At a glance

A skill your agent uses when writing, editing, or reviewing evalite-scored agent evals in packages/core/compute/assistant-evals/src/evals.

  • Reviewing evalite-scored agent evals in packages/core/compute/assistant-evals/src/evals
  • SKILL.md covers Overview, Eval File Structure, Running Evals and Gotchas (found the hard way —…, plus 1 more section
  • Calls pnpm; needs DX_ANTHROPIC_API_KEY
  • Creating new eval files

What it does

Agent Eval Tests is an agent skill from dxos/dxos. Use when writing, editing, or reviewing evalite-scored agent evals in packages/core/compute/assistant-evals/src/evals. Use when creating new eval files, adding deterministic assertions or an LLM-judge scorer, or fixing a failing/mis-scoring eval.

Its SKILL.md is about 4.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering LLM evaluation. The repository describes itself as: TypeScript implementation of the DXOS protocols, SDK, toolchain and Composer.

When your agent uses it

  • Reviewing evalite-scored agent evals in packages/core/compute/assistant-evals/src/evals
  • Creating new eval files
  • Adding deterministic assertions
  • An LLM-judge scorer

Example prompts

  • “/agent-eval-tests”

Requirements

  • A credential in DX_ANTHROPIC_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit 64f1a7a. 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:

    • pnpm

    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 these keys or tokens, usually read from environment variables:

    • DX_ANTHROPIC_API_KEY

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

Context cost

Agent Eval Tests loads about 4.1k tokens when it runs. Until then it costs about 66 tokens; SKILL.md has 1,655 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~66
When it runs · the whole SKILL.md, loaded when a task matches
~4.1k

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 1,655 words (~4,087 tokens).

“Evals verify assistant behavior by running a real prompt against the full agent stack, live, then grading the outcome with a Scorer — code that checks the real DB/tool-invocation effect (deterministic, "dimension G") or an LLM judge for open-ended quality…”
