Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00098 | $0.01886 |
| Opus 5.5 | $0.00039 | $0.00754 |
| Sonnet 5.5 | $0.00020 | $0.00377 |
| Haiku 4.5 | $0.00010 | $0.00189 |
Grade A, and why
migrate-to-sent 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Migrate to Sent
Every migration from a major CPaaS provider hits the same five translation problems. Work them in this order, because the first one silently doubles cost and is invisible in tests.
1. Ordered fallback becomes automatic routing
Incumbent platforms express cross-channel delivery through different caller-side arrays, failover objects, messaging-service features, or application-level priority configuration. Do not assume those shapes have a direct Sent request-field equivalent.
Sent's channel array is a broadcast list. Porting an ordered array produces one message and one charge per recipient-channel pair, which passes tests and multiplies production spend. The correct translation is automatic routing — omit channel or send ["sent"] — which lets the platform select a route and reroute across up to three channel-and-provider pairs on the same message_id. Details belong to sent-routing-strategist; the migration rule is simply: never port an ordered channel list.
2. Status vocabularies do not line up
Incumbent statuses map onto Sent's, but Sent adds two states that have no equivalent and that break naive retry logic.
| Sent status | Closest incumbent analogue | Migration note |
|---|---|---|
QUEUED |
Twilio queued, Sinch QUEUED_ON_CHANNEL |
Accepted, not sent |
ROUTED |
no analogue | Route chosen; fires again on reroute |
SENT |
Twilio sent, Sinch MESSAGE_SUBMIT |
Provider handoff only |
DELIVERED |
delivered everywhere |
The first proof of handset receipt |
READ |
Twilio read, Sinch READ |
WhatsApp and RCS only |
FAILED |
failed, undelivered |
May still reroute; not necessarily final |
FILTERED |
Twilio error 21610 (opt-out) | Policy gate. Never retry |
BLOCKED |
account-level errors | Account precondition. Fix the account, then resend |
SCHEDULED |
no analogue | Quiet-hours parking; resumes automatically |
Two consequences for ported code. Handlers that treat every non-delivered terminal state as retryable will retry consent blocks, which is a compliance failure rather than a bug. And handlers keyed on numeric provider error codes — Twilio's 21610 is the classic — must be rewritten against Sent's string error.code families.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

migrate-to-sent is a skill published in the GitHub repository sentdm/sent-plugin (51 stars, last pushed yesterday), licensed MIT. It adds 98 tokens to every session and 1,886 once invoked, about $0.0004 per session on Opus 5.5. 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.
