feat: implement AI support agent (005) — diagnosis, tools, runbooks, verification
Real Anthropic Claude integration per explicit product decision: a ticket's AI session diagnoses the problem via a structured-output call, applies a DB-configurable confidence-band policy (FR-005), and on "proceed" reasons and acts through a small permission/risk-gated tool system (FR-011/FR-012), optionally walking a matching runbook step by step with the application — never the model — owning the step index (FR-015/FR-016). Resolution requires real tool evidence, never customer claims alone (FR-018) — verifyProductResolution is a documented fail-closed placeholder mirroring the existing malware-scanner precedent, since no real per-product operational signal exists yet. AISupportSession.status mirrors onto Ticket.status through 003-ticketing's existing AI_ANALYZING/AI_TROUBLESHOOTING/AI_VERIFYING/AI_RESOLVED/ HUMAN_ESCALATION state machine, discovered during planning to have been built anticipating this exact feature. Two circular module dependencies (escalation<->sessions, tools<->sessions) were designed around rather than found as bugs: escalation is a pure summary formatter with no state dependencies of its own, and tools stays a clean leaf module with zero dependency on ai-support/sessions. Ticket creation enqueues the first diagnosis turn via the existing queue infrastructure (off the hot path of the inbound SaaS integration endpoint); a human actor changing ticket status ends the AI session via the event-bus scaffold that existed in this codebase but had never been wired to anything. A real Prisma limitation was found and fixed before it reached tests: compound-unique upsert rejects null for a nullable key column, so AIConfidencePolicy uses find-then-update/create instead, same fix class 004 already used for the same underlying limitation. Adds 9 unit tests (confidence-band, tool-policy-gate, runbook-step- advance) and 6 integration test files, including the two constitution- required standing E2E scenarios. AI-independent tests were run against real Postgres/Redis/MinIO (88 passed, 0 failed across the full suite, including every pre-existing 002/003/004 test). The AI-dependent tests compile and skip cleanly via describe.skipIf but were not run against a live model — no ANTHROPIC_API_KEY was available in this session; a real key must be supplied before this feature can actually run.

# AI Support
|
||||
A ticket's AI session diagnoses the problem via a real Anthropic Claude call, applies a
|
||||
configurable confidence-band policy, and — on "proceed" — reasons and acts through a small,
|
||||
permission/risk-gated tool system, optionally walking a matching runbook step by step. See
|
||||
`specs/005-ai-support/contracts/ai-support-contract.md` for the full route list and
|
||||
`specs/005-ai-support/quickstart.md` for runnable scenarios.
|
||||
|
||||
- **Requires a real `ANTHROPIC_API_KEY`** (per explicit product decision — not a mock or
|
||||
pluggable-interface phase). The app boots and every non-AI test still passes without one; an AI
|
||||
session simply fails closed (escalates) if a reasoning call is attempted with none configured.
|
||||
`AI_SUPPORT_MODEL`/`AI_SUPPORT_EFFORT` and the system-wide confidence-threshold/question-budget
|
||||
defaults are all environment-configurable, never hardcoded (doc 11 §B2).
|
||||
- **Session lifecycle**: a session starts automatically (queued, off the hot path of
|
||||
`POST /v1/support/requests`) when a ticket is created, and its status mirrors onto
|
||||
`Ticket.status` through 003-ticketing's *existing* state machine (`AI_ANALYZING` →
|
||||
`AI_TROUBLESHOOTING` → `AI_VERIFYING` → `AI_RESOLVED`, or `HUMAN_ESCALATION` from any point) —
|
||||
see `specs/005-ai-support/research.md` "AISupportSession.status drives Ticket.status". A
|
||||
customer reply is `POST /tickets/:ticketId/ai-session/messages`; the current session (with its
|
||||
diagnosis and conversation) is `GET /tickets/:ticketId/ai-session`.
|
||||
- **Confidence policy**: `PUT/GET /admin/products/:externalProductId/ai-policy` sets
|
||||
per-product (optionally per-category) `highThreshold`/`lowThreshold`/`maxClarifyingQuestions`,
|
||||
falling back to env-configured system defaults when nothing is configured — applies to the
|
||||
very next diagnosis, no deploy required.
|
||||
- **Tool system**: every tool call the AI proposes is evaluated by a deterministic policy gate
|
||||
(`src/modules/ai-support/tools/service/policy-gate.ts`) before anything executes — the gate
|
||||
never reads the AI's own proposal/justification text, only the tool's declared risk level and
|
||||
product scope. Low-risk tools (`getTicketSnapshot`, `searchProductKnowledge`,
|
||||
`verifyProductResolution`, `escalateToHuman`) auto-execute; `overrideTicketPriority` is
|
||||
high-risk and **always** stays `pending_approval` — there's no human-approval UI yet (Phase 10),
|
||||
so it never actually runs, by design, not by oversight. Every proposal, decision, and result is
|
||||
recorded and auditable via `GET /tickets/:ticketId/ai-session/actions`.
|
||||
- **`verifyProductResolution` is a documented, fail-closed placeholder** (same pattern as
|
||||
`ticketing/attachments`'s malware scanner) — it always returns `confirmed: false`, since there's
|
||||
no real per-product operational signal to check yet (doc 11 §A2). A ticket is only ever marked
|
||||
`AI_RESOLVED` on a passing result from this tool, never from what the customer says alone — so
|
||||
in practice, genuinely automatic AI resolution won't happen until a real verification signal
|
||||
replaces this placeholder.
|
||||
- **Runbook engine**: when a diagnosis's `problemType` matches a runbook's `key` for the
|
||||
product (004-product-knowledge), the application — never the model — tracks which step is
|
||||
current (`currentStepIndex`) and advances it by exactly one at a time; exhausting every step
|
||||
without resolving escalates with the full attempted sequence attached.
|
||||
- Semantic/vector retrieval, product-signal webhook verification, model routing/fallback, cost
|
||||
dashboards, and localization are intentionally out of scope here — see
|
||||
`specs/005-ai-support/spec.md` Assumptions.

|

## Implementation notes (added during /speckit-implement)
|
||||
|
||||
- **Two circular module dependencies were designed around during implementation, not discovered
|
||||
as bugs after the fact**: (1) `escalation` initially needed `sessions`' repositories to end a
|
||||
session and sync ticket status, while `sessions` needed `escalation` to build the hand-off
|
||||
summary — resolved by making `EscalationService.buildSummary` a pure formatter with no
|
||||
repository/service dependencies of its own; `sessions` now owns ending its own session state
|
||||
and the ticket-status sync directly. (2) The `GET .../ai-session/actions` route initially lived
|
||||
in `tools` and imported `sessions` to resolve ticketId → session, which would have collided
|
||||
with `sessions`' own dependency on `tools` (for `proposeAndEvaluate`) — moved the route into
|
||||
`sessions` instead, which already owns that resolution; `tools` stays a clean leaf module with
|
||||
no dependency on `ai-support/sessions` at all.
|
||||
- **Found and fixed a real Prisma bug before it reached tests**: `AIConfidencePolicy.upsert`
|
||||
initially used Prisma's generated `productId_categoryId` compound-unique `where` shape, which
|
||||
rejects `null` for the (nullable) `categoryId` column at the client-API level ("Argument
|
||||
categoryId must not be null") even though the DB-level unique index itself permits it. Fixed by
|
||||
switching to `findFirst` + `update`/`create` instead of `upsert` — the same class of fix
|
||||
`KnowledgeRepository.updateCurrent` (004) already used for the same underlying Prisma
|
||||
limitation, discovered independently here.
|
||||
- **`ticket-state-machine.ts`'s AI_* statuses required two hooks into 003-ticketing's
|
||||
`tickets.service.ts`** to actually be driven correctly: (1) `createFromInboundRequest` enqueues
|
||||
the `AI_SESSION` job directly via `queueManager` (no import of `ai-support/sessions` — the
|
||||
worker, not the enqueue call, is what depends on it), and (2) `updateStatus` now publishes a
|
||||
`DomainEventName.TICKET_UPDATED` domain event unconditionally after every status change, using
|
||||
the event-bus scaffold (`src/events/`) that existed in this codebase from the original
|
||||
scaffold but had never been wired to anything — `ai-support/sessions` subscribes to it
|
||||
(registered in `src/events/handlers/index.ts`) to implement FR-023 (a human actor ends the AI
|
||||
session) without `tickets` ever needing to know `ai-support/sessions` exists.
|
||||
- **The runbook-matching convention is a real, disclosed scope decision, not an oversight**: a
|
||||
runbook's `key` is matched directly against the diagnosis's `problemType` string (no fuzzy
|
||||
matching, no separate mapping table) — admins author runbook keys to match the exact
|
||||
`problemType` vocabulary the AI's diagnosis call produces. This is simple and works, but is
|
||||
inherently a naming-convention contract between the diagnosis system prompt and runbook
|
||||
authoring, not a robust semantic match — documented in `session.service.ts`'s
|
||||
`enterTroubleshooting` and in research.md.
|
||||
- 9 unit tests (confidence-band, tool-policy-gate, runbook-step-advance) and 9 integration test
|
||||
files were added. The AI-independent ones (`ai-confidence-policy.test.ts`, the deterministic
|
||||
tool-policy-gate re-check in `ai-tools-and-runbook.test.ts`, and the message-routing guard in
|
||||
`ai-clarification.test.ts`) run unconditionally and were verified passing against a real
|
||||
Postgres/Redis/MinIO. The remaining integration tests and the two constitution-required
|
||||
standing E2E scenarios (`e2e-ai-flows.test.ts`) require a real `ANTHROPIC_API_KEY` and are
|
||||
gated with `describe.skipIf` so the suite skips them cleanly (not a failure) rather than
|
||||
requiring every contributor to hold a live credential just to run the test suite — they were
|
||||
written and confirmed to compile and skip correctly, but not yet run against a live model in
|
||||
this environment (no key was available this session). The "AI resolves directly" E2E test
|
||||
additionally exercises the resolution-guard transition deterministically (via
|
||||
`SessionsService.recheckVerification`, a new seam also intended for a future real
|
||||
product-signal webhook) rather than relying solely on live-model non-determinism to reach that
|
||||
state.
|
||||
- Full regression (all 17 pre-existing integration test files plus every new one) was run
|
||||
together against real Docker-provisioned Postgres/Redis/MinIO: 88 passed, 9 skipped (the
|
||||
AI-key-gated ones), 0 failed.
