Rebrand: DeepSeek TUI → CodeWhale

Starting with v0.8.41, this project ships under a new name: codewhale.

This document explains what changed, what didn't, and how to migrate. None of the DeepSeek provider integration changed — only the local CLI / TUI brand.

TL;DR

# 1. Uninstall the old wrapper or binaries.
npm uninstall -g deepseek-tui      # or cargo uninstall deepseek-tui-cli deepseek-tui
                                    # or brew uninstall deepseek-tui

# 2. Install under the new name.
npm install -g codewhale            # or cargo install codewhale-cli codewhale-tui --locked
                                    # legacy Homebrew installs may still use
                                    # brew install deepseek-tui until the tap
                                    # formula is renamed.

# 3. Run with the new command.
codewhale doctor
codewhale

Your ~/.deepseek/config.toml, ~/.deepseek/sessions/, ~/.deepseek/skills/, ~/.deepseek/tasks/, and ~/.deepseek/mcp.json are untouched. Existing DEEPSEEK_* environment variables continue to work.

What got renamed

Surface	Before	After
CLI dispatcher binary	`deepseek`	`codewhale`
TUI runtime binary	`deepseek-tui`	`codewhale-tui`
npm wrapper package	`deepseek-tui`	`codewhale`
Crates.io crates	`deepseek-tui-cli` / `deepseek-tui` / `deepseek-*`	`codewhale-cli` / `codewhale-tui` / `codewhale-*`
Release assets	`deepseek-<platform>` / `deepseek-tui-<platform>`	`codewhale-<platform>` / `codewhale-tui-<platform>`
Checksum manifest	`deepseek-artifacts-sha256.txt`	`codewhale-artifacts-sha256.txt`

What did NOT change

Anything that targets the DeepSeek provider API stays exactly as it was:

Environment variables: DEEPSEEK_API_KEY, DEEPSEEK_BASE_URL, DEEPSEEK_MODEL, DEEPSEEK_PROVIDER, DEEPSEEK_PROFILE, DEEPSEEK_YOLO, DEEPSEEK_LOG_LEVEL, plus the existing DEEPSEEK_TUI_* runtime knobs (DEEPSEEK_TUI_BIN, DEEPSEEK_TUI_RELEASE_BASE_URL, etc.). They're kept for backward compatibility; renaming them would break every shell rc on the planet.
Model IDs: deepseek-v4-pro, deepseek-v4-flash, and the legacy aliases deepseek-chat and deepseek-reasoner.
Hosts: api.deepseek.com (global) and api.deepseeki.com (China fallback).
Config directory: ~/.deepseek/. Renaming this would invalidate every existing install's saved API key, sessions, skills, MCP config, and audit log.
GitHub repository URL: https://github.com/Hmbown/CodeWhale. The old Hmbown/DeepSeek-TUI URL redirects there during the transition.
Homebrew tap and formula (Hmbown/homebrew-deepseek-tui): still uses the legacy formula name for existing installs. Treat it as compatibility-only until the tap is renamed; new install docs prefer codewhale npm, Cargo, Docker, or direct downloads.
Docker image: ghcr.io/hmbown/codewhale.

Deprecation shims (through v0.8.x)

To keep existing shell aliases, scripts, and CI working through the rename, v0.8.41 and later v0.8.x releases ship deprecation shims:

A deepseek binary that prints a one-line warning to stderr and forwards argv to codewhale.
A deepseek-tui binary that does the same for codewhale-tui.
The legacy deepseek-tui npm package is deprecated and no longer receives new releases. Install the codewhale npm package instead.

These shims will be removed in v0.9.0. Please migrate before then.

Migrating in practice

npm

npm uninstall -g deepseek-tui
npm install -g codewhale

Cargo

cargo uninstall deepseek-tui-cli deepseek-tui 2>/dev/null || true
cargo install codewhale-cli codewhale-tui --locked

Or in a checkout:

cargo install --path crates/cli --locked --force
cargo install --path crates/tui --locked --force

Homebrew

The tap formula still installs through the legacy deepseek-tui name for existing Homebrew users. Keep using brew upgrade deepseek-tui only for that compatibility path. New installs should prefer npm, Cargo, Docker, or direct downloads until the formula and tap repo are renamed.

Manual / GitHub Releases

v0.8.41 Releases attach both the canonical codewhale-* / codewhale-tui-* assets and the legacy deepseek-* / deepseek-tui-* shim assets. Existing deepseek update invocations on v0.8.40 keep working; they land you on the deprecation shim, which then prompts the install of codewhale.

A second checksum manifest, deepseek-artifacts-sha256.txt, is attached as an alias of codewhale-artifacts-sha256.txt so v0.8.40's hardcoded lookup still verifies.

Why the name change

CodeWhale is a shorter, terminal-friendlier handle for the same terminal coding agent and the longer-term product direction: a DeepSeek-first agentic terminal for open source and open-weight coding models. The project name, command names, package names, release assets, Docker image, and CNB mirror move to CodeWhale; the official DeepSeek provider, model IDs, env vars, and ~/.deepseek/ config surface remain first-class.

Reporting issues with the rename

If your install broke during the migration, please open an issue at https://github.com/Hmbown/CodeWhale/issues and include:

The output of codewhale --version (or deepseek --version if you're still on the shim).
Which install path you used (npm, cargo, brew, manual).
The exact command you ran and the full error output.

We'll prioritize migration regressions.
