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

bart-statutory-reference-checker 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.

BART: Statutory Reference Checker

When to Use

  • Auditing Singapore legal documents for statutory citation accuracy
  • Verifying that cited Singapore statutes exist and are properly referenced
  • Checking if statutory references have been amended or repealed
  • Academic work on Singapore legislation
  • Pre-filing review of submissions

How It Works

Backend (Python + Next.js frontend)

  1. Semantic search over Singapore statute text using Legal-BERT/GEMMA
  2. BM25 + reranker for precise citation matching
  3. ChromaDB vector store for fast retrieval
  4. Word Add-in integration for in-document checking

Word Add-in Features

  • Scan entire document for statutory references
  • Validate against live Singapore statute database
  • Flag missing amendments or repealed provisions
  • Suggest correct chapter/section references
  • Hover tooltips with current text of cited provisions

Output

Report showing:

  • All statutory references found
  • Validation status (valid, amended, repealed, not found)
  • Suggested corrections where needed

A verified or valid result means "the cited reference was found in the source statute database at the time of lookup" — not "this citation is authoritative" and not "this submission is fit to file." Every finding is a research aid that requires lawyer verification.

Audience and Work Shape

Audience: Singapore-qualified lawyers, paralegals, and academic users running a statutory cite-check on a Singapore-law document (typically a submission, opinion, or academic paper). Not for unsupervised drafting, non-lawyer use, or non-Singapore documents.

Work shape: Pattern-Matched Review. Claude (or the BART pipeline) surfaces candidate citation mismatches; the lawyer adjudicates. Output is a list of findings, not a sign-off.

Inputs and Halt-on-Missing

Required inputs before running:

  • The target document (path or selection) containing the citations to check.
  • The intended statute snapshot date (the version of the Singapore statute book the user wants citations checked against).
  • The scope of the check (whole document, named section, or selection).

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.
