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 | $0.00053 | $0.01723 |
| Opus 5 | $0.00026 | $0.00861 |
| Sonnet 5 | $0.00011 | $0.00345 |
| Haiku 4.5 | $0.00005 | $0.00172 |
Grade A, and why
portal-page-design 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 12d 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 — 166 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Konnect Dev Portal page design
Goal
Turn a page intent into a well-structured Dev Portal page built from MDC (Markdown Components). Own the layout: which sections the page needs, which components express them, and how they compose into a consistent, responsive result. Never invent a component or prop from memory.
Clarify First
Ask two or three high-impact questions, each with a default to confirm:
- the page's primary goal and audience
- which sections are wanted (hero, feature columns, doc sections, API list)
- whether it should match an existing page's structure
Tool Selection
Prefer the Konnect MCP server: the authoritative, always-current source for MDC facts (syntax rules, available components, their props and slots, design tokens, usage examples, formatting, validation, page preview). When connected, take facts from it rather than memory, and read its MDC syntax guide once at the start of the session; the Workflow below then draws components, tokens, validation, and preview from the server in order.
If not connected, recommend connecting it, since verified components, tokens, validation, and preview make the result much better. Otherwise work from general MDC knowledge and the user's existing portal files (see MDC essentials), and say plainly you cannot verify components, props, or tokens against live metadata and the result is less reliable.
Read and write pages and snippets directly through the server. Read current state
before an update, which overwrites content. Do not write to a live portal unless
the user explicitly asks; otherwise author locally or in a repo, and preserve an
existing kongctl or Terraform toolchain when one is in use.
Preview and iterate
Previewing needs the target portal's origin, a valid token, and a browser tool; without them, ask the user to preview in the Portal Editor. Set the viewport before opening the single-use preview URL, wait for full hydration (network idle, no pending animations), then screenshot. Regenerate the URL only when the MDC changes, not per width.
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.

portal-page-design is a skill published in the GitHub repository Kong/ai-marketplace (5 stars, last pushed 22d ago), licensed MIT. It adds 53 tokens to every session and 1,723 once invoked, about $0.0003 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 2026-08-31.
