First public release of the field report.
A candid, dated field report on building a multi-country document-compliance agent in full-AI mode on Copilot Studio (snapshot: August 2026, GPT-5.5 baseline, GPT-5.6 compared).
What's inside
- Architecture — an agent flow that owns pagination + five single-purpose agents.
- Execution walkthrough — one full loop, step by step, with observed timings.
- Data contracts & the deterministic output pattern — "the model judges, scripts build".
- Harness limits (flagship chapter) — the constraint -> decision table, including "agent laziness".
- Model selection — GPT-5.5 vs GPT-5.6: quality vs cost & latency.
- Where to remove AI in production — the de-AI map.
- Safeguards — the "never do this" list.
- Reproduce it — table structure + wiring, no client data.
Notes
- Client-neutral: all data, documents, tenant and organization details removed; the running example is fictional.
- The two analyst skill packages are intentionally not shipped (client-derived).
