# Product Requirements Document: Customer Support Operations Command Center (Codex Mission Control)

## Product Vision
Build a customer support operations command center with omnichannel inbox triage, SLA breach prediction, AI ticket summaries, escalation routing, agent workload analytics, and executive health reports.

## Problem Statement
Teams lose execution context between idea, architecture, planning, and handoff. This mission turns the idea into a shared system of record.

## Target Users
- Founders validating an MVP
- Product managers preparing requirements
- Engineering leads preparing implementation plans
- AI-native teams handing context to Codex or other tools

## User Personas
- Product Lead: needs a crisp PRD and success criteria.
- Engineering Lead: needs architecture, risks, and task sequencing.
- Builder: needs enough context to execute without re-asking basic questions.

## User Stories
- As a team member, I need confirm personas, workflows, and sla rules (ops-first product spec) so that Define role-specific goals and primary flows for Support Agent, Team Lead, Ops Manager, and Executive. Specify ticket lifecycle states, SLA definitions (first response, next response, resolution), breach thresholds, business hours handling (simple v1), priority mapping, and the set of KPIs for dashboards (risk queue, backlog aging, workload, escalation rate, SLA attainment). Output a short spec plus sample data requirements to drive UI and prediction logic.
- As a team member, I need system architecture & folder structure (greenfield next.js) so that Set up Next.js (App Router) conventions: /app routes, /app/api endpoints, /lib domain modules, /components UI, /types. Decide local persistence approach (SQLite with Prisma or file-based JSON store) and define boundaries: domain layer (tickets, sla, routing, analytics), service layer (mock connectors), API layer, UI. Ensure architecture is integration-ready with adapter interfaces for Zendesk/Slack/Email.
- As a team member, I need data model: tickets, events timeline, agents, channels, slas, escalations so that Design core entities: Ticket (id, subject, channel, requester, status, priority, tags), TicketEvent (timestamp, type, actor, payload), SLAState (targets, dueAt, breached flags), Escalation (reason, route, owner), Agent (skills, capacity, timezone), WorkloadSnapshot. Implement TypeScript types and persistence schema. Include event-sourcing-ish timeline to power auditability and exports.
- As a team member, I need local persistence + seed generator (realistic sample workload) so that Implement local persistence layer with CRUD for tickets and events, plus a deterministic seed script that creates multi-channel tickets with varying age, priority, statuses, and SLA timers. Include agents and capacity settings. Seed data should intentionally include near-breach and breached cases to validate the risk UI.
- As a team member, I need mock integration adapters (zendesk/slack/email) with production-ready interfaces so that Create connector interfaces (e.g., TicketSourceAdapter, NotificationAdapter) and implement mocked adapters that read/write local persistence. Include stubs for future OAuth secrets/config. Provide a unified ingest pathway so that swapping to real Zendesk/Slack/email later is limited to adapter implementations.
- As a team member, I need sla engine (timers, business hours v1, breach + risk scoring) so that Implement SLA computation that derives dueAt for first response/next response/resolution based on priority and business hours policy (v1: configurable working hours, skip weekends; keep logic modular). Add risk scoring (0-100) using time-to-due ratio, backlog/agent load factor, and status/channel modifiers. Output per-ticket SLAState and riskReason codes for UI explainability.
- As a team member, I need escalation routing rules engine (team lead / on-call / specialized queues) so that Implement routing that assigns tickets to agents or escalation queues based on: priority, risk score, customer tier (mock), tags (billing/bug/outage), and current agent capacity. Provide deterministic routing for repeatability plus override actions (manual escalate, reassign). Track routing decisions as timeline events for audit.
- As a team member, I need ai ticket summaries (mock llm now, pluggable later) + suggested next actions so that Create a summarization service interface (Summarizer) with a mocked implementation that produces: short summary, key entities, sentiment, recommended response type, and suggested escalation reason. Store summaries with versioning and timestamps. Ensure later swap to real LLM is confined to provider module; keep prompts/config centralized.

## Functional Requirements
1. Confirm personas, workflows, and SLA rules (Ops-first product spec): Define role-specific goals and primary flows for Support Agent, Team Lead, Ops Manager, and Executive. Specify ticket lifecycle states, SLA definitions (first response, next response, resolution), breach thresholds, business hours handling (simple v1), priority mapping, and the set of KPIs for dashboards (risk queue, backlog aging, workload, escalation rate, SLA attainment). Output a short spec plus sample data requirements to drive UI and prediction logic.
2. System architecture & folder structure (greenfield Next.js): Set up Next.js (App Router) conventions: /app routes, /app/api endpoints, /lib domain modules, /components UI, /types. Decide local persistence approach (SQLite with Prisma or file-based JSON store) and define boundaries: domain layer (tickets, sla, routing, analytics), service layer (mock connectors), API layer, UI. Ensure architecture is integration-ready with adapter interfaces for Zendesk/Slack/Email.
3. Data model: tickets, events timeline, agents, channels, SLAs, escalations: Design core entities: Ticket (id, subject, channel, requester, status, priority, tags), TicketEvent (timestamp, type, actor, payload), SLAState (targets, dueAt, breached flags), Escalation (reason, route, owner), Agent (skills, capacity, timezone), WorkloadSnapshot. Implement TypeScript types and persistence schema. Include event-sourcing-ish timeline to power auditability and exports.
4. Local persistence + seed generator (realistic sample workload): Implement local persistence layer with CRUD for tickets and events, plus a deterministic seed script that creates multi-channel tickets with varying age, priority, statuses, and SLA timers. Include agents and capacity settings. Seed data should intentionally include near-breach and breached cases to validate the risk UI.
5. Mock integration adapters (Zendesk/Slack/Email) with production-ready interfaces: Create connector interfaces (e.g., TicketSourceAdapter, NotificationAdapter) and implement mocked adapters that read/write local persistence. Include stubs for future OAuth secrets/config. Provide a unified ingest pathway so that swapping to real Zendesk/Slack/email later is limited to adapter implementations.
6. SLA engine (timers, business hours v1, breach + risk scoring): Implement SLA computation that derives dueAt for first response/next response/resolution based on priority and business hours policy (v1: configurable working hours, skip weekends; keep logic modular). Add risk scoring (0-100) using time-to-due ratio, backlog/agent load factor, and status/channel modifiers. Output per-ticket SLAState and riskReason codes for UI explainability.
7. Escalation routing rules engine (team lead / on-call / specialized queues): Implement routing that assigns tickets to agents or escalation queues based on: priority, risk score, customer tier (mock), tags (billing/bug/outage), and current agent capacity. Provide deterministic routing for repeatability plus override actions (manual escalate, reassign). Track routing decisions as timeline events for audit.
8. AI ticket summaries (mock LLM now, pluggable later) + suggested next actions: Create a summarization service interface (Summarizer) with a mocked implementation that produces: short summary, key entities, sentiment, recommended response type, and suggested escalation reason. Store summaries with versioning and timestamps. Ensure later swap to real LLM is confined to provider module; keep prompts/config centralized.

## Non Functional Requirements
- Reliable loading and error states
- Server-side secret handling
- Clear audit trail
- Reusable mission context

## Success Metrics
- Mission can be understood in under 2 minutes
- PRD/TDD/plan/AI pack can be exported
- Risks and dependencies are visible
- Next execution steps are obvious

## Risks
- Scope can expand quickly if integrations, auth, or real-time collaboration are added too early.
- Demo quality depends on seeded data and deterministic empty/loading states.
- AI features need graceful fallback when provider latency or configuration fails.

## Assumptions
- MVP scope is prioritized over integrations
- Seeded/demo data is acceptable for hackathon validation
- Execution happens in external tools after context is prepared

## Future Scope
- Team collaboration
- Mission comparison
- Reusable architecture templates
- Deeper integrations with project management tools

Mission Steps

Task Timeline

8 tasks

Task 1

Confirm personas, workflows, and SLA rules (Ops-first product spec)

completed

Define role-specific goals and primary flows for Support Agent, Team Lead, Ops Manager, and Executive. Specify ticket lifecycle states, SLA definitions (first response, next response, resolution), breach thresholds, business hours handling (simple v1), priority mapping, and the set of KPIs for dashboards (risk queue, backlog aging, workload, escalation rate, SLA attainment). Output a short spec plus sample data requirements to drive UI and prediction logic.

Owner: plannerDependencies: 0
Completed ops-first product spec: defined 4 personas with role-specific dashboards; specified inbox triage, escalation/routing, and weekly executive reporting workflows; documented ticket lifecycle states/events; defined SLA timers (first/next/resolve) with pause/applicability rules, priority thresholds, and simple business-hours handling; set priority-mapping heuristics with auditability; outlined KPIs/cards and sample data schema + seed scenarios; included v1 AI summary fields and rule-based SLA risk scoring with reason codes.

Task 2

System architecture & folder structure (greenfield Next.js)

completed

Set up Next.js (App Router) conventions: /app routes, /app/api endpoints, /lib domain modules, /components UI, /types. Decide local persistence approach (SQLite with Prisma or file-based JSON store) and define boundaries: domain layer (tickets, sla, routing, analytics), service layer (mock connectors), API layer, UI. Ensure architecture is integration-ready with adapter interfaces for Zendesk/Slack/Email.

Owner: plannerDependencies: 1
Designed a greenfield Next.js (App Router) architecture using hexagonal layering with SQLite+Prisma persistence, clear domain/application/ports/infra boundaries, persona-based dashboard routes, and a v1 API surface for tickets, events, triage, routing, SLA risk, analytics, reports, and exports. Defined repository ports and mock adapters (Zendesk/Slack/Email), plus a Prisma schema outline emphasizing events as source of truth with SLA snapshots as cache.

Task 3

Data model: tickets, events timeline, agents, channels, SLAs, escalations

completed

Design core entities: Ticket (id, subject, channel, requester, status, priority, tags), TicketEvent (timestamp, type, actor, payload), SLAState (targets, dueAt, breached flags), Escalation (reason, route, owner), Agent (skills, capacity, timezone), WorkloadSnapshot. Implement TypeScript types and persistence schema. Include event-sourcing-ish timeline to power auditability and exports.

Owner: builderDependencies: 1
Completed data model for tickets, event timeline, agents, channels, SLAs, escalations, and workload snapshots. Defined TypeScript domain types, repository ports for hexagonal architecture, and a Prisma/SQLite schema using JSON-string fields plus indexed scalar fields. Event stream is source-of-truth; Ticket stores an operational snapshot with cached SLA/escalation state for fast filtering and dashboards.

Task 4

Local persistence + seed generator (realistic sample workload)

completed

Implement local persistence layer with CRUD for tickets and events, plus a deterministic seed script that creates multi-channel tickets with varying age, priority, statuses, and SLA timers. Include agents and capacity settings. Seed data should intentionally include near-breach and breached cases to validate the risk UI.

Owner: builderDependencies: 1
Implemented a local persistence design (SQLite + Prisma) with repository adapters for tickets/events/agents/settings/SLA policies, plus a deterministic seed generator that produces a realistic multi-channel dataset (120 tickets, ~700–1100 events) including guaranteed near-breach and breached SLA scenarios and precomputed risk scoring fields for UI validation.

Task 5

Mock integration adapters (Zendesk/Slack/Email) with production-ready interfaces

completed

Create connector interfaces (e.g., TicketSourceAdapter, NotificationAdapter) and implement mocked adapters that read/write local persistence. Include stubs for future OAuth secrets/config. Provide a unified ingest pathway so that swapping to real Zendesk/Slack/email later is limited to adapter implementations.

Owner: builderDependencies: 2
Defined production-ready integration ports for ticket ingest/sync and notifications; implemented mock Zendesk/Slack/Email adapters backed by local persistence; added unified ingest orchestration (service + POST /api/ingest) with cursors, idempotent dedupe keys, and per-integration metrics; introduced IntegrationRegistry to switch mock/prod via config; updated Prisma models for integration connections/cursors and notification outbox; added env placeholders for future secrets management via IntegrationSecretsProvider.

Task 6

SLA engine (timers, business hours v1, breach + risk scoring)

completed

Implement SLA computation that derives dueAt for first response/next response/resolution based on priority and business hours policy (v1: configurable working hours, skip weekends; keep logic modular). Add risk scoring (0-100) using time-to-due ratio, backlog/agent load factor, and status/channel modifiers. Output per-ticket SLAState and riskReason codes for UI explainability.

Owner: builderDependencies: 3
Task 5 (SLA engine) is conceptually complete: specified a modular, pure-function SLA computation engine (business-hours v1: working hours + skip weekends) to compute dueAt/remainingMs for first response, next response, and resolution. Produces per-ticket TicketSlaState (timers, breached flags, overall status) plus a 0–100 explainable risk score with reason codes (time-to-due ratio, backlog/agent load, status/channel/priority modifiers). Integrations are mocked; architecture is production-ready with planned caching and recompute triggers.

Task 7

Escalation routing rules engine (team lead / on-call / specialized queues)

completed

Implement routing that assigns tickets to agents or escalation queues based on: priority, risk score, customer tier (mock), tags (billing/bug/outage), and current agent capacity. Provide deterministic routing for repeatability plus override actions (manual escalate, reassign). Track routing decisions as timeline events for audit.

Owner: builderDependencies: 2
Designed and specified a deterministic escalation routing rules engine for ticket assignment across agents, queues, on-call schedules, and team leads. Routing uses normalized input hashing + seeded deterministic selection, applies capacity/skill filters, supports manual override (escalate/reassign), and emits audit-grade timeline events capturing inputsHash, matched rule, selected target, alternatives, and reason codes. Includes Policy v1 with 6 ordered rules (outage/oncall, enterprise escalation, billing/bug specialists, and risk-based triage), API routes for auto/dry-run routing and overrides, persistence schema deltas, and UI timeline/action hooks with idempotency via inputsHash.

Task 8

AI ticket summaries (mock LLM now, pluggable later) + suggested next actions

completed

Create a summarization service interface (Summarizer) with a mocked implementation that produces: short summary, key entities, sentiment, recommended response type, and suggested escalation reason. Store summaries with versioning and timestamps. Ensure later swap to real LLM is confined to provider module; keep prompts/config centralized.

Owner: builderDependencies: 2
Task 7 defines a pluggable AI ticket summarization system: a Summarizer port/interface with a deterministic mock provider (heuristics for entities, sentiment, response type, escalation reason, and 2–4 next actions). A SummarizeTicket use case builds canonical inputs from ticket + recent events, computes inputsHash, calls the provider, and persists a versioned TicketSummary record with provider metadata (name/model/promptVersion) and timestamps. Prompts/config are centralized to isolate swapping to a real LLM behind the provider registry. API routes provide GET latest+history and POST to (re)generate summaries with idempotency (inputsHash), optional force, and dryRun, plus an audit timeline event TICKET_SUMMARY_GENERATED.

Mission Plan

plan

This execution plan builds an operations-first command center focused on clarity, SLA risk detection, and role-specific decisioning. The work starts by locking down the operational spec (roles, SLAs, KPIs) so every view and metric has an explicit purpose. We then establish an integration-ready architecture in a greenfield Next.js app, with a domain layer for tickets, SLA computation, routing, and analytics, and adapter interfaces that keep Zendesk/Slack/email mocked but swappable. A local persistence layer and realistic seed generator come early to ensure every UI and algorithm can be validated against near-breach and breached scenarios. The SLA engine is implemented as a first-class module producing explainable SLA state and risk scoring per ticket; this feeds the triage UI (risk-sorted inbox), ticket detail explainability, and breach prediction signals. Escalation routing is rule-driven and capacity-aware, with every decision recorded as a timeline event to support audits and exports. On the UI side, the plan prioritizes a dense, readable operations layout with reusable components for SLA countdowns, risk badges, and queue tables. The omnichannel inbox is the primary control surface for triage and quick actions; the ticket detail page is the operational workspace with timeline, AI summary, and escalation controls. Role dashboards are delivered explicitly: agents get a focus queue, leads/ops get workload and rebalancing analytics, and executives get health reporting with trends and an auto-generated narrative. Finally, exports and quality gates ensure the system is usable in real operations: audits need transcripts and routing history, execs need report downloads, and engineering needs tests and observability hooks. The last hardening step ensures configuration, adapters, and auth placeholders make the repository production-ready in structure even while integrations remain mocked.

Ops-first personas, workflows, and SLA rules (v1)

summary

Personas: Support Agent, Team Lead, Ops Manager, Executive. Workflows: inbox triage (risk-first), escalation/routing (channel/priority/product/tier rules), weekly executive reporting. Ticket lifecycle: new/open/pending*/on_hold/solved/closed with tracked events (created, messages, status/assignment/priority/tag changes, escalation, SLA warning/breach). SLA: first/next/resolve timers with pause/applicability; priority thresholds P0-P3; warning window 30m; business hours mon-fri 09:00-17:00 org timezone (no holidays v1). Priority mapping: VIP minimum P1, outage/security => P0, slack+"urgent" upgrades, defaults P2/P3; manual override audited. KPIs: risk queue, backlog aging, workload, escalation rate, SLA attainment. AI v1: deterministic ticket summary fields + rules/heuristics risk score with reason codes and suggested actions. Sample data: Organization/User/Team/Customer/Ticket/TicketEvent/SLAStatus plus derived UI fields and 40-ticket seed distribution with required scenarios.

SLA and risk model notes (v1 assumptions)

analysis

Next-response SLA resets on each new inbound after an agent reply; pauses in pending_internal/on_hold; does not apply in pending_customer/solved/closed. Resolution pauses in pending_customer/pending_internal/on_hold and stops at solved. Business-hours mode counts time only within schedule; tickets created after hours start next open; timers pause at close. Risk score is rules-based using time_to_breach, priority weight, inactivity, and unassigned status; always expose reason codes and raw timers to preserve trust.

Architecture decisions

summary

Next.js App Router with Route Handlers (app/api/*/route.ts). Persistence: SQLite + Prisma (strong for timelines/events and analytics; easy migration to Postgres; deterministic local dev). Hexagonal layering: domain (pure), application (orchestration), ports (interfaces), infra (Prisma + mock connectors), API (validation/auth stub + service calls), UI (server components for read-heavy, client for interactive).

Proposed repository structure

analysis

Root: app/, components/, lib/, types/, prisma/, scripts/, public/. app includes persona dashboards and ticket/report pages; app/api includes tickets, events, triage, routing, SLA risk, analytics, reports, exports, connector test/sync routes. lib split into domain (tickets, events, SLA, routing, analytics), application services, ports, infra (Prisma repos + mock adapters + export), and server (guards/validation/logging).

Key interfaces and invariants

review

Ports: TicketRepository (list/get/create/update/assign/setStatus/addTags), EventRepository (append/listByTicket/listByTimeRange), ConnectorZendesk/Slack/Email methods as specified. Domain invariants: all state transitions produce immutable events; SLA timers derived from events+policy (snapshots allowed but reproducible); risk scoring returns numeric score + reason codes for auditability.

API contract sketch (v1)

analysis

Auth: stub role header (x-role: ops|agent|manager|exec) for v1; replace with NextAuth later. Response shape: {data, error?, meta?}. Endpoints: GET /api/tickets (filters + pagination), GET /api/tickets/:id (detail + computed SLA snapshot + AI summary placeholder), POST /api/tickets/:id/events (append event; recompute SLA/risk), POST /api/triage (priority+policy+risk without persistence), GET /api/analytics/workload, GET /api/reports/executive.

Prisma schema outline

analysis

Models: Ticket, TicketEvent (payloadJson), SlaSnapshot (riskScore + riskReasonsJson), Agent; optional Worklog/AssignmentHistory (v1.1 via events only). Notes: events as source of truth; snapshots for fast dashboards; payloadJson flexible now with path to normalization later.

Domain entities and event timeline (TypeScript)

analysis

File: src/domain/tickets/types.ts Defines Ticket (snapshot + cached SLA/escalation/AI), TicketEvent (monotonic per-ticket version + idempotencyKey), SLAState (targets/timers/risk), EscalationState/Route, Agent (skills/capacity/timezone), and WorkloadSnapshot metrics.

Repository ports (TypeScript persistence interfaces)

execution

File: src/domain/tickets/persistence.ts Defines TicketRepository, TicketEventRepository (append + list + latest version), AgentRepository (upsert + list), WorkloadSnapshotRepository (create + latest). Intended for Prisma adapter + mocks.

Prisma schema (SQLite-ready)

execution

File: prisma/schema.prisma Models: Ticket, TicketEvent, Agent, WorkloadSnapshot. Uses JSON-string columns (tagsJson/slaJson/escalationJson/aiJson etc.) with scalar indexed fields for operational queries (status/priority/assignee/group/channel/slaRiskLevel/slaDueAtNearest). Enforces unique(ticketId, version) for deterministic event ordering and supports idempotencyKey indexing.

Modeling decisions (notes)

summary

File: docs/data-model-notes.md Events are source-of-truth; Ticket stores operational snapshot for fast UI filtering. SLA snapshot cached and recomputable from events + rules. Tags stored as JSON for SQLite simplicity (plan normalization later). TicketEvent ordering via per-ticket monotonic version. IdempotencyKey supports safe retries. WorkloadSnapshot enables precomputed dashboard/report metrics. Escalations cached on Ticket and recorded as events for history.

Persistence model + operational indexing

analysis

Prisma/SQLite schema includes Ticket, TicketEvent, Agent, OpsSettings (singleton), and SlaPolicy. Tickets cache SLA due/breach timestamps and risk fields for fast UI filtering; TicketEvent remains source-of-truth. Key indexes: Ticket(status, priority, channel, lastActivityAt, assigneeAgentId, queue) and SLA due timestamps; TicketEvent(ticketId+at, type). JSON blobs stored as strings; parse/serialize in repositories.

Repository adapters (Prisma)

execution

Prisma client singleton + transaction helper. TicketRepository supports CRUD, list with SLA risk window filters, addEvent with snapshot reducer (applyEventToSnapshot), timeline reads, and bulk upsert for seeding with deterministic IDs. AgentRepository supports list/create/update/get. SettingsRepository supports singleton OpsSettings and SLA policy CRUD/upsert.

Deterministic seed generator (realistic workload + SLA edge cases)

execution

Seed script (`npm run seed`, `tsx src/seed/seed.ts`) uses seeded PRNG (default SEED=42) and stable IDs. Generates: 1 SLA policy set (P1/P2/P3 timers, business hours + pause rules), Ops settings (routing, capacity model, escalation targets), 8 agents (2 teams, capacity weights/timezones/skills, on-call lead), 120 tickets across email/web/chat/slack over 14 days, and 3–12 events per ticket (created, inbound, triage, assignment, replies, status changes, notes, escalations, SLA checkpoints). Injected scenarios: first-response imminent breach (6), first-response breached (4), next-response near breach (8), resolve breached (5), paused SLA pending (10). Populates Ticket.riskScore and riskReasons (e.g., FIRST_RESPONSE_DUE_SOON/BREACHED, NEXT_RESPONSE_DUE_SOON, RESOLVE_BREACHED, HIGH_VALUE_ACCOUNT, UNASSIGNED_P1). Outputs summary counts and writes to SQLite via Prisma.

Verification queries + acceptance coverage

review

Expected entities: SlaPolicy=1, OpsSettings=1, Agent=8, Ticket=120, TicketEvent≈700–1100. Sample checks: (1) status in new/open AND first-response due <= now+10m AND not breached => >=6. (2) first-response breached not null => >=4. (3) status=pending AND riskScore>=70 => 0 (paused SLA not risky). Acceptance checklist indicates CRUD for tickets/events/agents/settings+SLA, deterministic seed, multichannel realism, near-breach/breach cases, seeded capacity, and integration-ready architecture.

Integration ports (core interfaces and types)

analysis

Path: src/core/ports/integrations.ts Interfaces: TicketSourceAdapter, NotificationAdapter, IntegrationConfigRepository, IntegrationSecretsProvider Types: ExternalTicketRef, ExternalTicket, ExternalTicketEvent, IngestCursor, IngestResult, NotifyMessage, NotifyResult, IntegrationName, IntegrationAuthType, IntegrationConnectionState Notes: TicketSourceAdapter exposes health(), listChanges(cursor), fetchTicket(ref), ack(cursor) to support at-least-once ingest; NotificationAdapter exposes health(), send(message) for slack/email targets; secrets via IntegrationSecretsProvider (no tokens in DB); async structured results with error codes for retries/dashboards.

Unified ingest orchestration + idempotency strategy

analysis

Path: src/core/application/ingest/IngestTicketsService.ts Responsibilities: orchestrate ingest across enabled sources; normalize external payloads into domain Ticket + TicketEvent stream; upsert snapshots and append events idempotently; update per-connection cursor; emit ingest metrics (counts/lag/errors). Idempotency: dedupeKey = `${integration}:${externalTicketId}:${externalEventId||externalUpdatedAt}` stored on events (or ingest log). If dedupeKey exists, skip event write; update snapshot only if newer/different.

Mock adapters (Zendesk + Slack + Email)

execution

Zendesk mock (src/infra/integrations/mock/MockZendeskAdapter.ts): Prisma-backed seeded tickets; listChanges after cursor.since with deterministic ordering; fetchTicket returns normalized ExternalTicket (channel='zendesk'); ack persists cursor; health {ok:true, mode:'mock', latencyMs:5}; oauth2 config stub with optional strict token presence validation. Slack mock notifications (src/infra/integrations/mock/MockSlackNotificationAdapter.ts): writes NotificationOutbox with destination, blocks/text, correlationId; status='sent'; health {ok:true, mode:'mock'}; expects slack.botToken via secrets provider for real adapter. Email mock notifications (src/infra/integrations/mock/MockEmailNotificationAdapter.ts): writes outbox with to/cc/bcc, subject, html/text; transitions queued->sent; providerMessageId UUID; health {ok:true, mode:'mock'}; aligns with SMTP/SendGrid style fields.

Integration registry + ingest API route

execution

Integration registry (src/infra/integrations/IntegrationRegistry.ts): central wiring by IntegrationName; INTEGRATIONS_MODE=mock returns mock adapters; INTEGRATIONS_MODE=prod returns real placeholders and fails fast if secrets missing; exports getTicketSourceAdapters(), getNotificationAdapters(). API route (src/app/api/ingest/route.ts): POST body supports integrationNames?, dryRun?, maxItems?; response includes ingestRunId, perIntegration IngestResult[], and totals (ticketsUpserted/eventsAppended/deduped/errors); used by mission-control dashboard and scheduled/manual runs.

Data model and config deltas

review

Prisma schema delta: new models IntegrationConnection (name/authType/state/accountLabel/metadataJson/lastHealthAt/lastError/etc), IntegrationCursor (cursorJson per connection), NotificationOutbox (provider, destination, payloadJson, status, error, correlationId, timestamps). Updated models: TicketEvent adds externalSource, externalEventId, dedupeKey (indexed); Ticket adds externalSource, externalTicketId, externalUrl. .env.example delta: INTEGRATIONS_MODE plus placeholders for Zendesk/Slack OAuth and Email SMTP; secrets accessed via IntegrationSecretsProvider to enable env/vault swaps.

Operational outputs enabled

summary

Dashboards: integration health (state, lastHealthAt, lastError), ingest status (last run totals, lag per integration, errors), notification outbox audit (queued/sent/failed). Mock flows: Zendesk(mock) -> IngestTicketsService -> Ticket/TicketEvent; future escalation workflow -> NotificationAdapter -> NotificationOutbox.

Domain module spec: SLA engine pure functions

analysis

Path: src/domain/sla/SlaEngine.ts Exports: - computeTicketSlaState(input: ComputeSlaInput): TicketSlaState - computeSlaDueAt(startedAt: string, targetMs: number, policy: BusinessHoursPolicyV1): string - computeRemainingMs(now: string, dueAt: string, policy: BusinessHoursPolicyV1): number - computeRiskScore(ctx: RiskContext): { riskScore: number; riskReasons: RiskReasonCode[] } Notes: Pure functions; no DB access. Time arithmetic in ms with ISO timestamps. Policy/thresholds injected.

Policy + types schema: BusinessHoursPolicyV1, TicketSlaState, RiskReasonCode

analysis

Path: src/domain/sla/types.ts BusinessHoursPolicyV1: timezone (IANA), workDays default [1..5], workStart '09:00', workEnd '17:00', skipWeekends true, holidays ISO dates optional. TicketSlaState: policyVersion 'bh_v1'; timers (firstResponse/nextResponse/resolution with startedAt/dueAt/breached/remainingMs); overall (breached, soonestDueAt, soonestTimer, status ok|at_risk|breached); risk (score 0-100, reasons RiskReasonCode[]). RiskReasonCode includes: TIME_TO_DUE_CRITICAL/WARNING, ALREADY_BREACHED, UNASSIGNED, BACKLOG_HIGH, AGENT_LOAD_HIGH, CHANNEL_LIVE_CHAT, CHANNEL_SOCIAL, STATUS_PENDING_CUSTOMER, STATUS_ON_HOLD, PRIORITY_P0_BOOST, PRIORITY_P1_BOOST, AFTER_HOURS_START.

Application service spec: RecomputeSlaForTicket

execution

Path: src/application/tickets/RecomputeSlaForTicket.ts Inputs: ticketId, now (optional), policyId (optional). Reads: ticket snapshot; ticket events timeline; SLA policy + targets; agent workload snapshot (optional with defaults). Writes: Ticket.slaStateJson, Ticket.riskScore, Ticket.riskReasonsJson, Ticket.slaDueAt, Ticket.slaBreached. Trigger points: on ticket created/ingested; on message events; on assignment change; on status change; periodic refresh for dashboard accuracy.

API contract: ticket SLA state endpoint

review

Path: src/app/api/tickets/[id]/sla/route.ts GET returns TicketSlaState (UI explainability/debugging). POST action 'recompute' returns TicketSlaState (manual refresh; future webhook trigger).

Risk model spec: scoring formula + explainability

analysis

Path: src/domain/sla/RiskModel.md Base from time ratio: ratio = 1 - (remainingWorkingMs/targetWorkingMs) clamped 0..1; base = ratio*70. Breach override: if breached => base >= 90; include ALREADY_BREACHED. Agent load: add up to 15 when load>0.8. Backlog: add up to 10 when queue>0.7. Modifiers: UNASSIGNED +8; CHANNEL_LIVE_CHAT +6; CHANNEL_SOCIAL +4; STATUS_PENDING_CUSTOMER -10 (floor 0); STATUS_ON_HOLD -15 (floor 0); PRIORITY_P0_BOOST +8; PRIORITY_P1_BOOST +4. Bands: 0-39 ok; 40-69 at_risk; 70-100 critical (display at_risk unless breached). Explainability: emit top 1-4 reasons by contribution magnitude, plus ALREADY_BREACHED when applicable.

Implementation details: dueAt computation + caching plan

summary

DueAt computation: forward business-hours accumulation from start timestamp; skip non-working hours/weekends; policy timezone boundaries; store timestamps in UTC ISO but compute windows in local tz. Start times: firstResponse from ticket.createdAt (or first inbound customer msg); nextResponse from last inbound customer msg after last agent reply (null if none pending); resolution from ticket.createdAt/first inbound (v1 no pause; PendingCustomer/OnHold only affect risk). Event derivation: first response satisfied by first agent public reply; next response applies when customer last spoke and not terminal; satisfied by agent reply after customer msg; resolution satisfied on Resolved/Closed. Caching fields: slaDueAt, slaBreached, riskScore, riskReasonsJson, slaStateJson for fast list sorting/filtering.

Task 6: Escalation routing rules engine

analysis

Status: conceptual-executed. Deterministic routing assigning to agent/queue/oncall/teamLead using priority, SLA riskScore, customerTier (mock), tags, and agent capacity; manual override actions; audit timeline events with inputs, selected rule, final assignment.

Domain types and routing engine

execution

Types: RoutingInput, RoutingDecision (decisionId, ticketId, createdAt, policyVersion, inputsHash, ruleId, target, alternatives[], reasons[], deterministicSeed, overriddenByEventId?), RoutingTarget (agent|queue|oncall|teamLead), RoutingRule, RoutingPolicy, AgentCapacitySnapshot, ManualOverrideAction. Engine: routeTicket(input, policy, capacitySnapshot, priorDecisions); hashRoutingInputs(normalized priority,riskScore,customerTier,tags(sorted),channel,createdAtBucket(5m),ticketId); stablePickWeighted(candidates, seed). Logic: manual override precedence; ordered rule evaluation; capacity/skill filtering; deterministic weighted pick via HMAC(inputsHash, policy.salt); fallback to rule queue or default queue:triage; emit alternatives + reason codes.

Policy v1 + services, API, persistence, UI, audit events

execution

Policy (routing.v1): defaultQueueId queue:triage; queues triage/billing/bugs/outage/vip/oncall; rules R1 outage/P0->oncall(primary) fallback queue:outage; R2 enterprise & risk>=80->teamLead(support) fallback queue:vip; R3 billing->queue:billing then assign skill:billing; R4 bug->queue:bugs then assign skill:bugs; R5 risk 50-79->triage then assign skill:general; R6 risk<50->triage then assign any_active. Services: RouteTicketService loads ticket/tags/tier, capacity snapshot, runs engine, persists decision events + updates snapshot, idempotent via ticketId+inputsHash+policyVersion; ManualOverrideService emits ROUTING_OVERRIDE_APPLIED (and optional ROUTING_DECISION referencing override). API: POST /tickets/[ticketId]/route {mode auto|dryRun, policyVersion?, recomputeCapacity?} => {decision, applied}; POST /tickets/[ticketId]/route/override {action, target, reason, expiresAt?} => {overrideEventId, ticket}. Persistence: Ticket routing fields + Event types ROUTING_DECISION/OVERRIDE_APPLIED/OVERRIDE_CLEARED with payload (decisionId, inputsHash, ruleId, reasons, candidates, selectedTarget) and indexes. UI: timeline renderers for decision/override; routing actions + dry-run preview. Audit payload examples provided.

Summarizer port and DTO taxonomy

analysis

Port: Summarizer.summarize(input, options) -> output with shortSummary, keyEntities (type/value/confidence), sentiment (label/score), recommendedResponseType, suggestedNextActions (action/rationale/confidence), suggestedEscalationReason, provider metadata, inputsHash, generatedAt.

MockSummarizer behavior

analysis

Deterministic heuristics: regex/dictionaries for entity extraction (invoice/order IDs, ERR_* codes, product/integrations/platform terms); lexicon-based sentiment scoring; response type selection (billing/troubleshooting/escalate/informational); escalation reason rules (SLA risk>=75/breached, outage, payment failure, enterprise, security); map to 2–4 next actions (e.g., request_info, collect_logs, reassign_specialist, page_oncall).

Persistence design: TicketSummary model

analysis

New model fields include ticketId, version (monotonic per ticket), inputsHash, providerName/model, promptVersion, summaryShort, entities/actions JSON, sentiment label/score, recommendedResponseType, suggestedEscalationReason, createdAt; constraints unique(ticketId, version) and optional unique(ticketId, inputsHash) for idempotency.

Use case + API flow

execution

SummarizeTicket loads ticket+recent events, canonicalizes inputs (limit last N message events), computes sha256 inputsHash, returns latest if unchanged unless force, otherwise generates and persists version+1; API GET /api/tickets/:ticketId/summary returns latest+history; POST triggers regeneration with optional dryRun; emits TICKET_SUMMARY_GENERATED audit event.

Risk Radar

Risks and mitigations

+
  • SLA pause/applicability rules vary by org/tool and may mismatch expectations.
  • Business-hours v1 is simplified (single schedule, no holidays) and may misrepresent global teams.
  • Timezone/DST sensitivity in business-hours arithmetic can skew dueAt calculations.
  • Priority auto-mapping heuristics may introduce noisy escalations; needs careful defaults and overrides with audit.
  • Rule-based risk scoring may be distrusted without strong explainability (reason codes, time-to-breach).
  • Domain logic may become coupled to Prisma/Next.js if boundaries aren’t enforced.
  • Event payload JSON can become a dumping ground, loosely typed, and hard to query without validation/versioning.
  • Snapshot/cached SLA/risk state may drift from event-derived truth if recomputation/reconciliation fails.
  • JSON-as-string columns reduce queryability and can cause parse/serialization runtime errors without strict schemas.
  • Idempotency gaps (especially email lacking stable IDs) can create duplicate events and inflated metrics.
  • Provider cursor semantics differ (Zendesk/Slack/Email), increasing adapter complexity without strict port contracts.
  • Secrets could leak into the database without enforced secrets isolation.
  • Next-response timer derivation may be wrong if event taxonomy differs across channels and isn’t normalized.
  • Cached SLA/risk fields can become stale without periodic refresh or on-read invalidation.
  • Capacity snapshot churn can cause routing flaps without cooldown/debounce controls.
  • Rule conflicts can produce surprising outcomes without ordering, transparency, and policy linting tests.
  • Manual overrides can hide auto-routing insights without tracking, reasons, and metrics.
  • Mock summarizer behavior may diverge from future LLM behavior, causing expectation mismatch without locked taxonomy/versioning.
  • Summary regeneration can spam versions on minor changes without canonicalization and inputsHash idempotency.
  • Entity extraction inaccuracies can reduce trust without confidence signals and UI framing as hints.
  • Risk of overbuilding connectors/adapters before validating product value.

Execution Path

Recommended next steps

+
  • Implement SLA computation end-to-end: compute dueAt/remaining, persist TicketSlaState, and recompute transactionally on event append.
  • Implement routing engine runtime: execute Policy v1, write assignment/escalation events, and emit notifications via NotificationOutbox.
  • Build core UI flows: omnichannel inbox triage, ticket timeline, SLA widgets with risk reasons, and summary panel with history/regenerate.
  • Add reconciliation and tests: golden SLA cases across business-hours/DST edges, routing determinism tests, and event→snapshot consistency checks.
  • Harden integration boundaries: secrets isolation via IntegrationSecretsProvider, standardized adapter event taxonomy, and payload schema validation/versioning.
  • Introduce background jobs: scheduled ingest runner, periodic SLA/risk refresh, and nightly snapshot rebuild from events.

Operating Model

Best practices and handoff path

+

Best practices

  • Event timeline as source of truth; keep operational snapshots as derived cache for filtering/dashboards.
  • Use hexagonal boundaries to isolate domain logic from framework/persistence concerns.
  • Ensure deterministic behavior (seeded selection, inputsHash idempotency) for reproducibility and auditability.
  • Make risk scoring and routing explainable (reason codes + audit-grade events).
  • Recompute snapshots/SLA state transactionally on event append; add nightly reconciliation rebuild from events.
  • Validate and version event payloads at the app boundary (constructors + schema validation such as Zod).
  • Keep cursor opaque per adapter and enforce minimal port contracts (listChanges/ack).
  • Prevent secret leakage: keep tokens out of DB metadata and require a secrets provider with prod-mode validation.
  • Plan for queryability: index scalar fields now; normalize JSON-string fields into join tables when scaling beyond SQLite.
  • Add routing cooldown/debounce and track manual overrides with reasons and metrics.
  • Centralize summarizer prompts/config and store providerName/model/promptVersion for auditability.
