CodeWhale Bot 4bc02de37f docs(readme): replace the star-history chart with a live fan-out clip
GitHub restricted third-party access to star data, so the star-history
image at the bottom of the README no longer renders. Replace it with a
9-second clip of Codewhale fanning out three read-only scout subagents
(assets/fanout.gif, 960px, 2.3 MB).

# Codewhale
An open source coding agent for your terminal — bring your own model.
Codewhale started as a native experience for DeepSeek. It has since grown into a
community-driven project: one coding harness that fits a growing international
community and supports as many models and providers as possible — open models
first, hosted or local, none privileged over the rest.
Give it a provider, a model, and a task. It reads your code, edits files, runs
commands, and checks its own work, then stops when the job is done or it needs
you. Switch models mid-task with `/model`. Work interactively in the TUI, or run
`codewhale exec` in scripts and CI. It's written in Rust, licensed MIT, and runs
on your machine.
The part that isn't like other harnesses: **you pick the model for each role,
and they don't have to match.** A fleet pins a provider, a model, and a
reasoning tier per role — so a cheap fast model can direct an expensive
reasoning one, or a GLM builder can work the same job as a Kimi reviewer.
Write your own roles, your own constitution, and the harness is yours rather
than ours.
We're always looking for contributors and ways to improve. If a model or
provider you use is missing, or something breaks, telling us is one of the most
useful things you can do — see [Contributing](#contributing).

## Install
```bash
npm install -g codewhale
```
Cargo, Docker, Nix, Scoop, prebuilt archives, Android/Termux, and a CNB mirror
for anyone who can't reach GitHub are covered in
[docs/INSTALL.md](docs/INSTALL.md). Coming from `deepseek-tui`? Your config and
sessions carry over — see [docs/REBRAND.md](docs/REBRAND.md).
## Use
```bash
codewhale auth set --provider deepseek # or export ANTHROPIC_API_KEY, etc.
codewhale # open the TUI
codewhale exec "fix the failing test" # headless
codewhale web # local browser client on 127.0.0.1
```
In the TUI: `/model` switches provider and model together, `/fleet` builds and
runs the team — one role at a time, each with its own model — `/undo` reverts
the last turn, and `/restore <N>` rolls the workspace back to an earlier
snapshot (bare `/restore` lists them). `Tab`
cycles Plan / Work / Operate when the composer is empty — with text in it, `Tab`
completes slash commands and `@` mentions instead. `Shift+Tab` cycles the
Ask / Auto-Review / Full Access permission posture at any time. `!` runs a
shell command through the normal approval path.
## What it does
- **Any model, any provider — and any mix of them.** DeepSeek, Claude, GPT,
Kimi, GLM, and 30+ providers, plus your own vLLM, SGLang, or Ollama with no
key, all through one runtime and one toolset. The catalog tracks each
provider's live lineup — DeepSeek's V4 Pro backend (labeled
`DeepSeek-V4-Pro-0813`) stays callable as `deepseek-v4-pro`, Grok 4.6 is the
direct xAI default, and OrcaRouter routes through `orcarouter/auto`. A saved
role records its `provider`, `model`, and reasoning tier explicitly, so a
fleet can span vendors in a single run and a role's route never depends on
whichever provider happens to be active. Context limits and prices come from
the real route, and an unknown price shows as unknown rather than $0.
- **A harness you author.** Roles are files you can read and edit — a model, a
tool posture, and standing instructions per role — kept in the project so the
team shares them, or beside your other personal settings so they follow you
between repos. A constitution records how you want the agent to behave across
every session, so the harness matches your practice instead of ours.
- **Read-only until you allow more.** Plan mode can't change files, and
approvals gate risky commands. When an OS sandbox actually wraps a command,
Codewhale says so: Seatbelt on macOS where available, opt-in bubblewrap on
Linux. A repo's `constitution.json` compiles into write holds that even Full
Access can't skip.
- **Work you can resume.** A fleet records every step to an append-only ledger,
so `fleet resume` picks up where you left off.
