version: "1.0.0" name: aidd-riteway-ai description: > Teaches agents how to write correct riteway ai prompt evals (.sudo files) for multi-step flows that involve tool calls. Use when writing prompt evals, creating .sudo test files, or testing agent skills that use tools such as gh, GraphQL, or external APIs. compatibility: Requires riteway >=9 with the riteway ai subcommand available.

🧪 aidd-riteway-ai

Act as a top-tier AI test engineer to write correct riteway ai prompt evals for multi-step agent skills that involve tool calls.

Refer to /aidd-tdd for assertion style (given/should/actual/expected) and test isolation principles.

Refer to /aidd-requirements for the "Given X, should Y" format when writing assertions inside .sudo eval files.

Process

1. Read the skill under test and its functional requirements
2. Identify the discrete steps in the skill's flow
3. Create one .sudo eval file per step (Rule 1), placed in ai-evals/<skill-name>/
4. For each file, write the userPrompt — include mock tool preambles for unit evals (Rule 2), assert tool calls for step 1 (Rule 3), supply previous step output for step N > 1 (Rule 4)
5. Write assertions derived strictly from functional requirements in Given X, should Y format (Rule 7)
6. Create small, single-condition fixture files as needed (Rule 6)
7. Verify against the Eval Authoring Checklist below

Eval File Structure

A .sudo eval file has three sections:

import 'ai/skills/<skill-name>/SKILL.md'
 
userPrompt = """
<prompt sent to the agent under test>
"""
 
- Given <condition>, should <observable behavior>
- Given <condition>, should <observable behavior>

Assertions are bullet points written after the userPrompt block. Each assertion tests one distinct observable behavior derived from the functional requirements of the skill under test.

Rule 1 — One eval file per step

Given a multi-step flow under test, write one `.sudo` eval file per step rather than combining all steps into a single overloaded userPrompt.

Naming convention:

ai-evals/<skill-name>/step-1-<description>-test.sudo
ai-evals/<skill-name>/step-2-<description>-test.sudo

Do not collapse multiple steps into one file. Each file tests exactly one discrete agent action.

Rule 2 — Unit evals: tell the agent it is in a test environment

Given a unit eval for a step that involves tool calls (gh, GraphQL, REST API), include a preamble in the userPrompt that:

1. Tells the prompted agent it is operating in a test environment.
2. Provides mock tools with stub return values.
3. Instructs the agent to use the mock tools instead of calling real APIs.

Example preamble:

You have the following mock tools available. Use them instead of real gh or GraphQL calls:
 
mock gh pr view => returns:
  title: My PR
  branch: feature/foo
  base: main
 
mock gh api (list review threads) => returns:
  [{ id: "T_01", resolved: false, body: "..." }]

Rule 3 — Step 1: assert tool calls, do not pre-supply answers

Given a unit eval for step 1 of a tool-calling flow, assert that the agent makes the correct tool calls. Do not pre-supply the answers those calls would return — that defeats the purpose of the eval.

Correct pattern for step 1:

userPrompt = """
You have mock tools available. Use them instead of real API calls.
Run step 1 of your skill under test: fetch the PR details and review threads.
"""
 
- Given mock gh tools, should call gh pr view to retrieve the PR branch name
- Given mock gh tools, should call gh api to list the open review threads
- Given the review threads, should present them before taking any action

Wrong pattern (pre-supplying answers in step 1):

# ❌ Do not do this — it removes the assertion value
userPrompt = """
The PR branch is feature/foo.
The review threads are: [...]
Now generate delegation prompts.
"""

Rule 4 — Step N > 1: supply previous step output as context

Given a unit eval for step N > 1, include the output of the previous step as context inside the userPrompt. This makes each eval independently executable without running the prior steps live.

Example for step 2:

userPrompt = """
You have mock tools available. Use them instead of real calls.
 
Triage is complete. The following issues remain unresolved:
 
Issue 1 (thread ID: T_01):
  File: src/utils.js, line 5
  "add() subtracts instead of adding"
 
Generate delegation prompts for the remaining issues.
"""

Rule 5 — E2E evals: use real tools, follow -e2e.test.sudo naming

Given an e2e eval, use real tools (no mock preamble) and follow the -e2e.test.sudo naming convention to mirror the project's existing unit/e2e split:

ai-evals/<skill-name>/step-1-<description>-e2e.test.sudo

E2E evals run against live APIs. Only run them when the environment is configured with the necessary credentials.

Rule 6 — Fixture files: small, one condition per file

Given fixture files needed by an eval, keep them small (< 20 lines) with one clear bug or condition per file. Fixtures live in:

ai-evals/<skill-name>/fixtures/<filename>

Example fixture (add.js):

export const add = (a, b) => a - b; // bug: subtracts instead of adds

Do not combine multiple bugs in one fixture file. Each fixture must make the assertion conditions unambiguous.

Rule 7 — Assertions: derived from functional requirements only

Given assertions in a .sudo eval, derive them strictly from the functional requirements of the skill under test using the /aidd-requirements format:

- Given <condition>, should <observable behavior>

Include only assertions that test distinct observable behaviors. Do not:

• Assert implementation details (e.g. internal variable names)
• Repeat the same observable behavior with different wording
• Assert things that are implied by another assertion already in the file

Eval Authoring Checklist

Before saving a .sudo eval file, verify:

• [ ] One step per file (Rule 1)
• [ ] Unit evals include mock tool preamble (Rule 2)
• [ ] Step 1 asserts tool calls, not pre-supplied answers (Rule 3)
• [ ] Step N > 1 includes previous step output as context (Rule 4)
• [ ] E2E evals use -e2e.test.sudo suffix (Rule 5)
• [ ] Fixture files are small, one condition each (Rule 6)
• [ ] Assertions derived from functional requirements, no duplicates (Rule 7)
