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.

What it costs to keep this loaded
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 | $0.00054 | $0.00782 |
| Opus 5 | $0.00027 | $0.00391 |
| Sonnet 5 | $0.00011 | $0.00156 |
| Haiku 4.5 | $0.00005 | $0.00078 |
Grade A, and why
cowork-tax-prep-organizer 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 12d 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.

Cowork Tax Prep Organizer
Do the part of tax season that actually eats the weekend: finding, identifying, and organizing the documents. Input: one or more folders (Downloads, a documents dump, last year's tax folder for reference). Output: an organized package a CPA can work from and a precise list of what is still missing. This skill organizes; it does not compute taxes or give tax advice.
Workflow
- Build the personal checklist. From last year's return or folder (if provided) and a few questions (W-2 employment? contract income? brokerage accounts? mortgage? dependents? business entity?), build the expected-documents list: W-2s, 1099-NEC/MISC/INT/DIV/B/R, 1098s, K-1s, property tax bills, charitable receipts, estimated-payment confirmations, prior-year return.
- Sweep. Walk the folders and identify every tax-relevant document by content, not just filename -- payers, form types, tax year. Match each to the checklist. Flag wrong-year documents (the 2024 1099 hiding in the 2025 pile) and duplicates (the same W-2 downloaded three times).
- Organize. On approval, copy -- never move -- into a clean structure:
tax-2025/income/,deductions/,investments/,business/,prior-year/, with names like1099-nec-acme-corp-2025.pdf. WriteINDEX.mdmapping checklist to files. - Chase list. Output what is expected but missing, with where it likely lives ("Interest income appeared last year from Chase -- no 1099-INT found; check the bank's tax documents page, typically posted by Jan 31"). Sort by what blocks filing vs. nice-to-have.
- Ask-your-CPA list. Flag items a preparer should look at -- not conclusions: home-office-looking expenses for the self-employed, a brokerage form showing wash-sale codes, K-1 arrived vs. expected, estimated payments that do not sum to the notes. Phrase each as a question for the professional.
Rules
- Never compute tax liability, deductions, or refunds. Identify, organize, and question -- the CPA concludes.
- Copy, never move. Source folders stay intact.
- Tax year discipline: every document is tagged with its year, and wrong-year files are quarantined in the report, not the package.
- "MISSING" means "not found in the provided folders" -- state what was searched.
- Treat everything as sensitive: no SSNs, account numbers, or dollar amounts in console output or digests; specifics live only in the package files.
- If both spouses' or multiple entities' documents are mixed, separate them explicitly and confirm the split before organizing.
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.
