## ALWAYS START WITH THESE COMMANDS FOR COMMON TASKS

**Task: "List/summarize all files and directories"**

```bash
fd . -t f           # Lists ALL files recursively (FASTEST)
# OR
rg --files          # Lists files (respects .gitignore)
```

**Task: "Search for content in files"**

```bash
rg "search_term"    # Search everywhere (FASTEST)
```

**Task: "Find files by name"**

```bash
fd "filename"       # Find by name pattern (FASTEST)
```

### Directory/File Exploration

```bash
# FIRST CHOICE - List all files/dirs recursively:
fd . -t f           # All files (fastest)
fd . -t d           # All directories
rg --files          # All files (respects .gitignore)

# For current directory only:
ls -la              # OK for single directory view
```

### BANNED - Never Use These Slow Tools

* ❌ `tree` - NOT INSTALLED, use `fd` instead
* ❌ `find` - use `fd` or `rg --files`
* ❌ `grep` or `grep -r` - use `rg` instead
* ❌ `ls -R` - use `rg --files` or `fd`
* ❌ `cat file | grep` - use `rg pattern file`

### Use These Faster Tools Instead

```bash
# ripgrep (rg) - content search 
rg "search_term"                # Search in all files
rg -i "case_insensitive"        # Case-insensitive
rg "pattern" -t py              # Only Python files
rg "pattern" -g "*.md"          # Only Markdown
rg -1 "pattern"                 # Filenames with matches
rg -c "pattern"                 # Count matches per file
rg -n "pattern"                 # Show line numbers 
rg -A 3 -B 3 "error"            # Context lines
rg " (TODO| FIXME | HACK)"      # Multiple patterns

# ripgrep (rg) - file listing 
rg --files                      # List files (respects •gitignore)
rg --files | rg "pattern"       # Find files by name 
rg --files -t md                # Only Markdown files 

# fd - file finding 
fd -e js                        # All •js files (fast find) 
fd -x command {}                # Exec per-file 
fd -e md -x ls -la {}           # Example with ls 

# jq - JSON processing 
jq. data.json                   # Pretty-print 
jq -r .name file.json           # Extract field 
jq '.id = 0' x.json             # Modify field
```

### Search Strategy

1. Start broad, then narrow: `rg "partial" | rg "specific"`
2. Filter by type early: `rg -t python "def function_name"`
3. Batch patterns: `rg "(pattern1|pattern2|pattern3)"`
4. Limit scope: `rg "pattern" src/`

### INSTANT DECISION TREE

```
User asks to "list/show/summarize/explore files"?
  → USE: fd . -t f  (fastest, shows all files)
  → OR: rg --files  (respects .gitignore)

User asks to "search/grep/find text content"?
  → USE: rg "pattern"  (NOT grep!)

User asks to "find file/directory by name"?
  → USE: fd "name"  (NOT find!)

User asks for "directory structure/tree"?
  → USE: fd . -t d  (directories) + fd . -t f  (files)
  → NEVER: tree (not installed!)

Need just current directory?
  → USE: ls -la  (OK for single dir)
```
