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 | $0.00057 | $0.00990 |
| Opus 5 | $0.00028 | $0.00495 |
| Sonnet 5 | $0.00011 | $0.00198 |
| Haiku 4.5 | $0.00006 | $0.00099 |
Grade A, and why
authentication-portal-themes 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Authentication Portal Themes
Create a deployable theme in the consuming application's theme directory, with the user's branding, working portal flows, and matching configuration. Start from the built-in templates for the AuthCrunch version the application runs. Use an existing custom theme as a design reference, then carry its styling onto those templates. Filesystem overrides do not inherit later upstream changes.
Choose the Customization Surface
- For colors, typography, spacing, and a logo, prefer UI parameters and custom CSS. Keep the built-in markup when it meets the request.
- For a branded page shell, favicon/metadata, or different layout, copy and override the affected templates. Unspecified aliases keep their built-in templates. A complete theme should account for every page the application exposes, including session continuation and logout confirmation when enabled.
- Keep application themes in the consuming application. Editing
pkg/authn/ui/page_templates/basicchanges the library's default UI and is appropriate only when that is the requested scope.
The React profile app under pkg/authn/ui/profile is a separate asset surface;
portal template overrides do not rebuild or restyle it automatically.
Build the Theme
- Inspect the application's AuthCrunch version, current UI configuration, portal mount, theme directory, brand assets, and exposed flows. Infer visual choices from supplied references; ask only for missing choices that affect the result. Do not assume a particular company, realm, hostname, or palette.
- Read configuration.md when selecting overrides,
wiring files, or debugging asset URLs. The registered theme remains
basic; a custom folder name is not a new value forui.theme. - Before changing markup, read template-contracts.md and inspect the corresponding current template, handler, and scripts. Keep authentication forms, conditional views, navigation, translations, and script hooks intact.
- Use brand-assets-and-color.md for suggested logo/banner/background sizes, formats, composition, and color palettes. Use design-and-validation.md for page layout, CSS ordering, and validation. Produce shared styles plus page-specific adjustments instead of forcing a narrow login card onto registration forms or identity/SSO tables.
- Deliver the templates/assets and the exact UI configuration needed to load them. Report which aliases changed, which use defaults, the required runtime paths, and which rendering/browser checks ran.
What ships with it
5 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.

authentication-portal-themes is a skill published in the GitHub repository greenpau/go-authcrunch (59 stars, last pushed yesterday), licensed Apache-2.0. It adds 57 tokens to every session and 990 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 2026-09-13.
