# Task: Fix `From` Derive Macro Issues in `derive_tools`

### Goal
*   To resolve compilation errors and mismatched types related to the `From` derive macro in `derive_tools`, specifically the `expected one of `!`, `.`, `::`, `;`, `?`, `{`, `}`, or an operator, found `,`` and `mismatched types` errors in `module/core/derive_tools/tests/inc/from/basic_test.rs`.

### Ubiquitous Language (Vocabulary)
*   `derive_tools`: The crate containing the `From` derive macro.
*   `derive_tools_meta`: The companion crate that implements the logic for the procedural macros used by `derive_tools`.
*   `From` derive macro: The specific derive macro causing issues.

### Progress
*   **Roadmap Milestone:** N/A
*   **Primary Editable Crate:** module/core/derive_tools
*   **Overall Progress:** 0/1 increments complete
*   **Increment Status:**
    *   ⚫ Increment 1: Fix `From` derive macro issues
    *   ⚫ Increment 2: Finalization

### Permissions & Boundaries
*   **Mode:** code
*   **Run workspace-wise commands:** true
*   **Add transient comments:** true
*   **Additional Editable Crates:**
    *   `module/core/derive_tools_meta` (Reason: Implements the derive macros)

### Relevant Context
*   Control Files to Reference (if they exist):
    *   `module/core/derive_tools/task_plan.md` (for overall context of `derive_tools` test suite restoration)
*   Files to Include (for AI's reference, if `read_file` is planned):
    *   `module/core/derive_tools/tests/inc/from/basic_test.rs`
    *   `module/core/derive_tools_meta/src/derive/from.rs`
*   Crates for Documentation (for AI's reference, if `read_file` on docs is planned):
    *   `derive_tools`
    *   `derive_tools_meta`
*   External Crates Requiring `task.md` Proposals (if any identified during planning):
    *   N/A

### Expected Behavior Rules / Specifications
*   The `From` derive macro should correctly generate code for `IsTransparentSimple` and other types, resolving the `expected one of ... found `,`` and `mismatched types` errors.
*   `derive_tools` should compile and pass all its tests after these fixes.

### Crate Conformance Check Procedure
*   **Step 1: Run Tests.** Execute `timeout 90 cargo test -p derive_tools --all-targets`. If this fails, fix all test errors before proceeding.
*   **Step 2: Run Linter (Conditional).** Only if Step 1 passes, execute `timeout 90 cargo clippy -p derive_tools -- -D warnings`.

### Increments
##### Increment 1: Fix `From` derive macro issues
*   **Goal:** Resolve the compilation errors and mismatched types related to the `From` derive macro in `derive_tools`.
*   **Specification Reference:** Problem Statement / Justification in `module/core/macro_tools/task.md` (original problem description) and the recent `cargo test -p derive_tools` output.
*   **Steps:**
    *   Step 1: Read `module/core/derive_tools/tests/inc/from/basic_test.rs` and `module/core/derive_tools_meta/src/derive/from.rs`.
    *   Step 2: Analyze the errors (`expected one of ... found `,`` and `mismatched types`) in `basic_test.rs` and the generated code from `derive_tools_meta/src/derive/from.rs`.
    *   Step 3: Modify `module/core/derive_tools_meta/src/derive/from.rs` to correct the code generation for the `From` derive macro, specifically addressing the syntax error and type mismatch for `IsTransparentSimple`.
    *   Step 4: Perform Increment Verification.
    *   Step 5: Perform Crate Conformance Check.
*   **Increment Verification:**
    *   Step 1: Execute `timeout 90 cargo test -p derive_tools --all-targets` via `execute_command`.
    *   Step 2: Analyze the output for compilation errors related to the `From` derive macro.
*   **Commit Message:** fix(derive_tools): Resolve From derive macro compilation and type mismatch errors

##### Increment 2: Finalization
*   **Goal:** Perform a final, holistic review and verification of the task, ensuring `derive_tools` compiles and tests successfully.
*   **Specification Reference:** Acceptance Criteria.
*   **Steps:**
    *   Step 1: Perform Crate Conformance Check for `derive_tools`.
    *   Step 2: Self-critique against all requirements and rules.
*   **Increment Verification:**
    *   Step 1: Execute `timeout 90 cargo test -p derive_tools --all-targets` via `execute_command`.
    *   Step 2: Execute `timeout 90 cargo clippy -p derive_tools -- -D warnings` via `execute_command`.
    *   Step 3: Analyze all outputs to confirm success.
*   **Commit Message:** chore(derive_tools): Finalize From derive macro fixes

### Task Requirements
*   The `From` derive macro must generate correct, compilable code.
*   `derive_tools` must compile and pass all its tests without warnings.

### Project Requirements
*   Must use Rust 2021 edition.
*   All new APIs must be async (if applicable).
*   Code must adhere to `design.md` and `codestyle.md` rules.
*   Dependencies must be centralized in `[workspace.dependencies]` in the root `Cargo.toml`.
*   Lints must be defined in `[workspace.lints]` and inherited by member crates.

### Assumptions
*   The `derive_tools_meta` crate is the sole source of the `From` derive macro's logic.
*   The `basic_test.rs` file accurately represents the problematic usage of the `From` derive.

### Out of Scope
*   Addressing other derive macros in `derive_tools`.
*   General refactoring of `derive_tools` or `derive_tools_meta` not directly related to the `From` derive issues.

### External System Dependencies (Optional)
*   N/A

### Notes & Insights
*   The `From` derive macro's generated code needs careful inspection to identify the exact syntax error.

### Changelog
*   [Initial Plan | 2025-07-05 11:48 UTC] Created new task to fix `From` derive macro issues in `derive_tools`.
