CLI Commands Navigation

File tree

tldr tree [path] tldr tree src/ --ext .py .ts # Filter extensions tldr tree . --show-hidden # Include hidden files

Code structure (codemaps)

tldr structure [path] --lang python tldr structure src/ --max 100 # Max files to analyze

Search

Text search

tldr search [path] tldr search "def process" src/ tldr search "class.*Error" . --ext .py tldr search "TODO" . -C 3 # 3 lines context tldr search "func" . --max 50 # Limit results

Semantic search (natural language)

tldr semantic search "authentication flow" tldr semantic search "error handling" --k 10 tldr semantic search "database queries" --expand # Include call graph

File Analysis

Full file info

tldr extract tldr extract src/api.py tldr extract src/api.py --class UserService # Filter to class tldr extract src/api.py --function process # Filter to function tldr extract src/api.py --method UserService.get # Filter to method

Relevant context (follows call graph)

tldr context --project tldr context main --project src/ --depth 3 tldr context UserService.create --project . --lang typescript

Flow Analysis

Control flow graph (complexity)

tldr cfg tldr cfg src/processor.py process_data

Returns: cyclomatic complexity, blocks, branches, loops

Data flow graph (variable tracking)

tldr dfg tldr dfg src/processor.py process_data

Returns: where variables are defined, read, modified

Program slice (what affects line X)

tldr slice tldr slice src/processor.py process_data 42 tldr slice src/processor.py process_data 42 --direction forward tldr slice src/processor.py process_data 42 --var result

Codebase Analysis

Build cross-file call graph

tldr calls [path] tldr calls src/ --lang python

Reverse call graph (who calls this function?)

tldr impact [path] tldr impact process_data src/ --depth 5 tldr impact authenticate . --file auth # Filter by file

Find dead/unreachable code

tldr dead [path] tldr dead src/ --entry main cli test_ # Specify entry points tldr dead . --lang typescript

Detect architectural layers

tldr arch [path] tldr arch src/ --lang python

Returns: entry layer, middle layer, leaf layer, circular deps

Import Analysis

Parse imports from file

tldr imports tldr imports src/api.py tldr imports src/api.ts --lang typescript

Reverse import lookup (who imports this module?)

tldr importers [path] tldr importers datetime src/ tldr importers UserService . --lang typescript

Quality & Testing

Type check + lint

tldr diagnostics tldr diagnostics src/api.py tldr diagnostics . --project # Whole project tldr diagnostics src/ --no-lint # Type check only tldr diagnostics src/ --format text # Human-readable

Find affected tests

tldr change-impact [files...] tldr change-impact # Auto-detect (session/git) tldr change-impact src/api.py # Explicit files tldr change-impact --session # Session-modified files tldr change-impact --git # Git diff files tldr change-impact --git --git-base main # Diff against branch tldr change-impact --run # Actually run affected tests

Caching

Pre-build call graph cache

tldr warm tldr warm src/ --lang python tldr warm . --background # Build in background

Build semantic index (one-time)

tldr semantic index [path] tldr semantic index . --lang python tldr semantic index . --model all-MiniLM-L6-v2 # Smaller model (80MB)

Daemon (Faster Queries)

The daemon holds indexes in memory for instant repeated queries.

Daemon Commands

Start daemon (backgrounds automatically)

tldr daemon start tldr daemon start --project /path/to/project

Check status

tldr daemon status

Stop daemon

tldr daemon stop

Send raw command

tldr daemon query ping tldr daemon query status

Notify file change (for hooks)

tldr daemon notify tldr daemon notify src/api.py

Daemon Features Feature Description Auto-shutdown 30 minutes idle Query caching SalsaDB memoization Content hashing Skip unchanged files Dirty tracking Incremental re-indexing Cross-platform Unix sockets / Windows TCP Daemon Socket Protocol

Send JSON to socket, receive JSON response:

// Request

// Response

All 22 daemon commands:

ping, status, shutdown, search, extract, impact, dead, arch, cfg, dfg, slice, calls, warm, semantic, tree, structure, context, imports, importers, notify, diagnostics, change_impact

Semantic Search (P6)

Natural language code search using embeddings.

Setup

Build index (downloads model on first run)

tldr semantic index .

Default model: bge-large-en-v1.5 (1.3GB, best quality)

Smaller model: all-MiniLM-L6-v2 (80MB, faster)

tldr semantic index . --model all-MiniLM-L6-v2

Search tldr semantic search "authentication flow" tldr semantic search "error handling patterns" --k 10 tldr semantic search "database connection" --expand # Follow call graph

Configuration

In .claude/settings.json:

{ "semantic_search": { "enabled": true, "auto_reindex_threshold": 20, "model": "bge-large-en-v1.5" } }

TLDR respects .tldrignore (gitignore syntax):

.tldrignore

.venv/ pycache/ node_modules/ *.min.js dist/

First run creates .tldrignore with sensible defaults. Use --no-ignore to bypass.

When to Use TLDR vs Other Tools Task Use TLDR Use Grep Find function definition tldr extract file --function X - Search code patterns tldr search "pattern" - String literal search - grep "literal" Config values - grep "KEY=" Cross-file calls tldr calls - Reverse deps tldr impact func - Complexity analysis tldr cfg file func - Variable tracking tldr dfg file func - Natural language query tldr semantic search - Python API from tldr.api import ( # L1: AST extract_file, extract_functions, get_imports, # L2: Call Graph build_project_call_graph, get_intra_file_calls, # L3: CFG get_cfg_context, # L4: DFG get_dfg_context, # L5: PDG get_slice, get_pdg_context, # Unified get_relevant_context, # Analysis analyze_dead_code, analyze_architecture, analyze_impact, )

Example: Get context for LLM

ctx = get_relevant_context("src/", "main", depth=2, language="python") print(ctx.to_llm_string())

Bug Fixing Workflow (Navigation + Read)

Key insight: TLDR navigates, then you read. Don't try to fix bugs from summaries alone.

The Pattern

1. NAVIGATE: Find which files matter

tldr imports file.py # What does buggy file depend on? tldr impact func_name . # Who calls the buggy function? tldr calls . # Cross-file edges (follow 2-hop for models)

2. READ: Get actual code for critical files (2-4 files, not all 50)

Use Read tool or tldr search -C for code with context

tldr search "def buggy_func" . -C 20

Why This Works

For cross-file bugs (e.g., wrong field name, type mismatch), you need to see:

The file with the bug (handler accessing task.user_id) The file with the contract (model defining owner_id)

TLDR finds which files matter. Then you read them.

Getting More Context

If TLDR output isn't enough:

tldr search "pattern" . -C 20 - Get actual code with 20 lines context tldr imports file.py - See what a file depends on Read the file directly if you need the full implementation Token Savings Evidence Raw file read: 23,314 tokens TLDR all layers: 1,189 tokens ───────────────────────────────── Savings: 95%

The insight: Call graph navigates to relevant code, then layers give structured summaries. You don't read irrelevant code.
