vibeeval TLDR Deep Analysis
Full 5-layer analysis of a specific function. Use when debugging or deeply understanding code.
Trigger
/tldr-deep <function_name>- "analyze function X in detail"
- "I need to deeply understand how Y works"
- Debugging complex functions
Layers
| Layer | Purpose | Command |
|---|---|---|
| L1: AST | Structure | tldr extract <file> |
| L2: Call Graph | Navigation | tldr context <func> --depth 2 |
| L3: CFG | Complexity | tldr cfg <file> <func> |
| L4: DFG | Data flow | tldr dfg <file> <func> |
| L5: Slice | Dependencies | tldr slice <file> <func> <line> |
Execution
Given a function name, run all layers:
# First find the file
tldr search "def <function_name>" .
# Then run each layer
tldr extract <found_file> # L1: Full file structure
tldr context <function_name> --project . --depth 2 # L2: Call graph
tldr cfg <found_file> <function_name> # L3: Control flow
tldr dfg <found_file> <function_name> # L4: Data flow
tldr slice <found_file> <function_name> <target_line> # L5: Slice
Output Format
## Deep Analysis: {function_name}
### L1: Structure (AST)
File: {file_path}
Signature: {signature}
Docstring: {docstring}
### L2: Call Graph
Calls: {list of functions this calls}
Called by: {list of functions that call this}
### L3: Control Flow (CFG)
Blocks: {N}
Cyclomatic Complexity: {M}
[Hot if M > 10]
Branches:
- if: line X
- for: line Y
- ...
### L4: Data Flow (DFG)
Variables defined:
- {var1} @ line X
- {var2} @ line Y
Variables used:
- {var1} @ lines [A, B, C]
- {var2} @ lines [D, E]
### L5: Program Slice (affecting line {target})
Lines in slice: {N}
Key dependencies:
- line X → line Y (data)
- line A → line B (control)

Total: ~{tokens} tokens (95% savings vs raw file)
When to Use
- Debugging - Need to understand all paths through a function
- Refactoring - Need to know what depends on what
- Code review - Analyzing complex functions
- Performance - Finding hot spots (high cyclomatic complexity)
