# Without Intelligent Guardrails, Claude Code Is Pure Chaos

## Summary
DevArch adds automatic engineering guardrails to Claude Code so AI-assisted development keeps project context, test quality, architectural decisions, and domain boundaries across sessions.

## Problem
- Claude Code can make one developer move faster, but the excerpt says speed can produce inconsistent architecture, weak tests, and lost context across sessions.
- The problem matters because small teams using AI agents still need durable decisions, clear module boundaries, and tests that prove real behavior instead of shallow checks.
- The target user is a subject matter expert, developer, or QA role trying to run more of the software delivery loop with Claude Code.

## Approach
- DevArch plugs into Claude Code through directives, agents, skills, and lifecycle hooks that run without the developer calling them manually.
- Session start hooks restore context, pre-session audits surface blockers, work summaries capture state, and architecture decision records preserve approved decisions.
- Before implementation, the system pushes domain-driven design work such as bounded contexts, ubiquitous language, domain events, aggregates, and value objects.
- Before side-effect code and cross-boundary state edits, agents require structured declarations such as owner, shared state status, promise, alternatives, behavior, timing, reason, and rejection conditions.
- Test checks grade behavior-derived tests as RED, YELLOW, or GREEN and reject tautological assertions, mock-only checks, and return-value-only tests.

## Results
- The excerpt reports no benchmark, user study, defect-rate reduction, throughput measure, or comparison against vanilla Claude Code.
- It claims budget tracking warnings at 70%, 90%, and 100% of the tool-call budget for each phase.
- It claims each session gets a unique 6-character hex ID so concurrent Claude Code sessions in the same repository do not collide on gate files, budget tracking, or file change state.
- It claims hooks ship for 2 shell environments, Bash and PowerShell, covering Windows, macOS, and Linux.
- It claims every significant decision can become an ADR with context, rationale, and consequences, but the excerpt gives no count, adoption rate, or quality metric for this process.
