# Task Plan: Resolve Compilation and Ambiguity Issues in `macro_tools`
### Goal
* To resolve compilation errors and ambiguous name conflicts within the `macro_tools` crate, specifically related to module imports and `derive` attribute usage, and to properly expose necessary types for external consumption, enabling `derive_tools` to compile and test successfully.
### Ubiquitous Language (Vocabulary)
* `macro_tools`: The Rust crate being modified, providing utilities for procedural macros.
* `derive_tools`: A dependent Rust crate that uses `macro_tools` and is currently failing due to issues in `macro_tools`.
* `Glob Import`: A `use` statement that imports all public items from a module using `*` (e.g., `use crate::*;`).
* `Derive Ambiguity`: A compilation error (E0659) where the `derive` attribute macro conflicts with a glob-imported item also named `derive`.
* `GenericsWithWhere`: A specific type within `macro_tools` that needs to be publicly exposed.
### Progress

* N/A
### Relevant Context
* Control Files to Reference (if they exist):
* `./roadmap.md`
* `./spec.md`
* `./spec_addendum.md`
* Files to Include (for AI's reference, if `read_file` is planned):
* `module/core/macro_tools/src/lib.rs`
* `module/core/macro_tools/src/attr.rs`
* `module/core/macro_tools/src/attr_prop/singletone.rs`
* `module/core/macro_tools/src/generic_params.rs`
* `module/core/macro_tools/src/generic_params/mod.rs` (if exists)
* Crates for Documentation (for AI's reference, if `read_file` on docs is planned):
* `macro_tools`
* External Crates Requiring `task.md` Proposals (if any identified during planning):
* `module/core/derive_tools` (Reason: `derive_tools` tests failed during finalization, but direct modification is now out of scope.)
### Expected Behavior Rules / Specifications
* The `macro_tools` crate should compile without errors or warnings.
* `GenericsWithWhere` should be accessible from `macro_tools`'s own tests and examples.
### Crate Conformance Check Procedure
* **Step 1: Run Tests for `macro_tools`.** Execute `timeout 90 cargo test -p macro_tools --all-targets`. If this fails, fix all test errors before proceeding.
* **Step 2: Run Linter for `macro_tools` (Conditional).** Only if Step 1 passes, execute `timeout 90 cargo clippy -p macro_tools -- -D warnings`.
### Increments

##### Increment 4: Expose `GenericsWithWhere` publicly
* **Goal:** Make `GenericsWithWhere` accessible for external use, resolving `E0412: cannot find type GenericsWithWhere` errors in dependent crates/tests.
* **Specification Reference:** Problem Statement / Justification, point 19.
* **Steps:**
* Step 1: Read `module/core/macro_tools/src/generic_params.rs` and `module/core/macro_tools/src/generic_params/mod.rs` (if it exists).

* Step 3: Apply the necessary change to expose `GenericsWithWhere`.
* Step 4: Perform Increment Verification.
* Step 5: Perform Crate Conformance Check.

* Step 4: Analyze all outputs to confirm success.
* **Commit Message:** chore(macro_tools): Finalize fixes and verify macro_tools compatibility
### Task Requirements
* All compilation errors and warnings in `macro_tools` must be resolved.
* The `derive` ambiguity issue must be fixed without using `#[allow(ambiguous_glob_reexports)]`.
* `GenericsWithWhere` must be publicly accessible within `macro_tools`.
### Project Requirements
* Must use Rust 2021 edition.
* All new APIs must be async (N/A for this task, as it's a fix).
* Prefer `macro_tools` over `syn`, `quote`, `proc-macro2` as direct dependencies. (Already adhered to by `macro_tools` itself).
* All lints must be defined in `[workspace.lints]` and inherited by crates.
### Assumptions
* The `macro_tools` crate's internal tests (if any) are sufficient to cover its own functionality after fixes.
* The `#[cfg]` attribute error is a simple syntax error and not indicative of a deeper conditional compilation issue.
### Out of Scope
* Adding new features to `macro_tools` beyond what is required to fix the identified issues.
* Extensive refactoring of `macro_tools` beyond the necessary fixes.
* Addressing any issues in `derive_tools` or `derive_tools_meta`.
### External System Dependencies (Optional)
* N/A
### Notes & Insights
* The `derive` ambiguity is a common issue with glob imports and attribute macros. A systematic review of `use crate::*;` in `macro_tools` might be beneficial in the future, but for this task, only the problematic instances will be addressed.
