sendsets-cli is a skill for Claude Code, Codex from hashgraph-online/awesome-codex-plugins. It costs 143 tokens per session (3,198 once invoked), scanned A, original, Apache-2.0.

A command-line skill for operating SendSets as a signed-in user. SendSets handles product connections, mailboxes, sender warmup, events, and outbound email campaigns through its public API.

In plain words
What is it for?
Use it to sign in, check account health, connect an app, add or test mailboxes, run warmup, send product events, and build, validate, test, or launch campaigns.
Why use it?
It gives a defined setup and operating path while keeping credentials inside the CLI rather than exposing them to the agent.

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

sendsets-cli 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 17d 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.

How it starts

The opening of the file, as written. The whole thing — 224 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Driving SendSets through the sendsets CLI

sendsets is the customer CLI: it signs in as a person, keeps its own credential, and speaks only the public REST API. Every command is bounded by the scopes the sign-in approved. Never open, print or copy the CLI's stored credential; sendsets auth status --json says everything an agent needs.

If the binary is not on PATH, install it without a toolchain or root:

Install it with brew install addisonhoff/tap/sendsets (macOS, Linux) or scoop bucket add sendsets https://github.com/AddisonHoff/homebrew-tap then scoop install sendsets (Windows). Without a package manager, download the archive for your platform and checksums.txt from https://github.com/AddisonHoff/sendsets-releases/releases/latest, check the archive against checksums.txt, and unpack the sendsets binary onto PATH. It is also inside the backend image on a self-hosted instance (docker compose -p sendsets exec backend sendsets ...).

It is not sendsetsctl. That one talks to Postgres and exists for recovery and accounts (the sendsets-ops skill). If both are available and the task is product work, use sendsets.

The setup order

From nothing to a launched campaign, every step is a command and every failure prints a fix: line:

sendsets login --hostname sendsetsapi.com   # or SENDSETS_TOKEN=ssk_... plus SENDSETS_HOST=sendsetsapi.com
sendsets whoami                     # workspace, credential, scopes, agent policy
sendsets doctor                     # what is set up, what is not, a fix per gap; exit 1 when not ready

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.
