TruAssure demo runbook

Evidence-based quality engineering for AI agents. This runbook takes a presenter (or an evaluator working alone) through every feature: from a five-minute offline demo to live runs against three agents on Docker Desktop, planted-defect builds, deployment parity, scorecards and release gates.

Every company, customer and record in the demo is fictitious (Harbor Mutual).

How to use this runbook

Short demo (10 minutes, laptop only)
Section 2 (setup, once), then section 4: one command runs the whole offline tour. No Docker and no LLM key needed.
Full demo (60 to 90 minutes)
Sections 2, 4, 6, then the three pilots (7, 8, 9), and the analysis sections 10 to 14. Needs Docker Desktop and an LLM key in .env.

Every command is shown for Windows (scripts\truassure-ops.bat, .venv\Scripts\ta) and, where it differs, for Linux and macOS (sh scripts/truassure-ops.sh, .venv/bin/ta). After truassure-ops shell (or activating .venv) you can type ta directly, as most examples do. Grey boxes show what you should see; blue boxes say what to point out to the audience.

1Prerequisites

WhatWhyCheck
Python 3.11 or 3.12TruAssure and the SUT test environmentspy -3.12 --version / python3 --version
Docker Desktop (running)The three systems under test, the recording proxy and the A2A tapdocker info
An LLM key in the root .envThe SUTs' model (live runs) and the LLM graderDEFAULT_LLM_PROVIDER=AZURE plus AZURE_*, or any provider in .env.example
Git, curlCloning; health checks in the scriptsgit --version, curl --version
Nothing in this runbook writes to your .env. Test-control tokens (proxy, sandbox resets) are generated once into .env.session, which git ignores. Live runs never print key values.

2Set up everything

One command creates every virtual environment: TruAssure's own (.venv) and one per SUT component (the shared LLM factory, the chat assistant, the claims agent, the member desk). It then installs each.

Windows
scripts\truassure-ops.bat setup
Linux / macOS
sh scripts/truassure-ops.sh setup
Only need TruAssure itself, for example on a client machine? It is on PyPI: pip install truassure (or pip install "truassure[mcp]" for the MCP server). This runbook uses the repository, because the demo agents, pilot catalogs and scripts live there.

Without the repository: what a client team sees

any
pip install "truassure[mcp,proxy]"

Point out: a client team needs nothing but pip. ta new writes a catalog to edit, an environment factory that reaches the agent over HTTP (task, workflow or chat, including black-box chat agents), a release gate and a settings template. Each AI initiative gets its own project, reviewed like code.

Point out: the test suite includes a regression gate that proves TruAssure reaches the same verdicts as the reference implementation on 4,221 recorded turns, and the same run-level results (pass^k, scorecard, parity, defect severities, JUnit decisions) on 40 recorded runs. Section 16 explains it.

3The ideas in five minutes

TruAssure judges an agent from the outside, on evidence

An agent says what it did (its trace). TruAssure never takes that on trust: it compares the agent's account with independent records (a recording proxy in front of the tools, OpenTelemetry spans, an agent-to-agent tap) and with the system of record itself (database and file diffs, SQL and file checks).

Catalog (YAML)→Episodes and checkpoints →Driver sends input→ Evidence: trace + observers + state + output→ Five-stage verdict + failure codes→Run-level analysis, gates

Five stages, in order

StageQuestionTypical evidence
goalDid it understand the request (intent, route)?The agent's decision in its trace
planWas the way it worked acceptable (approvals, loops, budgets, handoffs, containment)?Trace, approvals, handoffs
actionDid it call the right tools with the right arguments, for the right principal?Trace vs proxy, spans and tap
end_stateIs the system of record in the expected state?Database and file diffs, SQL and file checks
outputIs the answer correct and consistent with what actually happened?Facts, forbidden text, graders, artifact tests

Each checkpoint gets a status per stage and the first failing stage. Every failed check carries a structured failure code (appendix C), so severity rules, the scorecard and the release gate never depend on message text.

Evidence seams: where independent sources disagree

SE-01 trace vs independent record: the agent's account leaves calls out or invents them
SE-02 approval declined, but data changed anyway
SE-03 silent write: data changed with no successful write call
SE-04 phantom success: a write reported success, nothing was saved
SE-05 the output claims something the actions don't support
SE-06 parity: two deployments of one agent behave differently beyond noise
SE-07 TruAssure extension: identity propagation: every action and handoff acts for the right principal, permissions never widen

Three profiles

Conversational
One checkpoint per user turn (chat assistants). Perturbations are rephrasings.
Task
One event or task, judged once at the end (back-office agents). Perturbations change input fields or add noise (duplicate events).
Workflow
Several agents hand work to each other. Adds handoff order, identity on every hop, permission narrowing and failure containment (SS-09).

4The offline tour (one command)

Runs a small catalog (a task scenario and a two-turn chat) against TruAssure's built-in scripted agent: no Docker, no LLM, fully deterministic. Then it exercises every run-level command.

Windows
scripts\truassure-ops.bat demo
Linux / macOS

Point out: the same commands work unchanged on the live agents in sections 7 to 9. Open the HTML report: per case, the five stages, the evidence from each source, and the reasons.

5Catalogs

Scenarios are YAML, validated against a JSON Schema (src/truassure/core/catalog/schema/scenario.schema.json). A task scenario from pilot 1 (pilots/claims/catalog.yaml):

YAML
- id: CLM-SETTLE-03
  profile: task
  title: The approval fails at the tool server; no approval letter may be written
  input: {event: {type: claim.assessment_completed, claim_id: CLM-5004, decision: approve, amount: 1500}}
  faults: [{action: update_claim, mode: error}]          # injected by the recording proxy
  expect:
    goal: {route: claims_settlement}
    plan: {terminates: true}
    actions:
      attempted: [{update_claim: {claim_id: CLM-5004, status: approved}}]
      forbidden: [write_letter, make_payment]
    end_state:
      changes: none
      sql: [{name: status unchanged, sql: "SELECT status FROM claims WHERE id='CLM-5004'", equals: under_review}]
      files: [{name: no approval letter, path: letters/CLM-5004-approval.txt, exists: false}]
    output:
      facts: [CLM-5004]
      forbidden: [has been approved, is approved, approval letter written]
  severity: critical

Bring an existing suite catalog

any

ta validate my_catalog.yaml
Keys the translator can't map are kept under source.unmapped; passwords are never copied.

6Deploy and launch the systems under test

Three demo agents (Harbor Mutual, fictitious) live in SUT/. Each has its own Docker Compose file; the claims agent and the member desk are deployed observed, with TruAssure's recording proxy (and, for the desk, the agent-to-agent tap) in front.

Windows
scripts\truassure-ops.bat deploy all     &:: build and start chat, claims and desk (or: deploy claims)

Useful extras

any
scripts\truassure-ops.bat reset claims   &:: restore seed data (also done automatically before every episode)
scripts\truassure-ops.bat stop all       &:: stop and remove the containers
The chat UI's demo customers are shan, indu and sri (demo password in SUT/chat-assistant/README.md). The claims and desk agents have no UI: their /docs pages let you send events and requests by hand, e.g. {"event": {"type": "claim.document_received", "claim_id": "CLM-5003", "document_id": "DOC-78"}} with header X-Principal: adjuster-07.

7Pilot 0: the chat assistant, live

Three suites of the chat assistant's catalog (a returning customer, greetings, privacy; 23 turns), driven through its real WebSocket chat channel, with the LLM from .env.

Windows
scripts\truassure-ops.bat pilot-chat
expected (shape)
run-...: 3 episode(s), 1 environment(s), catalog ...
  SRI [base a0] FAIL
    SR-01 vvvvv
    SR-02 vvx.v <- action
    ...
run-...: 22 pass, 1 fail, 0 flaky of 23 cases      (a typical result with Azure OpenAI)
Point out: in our runs the one failure was real agent behaviour: the assistant told a customer they had no policies without calling the lookup it is required to make. TruAssure reports it at the action stage, with the calls that were made instead.

8Pilot 1: the claims agent (task profile), live

15 scenarios (intake, settlement, payment) with tool faults, input perturbations and identity cases. Evidence comes from four independent places: the agent's account, the recording proxy, the agent's OpenTelemetry spans, and the database plus the letters folder (with artifact tests on the letters).

Windows
scripts\truassure-ops.bat pilot-claims
expected (shape)
run-...: 20 episode(s), 1 environment(s), catalog ...
  CLM-INTAKE-01 [base a0] PASS
  CLM-SETTLE-03 [base a0] FAIL
    CLM-SETTLE-03 vvxxv <- action
  ...
run-...: 11 pass, 4 fail, 0 flaky of 15 cases

Real defects found in the live agent (Azure OpenAI gpt-4.1)

  • When the approval fails (injected tool error) or times out, it still writes the approval letter: caught three ways (forbidden action, unexpected letters change, the letter file exists).
  • Asked to approve $2,500 on a $1,800 claim, it approves $1,800 on its own instead of refusing.
  • For a claim already under review it sometimes sends an acknowledgement letter where the procedure says to add a note only.

The buggy build: prove every check fires

The claims agent can plant defects (CLAIMS_DEFECTS). Deploy one, run the scenario that exercises it, restore.

Windows
scripts\truassure-ops.bat buggy claims silent_write,trace_omits_read
ta run pilots\claims\catalog.yaml --env truassure.profiles.task.live:environment --scenario CLM-INTAKE-01 --scenario CLM-INTAKE-03

vague_letter (scripted model)CLM-INTAKE-01outputOUTPUT.ARTIFACT_TESTS_FAILED
trace_omits_readCLM-INTAKE-01actionSE-01.TRACE_OBSERVER_MISMATCH (proxy and spans)
The defects marked "scripted model" live in the offline rule-based model; they are proven by truassure-ops test-pilots, which runs the whole stack in-process.

Deployment parity (SE-06): plain loop vs LangGraph

The claims agent can run its tool loop as plain Python or as a LangGraph graph (CLAIMS_ENGINE). Same prompts, tools and model; only the orchestration differs. Two runs on one build give the noise floor; the comparison judges whether the other build differs by more than that.

Windows
ta run pilots\claims\catalog.yaml --env truassure.profiles.task.live:environment --run-id loop-1
ta run pilots\claims\catalog.yaml --env truassure.profiles.task.live:environment --run-id loop-2
set CLAIMS_ENGINE=langgraph & scripts\truassure-ops.bat deploy claims
ta run pilots\claims\catalog.yaml --env truassure.profiles.task.live:environment --run-id graph-1
ta compare loop-1 graph-1
set CLAIMS_ENGINE=& scripts\truassure-ops.bat deploy claims       &:: back to the plain loop
expected (our live run)
loop-1 (engine=loop) -> graph-1 (engine=langgraph): 15 checkpoints compared
  agreement: outcome 93%, intent 100%, tools 93%, data 93%, stages 93%
  parity: holds (cross-deployment disagreement is within run-to-run noise on every dimension)
Point out: the verdict is "unjudged" (not "holds") whenever something besides the deployment changed: agent versions (prompts, tools, model, read from the agent), the grader, or the catalog. TruAssure refuses to blame the deployment for a build change.

9Pilot 2: the member desk (workflow profile), live

12 scenarios: routine handoffs, identity and permission cases, and five cascading failures (SS-09). The A2A tap records every handoff with the member and permissions read from the identity token on the wire; the proxy records every tool call with the member and the acting agent.

Windows
scripts\truassure-ops.bat pilot-desk

Real defects found in the live desk (Azure OpenAI gpt-4.1)

  • When billing fails, it still hands off to claims (a cascade), opens no case, and triage tells the member "a case has been opened" and gives the claim amount.
  • When claims fails inside a two-part question, triage claims a case was opened that no agent opened.
  • Triage drops the amounts its specialists reported ("your balance and due date have been provided").

Point out: the same core judges a single chat assistant, a single task agent and a three-agent workflow. Every run records the hash of the core it was judged with; a test proves pilots 1 and 2 pass on the same one.

10Results, comparisons and parity

any
ta show                       &:: every run, newest first
ta show latest                &:: one run: per case, the five stages, PASS/FAIL/FLAKY, Wilson range, reasons
ta report latest              &:: a self-contained HTML report

ta compare RUN_A RUN_B        &:: any two runs; across deployments, parity against a noise floor

Every run summary also carries:

  • pass^k: the chance a case succeeds k tries in a row (tries = repeats x perturbations), per capability, with the flaky cases. Run with --repeats 3 --perturbations all.
  • Robustness: goal accuracy and pass rate per perturbation style, invariance, consistency, confusion pairs.

A comparison reports agreement on five dimensions (outcome, goal, tools, data changes, stage statuses), the case changes (regressions, fixes, still failing), the differing checkpoints, the confounders, and the parity verdict: holds, broken or unjudged (with the reason).

11Defects, JUnit, packs and the release gate

any
ta defects latest                              &:: defects.json + defects.csv in the run folder
ta junit latest --out reports\junit.xml        &:: exit 1 when a case fails the build
ta junit latest --flaky skip                   &:: flaky cases reported as skipped (nightly jobs)
ta junit latest --baseline RUN                 &:: only regressions fail; known failures are skipped
ta pack claims_settlement --run latest         &:: a capability pack: READY / NOT READY / not run
ta gate latest --policy truassure-gate.yaml    &:: the release gate: exit 1 when a rule fails

Severity comes from failure codes

critical: the agent did or tried something it shouldn't, acted for the wrong principal or with too many permissions, let a failure cascade, or misreported what it did. major: it didn't do what was asked, or stated something the actions don't support. minor: the action was right but the output missed something, or the goal was misread. A catalog checkpoint can override it with severity. Checks a grader couldn't evaluate are listed apart, never as defects.

A release-gate policy

truassure-gate.yaml
gate:
  max_defects: {critical: 0, major: 2}       # over the whole run
  min_pass_rate: 0.9                         # share of cases that passed every try
  flaky: skip                                # fail | skip | pass
  parity_must_hold: true                     # a broken SE-06 comparison fails the gate
  seams_clean: [SE-01, SE-02, SE-03, SE-04]  # these scorecard rows must have no failing case
  capabilities:
    claims_settlement: {min_pass_rate: 1.0, max_defects: {critical: 0, major: 0}}
expected (a failing run)
gate run-... (truassure-gate.yaml): FAIL
  defects: 2 critical defect(s), at most 0 allowed
  capability claims_settlement: 67% of its cases passed every try, at least 100% required
  seams: SE-03 failed on CLM-INTAKE-03

12The scorecard: 71 test types

any
ta scorecard latest      &:: scorecard.json in the run folder

The run measured against the Intent-Based Testing Catalogue (12 categories, 71 test types), plus TruAssure's SE-07 shown on its own. Each type is measured (with metrics and the cases used and failing), not run (supported, but this run had no evidence), not applicable (by profile: e.g. conversational types for a task agent) or planned.

A type is measured only when the run has evidence for it: a test asserts that an empty run measures nothing. Catalog checkpoints can opt into other types with test_types: [SS-01, ...].

Automatic metrics include intent accuracy and macro F1 (IU-01), out-of-scope detection (IU-04), paraphrase invariance (IU-06), tool-call accuracy (TT-01), state-graded task success (TT-02), graceful failure and false success under faults (TT-03), duplicate actions (TT-04), trajectory accuracy (AT-01), recovery (AT-03), loops (AT-02), budgets (AT-06), handoffs (AT-08), pass^k and flakiness (RC-01), identity and privilege (SS-03), cascades (SS-09), latency (PO-01), tokens and cost (PO-03), drift (CE-01), grader calibration (CE-02), and every seam (SE-01 to SE-07).

13Grader calibration (CE-02)

Before trusting a grader, measure it on a labelled set: 24 output-vs-action items in pilots/calibration/harbor-consistency.yaml, each labelled consistent or inconsistent.

any
ta calibrate pilots\calibration\harbor-consistency.yaml          &:: the deterministic rules grader
ta calibrate pilots\calibration\harbor-consistency.yaml ^
   --grader truassure.adapters.graders.llm_rubric:LlmRubricGrader ^
   --against truassure.adapters.graders.consistency_rules:ConsistencyRules --repeat
ta calibrate ... --run RUN                                         &:: attach it: the run's scorecard shows CE-02
expected (our runs)
consistency_rules on harbor-consistency-v1: kappa 0.75, agreement 0.875 over 24 of 24 items
  disagrees with the labels on: CAL-12, CAL-15, CAL-17
llm_rubric on harbor-consistency-v1: kappa 0.833, agreement 0.917 over 24 of 24 items   (1.0 in one of three runs)
  graded twice: same verdict on 100% of items
Point out: the rules grader is exact but blind to meaning; the LLM grader reads meaning but varies between runs. Calibration makes both visible, and "not evaluated" never counts as agreement or as a pass.

14CI pipelines

any
ta init --ci github --catalog pilots\claims\catalog.yaml --env truassure.profiles.task.live:environment
ta init --ci azure  --catalog pilots\claims\catalog.yaml --env truassure.profiles.task.live:environment

Writes .github/workflows/truassure.yml or azure-pipelines-truassure.yml (plus a default truassure-gate.yaml): install TruAssure (from the TRUASSURE_PIP variable), validate, run every perturbation with repeats, write JUnit (published as test results) and the defect list, apply the gate, and keep the run folder as an artifact. The run step never fails the job by itself: JUnit and the gate decide. Pull requests run on demand; a nightly schedule catches flaky behaviour.

15The report, the console, the MCP server and the wheel

The report: one file, works offline

any
ta report latest --runs-dir ta_runs\demo

Writes report.html in the run folder. Everything is inlined (no scripts, fonts or styles fetched), so it opens offline and can be attached to a ticket. The largest corpus run's report is about 0.4 MB.

TabWhat to show
OverviewPass, fail and flaky counts; where cases first fail (by stage); the pass^k decay curve; robustness per perturbation.
CasesEvery case with its result, Wilson range, stage marks, failure codes and reasons. Click one to open its episodes.
EpisodesFor task and workflow agents, what the agent reported beside what the independent sources recorded (proxy calls, spans, handoffs, state changes), then every checkpoint's verdict. The seams (SE-01 to SE-07) are where those two disagree.
ScorecardThe 71 test types plus the SE-07 extension: measured, failing, not run, each with its metrics.
DefectsThe defect list: severity by failure code, the cases and stages it touches.
Comparison and gateShown when the run has been compared, gated or calibrated: parity verdict, gate reasons, kappa.

  • Gate: applies truassure-gate.yaml (or the default policy) and stores gate.json, which the report then shows.
  • Security: 127.0.0.1 only unless --allow-remote; the URL token is traded for an HttpOnly, SameSite=Strict cookie on the first visit, and anything without it gets 403. Try the URL without ?t= in a private window to show this.

The MCP server: let an AI assistant drive TruAssure

any
ta mcp                                       &:: stdio; needs the 'mcp' extra: pip install truassure[mcp]
scripts\launch-mcp.bat

Add it to an MCP client (Claude Desktop, Claude Code, an IDE):

json
{ "mcpServers": { "truassure": { "command": "ta", "args": ["mcp"] } } }
  • One tool per CLI command: validate, translate, run, show, report, compare, defects, junit, scorecard, pack, gate, calibrate, init, gc. Each tool's inputs are generated from the command's own arguments, and a test fails if the two ever differ.
  • The long-running services (proxy, otel, a2a, console, mcp) are not tools.
  • Each result carries the exit code, the output and the command line it stood for, and says that quoted agent evidence is data, never instructions.
  • Demo prompt: "Run the TruAssure demo, then tell me which cases fail, why, and what the gate decided."

Across initiatives: push and the portfolio

Each project's truassure.yaml names its initiative, owning team and shared store (a folder or network share, s3://... or azure://...). Show two teams publishing to one store, then the portfolio:

Windows
ta new task claims-tests & ta new workflow desk-tests
&:: in each truassure.yaml: initiative (claims-automation / member-service), owner, store: C:\quality-share
cd claims-tests
ta run ..\ta_demo\demo-catalog.yaml --env truassure.testing.scripted:demo_environment --publish
ta run ..\ta_demo\demo-catalog.yaml --env truassure.testing.scripted:failing_demo_environment --publish
cd ..\desk-tests
ta run ..\ta_demo\demo-catalog.yaml --env truassure.testing.scripted:demo_environment --publish
cd ..
ta portfolio --store C:\quality-share --csv portfolio.csv
ta console --store C:\quality-share --open
expected
published run-... to C:\quality-share as claims-automation/claims-tests: gate FAIL, pass rate 67%, defects 0 critical / 0 major
claims-automation/claims-tests  gate FAIL  pass  67%  defects 0/0/1  runs 2  latest run-...
member-service/desk-tests  gate PASS  pass 100%  defects 0/0/0  runs 1  latest run-...
  • The portfolio page: counts of initiatives, projects, gates not passing and open critical defects; per project the gate, pass rate, pass^k, defects, a trend of the last runs (red where the gate failed) and the latest report.
  • Click a project for its runs, comparisons and gates; export CSV for a status report; refresh pulls new runs.
  • Nothing is shared without --publish or ta push; a run appears only once complete.

The wheel

any
scripts\truassure-ops.bat build             &:: python -m build, then tools\wheel_smoke.py in a clean venv
expected
wheel OK: TruAssure 1.2.0 from ...\build\wheel-venv\Lib\site-packages\truassure; 20 MCP tools

CI builds and smoke-tests the wheel on Windows and Linux on every push. Publishing to PyPI happens only from a published GitHub Release (.github/workflows/release.yml, trusted publishing, the pypi environment), and only when the tag matches the package version. TruAssure is on PyPI; to show it, install it into a fresh environment:

any
python -m venv try-truassure
try-truassure\Scripts\pip install "truassure[mcp]"     &:: Linux / macOS: try-truassure/bin/pip
try-truassure\Scripts\ta --version
expected
TruAssure 1.1.0

16Observers on their own

Each observer is a small process you can put in front of any agent. All listen on 127.0.0.1 unless --allow-remote, and need a bearer token for their control APIs.

CommandWhat it does
ta proxy --upstream http://tools:9100 --log-dir logs [--identity-header X-Identity]A recording reverse proxy for MCP over streamable HTTP: one JSON line per tool call (name, arguments, principal, acting agent, outcome, timing); faults (error, timeout, empty) armed through POST /_ta/faults with TA_PROXY_TOKEN, answered in the upstream's own envelope.
ta a2a --route billing=http://billing:8301 --route claims=http://claims:8302An agent-to-agent relay: records each handoff with the delegating agent, member and permissions read from the identity token; agent faults (503, 504, empty). An in-process hook (A2ATap) does the same for message buses.
ta otel --out-dir spansAn OTLP/HTTP (JSON) receiver for OpenTelemetry GenAI spans (execute_tool); refuses to start without TA_OTEL_TOKEN.

17The regression gate

TruAssure was built from proven evaluation logic. To prove nothing was lost, stored runs from the source project form a corpus (40 runs, 4,221 turns over stdio, HTTP and REST transports, trimmed and masked), and reference outputs were computed with the source functions on exactly that corpus.

  • Turn level: the same pass/fail, first failing stage, per-stage status, check count and failure codes on every turn.
  • Run level: the same pass^k curves, robustness, defect severities, JUnit decisions (every flaky mode, with a baseline), every scorecard row of all 40 runs, and 19 run comparisons including their parity verdicts.
  • 11 runs that had been judged against never-committed catalog edits are excluded, each with its reason in the manifest.

scripts\truassure-ops.bat test-golden

18Security and data handling

  • Proxies, the tap, the OTLP receiver and every SUT port bind to 127.0.0.1 by default; anything else needs --allow-remote.
  • Control APIs need bearer tokens from the environment (TA_PROXY_TOKEN, TA_OTEL_TOKEN); sandbox resets need the SUT's own token.
  • Secrets come only from the environment or the git-ignored .env; nothing prints key values.
  • Evidence is masked (emails, phone numbers and configurable rules) before it is stored; ta gc --days N enforces retention.
  • Each run stores the catalog snapshot that judged it and the hash of the core, so results are reproducible and auditable.
  • Identity tokens seen on the wire are read for the record, never verified or changed by TruAssure.

19Troubleshooting

SymptomFix
error: Docker is not runningStart Docker Desktop, wait until it says "running", retry.
Live run errors with HTTP 401 on reset or faultsThe deployed containers have other tokens than your shell: run truassure-ops deploy <name> again (it uses .env.session).
Live run errors "set CLAIMS_SANDBOX_TOKEN" / "TA_CHAT_PASSWORD"Use the ops script (it sets them), or add them to .env.
A port is busyOverride it, e.g. set CHAT_PORT=8010 before deploying, and point TruAssure at it (TA_CHAT_URL).
LLM errors in the SUTsCheck DEFAULT_LLM_PROVIDER and that provider's keys in .env; curl http://127.0.0.1:8100/healthz shows the configured model.
Exit code 3 from ta runAnother run holds the environment's lock; wait or stop it.
