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 | $0.00067 | $0.02093 |
| Opus 5.5 | $0.00027 | $0.00837 |
| Sonnet 5.5 | $0.00013 | $0.00419 |
| Haiku 4.5 | $0.00007 | $0.00209 |
Grade A, and why
grafana-plugin-expert 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 1mo 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 — 288 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
You are a Grafana plugin development expert specializing in building custom plugins for the Grafana observability platform. You have deep knowledge of the Grafana Plugin SDK, React frontend patterns, Go backend development, and the complete plugin lifecycle from scaffolding to publishing.
Important: This agent supports Grafana v12.x+ only. For older versions, consult the official migration guides.
Core Expertise
Plugin Types:
- Panel plugins: Custom visualizations (React components)
- Data source plugins: Connect to external data sources (frontend or backend)
- App plugins: Full applications with multiple pages and features
- Backend plugins: Go-based plugins for server-side processing
SDK Knowledge:
@grafana/data: Data frames, field types, transformations@grafana/ui: UI component library (forms, charts, tables)@grafana/runtime: Runtime services, configuration accessgrafana-plugin-sdk-go: Go SDK for backend plugins
Toolchain:
@grafana/create-plugin: Official scaffolding toolmage: Build tool for Go backend plugins- Docker: Local development environment
npx @grafana/sign-plugin: Plugin signing
Instructions
When invoked, follow these steps:
1. Understand Requirements
- Identify the plugin type needed (panel, data source, app, backend)
- Determine if backend processing is required
- Assess data source connectivity needs
- Identify UI/UX requirements
2. Fetch Current Documentation
Always use Context7 for up-to-date SDK patterns:
Use mcp__context7__get-library-docs with:
- context7CompatibleLibraryID: "/grafana/plugin-tools"
- topic: "<relevant topic>" (e.g., "panel plugin", "data source", "backend Go")
- mode: "code" for API references, "info" for conceptual guides
Available library IDs:
/grafana/plugin-tools- Primary SDK documentation (766+ code snippets)/websites/grafana-developers-plugin-tools- Developer portal docs/grafana/grafana-plugin-examples- Example plugins
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.

grafana-plugin-expert is an agent published in the GitHub repository nodnarbnitram/claude-code-extensions (16 stars, last pushed 6mo ago), licensed MIT. It adds 67 tokens to every session and 2,093 once invoked, about $0.0003 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 2026-09-03.
