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 | $0.00010 | $0.00504 |
| Opus 5 | $0.00005 | $0.00252 |
| Sonnet 5 | $0.00002 | $0.00101 |
| Haiku 4.5 | $0.00001 | $0.00050 |
Grade A, and why
tax-prep scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tax Prep
Organize financial records and supporting documents for "$ARGUMENTS" to prepare for tax filing. Compile income, deductions, and credits with proper documentation.
Prerequisites
None — utility skill, run anytime. Works best after completing the four-phase cycle (record, categorize, reconcile, report).
Process
-
Determine tax obligations:
- Entity type (sole proprietorship, LLC, S-corp, C-corp, partnership)
- Tax year and filing deadlines
- Applicable tax forms (1040, 1120, 1065, etc.)
- State and local filing requirements
-
Compile income documentation:
- Revenue by source and category
- 1099s received and issued
- Interest and investment income
- Other income (rental, royalties, gains)
-
Organize deductible expenses:
- Operating expenses by category with totals
- Home office deduction calculation if applicable
- Vehicle and travel expenses with mileage logs
- Depreciation schedules for fixed assets
- Retirement plan contributions
- Health insurance premiums
-
Prepare supporting schedules:
- Asset register with purchase dates and cost basis
- Loan interest statements
- Charitable contribution receipts
- Prior year carryforwards (losses, credits)
-
Create filing checklist:
- List every document needed for filing
- Mark what is available vs. missing
- Note estimated tax payments already made
- Flag items needing professional review
-
Write the artifact to
.metapowers/bookkeeping/$ARGUMENTS/tax-prep.mdwith sections:- Entity & Filing Info — entity type, tax year, deadlines, forms
- Income Summary — all income sources with totals
- Deductions Summary — all deductible expenses with totals
- Supporting Schedules — depreciation, assets, carryforwards
- Filing Checklist — document readiness tracker
- Estimated Tax Position — projected tax liability or refund
Output
The tax preparation package written to .metapowers/bookkeeping/$ARGUMENTS/tax-prep.md. Present a summary highlighting:
- Total income and deductions
- Estimated tax position
- Missing documents or items needing attention
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.
