portfolio-tracker

portfolio-tracker is a skill for Claude Code, Codex from keypo-us/keypo-cli. It costs 139 tokens per session (2,924 once invoked), scanned A, original, no licence file.

A tool for viewing all native and ERC-20 token balances held by an EVM wallet. ERC-20 tokens are a common standard for tokens on Ethereum-compatible blockchains, and EVM means the Ethereum-compatible execution system used by those networks.

In plain words
What is it for?
Use it to find the native balance and ERC-20 token holdings for an EVM address across supported mainnets and testnets.
Why use it?
It provides a complete wallet portfolio overview instead of checking the native coin and each token separately. It uses Alchemy's Portfolio API and supports both mainnet and testnet networks.

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

portfolio-tracker scanned grade A with 1 finding 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 7d 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.

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.
