What is calle-invoice-recovery?

A reference workflow for calling a client about an unpaid invoice through CALL-E. It supports a reviewed conversation and records outcomes such as payment, a promised date, escalation, or no response; the bundled preview cannot place live calls.

Use it to prepare and review overdue-invoice calls for freelancers or small agencies, then pass the outcome to a human or host system.

It provides a controlled process for debt follow-up while requiring a person to approve the script and any proposed payment arrangement first.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00047	$0.05270
Opus 5.5	$0.00019	$0.02108
Sonnet 5.5	$0.00009	$0.01054

Security

Grade A, and why

calle-invoice-recovery 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/dry-run.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

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.

When To Use

Use this skill when a freelancer or small agency needs to follow up on an overdue invoice with an overseas client via a phone call placed through CALL-E. The client must be reachable in a CALL-E-supported region (US, SG, MY, IN, AE, AU, CA, GB, VN, DE, JP, FR, MX, BR, ID, PH, KE, BD) and the conversation must be conducted in a CALL-E-supported language for that region (default: English; Bengali is not supported, so calls to Bangladesh are placed in English).

When Not To Use

The client requires a language CALL-E does not support (e.g. Bengali), or is in a region CALL-E does not support.
The operator has not explicitly authorized the call.
No invoice reference number and amount are available to anchor the conversation.
The debt is disputed or involves active legal proceedings — refer to a collections attorney.

Conversation Flow

The flow has five sequential phases. Every phase must complete before the call closes; every branch must terminate in one of the four defined outcomes (paid, committed_to_date, escalated, unresponsive). The agent never closes the call in an undefined state.

Changes

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.
