SOURCE LINK UNAVAILABLE · PROJECT NOTE

OpenContext

The design splits documents into L0, L1, and L2 information layers so an agent can scan summaries before drilling into full text, with session memory retaining useful context.

Design scope

CORE

Three knowledge layers

Controls information density and token use through one-line, structured-summary, and full-text levels.

Retrieval and browsing

Organizes documents with ctx:// paths and combines semantic and keyword search for progressive drill-down.

Memory and integration

The design includes extracting memory from sessions and connecting agent clients through MCP.

Who it is for

Useful for readers studying how agents may browse knowledge by information density and combine retrieval with long-term memory.

Read the boundary first

The former repository is unavailable, so this page is a design note only. It cannot establish that code is installable, runnable, or maintained.

Ways to use it

  1. Study how a long document can expose a one-line summary before structured summary and full text.
  2. Compare semantic and keyword retrieval for proper nouns, code symbols, and natural-language questions.
  3. Separate short context, persistent preferences, and deletable personal information when discussing session memory.

How to review the result

  1. With no accessible source, this page cannot provide install commands, dependency versions, or observed runs.
  2. ctx:// paths, layered knowledge, and memory integration are project design rather than a verified general standard.
  3. A current selection needs comparison with alternatives that remain obtainable, runnable, and maintained.

Current status and evidence

2026-09-23

The former GitHub URL returned 404 on 2026-09-23. The page no longer says that public source is available.

The available evidence is first-party: deployment records, product documentation, and endpoint status at the review time. No independent evaluation was available. Reachability confirms access at that moment, not performance, accuracy, savings, or long-term availability.
