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 | $0.00088 | $0.03410 |
| Opus 5 | $0.00044 | $0.01705 |
| Sonnet 5 | $0.00018 | $0.00682 |
| Haiku 4.5 | $0.00009 | $0.00341 |
Grade A, and why
powerbi-deneb-visuals 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 11d 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 — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Deneb Visuals in Power BI (PBIR)
Report modification requires tooling. Two paths exist:
pbirCLI (preferred) -- use thepbircommand and thepbir-cliskill. Install withuv tool install pbir-cliorpip install pbir-cli. Check availability withpbir --version.- Direct JSON modification -- if
pbiris not available, use thepbir-formatskill (pbip plugin) for PBIR JSON structure and patterns. Validate every change withjq empty <file.json>.If neither the
pbir-cliskill nor thepbir-formatskill is loaded, ask the user to install the appropriate plugin before proceeding with report modifications.
Deneb is a certified custom visual for Power BI that enables Vega and Vega-Lite declarative visualization specs directly inside reports. Author specs using this skill.
Provider Policy
Prefer Vega-Lite for new Deneb visuals unless specific Vega-only features are required (signals, event streams, custom projections, force/voronoi layouts). Vega-Lite is more concise, easier to maintain, and covers most chart types. For advanced Vega features, see references/vega-patterns.md and the Vega documentation.
Visual Identity
- visualType:
deneb7E15AEF80B9E4D4F8E12924291ECE89A - Bundled runtime: Vega 6.2.0 / Vega-Lite 6.4.1 (since Deneb 1.8; use
v6.jsonschema URLs) - Data role: Single
datasetrole (all fields go into one "Values" well) - Default row limit: 10,000 rows (override via
dataLimit.override) - Provider:
vegaLite(default) orvega(when Vega-specific features needed) - Render modes:
svg(default, sharp text) orcanvas(better for large datasets)
Custom Visual Registration (Required)
Register deneb7E15AEF80B9E4D4F8E12924291ECE89A in report.json publicCustomVisuals array manually. Without this, the visual shows "Can't display this visual."
For more information, use the pbir-format skill and check the report.md reference.
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-deneb-visuals is a skill published in the GitHub repository santoshkanthety/powerbi-agent (2 stars, last pushed 12d ago), licensed MIT. It adds 88 tokens to every session and 3,410 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 2026-08-31.
