• There are 13 files with 1,622 lines of code.
• 0 very long files (0 lines of code)
• 1 long files (521 lines of code)
• 2 medium size files (421 lines of code)
• 3 small files (394 lines of code)
• 7 very small files (286 lines of code)

File	# lines	≈ tokens to read	# changes (1y)	≈ lines edited per change	lines read per line changed
lib.rs in src	521	~3k–10k	1	~70	~7
core.py in tiktoken	211	~1k–3k	1	~15	~15
load.py in tiktoken	122	~700–2k	1	~15	~10
model.py in tiktoken	81	~500–1.5k	1	~10	~7
__init__.py in tiktoken	6	under 1k	2	~2	~3

Tokens are lines × 7 to 14 (analysis.fileReadsForChanges). Lines edited per change are the file's lines added and deleted divided by its commits over the whole history. Agents read about 2,000 lines at a time: when a 17,000-line file was split into modules, the tokens an agent read for the same change fell by 83% (The Economic Benefit of Refactoring, 2026).

There is only one file with lines longer than 120 characters. In total, there is only one long line.

• File size measurements show the distribution of size of files.
• Files are classified in four categories based on their size (lines of code): 1-100 (very small files), 101-200 (small files), 201-500 (medium size files), 501-1000 (long files), 1001+(very long files).
• It is a good practice to keep files small. Long files may become "bloaters", code that have increased to such gargantuan proportions that they are hard to work with.
