On Windows a task file with neither a known extension nor a shebang is skipped — correctly, since
is_executable has no permission bit to consult there — but nothing says so. Measured on
Windows 2026.8.10 against Linux 2026.8.3 as the control:

	Linux (control)	Windows
mise tasks ls	no tasks found, but non-executable files exist … Run chmod +x …	no output at all
mise run <name>, no other tasks	names the file and the directory	no tasks defined in …. Are you in a project directory?
mise run <name>, other tasks present	no task X found, but a non-executable file exists at <path>	that line is absent

Three diagnostics, all excluded on Windows by cfg!(windows).

The exclusion is left-over, and the correct wording already exists

• 2026-03-22, fix(task): improve error message when task files are not executable #8705 added all three. Their text was a hardcoded chmod +x, which is meaningless
  on Windows, so Windows was excluded from the start.
• 2026-08-14, fix(tasks): stop telling Windows users to run chmod +x #11923 ("stop telling Windows users to run chmod +x") added
  file::make_executable_hint — the one place that knows the remedy per platform — and applied it
  in cli/run.rs and cli/tasks/validate.rs.

#11923 was mine and it did not touch cli/tasks/ls.rs or task/task_list.rs. It removed the
reason for the exclusion and left the exclusion. find_non_executable_task_files already works on
Windows (is_executable has a Windows arm), so all that was missing was dropping the gates and
using the wording that is already there.

"not executable" stays as the phrasing: #11923 already settled on it as platform-neutral, and
e2e-win/task.Tests.ps1 pins it. Only the remedy clause changes.

What changed

• cli/tasks/ls.rs — gate dropped; the chmod +x sentence becomes make_executable_hint for
  the first offending file.

• task/task_list.rs, the no-tasks-at-all error — same. One deliberate trade on unix: the
  old text listed up to five files (e.g.:\n chmod +x a b c) and now names one. The count and the
  directories are still reported, and keeping a single owner of the remedy is worth more than the
  list.

• task/task_list.rs, make_task_executable — the function returned early on Windows before
  doing anything. Only the prompt is genuinely inapplicable (make_executable cannot change
  whether Windows runs a file, so a "yes" would be accepted and change nothing), so the early
  return moved below the warning, and on Windows the warning carries the hint instead of handing
  off to a prompt. This matters most: when the project has other tasks, that warning is the only
  thing that names the file.

  Cost: Windows now walks the task directories on a failed task lookup. That is the error path
  only, and the same walk err_no_task already does elsewhere.

Tests

e2e-win/task.Tests.ps1 gets one new Context covering all three sites. The existing
a task file Windows cannot execute context is a different path — a TOML file = task, which
resolves and is then rejected by validate_task (what #11923 fixed). Here nothing resolves at all.

The fixture lives outside $TestDrive on purpose: the config at the TestDrive root includes a
tasks directory, and a project that inherits those tasks never reaches the two diagnostics that
only fire when nothing resolved. MISE_CONFIG_DIR is pointed at an empty directory for the same
reason — this suite does not otherwise isolate global tasks. Each case also asserts
-Not -BeLike '*chmod*', which is the original defect.

The third case runs the working sibling first as a control, so a failure there cannot be mistaken
for an empty project.

No unix e2e was added. e2e/tasks/test_task_non_executable_error and e2e/tasks/test_task_validate
are the regression net; both assert non-executable and chmod +x, which Run: chmod +x <path>
still satisfies, and neither pins the five-file listing.

Verification

The three new cases were run against the released 2026.8.10 binary first and fail for exactly the
reported reasons — empty output, the generic "Are you in a project directory?", and the missing
warning line. The two unix suites were run against the released Linux binary to establish the
before-state; both pass.

cargo fmt --all is clean. cargo check does not run on this machine (libz-ng-sys wants cmake,
not installed), so type-checking and the full e2e-win run are left to CI — nothing here is
reported as having been compiled locally.

📝 Walkthrough

Walkthrough

The change enables Windows diagnostics for non-executable task files. It adds platform-specific executable guidance, preserves non-Windows behavior, and adds isolated Windows end-to-end coverage for task listing and execution.

Changes

Cross-platform task diagnostics

Layer / File(s)	Summary
Cross-platform diagnostic behavior src/cli/tasks/ls.rs, src/task/task_list.rs	Non-executable task detection now runs on Windows. Diagnostics use platform-specific executable hints. Windows reports guidance without prompting or modifying files. Non-Windows prompting remains unchanged. CLI metadata access uses direct command fields.
Windows end-to-end validation e2e-win/task.Tests.ps1	Tests cover empty projects, valid neighboring tasks, mise tasks ls, and mise run. Assertions verify file paths and shebang guidance and exclude chmod instructions.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 8514d

This change improves Windows task-file diagnostics without changing task execution behavior, and no actionable merge-blocking risk remains after normal checks and review.

Suggested reviewers: jdx, risu729

Poem

A rabbit checks the task-file trail,
With Windows hints instead of chmod mail.
Shebangs point the proper way,
Good batch tasks still hop and play.
Tests guard each path today.

Greptile Summary

This PR enables platform-appropriate diagnostics when Windows skips task-directory files that lack a recognized extension or shebang.

• Removes Windows-only diagnostic gates from task listing and failed task lookup paths.
• Uses the shared executable-remediation helper to provide platform-specific guidance.
• Avoids offering Windows users an ineffective executable-permission prompt.
• Adds Windows end-to-end coverage for empty and mixed task directories.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.

Important Files Changed

Filename	Overview
src/cli/tasks/ls.rs	Enables the no-tasks diagnostic on Windows and supplies remediation through the platform-aware executable hint.
src/task/task_list.rs	Enables skipped-file diagnostics on Windows while retaining the executable-marking prompt only on platforms where it is effective.
e2e-win/task.Tests.ps1	Adds isolated Windows coverage for task listing and failed lookup diagnostics with and without runnable sibling tasks.
