toks 0.2.0

Count tokens for files across LLM providers from the command line

toks

Count tokens for files and directories across LLM providers. See how much of a model's context window your content will consume before you spend the tokens.

Installation

pip install toks

Or with uv:

uv tool install toks

The ct shorthand alias is also available — ct src/ is equivalent to toks src/.

Quick Start

1. Configure your providers

toks setup

The interactive wizard walks you through selecting providers, entering API keys, and choosing models.

2. Count tokens

# Single file
toks src/main.py --for claude

# Entire directory with glob filter
toks src/ --for claude --glob "*.py"

# Quiet mode (just the number)
toks README.md --for claude -q

# Pipe from stdin
cat file.py | toks - --for claude

Output

Provider: claude (claude-opus-4-6)

Total: 17,911 tokens
  Agent (1M):  1.8%
  Web (200K):    9.0%
  API (1M):    1.8%

Three percentage columns show context window usage for each provider's interfaces: coding agent, web chat, and API. The Agent and Web columns populate when you configure your plan and coding agent model via toks setup.

Supported Providers

Provider	Text	Images	PDF	Office Docs
Claude (Anthropic)	Yes	JPEG, PNG, GIF, WebP	Yes	No
OpenAI	Yes	JPEG, PNG, GIF, WebP	Yes	DOCX, XLSX, PPTX
Gemini (Google)	Yes	JPEG, PNG, GIF, WebP + more	Yes	No
Grok (xAI)	Yes	JPEG, PNG (local calc)	No	No

All token counting is done via each provider's REST API. No local tokenizer libraries are needed.

Configuration

Config files live in ~/.config/toks/:

• config.toml -- provider settings, default model, plan tier
• .env -- API keys

Re-run toks setup at any time to update your configuration.

Commands

toks <target> [options]    # Count tokens (default command)
toks setup                 # Interactive configuration wizard
toks models --refresh      # List known models / refresh registry

ct can be used anywhere in place of toks.

Options

--max-size <size>	Exclude files larger than size (default: 50MB)
--depth <n>	Limit directory recursion depth (0 = target dir only)
-q / --quiet	Output only the total token count
--summary	Totals without the tree
--no-progress	Suppress progress bar
--concurrency <n>	Concurrent API requests (default: 10)
--retries <n>	Retry count for transient errors (default: 3)
