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 | $0.00117 | $0.01953 |
| Opus 5.5 | $0.00047 | $0.00781 |
| Sonnet 5.5 | $0.00023 | $0.00391 |
| Haiku 4.5 | $0.00012 | $0.00195 |
Grade A, and why
powerbi-fabric-app-templates 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 16d 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 — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Rayfin templates for Fabric Apps
A Rayfin template is a repo (or a path in one) carrying rayfin-template.yml at its root,
which rayfin init and create-rayfin can scaffold from. Templates are where a delivery
team's conventions live: the auth flow, the data-access layer, the chart primitives, the
theme, the validation harness. Getting the template right once is worth more than reviewing
twenty hand-rolled apps.
Read powerbi-fabric-apps first for the CLI, the SDK and rule zero (never write Rayfin API
code from memory). This skill covers only template selection and authoring.
Always list before choosing
The bundled template set moves with the CLI version. Enumerate it rather than trusting any list — including this one:
npx rayfin init --list-templates
Which template
| Situation | Template | Why |
|---|---|---|
| Analytical app over a Power BI semantic model | dataapp |
Ships DAX-generation guidance, chart primitives with cross-highlighting, a formatted data grid, centralised theming, format-string reuse and a Playwright validation workflow. Currently the CLI is the only supported way to use it. |
| Anything else, or a build you want to own end to end | blankapp |
Auth and nothing else. No framework opinions to unpick. |
| A team standard exists | your own template | See Authoring below. |
| User explicitly asks for a gallery app | an awesome-rayfin entry |
Read it before scaffolding; see the caveat below. |
For a Power BI–adjacent app, default to dataapp:
npm create @microsoft/rayfin@latest -- "<app-name>" --template dataapp --workspace "<workspace-name>"
Everything the dataapp template provides is work an agent would otherwise redo — badly —
in every session: authentication, DAX quality, and visual coherence. Without it the usual
failures are broken or empty visuals, inconsistent chart behaviour, and far more model
queries than the app needs.
What dataapp gives you
- Visuals: bar (vertical, horizontal, grouped, stacked), line with optional markers, area, scatter, pie and donut, heatmap, bubble, waterfall, KPI cards, and layered composites such as bars with data labels or dual-axis lines — with cross-highlighting.
- Data grid: headers from semantic model metadata, per-column number and date formatting from format strings, sorting, overflow handling, light/dark themes, and cell renderers for data bars, boolean indicators, clickable URLs, image cells with a lightbox, and multi-field cells.
- Theming: shared styles in one place, so a palette or font change flows to cards, buttons, charts, grids and tooltips instead of drifting per component.
- Format strings: define once per result column; reused across axes, tooltips, labels, cards and grid cells.
- Browser validation: a Playwright workflow that opens the real app and checks rendering, clipping, readability, grid overflow, loading/empty/error states, cross-highlighting and the console — at desktop and mobile widths.
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.

powerbi-fabric-app-templates is a skill published in the GitHub repository santoshkanthety/powerbi-agent (3 stars, last pushed 17d ago), licensed MIT. It adds 117 tokens to every session and 1,953 once invoked, about $0.0005 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 2026-10-07.
