You are a principal Python software engineer resolving a repository issue in `/workspace`.
Your sole objective is to produce a minimal, root-cause source patch that passes every hidden fail-to-pass and pass-to-pass regression test on the first grading run.

## Critical Environment & Grader Rules
1. **Air-Gapped Sandbox & Available CLI Tools**: No network access. Never run `pip`, `uv`, `conda`, or `git fetch`. Note: `rg` (`ripgrep`) is NOT installed in the container — always use `grep -rn --include="*.py"` for fast exact searches so you never waste a tool call on `command not found`.
2. **Protected Grading Paths**: Before running official verification, the grading harness **strips and reverts all changes** to `tests/`, `test/`, `testing/`, `test_*.py`, `*_test.py`, `conftest.py`, `pyproject.toml`, `setup.cfg`, `pytest.ini`, and `tox.ini`. Every part of your fix MUST reside in non-test production source files.
3. **Untracked File Trap (`git add -N .`)**: `submit_patch` stages ALL untracked files inside `/workspace`! Never leave reproduction or scratch files inside `/workspace` — run reproductions inline via `python3 - <<'PY'` or inside `/tmp/repro.py` in a single `run_command`.
4. **Stdout Truncation Rule**: `run_command` truncates stdout after the first 5,000 characters from the TOP. Always run pytest quietly with short tracebacks:
`pytest path/to/test_file.py -k pattern -q --tb=short --no-header`
If a test file is large, redirect output to `/tmp/pytest.log` and inspect `tail -n 80 /tmp/pytest.log` so failure tracebacks at the bottom are never cut off.
5. **Strict Pacing Discipline**: `get_status` and `submit_patch` are free and do NOT count toward `max_tool_calls`. Target **16-22 counted tool calls total**, and **begin your first `edit_file` change no later than tool call 15**. Reserve at least 4 calls for verification, `git status --short && git diff`, and submission.

## Execution Protocol

### Phase 1 — Pinpoint Code & Tests Immediately (1-2 tool calls)
- The user message already contains `Workspace Layout` — do NOT waste a turn running `ls` on top-level directories.
- Run a single compound `run_command` with `grep -rn --include="*.py"` to locate:
(a) the exact symbols, error strings, or functions from the problem description,
(b) **all parallel or sibling implementations** (for example sync + async variants, `Client` + `AsyncClient`, serializer + deserializer, multiple backends/dialects, base + subclass methods, `__init__.py` / `__all__` exports), and
(c) the closest existing unit test files under `tests/`.

### Phase 2 — Deep Read & Spec Anchor (2-5 tool calls)
- Use `read_file` with generous `start_line` and `end_line` windows (180-300 lines per call so you read whole modules in fewer calls) on the target function/class, callers, type annotations, and neighboring tests.
- Before editing, verify every explicit and implicit requirement from the issue: exact parameter names, defaults, boundary/domain edge cases, exception types/messages, `None` vs empty collection vs falsy (`0`, `False`, `""`) semantics, mutability/copying, and return types.

### Phase 3 — Reproduce Bug in One Call (1 tool call)
- Run ONE concise command (`python3 - <<'PY' ... PY` or targeted `pytest ... -q --tb=short --no-header`) via `run_command` to observe the exact pre-fix failure. Do NOT spend multiple tool calls writing separate reproduction scripts.

### Phase 4 — Surgical Implementation Across All Parallel Paths (1-4 tool calls)
- Begin editing by tool call 15! Use `edit_file` with 4-6 lines of exact surrounding context copied from `read_file`.
- Update ALL parallel codepaths (sync/async, multiple classes/dialects, type hints) consistently so partial fixes do not fail sibling tests.
- **2-Strike Edit Rule**: If `edit_file` fails twice on the same block due to whitespace or escaping, do not retry `edit_file` a third time — apply an atomic Python transformation via `run_command` and immediately verify `python3 -m py_compile path/to/file.py`.

### Phase 5 — Edge-Case Verification, Diff Hygiene & Clean Exit (2-4 tool calls)
- Run a single compound `run_command` testing both your reproduction + boundary edge cases (`None`, empty input, leading/trailing delimiters, subdomain/prefix boundaries, subclass/async parity) AND the relevant existing `pytest` module(s) with `-q --tb=short --no-header`.
- Run `git status --short && git diff` via `run_command`. Confirm:
- ZERO untracked (`??`) files in `/workspace` (`rm -f` any untracked workspace files immediately),
- ZERO modifications to `tests/` or protected config files (`git checkout -- tests/` if touched),
- Minimal, clean diff with valid imports and indentation.
- Call `submit_patch` once verification passes, then respond with a brief 2-sentence plain-text summary and make NO further tool calls.

The user is reporting a `TypeError: can only concatenate str (not "bytes") to str` in `skipper/cli.py` at line 117, specifically in the `build` function.
The offending line is `fqdn_image = image + ':' + tag`.
This indicates that either `image` or `tag` (or both) is of type `bytes` instead of `str`.

Let's start by examining `skipper/cli.py` around line 117.

The error is at line 117 (relative to the original trace) or line 117-120 approx in the read file.
The line is `fqdn_image = image + ':' + tag`.
In the provided snippet, `image` comes from `valid_images_to_build`, and `tag` comes from `git.get_hash()`.

Let's check where `valid_images` comes from and what `git.get_hash()` returns.
`tag = git.get_hash()` is called just before the loop.

Let's examine `skipper/git.py` to see what `get_hash()` returns.

`subprocess.check_output(git_command).strip()` returns `bytes` in Python 3.
`git.get_hash()` is returning `bytes`.
`image` is likely a `str` (since it comes from config/valid_images).
So `image + ':' + tag` fails because `image` is `str` and `tag` is `bytes`.

The fix should be to decode the result of `subprocess.check_output` in `skipper/git.py`.

Wait, the problem description shows:
`WARNING:root:*** Uncommitted changes present - Build container version might be outdated ***`
This warning comes from `git.get_hash()`'s call to `uncommitted_changes()`.

Let's verify this by creating a reproduction script.
I need to simulate a git repository or just mock `subprocess.check_output`.
Actually, since I'm in a git repo (likely), I can just run a script that calls `skipper.git.get_hash()`.

However, I can just test it with a small script.

Confirmed. `git.get_hash()` returns `bytes`.

I should fix this in `skipper/git.py`.
The best way to handle this in Python 3 is to use `universal_newlines=True` or `.decode('utf-8')`.
Since `subprocess.check_output` is used, `universal_newlines=True` (or `text=True` in newer Python versions) would return a string.
Alternatively, I can call `.decode()` on the result.

Looking at `skipper/git.py`:
```python
    return subprocess.check_output(git_command).strip()
```

I'll change it to:
```python
    return subprocess.check_output(git_command, universal_newlines=True).strip()
```
Or:
```python
    return subprocess.check_output(git_command).decode('utf-8').strip()
```

Since this is a legacy project (using `six`), maybe they want compatibility? But the error is specifically a Python 3 `TypeError`.

Let's check if `universal_newlines` is available in the Python 3 version they are using (3.9 according to the traceback). Yes it is.

Wait, let's see if there are any other places where `subprocess.check_output` is used.

In `skipper/utils.py`:
`return str(subprocess.check_output(cmd).strip())`
In Python 3, `str(b'foo')` returns `"b'foo'"` (the string representation of the bytes object), which is probably not what they want if they want the actual string. But let's check that file too.

If `run_container_command` is used for something that expects a string, it might be returning `"b'something'"` currently.
However, the reported issue is specifically about `get_hash()` in `cli.py`.

Let's fix `skipper/git.py` first.

Wait, if I use `universal_newlines=True`, it should be fine. Or `.decode('utf-8')`.

Let's check `skipper/git.py` again.
```python
def get_hash(short=False):
    # ...
    return subprocess.check_output(git_command).strip()
```

I will change it to:
```python
    return subprocess.check_output(git_command).decode('utf-8').strip()
```

Wait, let's see if there are other places in `skipper/cli.py` that use `tag`.
Line 117: `fqdn_image = image + ':' + tag`
Line 123: `command = ['build', '--network=host', '--build-arg', f'TAG={tag}',`

Wait, `f'TAG={tag}'` in Python 3 would work even if `tag` is bytes?
No, it would result in `TAG=b'...'`.

Let's test that.

Exactly. So it would produce an incorrect tag in the build command too.

So fixing it in `git.get_hash()` is the right approach.

Now, should I also fix `skipper/utils.py`'s `run_container_command`?
The problem statement only mentioned `skipper build cmd`.

Let's see where `run_container_command` is used.

In `skipper/utils.py`, it's used in several places.
Let's check if those places use the return value.

`skipper/utils.py:55: output = run_container_command(command)`
`skipper/utils.py:79: output = run_container_command(command + [image])`

If `run_container_command` returns `str(bytes)`, and it was meant to return the string content, then it's also bugged.
But the prompt only specifies "can't build skipper (skipper build cmd)".

However, for completeness, if I see the same pattern of `subprocess.check_output(cmd).strip()` being converted to `str()` or not, I should probably fix it.

But let's focus on the reported bug first.

Let's apply the fix to `skipper/git.py`.

Around line 76:
`ctx.obj['build_container_tag'] = git.get_hash() if ctx.obj['git_revision'] else build_container_tag`
This value is stored in `ctx.obj`. I should check where `ctx.obj['build_container_tag']` is used.

And around line 156:
`tag = git.get_hash()`
This is used in `push` command. Let's see what happens next.

If `tag` was bytes, this would also fail here. So my fix to `git.get_hash()` is correct and covers both `build` and `push`.

Line 398: `tagged_image_name = image + ':' + tag`
Again, if `tag` (which comes from `ctx.obj['build_container_tag']`) is bytes, this would fail.
So my fix in `git.py` fixes all of these.

I should also consider if `run_container_command` in `utils.py` needs fixing.
`return str(subprocess.check_output(cmd).strip())`
If `subprocess.check_output(cmd)` returns `b'foo\n'`, `strip()` makes it `b'foo'`, and `str()` makes it `"b'foo'"`.
This is almost certainly a bug too.

Let's see if I should fix it. The task is "can't build skipper". Fixes to `git.get_hash()` solve that.
If I fix `run_container_command`, I might be fixing things not related to the issue, but it's clearly wrong.

However, looking at the "Strict Pacing Discipline", I should move towards submission.

Let's verify if there are any other `subprocess.check_output` calls I missed.
I ran `grep -rn "subprocess.check_output" skipper/` and got two results.

1. `skipper/utils.py:186:    return str(subprocess.check_output(cmd).strip())`
2. `skipper/git.py:19:    return subprocess.check_output(git_command).strip()`

I've fixed #2.
For #1, I'll check if it's actually causing issues or if it's usage is such that it doesn't matter (e.g. just logging).
In `skipper/runner.py`, `run_container_command` is used:
`utils.run_container_command(['network', 'create', net])`
`utils.run_container_command(['network', 'rm', net])`
`result = utils.run_container_command(cmd)`
And `result` is returned:
```python
    result = utils.run_container_command(cmd)
    # ... (some other stuff)
    return result
```
Wait, `runner.run` might be using this. Let's check `skipper/runner.py`.

In `_network_exists`:
`result = utils.run_container_command(cmd)`
`return net in result`
If `result` is `"b'network-name'"`, then `net in result` will still be True. So it might "work" by accident.

But it's still bad practice. Should I fix it? The prompt says "minimal, root-cause source patch". The root cause of the reported issue is in `git.py`.

If I fix `utils.py` as well, it's more thorough. Let's see if I have time/budget.
I've used about 10 tool calls. I have plenty.

Let's fix `skipper/utils.py` as well to be safe, as it's clearly the same pattern.
Wait, `str(subprocess.check_output(cmd).strip())` can be fixed to `subprocess.check_output(cmd).decode('utf-8').strip()`.

Actually, I should check if I should use `.decode('utf-8')` or `universal_newlines=True`.
`universal_newlines=True` is generally preferred in Python 3 for `subprocess`.

Let's look at `skipper/git.py` again.
```python
    return subprocess.check_output(git_command).decode('utf-8').strip()
```
This is fine.

For `skipper/utils.py`:
```python
    return str(subprocess.check_output(cmd).strip())
```
I'll change it to:
```python
    return subprocess.check_output(cmd).decode('utf-8').strip()
```

Wait, if I change `run_container_command` in `utils.py`, I should make sure I don't break anything that expects the `b'...'` string representation. But that's unlikely.

Let's check `skipper/utils.py` again.

Line 40: `output = check_output("echo " + match, shell=True).strip().decode("utf-8")`
This one is already calling `.decode("utf-8")`. So it's correct.

I'm confident in the fixes.
I'll run one final check to make sure `git.get_hash()` behaves as expected.

Wait, `git.get_hash(short=False)`. What if `short=True`?
```python
def get_hash(short=False):
    # ...
    git_command = ['git', 'rev-parse']
    if short:
        git_command += ['--short']
    git_command += ['HEAD']
    # ...
    return subprocess.check_output(git_command).decode('utf-8').strip()
```
This should also work correctly.

Final check of my changes:
1. `skipper/git.py`: `subprocess.check_output(git_command).strip()` -> `subprocess.check_output(git_command).decode('utf-8').strip()`
2. `skipper/utils.py`: `str(subprocess.check_output(cmd).strip())` -> `subprocess.check_output(cmd).decode('utf-8').strip()`

Both fix the Python 3 `bytes` vs `str` issue when interacting with `subprocess.check_output`.

The `TypeError: can only concatenate str (not "bytes") to str` was caused by `subprocess.check_output()` returning `bytes` in Python 3, which were then concatenated with strings in `skipper/cli.py` (via `skipper/git.py`) and improperly converted to strings in `skipper/utils.py`.

`subprocess.check_output(git_command).strip()` returns `bytes` in Python 3.
`git.get_hash()` is returning `bytes`.
`image` is likely a `str` (since it comes from config/valid_images).

Confirmed. `git.get_hash()` returns `bytes`.

I should fix this in `skipper/git.py`.
The best way to handle this in Python 3 is to use `universal_newlines=True` or `.decode('utf-8')`.
Since `subprocess.check_output` is used, `universal_newlines=True` (or `text=True` in newer Python versions) would return a string.
Alternatively, I can call `.decode()` on the result.

```python
    return subprocess.check_output(git_command).strip()

Line 398: `tagged_image_name = image + ':' + tag`
Again, if `tag` (which comes from `ctx.obj['build_container_tag']`) is bytes, this would fail.
So my fix in `git.py` fixes all of these.

I should also consider if `run_container_command` in `utils.py` needs fixing.
`return str(subprocess.check_output(cmd).strip())`
If `subprocess.check_output(cmd)` returns `b'foo\n'`, `strip()` makes it `b'foo'`, and `str()` makes it `"b'foo'"`.
This is almost certainly a bug too.

Let's see if I should fix it. The task is "can't build skipper". Fixes to `git.get_hash()` solve that.
If I fix `run_container_command`, I might be fixing things not related to the issue, but it's clearly wrong.

However, looking at the "Strict Pacing Discipline", I should move towards submission.

Let's verify if there are any other `subprocess.check_output` calls I missed.
I ran `grep -rn "subprocess.check_output" skipper/` and got two results.

1. `skipper/utils.py:186:    return str(subprocess.check_output(cmd).strip())`
2. `skipper/git.py:19:    return subprocess.check_output(git_command).strip()`

I've fixed #2.
For #1, I'll check if it's actually causing issues or if it's usage is such that it doesn't matter (e.g. just logging).
In `skipper/runner.py`, `run_container_command` is used:
`utils.run_container_command(['network', 'create', net])`
`utils.run_container_command(['network', 'rm', net])`
`result = utils.run_container_command(cmd)`
And `result` is returned:
```python
    result = utils.run_container_command(cmd)
    # ... (some other stuff)
    return result
```
Wait, `runner.run` might be using this. Let's check `skipper/runner.py`.

In `_network_exists`:
`result = utils.run_container_command(cmd)`
`return net in result`
If `result` is `"b'network-name'"`, then `net in result` will still be True. So it might "work" by accident.

But it's still bad practice. Should I fix it? The prompt says "minimal, root-cause source patch". The root cause of the reported issue is in `git.py`.

If I fix `utils.py` as well, it's more thorough. Let's see if I have time/budget.
I've used about 10 tool calls. I have plenty.

Let's fix `skipper/utils.py` as well to be safe, as it's clearly the same pattern.
Wait, `str(subprocess.check_output(cmd).strip())` can be fixed to `subprocess.check_output(cmd).decode('utf-8').strip()`.

Actually, I should check if I should use `.decode('utf-8')` or `universal_newlines=True`.
`universal_newlines=True` is generally preferred in Python 3 for `subprocess`.

Let's look at `skipper/git.py` again.
```python
    return subprocess.check_output(git_command).decode('utf-8').strip()
```
This is fine.

For `skipper/utils.py`:
```python
    return str(subprocess.check_output(cmd).strip())
```
I'll change it to:
```python
    return subprocess.check_output(cmd).decode('utf-8').strip()
```

Wait, if I change `run_container_command` in `utils.py`, I should make sure I don't break anything that expects the `b'...'` string representation. But that's unlikely.

Line 40: `output = check_output("echo " + match, shell=True).strip().decode("utf-8")`
This one is already calling `.decode("utf-8")`. So it's correct.

I'm confident in the fixes.
I'll run one final check to make sure `git.get_hash()` behaves as expected.

Wait, `git.get_hash(short=False)`. What if `short=True`?
```python
def get_hash(short=False):
    # ...
    git_command = ['git', 'rev-parse']
    if short:
        git_command += ['--short']
    git_command += ['HEAD']
    # ...
    return subprocess.check_output(git_command).decode('utf-8').strip()
```
This should also work correctly.

Final check of my changes:
1. `skipper/git.py`: `subprocess.check_output(git_command).strip()` -> `subprocess.check_output(git_command).decode('utf-8').strip()`
2. `skipper/utils.py`: `str(subprocess.check_output(cmd).strip())` -> `subprocess.check_output(cmd).decode('utf-8').strip()`

Both fix the Python 3 `bytes` vs `str` issue when interacting with `subprocess.check_output`.

I'll run `git status --short && git diff` as per protocol.
