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 | $0.00040 | $0.02988 |
| Opus 5.5 | $0.00016 | $0.01195 |
| Sonnet 5.5 | $0.00008 | $0.00598 |
| Haiku 4.5 | $0.00004 | $0.00299 |
Grade A, and why
tax-compliance-management 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 — 253 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tax Compliance Management
Manage all tax obligations — from the compliance calendar to filing deadlines to payment processing. Federal, state, local, payroll, sales tax, and income tax. Goal: nothing is ever filed late, underpaid, or missed.
Purpose
Tax compliance is non-negotiable — missed deadlines mean penalties, interest, and in extreme cases, personal liability for payroll taxes. Yet most startup finance teams manage taxes reactively, scrambling when deadlines approach. This skill provides a proactive, calendar-driven approach to tax compliance: tracking every filing obligation, managing the R&D credit (the single most valuable tax incentive for startups), and ensuring multi-state nexus is properly managed as the company grows.
When to Use
- "What taxes do we need to file?"
- "When is our next tax deadline?"
- "File payroll taxes / sales tax / income tax"
- "Calculate our estimated tax payment"
- "Are we compliant in all states we operate in?"
- "Track our R&D tax credit eligibility"
Inputs Required
- Current state tax obligations and filing history
- Payroll register and tax filings (941, 940, state)
- Revenue data by state (for sales tax nexus)
- R&D activity documentation (projects, engineers, time tracking)
- Vendor W-9/W-8BEN forms
- Prior year tax returns
- State registration status for all nexus states
Quick Reference
| Filing Frequency | Key Obligations | Due Date |
|---|---|---|
| Monthly | Payroll tax deposits, state payroll tax, sales tax | 15th-30th of following month |
| Quarterly | Form 941, FUTA deposit, estimated income tax | Last day of month following quarter |
| Annual | W-2/W-3 (Jan 31), 1099-NEC (Jan 31), Form 940 (Jan 31), Corporate income tax (Mar 15 or Apr 15) | Varies |
| Tax Type | Startup Relevance | Risk Level |
|---|---|---|
| Payroll tax | Every company with employees | CRITICAL — personal liability |
| Sales tax | SaaS/software companies | HIGH — unregistered nexus = back taxes |
| Income tax (federal) | C-corps pay 21% | MEDIUM — estimated payments |
| R&D credit | Any company building software | OPPORTUNITY — up to $500k/yr payroll tax offset |
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.
