Defines typed or universal Golem tool middleware in Scala. An agent skill from golemcloud/golem.

  • Adapting tool surfaces
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Golem Tools Middleware Scala is an agent skill from golemcloud/golem. Defines typed or universal Golem tool middleware in Scala. Use for validation, policy, auditing, or adapting tool surfaces.

Its SKILL.md is about 300 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

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

  • Adapting tool surfaces

Example prompts

  • “Use the golem-tools-middleware-scala skill to define typed or universal Golem tool middleware in Scala. An agent skill from golemcloud/golem”
  • “/golem-tools-middleware-scala”

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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are scala).

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

  • Network

    No URLs in SKILL.md.

    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

Golem Tools Middleware Scala loads about 301 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 75 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~301

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 75 words (~301 tokens).

“The build plugin generates Middleware and Underlying from each tool definition. Extend the generated middleware trait and annotate the concrete no-argument class. The example assumes the Echo definition from golem-define-tool-scala.”
