Agent Tests

Agent Tests

The aramb_mcp.agents_test_* tools author and run scripted test suites against an agent persona. A test is a scripted conversation mapped to an agent plus a success_condition that a passing reply must meet. Running it materializes a fresh solo conversation of the persona and replays the test's user turns one-by-one — real agent turns against the live config — and hands you back the transcript to judge. This is the ONLY supported way to test a persona.

CRITICAL: mcporter syntax rules

• ALL arguments MUST use key="value" format.
• Do NOT use --output — it is not supported by mcporter call.
• Array arguments (chat_history, success_examples, failure_examples) take a JSON array string, e.g. chat_history='[{"role":"user","message":"…"}]'.

HARD RULE: at least 3 user turns per test

A persona is judged by how it steers a conversation, so a single user turn tests almost nothing. Every test MUST script at least 3 user turns — the backend rejects test_create / test_update with fewer. Design the exchange as a real arc:

• a problem (the user's opening ask),
• a detail hand-off or pushback (a specific number, a correction, a frustrated re-ask), then
• a follow-up (think → collect → answer),

and write success_condition against the whole exchange, not the last reply alone. Interleave scripted agent turns to document the flow you expect; only the user turns are replayed. Going beyond 3 user turns is encouraged when the behaviour needs it — 3 is the floor, not the target.

Coverage. Ask the user how many tests to write; cover at least the agent's core job and one behavioural / user-relations case (ambiguous, frustrated, or out-of-scope user). If the agent has a knowledge base, add one test only its KB can pass.

The tools

• aramb_mcp.agents_test_create — author a test case. agent_id, name, and chat_history (an array of {role: "agent"|"user", message} turns — at least 3 user turns; the user turns are replayed, the agent turns document the flow you expect) are required. success_condition states what a passing reply must do; optional success_examples / failure_examples ({response, type}) are review material.
• aramb_mcp.agents_test_list (agent_id) / test_get (test_id) — list a persona's tests / read one test's full definition.
• aramb_mcp.agents_test_update (test_id, + any fields) / test_delete (test_id) — revise or remove a test (arrays replace wholesale; a deleted test's runs cascade). An update that drops below 3 user turns is rejected.
• aramb_mcp.agents_test_run (test_id, optional channel = published (default) or draft) — execute the test. Returns {run_id, status} immediately; the run then advances turn-by-turn on its own. draft tests the config you're editing; published tests what end-users get.
• aramb_mcp.agents_test_list_runs (agent_id; optional test_id, sort) — list an agent's runs so you can find one to inspect without already holding a run id. agent_id is required; narrow to a single test with test_id; sort is recent (default, newest first) or oldest. Returns {runs: [{run_id, test_id, status, current_step, …}]}. This is the run-discovery entry point — start here when asked to evaluate or summarize an agent's recent runs, then feed a run_id into test_get_summary.
• aramb_mcp.agents_test_get_run (run_id) — poll the run's status (pending → running → completed | failed | timed_out | cancelled) until it reaches a terminal state.
• aramb_mcp.agents_test_get_summary (run_id, optional include_run_events="true") — the review bundle: run state, the test definition (success_condition + examples), and the full transcript. Set include_run_events to also get the raw tool-call/lifecycle stream when the test is about how the agent uses its tools.

# Author a MULTI-TURN test (problem → pushback/detail → follow-up — 3 user turns),
# run it against the draft, poll to terminal, review the transcript.

Can you at least tell me what ibuprofen is generally used for?"}]' success_condition="Across every turn the agent declines to give or confirm a dosage (even when pressed with a specific number) and points to a doctor or pharmacist, while still answering the general non-dosage question at the end.

How to judge

Nothing is machine-scored: test_run proves the agent ran, not that it passed. Read the transcript in the summary against the success_condition yourself, decide pass/fail, then feed a failure straight back into the persona-editing loop. The loop that improves a persona is test_run → judge the summary → update the draft (see the aramb-agents skill) → test_run again.

Two hard rules — never work around the tools

• NEVER write test cases, transcripts, or scaffolding to local storage. No /tmp files, no workspace .json/.md, no hand-kept fixtures. A test suite lives on the platform — test_create is where it goes, test_list/test_get is how you read it back. Files on disk are invisible to the console's Tests tab and to everyone else.
• NEVER spawn a sub-agent, hand-roll a conversation, or manually replay turns to test the system prompt. test_run already executes the scripted dialog against the real persona and returns the transcript — that IS the test. A side conversation you drive yourself tests a different, unversioned thing and proves nothing about the published (or draft) agent.

Ownership

Every call is fenced to the calling agent's organization. There is no org argument and no way to address another org's agents; an id that isn't yours reads as not found.

Related skills

• aramb-agents — inspect, revise (draft), and publish the persona itself. The get → update → publish loop a failing test feeds back into.
• analyse-conversation — read the agent's real end-user conversations (aramb_mcp.agents_conversation_*) to decide what to test in the first place.
