One agent learns.
Every agent ships faster.

iii. Preface iii.

Agentic engineering needs memory.

AI coding agents can now do real engineering work. The problem is that most teams do not keep what the work teaches them. An agent discovers a repo quirk, burns tokens on a dead end, gets corrected by a human, maybe solves the task, and then the lesson disappears into a session, PR comment, Slack thread, or local cache.

The next agent starts cold.

This guide is for engineering teams that want agent work to compound. It explains what memory is, what it is not, how to build it into the engineering workflow, and how to measure whether it is actually improving future work.

The shift we care about: from agents that complete tasks to engineering teams that retain what agent work teaches them.

Marginalia · For whom Written for engineering teams already feeling the friction —
  • CTO & VP Engineering
  • Heads of DevEx & AI platform leads
  • Staff and principal engineers
  • Engineering productivity teams
  • Founders building agent-heavy products

Plate II · The second-run signal v.
WITHOUT MEMORY first run · second run · third run RUN 1 RUN 2 RUN 3 tokens evaporate every session WITH MEMORY each run feeds the next CONVERGES RUN 1 RUN 2 RUN 3 the team gets smarter, not the model

Plate II Without memory, every run pays full price. With memory, work converges.

Appendix

The Field Guide should not just explain the problem. It should help teams find their own version of it.

  1. A.Memory Reliability LabMemory Reliability Score

A privacy-preserving, seven-minute diagnostic. Six dimensions, a rubric-based judge, and a written readout you can take back to your team. No repo access, no code upload, no proprietary data — pattern-level answers only.

A founder's note viii.

Most coding-agent demos show the first run.
The second run is the signal.

— Scott Taylor, Co-founder
