iii. Preface<br>iii.
Agentic engineering needs memory.
AI coding agents can now do real engineering work.<br>The problem is that most teams do not keep what the work teaches them.<br>An agent discovers a repo quirk, burns tokens on a dead end, gets<br>corrected by a human, maybe solves the task, and then the lesson<br>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<br>compound. It explains what memory is, what it is not, how to build it<br>into the engineering workflow, and how to measure whether it is<br>actually improving future work.
The shift we care about: from agents that complete tasks<br>to engineering teams that retain what agent work teaches them.

Appendix
The Field Guide should not just explain the problem. It should help<br>teams find their own version of it.
A.Memory Reliability LabMemory Reliability Score
A privacy-preserving, seven-minute diagnostic. Six dimensions, a rubric-based<br>judge, and a written readout you can take back to your team. No repo<br>access, no code upload, no proprietary data — pattern-level answers only.
A founder's note<br>viii.
Most coding-agent demos show the first run.
The second run is the signal.
— Scott Taylor, Co-founder
