What it does

Memory Recall is an agent skill from zilliztech/memsearch. Search and recall relevant memories from past sessions via memsearch. Use when the user's question could benefit from historical context, past decisions, debugging notes, previous conversations, or project knowledge -- especially questions like 'what did I decide about X', 'why did we do Y', or 'have I seen this before'. Also use when you see [memsearch] Memory available hints injected via SessionStart or UserPromptSubmit. Typical flow: search for 3-5 chunks, expand the most relevant, optionally deep-drill into…

Its SKILL.md is about 810 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering. It works with Milvus and DeepSeek. The repository describes itself as: A persistent, unified memory layer for all your AI agents (e.g. Claude Code, Codex, DSH), backed by Markdown and Milvus. The licence is MIT.

When your agent uses it

  • The users question could benefit from historical context
  • Debugging notes
  • Previous conversations
  • Project knowledge -- especially questions like what did I decide about X

Example prompts

  • “what did I decide about X”
  • “why did we do Y”
  • “have I seen this before”
  • “/memory-recall”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. memory_search — Start here
  2. memory_get — When search results aren't detailed enough
  3. memory_transcript — When you need the exact original conversation

What it can do on your machine

Read from SKILL.md and the folder at commit 2a4652f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Memory Recall loads about 807 tokens when it runs. Until then it costs about 183 tokens; SKILL.md has 325 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~183
When it runs · the whole SKILL.md, loaded when a task matches
~807

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Search and recall relevant memories from past sessions via memsearch. Use when the user's question could benefit from historical context, past decisions, debugging notes, previous conversations, or project knowledge -- especially questions like 'what did I decide about X', 'why did we do Y', or 'have I seen this before'. Also use when you see `[memsearch] Memory available` hints injected via SessionStart or UserPromptSubmit. Typical flow: search for 3-5 chunks, expand the most relevant, optionally deep-drill into original transcripts via the anchor format. Skip when the question is purely about current code state (use Read/Grep), ephemeral (today's task only), or the user has explicitly asked to ignore memory.

You have three memory tools for progressive recall. Start with search, go deeper only when needed.

Tools (use progressively)

1. memory_search — Start here

Semantic search across all past conversation memories.

  • Returns: chunk summaries with dates, topics, chunk_hash identifiers
  • Use for: "What did we discuss about X?", "Have I asked about Y before?"
2. memory_get — When search results aren't detailed enough

Expands a specific chunk_hash to show the full markdown section with surrounding context.

  • Input: chunk_hash from memory_search results
  • Returns: full section text, may include transcript anchors (<!-- session:UUID transcript:PATH -->)
  • Use for: "Show me the details", "I need more context on that result"
3. memory_transcript — When you need the exact original conversation

Parses the original session transcript to retrieve the raw dialogue.

  • Input: transcript_path from the anchor comment in memory_get results
  • Returns: formatted conversation with [User]/[Assistant] labels and tool calls
  • Use for: "What exactly did I say?", "Show me the original conversation"
  • If the anchor format is unfamiliar (e.g. rollout:, turn:, db: instead of transcript:), try reading the referenced file directly to explore its structure and locate the relevant conversation by the session or turn identifiers in the anchor.

Decision guide

User intentTools to use
Quick recall ("did we discuss X?")memory_search only
Need details ("what was the solution?")memory_search → memory_get
Need original dialogue ("show me the exact conversation")memory_search → memory_get → memory_transcript

Tips

  • memory_search returns chunk_hash — pass it to memory_get for expansion
  • memory_get may reveal <!-- session:UUID transcript:PATH --> anchors — pass the path to memory_transcript
  • If memory_search returns no results, try rephrasing with different keywords
  • Results are sorted by relevance (hybrid BM25 + vector search)

The SessionStart injection already shows you a heading-level preview of recent memory files — skim it first to spot concrete topics (dates, session numbers, task names). If that preview doesn't surface an obvious query, try broad keywords like overview, recent work, or a topic guess — hybrid BM25 + vector retrieval will surface chunks that share any of the terms, and you can iterate from there.
