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.

Security

Grade A, and why

html-editor 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 3d 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.

Résumé express (en attendant la sortie complète)

mcp-htmleditor templates                            # ei | carbon | doc
mcp-htmleditor new ei ma-presentation.html --serve  # créer + ouvrir l'éditeur

mcp-htmleditor export pptx in.html out.pptx         # export PPTX
mcp-htmleditor export docx in.html out.docx         # export DOCX (pandoc)

Workflow LLM: update_start() → écrire le HTML → update_end() → commit git. Le navigateur se synchronise par polling. Source de vérité = HTML single-page.

Distinction avec la skill pptx: pptx produit/édite des fichiers .pptx natifs (OOXML, pptxgenjs). html-editor édite en HTML et exporte en bout de chaîne. Si le prompt parle de HTML, c'est cette skill; sinon c'est pptx.

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.
