Tldr Deep

When you need to actually understand what a gnarly function is doing, this runs a five-layer analysis using the tldr CLI tool. It pulls AST structure, call graphs, control flow (including cyclomatic complexity), data flow analysis, and program slicing for dependencies. The output is formatted to show you everything from what calls what, to which variables affect which lines, to how complex the branching logic really is. Most useful when debugging something that doesn't make sense or preparing to refactor code you don't trust yet. It's basically the full forensic workup instead of just reading the source and hoping you caught everything.

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
