Problem

isPathWord only looked for /, so a Windows-style path such as /foo\bar or /Windows\System32 still opened the slash-command picker.

Change

Treat \ like / when deciding the token is a path.

Scope and approval

Obvious composer trigger boundary bug; same intent as the existing forward-slash path guard.

Verification

• Added cases for cmd /foo\bar and /Windows\System32.
• vp test run packages/shared/src/composerTrigger.test.ts — 27 passed.

Attribution

Written by grok-4.5 in T3 Code (Grok harness).

Fixes #27852

Walkthrough

isPathWord now recognizes / and \ as path separators. Two tests verify that backslash-containing paths do not trigger the slash menu.

Changes: Path separator detection

Layer / File(s)	Summary
Path check and test coverage packages/shared/src/composerTrigger.ts, packages/shared/src/composerTrigger.test.ts	isPathWord checks for / or \ after the first character. Tests cover a slash-prefixed path containing a backslash and a Windows-style absolute path.

Change: Bug fix · Severity of issue fixed: Low

Suggested reviewers: juliusmarminge, macroscopeapp

Merge Risk: Minimal · up to 333dc

Windows-style paths such as cmd /foo\bar no longer open the slash-command picker. The change is small and localized, with tests, and no merge-blocking risk is evident.

Full details: Title check

Explanation

The title names the fix: Windows-style paths no longer open the slash menu. The change makes isPathWord treat backslash like forward slash, and the tests cover both Windows-style path cases. The title matches the main change and uses the conventional commit format.

Full details: Description check

Explanation

The description follows the template. It states the problem, the change, the scope with a reason for no separate issue, and verification with a test command and result. It links the issue (#27852). The Attribution section adds the model and harness, as the template asks. The Verification section lists only one focused test run and gives no manual check, but the template accepts focused tests. The description is mostly complete.

Full details: Linked Issues check

Explanation

Issue #27852 requires that Windows-style paths such as cmd /foo\bar and /Windows\System32 not open the slash-command menu. At the reviewed head, isPathWord in packages/shared/src/composerTrigger.ts now returns true when the word after its first character contains / or \ (/[/\\]/). In detectComposerTrigger, both the line-start / branch and the token / branch return null when isPathWord is true. Tracing cmd /foo\bar (token /foo\bar) and /Windows\System32 (line prefix matches ^\/(\S*)$) confirms both return null. The same path, with forward slashes, already returns null, so the expected behavior matches /tmp/build.sh. The test file adds both cases to the existing keeps the path ... out of the slash menu table. The issue is coding-only and its scope is packages/shared, which the change covers.

Full details: Out of Scope Changes check

Explanation

The whole-PR diff against the merge base changes two files. packages/shared/src/composerTrigger.ts changes the isPathWord predicate from a /-only check to a / or \ check and updates its doc comment to match. packages/shared/src/composerTrigger.test.ts adds two test cases for the reported inputs. Both changes fall within the scope of issue #27852 and the PR description. No unrelated code, refactoring, or other packages are modified. The isPathWord change also affects the existing line-start and token path checks, which is the intended behavior for the same bug.

Add a cursor-before-backslash regression case.

The path tests only place the cursor at the token end for backslash paths. Add a case with the cursor after /foo in cmd /foo\bar. This protects the changed isPathWord behavior that suppresses the slash menu before a later backslash.

Evidence

In a thread composer, type /Windows\System32 with the caret at the end; clear it and type cmd /foo\bar; clear it and type /tmp/build.sh as the control.

Both sides: real web app in Chromium on Linux, 1280×800 CSS viewport, light theme, fresh databases seeded by the same synthetic replay-thread script. Both backslash inputs open “No matching command.” on base and remain ordinary text on head. The forward-slash control keeps the drawer closed on both.

Manual evidence supplies the verdict: two scenario attempts exited 2 due to locator errors. Every final still passed a pixel-identical frame comparison at least 500 ms apart; the blinking caret was hidden for capture. All captures were visually inspected.
