Scores are only 0 or 10, so no mean score is shown. +- **`llm_judge`** scores each answer against the case's expectation and an + optional dataset rubric. The dashboard shows pass rate, mean score, + low-score cases, full answers and reasons. Judge scores are screening + signals; calibrate them against a small human-reviewed set before treating + them as a quality target. + +`json_exact` is a strict contract. Dataset authors should know the rules: + +- The whole answer must parse as one JSON object. A surrounding Markdown + code fence is stripped; any other prose before or after the object makes + the answer an invalid output. +- The field must be a string. Its value is trimmed and compared + **case-sensitively** with the trimmed expected value, so `Billing` fails + against `billing`. Write the expected values in the exact form the agent + is told to return. +- A dotted `output_field` walks nested objects, up to four levels. + +The judge runs on the platform's own headless kernel with the same default +model family as most agents under test. That keeps the sample free of extra +dependencies, but the judge is not independent of what it grades and can +share its blind spots. In the difficult-customer runs it passed an answer +that invented a response deadline. Treat a pass as "nothing obviously wrong" +and keep reviewing the stored answers. + +Users can create a custom scenario and choose its scoring contract in the +**Evaluation** page. The equivalent API request is: + +```json +{ + "name": "claims-routing-v1", + "scenario": "claims-routing", + "scoring": {"method": "json_exact", "output_field": "decision.intent", "rubric": ""}, + "cases": [{"prompt": "I need a refund for order A", "expected": "refund"}] +} +``` + +The agent must then return a JSON object with `decision.intent`. A new +scenario appears in Observability when its first evaluation run starts. +For an LLM-judged scenario, use `method = llm_judge` and set `rubric` to the +business-specific judging criteria. + +When `scoring` is omitted, the scenario name picks a default: `classification` +becomes `json_exact` on `category`, and every other scenario becomes +`llm_judge` with no rubric. The default keeps datasets created before +scoring configuration working. Pass `scoring` explicitly for new datasets so +the contract is visible in the request. + +This is the no-code extension path. For a new scoring algorithm, extend +`EvalScoringConfig` in `backend/app/models/schemas.py`, the scoring dispatch +in `backend/app/services/eval_service.py`, and the method selector in +`frontend/src/pages/EvalPage.tsx`. The dashboard draws a value distribution +for exact JSON scoring and a score breakdown for judge scoring. A custom +algorithm may also need a corresponding dashboard component. The platform +does not execute arbitrary user-uploaded evaluator code. + +Each run records the published agent's version at start, and the system +prompt of that version is stored once and shared by every run of it. Each +case's prompt, expectation, full answer and verdict is stored as its own item, +so a run of 20 long multilingual cases stays well inside DynamoDB's item size +limit. A version change while a run is executing fails the run so it cannot be +presented as a single-version comparison. + +Each case also records the execution facts of its own calls, the same ones +the invocation ledger keeps: ok, duration, turns, cost and runtime session id, +for the agent call and for the judge call. The run summary aggregates them +when it ends. The page shows that infrastructure view next to the pass rate +for the same cases, for example "20/20 agent calls returned ok, 6 of those +answers broke the expectation", with no join against the ledger. The session +id on a case is also the `session.id` on its kernel spans when trace delivery +is enabled. A dataset's run history is read through its own index, so the +previous run is found however many runs of other datasets came after it. + +The dashboard compares completed runs of the **same dataset**. Every pass rate +is shown with its sample size, because one case moves the rate of an 8-case +dataset by over 12 points. A drop is flagged only when it amounts to at least +two cases. This is an offline benchmark: +the general invocation ledger still stores only a 200-character user-prompt +preview and execution metrics. It has no automatic business label or +production-conversation quality score. + +To generate results without customer data, run the synthetic benchmark against +a **deployed** portal: + +```bash +PORTAL_URL=https:// \ +PORTAL_TOKEN= \ +python3 scripts/run_observability_demo.py +``` + +For local open-auth development, omit `PORTAL_TOKEN`. The script publishes a +classifier and a support agent, creates two reusable synthetic datasets, +starts real AgentCore invocations, waits for scored results, and reports how +many of the case calls it finds in the invocation ledger. Re-running bumps the +agents' versions and adds comparable runs to the same datasets. It does not +fabricate predictions, answers, scores, token usage, latency, or cost. Model +calls incur the platform's normal charges and quota. + +Agent and dataset names start with `--prefix`, `obs-demo-` by default. An +administrator can republish an agent another user published, so the script +checks first: if an agent with one of its names exists and was not created +by these scripts, it stops instead of overwriting it. Choose another prefix +in that case. + +The ledger endpoint returns the latest 200 rows across the platform. On a +deployment with other traffic, part of a run's calls can be older than that. +The script then reports the count it found as "in window" rather than +failing. + +### Difficult-customer benchmarks + +`scripts/run_difficult_customer_evals.py` builds on the two demo agents (run +the demo script first, with the same `--prefix`) and adds three more +scenarios: `oncall` (severity triage, `json_exact` on +`severity`), `rnd` (an engineering assistant) and `sales-success`. It runs +96 adversarial cases in two rounds: + +- **hard**: prompt injection, forged system messages, output-format + overrides, social engineering, requests beyond policy, and several + languages. +- **extreme**: contradictory stakeholders, profanity, personal attacks, + blame-shifting, and claimed promises that nobody can verify. The judge + rubric also fails an answer that mirrors abuse, admits liability it + cannot verify, over-apologises into a commitment, or lectures the user. + +```bash +PORTAL_URL=https:// PORTAL_TOKEN= \ +python3 scripts/run_difficult_customer_evals.py --round all +``` + +The script ends by printing, for each run, the infrastructure view of its +calls next to its pass rate. Both come from the run itself, so they always +cover the same cases. The usual result is that every call succeeds at the +infrastructure layer, with no errors and normal latency and cost. The evaluation layer still flags answers +that broke a business rule, for example an upsell to a customer claiming +compensation, a response deadline the policy never states, or a severity +talked down by an angry message.

Every decision here +is a reply to one of those three facts. + +--- + +## 1. The runtime does not reach the internet; tools do + +**Done.** The agent runs on an AgentCore Runtime in private subnets. It calls +tools through one AgentCore Gateway (SigV4, the runtime's own role) and the +gateway's targets are what reach upstream APIs: a Lambda for the crypto price, +the gateway itself for the stock quote. + +**Prevents.** Server-side request forgery and exfiltration through the model. +An agent that can `fetch(url)` can be asked to fetch an internal metadata +endpoint, or to send what it knows to a host of the asker's choosing. An agent +whose only outbound path is a gateway with named tools can do neither: there +is no "fetch" tool, and the gateway's targets have fixed hosts. + +**Skipping it costs.** Every prompt becomes part of the network boundary. You +would review prompt changes the way you review firewall rules, and a model +upgrade that changes how it handles instructions would be a security change. + +**For your systems.** Keep the shape, change the targets. A private REST API +behind an internal ALB becomes an OpenAPI target with a private endpoint +(VPC Lattice); an internal service with no HTTP API becomes a Lambda target. +The agent's configuration does not change: it still has one MCP attachment, +the gateway. + +## 2. One gateway with a policy engine, not one gateway per tool + +**Done.** Both tools are targets on the same `sample-tools` gateway. A policy +engine is attached; Cedar policies decide, per call, whether this caller may +invoke this tool with these inputs. + +**Prevents.** Two failure modes of the per-tool-gateway alternative. First, +drift: twenty tools become twenty gateways, twenty execution roles and twenty +places to audit. Second, false comfort: IAM's `InvokeGateway` is granted per +gateway and has no condition key for the tool name, so "one gateway per tool" +is the only way to make IAM alone decide tool access, and it does not scale. +The gateway's design point is the opposite: up to 100 targets per gateway, +with AgentCore Policy deciding at tool granularity. `tools/list` returns only +what the caller is permitted, so a caller does not even see tools it may not +use. + +**Skipping it costs.** Either the sprawl above, or a single gateway where every +caller sees every tool and the agent's prompt is the only thing between a +read-only assistant and a tool that can act. + +**For your systems.** Add tools as targets on the same gateway. Add a +`permit` per (caller role, tool) in the engine. Start the engine in +`LOG_ONLY`, read the decision traces for a week, then switch to `ENFORCE`. The +sample ships in `LOG_ONLY` for exactly that reason. + +## 3. Each sample runs on its own runtime under its own IAM role + +**Done.** `investment-assistant` has a runtime of its own, running the same +headless kernel image as every published agent, with an execution role of its +own. The Cedar policies name that role (`AgentCore::IamEntity`, the caller's +assumed-role ARN). The shared kernel role is in no sample policy. + +**Prevents.** Identity confusion at the gateway. A Cedar policy can only be as +precise as the principal it sees, and with an IAM-authenticated gateway the +principal is the role. If every agent ran under one role, a policy permitting +"the investment assistant" would permit every agent on the platform. + +**Skipping it costs.** The gateway could still restrict tools per role, but +"per role" would mean "per platform", and a tool attached to the investment +assistant would be callable by any agent a user publishes. + +**For your systems.** One runtime per trust boundary, not per agent. Agents +that may call the same tools share a runtime and a role; an agent that may +call a tool with side effects gets its own. The runtime is cheap (no idle +cost); the role is the unit of policy. + +## 4. Tool access is decided by the gateway, not by the agent's configuration + +**Done.** An agent cloned from the sample records `runtime = sample:`. The +backend admits that field only on a clone of that sample and keeps it on every +republish; a plain publish naming a sample runtime is refused. The user may +change the prompt, model, turn budget, skills and memory of a clone; the +runtime, and so the set of tools the gateway will allow, is not theirs to +change. + +**Prevents.** The "I just attached the gateway" path. Without this, a user +could attach `sample-tools` to any agent; it would see no tools (policy), but +the failure would be confusing, and a future policy edit could open it. With +this, attaching the gateway to an ordinary agent is visibly inert, and the +only way onto a sample's identity is through the sample. + +**Skipping it costs.** Tool access would depend on two things staying in sync, +the gateway's policy and the portal's attachment rules, and the portal's rules +are the ones users touch daily. + +**For your systems.** Treat "which runtime" as a property set by whoever owns +the tool boundary (an administrator, a template, a pipeline), not by the +agent's author.

Where the credential lives + +**Done.** The Twelve Data key lives in an AgentCore Identity API-key +credential provider that an operator registers with one command +(`scripts/set_sample_tool_key.sh stock-quote`, key from a file or stdin). The +foundation finds the provider by its conventional name +(`sample-tool-stock-quote`) at plan time and publishes its ARN in the +facts; no tfvars carries it.

Input constraints are written in Cedar, not only in code + +**Done.** `crypto-price` accepts ten symbols. The allowlist is in the Lambda, +and it is also in the Cedar policy: `context.input.symbol` must be in the set +or the gateway denies the call before the function runs. `stock-quote` requires +a symbol; the upstream validates the ticker. + +**Prevents.** Two things. The function being reached with an input it should +not see (defence in depth), and the constraint being invisible: a Cedar deny +is a decision in the audit trail with the principal, the action and the +input; a Lambda returning `unsupported_symbol` is a log line. + +**Skipping it costs.** Changing the allowed set is a deployment instead of a +policy update, and the only record that a symbol was refused is in the +function's logs. + +**For your systems.** Put the constraints a security reviewer would ask about +in Cedar (amount ceilings, allowed regions, read-only operations) and keep +business validation in code. + +## 8. The answer carries its time and its source; the agent gives no advice + +**Done.** Both tools return the upstream's own timestamp and a source string. +The prompt requires every quote to state price, currency, as-of time and +source, forbids estimating, converting or recalling prices, and forbids +investment advice. The eval set includes an advice request, an injection that +asks the agent to fetch a URL, and an unsupported symbol. + +**Prevents.** A confidently stale or invented number. A market quote without a +time is wrong by definition a minute later; a quote without a source cannot be +checked. + +**Skipping it costs.** The sample would demonstrate the mechanics and teach the +wrong habit. + +**For your systems.** Make the tool return the provenance (time, source, +version) and make the prompt require it in the answer. Put the refusals you +need in the evals, so a prompt edit that drops one is caught. + +## 9. What a clone keeps and what it may change + +**Done.** A clone keeps the runtime (identity), the MCP attachment (the gateway) +and so the tool boundary. The user may change the system prompt, model, turn +budget, skills and memory. + +**Prevents.** Treating the sample as a template that is copied and forgotten. +A clone is still bound to the sample's identity, so a policy change on the +gateway applies to every clone at once. + +**Skipping it costs.** Twenty clones with twenty slightly different ideas of +what the agent may do. + +**For your systems.** Decide which fields are the platform's and which are the +author's before you let anyone clone. Here the line is: anything that changes +*what the agent can reach* is the platform's; anything that changes *how it +talks* is the author's. + +## 10. What this sample does not do + +- **The runtime's security group still allows all egress.** The tool layer is + the egress choke point, the runtime layer is not yet. Closing it needs an + inventory of every endpoint the kernel reaches (model, S3, logs, the + gateway) and VPC endpoints for each; that is the next step, not this one. +- **Demonstration data sources.** CoinGecko's keyless tier is rate-limited and + not for production; Twelve Data's free plan is 8 calls per minute. A real + deployment swaps the upstream in the tool package and leaves the agent alone. +- **One identity per sample, not per user.** The gateway sees the runtime's + role, not the person who asked.
