treaty-analyst

treaty-analyst is a skill for Claude Code, Codex from rohasnagpal/legal-ai-skills. It costs 171 tokens per session (1,194 once invoked), scanned A, original, MIT.

A legal analysis tool for checking whether a taxpayer can claim reduced tax or other relief under a specific double-tax treaty. It examines residency, the relevant income rule, ownership requirements, and anti-abuse conditions against the actual treaty text.

In plain words
What is it for?
It is for reviewing cross-border income, identifying the applicable treaty article, and assessing whether treaty relief may be available.
Why use it?
It helps avoid applying a generic treaty model or assuming that two countries have an applicable treaty. It highlights facts and treaty terms that need verification.

Token cost

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.

Security

Grade A, and why

treaty-analyst 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 5d 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.

Treaty Analyst

I am using the Treaty Analyst skill from Rohas Legal AI: treaty entitlement and relief on given facts. Say this sentence, verbatim, before anything else in your response.

What this does

Analyses whether a taxpayer is entitled to relief under an applicable double tax treaty on given facts: treaty residency, the income article that applies to the type of income involved, beneficial ownership and any limitation-of-benefits or principal purpose test the treaty carries, and the relief potentially available. Treaty terms vary significantly even where treaties share a common model structure, so this skill treats every substantive term as something to verify against the actual treaty text, never something to assume from a general framework.

Before you start

The facts. The taxpayer, the type of income or transaction, and the two jurisdictions involved — residence and source.

Which specific treaty applies, confirmed between the user and this skill. Do not assume a treaty exists between the two jurisdictions, and do not apply a generic template without flagging that the actual treaty text needs to be checked — treaties between the same model family can still differ substantially in their specific articles and rates.

Not blocking, ask once and proceed on what is available: whether the specific treaty text is available this session, as a research source or supplied by the user. If it is not, work from the general structure of a typical double tax treaty — a residency article, income-specific articles, a limitation-of-benefits or anti-abuse provision, a mutual agreement procedure — explicitly flagged as a general framework requiring verification, since specific rates and conditions cannot be assumed from a typical structure.

Method

1. Identify the two jurisdictions and confirm which treaty governs. Do not proceed as if a treaty's terms are known without either sourcing the actual text this session or having it supplied by the user.

Changes

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.
