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
Section 2 (setup, once), then section 4: one command runs the whole offline tour. No Docker and no LLM key needed.
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
| What | Why | Check |
|---|---|---|
| Python 3.11 or 3.12 | TruAssure and the SUT test environments | py -3.12 --version / python3 --version |
| Docker Desktop (running) | The three systems under test, the recording proxy and the A2A tap | docker info |
An LLM key in the root .env | The SUTs' model (live runs) and the LLM grader | DEFAULT_LLM_PROVIDER=AZURE plus AZURE_*, or any provider in .env.example |
| Git, curl | Cloning; health checks in the scripts | git --version, curl --version |
.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.

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).
Five stages, in order
| Stage | Question | Typical evidence |
|---|---|---|
| goal | Did it understand the request (intent, route)? | The agent's decision in its trace |
| plan | Was the way it worked acceptable (approvals, loops, budgets, handoffs, containment)? | Trace, approvals, handoffs |
| action | Did it call the right tools with the right arguments, for the right principal? | Trace vs proxy, spans and tap |
| end_state | Is the system of record in the expected state? | Database and file diffs, SQL and file checks |
| output | Is 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
Three profiles
One checkpoint per user turn (chat assistants). Perturbations are rephrasings.
One event or task, judged once at the end (back-office agents). Perturbations change input fields or add noise (duplicate events).
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.

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):
- 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: criticalWhat a catalog can say
| Block | Keys |
|---|---|
| Input | prompt (chat), event or task, attachments, perturbations (rephrasings, field overrides, noise: duplicate_event) |
| Faults | action, mode (error, timeout, empty), times, delay_s, message |
| goal / plan | intents, route; max_calls, max_steps, max_loops, terminates, handoffs (+ max_permissions, principal_preserved), handoffs_ordered, contain_failures |
| actions | required, attempted, preferred, forbidden, must_not_succeed, allowed, no_writes |
| end_state | changes (none, scopes, or per adapter), sql, files, git, saas |
| output | facts (with "a or b" alternatives), forbidden, rubric, artifact (path, content checks, a test) |
| Governance | severity, test_types (catalogue ids), capabilities, budgets |

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.

- 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.

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.

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.
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").

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).

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

max_defects: {critical: 0, major: 2} # over the whole run

12The scorecard: 71 test types
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.
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.
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

14CI pipelines
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
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.
| Tab | What to show |
|---|---|
| Overview | Pass, fail and flaky counts; where cases first fail (by stage); the pass^k decay curve; robustness per perturbation. |
| Cases | Every case with its result, Wilson range, stage marks, failure codes and reasons. Click one to open its episodes. |
| Episodes | For 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. |
| Scorecard | The 71 test types plus the SE-07 extension: measured, failing, not run, each with its metrics. |
| Defects | The defect list: severity by failure code, the cases and stages it touches. |
| Comparison and gate | Shown when the run has been compared, gated or calibrated: parity verdict, gate reasons, kappa. |
Deep links: report.html#tab=episodes&case=DM-01 opens one case's episodes.
The console: browse every run
scripts\launch-demo.bat &:: offline demo, then the console over its runs scripts\launch-console.bat ta_runs\demo &:: or: scripts\truassure-ops.bat console ta_runs\demo ta console --runs-dir ta_runs\demo --open
TruAssure console: http://127.0.0.1:8765/?t=<random token> (the token in the URL is your key; Ctrl+C stops the console)
- The run list shows each run's result, with links to its report, defect CSV, scorecard and gate.
- Compare: pick two runs. Same deployment: agreement, regressions and fixes. Across deployments: the parity verdict too.
- Gate: applies
truassure-gate.yaml(or the default policy) and storesgate.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
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):
{ "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 e2e demo catalog with the scripted demo environment, then tell me which cases fail and apply the gate."
The wheel
scripts\truassure-ops.bat build &:: python -m build, then tools\wheel_smoke.py in a clean venv
wheel OK: TruAssure 1.0.0 from ...\build\wheel-venv\Lib\site-packages\truassure; 14 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).
Nothing has been published.
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.
| Command | What 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:8302 | An 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 spans | An 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 Nenforces 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
| Symptom | Fix |
|---|---|
error: Docker is not running | Start Docker Desktop, wait until it says "running", retry. |
| Live run errors with HTTP 401 on reset or faults | The 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 busy | Override it, e.g. set CHAT_PORT=8010 before deploying, and point TruAssure at it (TA_CHAT_URL). |
| LLM errors in the SUTs | Check 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 run | Another run holds the environment's lock; wait or stop it. |
| Accented or symbol characters garbled in a Windows console | Output is ASCII-safe; set PYTHONIOENCODING=utf-8 for full fidelity. |

BThe ta command
| Command | Purpose |
|---|---|
validate, translate | Check catalogs; convert a suite catalog |
run CATALOG --env module:factory | Options: --perturbations all|0,1,2, --repeats N, --parallel N, --scenario ID, --run-id, --step-timeout, --mask LABEL=REGEX, --runs-dir. Exit 0 all pass, 1 any fail/flaky, 2 bad input, 3 locked. |
show, report, gc | List and inspect runs; HTML report; retention |
compare, defects, junit, scorecard, pack, gate, calibrate, init | Run-level analysis and governance (sections 10 to 14) |

Ready-made environments for --env: truassure.testing.scripted:demo_environment (offline),
truassure.profiles.conversational.live:environment (chat), truassure.profiles.task.live:environment
(claims), truassure.profiles.workflow.live:environment (desk). Your own agent needs a factory function
returning an Environment (driver, observers, state adapters, graders).
