Memory
Memory is imported but never referenced anywhere in this file. This will cause a TypeScript/lint warning and should be removed.

runtime parameter is unused — core logic is missing
The runtime: IAgentRuntime parameter is passed in but never used inside the method. The inline comment // Logic to partition memory and state by userId signals that the actual implementation was intended but never written. As a result, this method does nothing beyond generating an ID object — it does not actually isolate memory, partition state, or prevent context leakage in any way, which directly contradicts the PR description.
For the feature to deliver on its stated goal, runtime must be used to scope/retrieve memories per userId, for example via runtime.getMemory(...) or equivalent. Without this, the SessionManager provides no functional benefit over a plain UUID generator, and deploying it could give a false sense of multi-user isolation.

console.log should use the runtime logger
Using console.log bypasses the agent runtime's structured logging system (log levels, transports, etc.). Prefer the runtime's logger so log output can be filtered and controlled consistently across the codebase.

Date.now() collision risk in concurrent environments
If two sessions are created for the same userId within the same millisecond (e.g., rapid reconnects), the generated sessionId will be identical: session-<userId>-<sameTimestamp>. This can silently cause session ID collisions. Consider using a UUID (e.g., crypto.randomUUID()) to guarantee uniqueness:
| sessionId: `session-${userId}-${Date.now()}`, | |
| sessionId: `session-${userId}-${crypto.randomUUID()}`, |
| export class SessionManager { | ||

The class only exposes createSession with no way to retrieve an existing session, list active sessions, or destroy/expire one. For multi-user support in Discord/Telegram bots (as described in the PR), you typically need at minimum:
getSession(userId)— retrieve an existing session or create onedestroySession(sessionId)— clean up when a user disconnects- A storage map (or persistent store) to hold live sessions
Without these, callers have no way to associate subsequent messages from the same user with their previously created session, which defeats the stated purpose of isolated context windows.

We reviewed this and did not carry it. The current implementation is still not merge-ready: it sketches a SessionManager, but it does not yet provide real multi-user session isolation, storage integration, or end-to-end coverage proving the behavior claimed in the PR. Please resubmit with a real runtime integration path and tests that exercise actual session separation. |

Greptile Summary
This PR adds a new
SessionManagerclass topackages/core/src/sessions/intended to provide per-user session isolation for multi-user bot deployments. However, the implementation is a stub — the singlecreateSessionmethod only generates a session ID object and contains no actual partitioning, memory scoping, or context isolation logic.Key issues:
runtime: IAgentRuntimeparameter andMemoryimport are both completely unused, indicating the core logic was never implemented.Date.now()is used for session ID generation, which is collision-prone under concurrent load;crypto.randomUUID()would be safer.console.logshould use the runtime's structured logger.index.ts, so it is currently unreachable by consumers.Confidence Score: 1/5
SessionManagerAPI into core that silently does nothing while giving callers a false guarantee of user isolation — a critical correctness problem for public bot deployments.Important Files Changed
