vardoger
A cross-platform plugin for AI coding assistants (Cursor, Claude Code, OpenAI Codex, OpenClaw, GitHub Copilot CLI, Windsurf, Cline) that reads your conversation history, extracts behavioral patterns, and generates personalized system prompt additions — making the assistant progressively better suited to how you work.
All processing happens locally. No data ever leaves your machine.
Prerequisites
Python 3.11+
| Platform | Command |
|---|---|
| macOS | brew install python@3.13 (install Homebrew) or python.org/downloads/macos |
| Debian / Ubuntu | sudo apt install python3 |
| Fedora | sudo dnf install python3 |
| Windows | winget install Python.Python.3.13 or python.org/downloads/windows |
pipx
Recommended for installing vardoger as an isolated CLI tool. Full instructions at pipx.pypa.io/stable/installation.
| Platform | Command |
|---|---|
| macOS | brew install pipx && pipx ensurepath |
| Debian / Ubuntu | sudo apt install pipx && pipx ensurepath |
| Fedora | sudo dnf install pipx && pipx ensurepath |
| Windows | scoop install pipx or pip install --user pipx && pipx ensurepath |
Quick Start
pipx install vardoger
vardoger setup cursor # or claude-code, codex, openclaw, copilot, windsurf, cline
Then tell your assistant: "Personalize my assistant."

Previous pre-releases.
pipx install vardogernow resolves to the stable0.2.xline. The beta install paths below stay here for anyone still pinning an earlier release; new installs should not need them.# opt into future pre-releases (0.2.0bN, etc.): pipx install --pip-args="--pre" vardoger # or pin an older pre-release: pipx install vardoger==0.1.0b3 # or run without installing: uvx vardoger --help
CLI Commands
| Command | Purpose |
|---|---|
vardoger setup <platform> | Register vardoger with a platform (cursor, claude-code, codex, openclaw, copilot, windsurf, cline). |
vardoger status [--platform X] [--json] | Report whether each personalization is fresh or stale. |
vardoger prepare --platform X [--batch N] [--synthesize] | Produce the batched prompts used by the AI-driven skill pipeline. |
vardoger write --platform X | Read synthesized personalization from stdin and write it to the platform's rules file (supports YAML-frontmatter confidence metadata). |
vardoger feedback accept|reject --platform X [--reason TEXT] | Record whether you kept or rejected the last generation. reject auto-reverts to the prior generation. |
vardoger compare --platform X | --all [--window DAYS] [--json] | Compare heuristic conversation-quality metrics before vs. after the latest personalization. |
How It Works
- Read — Parses conversation history already stored on disk by each platform
- Analyze — The host AI model identifies patterns in your communication style, tech stack, workflow, and preferences
- Generate — Produces a system prompt addition tailored to you
- Deliver — Writes the addition to the platform's native config (
.cursor/rules/,.claude/rules/,AGENTS.md, etc.)
First run vs. incremental runs. By default vardoger does not apply a time window — the first run reads your full local history (that is when the signal is richest and a windowed default would silently drop older sessions you never get a second chance to feed in). After that, a per-conversation checkpoint store at
~/.vardoger/state.jsonensures every subsequent run only reprocesses new or changed conversations, so refreshes stay fast. If you have very large local history and want to cap the first-run cost, pass--since DAYS(e.g.vardoger prepare --platform cursor --since 90); use--fullto force a full re-crawl that bypasses the checkpoint.
Supported Platforms
| Platform | History Source | Prompt Delivery | Integration |

Quality gates
CI enforces a combined quality bar on every push and pull request:
ruff check/ruff format --check— lint (incl. complexity, pylint, return, pathlib, tryceratops rules) and formatting.mypy src/— strict type checking.pytest --cov=vardoger --cov-fail-under=80— tests across Python 3.11–3.13 with a combined 80% coverage floor.- A parallel security job runs
bandit -r src/andpip-audit --skip-editableto catch common code smells and dependency CVEs.
Run the full bundle locally before pushing:
uv run ruff check . && uv run ruff format --check . && uv run mypy src/ && uv run pytest --cov=vardoger --cov-fail-under=80
Contributing
Contributions are welcome. Short version:
- Fork
dstrupl/vardogeron GitHub and clone your fork. uv syncand create a topic branch.- Make your changes with tests and run the quality-gate one-liner above.
- Push to your fork and open a PR against
main.
CI (test on Python 3.11/3.12/3.13 plus a security job) will run automatically on the PR. First-time contributors may need a maintainer to click Approve and run before the first workflow execution.
See CONTRIBUTING.md for the full walkthrough and AGENTS.md for coding standards and commit-message conventions.
Releasing to PyPI
CI runs automatically on every push and PR (lint, type check, tests across Python 3.11–3.13). To publish a new version:
- Bump
versioninpyproject.toml - Commit and push to
main - Go to Releases > Create a new release
- Create a new tag matching the version (e.g.
v0.1.0), add a title and description - Click Publish release
The publish.yml workflow builds the package and uploads it to PyPI via trusted publishers (no API tokens needed). Once complete, pipx install vardoger will pull the new version.
Status
Public beta. The 0.3.x line is published on PyPI and actively maintained;
marketplace listings are rolling out per MARKETPLACE_STATUS.md.
See PRD.md for the full product requirements document.
