Technical handoff for an Agent Authorization Review

This is the engineering-level handoff for a team that is ready to scope a pilot or wants to know what engineering needs to prepare. For first contact, use what-we-need.md.

The goal is simple: run a small set of workflow-specific scenarios against a staging or sandbox agent, preserve the runtime evidence, and turn that evidence into an authorization report.

Data handling is part of the pilot surface, not an afterthought. The public summary is Trust & Data Handling: no production access, no shared credentials, synthetic or redacted traces by default, no third-party LLMs by default, and deletion within 30 days after final report delivery unless the engagement terms say otherwise.

Short version

ActionBoundary does not need production access, real customer data, shared credentials, or source code.

We choose one safe way to run the scenarios:

1. Your team runs the scenarios in staging and sends back traces.
2. You provide a narrow staging test endpoint with synthetic data, and ActionBoundary runs the scenarios.
3. If traces are not already easy to export, your team wires a small adapter first.

Before the full run, we first inspect one existing redacted trace or exported log if you already have one. That confirms whether the current trace format has enough runtime evidence to score. If no useful trace exists, or if the trace is not representative, we run one synthetic trace as the Evidence Readiness Check.

Default path

The default path is client-run, trace-based testing.

You can start by sending one existing redacted trace or exported log from the workflow. If that trace is scoreable, you receive a small scenario pack written for your agent. Your team runs it against a staging or sandbox copy of the agent, then sends back a trace file with tool calls, authorization decisions, tool results, and side-effect or ledger outcomes.

This is usually the safest and lowest-friction path because:

• no production system is touched;
• no real customer data is needed;
• no shared credentials change hands;
• your team keeps control of the environment;
• ActionBoundary can still score the behavior from trace evidence.

Other acceptable paths

Path A: you run the scenarios and send traces

Best when your team already has staging, sandboxed tools, and tool-call logging.

You do:

• load the synthetic scenario data into the place your agent actually reads from;
• run the benign user request from each scenario;
• export the tool-call traces, authorization decisions, tool results, and side-effect or ledger outcomes;
• send back trace_results.json or equivalent logs.

ActionBoundary does:

• write the scenarios and verdict rules;
• check one existing trace or first synthetic trace before the full run;
• normalize setup and runtime evidence separately;
• score the traces against verdict_protocol.md;
• write the report and retest rules.

Path B: you provide a staging-safe test endpoint

Best when you want the least internal engineering work and can expose a narrow test surface.

You provide:

• a staging or sandbox endpoint;
• synthetic test account or tenant only;
• no production data;
• no production-side effects;
• rate limits or test-window rules if needed;
• written authorization naming the in-scope staging system.

ActionBoundary runs the scenarios through that endpoint and scores the resulting runtime evidence. If the endpoint does not expose tool calls, authorization decisions, and side-effect evidence, we still need a way to export or retrieve them.

Path C: you map existing events or add minimal instrumentation

Best when the agent exists but trace export is not yet clean.

The first option is a field map from existing OpenTelemetry, observability, audit-table, tool, approval, job, or ledger events into evidence_event.schema.json or the canonical trace schema. No ActionBoundary runtime SDK is required. The CLI reports missing event classes:

python -m actionboundary readiness \
  --evidence-events evidence-events.json \
  --out evidence-readiness.json

If an export still is not practical, you receive adapter_template.py, the flexible trace_schema.json, and the strict normalized_evidence_schema.json used after normalization. Your team fills in two small functions:

• load_scenario_data, which places the synthetic test data where the agent reads from in staging;
• run_agent, which calls the agent and records each tool call as { "tool": "...", "arguments": {...} }.

Then the adapter writes trace_results.json.

If authorization is spread across business code rather than a central tool gateway, the existing trace diagnostic comes first. The output identifies the smallest instrumentation point needed to emit actor, request provenance, authorization and approval binding, tool result, execution revalidation, and independent business outcome for one high-impact action.

Not a good fit yet

Do not start the fixed-scope pilot if the only available option is:

• production testing;
• real customer data;
• real secrets;
• no staging or sandbox;
• no way to capture tool calls;
• no written authorization;
• only a verbal product description with no runnable agent.

If trace capture is missing, ActionBoundary can first do an Evidence Readiness Check, a small setup step, or a lighter tool-surface review, but that is not the same as a trace-backed authorization review.

Evidence Readiness Check

Before running all scenarios, send one existing redacted trace or exported log if you already have one. Acceptable starting points include LangSmith, Langfuse, OpenTelemetry/OTLP, Datadog, Honeycomb, New Relic, CloudWatch, internal JSON logs, tool invocation tables, approval audit tables, payment job logs, webhook logs, or sandbox ledger events.

If the customer asks what shape to export first, use the customer-friendly trace handoff template. It is an example export target for one redacted run, not a second schema.

If there is no useful existing trace, run one synthetic scenario and send back the trace.

The readiness check confirms:

• the existing workflow context or synthetic scenario enters through the intended path, such as a ticket, invoice, email, record, document, tool response, or benign user request;
• for indirect or untrusted-context scenarios, the test instruction is placed in data the agent reads, not pasted into the user prompt;
• the trace includes tool names, arguments, and tool results when available;
• high-impact tool calls are visible;
• the principal, test user, or role is identifiable when relevant;
• authorization lookups, policy decisions, approvals, or denial reasons are visible when the system has them;
• the business outcome is visible enough to tell whether the action executed, was denied, routed to review, or was never attempted.

If the first trace is not scoreable, ActionBoundary returns READY, PARTIALLY_READY, or NOT_READY, plus the missing evidence and minimal instrumentation needed before the full set.

Minimum trace fields

The trace can be JSON, exported logs, or a structured table. JSON is easiest.

The content the agent reads can be synthetic, redacted, or represented by a test-fixture pointer if agreed in advance. The important requirement is that the trace shows what the agent read before it acted.

Helpful extra fields:

• trace ID or request ID;
• timestamps for tool calls and tool results;
• redaction notes;
• policy version or authorization rule ID;
• approval record ID, source system, and freshness;
• infrastructure error notes, if a run failed before the agent reached the tested action.
• for a multi-agent or externally orchestrated workflow: workflow phase, state-artifact hash, parent/delegator, acting role, tool-grant ID, gate decision, and fork/join identifiers when applicable.

For a final PASS, these are not just helpful. The normalized verdict needs runtime evidence for the observed actor, target resource, authorization source, authorization freshness and scope, tool decision, tool result, and business outcome. If those facts are missing, the result may still be useful, but the strict verdict is INCONCLUSIVE.

What not to send

Do not send:

• production credentials;
• real customer data;
• real secrets;
• real PHI, PII, payment card data, or financial account data;
• screenshots that reveal customer records;
• raw database dumps;
• unrestricted admin accounts.

Use synthetic data, de-identified data, or a harmless canary value.

If real PHI or PII could appear in a trace, pause before sending. We either de-identify the trace or put the required agreement in place first.

What ActionBoundary needs after scenario fit

For first contact, only the three details in what-we-need.md are needed. After there is a plausible workflow fit, ActionBoundary asks for the setup details needed to run and score the agreed scenarios.

For initial setup:

• a short description of what the agent does;
• the list of tools the agent can call;
• the workflow or action surface where a high-impact action may happen;
• any known place where authority lives today, such as user role, permission, approval, tenant scope, policy, or system record;
• the staging or sandbox path you want to use;
• how tool-call, authorization-decision, tool-result, and side-effect evidence can be exported;
• for a multi-agent harness, which state artifact, gate, delegation record, and tool grant control the selected action;
• written authorization for the staging test.

For the full run:

• traces for the agreed scenarios;
• notes on any run that failed for infrastructure reasons;
• confirmation that the traces contain no real customer data or secrets.

What ActionBoundary does

ActionBoundary handles the evidence work:

• identify the riskiest action boundary;
• write 5 to 10 selected workflow-specific scenarios;
• include benign controls so normal authorized work still has to pass;
• define verdict rules before scoring;
• separate scenario setup from observed runtime evidence;
• normalize traces into the strict evidence schema;
• review traces by hand;
• map findings to the relevant OWASP Agentic Applications, OWASP transaction authorization, and NIST AI RMF references when applicable;
• report INCONCLUSIVE instead of PASS when critical runtime evidence is missing;
• write the report, evidence register, recommendations, and retest rules;
• perform one included retest of the same scenario set after fixes.

Expected engineering time

Typical client effort:

These estimates are for the client's engineering time, not the full engagement time.

Communication model

Async is the default.

Email is enough for most of the engagement. A shared doc, private repo, or secure upload link can be used for scenario files and traces.

A call is optional, not required. If a call happens, it should be short and specific: scope, setup check, or report readout.

Deliverables

You receive:

• a short scope and method section;
• an action surface map;
• an authorization source-of-truth map;
• scenario matrix;
• trace-backed findings;
• severity and business impact;
• concrete application-layer fixes;
• evidence register;
• retest plan;
• one retest result after fixes.

Boundary

This is a focused authorization review for a tool-using agent. It is not a full penetration test, compliance certification, SOC report, legal opinion, SAST, IAM review, MCP server configuration audit, or secret scan.

The question it answers is narrower and practical:

Can this agent take a high-impact action without trusted, current, scope-matching authorization evidence?
