Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 2 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 2 hosts that are neither well-known infrastructure nor declared in the skill's frontmatter: docs.flipsidecrypto.xyz, install.flipsidecrypto.xyz.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

About this skill

What it does

The Flipside skill provides access to on-chain data flips, allowing AI agents to instantly reverse transaction outcomes. This capability is designed for strategic arbitrage and advanced trading strategies that require analyzing reversed transaction histories. The skill utilizes the Flipside CLI (Command Line Interface) which must be installed separately before use. This allows an agent to leverage Flipside's data processing capabilities within its workflow.

When to use it

  • Analyzing potential arbitrage opportunities by simulating reversed transactions.
  • Backtesting advanced trading strategies that rely on understanding transaction reversals.
  • Investigating unusual blockchain activity involving altered or reverted transactions.
  • Researching the impact of specific events on a blockchain through reverse transaction analysis.

Key capabilities

  • Provides access to Flipside's on-chain data flips.
  • Enables reversal of transaction outcomes for analysis.
  • Utilizes the Flipside CLI (Command Line Interface).

Example prompts

  • "Reverse the last 10 transactions from this wallet address and analyze their impact."
  • "Simulate a reversed transaction for this specific block height and report any arbitrage opportunities."
  • “What were the original outcomes of these five recently reverted transactions?”

Tips & gotchas

  • The Flipside CLI must be installed separately before using this skill. Use flipside --version to check installation, and follow the provided instructions if it's not found.
  • This skill provides access to data flips; understanding blockchain technology and transaction reversals is required to effectively interpret the results.
  • The skill relies on the functionality of the Flipside CLI and its associated data sources.
