Remember - Store Decisions and Patterns

Store important decisions, patterns, or context in the knowledge graph for future sessions. Supports tracking success/failure outcomes for building a Best Practice Library.

Argument Resolution

TEXT = "$ARGUMENTS"        # Full argument string, e.g., "We use cursor pagination"
FLAG = "$ARGUMENTS[0]"     # First token — check for --success, --failed, --category, --agent
# Parse flags from $ARGUMENTS[0], $ARGUMENTS[1] etc. (CC 2.1.59 indexed access)
# Remaining tokens after flags = the text to remember

Architecture

The remember skill uses knowledge graph as storage:

1. Knowledge Graph: Entity and relationship storage via mcp__memory__create_entities and mcp__memory__create_relations - FREE, zero-config, always works

Benefits:

• Zero configuration required - works out of the box
• Explicit relationship queries (e.g., "what does X use?")
• Cross-referencing between entities
• No cloud dependency

Automatic Entity Extraction:

• Extracts capitalized terms as potential entities (PostgreSQL, React, pgvector)
• Detects agent names (database-engineer, backend-system-architect)
• Identifies pattern names (cursor-pagination, connection-pooling)
• Recognizes "X uses Y", "X recommends Y", "X requires Y" relationship patterns

Usage

Store Decisions (Default)

/ork:remember <text>
/ork:remember --category <category> <text>
/ork:remember --success <text>     # Mark as successful pattern
/ork:remember --failed <text>      # Mark as anti-pattern
/ork:remember --success --category <category> <text>

# Agent-scoped memory
/ork:remember --agent <agent-id> <text>         # Store in agent-specific scope
/ork:remember --global <text>                   # Store as cross-project best practice

Flags

Categories

• decision - Why we chose X over Y (default)
• architecture - System design and patterns
• pattern - Code conventions and standards
• blocker - Known issues and workarounds
• constraint - Limitations and requirements
• preference - User/team preferences
• pagination - Pagination strategies
• database - Database patterns
• authentication - Auth approaches
• api - API design patterns
• frontend - Frontend patterns
• performance - Performance optimizations

Outcome Flags

• --success - Pattern that worked well (positive outcome)
• --failed - Pattern that caused problems (anti-pattern)

If neither flag is provided, the memory is stored as neutral (informational).

Workflow

1. Parse Input

Check for --success flag → outcome: success
Check for --failed flag → outcome: failed
Check for --category <category> flag
Check for --agent <agent-id> flag → agent_id: "ork:{agent-id}"
Check for --global flag → use global user_id
Extract the text to remember
If no category specified, auto-detect from content

2. Auto-Detect Category

3. Extract Lesson (for anti-patterns)

If outcome is "failed", look for:

• "should have", "instead use", "better to"
• If not found, prompt user: "What should be done instead?"

4-6. Extract Entities and Create Graph

Extract entities (Technology, Agent, Pattern, Project, AntiPattern) from the text, detect relationship patterns ("X uses Y", "chose X over Y", etc.), then create entities and relations in the knowledge graph.

Load entity extraction rules, type assignment, relationship patterns, and graph creation examples: Read("${CLAUDE_SKILL_DIR}/references/graph-operations.md")

7. Confirm Storage

Display confirmation using the appropriate template (success, anti-pattern, or neutral) showing created entities, relations, and graph stats.

Load output templates and examples: Read("${CLAUDE_SKILL_DIR}/references/confirmation-templates.md")

File-Based Memory Updates

When updating .claude/memory/MEMORY.md or project memory files:

• PREFER Edit over Write to preserve existing content and avoid overwriting
• Use stable anchor lines: ## Recent Decisions, ## Patterns, ## Preferences
• See the memory skill's "Permission-Free File Operations" section for the full Edit pattern
• This applies to the calling agent's file operations, not to the knowledge graph operations above

Error Handling

• Knowledge graph unavailable → show configuration instructions
• Empty text → ask user for content; text >2000 chars → truncate with notice
• Both --success and --failed → ask user to clarify
• Entity extraction fails → create generic Decision entity; relation fails → create entities first, retry
