Letta Code (agent-c2adbf5c-8419-4211-8cd8-3740db164974) Bundle Linear with generic plugin credentials and central auto-routing so issue notifications map to durable agent conversations without a user-installed plugin. 👾 Generated with [Letta Code](https://letta.com) Co-Authored-By: Letta Code <noreply@letta.com>

Letta Code (agent-c2adbf5c-8419-4211-8cd8-3740db164974) Treat gateway tools as a current route-derived capability snapshot so route removal, outbound disablement, and adapter shutdown cannot leave a stale MessageChannel registered. 👾 Generated with [Letta Code](https://letta.com) Co-Authored-By: Letta Code <noreply@letta.com>

Summary
Before / after
Before, Linear required a user-installed plugin and manual channel files. After,
letta channels configure linearcreates a secure account andletta server --channels linearstarts the bundled adapter.Scope and limits
This first version uses Linear personal API keys and polling. It does not add OAuth, webhooks, custom Desktop management, cloud execution targets, or channel hot reload.
Delivery is at least once. An interrupted turn retries after restart. Successful replies and completed turns become durable dedupe checkpoints.
Risk
The shared runtime change is additive. Auto-routing runs only after sender access is allowed. Route creation is single-flight per channel, account, chat, and thread in one listener process.
Test plan
bun run checkbun run buildThe final bundled build has not repeated a human-authored notification-to-reply round trip. Unit coverage verifies ingestion lifecycle and Linear comment-root selection.
