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 | $0.00084 | $0.06875 |
| Opus 5 | $0.00042 | $0.03438 |
| Sonnet 5 | $0.00017 | $0.01375 |
| Haiku 4.5 | $0.00008 | $0.00688 |
Grade A, and why
visual-explainer 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 yesterday.
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 — 306 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Visual Explainer
Generate self-contained HTML files for technical diagrams, visualizations, and data tables. Never fall back to ASCII art when this skill is loaded.
Proactive table rendering. When you're about to present tabular data as an ASCII box-drawing table in the terminal (comparisons, audits, feature matrices, status reports, any structured rows/columns), generate an HTML page instead. The threshold: if the table has 4+ rows or 3+ columns, it belongs in the browser. Don't wait for the user to ask — render it as HTML automatically and tell them the file path. You can still include a brief text summary in the chat, but the table itself should be the HTML page.
Available Commands
| Command | What it does |
|---|---|
web-diagram |
Generate an HTML diagram for any topic |
visual-plan |
Generate a visual implementation plan for a feature |
slides |
Generate a magazine-quality slide deck |
diff-review |
Visual diff review with architecture comparison and code review |
plan-review |
Compare a plan against the codebase with risk assessment |
project-recap |
Mental model snapshot for context-switching back to a project |
fact-check |
Verify accuracy of a document against actual code |
Arguments
| Flag | Values | Effect |
|---|---|---|
--style <name> |
see the table below | Locks the aesthetic direction. Skips the "pick one and vary it" step in Workflow §1 — the choice is made, honor it exactly. |
--picker |
— | Selects a style instead of generating a page. Short-circuits everything below — see Style Picker. |
--theme <light|dark> |
— | Forces the page's initial mode. With no flag the page follows the OS. The toggle is always present regardless — this flag only sets the starting state. |
--slides |
— | Slide-deck output instead of a scrollable page. See Slide Deck Mode. |
--handbook |
— | Document output instead of a freeform visual page. See Handbook Mode. Mutually exclusive with --slides. |
--palette <hint> |
e.g. terracotta+sage, deep-blue+gold, or explicit hexes |
Overrides accent selection. Forbidden colors are still forbidden — if the hint contains one, use the nearest allowed hue and say so. |
--font <hint> |
e.g. crimson-pro+noto-sans-mono |
Overrides the font pairing. Forbidden --font-body values still rejected. |

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.

visual-explainer is a skill published in the GitHub repository NikiforovAll/claude-code-rules (141 stars, last pushed 2d ago), licensed Apache-2.0. It adds 84 tokens to every session and 6,875 once invoked, about $0.0004 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 2026-09-21.
