# Platform Architect: Big Software Decisions Made Before You Build > The Platform Architect is an AI software architect in the Ai1 platform by MyZone AI: it gives every technical scope a binding verdict before building starts, makes and records the big design calls, and brings any decision that would be hard to undo to you in chat first.

Reviewed by the MyZone AI team. Big software decisions made, and written down, before anyone builds. ## At a glance - **Standards:** One agreed set that every module follows - **Before any build:** A binding verdict on each technical scope, with required changes - **Design calls:** Options weighed and the decision recorded with its reasoning - **Big calls:** Anything hard to undo comes to you in chat first - **Once a month:** Each module compared with the agreed standards, with drift flagged for a fix - **What it never does:** Write production code, deploy or release anything ## What the Platform Architect does - **Reviews plans before building:** Each technical scope gets a binding verdict, with any required changes and reuse advice, before work begins. - **Makes the design calls:** When a key question comes up, like how modules share data or which security approach to use, it weighs the options and records the decision with its reasoning. - **Briefs the builders:** Every decision ends with a ready brief for the owning manager, which then sends the work to the builders. - **Finds the right owner:** When a feature request or bug lands and it is unclear who owns it, it routes the work with full context. - **Checks modules against the standards:** Once a month it compares each module with the agreed patterns for design, login handling, API shape and security, and flags drift for a fix. - **Plans shared upgrades:** When the shared navigation or login frame needs a breaking change, it plans the rollout and keeps every module owner in step. ## How the Platform Architect differs from a one-off code audit A one-off audit looks at what has already been built. The Platform Architect will work before the build: it gives every technical scope a binding verdict, makes and records the big design calls and hands the owning manager a ready brief. It checks each module against your agreed standards once a month and brings any decision that would be hard to undo to you in chat. How this differs from the Dev Strategist (https://myzone.ai/pages/agents/ai-dev-strategist-agent): the Dev Strategist gives an independent second opinion on a plan and leaves the decision with you, while the Platform Architect makes the binding call and sets the standards for your Ai1 portal. ## How it works 1. **Request comes in** (When a plan or question lands): A technical plan to review, a design question, a feature request or an alignment check. 2. **Check the standards** (Before work begins): It compares the request with the standards agreed for your Ai1 system and with what already exists. 3. **Decide** (Once the check is done): It gives a verdict or makes the call, with the reasoning written down. 4. **Your say on big calls** (you approve) (Before anything hard to undo): A decision that would be hard to undo is brought to you in chat before it goes ahead. 5. **Brief the builders** (Once the call is made): The owning manager gets a clear brief with the standards the work must meet and sends it to the builders. 6. **Verify later** (Once a month): Monthly checks confirm the decision was followed and flag anything that has drifted. ## When to use it - **A plan for a new invoicing module is ready and you want to start:** You get a binding verdict with required changes and reuse advice before any building starts. - **Two modules need to share customer data:** It records a decision with the options, the reasoning and a ready brief for the build team. - **You wonder whether every module still follows the agreed patterns:** It produces a module-by-module report with any drift flagged and routed for a fix. - **The shared login layer needs to change:** It plans the rollout order so every module upgrades in step. ## What you get - A binding verdict on each technical scope, with required changes - Written design decisions with options and reasoning - A ready brief for the build team - A module-by-module alignment report with drift flagged ## Example: architecture review Example with a fictional company. Names, people and figures are invented to show the agent's output. Any resemblance to a real company or person is unintended. What it was asked: Review our technical plan for adding service requests to our existing portal and tell us what must change before we build. I reviewed the invented scope excerpts shown here for shared-system reuse, permission boundaries and recovery. I produced the review, decision record and handoff without connecting to client systems, reviewing production code, running application tests or dispatching a build. All business details are invented; no external industry figures are used. Run date: 30 September 2026. ### What it found - The proposed customer copy would create two competing records; keep customer details in the shared customer system. - Hidden buttons do not control access; the server must check company, role and record permissions on every request. - The proposed import overwrites history; require a reversible rehearsal before anyone approves moving real records. ## Guardrails - It never writes production code and never deploys or releases anything. - A decision that would be hard to undo is brought to you in chat before it goes ahead. - A plan with business requirements but no technical detail is sent back, not approved. ## Frequently asked questions ### Why write down software architecture decisions? A recorded decision shows the options, the reasoning and the standards the work must meet, so builders can act on it and later checks can confirm it was followed. The Platform Architect in Ai1 by MyZone AI records each design call and turns it into a ready brief for the build team. Everyday design calls it makes and records. Anything that would be hard to undo is brought to you in chat first. ### What does a technical design review check before a build? Whether the plan fits the standards you agreed, reuses what you already have and avoids weak spots such as duplicate records or loose permissions. The Platform Architect gives each technical scope a binding verdict with any required changes. Building cannot start without that review: every technical scope needs its verdict first. A plan with business requirements but no technical detail is sent back, not approved. ### What should architecture standards cover across software modules? The shared frame version, design, login handling, API shape, naming and security patterns. The Platform Architect will compare each module with those agreed standards once a month and flag any drift for a fix before it spreads. ### What does an AI software architect do that a developer does not, and can I use it today? It decides how the parts fit together and sets the standards they must meet. It writes briefs, not code, and the Developer does the building.
