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 | $0.00028 | $0.01950 |
| Opus 5 | $0.00014 | $0.00975 |
| Sonnet 5 | $0.00006 | $0.00390 |
| Haiku 4.5 | $0.00003 | $0.00195 |
Grade A, and why
payroll-processing 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 10d 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.

Payroll Processing
Purpose
Every employee and contractor must be paid correctly and on time, with all tax withholdings, benefits deductions, and compliance filings handled accurately. This skill calculates gross-to-net pay, applies federal/state/local tax tables, handles benefits deductions, and prepares the payroll register for review. Without it, payroll errors lead to compliance penalties, employee dissatisfaction, and cash flow surprises.
When to Use
- "Run payroll for this period"
- "Review payroll before processing"
- "Calculate net pay for these employees"
- "Process contractor payments"
- "File payroll taxes"
- "Update benefit deductions"
Inputs Required
- Employee roster — name, salary/hourly rate, pay frequency, tax withholding elections (W-4), benefit elections, state of employment.
- Pay period data — hours worked (hourly), PTO taken, commissions/bonuses earned, expense reimbursements.
- Prior payroll register — last period's numbers for sanity check.
- Tax rate tables — federal, state, local for each employee location.
- Benefits elections — health, dental, vision, 401(k) deferrals, HSA/FSA.
Quick Reference
| Calculation | Formula / Rule | Why It Matters |
|---|---|---|
| Gross Pay (Salaried) | Annual salary / Pay periods per year | Base for all deductions |
| Gross Pay (Hourly) | Hours worked × Rate (OT at 1.5× over 40 hrs) | Accurate for variable-hour employees |
| Federal Income Tax Withholding | IRS Pub 15-T tables based on W-4 and taxable wages | Largest single withholding; errors trigger penalties |
| FICA (Social Security + Medicare) | SS: 6.2% up to wage base / MC: 1.45% (0.9% additional over $200k) | Mandatory employer + employee portions |
| Benefits Deductions | Pre-tax: 401(k), medical, HSA / Post-tax: Roth 401(k), life insurance | Correct treatment prevents tax filing errors |
| Net Pay | Gross − Taxes − Deductions + Reimbursements | What employees actually receive |
| Total Employer Cost | Gross pay × 1.25–1.4× (incl. employer taxes, benefits, workers comp) | True cost of headcount for planning |
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.
