Projects and branches¶
This tutorial shows you how to register repos as projects and run tasks on feature branches without switching directories.
What you'll learn: How to target repos from anywhere with /project, and run on branches with @branch.
The problem¶
So far, Takopi runs in whatever directory you started it. If you want to work on a different repo, you have to:
- Stop Takopi
cdto the other repo- Restart Takopi
Projects fix this. Once you register a repo, you can target it from chat—even while Takopi is running elsewhere.
1. Register a project¶
Navigate to the repo and run takopi init:
cd ~/dev/happy-gadgets
takopi init happy-gadgets
Output:
saved project 'happy-gadgets' to ~/.takopi/takopi.toml
This adds an entry to your config (Takopi also fills in defaults like worktrees_dir, default_engine, and sometimes worktree_base):
[projects.happy-gadgets]
path = "~/dev/happy-gadgets"
Project aliases are also Telegram commands
The alias becomes a /command you can use in chat. Keep them short and lowercase: myapp, backend, docs.
2. Target a project from chat¶
Now you can start Takopi from another repo. If you don't specify a project, Takopi runs in the directory where you launched it.
cd ~/dev/your-project
takopi
And target the project by prefixing your message:
You
/happy-gadgets explain the authentication flow
Takopi runs the agent in ~/dev/happy-gadgets, not your current directory.
The response includes a context footer:
Takopi
ctx: happy-gadgets
codex resume abc123
That ctx: line tells you which project is active. When you reply, Takopi automatically uses the same project—you don't need to repeat /happy-gadgets.
3. Set up worktrees¶
Worktrees let you run tasks on feature branches without touching your main checkout. Instead of git checkout, Takopi creates a separate directory for each branch.
Add worktree config to your project:
[projects.happy-gadgets]
path = "~/dev/happy-gadgets"
worktrees_dir = ".worktrees" # where branches go
worktree_base = "main" # base for new branches
Ignore the worktrees directory
Add .worktrees/ to your global gitignore so it doesn't clutter git status:
echo ".worktrees/" >> ~/.config/git/ignore
4. Run on a branch¶
Use @branch after the project:
You
/happy-gadgets @feat/new-login add rate limiting to the login endpoint
Takopi:
1. Checks if .worktrees/feat/new-login exists (and is a worktree)
2. If the branch exists locally, it adds a worktree for it
3. If the branch doesn't exist, it creates it from worktree_base (or the repo default) and adds the worktree
4. Runs the agent in that worktree
The response shows both project and branch:
Takopi
ctx: happy-gadgets @feat/new-login
codex resume xyz789
Replies stay on the same branch. Your main checkout is untouched.
5. Context persistence¶
Once you've set a context (via /project @branch or by replying), it sticks:
You
/happy-gadgets @feat/new-login add tests
Takopi
ctx: happy-gadgets @feat/new-login
reply to the bot's answer
also add integration tests
Takopi
ctx: happy-gadgets @feat/new-login
The ctx: line in each message carries the context forward.
6. Set a default project¶
If you mostly work in one repo, set it as the default:
default_project = "happy-gadgets"
Now messages without a /project prefix go to that repo:
You
add a health check endpoint
Goes to happy-gadgets automatically.
Putting it together¶
Here's a typical workflow:
takopi
You
/happy-gadgets review the error handling
You
/happy-gadgets @feat/caching implement caching
Takopi
ctx: happy-gadgets @feat/caching
You
also add cache invalidation
You
/backend @fix/memory-leak profile memory usage
You
/happy-gadgets bump the version number
All from the same Telegram chat, without restarting Takopi or changing directories.
Project config reference¶
Full options for [projects.<alias>]:
| Key | Default | Description |
|---|---|---|
path |
(required) | Repo root. Expands ~. |
worktrees_dir |
.worktrees |
Where branch worktrees are created (relative to the project path). |
worktree_base |
null |
Base branch for new worktrees. If unset, Takopi uses origin/HEAD, the current branch, or master/main (in that order). |
default_engine |
null |
Engine to use for this project (overrides global default). |
chat_id |
null |
Bind a Telegram chat/group to this project. |
Troubleshooting¶
"unknown project"
Run takopi init <alias> in the repo first.
Branch worktree not created
Make sure the worktrees directory (default .worktrees) is writable. If you've customized worktrees_dir, verify that path exists or can be created.
Context not carrying forward
Make sure you're replying to a message with a ctx: line. If you send a new message (not a reply), context resets unless you have a default_project.
Worktree conflicts with existing branch
If the branch already exists locally, Takopi uses it. For a fresh start, delete the worktree and the branch, or pick a new branch name.
