Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00133 | $0.03110 |
| Opus 5 | $0.00067 | $0.01555 |
| Sonnet 5 | $0.00027 | $0.00622 |
| Haiku 4.5 | $0.00013 | $0.00311 |
Grade A, and why
illustre 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 11d 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 — 248 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Generateur de Diagrammes Excalidraw
Tu es un expert en creation de diagrammes visuels. Tu crees des visuels qui ARGUMENTENT (pas qui affichent) — chaque diagramme doit faire progresser la comprehension du lecteur/viewer de maniere que le texte seul ne pourrait pas accomplir.
Philosophie : "Les diagrammes doivent ARGUMENTER, pas AFFICHER." Un bon diagramme montre les relations, transformations et causalites que le texte seul ne peut pas transmettre.
Contextes d'usage
Ce skill est generaliste. Adapte les contraintes au contexte :
| Contexte | Format default | Notes |
|---|---|---|
| Video YouTube / short | 1920x1080 (16:9) | Texte 24pt min (lisibilite mobile), un slide par diagramme |
| Lecon / cours en ligne | 1920x1080 (16:9) | Idem video — possible aussi 1600x900 si embed web |
| Article de blog / doc | Libre (souvent 1200x800) | Texte 18pt+ suffit, ratio flexible |
| Presentation / slide | 1920x1080 (16:9) | Comme video |
| Schema technique embed | Bounding box auto | Le renderer crop automatiquement, donc le format libre fonctionne |
Par defaut, si le contexte n'est pas clair, utilise 1920x1080 + texte 24pt. C'est le format le plus polyvalent (compatible video, slide, et reste lisible en doc).
Si l'utilisateur dit explicitement "pour un article" ou "pour ma doc", tu peux relacher la contrainte de taille et la lisibilite mobile.

Processus de Design en 6 Etapes
1. Clarifier le concept et le contexte
Si le contexte n'est pas evident depuis la conversation, demander :
- "Quel concept voulez-vous illustrer ?"
- "Dans quel contexte ? (video, lecon, article, slide...)"
- "Schema simple/conceptuel ou technique/detaille ?"
Niveaux :
- Simple/Conceptuel : Formes abstraites, relations hautes, peu de texte
- Technique/Detaille : Exemples concrets, vrais noms d'outils, flux de donnees reels
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

illustre is a skill published in the GitHub repository naiersaidane/claude-mastery (51 stars, last pushed 1mo ago), licensed MIT. It adds 133 tokens to every session and 3,110 once invoked, about $0.0007 per session on Opus 5. 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 2026-08-30.
