## Unreleased

- Read `BLOCK_TEMPLATE` and `ADDRESS` names from the `.def` files listed under `<DefinedEvents>` in PSC layers and refresh them when PSC or DEF files change
- Suggest block templates for `MOM_do_template` and addresses for `MOM_ask_address_value`, `MOM_force`, and `MOM_suppress`, each followed by variables
- Suggest `Always`, `Once`, and `Off` for the first argument of `MOM_force` and `MOM_suppress`
- Insert block templates, addresses, and modes in quotes without doubling typed or auto-closed quotes; insert variables with a leading `$`
- Add `BLOCK_LIST` and `ADDR_LIST` completion keywords that list all loaded block templates or addresses
- Format and lint `uplevel` bodies as Tcl scripts
- Format comments with a space after `#` (`#Comment` becomes `# Comment`); `##` separators, `#!`, and already spaced comments stay unchanged
- Stop the Python debug bootstrap with a clear error instead of hanging when no debugpy listener or only a stale one is available
- Reparse only the top-level TCL commands touched by an edit instead of the whole file
- Cache the workspace index in the extension storage so restarts skip reparsing unchanged files; the cache is discarded automatically when the server or bundled tclint changes
- Speed up TclOO completion, signature help, inlay hints, and Go to Definition by reusing the cached syntax tree and skipping files without classes
- Speed up references, document highlights, and call hierarchy with cached definition lookups
- Keep background indexing from blocking requests that need a fresh syntax tree
- Add Go to Definition for TclOO classes, constructors, and resolved methods, including PSC library definitions
- Index PSC layer scripts (including external paths and legacy Windows encoding) and share TclOO class metadata across files for completion, signatures, inlay hints, and highlighting
- Add document-local TclOO method completion for `new`/`create` instances, `my`, and statically inferred return chains
- Suggest TclOO class names as classes and semantically highlight their declarations and calls
- Show signature help and parameter inlay hints for resolved TclOO methods and constructors, including optional and variadic arguments
- Add incoming and outgoing call hierarchy for custom TCL procedures and MOM event handlers
- Add document highlights for procedure and variable occurrences
- Make completion context-aware and prioritize local, current-file, workspace, and built-in symbols
- Add command-aware completion for Tcl subcommands, fixed arguments, and valid options
- Add semantic argument completion for variables, procedures, namespaces, and local file paths
- Add placeholder-based snippets for common Tcl structures and `dict for`
- Integrate the NX Tcl Remote Debugger directly into NX Postprocessor Support
- Add `nx-tcl` attach configurations and breakpoint support for TCL and DEF files
- Support breakpoints, stepping, stack frames, variables, watches, evaluation, logpoints, hit conditions, and Tcl error stops
- Add generation-safe stack and variable references so delayed VS Code requests cannot address stale NX frames
- Add command-buffer breakpoint handling for `LIB_GE_command_buffer_edit_*` source bodies
- Extend the README with launch configuration, path mapping, and debugger usage
- Prevent truncated TCL inlay hints and add configurable parameter hint modes
- Add inlay hints for built-in NX procedures, variadic arguments, and visible ranges
- Add inlay hint documentation and navigation to custom procedure definitions
- Add signature help for custom TCL procedures and built-in NX/MOM procedures
- Clean stale TCL indexes on close, delete, and rename operations
- Make background parsing and index updates thread-safe
- Improve TCL response times with debounced edits and cached semantic, inlay, hover, completion, and variable indexes
- Debounce CDL/DEF diagnostics and remove per-line diagnostic logging
