Your Markdown vault is canonical. DuckDB is the replaceable retrieval cache. Website · PyPI · Obsidian companion · Benchmarks A cairn marks a trail for whoever comes next. agentcairn does that for coding agents: it captures durable context from the tools you use, stores it as inspectable Markdown with provenance, and recalls only the most relevant pieces when another agent needs them. Proof you can inspect The memory is not hidden behind an admin console or a hosted database. The separate agentcairn-obsidian companion reads the same Markdown files as the agents and exposes provenance, currency, importance, supersession, and related: links. A real agentcairn vault in Obsidian. The list is a view over the files—not a second memory store. Dogfood snapshot · 2026-07-15. Across 417 local recalls, the maintainer's vault returned context about 262× smaller than loading the full vault each time—an estimated 136.6M tokens of full-vault context avoided in aggregate. Token counts use approximately four characters per token. This is not billed-token savings, and agentcairn sends no telemetry. Install The shortest path is a first-class plugin. It bundles the MCP server, the memory skill, and the host-specific ambient hooks—no separate agentcairn package install. The plugin launches through uvx , so install uv first if uvx --version is not already available.
