CHAPTER 03 · BUILD

Agents Shipped Inside the Existing Stack

The first system, and the two right behind it, shipped inside the plant's existing systems — no new platform, no ERP migration. Each one is real and running.


THE AGENTS · 3 FOR THIS WORKFLOW

This floor needed three. The number isn't a package — it's however many distinct jobs the work splits into. Each agent is a separate identity with its own scoped tools and permissions.

IT DOESN'T STOP AT A REPORT

The Agent Takes the Action

A report is one thing these agents produce. Most of what they do is take the next action inside the plant's own systems — a person approves anything that carries risk.

DATA VIEW

Draft the maintenance work order

When a cell trend crosses the line, the agent opens the work order in the CMMS, pre-filled, and routes it for one-click sign-off.

Send the coaching ask to the floor lead

The ranked ask lands in the right person's queue to accept or send back — nobody goes hunting for it.

Ran automatically

Write the fix back to the knowledge base

An accepted fix is logged to the shared, searchable history — not left in one veteran's memory.

Ran automatically

Commit the schedule change

Once approved, the cell-balance reassignment is written straight to the scheduler.

Ingest

Automated

Live shift data pulled from the robotic cell logs each rotation — no new sensors, no new data entry.

Fan out by role

Automated

One data pull becomes four reports — plant manager (strategic), floor lead (execution), per-operator (skill-aware coaching), and the daily huddle agenda — each grounded in the same numbers.

Ground every claim

Automated

Every recommendation cites the exact log entry or benchmark behind it, not a general opinion.

Floor lead review

Reviewer input

Each recommended ask is one-click accept or reject. Rejections become training signal for tomorrow's report.

Tomorrow's diff

Automated

The next huddle opens with a diff against today's accepted asks — did it work, what changed.

REAL OUTPUT · REGULATED DOCUMENT EXTRACTION

One Example, Fully Processed

When a job calls for a written artifact, this is what the system produces — everything it finds, structured for the action it triggers next.

GD&T Callouts Extracted

Callout Value Datum Feature Confidence
Positional ⌖ 0.10mm A-B-C Primary mounting bore 96%
Perpendicularity ⊥ 0.05mm A Mounting face 94%
Parallelism ∥ 0.08mm B Flange face 91%
Runout ⟲ 0.06mm A Outer diameter 68%
Surface finish Ra 1.6 Mating face 98%

Part Summary — for Quoting

Precision Flange Bracket, ANSI B, 6061-T6 aluminum. Four positional/geometric callouts plus one surface-finish spec. The primary mounting bore carries the tightest tolerance on the print — ±0.10mm positional to datum A-B-C — that's the quoting driver. Everything else on this part sits inside the shop's standard capability band.

Tough Areas — Floor's First-Article Briefing

Primary mounting bore: tightest tolerance on the print. First-article inspection required before the run starts.
Outer-diameter runout callout extracted at 68% confidence — below the auto-log threshold. Verify against the original drawing before committing to the tolerance.
Flange-face parallelism is achievable on the standard fixture, but watch for chip buildup affecting datum B on longer runs.

WAVE 2 — IN BUILD

Cell-Balance & Scheduling — What's Next

Cell 4 (5-axis setup) and Cell 13 share overlapping part families and tool commonality. When both queue a job at once, one waits — and the wait isn't always assigned to the cheaper option.

The agent proposes a reassignment; a constraint solver checks the math. Nothing ships on an LLM's arithmetic — the solver's answer is the answer, the agent just explains it.

Worked example the solver evaluates today in testing

Job 1182 (Cell 4) and Job 1191 (Cell 13) both queue at 9:40 AM. Four reassignment options scored by projected cycle-time delta:

DATA VIEW
4 No change — first-in, first-served +34 min combined wait
3 Hold Job 1191 for Cell 4 availability +18 min combined wait
2 Split setup — shared fixture prep +9 min combined wait
1 Reassign Job 1182 to Cell 13 (tooling overlap) +2 min combined wait

WHAT CHANGED

Time returned

~90% of manual writeup time

Floor leads got the time back for coaching and setup reduction, not for a longer report.

Operating complexity

A reconstructed-from-memory huddle became a reviewed, one-click-accept brief
