Repo Test Architect

Audit-first test strategy tooling for codebases.

Repo Test Architect builds a deterministic audit graph before asking any model or agent to reason about tests. The goal is to identify repo-native, high-value test work from facts the tool can inspect locally: project roots, framework signals, existing tests, source classifications, blockers, and remaining risk.

The current implementation can:

• audit JavaScript/TypeScript, PHP, Python, Ruby, and Swift projects through supported adapters
• audit supported, bounded Kotlin/JVM fixtures through the same shared artifact model
• audit conventional Go modules and literal repository-contained go.work members through a supported bounded adapter
• audit conventional Cargo packages and literal repository-contained workspace members through a supported bounded Rust adapter
• audit one conventional SDK-style C# test project or one unique literal production/test project edge, including bounded native xUnit MTP-v2 and MSTest.Sdk v4 ownership, literal and one-hop root-aliased target frameworks, one repository-contained direct *.cs compile include, finite target-conditioned package shapes, bounded nearest-file build and central-package props, exact immutable test-field receivers, stable direct-call results, inline out results, framework exception and collection/string assertions, one-hop test helpers, and guarded well-known System type collisions, through a supported bounded .NET adapter
• audit one conventional Composer/PSR-4 project with PHPUnit through a supported bounded PHP adapter
• audit one conventional Mix application with exact MixProject/Mixfile, bounded source and Mix-task ownership, literal local ExUnit wrapper discovery, and test-body evidence through a supported bounded Elixir adapter
• detect polyglot project roots and report unsupported ecosystems without hiding them
• produce a complete repository analysis, findings, ranking, plan, execution hints, and verification commands in one audit pass
• classify source files by likely test value and defer low-value direct tests
• rank candidates and generate test plans from the audit graph
• derive provider-neutral execution, context, parallel-safety, and repository-reasoning hints without selecting models or spawning subagents

Native test generation is intentionally deferred. generateselectedtest returns a structured deferred artifact until adapter-specific generation policy and repair-loop fixtures exist.

Repo Test Architect 1.0.0-beta.2 is available as an opt-in public beta on npm and the Official MCP Registry. The unqualified npm command remains on 0.3.0 while the beta is evaluated. Treat its findings as evidence-backed review input rather than an automatic instruction to change a repository. See the beta release notes.

Beta.2 adds experimental Dart/Flutter support and adapter trust fixes. The @beta commands below select beta.2; see the release notes and validation plan. Dart remains experimental, and native generation remains deferred.
