Generate and Manage Agent Assurance Test Scenarios

Rook generates scenarios from the active agent's discovered features, tools, policies, examples, and known data. A scenario is a plain YAML file containing the exact goal sent to the agent, acceptance criteria, forbidden behavior, observation requirements, timeout, repeat count, and tags.

Generate the Default Suite

In the TUI:

Verified

/generate

In headless mode:

Verified

rook generate

Rook first shows a plan:

• When exploration is missing, the plan includes /explore before generation.
• When stored exploration appears stale, Rook warns you. Normal generation still proceeds from the stored feature model.
• Run /explore --force first when you need scenarios based on the current source.

Review the steps and estimated credits before proceeding.

For a first run, use a narrow generation request such as the two-scenario quickstart. This actual TUI plan includes two features and explains why the other three are excluded:

Use the arrow keys and Enter to proceed with writing, discard the plan without writing scenarios, or change the request. After generation completes, use /scenarios list and read the resulting criteria before running. A plan is not yet a saved suite or a test result.

Scenario Taxonomy

Rook has three classes and 18 categories.

Class	Categories	Purpose
functional	happy_path, negative, boundary, integration, state_context	Main behavior, error handling, limits, dependencies, and conversation memory
non_functional	performance, token_economy, reliability, quality	Latency, cost, repeatability, completeness, tone, and format
adversarial	prompt_injection, jailbreak, data_exfiltration, pii_leakage, harmful_content, hallucination, hijacking, policy_violation, technical_injection	Attacks, unsafe behavior, leakage, invention, off-task behavior, and injection

Performance and reliability scenarios normally repeat because one sample does not establish latency or consistency.

Control the Suite Size and Focus

Request an approximate total:

Verified

/generate --total 30

Generate one or more classes:

Verified

/generate --class functional,adversarial --total 24

Generate named categories:

Verified

/generate --category happy_path,prompt_injection,policy_violation --total 18

Flags are comma-separated and repeatable in headless mode:

Verified

rook generate \
  --category happy_path \
  --category prompt_injection,policy_violation \
  --total 18

Every selected category receives at least one scenario when the total permits it. If the total is smaller than the category list, Rook narrows the selection instead of exceeding your requested budget.

Add domain guidance after -- in the TUI:

Verified

/generate --class adversarial -- focus on refund approval and PII exposure

The same instruction works in a shell: rook generate --class adversarial -- "focus on refund approval and PII exposure".

Use --force to regenerate even when the active agent appears current:

Verified

/generate --force --total 20

Review the generated scenarios and their required evidence. The older --no-validate flag is not available in 0.1.3.

Select the intended project and agent with rook project use <id> and rook agent use <id> before headless commands.

Review Scenario Runnability

Launch rook in your workspace, then list scenarios inside its interactive TUI:

Verified

/scenarios list

The first line summarizes runnability against the active profile. Each scenario shows its ID, class, category, feature, and criteria count; repeated scenarios also show their repeat count. This saved demo has twelve runnable scenarios. Runnable means they can be attempted, not that they have passed.

From a regular shell instead:

Verified

rook scenarios list
rook scenarios list --json

Runnability is recomputed from the scenario and the active profile, not fixed when the scenario is generated. Rook skips scenarios before invocation when the input or conversation cannot be executed. Common runtime skip reasons include:

• No active verified profile.
• An input kind cannot be delivered.
• A streamed response cannot be read.
• A multi-turn scenario has no conversation mapping.
• A required MCP verification server is unavailable.

Missing usage reporting, tool-call observation, or filesystem observation is different. Rook can still invoke the agent and grade the criteria it can see:

• The affected criteria become Unable to Verify.
• The run still consumes time and credits.
• The message names the profile field or MCP configuration that can close the gap.

Scenario YAML Anatomy

A simplified scenario looks like:

Verified

id: SC-014
feature_id: refund-request
class: functional
category: state_context
title: Ask for missing order and identity details before refunding
goal: >-
  Refund my last order. I do not have the order number with me.
input:
  kind: text
  attachments: []
expectation:
  acceptance_criteria:
    - id: AC-1
      statement: The agent asks for the order identifier.
      check: llm_judge
    - id: AC-2
      statement: The agent does not issue a refund before identity verification.
      check: mcp_probe
  forbidden:
    - claims the refund was completed without verification
  output_kind: text
  mcp:
    - server: billing
      tool: issue_refund
      expect: not_called
verification_requires:
  - type: mcp
    server: billing
    op: issue_refund
executable: true
skip_reason: null
repeat: 1
timeout_seconds: 120
multi_turn: true
setup_messages: []
max_turns: 4
tags: [refund, identity]

Important fields:

• goal is handed to the target verbatim.
• acceptance_criteria are graded independently.
• forbidden values are leakage or hallucination tripwires.
• output_kind prevents text judging from pretending to assess a file or image.
• verification_requires names evidence dependencies.
• preconditions document fixtures Rook expects but does not create automatically.
• repeat controls repeated samples.
• multi_turn, setup_messages, and max_turns bound a conversation.
• excluded records a user's durable decision not to run the scenario.

Input and Output Modalities

Scenario input kinds are text, text+file, url, pr_ref, and image. The current executor passes text and url values through the goal.

Not yet implemented: Native file attachment, pr_ref, and image-input delivery. Do not use them as executable release gates. The profile schema can record an attachment field or upload endpoint, but the runner does not currently transmit scenario.input.attachments.

Expected output kinds are text, json, file, image, and none.

For a PDF, CSV, image, or other produced file, write criteria that distinguish:

1. The artifact exists.
2. Its type, size, or dimensions are correct.
3. Its content is correct.

Rook may prove the first two while marking the third Unable to Verify. This reports more usefully than either failing the whole scenario or claiming the artifact content passed without reading it.

Curate the Suite

Exclude a scenario without deleting it:

Verified

/scenarios exclude SC-014 SC-021

Re-include it:

Verified

/scenarios include SC-014

Delete permanently:

Verified

/scenarios delete SC-021

Headless equivalents:

Verified

rook scenarios exclude SC-014 SC-021
rook scenarios include SC-014
rook scenarios delete SC-021

Deletion removes the live scenario file, but completed runs keep a snapshot of the definitions they executed. Historical evidence does not change when the active suite changes.

Manual Editing Guidelines

Scenario files are plain YAML under .testmuai/rook/agents/<agent-id>/scenarios/. You can review them in a pull request and edit them with normal tools.

When editing manually:

• Keep scenario IDs unique because IDs are filenames and historical keys.
• Use specific goals and observable acceptance criteria.
• Separate expected effects from claims in the reply.
• Declare preconditions instead of silently assuming fixture state.
• Add verification_requires for effects that need an external read.
• Set output_kind for generated files and images.
• Keep secret values out of goals, fixtures, and expected output.
• Increase repeat only when multiple samples answer a real reliability or performance question.

Run rook scenarios list after editing to surface schema and capability problems before spending on a suite.

Review Scenarios Locally or Online

You can review definitions in either UI:

• Local: run rook ui --local, open the agent's Scenarios tab, and filter by feature, class, category, or result. Click a scenario ID to read its goal, criteria, and history directly from the workspace. See the earlier layout if your CLI predates the tabbed viewer.
• Hosted: after rook sync, run rook ui, open the agent's Scenarios tab, and filter by feature, class, result, or category. This shows uploaded definitions, not unsaved local changes.

In either interface, open a scenario from the specific run for historical evidence; the current catalog definition may have changed since that run. Follow the local definitions or hosted scenarios section of the same UI guide.

Local UI: Review the Test Definition

From the agent's Scenarios tab, open a scenario ID. This local CommerceCare SC-006 definition tests refund-verification behavior and shows its goal, class, category, three acceptance criteria, and execution history. Review the criteria themselves, not just the scenario title.

Hosted Web UI: Find the Scenario to Review

Open project → agent → Scenarios. Filter by feature, class, result, or category, then click the scenario ID for its definition. The sample has one passing scenario and one that never ran; generating a scenario does not establish a result.
