Copilotkit Foundation

Use when building a multi-platform chat/channel agent runtime (Slack, Teams, Discord, Telegram, WhatsApp) or cross-platform UI bridge — dynamic Proxy subscriber fanouts, isolated error boundaries between runners and renderers, symbol-branded terminal delivery errors, durable action registry rehydration with payload-limited value caching, thread promise conversion boundaries, stream null-string sanitization for LangGraph tool interrupts, sentinel-based Markdown-to-mrkdwn pipelines, per-platform transport planes (Discord ack-race chunking, Teams proactive turns + Adaptive Cards, WhatsApp signed webhooks), core RunHandler run-loop contracts, realtime-gateway connection-health machinery, channel-delivery packet transport stack, and universal UI Intermediate Representation (IR) AST expanders. Source code and direct tests are ground truth; references carry decisive excerpts and graph retrieval.

copilotkit: Multi-Channel Agent & UI Runtime Foundation

Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is historical, revision-pinned evidence rather than timeless guidance. Current project source, tests, requirements, and runtime behavior outrank this projection and decide what ships.

Provenance and revision

Source record: copilotkit; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: main@e9387e04835545c45744b791aee7c9c03520be31.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Agent Run Loop & Event Fanout; Delivery Error & Promise Boundaries; UI Actions & State Rehydration; Channel Formatting & UI AST; Telegram Transport Plane; Discord Transport Plane; Teams Transport Plane; Teams Rendering Plane.
Scope and retrieval questions: references/index.md#use-this-for.
Complete capsule chooser: references/index.md#load-the-matching-source-dump.
Detailed grouped map: references/index.md#capsule-map.
Source limitations and portability boundaries: references/index.md#boundaries.

Retrieval

Open the index, choose one capsule matching the active question, and load only that capsule. Revalidate its cited source and revision before relying on it. Do not bulk-load the inventory, treat historical claims as current truth, or apply this foundation as a procedure.
