Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00000 | $0.04265 |
| Opus 5.5 | $0.00000 | $0.01706 |
| Sonnet 5.5 | $0.00000 | $0.00853 |
| Haiku 4.5 | $0.00000 | $0.00426 |
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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 250 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.

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.

skill is a skill published in the GitHub repository smorand/mcp-htmleditor (0 stars, last pushed 10d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 4,265 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
