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 | $0.00070 | $0.02101 |
| Opus 5 | $0.00035 | $0.01051 |
| Sonnet 5 | $0.00014 | $0.00420 |
| Haiku 4.5 | $0.00007 | $0.00210 |
Grade A, and why
python-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 2d 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.

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.

python-visuals is a skill published in the GitHub repository data-goblin/power-bi-agentic-development (884 stars, last pushed 24d ago), licensed GPL-3.0. It adds 70 tokens to every session and 2,101 once invoked, about $0.0003 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.

quality-gate
Use before finishing or opening a PR for a large / multi-file change to drizzle-cube, to ensure code quality does not regress. Runs fallow audit (complexity, duplication, dead code, circular deps scoped to the diff, reporting issues the change introduces) plus a madge circular-dependency snapshot. Report-only — it…
add-query-mode
Use when adding a new analysis/query mode to drizzle-cube (e.g., cohort, path analysis). Covers backend types, query builder, executor/compiler integration, frontend adapter, store slice, hooks, UI components, tests, and icon.
add-chart-type
Use when adding a new built-in chart type to drizzle-cube. Covers type definition, component, config, the unified chartRegistry entry, lazy loading, icons, and exports.
excel-pivot-wizard
Generates pivot tables and charts from raw data using natural language commands. Targets business analysts and data teams working in Excel. Use when asked to create a pivot table, summarize data by category, analyze sales by region, show revenue breakdowns, or build cross-tab analyses. Trigger with "create a pivot…
debug
Run /debug to find and fix a bug's root cause: a test failing for an unclear reason, /check verify finding a failure, or behavior being wrong. Runs a reproduce, localize, hypothesize, test, fix, verify loop, makes the minimal fix, and hands a regression test to /test. No features, no extra refactors.
malloy-html-data-apps
Build or modify an in-package HTML data app for a Malloy Publisher package (a public/ directory the package serves). Use when the user wants a hand-authored HTML dashboard or web page backed by a package's Malloy models, with no build step.
