evm-token-decimals

evm-token-decimals is a skill for Claude Code, Codex from arbisoft/ai-skillforge. It costs 44 tokens per session (940 once invoked), scanned A, original, no licence file.

A guide to handling token decimals on EVM blockchains, where the same displayed amount can represent different underlying values on different tokens or chains.

In plain words
What is it for?
Use it when building bots, dashboards, or DeFi tools that look up token decimals, cache chain-specific values, or normalize token amounts safely.
Why use it?
It prevents silent calculation errors caused by using the wrong precision, especially for bridged tokens and cross-chain tools.

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

evm-token-decimals 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.

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.
