Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

api-integration-specialist scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

API Integration Specialist

Build reliable integrations with clear auth, error handling, and rate limit safety.

Quick Start

  1. Read the provider’s auth + rate limit docs.
  2. Design a thin client with retries and typed errors.
  3. Transform provider payloads to internal models at the boundary.
  4. Add tests: happy path, auth failure, rate limit, and server error.

Integration Checklist

  • Auth: API key vs OAuth; store secrets in env; rotate safely.
  • Errors: map status codes to typed errors; include response body.
  • Retries: exponential backoff on 429/5xx; respect Retry-After.
  • Webhooks: verify signatures; idempotency; replay-safe handlers.
  • Pagination: cursor/offset; avoid unbounded loops.
  • Timeouts: set sane timeouts per call.

Boundary Pattern (example)

async function request(path, init) {
  const res = await fetch(`${baseUrl}${path}`, init);
  if (!res.ok) throw new ApiError(res.status, await res.json());
  return res.json();
}

Guardrails

  • Never log secrets.
  • Keep provider-specific logic at the boundary.
  • When requirements are unclear, ask for target SLAs and expected volume.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
