Adds a blog post introducing Cosift, the open-source, free index that agents fill in as they browse.

What it covers

  • The problem: agents fetch and re-read the same web pages on every run and throw the work away.
  • The model: a collaborative index where an agent that fetches a page also indexes it, so every agent after it retrieves instead of refetching; 15M contributions already.
  • Free if your agent contributes: the credit scheme (contribute to earn, retrieve to spend, idempotent by content hash), or self-host.
  • Its roots in Pilot: ~400B agent exchanges and 500+ data-serving agents; Cosift as a data-service agent that accepts contributions.
  • How an agent uses it over MCP (cosift-install, cosift.help latency classes), what runs underneath, and how contributions are verified before anything is indexed.

Conventions

  • Same structure and voice as the two recent posts by Artemii Amelin; author={{ name: 'Artemii Amelin', type: 'Person' }}.
  • 1200×630 SVG banner in the site's existing banner style, and an entry in src/data/blogPosts.json.
  • npm run build, npm run check:plain, and npm run check:site all pass with no problems on the new page.

Add a blog post introducing Cosift, the open-source, free index that agents
fill in as they browse: fetch a page once, index it, and every other agent
retrieves it instead of refetching. Covers the collaborative-memory model,
the contribute-to-use credit scheme, its roots in Pilot's agent exchanges,
how an agent uses it over MCP, what runs underneath, and how contributions
are verified before indexing.

Follows the existing post conventions: authored as Artemii Amelin, a
1200x630 SVG banner in the site's style, and an entry in blogPosts.json.
npm run check:plain and npm run check:site both pass.
