System instructions 4,822 characters
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.

## Task Budget (Session terminates when any budget is exhausted)
- Time allowance: 7.5 minutes
- Tool calls allowance: 30 calls
- Max loop iterations: 40 turns

## Execution Environment Rules
- Single command timeout: 90 seconds (commands exceeding this fail without ending the session)
- Command output limit: 5000 characters
- File view limit: 150 lines per read_file call
- File character limit: 10000 characters per read_file call
- Environment is offline (no network/PyPI access). All repository and test dependencies are ALREADY pre-installed. Do NOT attempt to run pip install or download packages.

## Instructions:
0. All source code is under `/workspace`. Do NOT search outside `/workspace` (e.g. `/usr/`, `/wheels/`, system site-packages). If imports fail, the issue is in the source code under `/workspace`, not in missing system packages.
1. Analyze the problem statement and any provided hints carefully to identify all requested script paths, CLI subcommands, or Python modules.
2. Inspect existing codebase conventions and test files before making edits.
3. Verify your implementation using targeted tests or inline assertions before submitting.
4. Call submit_patch only after your implementation is complete and verified.
5. As your final action, you must return a text-only response reporting your completion to terminate the session.

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: `fqdn_image = image + ':' + tag`.

This implies 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.

Line 117 is `fqdn_image = image + ':' + tag`.
`tag` is defined on line 107: `tag = git.get_hash()`.
`image` comes from `valid_images_to_build` which is derived from `valid_images`.

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

In `skipper/git.py`, `get_hash()` returns `subprocess.check_output(git_command).strip()`.
`subprocess.check_output` returns `bytes` in Python 3.
Since the traceback shows Python 3.9, `tag` will be of type `bytes`.
On the other hand, `image` is likely a `str` (coming from some config).
So `image + ':' + tag` fails because we are trying to concatenate `str` and `bytes`.

To fix this, we should ensure `get_hash()` returns a `str`.
The easiest way is to add `encoding='utf-8'` or `universal_newlines=True` to `subprocess.check_output`, or decode the result.

Let's see if there are other places where `get_hash` is used.

Yes, `get_hash()` is used in several places in `skipper/cli.py`.

Let's try to reproduce this failure. I'll write a small script that calls `get_hash()` and tries to concatenate it with a string.
I need to be in a git repository for `get_hash` to work. `/workspace` is likely a git repository.

Reproduction successful. `get_hash()` returns `bytes`.

I will now fix `skipper/git.py` to ensure `get_hash()` returns a `str`.
I'll use `.decode('utf-8')` on the result of `subprocess.check_output(git_command).strip()`.

Wait, `subprocess.check_output(git_command).strip()` returns `bytes`. If I call `.strip()` on `bytes`, it returns `bytes`.
If I do `subprocess.check_output(git_command).decode('utf-8').strip()`, it will return `str`.

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

```python
def get_hash(short=False):
    if not os.path.exists('.git'):
        logging.warning('*** Not working in a git repository ***')
        return 'none'

    git_command = ['git', 'rev-parse']
    if short:
        git_command += ['--short']
    git_command += ['HEAD']

    if uncommitted_changes():
        logging.warning("*** Uncommitted changes present - Build container version might be outdated ***")

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

Wait, `AttributeError: 'str' object has no attribute 'decode'`.
This means `subprocess.check_output(git_command)` is ALREADY returning a `str` in the test environment.

Why? Let's look at `tests/test_git.py`.

Ah, the tests are mocking `subprocess.check_output` to return a `str`:
`@mock.patch('subprocess.check_output', return_value=GIT_HASH_FULL)` where `GIT_HASH_FULL = '00efe974e3cf18c3493f110f5aeda04ff78b125f'`.

So in the real world, it returns `bytes`, but in the tests, it returns `str`.

The `AttributeError: 'str' object has no attribute 'decode'` confirms that in the tests, `subprocess.check_output(git_command)` is a `str`.

To handle both, I can check if the result is `bytes` before decoding, or just use `text=True` (or `universal_newlines=True`) in `subprocess.check_output` which is the modern way to get a `str` return value in Python 3.

Wait, `subprocess.check_output` has `universal_newlines` (which is an alias for `text` since Python 3.7).

If I use `subprocess.check_output(git_command, universal_newlines=True).strip()`, it should return a `str` regardless of whether it's a real call or a mock (assuming the mock is returning a `str` as it does now).

Let's check how `subprocess.check_output(..., universal_newlines=True)` behaves with the mock.
If the mock is `lambda *args, **kwargs: 'some_string'`, then `subprocess.check_output(git_command, universal_newlines=True)` will return `'some_string'`.

Let's try this change.

The tests are failing because they expect `subprocess.check_output` to be called with only one argument (the command list), but I added `universal_newlines=True`.

According to the rules: "Protected Grading Paths: Before running official verification, the grading harness strips and reverts all changes to tests/".
So I CANNOT modify the tests to match my fix.

I must find a way to fix the bug in the production code without changing the arguments passed to `subprocess.check_output` in a way that breaks the tests.

If I can't use `universal_newlines=True`, I must go back to decoding the result. But I need to handle the case where it's already a `str` (to satisfy the tests) and where it's `bytes` (to satisfy the real world).

Wait, `subprocess.check_output` always returns `bytes` in Python 3 if `universal_newlines` is False. The tests are mocking it to return `str`.

So in the implementation, I can do:
```python
res = subprocess.check_output(git_command)
if isinstance(res, bytes):
    res = res.decode('utf-8')
return res.strip()
```

Let's try this.

Wait, `uncommitted_changes` also uses `subprocess.call`. This one returns an int, so it's fine.

I noticed that `get_hash` is the only function using `check_output`.

One more thing: in Python 3, `subprocess.check_output` returns `bytes` unless `universal_newlines` (or `text` in 3.7+) is True.
Since the tests mock it to return a string, my `isinstance(res, bytes)` check handles both.

Let's verify if there are any other uses of `check_output` in the repository.

I should check `./skipper/utils.py:186:    return str(subprocess.check_output(cmd).strip())` and `./skipper/config.py:39:        output = check_output("echo " + match, shell=True).strip().decode("utf-8")`.

In `skipper/config.py:39`, it already has `.decode("utf-8")`.
In `skipper/utils.py:186`, it has `str(subprocess.check_output(cmd).strip())`. If `check_output` returns `bytes`, `str(b'foo')` will be `"b'foo'"` which is probably not what is intended. It should be `b'foo'.decode('utf-8')` or similar.

Wait, I should focus on the reported issue. The issue was specifically about `skipper build` and `get_hash`.

`run_container_command(args)` uses `str(subprocess.check_output(cmd).strip())`.
In Python 3, if `subprocess.check_output(cmd)` returns `bytes`, `.strip()` will return `bytes`, and `str(bytes)` will return the representation of the bytes (e.g., `"b'result'"`).

This looks like another potential bug, but is it related to the current issue? The issue was about `TypeError: can only concatenate str (not "bytes") to str`. `str(bytes)` returns a string, so it wouldn't cause a `TypeError` on concatenation, but it would result in the wrong string value.

However, the user only reported the `TypeError` in `skipper/cli.py` caused by `get_hash`.

I'll stick to fixing `get_hash` for now, as that was the requested fix. If I start fixing other things, I might introduce new bugs or fail other tests.

Let's double check `get_status` and `git status --short && git diff`.

Wait, the diff shows:
`-    return subprocess.check_output(git_command).strip()`
`+    res = subprocess.check_output(git_command)`
`+    if isinstance(res, bytes):`
`+        res = res.decode('utf-8')`
`+    return res.strip()`

This means the original code was `return subprocess.check_output(git_command).strip()`. I had previously changed it to use `universal_newlines=True` and then changed it back to this.

Actually, the diff I just saw is against the ORIGINAL base commit, and I have my changes.

Wait, if the original code was `return subprocess.check_output(git_command).strip()`, then `get_hash()` returns `bytes`.
Then in `skipper/cli.py`:
`fqdn_image = image + ':' + tag`
Since `tag` is `bytes`, this causes the `TypeError`.

My fix:
```python
    res = subprocess.check_output(git_command)
    if isinstance(res, bytes):
        res = res.decode('utf-8')
    return res.strip()
```
This ensures `get_hash()` returns a string.

And it doesn't break the tests because if the mock returns a string, `isinstance(res, bytes)` is False and it just calls `.strip()` on the string.

One detail: `tag = git.get_hash()` is called in `cli.py`.

Let's confirm that this is indeed the only place where we need this fix.

I'll do one final check of the reproduction and tests.

The issue was caused by `subprocess.check_output` returning `bytes` in Python 3, which led to a `TypeError` when concatenating the resulting git hash (tag) with a string in `skipper/cli.py`. I resolved this by updating `skipper/git.py` to check if the output is `bytes` and decode it to a UTF-8 string before returning, ensuring compatibility with both the real-world environment and existing test mocks.

`subprocess.check_output` returns `bytes` in Python 3.
Since the traceback shows Python 3.9, `tag` will be of type `bytes`.

    if not os.path.exists('.git'):
        logging.warning('*** Not working in a git repository ***')
        return 'none'

    git_command = ['git', 'rev-parse']
    if short:
        git_command += ['--short']
    git_command += ['HEAD']

    if uncommitted_changes():
        logging.warning("*** Uncommitted changes present - Build container version might be outdated ***")

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

The fix is straightforward.
Reproduction successful. `get_hash()` returns `bytes`. I will now fix `skipper/git.py` to ensure `get_hash()` returns a `str`. I'll use `.decode('utf-8')` on the result of `subprocess.check_output(git_command).strip()`. Wait, `subprocess.check_output(git_command).strip()` returns `bytes`. If I call `.strip()` on `bytes`, it returns `bytes`. If I do `subprocess.check_output(git_command).decode('utf-8').strip()`, it will return `str`. Let's check `skipper/git.py` again. ```python def get_hash(short=False): if not os.path.exists('.git'): logging.warning('*** Not working in a git repository ***') return 'none' git_command = ['git', 'rev-parse'] if short: git_command += ['--short'] git_command += ['HEAD'] if uncommitted_changes(): logging.warning("*** Uncommitted changes present - Build container version might be outdated ***") return subprocess.check_output(git_command).strip() ``` The fix is straightforward. <channel|><|tool_call>call:edit_file{filepath:<|"|>skipper/git.py<|"|>,new_string:<|"|> return subprocess.check_output(git_command).decode('utf-8').strip()<|"|>,old_string:<|"|> return subprocess.check_output(git_command).strip()<|"|>}<tool_call|><|tool_response>

Ah, the tests are mocking `subprocess.check_output` to return a `str`:
`@mock.patch('subprocess.check_output', return_value=GIT_HASH_FULL)` where `GIT_HASH_FULL = '00efe974e3cf18c3493f110f5aeda04ff78b125f'`.

So in the real world, it returns `bytes`, but in the tests, it returns `str`.

The `AttributeError: 'str' object has no attribute 'decode'` confirms that in the tests, `subprocess.check_output(git_command)` is a `str`.

To handle both, I can check if the result is `bytes` before decoding, or just use `text=True` (or `universal_newlines=True`) in `subprocess.check_output` which is the modern way to get a `str` return value in Python 3.

Wait, `subprocess.check_output` has `universal_newlines` (which is an alias for `text` since Python 3.7).

If I use `subprocess.check_output(git_command, universal_newlines=True).strip()`, it should return a `str` regardless of whether it's a real call or a mock (assuming the mock is returning a `str` as it does now).

Let's check how `subprocess.check_output(..., universal_newlines=True)` behaves with the mock.
If the mock is `lambda *args, **kwargs: 'some_string'`, then `subprocess.check_output(git_command, universal_newlines=True)` will return `'some_string'`.

Let's try this change.

The tests are failing because they expect `subprocess.check_output` to be called with only one argument (the command list), but I added `universal_newlines=True`.

According to the rules: "Protected Grading Paths: Before running official verification, the grading harness strips and reverts all changes to tests/".
So I CANNOT modify the tests to match my fix.

I must find a way to fix the bug in the production code without changing the arguments passed to `subprocess.check_output` in a way that breaks the tests.

If I can't use `universal_newlines=True`, I must go back to decoding the result. But I need to handle the case where it's already a `str` (to satisfy the tests) and where it's `bytes` (to satisfy the real world).

Wait, `subprocess.check_output` always returns `bytes` in Python 3 if `universal_newlines` is False. The tests are mocking it to return `str`.

`run_container_command(args)` uses `str(subprocess.check_output(cmd).strip())`.
In Python 3, if `subprocess.check_output(cmd)` returns `bytes`, `.strip()` will return `bytes`, and `str(bytes)` will return the representation of the bytes (e.g., `"b'result'"`).

This looks like another potential bug, but is it related to the current issue? The issue was about `TypeError: can only concatenate str (not "bytes") to str`. `str(bytes)` returns a string, so it wouldn't cause a `TypeError` on concatenation, but it would result in the wrong string value.

However, the user only reported the `TypeError` in `skipper/cli.py` caused by `get_hash`.

I'll stick to fixing `get_hash` for now, as that was the requested fix. If I start fixing other things, I might introduce new bugs or fail other tests.

Wait, the diff shows:
`-    return subprocess.check_output(git_command).strip()`
`+    res = subprocess.check_output(git_command)`
`+    if isinstance(res, bytes):`
`+        res = res.decode('utf-8')`
`+    return res.strip()`

This means the original code was `return subprocess.check_output(git_command).strip()`. I had previously changed it to use `universal_newlines=True` and then changed it back to this.

Actually, the diff I just saw is against the ORIGINAL base commit, and I have my changes.

Wait, if the original code was `return subprocess.check_output(git_command).strip()`, then `get_hash()` returns `bytes`.
Then in `skipper/cli.py`:
`fqdn_image = image + ':' + tag`
Since `tag` is `bytes`, this causes the `TypeError`.

My fix:
```python
    res = subprocess.check_output(git_command)
    if isinstance(res, bytes):
        res = res.decode('utf-8')
    return res.strip()
```
This ensures `get_hash()` returns a string.

And it doesn't break the tests because if the mock returns a string, `isinstance(res, bytes)` is False and it just calls `.strip()` on the string.

One detail: `tag = git.get_hash()` is called in `cli.py`.

Let's confirm that this is indeed the only place where we need this fix.

I'll do one final check of the reproduction and tests.
