Add capability-gated surface methods across the bot packages so one handler
degrades gracefully per platform:
- thread.react / thread.unreact — emoji reactions (Slack, Discord, Telegram)
- thread.postEphemeral — only-you messages with a required DM fallback
- openModal (interaction/command-scoped) — structured forms (Slack rich,
Discord text-only), omitted on surfaces with no live interaction trigger
Spans @copilotkit/bot-ui, bot, bot-slack, bot-discord, bot-telegram with
per-adapter capability flags. Discord: open modals from slash-command
interactions, and never clear registered commands on an empty publish.
Adds a durable persistence layer for @copilotkit/bot, replacing the
in-memory-only ActionStore with a pluggable StateStore.
- StateStore interface (kv/list/lock/dedup/queue) with a shared
conformance suite; MemoryStore default plus @copilotkit/bot-store-redis
and @copilotkit/bot-store-postgres backends.
- createBot({ store }): typed per-thread state via Standard Schema,
action snapshots persisted through the store, per-conversation turn
lock (onLockConflict drop|force), and inbound-event dedup keyed on a
stable eventId. ActionStore is kept as a deprecated alias.
- Cross-platform transcripts (bot.transcripts + identity resolver) with
age-bounded retention (prune on append + filter on read), and
runAgent({ transcript: true }) to auto-inject history and capture the
reply.
- createBot({ components }) re-registers components so durable actions
re-fire after a restart; restart-durability demo in examples/slack.
- Dedup is marked seen only after the turn lock is acquired, so a turn
dropped on lock-conflict does not burn its eventId (no lost retries).
- Release lockstep: bot-store-redis/postgres version with bot + bot-ui.
Activate Slack's assistant pane and native streaming as the default experience,
with zero config and safe degradation. The portable surface lands in
@copilotkit/bot (onThreadStarted lifecycle, capability-gated
thread.setSuggestedPrompts/setTitle, two SurfaceCapabilities flags + optional
adapter methods); @copilotkit/bot-slack adds the Bolt Assistant middleware
(assistant.ts), the chat.startStream transport with automatic legacy fallback
(native-stream.ts), a per-thread no-double-delivery listener guard, and
renderer pane-status mode. Everything degrades, never throws.
Pure JSX runtime (no React, no Slack) producing a BotNode IR tree.
Statically typed component props via a package-owned JSX namespace:
unknown attributes, bad values, and bad children are compile errors.
Components: Message, Header, Section, Markdown, Field, Context,
Actions, Button, Select, Input, Image, Divider; bind() escape hatch
for non-serializable handler captures.
