What it does

Appfolio Local Dev Loop is an agent skill from jeremylongshore/tons-of-skills-marketplace. Set up local development for AppFolio property management API integration. Trigger: "appfolio local dev".

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Designed for Claude Code

It sits in Backend & APIs, covering Real estate and Third-party API integration. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Tasks that involve Real estate
  • Tasks that involve Third-party API integration

Example prompts

  • “appfolio local dev”
  • “/appfolio-local-dev-loop”

Requirements

  • Node.js
  • 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. Run the local server only in mock mode and exercise reads/writes against
  2. Test request validation, idempotency, redaction, and error handling in unit
  3. Run the sandbox lane separately with the contract-bound managed client and
  4. Stop when the fixture, credentials, request budget, or output redaction is

What it can do on your machine

Read from SKILL.md and the folder at commit 80f86df. 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

    Shell commands in SKILL.md call:

    • npm

    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 Local Dev Loop loads about 1.5k tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 455 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:49
    cp .env.example .env

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 Local Dev Loop

Overview

Local development workflow for AppFolio property management API integration. Provides a fast feedback loop with mock property, tenant, and lease endpoints so you can build and test integrations without consuming live API quota. Toggle between mock mode for rapid iteration and sandbox mode for pre-deployment validation against the real AppFolio Stack API.

Prerequisites

  • A mock-only local environment with synthetic property, tenant, lease, and work-order fixtures that contain no production addresses, names, or payments.
  • A separately managed sandbox credential and an approved safe-read fixture for the dedicated integration lane; it is never loaded by the local dev server.
  • A log policy that records request shape and status only, plus an explicit owner for sandbox quota, fixture reset, and credential rotation.

Instructions

  1. Run the local server only in mock mode and exercise reads/writes against synthetic routes with deterministic fixtures.
  2. Test request validation, idempotency, redaction, and error handling in unit tests before any sandbox connectivity check.
  3. Run the sandbox lane separately with the contract-bound managed client and one authorized safe-read fixture; do not turn a local proxy into a live API tunnel.
  4. Stop when the fixture, credentials, request budget, or output redaction is unverified, then correct the environment before continuing.

Environment Setup

bash
cp .env.example .env
# Leave provider credentials blank locally. Mock mode is the default.
# MOCK_MODE=true
npm install express axios dotenv tsx typescript @types/node
npm install -D vitest supertest @types/express

Dev Server

typescript
// src/dev/server.ts
import express from "express";
const app = express();
app.use(express.json());
const MOCK = process.env.MOCK_MODE === "true";
if (!MOCK) throw new Error("Local server is mock-only; use the managed sandbox integration lane");
const { mountMockRoutes } = require("./mocks");
mountMockRoutes(app);
app.listen(3001, () => console.log(`AppFolio dev server on :3001 [mock=${MOCK}]`));

Mock Mode

typescript
// src/dev/mocks.ts — realistic property management responses
export function mountMockRoutes(app: any) {
  app.get("/api/v1/properties", (_req: any, res: any) => res.json([
    { id: "prop_1", name: "Sunset Apartments", address: { street: "123 Sunset Blvd", city: "Los Angeles", state: "CA" }, property_type: "residential", unit_count: 24 },
    { id: "prop_2", name: "Downtown Office", address: { street: "456 Main St", city: "San Francisco", state: "CA" }, property_type: "commercial", unit_count: 8 },
  ]));
  app.get("/api/v1/tenants", (_req: any, res: any) => res.json([
    { id: "t1", first_name: "Jane", last_name: "Smith", email: "jane@example.com", unit_id: "u1", lease_id: "l1" },
  ]));
  app.get("/api/v1/leases", (_req: any, res: any) => res.json([
    { id: "l1", unit_id: "u1", start_date: "2025-01-01", end_date: "2026-01-01", rent_amount: 2500, status: "active" },
  ]));
  app.post("/api/v1/work-orders", (req: any, res: any) => res.status(201).json({ id: "wo_1", ...req.body, status: "open" }));
}

Testing Workflow

bash
npm run dev:mock &                    # Start mock server in background
npm run test                          # Unit tests with vitest
npm run test -- --watch               # Watch mode for rapid iteration
npm run test:sandbox                     # Managed, read-only sandbox lane

Debug Tips

  • Set DEBUG=express:* to trace all route matching and middleware execution
  • Use local test assertions for fixture counts and schema shape, not raw tenant payload dumps
  • Check X-RateLimit-Remaining header when testing against the live API
  • AppFolio sandbox returns 403 for properties you do not own — verify your API key scope
  • Use interceptors only for redacted endpoint/status/count telemetry during development

Output

  • A deterministic mock-only local server with synthetic property-management fixtures and no provider credential dependency
  • Unit-test evidence for validation, idempotency, and PII-safe observability
  • A separate managed sandbox result containing only redacted safe-read status

Examples

For a work-order UI change, add a synthetic mock fixture and test the request schema plus duplicate-submission behavior locally. Assert the returned ID and status without emitting the request body or tenant record. After unit tests pass, run the dedicated sandbox lane against one approved safe-read fixture. If mock mode is disabled, a sandbox credential appears locally, or a response contains unredacted tenant fields, stop the run and restore the local boundary.
