Plugin Overview & Capabilities

AI-assisted organization based on the public repository snapshot. The content must be grounded in source evidence and does not replace compatibility or security verification.

source-grounded
Morning Star (mstar-harness) is an agent plugin bundle and workflow engine designed for harness engineering workflows across DeepSeek Harness (DSH) and other agent environments. It couples a TypeScript engine (@mstar-harness/engine) that enforces deterministic workflow gates (phase, dispatch, status, review, and SDD gates) with judgment skills across multiple agent roles like project-manager, dev, and QC specialist.

Key Capabilities

  • Enforces deterministic gates for path, status, lease, dispatch, iteration, and SDD via a TypeScript engine
  • Provides multi-agent role definitions and judgment skills including project-manager, architect, QC trio, and qa-engineer
  • Supports phased iteration workflows with compass locking, autonomous loops, and scoped plan session execution
  • Offers read-only audit and review commands for codebases, PRs, tests, and E2E verifications
  • Integrates local dashboard web UI for read-only tracking of the issue store and execution roadmaps
  • Provides MCP server capabilities exposing canonical workflow commands as MCP tools

Useful For

  • Managing complex multi-phase software engineering tasks with multi-agent coordination inside DeepSeek Harness
  • Enforcing strict automated quality control (QC) and QA acceptance gates before merging pull requests
  • Executing read-only architectural audits and pre-merge pull request reviews across repositories
  • Running autonomous or semi-autonomous development iteration loops with persistent JSON snapshots

Who It Fits

  • Software engineers orchestrating multi-agent development workflows in DeepSeek Harness
  • Technical leads requiring deterministic gate enforcement and structured review cycles for LLM agents
  • Developers looking for structured SDD (subagent-driven development) and iteration compass management

Documented Limitations

  • CLI binary entrypoints require Bun >= 1.4.0 or Node.js >= 24.18.0
  • The Cordis YAML MCP launch configuration for DSH is documented as follow-up work and reports unavailable in doctor checks
  • The short CLI alias 'mstar' shares name with an unrelated npm package, requiring the full 'mstar-harness' invocation when conflicts occur

DSH Compatibility

Version-specific runtime evidence collected by DSH Plugin. A missing result means we have not tested that combination yet.
