Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00013 | $0.02309 |
| Opus 5 | $0.00006 | $0.01154 |
| Sonnet 5 | $0.00003 | $0.00462 |
| Haiku 4.5 | $0.00001 | $0.00231 |
Grade A, and why
history-research-guide 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 7d 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 — 261 lines — stays where its author put it; the contents beside it link to each section on GitHub.
History Research Guide
Overview
Historical research transforms raw evidence from the past -- documents, artifacts, images, oral testimonies -- into interpretive accounts that explain how and why things happened. The discipline demands a distinctive set of skills: source criticism, archival navigation, contextual reasoning, and the ability to construct arguments that are both evidence-based and theoretically informed.
The digital turn has expanded the historian's toolkit dramatically. Digitized archives, text mining, GIS mapping, and network analysis now complement traditional close reading. But the fundamentals remain unchanged: rigorous engagement with primary sources, awareness of historiographical debates, and transparent argumentation.
This guide covers the full research workflow for historians: finding and evaluating primary sources, navigating archives (physical and digital), applying source criticism, structuring historical arguments, and leveraging digital tools for analysis. It serves researchers at all levels, from graduate students designing their first archival project to established scholars integrating computational methods.
Source Criticism: The Foundation
External Criticism (Authenticity)
Questions to establish source authenticity:
1. PROVENANCE
- Where did this document come from?
- What is the chain of custody?
- Has it been reproduced, translated, or edited?
2. DATING
- When was it created? (Internal evidence: dates, references to events)
- Does the material form match the claimed period? (paper, ink, typeface)
- Are there anachronisms in language or content?
3. AUTHORSHIP
- Who created it? How do we know?
- Is the attribution reliable? (Handwriting analysis, stylistic evidence)
- Could it be pseudonymous or falsely attributed?
4. INTEGRITY
- Is the document complete or fragmentary?
- Has it been altered, censored, or interpolated?
- Are there multiple versions? Which is closest to the original?
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.

history-research-guide is a skill published in the GitHub repository wentorai/research-plugins (291 stars, last pushed 2mo ago), licensed MIT. It adds 13 tokens to every session and 2,309 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
