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.

SkillSpector: 6 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00152 | $0.03255 |
| Opus 5 | $0.00076 | $0.01628 |
| Sonnet 5 | $0.00030 | $0.00651 |
| Haiku 4.5 | $0.00015 | $0.00326 |
Grade A, and why
Power BI Custom 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 9d 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 — 323 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Power BI Custom Visuals Skill
Build new Power BI custom visuals from natural language using the
powerbi-visuals-tools SDK. Iteration is agent-driven on TypeScript
compile errors; visual correctness is checked once at the end with the
user.
This skill produces a .pbiviz package and embeds it into a PBIR report
via pbi visual import-custom. The TypeScript project lives next to
the .pbip folder, never inside it.
Prerequisites
The skill needs Node.js on PATH and the powerbi-visuals-tools npm
package. Both are installed on first run with the user's consent; never
silently.
Pinned versions (override via env vars if needed):
powerbi-visuals-tools@^5.6.0(env:PBIVIZ_VERSION)powerbi-visuals-api@^5.11.0(pinned in scaffoldedpackage.json)
The skill's edit patterns and AGENTS.md crib were written against these versions. Bump deliberately.
First-run prerequisite check
# 1. Probe Node
node --version || true
If node is missing, ask the user:
Node.js isn't installed. Custom visual development needs it. Install now? (yes/no)
- Windows:
winget install OpenJS.NodeJS.LTS- macOS:
brew install node- Linux: use your package manager or nvm
If user says yes, run the install command appropriate for their OS and re-probe. If user says no, stop the skill with a clear message.
pbiviz itself runs through npx --yes powerbi-visuals-tools@^5.6.0,
so there's no global install of the CLI itself. The first npx
invocation will fetch and cache it locally.
Discovery: existing project vs fresh scaffold
The skill's first action is always discover, not scaffold.
- Locate the user's PBIR project (the
.pbipfolder or its.Reportsibling). - Look for sibling directories matching
*-visual/containing apbiviz.json. - Branch:
- None found → fresh scaffold flow (see "Plan-then-code" below).
- One found → load it; jump to edit-validate-package-import loop.
- Multiple found → ask the user which one; do not guess.
What ships with it
1 file 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.

Power BI Custom Visuals is a skill published in the GitHub repository MinaSaad1/pbi-cli (452 stars, last pushed yesterday), licensed MIT. It adds 152 tokens to every session and 3,255 once invoked, about $0.0008 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 2026-08-30.
