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

nitrosend 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 5d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (graph/provider-operation/nitrosend-operation.mjs, graph/provider-operation/nitrosend-operation.test.mjs, review-content.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 216 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Nitrosend

Use this as the single public Runx surface for Nitrosend customer operations. Local account runners bind the API key only to the local runtime. The hosted review-content runner calls one bounded provider.read operation whose Cloud adapter retains credential custody. No runner accepts an API key as skill input or returns one in a receipt.

This skill is not for Nitrosend customer-support administration or team Slack work. Those are product-operator concerns owned by the Nitrosend repository.

Choose the runner

  • status (default): live account, brand, sender, domain, provider, warmup, and deliverability readiness.
  • billing-status: read the current account subscription and eligible paid-plan catalog together. It creates no checkout; prepaid balance and add-funds readiness remain a distinct funding block in the status evidence.
  • plan-checkout: re-read current billing and plans, approve one exact plan, create the idempotent hosted checkout or confirmed in-place plan change, then read billing again. A checkout URL is pending operator work, not proof of payment or activation.
  • plan-checkout-status: reconcile one returned plan-purchase ID without creating another checkout. Use it after hosted approval, timeout, or an ambiguous client response.
  • configure-sender: read, approve, update, and independently read back one explicitly selected brand's exact sender defaults. It configures no content, audience, campaign, flow, or delivery.
  • analytics: live account, campaign, flow, or message insights.
  • review-delivery: read-only content and preflight review. Flow review requires the exact immutable revision_id; campaigns and templates do not.
  • review-content: read-only spam and accessibility review for bounded inline email content. It accepts no account entity, audience, delivery, or mutation input and is safe to compose behind a payment-as-access vendor endpoint.
  • plan-campaign, plan-flow, plan-transactional, and plan-import: bounded agent judgment that produces a reviewable request without provider completion.
  • compose-email: read the live Nitrosend authoring contract, let one bounded agent author its exact next call, and return authoritative MCP validation. It never persists a draft or gains delivery authority.
  • apply-draft: apply exact reviewed arguments for a campaign, flow, template, segment, or remote image ingest. Image ingest validates the remote bytes and returns a durable Nitro-hosted brand-library URL. It never sends or activates.
  • approve-delivery: approve a reviewed campaign or an exact flow revision without delivering.
  • send-campaign: send or schedule an already-approved campaign after a fresh provider review and explicit approval.
  • activate-flow: publish an exact already-approved flow revision after a fresh review and explicit approval.
  • send-transactional: dry-run or send one idempotent message to one recipient.
  • import-contacts: dry-run or import at most 100 inline consented records.
  • import-contacts-csv: validate or upload a local CSV through Nitrosend's authorized direct-upload path. File bytes and signed URLs never enter the agent packet or receipt.
  • import-status: make one bounded status read for an asynchronous import.
  • segment-from-prose: internal planning lane for the current supported filter catalog; unsupported filters are rejected rather than approximated.

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.
