Rebuild All Test Components

Run from the repository root:

cargo make build-test-components

This is the authoritative full rebuild. It builds repository prerequisites including golem-cli and the TypeScript SDK, then runs test-components/build-components.sh rebuild across its Rust, TypeScript, and benchmark arrays. Those arrays and list-groups output define the scope used by CI; do not maintain a second component list in this skill.

Do not build the golem package as a substitute for golem-cli. The component script honors GOLEM_CLI and resolves the Cargo target directory; never hardcode target/.... Every mutating golem build invocation must include --yes.

Keep Automatic Migrations

Record the existing status under test-components/ before the rebuild. The latest locally built Golem binary may migrate component source directories while rebuilding them, updating manifests, embedded skills, or other current-format metadata. Inspect newly produced source changes to confirm they came from the rebuild, then keep and include every such migration in the changeset, even when it is unrelated to the original reason for rebuilding. Do not revert or omit migrations to reduce the diff; a full rebuild also advances test components to the current Golem format.

Scope Exception

The full rebuild intentionally excludes two tracked minimal component-model-async fixtures:

• cargo make build-concurrent-delivery-order-component
• cargo make build-concurrent-runtime-events-component

Run those dedicated tasks only when their sources or committed WASMs must change. They validate their outputs and the resulting WASMs remain tracked; ordinary generated test-components/*.wasm files remain gitignored.

TypeScript Caveat and Prerequisites

build-test-components depends on build-sdk-ts, which skips work if both the SDK dist directory and wasm/agent_guest.wasm already exist. This does not prove freshness. After TS SDK changes, clean and rebuild the SDK and agent template before the full rebuild.

Required tools follow current CI and scoped SDK instructions: Rust targets, cargo-make, Node/pnpm, WASI SDK, and the configured wasm-rquickjs-cli version. Read sdks/ts/AGENTS.md and .github/workflows/ci.yaml rather than copying versions into this skill.

Focused Alternatives

Use ./build-components.sh rust, ts, benchmarks, or a listed chunk (rust-N, ts-N) when a full rebuild is unnecessary. ./build-components.sh list-groups is the CI matrix source. Use the modifying-test-components skill for one component.

Validation

After completion:

1. Check each selected application's copy destination exists and is non-empty; do not accept only intermediate golem-temp artifacts.
2. Compare produced top-level WASM names/count against the selected arrays and inspect build failures rather than repeatedly rerunning everything.
3. Use wasm-tools validate --features all for suspicious or structurally changed artifacts.
4. Run the smallest relevant worker/integration/CLI test group.

Generated artifacts are prerequisites, not unit-test work: unit tests must never spawn Cargo, Golem, npm, or compilers. Do not add backwards-compatible build paths for removed component layouts.
