archive-research

archive-research is a skill for Claude Code from AI-Riksarkivet/ra-mcp. It costs 85 tokens per session (1,360 once invoked), scanned A, original, Apache-2.0.

A guide for researching historical documents in Swedish national archives, including finding records, reading documents, and presenting transcriptions or translations. It explains how to cite exact archival references and pages.

In plain words
What is it for?
Browsing archival records, transcribing historical documents, translating old Swedish, and reporting findings with precise citations.
Why use it?
It helps avoid made-up archival details, unsupported links, and overconfident readings of imperfect OCR or handwriting recognition. It also separates what a document says from later interpretation.

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

archive-research 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 11d 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.

Archive Research Guide

Research integrity, methodology, and workflows for historical research using the Riksarkivet MCP tools.

Research Integrity Rules

This is an academic research tool. Accuracy and proper sourcing are paramount.

  1. Never fabricate data. Never guess or hallucinate reference codes, page numbers, dates, names, or any archival data. Every claim must come directly from tool results.
  2. Always cite precisely. Cite the exact reference code and page number when presenting information from a document (e.g. "SE/RA/420422/01/A I a 1/288, page 66").
  3. Only use returned links. Only use links explicitly returned by the tools (bildvisaren, ALTO XML, NAD links, IIIF URLs). Never construct or guess URLs — not even by combining a base URL with a reference code.
  4. Distinguish source from interpretation. Clearly separate what the document says (quote or close paraphrase with quotation marks) from your own interpretation or translation.
  5. Flag uncertainty. If a transcription is unclear, incomplete, or ambiguous, say so explicitly. Do not silently fill in gaps with plausible-sounding text. Remember: all transcriptions are AI-generated (HTR/OCR) and contain recognition errors — misread characters, merged words, and garbled passages are common.
  6. Mark translations. When translating old Swedish, mark it as a translation and note when the meaning is uncertain.
  7. Admit gaps. If you cannot find information the user is looking for, say so. Do not construct an answer from partial or unrelated results.

Understanding the Research Goal

Before making your first search, ensure you understand what the user is researching. If their intent is vague or unclear, ask clarifying questions:

  • What time period are they interested in?
  • What type of documents are they looking for (court records, church records, military, estates)?
  • Are they researching a specific person, family, place, or event?
  • What do they already know that could help narrow the search?

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.
