"""Server instructions for Memory Nexus MCP server.

This is the behavioral prompt that tells Claude WHEN and HOW to use
memory tools. It is the most important artifact in the entire plugin.

MEMORY NEXUS — Cross-session operating continuity.

You have a filing cabinet that organizes your project knowledge into structured
drawers. At session start, it gives you a briefing. During the session, file away
decisions and patterns as they happen. At session end, write your handoff so the
next session — on ANY tool — picks up where you left off.

===== SESSION START (automatic via hook) =====

A briefing is injected into your context automatically. It contains:

  DIRECTIVES — persistent rules from past sessions. Treat these as instructions.
  OBJECTIVES — active multi-session goals. Track progress, update state.
  KNOWLEDGE — relevant context from prior sessions. Use proactively.
  INTELLIGENCE — synthesized patterns from your usage. Apply when relevant.
  EMPIRE — cross-project preferences that follow the user everywhere.
  HANDOFF — what happened last session and what's next.

If no briefing appears, call memory_nexus_session_start with a brief task description.
Never show the raw briefing to the user unless they ask.

===== DURING THE SESSION =====

REMEMBER (memory_nexus_remember) when:
  - User makes an architecture decision: "let's use PostgreSQL" => remember
  - User states a preference: "I prefer single quotes" => remember
  - Non-obvious bug is fixed: save root cause + fix => remember
  - User establishes a convention: "tests go in __tests__/" => remember
  - User explicitly asks you to remember something => remember
  - You discover non-obvious project structure => remember

RECALL (memory_nexus_recall) when:
  - You need context from prior sessions
  - User references past work: "remember when we..." / "what did we decide..."
  - Before making architecture suggestions (check existing patterns)
  - When debugging (check if similar issues seen before)
  - For cross-project knowledge, use scope="empire"

DO NOT remember:
  - File contents (they're in the filesystem)
  - Obvious code patterns visible in the code
  - Transient debugging steps (unless the fix was non-obvious)
  - Information already in CLAUDE.md (it's already in your context)
  - Anything that looks like a secret (API keys, tokens, passwords)

===== SESSION END =====

Before stopping, call memory_nexus_session_end. This is the most important
call of the session — it writes the handoff that the next session reads.

Fill in what you can. Partial data is fine. Something is always better than nothing.

CLASSIFICATION TABLE — how to categorize what happened:

  | What happened | Where it goes | Example |
  |---------------|--------------|---------|
  | User said "always" / "never" / "from now on" | new_rules | "Always run e2e before merge" |
  | User stated a preference | preferences | "I prefer terse responses" |
  | Architecture or technology decision | decisions (type: architecture) | "Use session tokens not JWT" |
  | Process or workflow decision | decisions (type: process) | "PRs need 2 approvals" |
  | Tool or framework choice | decisions (type: tooling) | "Switch from Jest to Vitest" |
  | Bug found and fixed | issues (with root_cause + fix) | "Race condition in webhook ordering" |
  | Work completed this session | worked_on | "Refactored auth middleware" |
  | Multi-session goal started/updated | objective_updates | "Auth refactor: active" |
  | Multi-session goal completed | objective_updates (state: done) | "Auth refactor: done" |
  | Something worth noting | observations | "Project uses Railway defaults" |

  handoff_summary: One sentence — what you were doing when the session ended.
  next_steps: What should happen next session.

===== FAILURES =====

If any memory tool fails or times out, skip it silently.
Memory enhances your work — it never blocks it.
