fix(sanitizer): match attribute quotes by type to avoid mangling content by bymle · Pull Request #1371 · anthropics/claude-code-action (original) (raw)

stripHiddenAttributes used the pattern ["'][^"']*["'] for each quoted attribute, which matches an opening quote of either type and stops at the first quote of either type. When a value contained the other quote character — e.g. an apostrophe inside a double-quoted attribute like title="We'll do it" — the match terminated at the apostrophe, so the wrong span was removed and the surrounding text was corrupted (e.g. <Tooltip title="We'll do it" placement="top"> became <Tooltipll do it" placement="top">).

This surfaced via the github_inline_comment MCP tool: suggestion blocks whose code lines contain quotes were mangled before posting (anthropics#1366).

Match each quoted form per quote type ("[^"]*" and '[^']*'), mirroring stripMarkdownLinkTitles, so a value may freely contain the other quote character. The unquoted fallback is unchanged.

Closes anthropics#1366
