sent-routing-strategist

sent-routing-strategist is a skill for Claude Code, Codex from sentdm/sent-plugin. It costs 91 tokens per session (1,540 once invoked), scanned A, original, MIT.

A guide for choosing how Sent, a messaging service, sends messages through SMS, WhatsApp, or RCS. It explains automatic routing, fixed channels, fallback, rerouting, and delivery failure states.

In plain words
What is it for?
Use it when configuring the channel field, choosing between automatic and fixed delivery, understanding rerouting, or diagnosing Sent delivery results.
Why use it?
It prevents accidental duplicate messages and charges caused by treating a channel list as a fallback order. It also clarifies why a message was failed, filtered, blocked, or left on automatic routing.

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

sent-routing-strategist 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 9d 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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sent Routing Strategist

Routing is where the most expensive Sent misconceptions live. Two facts govern almost every decision:

  1. The channel array is a broadcast list, not a preference order. ["whatsapp", "sms"] with two recipients creates four messages and four charges. There is no fallback field and no ordered-preference syntax.
  2. Automatic routing is the fallback mechanism. Omit channel, or send ["sent"], and the platform selects a route, then reroutes across up to three distinct channel-and-provider pairs when a route-level failure occurs.

Decide the channel value

Intent Correct value Reason
Reach the recipient however works best omit channel or ["sent"] Enables route selection and reroute
Guarantee one specific channel ["sms"], ["whatsapp"], or ["rcs"] Pinning restricts matching to that channel and never crosses channels
Deliberately deliver the same content on several channels ["whatsapp", "sms"] Broadcast; expect one message and one charge per pair
"Try RCS, fall back to SMS" omit channel or ["sent"] An ordered array would broadcast; automatic routing performs the fallback

Any value outside sent, sms, whatsapp, and rcs returns 400. When a user asks for ordered fallback, name the misconception explicitly before writing code, because the failure mode is duplicate delivery and duplicate cost rather than an error.

What a pinned channel gives up

Pinning restricts route matching to the named channel. Rules without a channel constraint still match and resolve to the pinned channel, so pinning does not require channel-specific rules to exist. A pinned send never crosses to a different channel, though same-channel provider hops remain possible when a rule permits them. If no route exists on the pinned channel, the message ends FAILED with no route matched — it does not silently fall back.

Pin when a compliance, contractual, or content constraint requires a specific channel. Otherwise prefer automatic routing.
