76%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The content is concise, specific, and well-structured with genuinely executable Flashbots code, but the core sandwich Solidity is outline-only and the destructive multi-step bundle workflow lacks explicit validation/simulation checkpoints. Adding a simulate-then-submit verification step and a runnable contract example would raise both weak dimensions.
Suggestions
Add an explicit validation checkpoint before submission, e.g. 'Simulate the signed bundle via fb.simulate() or eth_call to confirm profitability and inclusion order before sending,' with a fix/retry loop.
Replace the comment-only Solidity sandwich bundle with an executable contract snippet (or a concrete function signature + entry point) so the core mechanic is copy-paste ready, not just the JS relay glue.
Flesh out the mempool filter code (a concrete decode of swap calldata and the slippage-vs-gas-cost check) instead of leaving it as a comment hint.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and code-forward, assuming Claude's competence without explaining basic DEX/MEV concepts; nearly every line (sections on JIT, multi-block, defenses, pitfalls, OPSEC) earns its place. | 5 / 5 |
Actionability | Provides mostly executable guidance (web3 mempool streaming, a near copy-paste Flashbots bundle in JS), but the core sandwich construction is comment/outline-only Solidity and the Python mempool filter is an incomplete sketch, leaving minor gaps. | 4 / 5 |
Workflow Clarity | The detect-construct-submit sequence is present as headed sections, but this destructive/financial operation lacks explicit validation checkpoints (e.g. simulate bundle profitability, verify bundle inclusion) and a feedback loop, which caps workflow_clarity at 3 per the rubric. | 3 / 5 |
Progressive Disclosure | A single self-contained SKILL.md (~100 lines) with clearly headed, well-organized sections and one-level external references; good structure with no nesting, though the overview/recipe/ethics mix could be split for a cleaner overview. | 4 / 5 |
