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

skill 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.

mcp-htmleditor — Skill

Description

mcp-htmleditor est un éditeur WYSIWYG HTML piloté par LLM. Il combine:

  • Un serveur HTTP local (port 7842 par défaut, port libre auto-choisi dans 7840-7849 si occupé, voir « plusieurs présentations en parallèle » plus bas) servant GrapesJS dans le navigateur
  • Un serveur MCP exposant 6 outils pour que l'agent LLM contrôle le fichier HTML
  • Des templates de référence et bootstrap pour démarrer rapidement
  • Un export vers PPTX (python-pptx) et DOCX (pandoc)

L'agent modifie le fichier HTML sur disque; le navigateur se synchronise automatiquement via polling.


Choisir et créer depuis un template

Le template se choisit à la création du fichier, via mcp-htmleditor new <key>. Il n'y a pas d'option --template sur serve: on crée d'abord, on édite ensuite.

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.
