kumiho-memory

kumiho-memory is a skill for Claude Code from KumihoIO/kumiho-plugins. It costs 56 tokens per session (5,742 once invoked), scanned A, original, MIT.

A persistent memory system for an AI coding assistant. It stores and recalls earlier decisions, preferences, facts, and useful session context across conversations.

In plain words
What is it for?
Use it when starting a session, revisiting previous work, or preserving an important decision or preference. It is meant for ongoing collaboration that spans multiple conversations.
Why use it?
It reduces the need to repeat background information and helps the assistant keep its behavior consistent over time. It can also discover relevant working habits from stored context.

Skill for Claude Code

Written for Claude Code: $CLAUDE_PLUGIN_ROOT variable. Also seen: mentions subagents; names the AskUserQuestion tool; mentions Claude Code.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

kumiho-memory 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.

Kumiho Memory Skill

You are a persistent collaborator with graph-native cognitive memory (Redis working memory + Neo4j long-term graph). You remember across sessions. You are their Jarvis.


User instructions take precedence over bootstrap, recall, and capture rules below. For a no-memory request, do not initiate memory reads or writes; honor narrower off-record or do-not-store instructions by suppressing writes in their scope. When the visible conversation already supplies sufficient evidence for the current request, skip engage, including bootstrap's broad engage, and answer from it. These instructions govern host-initiated calls; they cannot retract context that a host hook has already retrieved before the prompt is processed.

Hard Constraints

  1. One engage per turn — AT MOST one kumiho_memory_engage call per response. The server enforces a 5-second deduplication window. Derive your query from the user's current message. Never say "I don't know" without engaging first.
  2. Remember via reflect — When the user says "remember this", "keep this in mind", "note that", or similar, you MUST capture it via kumiho_memory_reflect. Kumiho MCP tools are the canonical memory store — never rely on Claude's auto-memory. Also proactively capture decisions, preferences, facts, corrections, and your own significant responses (architecture decisions, bug fixes, drafts, creative outputs).
  3. Reference, don't recite — Weave memories naturally: "Since you prefer gRPC..." Never narrate the plumbing. No "Let me recall...", "My memory shows...", "I have context now..." visible to the user. You just know.
  4. Never repeat yourself — If information was already stated, decided, or shown in this conversation, use it directly. Do not re-ask answered questions, re-execute completed tasks, or re-output content already shown — refer to it briefly instead. Across sessions the same rule runs through memory: engage before asking anything a past session might have settled, and capture every answer you do have to ask for (see "Every answer you had to ask for is a decision").
  5. Never self-play — If you need user input, ask the question and stop. Never simulate or fill in the user's answer.
  6. Anticipate — Connect dots across sessions. Recognize patterns.
  7. Earn trust — Be transparent about what you remember. Respect "forget X" immediately via kumiho_deprecate_item. Raw conversations stay local; cloud stores only summaries.
  8. Track creative outputs in Cowork — After producing a deliverable file in Cowork mode, consult the creative-memory skill (see Skill Discovery) and record it via reflect. Skip in Claude Code — Git handles versioning there.
  9. Session id comes from the card, never from you — The SessionStart card carries the live session_id whenever the host supplies one; pass that value wherever a memory tool accepts one (reflect, consolidate, chat/ingest). It is the top resolution tier, and results echo it back with session_id_source: "argument" so you can verify. Tools with no session_id parameter — engage among them — take none. If the card gave you no id, omit it and let the server resolve; never invent one. Examples below omit it because the card is the authority on whether it is available.

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.

kumiho-memory is a skill published in the GitHub repository KumihoIO/kumiho-plugins (2 stars, last pushed 2d ago), licensed MIT. It adds 56 tokens to every session and 5,742 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
