fix(scripts): pin the streams to UTF-8 in the remaining skill scripts#2826aranellaeth wants to merge 4 commits into
Conversation
Three installed skill scripts still resolve their console encoding from the
platform default. On Windows that is cp1252, so a project whose research,
headings or paths carry a character outside it either loses the text or takes
the script down. Measured on Windows 11 against v6.12.0, no environment
overrides: cp1252 is simply what sys.stdout.encoding already is there.
recon_kit.py pins nothing at all, and every subcommand prints JSON with
ensure_ascii=False. `escape-sources` emits the source appendix, where a
non-English title is ordinary, and dies outright:
UnicodeEncodeError: 'charmap' codec can't encode character 'ş'
Reading the report from "-" has the mirror defect: stdin decodes as cp1252
too, so a UTF-8 report arrives as Türkiye Bilişim Derneği and the mojibake
is written into the briefing without any error at all. All three streams are
pinned now.
word_metrics.py and pick_methods.py pin stdout but not stderr, which is where
both quote the caller's path. The filename the user needs in order to fix the
call comes back escaped:
error: not a readable file: ...\belge-şık.md
error: could not read --extra: ...\ek-şık.json
Generalizes the pin_utf8 helper merged for brain.py in bmad-code-org#2578 to all three,
replacing the inline reconfigure in the latter two. errors= is passed through
so stderr's backslashreplace default is not silently downgraded to strict.
Adds four tests. The two stderr cases and the escape-sources case drive a
subprocess under PYTHONIOENCODING=cp1252. The stdin case runs in-process on
purpose: PYTHONIOENCODING sets every stream to the same code page, and
decoding UTF-8 as cp1252 then encoding it back is an exact round trip, so a
subprocess would cancel the corruption out and pass unpinned. Each was
verified to fail with its own pin removed.
recon_kit 6 -> 8 tests, word_metrics 5 -> 6, pick_methods 22 -> 23; all green.

Greptile SummaryPins standard streams to UTF-8 while preserving each stream’s error handler, preventing Unicode corruption and encoding failures on locale-dependent platforms.
Confidence Score: 5/5The PR appears safe to merge, with no concrete blocking or independently actionable non-blocking issues identified. The guarded stream configuration preserves existing error handlers, supports the stream wrappers used by current callers, and the added tests exercise the intended Windows encoding failure paths.

Fills the docstring coverage gap the review flagged, over the functions and test entities in the diff and their immediate neighbours: fmt_rows and metrics, which sit directly above the new pin_utf8 in their files, the escape-source cases around the new recon_kit tests, and the word-metric suite, which is small enough to finish rather than leave half documented. Coverage over the touched set goes from 68.75% to 100%, counting the changed hunks alone or with three lines of context either side. Pure additions, no behavior change; recon_kit 8, word_metrics 6, pick_methods 23, all passing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

One more skill script with the same gap. sprint_status speaks JSON on stdout
with the default ensure_ascii, so that side was already safe, but _restore
writes the one plain-text diagnostic this script emits:
sys.stderr.write(f"restore failed: {exc}\n")
The OSError it quotes carries the target path, so on a Windows console
(cp1252) the file the user needs to go look at comes back as escapes, at the
exact moment they have been told a write may have been left half finished.
Pins both streams at main() entry with the same helper as its siblings.
Testing it took two steps, because _restore cannot be reached through the CLI
-- the suite's own _module() helper exists for that reason. So one test drives
main() with a cp1252 stderr and asserts the stream comes back UTF-8 with its
error handler intact, and a second drives _restore directly, pinned the way
main() pins it, and asserts a path containing Turkish characters is readable
in the bytes rather than escaped. Two more cover the helper itself, matching
the pair merged for brain.py in bmad-code-org#2578. Each fails with its own line reverted.
sprint_status goes 87 -> 91 passing. The 4 failures that remain on Windows are
present on a clean checkout of main too and are untouched here: they assert
POSIX semantics (chmod on a directory, symlink creation, st_mode round-trip)
that Windows does not provide. Worth a separate look, not this PR's business.
Also documents build_parser and the new test entities, keeping the touched set
at 100%.

Move the direct pytest runner to the end of the file.
When the file runs directly, pytest.main() executes before the four new test functions are defined. That invocation does not collect the new UTF-8 regression tests, so it can pass without exercising them. Move the if __name__ == "__main__": block below the final test.

The four new cases were appended past `if __name__ == "__main__"`, which put them below the file's entry point. Collection is unaffected -- the guard calls pytest.main([__file__]), and that import binds the module under its own name, so every definition below the guard is still created and collected -- but a file whose entry point sits in the middle reads as a mistake and would become one the moment the guard stopped re-entering pytest with an explicit path. Moves the guard back to the end. 95 collected before and after; the suite is unchanged at 91 passing with the 4 pre-existing Windows failures. Also documents test_post_write_status_mismatch_restores, which the reorder pulls into the docstring-coverage scope. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Moved it in The stated cause does not hold, though, and it is worth being exact since it changes whether this was a coverage gap or a tidiness one. The guard is 95 collected and 91 passing both before and after the move — 87 passing on a clean checkout of Worth fixing regardless: a file whose entry point sits in the middle reads as a mistake, and it would become one the moment that guard stopped re-entering pytest with an explicit path.
