What is colloquium CLAUDE.md?

Project instructions for Colloquium, a tool that turns Markdown into slides for research talks. Markdown is plain text with simple formatting symbols.

Creating research presentations, building and serving slide files, capturing slides as images, and running the test suite.

They explain the commands and architecture needed to build, preview, test, and modify the slide generator correctly.

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	$0.01169	$0.01169
Opus 5.5	$0.00468	$0.00468
Sonnet 5.5	$0.00234	$0.00234
Haiku 4.5	$0.00117	$0.00117

Security

Grade A, and why

colloquium 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 9d 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.

Colloquium — Agent Instructions

What This Is

Colloquium is an agent-native slide creation tool for research talks. Markdown-based, git-friendly, AI-drivable.

Commands

Use uv for all Python operations
uv pip install -e . to install in dev mode
uv run colloquium build examples/hello/hello.md to build slides
uv run colloquium serve examples/hello/hello.md for dev server (with live reload)
To preview built slides, open the .html file directly (open examples/hello/hello.html), NOT via the serve URL
uv run colloquium capture examples/hello/hello.md to capture slides as PNGs
uv run pytest to run tests

Architecture Patterns

CSS

Slides use display:none by default, display:flex on .active
CSS specificity: .slide--type.active not .slide--type (avoids display override bugs)
CSS custom properties (--colloquium-*) for all theme colors/fonts
Humans can override with custom CSS or per-slide style directives

Navigation (presentation.js)

Keyboard: arrows, Home/End, Space, PgUp/PgDn, F (fullscreen), Esc
Click zones: left 1/3 back, right 2/3 forward
Touch swipe support
Hash-based URL routing (#1, #2, ...)
Slide counter + progress bar
Slide picker groups slides into collapsible chapters (data-chapter on each <section>, window.colloquium.chapters); section-break slides and  start chapters
Chapter bar (chapter_bar: true | bars | {labels, slides, progress}, normalized by deck.normalize_chapter_bar; per-slide  and ; no-chapter-bar class), footer.section_break overrides, and ```toc blocks are rendered at build time in build.py (_plan_chapters, _build_chapter_bar_html, _replace_toc_blocks), not in JS, so they appear in PDF export and capture too

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.
