Memory - Read & Access Operations

Unified read-side memory skill with subcommands for searching, loading, syncing, history, and visualization.

Argument Resolution

SUBCOMMAND = "$ARGUMENTS[0]"  # First token: search, load, history, viz, status
QUERY = "$ARGUMENTS[1]"       # Second token onward: search query or flags
# $ARGUMENTS is the full string (CC 2.1.59 indexed access)

Usage

/ork:memory search <query>  # Search knowledge graph
/ork:memory load             # Load context at session start
/ork:memory history          # View decision timeline
/ork:memory viz              # Visualize knowledge graph
/ork:memory status           # Show memory system health

CRITICAL: Use AskUserQuestion When No Subcommand

If invoked without a subcommand, ask the user what they want:

AskUserQuestion(
  questions=[{
    "question": "What memory operation do you need?",
    "header": "Operation",
    "options": [
      {"label": "search", "description": "Search decisions and patterns in knowledge graph", "markdown": "```\nSearch Knowledge Graph\n──────────────────────\n  query ──▶ mcp__memory ──▶ results\n\n  Flags:\n  --category  Filter by type\n  --agent     Scope to agent\n  --limit N   Max results\n  --global    Cross-project\n```"},
      {"label": "load", "description": "Load relevant context for this session", "markdown": "```\nLoad Session Context\n────────────────────\n  Auto-detect project ──▶\n  ┌────────────────────┐\n  │ Recent decisions   │\n  │ Active patterns    │\n  │ Project entities   │\n  └────────────────────┘\n  Flags: --project, --global\n```"},

      {"label": "viz", "description": "Visualize knowledge graph as Mermaid", "markdown": "```\nKnowledge Graph Viz\n───────────────────\n  Entities ──▶ Mermaid diagram\n\n  [Project] ──uses──▶ [Postgres]\n      │                    │\n      └──has──▶ [Auth] ──uses──▶ [JWT]\n\n  Output: Mermaid code block\n```"},
      {"label": "status", "description": "Check memory system health", "markdown": "```\nMemory Health Check\n───────────────────\n  ┌─────────────────────┐\n  │ MCP server    ✓/✗   │\n  │ Entity count  N     │\n  │ Relation count N    │\n  │ Last write    date  │\n  │ Graph size    N KB  │\n  └─────────────────────┘\n```"}
    ],
    "multiSelect": false
  }]
)

Subcommands

Load details: Read("${CLAUDE_SKILL_DIR}/references/memory-commands.md") for full usage, flags, output formats, and context-aware result limits for each subcommand.

Workflow

1. Parse Subcommand

Extract first argument as subcommand
If no subcommand -> AskUserQuestion
Validate subcommand is one of: search, load, history, viz, status
Parse remaining flags
Check for --agent <agent-id> flag → agent_id: "ork:{agent-id}"

2. Execute Subcommand

Route to appropriate handler based on subcommand.

3. Report Results

Format output appropriate to the operation.

Rules Quick Reference

Session Resume

Load details: Read("${CLAUDE_SKILL_DIR}/references/session-resume-patterns.md") for CC 2.1.31 resume hints, context capture before ending, and resume workflows for PRs, issues, and implementations.

Error Handling

• If graph empty for viz: Show helpful message about using /ork:remember
• If subcommand invalid: Show usage help
• If memory files corrupt: Report and offer repair
• If search query empty: Show recent entities instead
• If no search results: Suggest alternatives
