Chase an overdue cross-border invoice by phone when a written reminder has gone unanswered. Drafts a call goal scaled by the buyer's own learned payment history, places an authorized CALL-E call to the buyer, and returns a structured outcome (confirmed payment date or stated reason for delay) for human review before it is treated as resolved.
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
## When to use this skill Use when an invoice is significantly overdue relative to the buyer's own historical payment pattern, a written chaser has already been sent and gone unanswered, and a live phone call is warranted to get an explicit status. ## Intent specification The agent MUST have explicit intent for the run: the invoice (id, amount, currency, days overdue), the buyer's own learned payment pattern (typical lag, sample size) so tone is calibrated not generic, the authorized party to call, and the two acceptable resolutions — a confirmed payment date, or a specific stated reason for the delay. ## Phone number handling Numbers must be supplied in strict E.164 format (e.g. `+14155550123`). Output masking is required in logs/results unless the full number is strictly necessary for the call operation. Sample numbers in this skill's docs and fixtures use fictional reserved ranges only. ## Stopping mechanisms One call per invoice per chase cycle — no re-dialing the same invoice within a run. Ambiguous outcomes (no answer, refused, vague non-committal answers) are treated as unresolved and reported, not auto-escalated. ## High-stakes boundaries …

How to install
mdr add calle-ai/awesome-phone-call-agents/invoice-payment-chaser@sha256:d6c10c8f60a71b42The line at the top of this page pins the label git:20260911.97e39c8, 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.
