tktop 1.1.0

Token monitor for coding agents — like htop for AI spend

tktop

Token monitor for coding agents. Like htop for your AI spend.

Features

• Live dashboard — real-time token usage breakdown (input/output/cache)
• Token flow graph — sparkline showing output tokens per turn
• Tool stats — see which tools consume the most calls
• Drift detection — 9 algorithms detecting loops, thrashing, runaway sessions
• Cost tracking — per-session cost estimates by model
• Turn drill-down — inspect individual turns with token split and content preview
• Coach screen — local feedback on prompt scope, validation habits, checkpoints, and agent workflow smells
• LLM analysis — on-demand optimization suggestions via Ollama/Anthropic/Vertex AI/OpenAI

Install

Requires Python 3.10 or newer.

# From PyPI
pip install tktop

# Upgrade to the latest release
pip install -U tktop

Usage

tktop              # launch interactive session list
tktop -h           # show help
tktop -v           # show version
tktop info         # print environment summary for bug reports
tktop doctor       # diagnose local setup

tktop doctor checks the settings file, Claude/Codex data directories, adapter discovery, and selected LLM provider configuration without contacting external LLM APIs.

Coach And LLM Analysis

The Coach screen is available from a session dashboard with c. It renders a scrollable Markdown report with local, deterministic guidance about how the developer used the coding agent: prompt scope, validation requests, checkpoint habits, exploration before edits, and repeated tool usage.

Coach does not call an LLM by default. Press L inside Coach to enhance the local findings with the configured analysis provider and model. Enhanced suggestions are cached in memory for the running TUI session, so leaving and reopening Coach shows the same result until the session changes, the app closes, or you regenerate it.

LLM analysis remains available from a session dashboard with a. Analysis focuses on token, cost, drift, and tool optimization; Coach focuses on improving developer workflow with agentic coding tools.

The settings file is created at ~/.tktop/settings.json the first time tktop loads its configuration. View its path and resolved values with:

tktop config path
tktop config show

Example configuration:

{
  "session_adapter": "auto",
  "default_provider": "ollama",
  "ui": {
    "show_token_flow": false
  },
  "agents": {
    "claude": {
      "dir": "~/.claude"
    },
    "codex": {
      "dir": "~/.codex"
    }
  },
  "providers": {
    "ollama": {
      "host": "http://localhost:11434",
      "model": "llama3"
    },
    "anthropic": {
      "api_key": "",
      "model": "claude-sonnet-4-6"
    },
    "vertex": {
      "project": "",
      "region": "us-east5",
      "model": "claude-sonnet-4-6"
    },
    "openai": {
      "base_url": "https://api.openai.com/v1",
      "api_key": "",
      "model": "gpt-4o"
    }
  }
}

session_adapter accepts auto, claude, or codex. Supported analysis providers are ollama, anthropic, vertex, and openai.

Environment variables override settings.json. Common overrides are:

TKTOP_SESSION_ADAPTER=codex
TKTOP_CODEX_DIR=~/.codex
TKTOP_LLM_PROVIDER=openai
TKTOP_OPENAI_API_KEY=sk-...
TKTOP_OPENAI_MODEL=gpt-4o

For source checkouts, .env.example lists all supported environment variables. Prefer environment variables for API keys instead of storing secrets in JSON.

Development

make install  # install in dev mode
make test     # run tests
make clean    # clean build artifacts

Local development still uses an editable install:

pip install -e ".[dev]"

Use these commands while developing:

make run           # run directly from the editable source checkout
make check         # lint, security scan, and full tests
make package-test  # build and install the wheel in an isolated local venv
make package-run   # launch the locally built wheel

make package-test uses .venvs/package-test, which is ignored by git. It tests the same wheel artifact that would be uploaded to PyPI, without publishing anything.

For maintainers, a versioned release can be prepared with:

make release VERSION=0.1.1

Devbox

If you have the Devbox CLI installed, you can bootstrap the repo with:

devbox shell

On first entry, the shell creates .venv, installs .[dev], and activates the environment for the session.
