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

mailchimp 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (mailchimp.cjs), 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 — 302 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mailchimp

Use this skill for Mailchimp Marketing and Mailchimp Transactional work: audience/list inspection, subscriber lookup and controlled mutations, tags, merge fields, campaign draft operations, campaign content, scheduling/sending, campaign reports, automation and journey readouts, and Mandrill transactional message lookup or sends.

Default Workflow

  1. Start with credential-check when setup is uncertain. The helper emits gateway-resolved <env:...> and <secret:...> placeholders; it does not read runtime env or secret values itself. Missing MAILCHIMP_SERVER_PREFIX, MAILCHIMP_MARKETING_BASIC_AUTH, MAILCHIMP_MARKETING_OAUTH_TOKEN, or MANDRILL_API_KEY is surfaced by the gateway placeholder resolver or by a 401/403 upstream response. Do not run hybridclaw secret list, hybridclaw env list, grep, or local file inspection from the agent sandbox to decide whether Mailchimp values are configured; those checks can see the wrong runtime surface. For stored OAuth access tokens, use oauth metadata --auth oauth to retrieve the account-specific API endpoint and set MAILCHIMP_SERVER_PREFIX from the returned API endpoint host.
  2. Use mailchimp.cjs noun/verb commands for live work. Normal commands send the helper-built request through the HybridClaw gateway /api/http/request path, so the gateway resolves <env:...> and <secret:...> placeholders server-side. Use --request only for dry-run/debug output; do not normally reconstruct or relay httpRequest objects with the built-in http_request tool.
  3. Treat MAILCHIMP_MARKETING_BASIC_AUTH, MAILCHIMP_MARKETING_OAUTH_TOKEN, and MANDRILL_API_KEY as SecretRefs only. Never ask the operator to paste tokens into chat, never print raw Authorization headers, and never include Mandrill keys in --body-json.
  4. For audience writes, bulk subscriber plans, campaign draft/content writes, campaign schedule/send, and Mandrill sends, first run approval-plan, show the preview, and stop. After explicit operator approval for the named audience, campaign, or message target, run the approved helper command unchanged.
  5. For 401 or 403, stop after the first failure and ask the operator to verify the token, user role, Transactional provisioning, and data-center prefix. Do not retry with broader permissions.
  6. For 429, report rate-limit guidance from Retry-After or Mailchimp rate-limit headers when present. Do not start retry loops.
  7. Minimize subscriber PII in summaries. Prefer subscriber hashes for lookup and archive/tag operations. Include email addresses only when required to create or update a member.

mailchimp is a skill published in the GitHub repository HybridAIOne/hybridclaw (132 stars, last pushed yesterday), licensed MIT. It adds 34 tokens to every session and 3,373 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
