wiki-ref

@wiki:<title> context references for Hermes Agent. Mention a Wikipedia article in a message and Hermes attaches the article's lead section to that turn, the same way @file: attaches a file. Add #Section to attach one section of the article instead.

Who influenced @wiki:Alan_Turing the most?
Compare @wiki:"Washington, D.C." with @wiki:Canberra
What changed in @wiki:Berlin#1900–1945?

Typing @wiki: in the TUI or the Desktop composer suggests article titles as you type.

Install

hermes plugins install wiki-ref --enable

Requires Hermes 0.21 or newer. The plugin has no dependencies beyond Hermes itself and needs no API key.

What the model receives

@wiki:Alan_Turing adds a block like this under --- Attached Context --- (captured from a real run, lead paragraph shortened here):

📌 @wiki:Alan_Turing (697 tokens)
Wikipedia (en): Alan Turing — English computer scientist (1912–1954)
https://en.wikipedia.org/wiki/Alan_Turing

Alan Mathison Turing (23 June 1912 – 7 June 1954) was an English mathematician and logician
widely regarded as the father of theoretical computer science. …

@wiki:Berlin#1900–1945 attaches that section instead, with the headings above it (captured from a real run, section text shortened here):

📌 @wiki:Berlin#1900–1945? (840 tokens)
Wikipedia (en): Berlin — Capital and largest city of Germany
https://en.wikipedia.org/wiki/Berlin#1900%E2%80%931945
Section: History › 1900–1945

In the early 20th century, Berlin had become a fertile ground for the German Expressionist
movement. …

A section comes with its subsections, up to the next heading of the same or a higher level.

The block also notes when the title was resolved through a redirect or normalization, when the page is a disambiguation page, and when the text was cut to the length limit. The empty brackets and stray spaces that Wikipedia's plain-text extracts leave where a pronunciation was (for example (; 23 June 1912) are removed. A title that does not exist, a network failure or a timeout does not attach anything; the model gets a line under --- Context Warnings --- instead, for example @wiki:Zzqx: plugin expansion error: no en.wikipedia.org article titled 'Zzqx'.

Writing titles

• Spaces can be written as underscores: @wiki:Alan_Turing.
• Or quote the title: @wiki:"Alan Turing". Quote titles that end in punctuation, such as @wiki:"Washington, D.C."; Hermes drops a trailing ., ,, ;, ! or ? from an unquoted reference.
• Capitalization of the first letter and redirects are resolved by Wikipedia: @wiki:alan_turing finds Alan Turing.

Sections

• @wiki:Title#Section attaches the section with that heading; @wiki:Title# is the same as @wiki:Title.
• Headings match regardless of case, and underscores read as spaces: @wiki:Alan_Turing#early_life_and_education.
• A title with spaces and a section go in one quoted value: @wiki:"New York City#Early history". @wiki:"New York City"#History loses the section, because Hermes ends a quoted value at the closing quote.
• When no heading matches, nothing is attached and the warning names the closest heading and the article's sections, for example no section 'early life' in 'Alan Turing' on en.wikipedia.org; did you mean 'Early life and education'? Sections: Early life and education, Career and research, ….
• A section that holds only citations or other content Wikipedia leaves out of its plain-text extract (for example Notes or References) is reported instead of attached empty.

Autocomplete inserts titles in a form that reads back correctly, quoting them when needed. It suggests titles only: once a # is typed it stays quiet, so it cannot replace the section being typed.

Settings

Set in config.yaml under the plugin's entry, or in the Desktop app under Capabilities → Plugins → wiki-ref. Changes apply to the next reference; no restart needed.

plugins:
  entries:
    wiki-ref:
      settings:
        language: en          # Wikipedia edition code: en, de, fr, simple, zh-yue, ...
        max_chars: 6000       # longest lead section or section attached per reference (200-50000)
        timeout_seconds: 10   # how long one reference may wait for Wikipedia (1-30)

An unusable value (an unknown-looking language code, a number out of range) is reported as a context warning on the reference that hit it rather than silently replaced.

Security and footprint

• Network: HTTPS GET requests to https://<language>.wikipedia.org/w/api.php only. Redirects are followed only when they stay on the same HTTPS host. Responses larger than 2 MiB are refused. A #Section reference is still one request: it downloads the article's plain text and cuts the section locally.
• What leaves the machine: the referenced title (not the section name), the text typed after @wiki: while autocomplete is open, and a User-Agent of the form hermes-wiki-ref/<version> (+https://github.com/EloquentBrush0x/hermes-context-refs), as Wikimedia's API etiquette asks for. Nothing else from the conversation is sent.
• No credentials: no API key and no cookies. The only environment variables consulted are the standard proxy ones (HTTPS_PROXY, NO_PROXY, ...), which Python's HTTP client honours.
• No files written, no subprocesses, no background work: requests happen only while a message with @wiki: is being expanded or while autocomplete is open.
• Time bound: each reference waits at most timeout_seconds (autocomplete: 3 seconds); a slow or stalled answer turns into a context warning instead of holding the turn.
• Untrusted content: article text is attached as quoted reference material. It is still text written by other people, so treat it like any web page the agent reads.
• Registration: register() only registers the @wiki: reference provider.

Limitations

• One reference attaches the lead section or one section, not the whole article. Section names are not autocompleted yet.
• One language per profile (the language setting); a single reference cannot pick another edition yet.
• The classic hermes CLI prompt does not autocomplete plugin prefixes; typing @wiki:Title still works there. hermes chat -Q (quiet mode) does not expand @ references at all.
