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 | $0.00000 | $0.01133 |
| Opus 5 | $0.00000 | $0.00566 |
| Sonnet 5 | $0.00000 | $0.00227 |
| Haiku 4.5 | $0.00000 | $0.00113 |
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 7d 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tax Prep — Tax Prepper
"Prep your taxes."
This skill is the organizer, not the adviser: it collects, categorizes, and flags, so the accountant's expensive hours go to judgment instead of shoebox archaeology.
When to use
- "Tax season is coming and my records are a mess."
- "What does my accountant actually need from me?"
- "Am I missing deductions?" — the sweep hunts categories with suspicious zeros.
- "Set up my quarterly estimate reminders."
- Any time an expense ledger or bank export needs to become an accountant-ready pack.
Workflow
- Frame the job. Organizer, not adviser: nothing here decides what is deductible — it surfaces candidates and questions for a professional to rule on.
- Build the document checklist across five categories — income, expenses, assets, payroll, prior filings — and mark each item have / missing / n-a from what the user provides.
- Sweep the expense ledger with code. From pasted data or CSV, categorize every transaction into generic buckets: software and subscriptions, professional fees, insurance, rent and utilities, vehicle and mileage, equipment (depreciation candidates), travel and meals, training, bank and payment fees, bad debt, home office. Flag uncategorized and personal-looking rows instead of guessing.
- Hunt the zeros. Compare the buckets against how the business plainly operates: client-site visits all year but no mileage logged, a home-based business with no home-office entries, laptops bought but nothing tagged as equipment. Each suspicious zero becomes a flagged candidate — never a claim.
- Lay out the quarterly-estimate calendar. A four-slot template with the user's local due dates left to fill in, plus a monthly set-aside habit: a fixed percentage of net moved to a tax sub-account.
- Assemble the accountant handoff pack. File manifest with paths, summary totals (revenue, expenses by bucket, payroll, estimates already paid), the checklist, and the sweep.
- Write the open-questions list. Everything ambiguous, one line each, phrased as questions the accountant can answer in a single pass.
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.

tax-prep is a skill published in the GitHub repository alebgl77/claude-inc (14 stars, last pushed 4d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,133 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
