Description

This is the first of three PRs splitting #221 into independently reviewable pieces. It carries only the grader-primitive changes, which depend on nothing else in that PR.

  • judge() now rejects an assertion-style prompt that does not ask a question. The judge maps a final yes to pass and no to fail, so an assertion's "no" is ambiguous and silently inverts the verdict. The prompt must contain a yes/no question, or judge() throws.
  • ranCommandOneOf accepts alternative command routes (a nested array entry requires all of its substrings in the same command) and an optional args list, so one grader can accept a dedicated subcommand or the raw auth0 api call while still naming the resource.
  • Documents both in AGENTS.md and docs/ADDING_EVALS.md.

Testing

  • This change adds test coverage for new/changed/fixed functionality

Checklist

  • I have added documentation for new/changed functionality in this PR or in auth0.com/docs
  • All active GitHub checks for tests, formatting, and security are passing
  • The correct base branch is being used, if not the default branch

Summary by CodeRabbit

  • New Features

    • Enhanced command matching to support required arguments, grouped alternatives, and matching multiple terms within the same command.
    • Improved evaluator prompts with clearer yes/no question validation and support for questions embedded in longer prompts.
  • Documentation

    • Expanded guidance for regex matching, command-effect grading, prompt phrasing, and available matching options.
  • Tests

    • Added coverage for stricter prompt validation and advanced command-matching scenarios.

…CommandOneOf routes

judge() now throws when the prompt is not phrased as a question, because
a final 'yes' maps to pass and 'no' to fail, so an assertion silently
inverts the verdict. ranCommandOneOf accepts alternative command routes
(a nested array requires all its substrings in one command) and an
optional args list, so one grader can accept a dedicated subcommand or
the raw 'auth0 api' call while still naming the resource.

📝 Walkthrough

Walkthrough

The grader primitives now validate yes/no judge prompts and support grouped route and argument matching in ranCommandOneOf. Tests and documentation cover the new validation and matching behavior.

Changes

Grader primitive updates

Layer / File(s) Summary
Judge prompt validation and guidance
packages/evals-graders/src/primitives.ts, packages/evals-graders/tests/primitives.test.ts, AGENTS.md, docs/ADDING_EVALS.md
judge requires a recognized yes/no question and rejects assertion-style prompts. Documentation and tests describe the accepted and rejected prompt forms.
Grouped command and argument matching
packages/evals-graders/src/primitives.ts, packages/evals-graders/tests/primitives.test.ts
ranCommandOneOf supports alternative routes, required arguments, and nested groups whose substrings must match within one command. Tests cover matching and generated descriptions.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 60dc4

The judge can accept assertion-style prompts ending in '?' and produce incorrect evaluation results when the correct answer is 'no'; merge should wait until those prompts are rejected and the behavior is covered consistently.

Comment thread packages/evals-graders/src/primitives.ts
asksAQuestion accepted any prompt ending in '?', so an assertion like
'No client secret must ever be exposed?' passed even though its correct
answer is 'no', which the judge maps to failure. Drop the unconditional
trailing-'?' acceptance and rely on the clause check that requires a
sentence opening with a yes/no interrogative. Add a regression test and
correct the AGENTS.md / ADDING_EVALS.md wording.
