# (snippets use relative paths that resolve when inlined; /oss/langchain/agents uses redirect)
# Excluded: /langsmith/agent-server-api/, /api-reference/ (Mintlify-generated at deploy, not in local build)
# Excluded: ../langchain/agents, ../langgraph/local-server (snippet preprocessing: /oss/... → relative path, resolves when inlined)
# python3 normalizes U+00A0 (NBSP) to space so grep works on both macOS and Linux ([[:space:]] treats NBSP differently by locale)
# Failure: only when filtered output still has indented link lines (real broken links we care about)
# Run mint, capture output, filter exclusions. Only show output when failing.
