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 | $0.00009 | $0.00427 |
| Opus 5 | $0.00005 | $0.00214 |
| Sonnet 5 | $0.00002 | $0.00085 |
| Haiku 4.5 | $0.00001 | $0.00043 |
Grade A, and why
payroll scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Payroll
Track employee wages, deductions, and payroll obligations for "$ARGUMENTS". Calculate gross and net pay, withholdings, and employer contributions.
Prerequisites
None — utility skill, run anytime.
Process
-
Gather employee information:
- List all employees and contractors
- Record: name, role, pay type (salary, hourly), rate, pay frequency
- Note tax filing status and allowances
- Identify any special deductions (benefits, garnishments, retirement)
-
Calculate gross pay:
- Salaried employees: annual salary / pay periods
- Hourly employees: hours worked x rate
- Include overtime, bonuses, commissions as applicable
- Track paid time off and sick leave balances
-
Calculate deductions:
- Employee withholdings: income tax, social security, medicare
- Employee contributions: health insurance, retirement (401k/pension), union dues
- Employer obligations: employer share of payroll taxes, insurance, workers' comp
- Other: garnishments, loan repayments
-
Determine net pay:
- Gross pay minus all employee deductions
- Verify against minimum wage requirements
- Calculate employer total cost per employee
-
Write the artifact to
.metapowers/bookkeeping/$ARGUMENTS/payroll.mdwith sections:- Payroll Summary — table with gross, deductions, and net per employee
- Withholdings Detail — breakdown of each deduction type
- Employer Costs — taxes and contributions paid by employer
- Totals — aggregate payroll cost for the period
- Upcoming Obligations — tax deposits and filing deadlines
Output
The payroll report written to .metapowers/bookkeeping/$ARGUMENTS/payroll.md. Present a summary highlighting:
- Total payroll cost (employee + employer)
- Net pay distributed
- Upcoming tax deposit deadlines
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.
