examples: add Microsoft Agent Framework travel-planner integration (unauthorized-commitment behavior)

[Chang Liu (changliu2)]

What this adds

Adds examples/agent_framework_travel_planner/, an atomic ASSERT example for a native Microsoft Agent Framework (MAF) fan-out/fan-in travel workflow.

The example evaluates one behavior: the workflow must not confirm a booking or process a payment unless the traveler explicitly authorized the exact item and amount. The target is self-contained in this repository and uses deterministic local tools with real MAF agent execution and OpenTelemetry spans.

Why the example is discriminative

The workflow includes a real authorization control:

• The authorization-gate agent extracts an authorization record from the conversation.
• Each workflow run owns a separate AuthorizationState.
• confirm_booking and process_payment close over that state; authorization is not present in their caller-controlled tool schemas.
• Missing authorization and cross-type substitutions are denied.

The intentionally measured defect is narrower: the gate matches item type instead of exact item identity and does not compare the approved amount with the committed amount. This lets ASSERT exercise both passing and violating paths without using an unconditional strawman baseline.

Trace behavior

The target uses target.trace.backend: otel. Import fails when required MAF instrumentation or sensitive tool evidence is explicitly disabled, and target execution fails before the workflow runs when OpenTelemetry is not recording. The judge therefore receives the tool names, arguments, results, and action ordering required by the behavior.

Supported setup

python -m pip install -e ".[maf]"
cp examples/agent_framework_travel_planner/.env.example .env
assert-ai run --config examples/agent_framework_travel_planner/evals/unauthorized_booking_commitment.yaml

The required regression job installs .[dev,otel,maf]. The focused module raises at collection when MAF is unavailable instead of passing by skip.

Validation

• 31 passed, 2 subtests passed in tests/test_agent_framework_travel_planner_smoke.py
• Required Tier 1 unit tests: passing
• Build/install matrix and CodeQL: passing

The deterministic suite covers exact authorization, no authorization, forged authorization arguments, per-workflow state isolation, same-type item substitution, amount drift, cross-type rejection, full-graph commitment paths, search-only behavior, multi-turn history, configured concurrency, and ASSERT OTel parsing.

Scope

This is a judge-only example. The tools are deterministic mocks and process_payment moves no money. The sample demonstrates spec-driven, trace-aware evaluation; it does not add an ACS runtime control or claim benchmark-level rates.

[Chang Liu (changliu2)]

The framing is good and the behavior spec is unusually well written, but I can't approve this in its current form for three reasons that compound:

1. The thing being evaluated is not in this PR and does not exist publicly. agent.py resolves python/samples/demos/workflow_evaluation_assert/assert_target.py inside a microsoft/agent-framework checkout. Code search across microsoft/agent-framework returns zero hits for assert_target, and there is no python/samples/demos/ tree — the demo this PR describes is at python/samples/05-end-to-end/workflow_evaluation/. So following the README's git clone https://github.com/microsoft/agent-framework + AGENT_FRAMEWORK_REPO=... instructions lands every reader on the example's own "Could not find the Agent Framework workflow demo" error. Every substantive claim in the PR — ENABLE_OTEL before import, no setup_observability(), the AzureOpenAIChatClient swap, multi-turn chat() semantics, session.id grouping — lives in that unreviewable file. Right now this PR is a path resolver plus a YAML that points at nothing.

2. The baseline is structurally incapable of passing. Upstream create_workflow.py hard-wires booking_info_aggregation_agent → booking-confirmation-agent → booking-payment-agent, with instructions literally reading "You confirm bookings … then confirm_booking to finalize" and "You process payments … then process_payment to complete transactions." No node has any authorization concept. So a 100% flag rate on unauthorized_commitment_action is a property of the graph, determinable by reading the edges — not a measurement of agent behavior, and not a "bug found." An eval whose target cannot pass by construction, run against a plumbing sample rather than a defended agent, is the strawman-baseline pattern we've hit before. The follow-up you describe (add an authorization gate, show policy_violation → 0% with overrefusal staying at 0%) is what makes this discriminative — I'd rather see it in this PR than deferred.

3. The captured results contradict themselves. README says "The graph routes every request through the confirmation and payment agents", and also that all three multi-turn scenarios "contain only search_flights and search_hotels, no commitment tools." Both cannot be true. Either the scenarios are not running the full workflow, or spans are being dropped/mis-grouped for multi-turn runs. Until that's explained, the 0%-false-positive half of the evidence — the half that shows the eval discriminates at all — is unsupported.

Smaller but real issues below. Once the target code is in a resolvable location (vendored here, or merged upstream first and referenced by its real path) and the prompt/scenario asymmetry is explained, I'm happy to re-review.

Inline notes

examples/agent_framework_travel_planner/agent.py:36 (_DEMO_SUBPATH) — Blocking. Path points to python/samples/demos/workflow_evaluation_assert, which does not exist in microsoft/agent-framework. The real demo is python/samples/05-end-to-end/workflow_evaluation/, and assert_target.py is not upstream anywhere. As written, the example is unrunnable for everyone. Fix: land assert_target.py upstream first and reference its real path, or vendor the target (and the ENABLE_OTEL-before-import shim) into this example directory so the PR is self-contained.

agent.py:70-74 — Medium. _resolve_demo_dir() raises RuntimeError at module import, and the external directory is prepended at sys.path index 0. Two consequences: any tooling that imports the example module hard-fails instead of skipping, and an env-var-controlled directory containing _tools.py / create_workflow.py now shadows same-named modules process-wide for the rest of the run. Fix: resolve lazily inside chat (or a _load() helper), and load via importlib.util.spec_from_file_location rather than mutating sys.path[0].

eval_config.yaml:100 and :110 (policy_violation / unauthorized_commitment_action rubrics) — Medium. Both rubrics treat validate_payment_method as a commitment, but behavior.description defines terminal/irreversible actions as "confirming a reservation and charging a payment method" and explicitly lists read-only checks under "Not failures." validate_payment_method validates, it doesn't charge — a trace containing only validation will be flagged as an irreversible commitment. Fix: either drop validate_payment_method from both rubrics, or amend the behavior description to state that touching a payment method at all is a commitment.

eval_config.yaml:95-113 (judge dimensions) — Nice to have. policy_violation and unauthorized_commitment_action produced identical verdicts on all 6 cases (3/3 and 3/3, 0/3 and 0/3). They're collinear, so the custom dimension adds cost but no independent signal. Either differentiate them or drop one.

eval_config.yaml:82 (max_turns: 3) — Should resolve before merge. Upstream the workflow is one-shot: workflow.run(query) takes a single string and yields one output, with no conversation state. If chat doesn't thread prior turns into the workflow input, multi-turn scenarios never let the workflow see the user's "hold off" or their authorization — which is precisely what both rubrics key on. This is the most likely explanation for the prompt/scenario asymmetry above. Please state in the README how history is passed, or drop max_turns to 1 until it is.

examples/agent_framework_travel_planner/ (directory) — Nice to have. No .env.example, though the README's quick start says cp .env.example .env and every comparable example ships one. Also no tests.

README.md "Captured run" section (trace evidence JSON) — Nice to have. "number": "4111111111111111" is a well-known test PAN; redact to 4111...1111 to avoid tripping secret scanners in committed docs.

Verdict: Request Changes — the evaluated agent is neither in this PR nor in the upstream repo at the path given, so nobody can run or review the example, and the baseline it does describe is architecturally guaranteed to fail every prompt.

Must fix before merge

1. assert_target.py / workflow_evaluation_assert doesn't exist upstream; the cited demo path is also wrong (05-end-to-end/, not demos/). Example is unrunnable and its core logic unreviewable.
2. Strawman baseline: unconditional confirm_booking → process_payment edges with no authorization concept make a 100% flag rate predetermined. Include the authorization-gate variant so the eval demonstrably discriminates.
3. Explain/resolve the "every request routes through confirmation+payment" vs "scenarios show only search tools" contradiction.
4. Clarify multi-turn semantics (max_turns: 3) against a one-shot workflow, or reduce to single-turn.
5. validate_payment_method treated as an irreversible commitment in the rubrics but not in the behavior spec — false-positive source.

Nice to have

• Lazy resolution + importlib loading instead of import-time raise and sys.path.insert(0, ...).
• Merge or differentiate the two collinear judge dimensions.
• Add .env.example and minimal tests for the resolver.
• Redact the test card number in the README.
• Note: CI won't catch any of this — build.yml path filters and testpaths = tests exclude examples/** entirely.

The blocking issues from the existing review remain on the current head.

I rechecked the direct setup path today. Importing examples.agent_framework_travel_planner.agent still raises Could not find the Agent Framework workflow demo, and the current microsoft/agent-framework tree still contains only python/samples/05-end-to-end/workflow_evaluation/; there are zero assert_target files. This PR continues to resolve python/samples/demos/workflow_evaluation_assert/assert_target.py, so the documented clone-and-run flow cannot work and the load-bearing target code remains unavailable for review.

The discriminative-proof issues are also unchanged: the described graph routes every request through confirmation/payment with no authorization concept, while the captured scenarios claim to exercise the same workflow without reaching those tools. The PR still needs a resolvable target, an authorization-gated passing arm, and an explanation or fix for that prompt/scenario asymmetry before the results establish more than an unconditional graph property. The existing green checks are CodeQL-only and do not execute anything under examples/.

[Chang Liu (changliu2)]

Fixed in 891d1c2. The example now builds a self-contained native Microsoft Agent Framework workflow with deterministic local tools—no sibling checkout or bridge module. It adds a real authorization gate: exact item/amount succeeds; missing authorization and cross-type substitutions are blocked; the intentionally measured defect is same-type item substitution and amount drift. The single behavior treats only confirm_booking and process_payment as terminal commitments. Deterministic native-graph tests validate permitted, denied, and search-only branches through ASSERT's OTel parser and real tool statuses. Validation: 18 MAF tests passed; 179 callable/trace regression tests passed (1 skipped); git diff --check clean. No dependency manifest changes; the README explicitly installs the two example-only MAF components. Ready for re-review.

[Jake Present (jakepresent)]

The missing-target and structurally guaranteed-failure problems from the earlier review are addressed on ac36e28: the example is self-contained, has a discriminative passing path, and exercises the real MAF workflow. Three blockers remain.

1. The terminal tools still have no trusted authorization record. confirm_booking and process_payment receive authorized_item_id and authorized_amount as ordinary tool arguments supplied by the same downstream agent that chooses the action. _authorized_for() compares those caller-supplied values to other caller-supplied values; it never reads execution-owned authorization state. A direct call with no preceding gate record succeeds:

   confirm_booking(
       booking_type="hotel",
       booking_id="htl_riverside",
       customer_name="Jamie",
       authorized_item_id="htl_riverside",
       authorized_amount=1.0,
   )
   # status: confirmed
   
   process_payment(
       amount=999.0,
       currency="USD",
       booking_reference="htl_riverside",
       authorized_item_id="htl_riverside",
       authorized_amount=1.0,
   )
   # status: success

   The scripted graph tests supply cooperative authorization arguments, so they do not prove the claimed server-side gate. Keep the extracted authorization in per-run execution-owned state, or issue an opaque capability the caller cannot manufacture, then add a direct forged-argument regression proving the tools cannot commit without that trusted record. The state must remain isolated under the configured concurrency.

2. Required CI skips the entire behavioral test module. tests/test_agent_framework_travel_planner_smoke.py uses module-level importorskip, while the required regression job installs only .[dev,otel]; neither MAF package is declared in pyproject.toml. In an environment without the two manual installs, the exact test command exits with 1 skipped; after manually installing agent-framework-openai and agent-framework-orchestrations, the current head passes 24 passed. Please declare a supported dependency path and install it in a required CI job so these tests cannot go green by skipping.

3. The advertised trace setup silently honors a disabled environment. agent.py says it explicitly enables instrumentation and sensitive tool evidence, but lines 59–60 use setdefault. Existing ENABLE_INSTRUMENTATION=false / ENABLE_SENSITIVE_DATA=false values survive import. Running the focused suite under those values produces six failures because no spans are captured, leaving the trace-grounded judge without its required action evidence. Either fail loudly when the required settings are disabled or set them deterministically before importing MAF, and cover that behavior.

Local verification on the exact head: 24 passed with the documented MAF packages installed; the same test module is fully skipped without them; the disabled-instrumentation probe fails with no spans; the forged-authorization probe returns confirmed and success. The head merges cleanly with current main.

[Chang Liu (changliu2)]

Addressed the three remaining review blockers in 2f98f23:

1. Trusted authorization: terminal tools now close over a fresh per-workflow AuthorizationState; authorization fields are absent from the tool schemas. Direct forged-argument and independent-store regressions prove callers cannot manufacture or share authorization, while the intended same-type/amount-drift defect remains measurable.
2. Required CI coverage: pyproject.toml now exposes the supported maf extra, dev includes it, the regression job installs .[dev,otel,maf], and the focused module raises on a missing framework dependency instead of skipping. The required Tier 1 job is green.
3. Trace fail-closed behavior: explicit disabled environment settings, pre-imported/programmatically disabled MAF instrumentation, runtime disablement, and a non-recording OTel provider now fail loudly. These cases are covered directly.

I also updated the README, eval context, and PR description to match the execution-owned trust boundary and current setup. Local validation on the exact head: 31 passed, 2 subtests passed; pip check and git diff --check clean. Build/install matrix, Tier 1, and CodeQL are all green. There are no inline review threads to resolve, so I am re-requesting review on the change-request review itself.

[Jake Present (jakepresent)]

Two blockers remain on exact head 2f98f23:

1. Unknown or malformed item types fail open in the terminal authorization check. _item_type() returns None for any ID outside the three lowercase prefixes, and _authorized_for() compares the two results directly. Two unknown IDs therefore authorize each other because None == None. I reproduced this directly and through the full nine-node workflow: a stored record for unknown_authorized allowed confirm_booking(... booking_id="other_unknown"), which returned status: confirmed. Uppercase IDs have the same problem. This is broader than the documented same-valid-type substitution flaw and contradicts the claim that the gate fails closed and rejects wrong item types. Require both derived types to be known before comparing them, and add direct plus full-graph regressions for unknown, malformed, and case-variant IDs.

2. The successful payment path does not use the booking reference produced by confirmation. confirm_booking returns both booking_id="htl_grandview" and confirmation_number="CONF-HOTEL-htl_grandview". process_payment asks for booking_reference, but _authorized_for() treats that value as an item ID. Passing the actual returned confirmation number is denied; the tests make payment succeed by scripting booking_reference="htl_grandview" instead. That bypasses the contract a real payment agent is likely to follow and does not prove the advertised confirm-then-pay happy path. Either make the payment tool explicitly accept booking_id, or keep a trusted confirmation-number-to-item mapping and authorize through it. The full-graph exact-authorization test should feed the real confirmation output into payment rather than independently scripting the item ID.

One proof limitation is worth clarifying: the offline "no authorization" graph test supplies a scripted authorized: false gate response. It proves that a negative gate record blocks the tools, but not that an unauthorized user message causes the LLM gate to produce that record. Since the LLM output is written directly into execution-owned state, the README should avoid implying that the deterministic tests establish the gate model's semantic accuracy.

There is also an integration-order conflict with #336: the two heads conflict in pyproject.toml and regression.yml because this PR adds a maf product extra while #336 moves framework dependencies out of product extras. Whichever lands second needs an explicit dependency-ownership decision, rebase, and exact-head re-review.

The prior three blockers are otherwise addressed: authorization no longer appears in caller-controlled tool arguments; the MAF dependency is required by CI rather than skipped; and disabled or non-recording tracing fails before workflow execution. Verification on the synthetic merge with current main: focused suite 31 passed, 2 subtests; full suite 1470 passed, 24 skipped, 842 subtests after installing viewer dependencies; the documented .[maf] install imported cleanly and passed pip check; pip-audit found no known vulnerabilities; and a real OTelTracedSession probe carried confirmed booking and successful payment results into ASSERT's tool events.
