rug-check

rug-check is a skill for Claude Code, Codex from Clawpump/agents-skills. It costs 40 tokens per session (1,228 once invoked), scanned A, original, MIT.

A read-only safety check for Solana tokens, which are digital assets on the Solana blockchain. It combines blockchain facts with RugCheck, a community risk-scoring service.

In plain words
What is it for?
Use it before buying, launching alongside, or investigating an unfamiliar token. It checks mint and freeze authority, liquidity, major holders, and risk warnings.
Why use it?
It shows whether token controls remain active, whether liquidity is locked or burned, and whether ownership is too concentrated before you trade.

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

rug-check 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 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/rugcheck.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

rug-check — Solana Token Safety

Read-only safety diligence for any Solana token mint. Never signs anything. It pairs with the ClawPump MCP trade/launch tools (swap_execute, launch_token_gasless, …) as the pre-flight that decides whether a token is safe to touch.

Two independent sources, cross-checked:

  1. On-chain (authoritative): Solana JSON-RPC for mint/freeze authority and real top-holder concentration — facts, not opinions.
  2. RugCheck (heuristic): a community risk score + flagged risks.

Helper: scripts/rugcheck.py. Endpoint reference: references/api-endpoints.md.

When to Use

  • Before any swap_execute into an unfamiliar token.
  • A user pastes a mint and asks "is this safe / is it a rug / can I ape this?"
  • Before launching or buying alongside an existing token.
  • Vetting a token a tracked wallet/whale just bought.

Quick Check (do this first)

python3 ~/.hermes/skills/crypto/rug-check/scripts/rugcheck.py check <MINT>

This prints a consolidated verdict: authority status, top-10 concentration, RugCheck score, and a CLEAN / CAUTION / RUGGABLE line with the reasons.

Key Concepts

  • Mint authority — if NOT revoked (non-null), the team can mint unlimited new supply and dilute you. Revoked (null) is the safe state.
  • Freeze authority — if NOT revoked, the team can freeze your tokens so you can't sell. Revoked (null) is safe.
  • LP locked vs burned — liquidity that's burned/locked can't be pulled (the classic "rug"). Unlocked LP is a red flag.
  • Top-holder concentration — a few wallets holding most of the supply can dump on everyone. >30% top-10 is elevated, >60% is dangerous. (Some large holders are locked LP / CEX / vesting — verify owners before concluding.)
  • RugCheck score — heuristic, not a guarantee. Use it as a signal, not a verdict.

Individual Commands

# RPC authority cross-check (mint can't be inflated / frozen?)
python3 scripts/rugcheck.py authority <MINT>

# Holder concentration from on-chain largest accounts
python3 scripts/rugcheck.py holders <MINT> --top 10

# RugCheck quick summary (+ risk flags) / full report
python3 scripts/rugcheck.py summary <MINT>
python3 scripts/rugcheck.py report  <MINT>

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

rug-check is a skill published in the GitHub repository Clawpump/agents-skills (2 stars, last pushed 2mo ago), licensed MIT. It adds 40 tokens to every session and 1,228 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
