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 | $0.00119 | $0.01606 |
| Opus 5 | $0.00060 | $0.00803 |
| Sonnet 5 | $0.00024 | $0.00321 |
| Haiku 4.5 | $0.00012 | $0.00161 |
Grade A, and why
organizing-t2125-routine-operating-expenses 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 — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.
T2125 Routine Operating Expenses
Organize likely routine operating expenses for T2125 after the broader expense picture has already been identified.
Core Rules
- Work from identified expense categories, not from vague assumptions.
- Focus on likely routine operating expenses that may belong in ordinary T2125 expense areas.
- Separate routine operating costs from meals, travel, vehicle, home office, subcontractors, professional fees, and possible capital items where possible.
- Preserve uncertainty where support is incomplete or classification is mixed.
- Organize and flag, do not advise.
- Do not determine final deductibility.
- Do not determine final GST/HST treatment.
- Do not force mixed-use items into a fully business amount without support.
- Do not finalize capital vs current treatment where the facts remain unclear.
- Do not state that an expense is definitely allowable.
- Do not treat mixed-use internet or phone as fully business without support.
- 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-expense-categories - expense log or CSV
- bookkeeping export
- bank or card transaction summaries
- uploaded receipts
- user explanation in chat
- vendor/category spreadsheet
Minimum useful input:
- at least one identified expense item or expense category
- some indication of what the expense was for
- some support or explanation for the amount
Read from the shared input schema where available: case_id, tax_year, engagement_mode, user_profile, facts.business_activity, facts.home_office, facts.vehicle_use, documents.expense_support, transactions.expense_items, form_context, review_state.
Read from prior skill outputs where available: identifying-expense-categories.
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.
