Code Memory Router — Development skill for Claude Code

code-memory-router


A Claude Code skill that routes memory and retrieval tasks to the right tool — **MemPalace** for project memory, **QMD** for codebase search.

---

The problem

Without routing guidance, Claude defaults to `grep` for everything — even questions like *"why did we build it this way?"* or *"what did we decide last week?"*. That burns tokens, misses the answer, and ignores the memory systems you set up.

The solution

This skill teaches Claude:

• WHERE something is in code → use QMD (hybrid BM25 + semantic search)
• WHY something exists or was decided → use MemPalace (persistent project memory)
• BOTH → combined flow, code-first or history-first depending on the question

Benchmark

Tested on 3 real tasks across 6 parallel runs (with skill vs without):

Task	With skill	Without skill
Find WebSocket disconnect handler in Rust backend	4/4 ✅	1/4 ❌
Why did we switch from SSE to WebSocket?	4/4 ✅	1/4 ❌
Show AI chat entry point + architecture decisions	5/5 ✅	2/5 ❌
Total	13/13	4/13
Avg tokens (memory tasks)	36k	58k (+61%)
Avg time (memory tasks)	175s	339s (+94%)

Without the skill, agents missed MemPalace entirely on every memory task — burning 61% more tokens to find the same answer via brute-force grep.

Requirements

• QMD — codebase indexer with hybrid search
• MemPalace — persistent AI memory

Both must be installed and indexed. See [references/setup-guide.md](references/setup-guide.md).
