Names the domain (Aptos Move contracts, gas efficiency) and some actions (analyze, optimize, identify expensive operations, suggest optimizations), but the actions are somewhat generic and not highly concrete—e.g., it doesn't specify what kinds of optimizations or what 'expensive operations' means in practice.

Clearly answers both 'what' (analyze and optimize Aptos Move contracts for gas efficiency, identifying expensive operations and suggesting optimizations) and 'when' (explicit 'Triggers on:' clause with multiple trigger phrases).

Includes a strong set of natural trigger terms that users would actually say: 'optimize gas', 'reduce gas costs', 'gas analysis', 'make contract cheaper', 'gas efficiency', 'analyze gas usage', 'reduce transaction costs'. These cover multiple natural phrasings well.

Highly distinctive—targets a specific niche (Aptos Move contracts + gas optimization) with domain-specific trigger terms that are unlikely to conflict with general code review, Solidity gas optimization, or other blockchain skills.

The skill is extremely verbose at ~350+ lines. It repeats trigger phrases already in the YAML description, explains basic concepts Claude knows (what vectors are, what O(n) means), includes a full report template, and has extensive checklists that could be drastically condensed. Many patterns are shown with both BAD and GOOD examples when just the GOOD pattern with a brief note would suffice.

The code examples are concrete and mostly executable Move code, which is good. However, the gas profiling section uses a non-existent `gas::remaining_gas()` API, the simulation command is generic, and the skill is more of a reference catalog than actionable step-by-step guidance for analyzing a specific contract. It describes patterns rather than instructing Claude on how to systematically analyze and optimize a given contract.

There is no clear sequential workflow for performing a gas analysis. The skill is organized as a reference catalog of patterns and checklists but lacks a defined process: how to start analyzing a contract, what order to check things, when to validate, and how to iterate. The checklists at the end are helpful but disconnected from any workflow. No validation checkpoints or feedback loops exist for the optimization process.

The content is a monolithic wall of text with no bundle files to reference. It mentions `STORAGE_OPTIMIZATION.md` but no such file exists. All content—expensive operations, optimization patterns, measurement, checklists, report template—is inlined in a single massive file with no meaningful separation or navigation structure.
