How v1.5.0 made co-authoring possible.", "summary": "Loomcycle v1.5.0 enables co-authoring between agents and humans by introducing user-scoped MCP dispatch, config-declared static principals, and deep-merge configuration. The update allows agents and humans to edit different chunks of a document concurrently under optimistic-revision concurrency, with Channel events firing on every chunk update.", "body_md": "loomcycle v1.5.0 ships three changes that compose into a workflow. RFC AG keys the /v1/_mcp dispatch off the authenticated principal, so user-scoped Memory, Documents, and Path under the MCP-server transport now share the same per-scope SQLite file as the off-run HTTP path (the fix for the cross-transport mismatch where an MCP-created document was invisible in the Web UI). The route opens from substrate:admin to substrate:tenant; the per-tool gate inside the session still hides admin-only meta-tools. RFC AO adds config-declared static (tenant, subject) principals: a new principals: block in loomcycle.yaml binds a stable service identity to a token_env name; the bearer secret lives in .env.local. One declared bearer authenticates both /ui/login AND an MCP thin client at the same (tenant, subject) by construction. RFC AN makes --config repeatable with deep-merge, so bundles stack onto operator config without copy-paste. What it unlocks: the launch plan moved from a flat Markdown file to a Document with 18 publication chunks; status is a queryable typed field; agents and humans edit different chunks concurrently under optimistic-revision concurrency; Channel events fire on every chunk update. The natural agentic shape: scaffold → drafter agent → human review → posted → reporter agent. Additive on the substrate layer; no new wire RPCs; TS + Python adapters unchanged at 1.4.0; Claude Code plugin bumps to v1.5.0. Existing deployments without a principals: block keep working unchanged.", "url": "https://wpnews.pro/news/agents-and-humans-on-the-same-chunks-how-v1-5-0-made-co-authoring-possible", "canonical_source": "https://loomcycle.dev/blog/agents-and-humans-on-the-same-chunks.html", "published_at": "2026-06-30 17:33:39.034743+00:00", "updated_at": "2026-06-30 17:33:41.021289+00:00", "lang": "en", "topics": ["ai-agents", "developer-tools", "ai-tools"], "entities": ["loomcycle", "Claude Code"], "alternates": {"html": "https://wpnews.pro/news/agents-and-humans-on-the-same-chunks-how-v1-5-0-made-co-authoring-possible", "markdown": "https://wpnews.pro/news/agents-and-humans-on-the-same-chunks-how-v1-5-0-made-co-authoring-possible.md", "text": "https://wpnews.pro/news/agents-and-humans-on-the-same-chunks-how-v1-5-0-made-co-authoring-possible.txt", "jsonld": "https://wpnews.pro/news/agents-and-humans-on-the-same-chunks-how-v1-5-0-made-co-authoring-possible.jsonld"}}
