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 | $0.00102 | $0.01404 |
| Opus 5 | $0.00051 | $0.00702 |
| Sonnet 5 | $0.00020 | $0.00281 |
| Haiku 4.5 | $0.00010 | $0.00140 |
Grade A, and why
reviewing-foreign-platform-and-us-income 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.
How it starts
The opening of the file, as written. The whole thing — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Reviewing Foreign Platform and US Income
Review foreign income, US-source income, and platform income facts for a Canadian IT contractor.
Core Rules
- Organize and flag foreign income facts, do not advise on treaty positions or residency.
- Do not determine final foreign tax credit entitlement.
- Do not determine final treaty treatment.
- Do not convert amounts using a rate you select; note the need for an annual average or transaction-date rate.
- Preserve uncertainty where income source, currency, or withholding facts are incomplete.
- Do not state that foreign income is or is not taxable in Canada.
- Do not state that a treaty exemption applies.
- Do not state that the user is ready to file.
- Use this phrase where relevant: "That is outside what this workflow covers. It is a question for a CPA before you file."
Inputs
Do not ask the user to share SIN, business number, account numbers, or client names. Use general descriptions and rounded amounts.
Accept any of:
- output from
identifying-income-sources - output from
organizing-t2125-gross-business-income - platform payment summaries (e.g. Upwork, Toptal, Stripe, PayPal)
- US 1099 forms or equivalent
- wire transfer or payment records
- user explanation in chat
Minimum useful input:
- at least one income item from a foreign source or foreign platform
- approximate amount and currency
Read from the shared input schema where available: case_id, tax_year, engagement_mode, user_profile, facts.business_activity, facts.foreign_income, documents.income_records, form_context, review_state.
Read from prior skill outputs where available: identifying-income-sources, organizing-t2125-gross-business-income.
Workflow
1. Confirm foreign income review is relevant
Check whether the user has income from sources outside Canada. If all income appears Canadian, return not_applicable.
2. Identify foreign income sources
For each foreign income item, identify:
- platform or payer name
- country of source
- currency
- approximate amount
- whether a 1099 or equivalent foreign tax document exists
- whether withholding was applied
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.
