When your agent uses it

  • Tasks that involve Real estate
  • Tasks that involve Accounting and bookkeeping

Example prompts

  • “appfolio architecture”
  • “/appfolio-reference-architecture”

Requirements

  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash(npm:*), Bash(curl:*), Grep

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Build the contract-bound client and safe-read service layer first, with
  2. Enable provider events only after the contract and durable raw-body,
  3. Persist an idempotency/reconciliation record before any work-order,
  4. Validate the architecture in staging with synthetic data, a forced provider

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Bash(npm:*)
    • Bash(curl:*)
    • Grep

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • appfolio.com
    • engineering.appfolio.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Appfolio Reference Architecture loads about 1.9k tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 498 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

AppFolio Reference Architecture

Overview

Production architecture for property management integrations with the AppFolio Stack API. Designed for multi-property portfolios requiring real-time vacancy tracking, tenant lifecycle management, work order routing, and accounting reconciliation. Key design drivers: data freshness for leasing decisions, idempotent sync for financial accuracy, and tenant-facing portal responsiveness.

Prerequisites

  • A provider-verified contract for endpoints, authentication, events (if any), rate limits, data residency, and permitted downstream accounting/CRM effects.
  • Separate staging and production environments with managed secrets, synthetic fixtures, durable queues/idempotency stores, and named reconciliation owners.
  • Data classification that limits dashboard and cache models to the smallest permitted fields; tenant contact, payment, and balance data require separate encrypted stores and access controls.

Instructions

  1. Build the contract-bound client and safe-read service layer first, with endpoint budgets, minimized cache entries, and observability before adding write or event processing.
  2. Enable provider events only after the contract and durable raw-body, signature, persistence, and replay boundaries have been proven; otherwise use bounded incremental reconciliation.
  3. Persist an idempotency/reconciliation record before any work-order, accounting, tenant, or lease mutation and require explicit authorization.
  4. Validate the architecture in staging with synthetic data, a forced provider failure, duplicate event/retry, and rollback rehearsal before promotion.

                      Accounting Sync ──→ QuickBooks/Xero

* Use provider events only when the active contract confirms their delivery and security semantics; otherwise feed the queue from bounded reconciliation.

Service Layer

typescript
class PropertyService {
  constructor(private client: AppFolioClient, private cache: CacheLayer) {}

  async getPortfolioSummary(propertyIds: string[]): Promise<PortfolioSummary> {
    const properties = await Promise.all(
      propertyIds.map(id => this.cache.getOrFetch(`prop:${id}`, () => this.client.get(`/properties/${id}`)))
    );
    return { totalUnits: properties.reduce((sum, p) => sum + p.units.length, 0),
             vacancyRate: this.calcVacancy(properties), pendingWorkOrders: await this.getPendingOrders(propertyIds) };
  }

  async routeWorkOrder(order: WorkOrderRequest): Promise<string> {
    const property = await this.client.get(`/properties/${order.propertyId}`);
    const vendor = this.selectVendor(property.region, order.category);
    return this.client.post('/work-orders', { ...order, assigned_vendor: vendor });
  }
}

Caching Strategy

typescript
const CACHE_CONFIG = {
  properties: { ttl: 300, prefix: 'prop' },     // 5 min — changes infrequently
  tenants:    { ttl: 120, prefix: 'tenant' },    // 2 min — moderate churn
  leases:     { ttl: 60,  prefix: 'lease' },     // 1 min — financial accuracy
  workOrders: { ttl: 30,  prefix: 'wo' },        // 30s — real-time tracking
  vacancies:  { ttl: 15,  prefix: 'vacancy' },   // 15s — leasing speed matters
};
// Webhook-driven invalidation: AppFolio events flush matching cache keys immediately

Event Pipeline

typescript
class PropertyEventPipeline {
  private queue = new Bull('appfolio-events', { redis: process.env.REDIS_URL });

  async onWebhook(event: AppFolioEvent): Promise<void> {
    await this.queue.add(event.type, event, { attempts: 3, backoff: { type: 'exponential', delay: 2000 } });
  }

  async processLeaseEvent(event: LeaseEvent): Promise<void> {
    if (event.type === 'lease.signed') await this.updateVacancy(event.propertyId);
    if (event.type === 'lease.terminated') await this.triggerMoveOutWorkflow(event);
  }

  async processWorkOrderEvent(event: WorkOrderEvent): Promise<void> {
    if (event.status === 'completed') await this.reconcileVendorInvoice(event);
  }
}

Data Model

typescript
interface Property { id: string; name: string; address: Address; units: Unit[]; region: string; }
interface TenantRef { id: string; leaseId: string; contactCiphertextRef: string; }
interface Lease    { id: string; propertyId: string; unitId: string; tenantId: string; startDate: string; endDate: string; monthlyRent: number; status: 'active' | 'pending' | 'terminated'; }
interface WorkOrder { id: string; propertyId: string; unitId: string; category: 'plumbing' | 'electrical' | 'hvac' | 'general'; status: string; assignedVendor: string; }

Scaling Considerations

  • Partition sync workers by property region to avoid cross-region API rate limits
  • Use read replicas for dashboard queries; write path goes through event pipeline
  • Batch tenant notifications (rent reminders, maintenance updates) via queue to avoid email rate limits
  • Cache vacancy data aggressively — leasing agents hit this endpoint 10x more than any other
  • Shard work order routing by property portfolio to enable independent scaling per management group

Error Handling

ComponentFailure ModeRecovery
Property syncAppFolio 429 rate limitExponential backoff with jitter, per-property circuit breaker
Lease webhookDuplicate event deliveryIdempotency key on lease ID + event timestamp
Work order routingVendor API timeoutQueue retry with fallback to manual assignment
Accounting syncBalance mismatchReconciliation queue with human review flag
Tenant portalCache miss stormStale-while-revalidate pattern, circuit breaker on API layer

Output

  • A contract-bound, staged architecture with service, cache, queue, data, and reconciliation ownership explicitly separated
  • Minimized dashboard references and encrypted/controlled boundaries for tenant contact, payment, and balance data
  • A deployment decision supported by staging failure, duplicate/replay, rate, rollback, and reconciliation evidence

Examples

For a vacancy-dashboard rollout, start with synthetic property and unit IDs, one bounded safe-read, and a cache that exposes data age. Inject a duplicate event or reconciliation record, a 429, and a downstream accounting timeout to prove the queue and idempotency store prevent duplicate effects. Promote only when results remain complete and authorized and the rollback/reconciliation owners can demonstrate their paths. If event support, data classification, durable state, or a write outcome is unverified, keep the corresponding path disabled and use operator-led reconciliation.
