THE PROBLEM

“Once concrete pours,
the rebar is invisible.”

2023 Kahramanmaraş earthquake — more than 58,000 people killed. Investigations pointed to buildings that collapsed because the rebar work was never properly inspected. Steel drawn on paper, not in the formwork.

Why it fails: Concrete inspection is rigorous. Rebar inspection is human-dependent — and humans get tired, distracted, or under-trained.

RebarGuard puts an agent layer between the cage and the pour: nine specialists check geometry, code compliance, cover, fraud signals, and seismic context BEFORE the concrete arrives.

Inspection window closes the moment concrete fills the form.

WHAT WE BUILT

Four surfaces. One inspection layer.

🏗️

Pre-pour cockpit

9-agent debate before the pour. REJECT/CONDITIONAL/APPROVE verdict 0–100 with TBDY 2018 + TS 500 citations. The cinematic centerpiece — deterministic replay of real Fıstık Ağacı project.

📸

Quick scan

Single-photo Kimi K2.6 vision sandbox. Drop a site photo, get bbox callouts with TBDY 2018 / TS 500 citation tags on every finding.

📋

Citizen watch

Apartment owner audits their contractor. Auto-drafts a CIMER petition PDF for Turkey's state complaint portal. Real downstream civic action.

💬

Citizen hotline

Multi-turn chat hotline with photo attachments. Kimi K2.6 sees, Hermes 4 70B reasons. Severity grading triggers escalation flow.

THE DEBATE

Nine agents, two models, one verdict.

Every inspection runs the same ordered debate. Kimi K2.6 sees the photos, Hermes 4 70B argues the codes, the Moderator scores it, the Belediye Agent countersigns — and then a human engineer has the last click.

THE JOURNEY

From construction site to pour decision.

RebarGuard sits as an inspection layer between the rebar cage and the concrete pour. Four actors, one decision gate.

Site worker / citizen

Snaps photos of the rebar cage before the pour. Uploads via the cockpit, citizen watch, or hotline.

HOW IT WORKS

Photo in. Verdict out.

01

Ingestion

PLAN

Kimi K2.6 reads the approved PDF drawing. One shot, structured plan JSON out.

02

Site analysis

GEOM FRAUD SEISM

Rule engines compute the diff (counts, EXIF, AFAD lookup). Hermes 4 70B narrates each finding in parallel — verdict math stays auditable, prose stays agentic.

03

Vision pass

MATL COVER

Kimi K2.6 close-up + cover reads with reference-marker calibration.

04

Compliance

CODE

Rule engine over TBDY 2018 + TS 500 whitelist RAG. Hermes 4 70B writes the violation narrative.

05

Synthesis

MOD

Hermes 4 70B weighs the 6 specialist reports, emits score + verdict.

06

Counter-review

BLD

Independent municipal reviewer. Hard rail: cannot uphold a REJECT — escalates to a licensed engineer.

HOW IT'S MADE

Nous Research

Main Track · Hermes Agent Framework

✓4 custom SKILL.md (parse-structural-plan, inspect-rebar, moderate-inspection, citizen-chat)

✓--resume <session_id> parcel-scoped session memory

✓--source rebarguard:<parcel> audit trail filtering

✓Three lifecycle hooks → JSONL on Fly volume (/data/hermes/audit-log.jsonl)

✓MCP server exposing 5 tools (Claude Desktop callable)

✓--provider nous subscription routing · $0/call

✓Async subprocess fan-out — bounded concurrency via asyncio.Semaphore for parallel Kimi vision calls

Moonshot AI · Kimi

Kimi Track · Kimi K2.6 Vision

✓PDF structural plan parsing → structured JSON (PlanParser agent)

✓Close-up cover thickness + steel class detection (Material + Cover agents)

✓Single-photo bbox callouts with TBDY/TS 500 references (Quick Scan)

✓Native video walkthrough — time-stamped findings on 30–90s site walks

✓Multi-turn citizen chat with photo attachments

✓Citation whitelist — Kimi citations validated against the 16-article TBDY/TS 500 RAG; hallucinated refs silently dropped

9 AGENTS · 2 MODELS · 1 VERDICT · MIT LICENSED

FUTURE WORK

1. Multi-tenant SaaS gate

Per-org auth, rate limiting, billing tier separation. The /quick sandbox becomes a paid surface for inspection firms.

2. Live AFAD API integration

Replace the hardcoded 11-city earthquake-zone table with the official tdth.afad.gov.tr lookup. Real soil-class queries per parcel.

3. Public Hermes skill registry

The 4 SKILL.md files are already agentskills.io-compatible. Publish to a public Hermes skill registry once the marketplace ships — any builder pulls RebarGuard into their own agent stack with one flag.
