What is codeck CLAUDE.md?

Project instructions for creating presentations with codeck, an AI presentation tool that produces a single HTML file. It defines the files, roles, workflow, and durable project records used to build a deck.

Planning slide decks, writing slide content and speaker notes, designing styles, building the HTML presentation, and preparing exports or speeches.

It keeps presentation content, design, decisions, and the fixed presentation engine organised in the expected places.

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	$0.01085	$0.01085
Opus 5.5	$0.00434	$0.00434
Sonnet 5.5	$0.00217	$0.00217
Haiku 4.5	$0.00109	$0.00109

Security

Grade A, and why

codeck 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.

Origin

This is a copy

100% identical to codeck AGENTS.md — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

codeck — AI presentation skill

Architecture

codeck outputs a single HTML file, built by build-html.sh wrapping assemble.sh:

Author	File	Role
Human (fixed)	`engine.js` + `engine.css` + `build-html.sh`	Navigation, fragments, overview, speaker mode, progress bar, final HTML validation
AI (per deck)	`custom.css`	`:root` variables + layout primitives + per-page styles + mobile
AI (per deck)	`slides.html`	`<section class="slide" data-notes="...">` free HTML

Engine code is fixed. AI handles content and visuals only.

Deck room

/codeck opens ~/.codeck/projects/{slug}/
  ↓
MEMORY.md + channel/ + tasks/ + threads/ + roles/
  ↓
Decision Ask records live in threads/ before any runtime question
  ↓
@outline → deck.md
  ↓
@design → DESIGN.md + custom.css + slides.html → build-html.sh → single HTML
  ↓
@review → export (PDF/PPTX) / speech

Core idea: fixed role lanes own artifacts; dynamic people from diagnosis.md shape the judgment inside those lanes. The room is the durable scope; necessary asks are decision records first and UI questions second.

Room documents have rank:

Current truth: MEMORY.md, deck.md, DESIGN.md, custom.css, slides.html, latest assembled HTML, speech.md when present.
Work state: diagnosis.md, active tasks, open threads plus the Decision Ask ledger, roles/*.md, latest valid review.md.
Audit trail: channel/YYYY-MM-DD.md, legacy PROJECT.md, legacy design-notes.md, superseded reviews, and old previews. Audit never overrides current truth.

Three diagnostic signals

Domain — determines outline role
Expression challenge — determines design role
Audience starting point — determines review role (inverse: listener most likely to struggle)

Directory structure

Skills resolve their install location in this order: CODECK_SKILL_DIR / CODECK_DESIGN_DIR / CODECK_EXPORT_DIR env overrides → ${CLAUDE_PLUGIN_ROOT}/skills/* (Claude Code plugin install) → plugin cache globs (~/.claude/plugins/cache/*/codeck/*/skills/*, ~/.codex/plugins/cache/*/codeck/*/skills/*) → flat installs (~/.agents/skills/codeck*/, ~/.codex/skills/codeck*/, ~/.claude/skills/codeck*/). The first match wins, so the same SKILL.md works as a Claude Code plugin, a Codex plugin, or a flat skills.sh install. Sibling lane directories are derived by codeck/scripts/resolve-dirs.sh (siblings hold in every layout), sourced from each skill's unified Setup bootstrap block.

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.
