ReleasePort's take

Light signal

editorial:auto 14d

v0.6.1 adds optional `document_handle` parameter to all 45+ tools, enabling parallel agents to edit different documents without clobbering state. Empty handles default to `__default__` for backward compatibility.

Why it matters: Concurrent document editing now available across all 45+ tools; empty handles maintain backward compatibility. Test multi-agent workflows in dev before production use.

Full changelog

What's new

Concurrent session support (contributed by @FeritMelih)

All 45+ tools now accept an optional document_handle string parameter. Multiple clients (e.g. parallel agents in a single Claude Code session) can edit different documents through one server process without clobbering each other's state.

Usage:

Single-client callers: omit the handle — identical behavior to before
Parallel-aware callers: pass a unique handle (e.g. a UUID) per session

# Parallel agents — each gets its own isolated slot
h1 = json.loads(open_document("/path/to/a.docx", document_handle="session-1"))["handle"]
h2 = json.loads(open_document("/path/to/b.docx", document_handle="session-2"))["handle"]

search_text("clause", document_handle=h1)  # sees only a.docx
search_text("clause", document_handle=h2)  # sees only b.docx

open_document, create_document, and create_from_markdown now return the handle in their response so callers can capture and thread it through subsequent calls.

Backward compatible: empty handle resolves to __default__ slot — no existing code needs to change.
