What it does

Fondo Rate Limits is an agent skill from jeremylongshore/tons-of-skills-marketplace. Manage rate limits for Fondo-connected services including Gusto API, QuickBooks API, Plaid, and Stripe when building parallel integrations. Trigger: "fondo rate limit", "gusto API limits", "QuickBooks throttling".

Its SKILL.md is about 1.4k 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 Rate limiting. It works with QuickBooks and Stripe. 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 Rate limiting

Example prompts

  • “fondo rate limit”
  • “gusto API limits”
  • “QuickBooks throttling”
  • “/fondo-rate-limits”

Requirements

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

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

    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):

    • docs.gusto.com
    • developer.intuit.com
    • stripe.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

Fondo Rate Limits loads about 1.4k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 305 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

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.

Fondo Rate Limits

Prerequisites

Confirmed provider limits, an approved concurrency/retry policy, opaque queue telemetry, a finance owner, and synthetic test workload.

Instructions

Honor throttle signals, use bounded backoff and idempotency, route exhausted work to reviewed handling, and reduce load before resuming.

Output

Publish a rate-control receipt with policy version, aggregate throttles, queue outcome, owner, and manual disposition—never financial payloads or credentials.

Examples

Simulate a throttle for a fictional export, verify the retry runs once under its operation ID, and send repeated failure to review without exposing records.

Overview

Fondo itself is a managed tax and accounting service without direct API rate limits, but startups building parallel integrations to the same financial providers Fondo connects to (Gusto, QuickBooks, Plaid, Stripe, Mercury) must coordinate their own API calls to avoid shared-limit conflicts. During Fondo's nightly sync windows, your direct API calls compete for the same provider quotas, making careful scheduling and throttling critical for tax-season workloads and month-end reconciliation batches.

Rate Limiter Implementation

typescript
class MultiProviderLimiter {
  private limiters: Map<string, { tokens: number; max: number; lastRefill: number; rate: number }> = new Map();

  register(provider: string, maxPerMinute: number) {
    this.limiters.set(provider, {
      tokens: maxPerMinute, max: maxPerMinute,
      lastRefill: Date.now(), rate: maxPerMinute / 60_000,
    });
  }

  async acquire(provider: string): Promise<void> {
    const l = this.limiters.get(provider);
    if (!l) throw new Error(`Unknown provider: ${provider}`);
    const now = Date.now();
    l.tokens = Math.min(l.max, l.tokens + (now - l.lastRefill) * l.rate);
    l.lastRefill = now;
    if (l.tokens >= 1) { l.tokens -= 1; return; }
    const waitMs = (1 - l.tokens) / l.rate;
    await new Promise(r => setTimeout(r, waitMs));
    l.tokens = 0;
  }
}

const limiter = new MultiProviderLimiter();
limiter.register("gusto", 40);      // 40/min leaves room for Fondo syncs
limiter.register("quickbooks", 400); // buffer under 500/min
limiter.register("plaid", 80);

Retry Strategy

typescript
async function providerRetry<T>(
  provider: string, fn: () => Promise<Response>, maxRetries = 3
): Promise<T> {
  for (let attempt = 0; attempt <= maxRetries; attempt++) {
    await limiter.acquire(provider);
    const res = await fn();
    if (res.ok) return res.json();
    if (res.status === 429) {
      const retryAfter = parseInt(res.headers.get("Retry-After") || "15", 10);
      const jitter = Math.random() * 3000;
      await new Promise(r => setTimeout(r, retryAfter * 1000 + jitter));
      continue;
    }
    if (res.status >= 500 && attempt < maxRetries) {
      await new Promise(r => setTimeout(r, Math.pow(2, attempt) * 2000));
      continue;
    }
    throw new Error(`${provider} API ${res.status}: ${await res.text()}`);
  }
  throw new Error("Max retries exceeded");
}

Batch Processing

typescript
async function batchReconcile(transactions: any[], provider: string, batchSize = 15) {
  const results: any[] = [];
  for (let i = 0; i < transactions.length; i += batchSize) {
    const batch = transactions.slice(i, i + batchSize);
    const batchResults = await Promise.all(
      batch.map(txn => providerRetry(provider, () =>
        fetch(`${PROVIDER_URLS[provider]}/transactions`, {
          method: "POST", headers: providerHeaders[provider],
          body: JSON.stringify(txn),
        })
      ))
    );
    results.push(...batchResults);
    if (i + batchSize < transactions.length) await new Promise(r => setTimeout(r, 5000));
  }
  return results;
}
