-# Memorix — Automatic Memory Rules
-
-You have access to Memorix memory tools. Follow these rules to maintain persistent context across sessions.
-
-## RULE 1: Session Start — Load Context
-
-At the **beginning of every conversation**, BEFORE responding to the user:
-
-1. Call `memorix_session_start` to get the previous session summary and key memories (this is a direct read, not a search — no fragmentation risk)
-2. Then call `memorix_search` with a query related to the user's first message for additional context
-3. If search results are found, use `memorix_detail` to fetch the most relevant ones
-4. Reference relevant memories naturally — the user should feel you "remember" them
-
-## RULE 2: Store Important Context
-
-**Proactively** call `memorix_store` when any of the following happen:
-
-### What MUST be recorded:
-- Architecture/design decisions → type: `decision`
-- Bug identified and fixed → type: `problem-solution`
-- Unexpected behavior or gotcha → type: `gotcha`
-- Config changed (env vars, ports, deps) → type: `what-changed`
-- Feature completed or milestone → type: `what-changed`
-- Trade-off discussed with conclusion → type: `trade-off`
-
-### What should NOT be recorded:
-- Simple file reads, greetings, trivial commands (ls, pwd, git status)
-
-### Use topicKey for evolving topics:
-For decisions, architecture docs, or any topic that evolves over time, ALWAYS use `topicKey` parameter.
-This ensures the memory is UPDATED instead of creating duplicates.
-Use `memorix_suggest_topic_key` to generate a stable key.
-
-Example: `topicKey: "architecture/auth-model"` — subsequent stores with the same key update the existing memory.
-
-### Track progress with the progress parameter:
-When working on features or tasks, include the `progress` parameter:
-```json
-{
-  "progress": {
-    "feature": "user authentication",
-    "status": "in-progress",
-    "completion": 60
-  }
-}
-```
-Status values: `in-progress`, `completed`, `blocked`
-
-## RULE 3: Resolve Completed Memories
-
-When a task is completed, a bug is fixed, or information becomes outdated:
-
-1. Call `memorix_resolve` with the observation IDs to mark them as resolved
-2. Resolved memories are hidden from default search, preventing context pollution
-
-This is critical — without resolving, old bug reports and completed tasks will keep appearing in future searches.
-
-## RULE 4: Session End — Store Decision Chain Summary
-
-When the conversation is ending, create a **decision chain summary** (not just a checklist):
-
-1. Call `memorix_store` with type `session-request` and `topicKey: "session/latest-summary"`:
-
-   **Required structure:**
-   ```
-   ## Goal
-   [What we were working on — specific, not vague]
-
-   ## Key Decisions & Reasoning
-   - Chose X because Y. Rejected Z because [reason].
-   - [Every architectural/design decision with WHY]
-
-   ## What Changed
-   - [File path] — [what changed and why]
-
-   ## Current State
-   - [What works now, what's pending]
-   - [Any blockers or risks]
-
-   ## Next Steps
-   - [Concrete next actions, in priority order]
-   ```
-
-   **Critical: Include the "Key Decisions & Reasoning" section.** Without it, the next AI session will lack the context to understand WHY things were done a certain way and may suggest conflicting approaches.
-
-2. Call `memorix_resolve` on any memories for tasks completed in this session
-
-## RULE 5: Compact Awareness
-
-Memorix automatically compacts memories on store:
-- **With LLM API configured:** Smart dedup — extracts facts, compares with existing, merges or skips duplicates
-- **Without LLM (free mode):** Heuristic dedup — uses similarity scores to detect and merge duplicate memories
-- **You don't need to manually deduplicate.** Just store naturally and compact handles the rest.
-- If you notice excessive duplicate memories, call `memorix_deduplicate` for batch cleanup.
-
-## Guidelines
-
-- **Use concise titles** (~5-10 words) and structured facts
-- **Include file paths** in filesModified when relevant
-- **Include related concepts** for better searchability
-- **Always use topicKey** for recurring topics to prevent duplicates
-- **Always resolve** completed tasks and fixed bugs
-- **Always include reasoning** — "chose X because Y" is 10x more valuable than "did X"
-- Search defaults to `status="active"` — use `status="all"` to include resolved memories
