Defines a polite CALL-E invoice-recovery conversation, structured outcomes, and human-approval requirements for freelancers and small agencies; includes a no-call preview, while live dispatch and storage require a host integration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# CALL-E Invoice Recovery Skill A reusable phone-call skill that contacts a named client about an unpaid invoice via CALL-E, holds a multi-turn conversation to understand the client's situation, offers a payment arrangement when appropriate, and records the outcome (paid, committed-to-date, escalated, or unresponsive) for human review. Every action is draft-then-approve: the operator reviews the call script and any proposed arrangement before the call is placed or any commitment is logged. **This edition is a workflow reference and offline preview.** The only bundled executable is `scripts/dry-run.ts`, which cannot place calls. The live workflow and safety requirements below are instructions for an integrating host, not a shipped approval UI, transport, scheduler, or database. The host must provide and verify those controls before live use. See the [operator guide](../../docs/calle-invoice-recovery/README.md). ## When To Use …

How to install
mdr add calle-ai/awesome-phone-call-agents/calle-invoice-recovery@sha256:2d7845aa8d9a42fcThe line at the top of this page pins the label git:20260911.8235f5a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
