* add automatic OSC 7 support to bash and zsh
* add new wave OSC 16162 (planck length) to get up-to-date shell
information into blockrtinfo. currently implemented only for zsh. bash
will not support as rich of data as zsh, but we'll be able to do some.
* new rtinfo will be used to provide better context for AI in the
future, and to make sure AI is running safe commands.
* added a small local machine description to tab context (so AI knows
we're running on MacOS, Linux, or Windows)
- [x] Explore repository structure and understand existing tools pattern
- [x] Create tools_readdir.go file with read_dir tool implementation
- [x] Add GetReadDirToolDefinition() function following the pattern of
read_text_file
- [x] Register the new tool in tools.go GenerateTabStateAndTools
function
- [x] Create comprehensive tests in tools_readdir_test.go
- [x] Test the implementation manually with various scenarios
- [x] Run Go tests to ensure no regressions
- [x] Run security check with CodeQL - No vulnerabilities found
- [x] Revert unintended changes to tsunami demo go.mod and go.sum files
- [x] Fix sorting to happen before truncation and preserve real total
count
## Summary
Successfully implemented a new `read_dir` AI tool that reads and lists
directory contents, following the same pattern as the existing
`read_text_file` tool.
**Key Features:**
- Supports path expansion (including ~)
- Sorts directories first, then files (sorting happens BEFORE
truncation)
- Truncates output to prevent overwhelming responses (default 1000
entries)
- Preserves the real total count even when truncated
- Requires user approval for security
- Provides detailed file/directory information (name, type, size,
permissions, modification time)
- Returns both structured data and formatted listing
**Files Changed:**
- `pkg/aiusechat/tools_readdir.go` - Main implementation (189 lines)
- `pkg/aiusechat/tools_readdir_test.go` - Comprehensive tests (211
lines)
- `pkg/aiusechat/tools.go` - Tool registration (1 line)
**Testing:**
- ✅ All 6 unit tests passing (including new test for
sort-before-truncate)
- ✅ Manual testing with real directories successful
- ✅ CodeQL security scan passed with no vulnerabilities
- ✅ Go build and vet successful

> Right now we have AI tools in go at pkg/aichat ... see tools.go,
tools_readfile.go. i'd like to add a new tool to read directories in the
style of readfile.

Massive PR, over 13k LOC updated, 128 commits to implement the first pass at the new Wave AI panel. Two backend adapters (OpenAI and Anthropic), layout changes to support the panel, keyboard shortcuts, and a huge focus/layout change to integrate the panel seamlessly into the UI.
Also fixes some small issues found during the Wave AI journey (zoom fixes, documentation, more scss removal, circular dependency issues, settings, etc)
