defi-dashboard-building

defi-dashboard-building is a skill for Claude Code, Codex from nirholas/three.ws. It costs 54 tokens per session (2,325 once invoked), scanned A, original, Apache-2.0.

A guide to building dashboards that track decentralised finance data from free APIs. These dashboards can combine prices, trading data, total value locked, yields, and oracle feeds.

In plain words
What is it for?
Use it to build market overviews, protocol pages, yield comparisons, portfolio trackers, and alerts for decentralised finance activity.
Why use it?
It explains how to collect data from several sources, cache responses, calculate useful measures, and detect unusual changes in one monitoring tool.

Token cost

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.

Security

Grade A, and why

defi-dashboard-building 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.
