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.

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 | $0.00040 | $0.02288 |
| Opus 5.5 | $0.00016 | $0.00915 |
| Sonnet 5.5 | $0.00008 | $0.00458 |
| Haiku 4.5 | $0.00004 | $0.00229 |
Grade A, and why
html-portal-generator 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.

HTML Portal Generator
Convert any codebase into a single, self-contained HTML portal application. The output is one .html file with embedded styles, scripts, and data that works offline, on file:// protocol, and can be uploaded into AI application portals.
When to Use
- You have a codebase (CLI tool, library, API, framework) and need an interactive HTML representation of its functionality
- The HTML will be uploaded into a smart AI portal or application integration system
- You need all features to work standalone without a running server
- You want users to explore, validate, analyze, and interact with the product from a browser
Process
Follow these phases in order. Each phase builds on the previous.
Phase 1: Codebase Analysis
Understand what the product does before writing any HTML.
- Read project documentation: README, CLAUDE.md, architecture docs, changelogs
- Identify core crates/packages: Map each module's purpose and public API
- Catalog user-facing features: CLI commands, API endpoints, configuration options
- Extract data structures: Response types, configuration schemas, enum values
- Find existing UI code: Dashboards, templates, stylesheets (reuse their design language)
Produce a mental inventory:
- Feature list (what the product does)
- Data catalog (what entities/types exist)
- Command/API reference (how users interact)
- Visual identity (colors, fonts, layout patterns from existing UI)
Phase 2: Reference Analysis (if provided)
If the user provides a reference HTML app:
- Read the first and last ~3KB to understand structure (large files may be minified)
- Identify the design pattern: CSS variables, layout system, component structure
- Note the interaction model: controls bar, status bar, grid layout, tab navigation
- Extract the color palette and typography from CSS custom properties
Phase 3: Architecture Design
Design the portal as a single-page app with tab navigation.
Required structural elements:
- Sticky header with product name, version badge, and summary stats
- Tab navigation bar for switching between views
- Main container with
max-widthfor readability - Sticky status bar footer with links to docs/repo
- Toast notification system for user feedback
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.
- 1mo ago First seen · 248 lines · 40 tokens per session scan A 4dd086488683
html-portal-generator is a skill published in the GitHub repository athola/skrills (69 stars, last pushed 2d ago), licensed MIT. It adds 40 tokens to every session and 2,288 once invoked, about $0.0002 per session on Opus 5.5. 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.
