo.
