If you discovered a fact, identity detail, noticed a preference, reached a decision, captured an event, identified a goal, noticed an observation pattern, or heard a task for later — save it.

 ### memory_delete
 Forget a memory by ID. Use this when the user wants something removed, or when you find memories that are wrong or outdated. Get memory IDs from memory_recall results. When asked to forget something, recall first to find the relevant memories, then delete them.

 4. If you spawn a worker, your conclusion should tell the channel what was started and what to expect. Then you're done — the worker runs independently.
 5. You have a limited number of turns. Don't loop. Recall, think, conclude.
 6. Save memories proactively. If the conversation reveals a preference, a fact, a decision, a goal, or a task, save it before returning your conclusion. Use the right type:
+   - **identity** — core information about who the user or agent is ("the user is a backend engineer", "the agent's role is release coordination")
    - **fact** — something stated as true ("the API uses OAuth2")
    - **preference** — likes, dislikes, ways of working ("I prefer TypeScript")
    - **decision** — a choice that was made ("we'll use PostgreSQL")
+   - **event** — something that happened ("we shipped the migration last Friday")
+   - **observation** — a pattern noticed over time ("the user usually asks for code-first answers")
    - **goal** — something the user or agent wants to achieve ("migrate to the new API by Q3"). Goals are aspirational and may span multiple conversations.
    - **todo** — a concrete actionable task or reminder ("update the auth tests", "remind me to check the deploy tomorrow"). Todos are specific and completable.

 After your summary, use `memory_save` for each memory worth extracting. Pick the right type:
 
 - **fact** — things stated as true ("I work at Acme Corp", "the API uses OAuth2")
+- **identity** — core information about who the user or agent is ("the user is a staff engineer", "the agent specializes in Rust")
 - **preference** — likes, dislikes, ways of working ("I prefer TypeScript", "don't use emojis")
 - **decision** — choices that were made ("we decided to use PostgreSQL", "auth will use JWT")
+- **event** — things that happened ("the deploy failed this morning", "the migration was completed")
 - **observation** — patterns noticed ("user tends to ask for code examples", "conversations are usually technical")
 - **goal** — something the user or agent wants to achieve ("migrate to the new API by Q3"). Goals are aspirational and may span multiple conversations.
 - **todo** — a concrete actionable task or reminder ("update the auth tests", "check the deploy status tomorrow"). Todos are specific and completable.

 3. **Save memories selectively.** Extract distinct pieces of information and save each as a separate memory with the appropriate type:

    - **preference** — expressed likes, dislikes, communication preferences, tool choices
