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 prompt 5,851 characters

You are evaluating a software engineering task for repository asdf-format/asdf.

Problem Statement:
No longer warn but raise an exception for converters with more than 1 tag that don't implement select tag
To provide backwards compatibility changes were added to:
https://github.com/asdf-format/asdf/pull/1594
where including a converter (that inherits from `Converter`) in an extension which results in the converter having more than 1 tag causes a warning.

For the next major version we should turn this into an error (as mentioned in the warning message).

## 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 objective is to change a warning to an exception for converters that have more than one tag but do not implement the `select` tag.
This was previously introduced as a warning in PR 1594 for backward compatibility.

I need to find where this warning is issued and change it to an exception.

Plan:
1. Search for the warning message related to "more than 1 tag" and "select tag".
2. Identify the location in the code.
3. Determine the appropriate exception to raise.
4. Reproduce the warning using a test case.
5. Implement the change.
6. Verify the exception is raised.

The grep didn't return anything with the exact phrases. Let me try searching for "warning" and "Converter" in the `asdf/extension` directory, as converters are likely defined there. I'll also look for "select" in the codebase.

Okay, I found it in `asdf/extension/_converter.py` at line 197.
The message is `"Converter handles multiple tags for this extension, but does not implement a select_tag method."`.

Let's examine the code around that line.

The task is to turn this warning into an error for the next major version.

Wait, if `Converter in delegate.__class__.__mro__` is true, it warns. Otherwise it raises `RuntimeError`.
The goal is to make it raise an exception in both cases.

What exception should I use? The other branch uses `RuntimeError`. Let me check if there's a more appropriate exception in `asdf/exceptions.py`.

There's no specific exception for this, so `RuntimeError` seems acceptable, as it's already used in the other branch.

Let's double check if there is any other place where this might be relevant.

I'll create a reproduction script to see the warning in action.

I need to know how `Converter` and extensions work to set up the test.
`asdf/extension/_converter.py` seems to be the place where the logic is.
I'll look at `asdf/_tests/test_block_converter.py` or `asdf/_tests/test_extension.py` for ideas on how to trigger this.

The test is parameterized (I assume, because of `is_subclass` and `indirect` variables which must be coming from `@pytest.mark.parametrize`).

```python
    ParentClass = Converter if is_subclass else object
    # ...
    class FooConverter(ParentClass):
        tags = ["asdf://somewhere.org/tags/foo-*"]
        # ...
    tags = [
        "asdf://somewhere.org/tags/foo-1.0.0",
        "asdf://somewhere.org/tags/foo-2.0.0",
    ]
    extension = FullExtension(converters=[FooConverter()], tags=tags)
    ctx_type = pytest.warns if is_subclass else pytest.raises
    exception_class = AsdfWarning if is_subclass else RuntimeError
    with config_context() as config:
        with ctx_type(exception_class, match="Converter handles multiple tags"):
            config.add_extension(extension)
```

If `is_subclass` is true, it expects `AsdfWarning`. If false, it expects `RuntimeError`.

To reproduce the issue, I can just run this test (or a similar one) and see if it passes (meaning it warns).

Let's find the full test function to see the parametrization.

The file `asdf/_version.py` is missing. I should check how versioning is handled.
Looking at `asdf/versioning.py`.

Wait, if I just want to test the `ConverterProxy` logic, I might be able to run a small script without importing the full `asdf` package if possible, or I can try to mock `asdf._version`.

Actually, if the package is installed in the environment, `import asdf` should work. But the `pytest` is trying to load from `/workspace/asdf`.

The tests passed! This means that for `is_subclass=True`, it currently warns, and for `is_subclass=False`, it raises `RuntimeError`. This confirms the current behavior.

Now I will implement the change: replace the `warnings.warn(msg, AsdfWarning)` with `raise RuntimeError(msg)`.

Wait, looking at the code again:

```python
if len(relevant_tags) > 1 and not hasattr(delegate, "select_tag"):
# we cannot use isinstance here because Converter supports
# virtual subclasses
if Converter in delegate.__class__.__mro__:\n # prior to asdf 3.0 Converter provided a default select_tag
# to provide backwards compatibility allow Converter subclasses
# to be registered with >1 tag but produce a warning
msg = (
"Converter handles multiple tags for this extension, "
"but does not implement a select_tag method. "
"This previously worked because Converter subclasses inherited "
"the now removed select_tag. This will be an error in a future "
"version of asdf"
)
warnings.warn(msg, AsdfWarning)
else:
msg = "Converter handles multiple tags for this extension, but does not implement a select_tag method."
raise RuntimeError(msg)
```

I should probably simplify this. If `len(relevant_tags) > 1 and not hasattr(delegate, "select_tag")`, it should always raise an error.

Wait, if I just change `warnings.warn(msg, AsdfWarning)` to `raise RuntimeError(msg)`, I'll have two branches doing almost the same thing with slightly different messages.

Let's see:
Branch 1 (subclass): "Converter handles multiple tags for this extension, but does not implement a select_tag method. This previously worked because Converter subclasses inherited the now removed select_tag. This will be an error in a future version of asdf"
Branch 2 (not subclass): "Converter handles multiple tags for this extension, but does not implement a select_tag method."

If I'm turning it into an error, maybe I should keep the more detailed message for subclasses to help them migrate? Or just unify them.

The problem statement says: "No longer warn but raise an exception for converters with more than 1 tag that don't implement select tag".

Let's see if I can just unify it to a single `RuntimeError`.

```python
if len(relevant_tags) > 1 and not hasattr(delegate, "select_tag"):
msg = "Converter handles multiple tags for this extension, but does not implement a select_tag method."
raise RuntimeError(msg)
```

However, the existing code differentiates between those that inherit from `Converter` and those that don't.

If I want to be surgical, I can just change the `warnings.warn` to `raise RuntimeError`.

```python
if Converter in delegate.__class__.__mro__:
# ...
msg = (
"Converter handles multiple tags for this extension, "
"but does not implement a select_tag method. "
# ...
)
raise RuntimeError(msg)
else:
msg = "Converter handles multiple tags for this extension, but does not implement a select_tag method."
raise RuntimeError(msg)
```

Actually, the most concise way is:

But wait, if the user's converter inherits from `Converter`, they might appreciate the explanation of *why* this was changed.

Let's look at the original code again.

```python
if len(relevant_tags) > 1 and not hasattr(delegate, "select_tag"):
# we cannot use isinstance here because Converter supports
# virtual subclasses
if Converter in delegate.__class__.__mro__:
# prior to asdf 3.0 Converter provided a default select_tag
# to provide backwards compatibility allow Converter subclasses
# to be registered with >1 tag but produce a warning
msg = (
"Converter handles multiple tags for this extension, "
"but does not implement a select_tag method. "
"This previously worked because Converter subclasses inherited "
"the now removed select_tag. This will be an error in a future "
"version of asdf"
)
warnings.warn(msg, AsdfWarning)
else:
msg = "Converter handles multiple tags for this extension, but does not implement a select_tag method."
raise RuntimeError(msg)
```

If I change `warnings.warn(msg, AsdfWarning)` to `raise RuntimeError(msg)`, it's done.

Now let's check if I should also update the test case `test_warning_or_error_for_default_select_tag` in `asdf/_tests/test_extension.py` to expect an exception in both cases.

Wait, the rules say: "Before running official verification, the grading harness strips and reverts all changes to tests/...". So I should NOT change the tests in `/workspace/asdf/_tests/` if I want them to be reverted. But I MUST make sure the code passes the existing tests (which might be updated in the grading harness).

Wait, if the existing test expects a warning when `is_subclass` is True, and I change the code to raise an exception, the test will FAIL.

The test is:
```python
ctx_type = pytest.warns if is_subclass else pytest.raises
exception_class = AsdfWarning if is_subclass else RuntimeError
with config_context() as config:
with ctx_type(exception_class, match="Converter handles multiple tags"):
config.add_extension(extension)
```

If I change the code to raise `RuntimeError` for both, then when `is_subclass` is True, `ctx_type` is `pytest.warns` and `exception_class` is `AsdfWarning`. But the code will raise `RuntimeError`, so `pytest.warns(AsdfWarning)` will fail because an exception was raised instead of a warning.

So I SHOULD update the test to reflect the new requirements if I want to verify my fix locally. Even if the grader reverts it, I need to see it passing (or failing correctly) to be sure.

Wait, the rule says "Every part of your fix MUST reside in non-test production source files."
If the grading harness reverts my changes to tests, then the tests used for grading will be the original ones. If the original tests expect a warning and I raise an error, I will fail the tests unless the grading harness also updates the tests.

Usually, in these tasks, the tests are updated by the grader or I am expected to find the tests and update them, but the "Protected Grading Paths" rule says "The grading harness strips and reverts all changes to tests/...".

This is confusing. If I change the code to raise an exception, and the test expects a warning, the test will fail. If the grader reverts my test changes, it will still fail.

Does this mean the tests are also updated in the grader's environment, but I shouldn't touch them in *my* submission? Yes, probably.

Let me double check the "Protected Grading Paths" rule.
"Before running official verification, the grading harness strips and reverts all changes to tests/... Every part of your fix MUST reside in non-test production source files."

This means I can't submit changes to tests. But if the current tests fail because I changed the behavior from warning to error, how can it pass?

Answer: The tests that are part of the official grading suite (which might be different from the ones in the repo) will already be updated to expect the error. Or the tests in the repo *are* the grading tests, but they will be updated by the grader.

Wait, if I run the tests now, and they pass, then they are expecting the current behavior (warning). If I change the behavior to raise an exception, they will fail.

Let's try to implement the change and see.

I will:
1. Change `warnings.warn(msg, AsdfWarning)` to `raise RuntimeError(msg)` in `asdf/extension/_converter.py`.
2. Run the tests and see them fail.
3. This confirms the change is working as expected (it's no longer warning, it's raising).

Wait, I can also just check if I should use a different exception than `RuntimeError`. The original code uses `RuntimeError` for non-subclasses.

Let's refine the code in `asdf/extension/_converter.py`.

```python
if len(relevant_tags) > 1 and not hasattr(delegate, "select_tag"):
# we cannot use isinstance here because Converter supports
# virtual subclasses
if Converter in delegate.__class__.__mro__:
# prior to asdf 3.0 Converter provided a default select_tag
# to provide backwards compatibility allow Converter subclasses
# to be registered with >1 tag but produce a warning
msg = (
"Converter handles multiple tags for this extension, "
"but does not implement a select_tag method. "
"This previously worked because Converter subclasses inherited "
"the now removed select_tag. This will be an error in a future "
"version of asdf"
)
raise RuntimeError(msg)
else:
msg = "Converter handles multiple tags for this extension, but does not implement a select_tag method."
raise RuntimeError(msg)
```

Actually, I can simplify this to:

```python
if len(relevant_tags) > 1 and not hasattr(delegate, "select_tag"):
# we cannot use isinstance here because Converter supports
# virtual subclasses
if Converter in delegate.__class__.__mro__:
msg = (
"Converter handles multiple tags for this extension, "
"but does not implement a select_tag method. "
"This previously worked because Converter subclasses inherited "
"the now removed select_tag. This will be an error in a future "
"version of asdf"
)
else:
msg = "Converter handles multiple tags for this extension, but does not implement a select_tag method."
raise RuntimeError(msg)
```

This is cleaner.

Let's try to apply this.

Wait, I should also check if I should be using `AsdfSerializationError` or something else. But the other branch uses `RuntimeError`.

Let's check the problem statement again. "No longer warn but raise an exception". It doesn't specify which exception.

I'll use `RuntimeError` as it is already used.

Applying the change.

The `asdf-format/asdf` repository was updated to consistently raise a `RuntimeError` when a converter handles multiple tags but does not implement the `select_tag` method. The previous behavior of issuing an `AsdfWarning` for `Converter` subclasses has been removed to ensure uniform error handling across all converter implementations.

The objective is to change a warning to an exception for converters that have more than one tag but do not implement the `select` tag.
This was previously introduced as a warning in PR 1594 for backward compatibility.

I need to find where this warning is issued and change it to an exception.

Plan:
1. Search for the warning message related to "more than 1 tag" and "select tag".
2. Identify the location in the code.
3. Determine the appropriate exception to raise.
4. Reproduce the warning using a test case.
5. Implement the change.
6. Verify the exception is raised.

There's no specific exception for this, so `RuntimeError` seems acceptable, as it's already used in the other branch.

Let's double check if there is any other place where this might be relevant.

I'll create a reproduction script to see the warning in action.

The test is parameterized (I assume, because of `is_subclass` and `indirect` variables which must be coming from `@pytest.mark.parametrize`).

```python
    ParentClass = Converter if is_subclass else object
    # ...
    class FooConverter(ParentClass):
        tags = ["asdf://somewhere.org/tags/foo-*"]
        # ...
    tags = [

    extension = FullExtension(converters=[FooConverter()], tags=tags)
    ctx_type = pytest.warns if is_subclass else pytest.raises

    with config_context() as config:
        with ctx_type(exception_class, match="Converter handles multiple tags"):
            config.add_extension(extension)
```

If `is_subclass` is true, it expects `AsdfWarning`. If false, it expects `RuntimeError`.

To reproduce the issue, I can just run this test (or a similar one) and see if it passes (meaning it warns).
