# ctask Project Guidelines

## Build and Install

This project is a local-only Go CLI. It is not published to any package registry or remote repository.

### Prerequisites

- Go 1.26+ (`winget install GoLang.Go`)
- just (optional task runner: `winget install Casey.Just`)

### Install on Windows

```powershell
cd C:\Users\Warren\claude_tasks\ctask_v0.1
powershell -NoProfile -ExecutionPolicy Bypass -File scripts/install.ps1
```

Or with just: `just install`

This builds from the local repo, copies files to `%LOCALAPPDATA%\ctask\bin`, and adds the directory to user PATH.

| Installed file | Location |
|---|---|
| ctask.exe | %LOCALAPPDATA%\ctask\bin\ctask.exe |
| ctask-statusline.sh | %LOCALAPPDATA%\ctask\bin\ctask-statusline.sh |
| ctask-statusline.ps1 | %LOCALAPPDATA%\ctask\bin\ctask-statusline.ps1 |

### Uninstall

```powershell
cd C:\Users\Warren\claude_tasks\ctask_v0.1
powershell -NoProfile -ExecutionPolicy Bypass -File scripts/uninstall.ps1
```

Or with just: `just uninstall`

Removes only ctask files and the PATH entry (if ctask install added it). Does NOT remove workspaces or task data.

### Dev build (no install)

```
just build    # or: go build -o ctask.exe .
just test     # or: go test ./... -v -count=1
```

### Remote install

Not available. There is no git remote configured. Do not provide `go install <module>@latest` commands.

## Repository and Package Identity

Never invent remote repository, package, or module identities. Do not guess GitHub usernames/orgs, repo URLs, Go module paths, release install commands, or package manager coordinates. Only provide remote clone/install/publish commands if they are verified from the actual repo config (e.g. `go.mod`, `git remote -v`) or explicitly provided by the user. If publishing/release details are not configured, say so plainly and provide local-only build/install commands instead.

### Bad vs Good

Bad: `go install github.com/someone/ctask@latest`
Bad: `git clone https://github.com/someone/ctask.git`

Good: `just install` or `powershell -File scripts/install.ps1`
Good: "This project is not published remotely. Build and install locally."

## Testing

```
just test
# or: go test ./... -v -count=1
```

## Data Safety

The `ctask delete` command has active-workspace protection:
1. Checks `CTASK_WORKSPACE` env var (catches same-session attempts)
2. Checks for `.ctask/manifest-start.json` (catches cross-terminal attempts)

Both checks run before any mutation. Any changes to the delete path must preserve this "refuse before mutate" invariant.
