Use Lians financial-grade agent memory - store and recall facts with a bitemporal model so stale revisions never contaminate context. Use whenever an agent needs persistent memory in finance, healthcare, or legal work, or when a task asks "what did we know on/before <date>", needs an audit trail, or must erase a data subject.

From the source SKILL.md

Lians is a memory layer for AI agents built for regulated environments. Unlike a plain vector store, it uses a bitemporal model: every fact carries the business time it became true (event_time) and the system time it was known (valid_from/valid_to). When a new fact supersedes an old one, the old one is excluded from recall automatically - but remains reconstructable for any past date.

What this skill does

Lians is a community-contributed Claude Code skill in the finance-personal sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/lians/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use whenever an agent needs persistent memory in finance, healthcare, or legal work, or when a task asks "what did we know on/before <date>", needs an audit trail, or must erase a data subject.

Who uses this skill

The Lians Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 188,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
