statute-amendments-trace

statute-amendments-trace is a skill for Claude Code from uk-agents/uk-legal-plugins. It costs 96 tokens per session (1,237 once invoked), scanned A, original, Apache-2.0.

A UK legislation research workflow that checks an Act’s current amendments and proposed future changes.

In plain words
What is it for?
It checks an Act’s current text and coverage, then finds pending bills that would amend it and reports their parliamentary stage and sponsor.
Why use it?
UK Acts can change after they are passed, so it helps distinguish the law currently in force from bills that may change it later.

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

statute-amendments-trace 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 — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/statute-amendments-trace

  1. Locate the statute: legislation_search(query="<title>").
  2. Get TOC and jurisdictional extent: legislation_get_toc(type=..., year=..., number=...).
  3. Check in-force amendments via legislation_get_section for sections of interest.
  4. Search for pending bills: bills_search_bills(query="<short title>").
  5. Report current status, jurisdictional extent, and pending bills with stage and sponsor.

Purpose

Trace the current amendment status of a UK Act and surface any pending parliamentary bills that would further amend it. Statutes are living documents — citing an Act without checking its amendment status risks relying on repealed, suspended, or superseded text. This skill checks both the current enacted state (via legislation.gov.uk) and the parliamentary pipeline (via the Bills API).

Workflow

Source discipline: If a uk-legal MCP tool returns empty or errored (status: empty / not_found / upstream_validation / etc.), do NOT supplement from training data or web search. Report the empty result to the user with the tool's next_steps / detail field surfaced, and ask for clarifying information (different spelling of a name, a date range, the source URL) rather than fabricating a plausible-looking answer. Empty results are HONEST signal — not a failure mode to paper over.

Step 1 — Locate the statute

Call legislation_search(query="<title>"). If the user gave only a partial title, include the year if known to narrow results. If multiple statutes match, list them and ask the user to confirm which one before proceeding.

Step 2 — Get the TOC and extent

Call legislation_get_toc(type=..., year=..., number=...) using the identifiers returned in Step 1. This returns:

  • The structural table of contents for the Act
  • The extent field: which jurisdictions the Act applies to (England, Wales, Scotland, Northern Ireland — note that extent can vary section by section)
  • Any amended version flag indicating that in-force amendments have been applied to the legislation.gov.uk text

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.
