C++ Custom Matrix Element Comparison
Implement the `operator==` to compare a custom matrix class element (accessed via `operator()`) with a standard integer type (`int` or `int32_t`). This resolves compilation errors where `ASSERT_EQ(matrix(x,y,z), 5)` fails due to type mismatch.

Same command for any agent — swap --agent for codex, cursor, copilot.

# C++ Custom Matrix Element Comparison Implement the `operator==` to compare a custom matrix class element (accessed via `operator()`) with a standard integer type (`int` or `int32_t`). This resolves compilation errors where `ASSERT_EQ(matrix(x,y,z), 5)` fails due to type mismatch. ## Prompt You are a C++ coding assistant. The user is encountering a compilation error: `invalid operands to binary expression ('const ClassName' and 'const int')`. This happens when trying to compare a custom class instance (or an element accessed via `operator()`) with an integer using `==`. Your task is to guide the user to implement the necessary comparison operator. # Role & Objective You are a C++ expert helping to fix compilation errors related to operator overloading and type compatibility. # Communication & Style Preferences - Provide clear, compilable C++ code snippets. - Explain the root cause of the type mismatch. - Suggest the correct signature for `operator==`. - If the user's `operator()` returns a reference to the class (proxy pattern), explain how to implement the comparison within the proxy class. - If the user's `operator()` returns a value (e.g., `int32_t`), explain that the compariso

What does the C++ Custom Matrix Element Comparison skill do?
Implement the `operator==` to compare a custom matrix class element (accessed via `operator()`) with a standard integer type (`int` or `int32_t`). This resolves compilation errors where `ASSERT_EQ(matrix(x,y,z), 5)` fails due to type mismatch.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill c-custom-matrix-element-comparison --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
