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 | $0.00197 | $0.05629 |
| Opus 5 | $0.00098 | $0.02815 |
| Sonnet 5 | $0.00039 | $0.01126 |
| Haiku 4.5 | $0.00020 | $0.00563 |
Grade A, and why
tax-provision-advisor 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.

Tax Provision Advisor — Reference Skill
Purpose
Provide the complete multi-jurisdiction framework for corporate income tax provision advisory — from the recognition and measurement of current and deferred taxes through valuation allowances, uncertain tax positions, Pillar Two interactions, and ETR reconciliation.
Part 1: ASC 740 vs. IAS 12 — Core Framework Comparison
Scope and Recognition
| Area | US GAAP (ASC 740) | IFRS (IAS 12) |
|---|---|---|
| Standard scope | All income taxes imposed by domestic or foreign jurisdictions | All income taxes (domestic and foreign), including withholding taxes on distributions to the reporting entity |
| Asset recognition threshold | All deferred tax assets recognized; reduce by valuation allowance if more likely than not (>50%) that some or all will not be realized (ASC 740-10-30-5) | Recognize deferred tax asset only to the extent it is probable (generally interpreted as >50%; aligned in practice) that sufficient future taxable profit will be available (IAS 12.24) |
| Deferred tax liability recognition | Recognize for all taxable temporary differences except the initial recognition exception (IAS 12 equivalent) and inside basis difference in investments under APB 23 / ASC 740-30 | Recognize for all taxable temporary differences except: (a) initial recognition of goodwill; (b) initial recognition exception (assets/liabilities where neither taxable profit nor accounting profit affected) |
| Rate used | Enacted rate at balance sheet date (ASC 740-10-25-47) — rate signed into law | Substantively enacted rate (IAS 12.47) — rate virtually certain to be enacted (e.g., passed by parliament awaiting royal assent) |
| Measurement | Tax basis × enacted rate; no discounting permitted | Tax basis × substantively enacted rate; no discounting permitted |
Key divergence — Rate: Under US GAAP, a tax rate change affects deferred taxes only when the legislation is signed into law. Under IFRS, the rate change affects deferred taxes once substantively enacted — which can be earlier (e.g., a budget announcement in the UK Parliament). This frequently results in timing differences in the provision between GAAP and IFRS preparers facing the same legislative cycle.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
