Project Instructions

Development Workflow

• Add all significant prompts (user messages) to prompts.md, organized by date
• Include prompts.md changes in git commits
• Significant prompts are those that request features, bug fixes, or architectural changes
• Exclude trivial prompts like "commit and push" or "fix typo"
• ALWAYS reload VS Code window automatically after each significant code change (compile, edit) using:

osascript <<'EOF'
tell application "Visual Studio Code"
    activate
    delay 0.1
end tell

tell application "System Events"
    tell process "Visual Studio Code"
        keystroke "p" using {command down, shift down}
        delay 0.1
        keystroke "Developer: Reload Window"
        delay 0.1
        keystroke return
    end tell
end tell
EOF

Architecture Notes

Method Discovery for Structs

The extension displays methods for Rust structs using the following approach:

1. Use VS Code's definition provider to find the struct definition location
2. Extract the actual struct name from the definition (handle type aliases by scanning forward)
3. Use grep to search for impl blocks for that struct
4. Parse function declarations from impl blocks to extract full method signatures
5. Extract documentation from /// comments (first paragraph, up to 3 lines)
6. Display methods with signatures as clickable links and docs below

Grep output format: filename.rs: or filename.rs- prefix must be stripped before parsing.

This approach works for both local structs and external crate types (e.g., DateTime from the time crate).
