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 | $0.00000 | $0.02516 |
| Opus 5.5 | $0.00000 | $0.01006 |
| Sonnet 5.5 | $0.00000 | $0.00503 |
| Haiku 4.5 | $0.00000 | $0.00252 |
Grade A, and why
security 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 266 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Wallet Risk Control — Security Skill
When to Use This Skill
Read and apply this skill whenever you are helping a user build a non-custodial crypto wallet or wallet-related application and the conversation touches any of the following:
- Mnemonic phrase or private key handling (generation, display, import, export)
- Transaction signing flows (
eth_sign,personal_sign,signTypedData) - Token approval or authorization flows (ERC-20
approve,Permit,Permit2) - DApp interaction (WalletConnect, injected provider, DApp browser)
- Transaction history or address display
- Risk-related UI components (warning banner, confirmation modal, risk badge)
- User safety questions ("how do I protect users from X", "should I warn the user about Y")
Do not apply this skill for general blockchain education unrelated to wallet UX or security implementation.
1. Core Threat Reference
The following attack categories are directly relevant to EVM web wallets built during this activity. Use these definitions to reason about whether a wallet feature introduces risk and what mitigations to suggest.
1.1 Malicious Contract Interaction & Blind Signing
Definition: Attackers induce users to sign cryptographically valid transactions or messages whose business logic (approve, Permit, Permit2) results in asset theft. Users cannot read raw calldata, creating an information asymmetry the attacker exploits.
Key risks for builders:
- ERC-20
approvewith unlimited allowance (uint256 max) presented without clear warning - Permit / Permit2 off-chain signatures that look identical to harmless "login" prompts
- Transaction calldata displayed as raw hex with no human-readable decode
Builder checklist:
- Always decode and display before the sign button is active: function name, contract address (with verification status), token, and exact approval amount
- Flag unlimited allowance with a Danger-level warning (see Section 2.2)
- Visually distinguish Permit / Permit2 signatures from login signatures in the UI
- Provide a user-editable amount field so users can reduce approvals to the exact amount needed
- Use Token Core CLI
analyzeto decode calldata before presenting to the user (see Section 4)
What ships with it

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.

security is a skill published in the GitHub repository consenlabs/token-ui (5 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,516 tokens. 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 2026-08-31.
