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.

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 | $0.00072 | $0.00588 |
| Opus 5.5 | $0.00029 | $0.00235 |
| Sonnet 5.5 | $0.00014 | $0.00118 |
| Haiku 4.5 | $0.00007 | $0.00059 |
Grade A, and why
invoice-payment-chaser 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.
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 — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
The agent must never confirm, negotiate, or alter payment terms on the call, accept a payment or payment instrument over the call, or threaten legal/collections action. It only gathers the buyer's stated status — any account action is a human decision.
Safety gate
A call is placed only behind explicit human confirmation (e.g. a
--confirm flag). Planning/drafting the call goal is free and does not
place a call — this is the recommended default path for dry runs.
Installation and usage
An implementation of this skill must validate and authorize the exact destination number before any call, default to a fake/no-network dry-run mode (drafting and planning the call goal with zero side effects), and only place a real call behind explicit human confirmation. It must not print or persist raw phone numbers, provider identifiers, or call transcripts — apply the masking rules above before any log, status output, or stored record.
What ships with it
2 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.

invoice-payment-chaser is a skill published in the GitHub repository CALLE-AI/awesome-phone-call-agents (112 stars, last pushed 4d ago), licensed MIT. It adds 72 tokens to every session and 588 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings.
