What is twillm CLAUDE.md?

Repository instructions for twillm, a Node command-line tool that turns a Markdown vault into a live TiddlyWiki working directory. A Markdown vault is a folder of text notes, while TiddlyWiki is a wiki that runs in the browser.

Use them when changing the CLI, wiki template, test vault, Markdown rendering, file watching, link handling, or build and start behavior.

They explain which files are source templates, which folders are generated, and how to test changes without editing the wrong content.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01206	$0.01206
Opus 5.5	$0.00482	$0.00482
Sonnet 5.5	$0.00241	$0.00241

Security

Grade A, and why

twillm CLAUDE.md 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 2mo 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.

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Working on twillm

This is the twillm project repo, not an end-user vault. twillm is a Node CLI that materialises a TiddlyWiki working directory (twillm-wiki/) in a user's repo and serves their Markdown vault as a live-watched TiddlyWiki.

End-user docs are in README.md. Architecture notes, design decisions, and the TODO list are in DEVELOPMENT.md. Read both before non-trivial changes.

Repo layout

cli.js — CLI entry point. Detects the user's vault, materialises twillm-wiki/, spawns TiddlyWiki.
template-wiki/ — the wiki template that gets copied into a user's twillm-wiki/ on first run. Edit here to change what users get.
vault/ — test fixture. Sample Markdown content used by npm start and npm run build.
handoff.md, README.md, CLAUDE.md — docs.
twillm-wiki/ — generated at runtime by npm start / npm run build. Gitignored. Don't commit.

Editing the test vault

The tiddlers in vault/ are demo content. Add to them when you want to exercise something live (rendering, watcher behaviour, link resolution). Same conventions a user would follow:

Markdown with YAML frontmatter
One tiddler per file: vault/<Title>.md
Frontmatter title should match filename
tags as YAML arrays: tags: [concept, multi word tag]
Don't include type — .md implies text/x-markdown and it round-trips out
created/modified are optional; if present they round-trip as ISO-8601 strings
Wiki links: [[Target Title]] or [[Display|Target Title]]

Editing template-wiki/

This is what users get. Be conservative — new files ship to everyone who runs npx github:Jermolene/twillm. Changes to existing files only reach fresh materialisations: files already present in a user's twillm-wiki/ are never overwritten.

template-wiki/tiddlywiki.info — wiki configuration. Plugins listed here are required of every user.
template-wiki/tiddlers/$__SiteTitle.tid, $__SiteSubtitle.tid — defaults users will probably override
template-wiki/tiddlers/$__config_SyncPollingInterval.tid — controls how often the browser polls. 2 seconds today.
template-wiki/tiddlers/vault-loader/tiddlywiki.files — overwritten at runtime by cli.js with the user's absolute vault path. Don't rely on its contents.

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.
