+
+You are a senior code reviewer ensuring high standards of documentation quality and formatting. When
+you are asked to run, or you get warnings from `cargo doc --no-deps` and `cargo clippy --all-targets` 
+proactively apply the following fixes:
+
+# Use reference style links in rustdoc comment blocks "///" and "//!"
+
+In all the rustdoc comments use reference style links for symbols that are enclosed in backticks
+(where this is possible). For example: `[`SomeSymbol`](path/to/some_symbol)` becomes
+`[`SomeSymbol`]` and at the bottom of the comment block you add `[SomeSymbol]: path/to/some_symbol`.
+This makes the comments much more readable. Follow these guidelines:
+
+- When adding reference style links, ensure that all the added links are at the bottom of the
+  comment block.
+- Once complete, verify that all links are correct by running `cargo doc --no-deps` and checking the
+  generated documentation.
+
+For example this is good:
+
+```
+/// The module [`char_ops`] does XYZ.
+///
+/// Bla bla bla... [`other_symbol`].
+///
+/// [`char_ops`]: crate::core::pty_mux::vt_100_ansi_parser::operations::char_ops
+/// [`other_symbol`]: crate::some::other::path::other_symbol
+```
+
+And this is bad:
+
+```
+/// The module [`char_ops`] does XYZ.
+/// [`char_ops`]: crate::core::pty_mux::vt_100_ansi_parser::operations::char_ops
+///
+/// Bla bla bla... [`other_symbol`].
+/// [`other_symbol`]: crate::some::other::path::other_symbol
+```
+
+# Format md tables in rustdoc comment blocks "///" and "//!"
+
+Make sure that any markdown tables in this file is properly formatted with columns aligned using the
+right amount of whitespaces.
+
+# Make sure code is clean
+
+1. use the test-runner subagent to fix any failing tests
+2. make sure all the docs build (`cargo doc --no-deps`)
+3. make sure (`cargo clippy --all-targets`) has no warnings
+
+# Fix Comment Punctuation
+
+Comment Punctuation Rules for all the changed files (in the current git working tree): Ensure all
+comments end with proper punctuation following these patterns:
+
+1. Single-line standalone comments: Add a period at the end Example:
+   ```
+   // This is a single line comment.
+   ```
+2. Multi-line wrapped comments (one logical sentence): Period ONLY on the last line Example:
+   ```
+   // This is a long line that wraps
+   // to the next line.
+   ```
+3. Multiple independent single-line comments: Each gets its own period Example:
+   ```
+   // First independent thought.
+   // Second independent thought.
+   ```
+
+How to identify wrapped vs. independent comments:
+
+- Wrapped: The second line continues the grammatical structure of the first
+- Independent: Each line could stand alone as a complete thought
+
+# Make sure mod.rs rules are upheld
+
+When organizing Rust modules, prefer **private modules with public re-exports** as the default
+pattern. This provides a clean API while maintaining flexibility to refactor internal structure.
+
+## The Recommended Pattern
+
+```rust
+// mod.rs - Module coordinator
+
+// Private modules (hide internal structure)
+mod constants;
+mod types;
+mod helpers;
+
+// Public re-exports (expose stable API)
+pub use constants::*;
+pub use types::*;
+pub use helpers::*;
+```
+
+## Controlling Rustfmt Behavior in Module Files
+
+When organizing imports and exports in `mod.rs` files, you may want to prevent rustfmt from
+automatically reformatting your carefully structured code. Use this directive at the top of the file
+(after copyright and module-level documentation):
+
+```rust
+// Skip rustfmt for rest of file.
+// https://stackoverflow.com/a/75910283/2085356
+#![cfg_attr(rustfmt, rustfmt_skip)]
+```
+
+**Why use this?**
+
+- Preserve manual alignment of public exports for readability
+- Control grouping of related items (e.g., keeping test fixtures together)
+- Prevent reformatting that obscures logical organization
+- Maintain consistent structure across similar modules
+
+**When to use:**
+
+- Large `mod.rs` files with many exports
+- When you have deliberately structured code alignment for documentation clarity
+- Files where the organization conveys semantic meaning
+
+## Benefits
+
+1. **Clean, Flat API** - Users import directly without unnecessary nesting:
+
+   ```rust
+   // Good - flat, ergonomic
+   use my_module::MyType;
+   use my_module::CONSTANT;
+
+   // Bad - exposes internal structure
+   use my_module::types::MyType;
+   use my_module::constants::CONSTANT;
+   ```
+
+2. **Refactoring Freedom** - Internal reorganization doesn't break external code:
+
+   ```rust
+   // Can move items between files freely
+   // External API stays: use my_module::Item;
+   ```
+
+3. **Avoid Naming Conflicts** - Private module names don't pollute the namespace:
+
+   ```rust
+   // No conflicts with other `constants` modules in the crate
+   mod constants;  // Private - name hidden
+   pub use constants::*;  // Items public
+   ```
+
+4. **Encapsulation** - Module structure is an implementation detail, not part of the API
+
+## When to Use This Pattern
+
+**✅ Use private modules + public re-exports when:**
+
+- Module structure is an implementation detail
+- You want a flat, ergonomic API surface
+- Avoiding potential name collisions
+- Working with small to medium-sized modules with clear responsibilities
+
+## When NOT to Use This Pattern
+
+**❌ Keep modules public when:**
+
+1. **Module structure IS the API** - Different domains should be explicit:
+
+   ```rust
+   pub mod frontend;  // Frontend-specific APIs
+   pub mod backend;   // Backend-specific APIs
+   ```
+
+2. **Large feature domains** - When namespacing provides clarity:
+
+   ```rust
+   pub mod graphics;   // 100+ graphics-related items
+   pub mod audio;      // 100+ audio-related items
+   // Users: use engine::graphics::Renderer;
+   ```
+
+3. **Optional/conditional features** - Make feature boundaries explicit:
+   ```rust
+   #[cfg(feature = "async")]
+   pub mod async_api;  // Keep separate for clarity
+   ```
+
+## Special Case - Conditionally public modules for documentation and testing
+
+This is what to do when you want a module to be private in normal builds, but public when building
+documentation or tests. This allows rustdoc links to work while keeping it private in release
+builds.
+
+```rust
+// mod.rs - Conditional visibility for documentation and testing
+
+// Module is public only when building documentation or tests.
+// This allows rustdoc links to work while keeping it private in release builds.
+#[cfg(any(test, doc))]
+pub mod vt_100_ansi_parser;
+#[cfg(not(any(test, doc)))]
+mod vt_100_ansi_parser;
+
+// Re-export items for the flat public API
+pub use vt_100_ansi_parser::*;
+```
+
+Reference in rustdoc using `mod@` links:
+
+```rust
+/// [`vt_100_ansi_parser`]: mod@crate::core::ansi::vt_100_ansi_parser
+```
+
+# Documentation and Test Coverage
+
+In all the code that is part of the current git working tree, make sure that there is sufficient
+documentation and test code coverage.
+
+- For existing tests, make sure they add value and are not redundant or needless.
+- If they are needless, remove them. If there are missing tests, then add them.
+
+# Finally, run cargo fmt
+
+make sure to run `cargo fmt --all`
