Rstack context

@rstackjs/context is the runtime behind the Rstack project-context MCP. It records and queries checkout-local build, lint, test, coverage, and Rsdoctor evidence while keeping freshness, completeness, and provenance explicit.

Most users install and invoke it through the rstack package:

rs mcp

The rstack/context export re-exports this package for programmatic consumers. Codex and Claude Code workflow guidance is distributed separately by rstackjs/agent-skills.

corepack enable
pnpm install
pnpm check
pnpm build
pnpm test

The package uses Rslib for builds, Rstest for tests, and Rslint for lint and type-aware checks. Rsbuild remains a public integration surface for build-context observers. See the context engine RFC for the runtime architecture and evidence semantics.

Execution coverage evidence is optional and resolved against the package under test, not against @rstackjs/context itself: install @rstest/coverage-istanbul (or another supported Rstest coverage provider) as a dependency of the checkout being analyzed for coverage evidence to be captured. @rstackjs/context does not declare that provider as a peer dependency.
