  • Confirm the extracted package contains the expected setup assets.

Install with your agent

Agent handoff

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.

  1. Download the package from Yavira.
  2. Extract it into a folder your agent can access.
  3. Paste one of the prompts below and point your agent at the extracted folder.
New install

I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.

Upgrade existing

I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

Hypabase Memory

Persistent memory for agents. Stores preferences, decisions, facts, and events as a connected knowledge graph. Recalled by who, what, when, or why.

Setup

Add the MCP server to your OpenClaw config (~/.openclaw/openclaw.json): { "mcpServers": { "hypabase-memory": { "command": "uvx", "args": ["--from", "hypabase", "hypabase-memory"], "env": { "HYPABASE_DB_PATH": "hypabase.db" } } } } uvx handles all Python dependencies automatically. Requires uv.

Quick start

Store a memory β€” one verb, roles for the participants: remember(penman='(prefers :subject Alice :object Python :memory_type semantic)') Recall it: recall(entity="Alice") # everything about Alice recall(entity="Alice", action="assign", role="subject") # what Alice assigned recall(entity=["Alice", "Bob"]) # memories involving both recall(mood="planned") # all plans

When to Remember

Store a memory when the user: Makes a decision or states a preference Shares a fact about themselves, their team, or a project Assigns a task or delegates work Describes an event, meeting, or outcome Explains a procedure or workflow

PENMAN Notation

Every memory is a verb with participants in role slots: (verb :role "entity" :role "entity" ...) Examples: (prefers :subject Alice :object Python :memory_type semantic) (assigned :subject Alice :object "billing task" :recipient Bob :instrument Jira :locus Monday :tense past :memory_type episodic) (has :subject "quick sort" :attribute "time complexity" :value "O(n log n)" :memory_type semantic) Multiple atoms in a single call: (deployed :subject Alice :object API :locus Monday :tense past) (reviewed :subject Bob :object API :locus Tuesday :tense past) One action per memory. When a sentence contains multiple actions, decompose into separate atoms. Shared entities link them in the graph. "Alice told Bob to migrate the database": (told :subject Alice :recipient Bob :object "database migration" :tense past) (migrate :subject Bob :object database :mood planned) Any role slot can hold a nested atom: (believes :subject Alice :object (is :subject deadline :value Friday))

Entity Naming

Same string after lowercasing = same entity. Different strings = different entities until consolidate() merges them. Pick one canonical name per entity and reuse it. Use full descriptive names: "machine learning" not "ML", "JavaScript" not "JS". Call consolidate() periodically to merge similar names via semantic similarity.

remember(penman, source?, confidence?)

Store memories as PENMAN atoms. penman (required): One or more PENMAN atoms. source (optional): Provenance source. Default: "memory". confidence (optional): 0.0–1.0. Default: 1.0.

recall(entity?, action?, role?, memory_type?, mood?, negated?, since?, before?, limit?, min_strength?)

Query memories. At least one parameter required. entity: Name or list of names. action: Filter by verb. role: Filter by role (subject/object/instrument/recipient/source/locus/attribute/value). memory_type: episodic / semantic / procedural. mood: actual / planned / uncertain / normative / conditional. negated: true = only negated, false = only positive. since / before: ISO date strings. limit: Max results (default: 10). min_strength: Minimum memory strength threshold.

consolidate(entity?)

Merge similar entities and compress repeated memories.

forget(older_than_days?, min_strength?, entity?)

Expire old or low-strength memories (soft delete).

Roles

Eight roles. Fill in what applies, skip what doesn't.
