reg-change-triage

reg-change-triage is a skill for Claude Code, Codex from microsoft/cat-agent-skills. It costs 169 tokens per session (2,263 once invoked), scanned A, original, MIT.

A brief about a new or changed regulation that explains what changed, when it matters, who may be affected, and which obligations and policies need review. It proposes applicability and actions for a human to decide; it does not decide compliance.

In plain words
What is it for?
Use it to identify primary-source obligations, build a timeline, find potentially affected parties and policies, record possible gaps, and track proposed actions.
Why use it?
It turns a long rule or update into a dated work list while avoiding unsupported claims about requirements, applicability, or compliance.

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

reg-change-triage 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 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/lint_deliverable.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 175 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Scope

Do: identify regulatory instruments, build date ladders, extract changed obligations, propose applicability, locate candidate affected policies, build action trackers Do not: state requirements from memory, treat proposed rules as obligations, decide applicability, materiality, or compliance, claim candidate policies provide coverage, register, file, or send anything

When NOT to Use

  • Clause-by-clause coverage of one policy against one rule — use policy-gap-analysis instead.
  • A published enforcement action or consent order — use enforcement-action-review instead.
  • A vendor SOC 2 or third-party controls review — use vendor-risk-review instead.
  • Formatting, charting, or restyling an existing workbook — use xlsx instead.

Regulatory Change Triage Brief

Turn one regulatory instrument into a brief a compliance owner can act on: what changed, by when, who it hits, and what the firm must look at.

You propose. A qualified human decides. Applicability, materiality, and required action are determinations — see house-rules.md § 2.


Read first

Read these in full before step 1. They are binding; this body only summarises them.

  • references/workflow.md — the full text of every step below, with the guardrails, source resolution, and footer detail.
  • references/house-rules.md — destination gate, determination gate, authority tiers, markers, footers, and § 12 data minimisation (every artifact, search, and chat reply, declines included).
  • references/reg-source-access.md — routing, the codification gap, precision filtering, the date ladder.
  • references/document-extraction.md — if the instrument was uploaded.
  • references/triage-outline.md — default brief and tracker structure: the output format.
  • references/self-check.md — the final self-check (step 10).

Workflow

1. Identify the instrument precisely

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.
