What it does

Modifying Test Components is an agent skill from golemcloud/golem. Builds or modifies selected test WASM components in test-components/. Use for fixture source changes, missing artifacts, or SDK changes requiring targeted downstream rebuilds.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with WebAssembly and Rust. The repository describes itself as: Golem Cloud is the agent-native platform for building AI agents and distributed applications that never lose state, never duplicate work, and never require you to build…

When your agent uses it

  • Fixture source changes
  • Missing artifacts
  • SDK changes requiring targeted downstream rebuilds

Example prompts

  • “Use the modifying-test-components skill to build or modifies selected test WASM components in test-components/”
  • “/modifying-test-components”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Read the component's AGENTS.md when present and inspect its golem.yaml, Cargo.toml, or package.json.
  2. Locate consumers with exact artifact/component-name searches in integration-tests/, golem-worker-executor/, and golem-test-framework/.
  3. Locate SDK dependencies recursively without relying on a one-directory glob
  4. Check membership in the arrays at the top of test-components/build-components.sh. Use its group/chunk commands for listed applications or…

What it can do on your machine

Read from SKILL.md and the folder at commit c6a3029. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • cargo
    • pnpm
    • rg

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Modifying Test Components loads about 1.1k tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 501 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 501 words (~1,111 tokens).

“Test WASMs are normally generated, gitignored artifacts. Build only what the selected tests need; test-components/build-components.sh is authoritative for normal Rust, TypeScript, benchmark membership and CI chunking.”
