Ecosystem review

Initial review: 2026-08-17. Refreshed: 2026-08-21 against Harness next (0.1.0-rc.8) and current public ecosystem indexes.

Question

Does the Harness ecosystem already have a tool that automatically finds a 1-minimal failure-inducing set of profile plugins, including interaction sets where every member passes alone?

Sources and method

The review covered:

• The official DeepSeek Harness repository and its current plugin packaging/profile documentation.
• The community awesome-dsh-plugin catalog, searched for doctor, guard, repair, repro, conflict, bisect, delta debugging, minimal failing set, and Chinese equivalents.
• GitHub and npm exact-name searches for dsh-plugin-reducer, dsh-plugin-bisect, dsh-ddmin, and related terms.
• Public descriptions and source trees of the closest projects below.

No reviewed project matched the exact job, and the refreshed official source still contains no ddmin/minimal-failing-plugin implementation. This remains a time-bounded search result, not a claim that an unknown or later project cannot exist.

The community catalog now indexes the repository but correctly excludes it from its downstream installable-plugin market: this project intentionally remains an external CLI so it can work when the plugin tree cannot load. The repository therefore does not use the dsh-plugin GitHub topic and should be described as Harness companion tooling rather than as a dsh.bundle package.

Closest existing work

dsh-startup-guard

dsh-startup-guard focuses on preflight checks, snapshots, repair, smoke tests, and quarantine. Its product outcome is a recoverable/bootable profile. The reducer starts after there is a stable failure and searches for the minimal reproducing bundle set.

dsh-boot-guard

dsh-boot-guard provides a loader-independent rescue route and manual plugin skipping. That is valuable when the normal plugin system cannot start. It does not perform automated subset or complement search.

dsh-repro

dsh-repro exports secret-scrubbed session context, failed commands, and git diff information. It reduces the cost of communicating a coding/session reproduction; it does not minimize the profile's active bundle set.

dsh-builtin-toggles

dsh-builtin-toggles inspects and toggles built-in capabilities and exposes compatibility/provenance information. The reducer instead treats installation bundles as fixed and searches user-installed bundle interactions.

Decision boundary

The project proceeds only within this gap:

• external even when the plugin tree is broken;
• automatic subset/complement search;
• explicit support for interaction failures;
• no repair, quarantine, marketplace, or plugin-management features;
• a shareable, scrubbed evidence report.

If an established project adds the same job with equivalent safety and interaction handling, the preferred response is collaboration or upstreaming, not parallel feature competition.
