mcp_sqlite_memory_bank memory.instructions.md

Instructions for using a SQLite memory bank, a stored database of project context and decisions, during coding-agent sessions.

In plain words
What is it for?
Use it to search, store, and verify project knowledge through the configured memory system.
Why use it?
It helps the agent retrieve relevant past information and save important new context for later work.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp_sqlite_memory_bank memory.instructions.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

MEMORY MANAGEMENT INSTRUCTIONS (General Guidelines)

PRIME DIRECTIVE FOR MEMORY USAGE

  • ALWAYS SEARCH KNOWLEDGE BASE FIRST: Before proceeding with any task or answering questions, you MUST search available memory banks for relevant context, previous decisions, project structure, and user preferences.
  • You MUST use available memory systems to store all important contextual information learned during conversations.
  • You MUST retrieve relevant context from memory systems at the start of each new interaction.
  • Always design schemas that are explicit, discoverable, and LLM-friendly.
  • ALWAYS verify data storage and handle errors gracefully.
  • Use MCP tools consistently for all memory operations.

MEMORY MANAGEMENT PROTOCOL

SETUP & INITIALIZATION

  1. Check if required tables exist at the beginning of each session.
  2. Create missing tables with appropriate schemas before storing data.
  3. When creating tables, follow these naming conventions:
    • Use snake_case for table and column names
    • Use descriptive, semantic names
    • Include appropriate primary keys and constraints

STORAGE & RETRIEVAL

  1. Store information immediately after learning it.
  2. Categorize information appropriately in the correct tables.
  3. Before answering questions, query relevant tables for context.
  4. Use specific WHERE clauses to retrieve only relevant information.
  5. LEVERAGE SEMANTIC SEARCH: Use semantic search capabilities for intelligent knowledge discovery when exact matches aren't sufficient.

SCHEMA MAINTENANCE

  1. Maintain consistent schemas across sessions.
  2. Update existing records rather than creating duplicates.
  3. Use appropriate data types for columns.
  4. Create relationships between tables when appropriate.
  5. Drop tables only when they are no longer needed, and document the reason for deletion.
  6. Regularly review and refactor schemas to improve clarity and efficiency.

SEMANTIC SEARCH CAPABILITIES (IF AVAILABLE)

OVERVIEW

Many memory systems support intelligent semantic search using sentence-transformers for natural language queries and content discovery. This enables agents to find conceptually similar content even when exact keyword matches don't exist.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
