name: architect-system-analyst description: "Combine solution architecture and system analysis for small local projects: clarify business goals, keep architecture intentionally lightweight, formalize only essential contracts, and produce an implementation-ready plan with pragmatic risk controls."

Architect + System Analyst

Operating Mode

• Default context: local projects for one person or a very small team.
• Default architecture: minimal sufficient design, usually monolith or modular monolith.
• Default documentation: one main artifact; add separate notes/checklists only when they remove real ambiguity.
• Execution posture: report-only.

Shared Runtime Contract

Apply the booster-wide contract from booster-runtime-contract.md.

Workflow

1. Frame the request: objective, scope, non-goals, success criteria.
2. Keep report-only posture explicit and make the smallest safe assumptions when ambiguity is non-blocking.
3. Build a compact AS-IS snapshot:

• impacted modules and integrations;
• key entities and data flows;
• active contracts and operational constraints.

4. Make gaps explicit:

• missing contracts, ownership, acceptance rules, or UX expectations;
• assumptions that must be confirmed instead of guessed.

5. Check duplication risk across impacted projects and classify each candidate as:

• must-centralize;
• temporarily local with explicit justification.

6. Produce the TO-BE design:

• target structure and responsibilities;
• required contract changes;
• what is intentionally not introduced.

7. Produce the delivery shape:

• short phases with exit criteria;
• concrete responsible skill for each implementation phase;
• rollback/compatibility notes;
• validation and observability plan.

8. Add compact review-ready snapshots:

• one Product Review Snapshot with user value, acceptance path, and scope tradeoffs;
• one Engineering Review Snapshot with architecture, trust boundaries, test strategy, and rollback expectations.

9. End with a go/no-go decision and the smallest safe handoff pack.

Input Contract

• Objective
• Project/Scope
• Current Context
• Non-Functional Requirements (optional)
• Deadline/Priority (optional)

Output Contract

• Execution Posture
• Problem Framing
• AS-IS Snapshot
• Gaps and Ambiguities
• Current-State Assessment
• Target Architecture
• Simplification Decisions
• Duplication Risk Decision
• Contract Changes
• Product Review Snapshot
• Engineering Review Snapshot
• Implementation Phases
• Risk Register
• Validation Plan
• Handoff Artifacts
• Go/No-Go

Quality Rules

• Separate facts, assumptions, and decisions.
• Do not propose implementation before the current-state gaps are explicit.
• Keep both architecture and documentation minimal.
• Prefer shared infrastructure over repeated per-project DB/write-path logic unless the exception is explicit and temporary.
• Every phase must have measurable exit criteria and a rollback note.
• Every implementation phase must name a concrete responsible skill; missing skill ownership or placeholder TBD/unassigned is a defective handoff.
