SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Cipher MCP memory saves silently fail due to an unconfigured significance filter, overly aggressive default dedup thresholds, and confusion between three separate memory systems, leading to lost session work, endless retry loops, and no clear error messages to diagnose root causes.

Core Features & Use Cases

  • Deterministic Save Protocol: Step-by-step workflow for all three Cipher memory tools (knowledge, workspace, reasoning) with pre-flight search to avoid unnecessary saves and dedup confusion.
  • Significance Filter Patch: Fixes the hardcoded Cipher 0.3.0 bug that discards valid technical content (e.g., content mentioning "email", "address", or non-English terms) as "non-significant" with no warning.
  • Failure Recovery Workflows: Clear, step-by-step recovery for dedup skips and LLM extraction failures, with strict retry limits to avoid infinite loops.
  • Use Case: Ideal for developers using Cipher MCP for session memory who experience silent save failures, need to persist technical decisions, session progress, or reasoning traces reliably.

Quick Start

Use the cipher-memory-expert skill to save the Redis cache TTL decision we just made to Cipher knowledge memory, verify it was stored successfully, and report the result to me.

FAQPage Schema
Why does Cipher MCP silently fail to save my session memory without throwing an error?

Cipher MCP memory saves silently fail when an unconfigured significance filter or aggressive default dedup thresholds discard valid content without returning an error message. This issue also stems from confusion between the three separate memory systems, causing lost session work.

How do I stop dedup skips and extracted:0 responses when saving technical content to Cipher memory?

To stop dedup skips and extracted:0 responses, use a deterministic save protocol with pre-flight searches and a fixed 0.95 similarity threshold. This approach prevents unnecessary saves and resolves LLM extraction failures that incorrectly discard valid technical content.

What is the best way to patch the Cipher significance filter that blocks valid technical content?

The best way to patch the Cipher significance filter is applying a targeted fix for the hardcoded bug that incorrectly flags valid content mentioning terms like email or non-English text as non-significant, ensuring technical decisions are persisted reliably.

How do I recover from infinite retry loops during Cipher knowledge or workspace memory saves?

Recover from infinite retry loops by following strict step-by-step failure recovery workflows for LLM extraction failures and dedup skips. These workflows enforce strict retry limits to prevent endless loops when persisting reasoning traces.

Does Cipher MCP support saving session progress across all three memory systems simultaneously?

Yes, Cipher MCP supports saving session progress across knowledge, workspace, and reasoning memory systems. A unified deterministic protocol with atomic content formatting ensures reliable persistence across all three systems without silent failures.

What are the limitations of using Cipher MCP default thresholds for memory persistence?

The limitations of Cipher MCP default thresholds include overly aggressive dedup settings and a hardcoded 0.3.0 significance filter bug that discards valid content. These unconfigured defaults result in lost session work and no clear error messages.
