Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00056 | $0.03252 |
| Opus 5 | $0.00028 | $0.01626 |
| Sonnet 5 | $0.00011 | $0.00650 |
| Haiku 4.5 | $0.00006 | $0.00325 |
Grade A, and why
looker-studio 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.

Looker Studio (Google Data Studio)
Expert-level guidance for Looker Studio — building dashboards, connecting data sources, designing visualizations, and creating automated marketing reports.
Core Capabilities
Dashboard Design
- Layout and visual hierarchy best practices
- Executive summary vs detailed operational dashboards
- Mobile-responsive report design
- Interactive controls: date range selectors, filters, drill-downs
- Consistent styling with themes and color palettes
Data Sources & Connectors
- Native (free): Google Analytics 4, Google Ads, Google Sheets, BigQuery, Search Console, YouTube Analytics
- Partner connectors: Facebook Ads, Microsoft Ads, LinkedIn Ads, HubSpot, Salesforce, Shopify, Klaviyo, Semrush
- Community connectors: Hundreds of third-party sources
- Data blending: Join multiple sources on shared dimensions
- Custom queries: BigQuery SQL, Google Sheets formulas as data sources
Calculated Fields & Metrics
- Regex-based field creation (REGEXP_MATCH, REGEXP_REPLACE, REGEXP_EXTRACT)
- CASE statements for custom groupings and bucketing
- Date functions for period-over-period comparisons
- Aggregation (SUM, AVG, COUNT_DISTINCT, MEDIAN)
- Blended field calculations across sources
Formula Syntax Rules
- No comments allowed — Looker Studio formulas do not support
--,//, or/* */style comments. Never include comments in formulas. Add context in the field description instead. - No inline flags in simple cases — prefer
CONTAINS_TEXT(),LOWER(), or exact match over regex when possible - RE2 regex engine — supports
(?i)for case-insensitive, but does NOT support lookaheads/lookbehinds - String escaping — use
\\for literal backslash in regex patterns within string literals (e.g.,"\\s"for whitespace,"\\|"for literal pipe)
Report Automation
- Scheduled email delivery (PDF snapshots)
- Embedded reports in websites and portals
- Template reports for client scaling
- Data freshness monitoring
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.

looker-studio is a cursor rule published in the GitHub repository thatrebeccarae/claude-marketing (133 stars, last pushed 3mo ago), licensed MIT. It adds 56 tokens to every session and 3,252 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings.
