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 | $0.00050 | $0.01504 |
| Opus 5 | $0.00025 | $0.00752 |
| Sonnet 5 | $0.00010 | $0.00301 |
| Haiku 4.5 | $0.00005 | $0.00150 |
Grade A, and why
standby 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 13d 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 — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Standby
Use this skill when the user has one slot to fill and many people who could take it, and only one of them may end up saying yes — a care home short a nurse at 05:40, a restaurant a commis before dinner service, a depot a loader before the trailer leaves.
standby is a cascade skill. It does not add a CALL-E backend queue, a provider-side campaign, a daemon, or new MCP tools. It sequences the existing one-off CALL-E call workflow: one call at a time, in an order the user supplies, stopping the moment someone accepts.
The distinction that matters: a broadcast campaign asks twenty people a question. A cascade asks one person a question, and asks the next one only because the first said no. Getting four acceptances for one shift is a worse outcome than getting none, because now a human has to un-invite three people.
When To Use
Use this skill for:
- filling a single open shift, slot, or appointment from a list of candidates
- on-call escalation where the next person is rung only if the previous one does not answer
- any "ring round until someone says yes" task
- shift-swap requests, cover requests, and last-minute no-show replacement
When Not To Use
Do not use this skill to:
- broadcast the same message to many people — that is a campaign, not a cascade, and this skill will refuse to run calls in parallel
- decide, on the agent's own authority, what an unclear answer meant
- fill several slots at once from one roster; run one cascade per slot, or the stop condition is ambiguous
- call anyone who is not on the roster the user supplied
- guess phone numbers, country codes, timezones, languages, or regions
- call a number the user has not confirmed the owner consented to receive calls on
- negotiate pay, hours, or terms on the call; the goal states the shift and asks yes or no
- retry a person who has already declined
- keep dialling after the shift has started
Required Inputs
Ask for any of these that is missing. Do not infer one from locale, phone number, UTC offset, or earlier unrelated context.
What ships with it
5 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.

standby is a skill published in the GitHub repository CALLE-AI/awesome-phone-call-agents (88 stars, last pushed yesterday), licensed MIT. It adds 50 tokens to every session and 1,504 once invoked, about $0.0003 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.
