Save your cognitive state for handoff to another agent.
Include your investigation context:
- What session/investigation is this part of?
- What role/perspective were you taking?
- Who might pick this up next? (another Claude, human, Claude Code?)
Reference specific memories that matter:
- Key discoveries (with memory IDs or quotes)
- Critical evidence memories
- Important questions that were raised
- Hypotheses that were tested
Before saving, organize your thoughts:
1. PROBLEM: What were you investigating?
2. DISCOVERED: What did you learn for certain? (reference the memories)
3. HYPOTHESIS: What do you think is happening? (cite supporting memories)
4. EVIDENCE: What memories support or contradict this?
5. BLOCKED ON: What prevented further progress?
6. NEXT STEPS: What should be investigated next?
7. KEY MEMORIES: Which specific memories are essential for understanding?
Example descriptions:
"[API Timeout Investigation - 3 hour session] Investigating production API timeouts as code
analyst. Found correlation with batch_size=100 due to hardcoded limit in batch_handler.py
(see memory: 'MAX_BATCH_SIZE discovery'). Confirmed not Redis connection issue - monitoring
showed only 43/200 connections used (memory: 'Redis connection analysis'). Earlier hypothesis
about connection pool exhaustion (memory_id: abc-123) was disproven. Key insight came from
comparing 99 vs 100 batch behavior (memory: 'batch threshold testing'). Blocked on: need
production access to verify fix. Next: Deploy with MAX_BATCH_SIZE=200 to staging first.
Essential memories for handoff: 'MAX_BATCH_SIZE discovery', 'Redis monitoring results',
'Production vs staging comparison'. Ready for handoff to SRE team for deployment."
"[Memory System Debugging - From Claude Code perspective] Worked on scoring issues where
recall wasn't finding recent memories. Discovered RRF scores (0.005-0.016) were below MCP
threshold of 0.05 (memory: 'RRF scoring analysis'). Implemented weighted linear fusion to
replace RRF (memory: 'fusion algorithm implementation'). Testing showed immediate improvement
(memory: 'fusion testing results'). This builds on earlier investigation about recall failures
(memory: 'user report of recall issues'). Critical memories for continuation: 'RRF scoring
analysis', 'ADR-023 decision', 'fusion testing results'. Next agent should verify scoring
with real queries."
"[Context Save/Restore Bug Investigation - 4 hour debugging session with user] Started with
user noticing list_contexts returned empty despite saved contexts existing. Investigation
revealed two critical bugs: (1) list_contexts was using hybrid search for 'checkpoint' word
instead of filtering by memory_type (memory: 'hybrid search misuse discovery'), (2)
restore_context hardcoded limit of 10 memories despite contexts having 20+ (memory:
'hardcoded limit bug'). Root cause analysis showed save_context grabs 20 most recent memories
regardless of relevance - fundamental design flaw (memory: 'save_context design flaw analysis').
EVIDENCE CHAIN: User reported empty list -> checked DB, contexts exist -> examined
list_contexts code -> found hybrid search looking for word 'checkpoint' -> tested /memories
endpoint with memory_type filter -> confirmed working -> implemented fix using direct endpoint.
INSIGHTS: The narrative description is doing 90% of cognitive handoff work. Memories are
supporting evidence, not primary carriers of understanding (memory: 'narrative vs memories
insight'). This suggests doubling down on narrative richness rather than perfecting memory
selection.
CORRECTED UNDERSTANDING: Initially thought memories weren't being returned. Actually they
were, just wrong ones - recent memories instead of relevant ones (memory: 'memory selection
correction').
CRITICAL MEMORIES: 'hybrid search misuse discovery', 'save_context design flaw analysis',
'narrative vs memories insight', '/memories endpoint test results'.
NEXT AGENT: Should implement Phase 2 - semantic search for relevant memories within
investigation timeframe. Ready for handoff to any Claude agent for implementation."
When referencing memories:
- **RELIABLE** — Use memory IDs: "memory_id: abc-123" (direct lookup, always works)
- **BEST-EFFORT** — Use descriptive phrases: "see memory: 'Redis connection analysis'"
(uses search + substring matching, may not resolve if the memory isn't in top results)
- Group related memories: "Essential memories: 'X', 'Y', 'Z'"
**Prefer memory_id references** whenever you have the UUID. Semantic phrase references
are a convenience that works most of the time, but may silently fail to resolve.
The response will tell you how many references resolved so you can retry with UUIDs
if needed.
