Agents, context & control

A useful answer becomes easier to assess when the reader can follow it back to the underlying material.

People need explicit limits or inspectable records around what an agent does.

A human review step becomes part of the product workflow.

Some builders make local processing, local storage or self-hosting a defining part of the product.

APIs and MCP make infrastructure, data and actions callable.

Messaging and voice interfaces connect to operational work.

Knowledge and corrected working methods become material for later AI tasks.

The starting point: Founder networking threads, quote posts and related posts, followed by project websites. The September 18 research reviewed 854 records: 851 unique projects and three duplicates.
What we could learn: 485 projects had enough evidence for the offering, audience and approach; 177 had a meaningful description with gaps; 189 lacked enough information. 440 projects fit the 70 recurring ideas in this edition.
What a wave means: A shared task, audience need or approach, checked against each project’s sources. It describes a pattern in this catalogue, not measured market growth. Some projects fit several waves; others have a distinct idea or need more information.
Follow the evidence: Open a wave for its criteria and source excerpts, then a project for the original sources and its builders. Counts above reflect the current published catalogue; the downloadable map records the research edition.
