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 | $0.00037 | $0.00575 |
| Opus 5 | $0.00018 | $0.00287 |
| Sonnet 5 | $0.00007 | $0.00115 |
| Haiku 4.5 | $0.00004 | $0.00057 |
Grade A, and why
grafana-billing 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 4d 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 — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Grafana Billing Metrics Skill
Query key billing metrics from Prometheus and Loki through Grafana's data source proxy API.
Quick Start
# Query both staging and prod (default)
uv run .claude/skills/grafana-billing/scripts/billing_metrics.py
# Query specific environment
uv run .claude/skills/grafana-billing/scripts/billing_metrics.py --env staging
uv run .claude/skills/grafana-billing/scripts/billing_metrics.py --env prod
# JSON output for automation
uv run .claude/skills/grafana-billing/scripts/billing_metrics.py --json
# Filter to specific service
uv run .claude/skills/grafana-billing/scripts/billing_metrics.py --service prometheus
uv run .claude/skills/grafana-billing/scripts/billing_metrics.py --service loki
Environment Variables Required
GRAFANA_STAGING_API_KEY- API key for staging Grafana workspaceGRAFANA_PROD_API_KEY- API key for prod Grafana workspace
Key Metrics Captured
Prometheus
| Metric | Description |
|---|---|
| Active Time Series | Current count of active series (billing dimension) |
| Samples/sec | Ingestion rate (DPM = samples/sec * 60) |
| TSDB Storage | On-disk storage bytes |
| Top Cardinality | Top 10 metrics by series count |
Loki
| Metric | Description |
|---|---|
| Ingestion Rate | GB/day being ingested |
| Total Bytes | Cumulative bytes received |
| Active Streams | Number of active log streams |
| Memory Chunks | Chunks held in memory |
When to Use
Use this skill when the user asks about:
- Observability billing or costs
- Active time series counts
- Prometheus cardinality analysis
- Loki ingestion rates
- Storage usage for metrics or logs
- Comparing staging vs production usage
Instructions for Claude
- Run the billing metrics script to gather current data
- Present the results in a clear, formatted way
- Highlight any concerning metrics (high cardinality, rapid growth)
- Compare staging vs prod if both are queried
- Suggest cost optimization if metrics are unusually high
What ships with it
7 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.

grafana-billing is a skill published in the GitHub repository nodnarbnitram/claude-code-extensions (16 stars, last pushed 4mo ago), licensed MIT. It adds 37 tokens to every session and 575 once invoked, about $0.0002 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.
