# TeamCity CLI (`teamcity`)

## Quick Start

```bash
teamcity auth status                    # Check authentication
teamcity run list --status failure      # Find failed builds
teamcity run log <id> --failed --raw    # Full failure diagnostics
```

**Do not guess flags or syntax.** Use the [command reference](references/commands.md) or `teamcity <command> --help`. Builds are **runs** (`teamcity run`); build configurations are **jobs** (`teamcity job`). Never use `--count` — use `--limit` (or `-n`).

## Gotchas

- **Composite builds have empty logs** — drill into child builds for the actual failure.
- **Build chains fail bottom-up** — deepest failed dependency is the root cause. Use `teamcity run tree <id>`.
- **`--local-changes` excludes Kotlin DSL** — push `.teamcity/` changes before running.
- **`TEAMCITY_URL` alone bypasses stored auth** — set both `TEAMCITY_URL` and `TEAMCITY_TOKEN`, or leave unset.
- **Logs**: use `--raw` and dump to a temp file. **Builds**: use `--watch` when starting them.
- **VCS triggers aren't always wired up** — after pushing a fix you may need to start builds manually.
- **`pipeline push` does not validate** — always `teamcity pipeline validate` first.
- **GitHub VCS roots: use a GitHub App connection.** Never paste a PAT via `--auth password`. See [workflows](references/workflows.md).

## Quick Workflows

See [Workflows](references/workflows.md) for full details on each.

- **Investigate failure**: `run list --status failure` → `run log <id> --failed --raw` → `run tests <id> --failed`
- **Debug build chain**: `run tree <id>` → drill to deepest failed child
- **Fix and verify**: edit → push → `run start --watch` (use `--local-changes` for personal builds)
- **Pipeline lifecycle**: `pipeline pull <id>` → edit → `pipeline validate` → `pipeline push <id>`, `pipeline schema` to get the actual schema from the server
- **GitHub VCS**: `connection create github-app` → `connection authorize` → install App on repo → `vcs create --auth token --connection-id <id>`
- **Docker registry**: `echo $TOKEN | connection create docker -p <id> --name X --url https://ghcr.io --username U --stdin`
