Skill-driven harness/loop engineering workflow agent plugin.
Install
# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)
dsh plugin --profile web add github:btspoony/mstar-harness
GitHub-sourced plugins run build scripts on your machine at install time. Only install sources you trust, and pin a commit (github:owner/repo#sha).

Morning Star is an Agent Plugin for harness engineering workflows: a TypeScript Harness Workflow Engine (@mstar-harness/engine) enforces deterministic workflow gates, while mstar-* judgment skills drive multi-agent code delivery.
- Deterministic gates, enforced by a TS engine — path/status/lease/dispatch/sdd/iteration/lint gates run in
@mstar-harness/engine, not as prompt suggestions - Judgment stays in
mstar-*skills — skills remain the single source of truth (SSOT) for roles, gates, and workflow judgment - One engine across hosts — the same engine + skills power dsh (DeepSeek Harness), omp, OpenCode, Cursor, Kimi Code, ZCode, and Codex
- Agent Plugin packaging — one-command install; portable across any Agent Plugins v1.0.0 client
- Recommended host (best → usable): dsh = omp ≥ OpenCode ≥ Cursor > Kimi = ZCode > Codex

Release notes: CHANGELOG.md / CHANGELOG_CN.md.
Install
dsh installs through its own plugin manager — not the CLI.
npx @mstar-harness/cli inithas no dsh target (it covers omp / OpenCode / Cursor / Kimi / ZCode / Codex only). On dsh (DeepSeek Harness), install the profile bundle with the host's own command:dsh plugin --profile web add @mstar-harness/dsh.
npx @mstar-harness/cli init
# or: bunx @mstar-harness/cli init
| Host | Command |
|---|---|
| dsh (DeepSeek Harness) | dsh plugin --profile web add @mstar-harness/dsh |
| omp | npx @mstar-harness/cli init --target omp (links ~/.mstar/harness) or omp plugin install github:btspoony/mstar-harness |
| OpenCode | npx @mstar-harness/cli init --target opencode |
| Cursor | npx @mstar-harness/cli init --target cursor |
| Kimi | Kimi TUI: /plugins install https://github.com/btspoony/mstar-harness → /plugins reload |
| ZCode | npx @mstar-harness/cli init --target zcode then install morning-star-harness in ZCode → Settings → Plugin Management |
| Codex | npx @mstar-harness/cli init --target codex then codex plugin add morning-star-harness --marketplace personal |
| Generic (Agent Plugins v1) | point any Agent Plugins v1.0.0 conformant client at this repo root (plugin.json + skills/ are the portable package) |
The repo ships a portable Agent Plugins v1.0.0 manifest (plugin.json) at its root; skills/ is the Agent Skills component. Verify with npx @mstar-harness/cli plugin validate.
Verify: npx @mstar-harness/cli doctor --target <opencode\|cursor\|codex\|zcode\|omp>.
Manual install / path layout: INSTALL.md. CLI flags: docs/cli.md.
Reload the host after install (OpenCode restart / Cursor Developer: Reload Window / reopen Codex / Kimi /plugins reload or /new / ZCode reload plugin / omp new session or /reload-plugins if available).
Use
Three entry shapes: without iteration (single plan / hotfix), with iteration (multi-plan Phase 1–5), or codebase audit (discover what to do).
General (without iteration)
Enter PM, then run the per-plan cycle: Prepare → Execute → QC → QA gate → Done.
| Host | Enter PM |
|---|---|
| dsh (DeepSeek Harness) | pm skill (via the mstar skill provider; no auto-load) |
| omp | /skill:pm each session (no auto-load) |
| OpenCode | agent.project-manager (agents/project-manager.md) |
| Cursor | /pm |
| Kimi | session auto-loads pm; or /skill:pm |
| ZCode | /morning-star-harness:pm each session (no auto-load) |
| Codex | /pm |
Iteration
| Path | When |
|---|---|
/iteration-start |
Phase 1 (interactive grill-me) then auto-continues Phase 2→5; pause to stop after Phase 1 |
/iteration-drive |
Resume Phase 2→5 on an already-locked iteration |
/iteration-loop |
Full Phase 1→5 autonomous (no grill-me; optional direction, scale S|M|L|XL) |
Codebase audit
| Path | When |
|---|---|
/codebase-audit |
Survey a repo read-only → prioritized, self-contained improvement plans in {PLAN_DIR}/audit-<date>/ |
Read-only advisory — never edits source. Output feeds iteration-start Research or normal Prepare → Execute. Effort levels: quick / standard (default) / deep; category focus (security, perf, tests, …) or branch / next variants. SSOT → mstar-audit.
Command loading
| Host | How commands load |
|---|---|
| dsh (DeepSeek Harness) | /iteration-start · /iteration-drive · /iteration-loop · /codebase-audit (bundled harness-commands/ via ctx.commands) |
| omp | /iteration-start · /iteration-drive · /iteration-loop · /codebase-audit (filename commands from plugin commands/) |
| OpenCode / Cursor | Bundled from commands/ (OpenCode: plugin harness-commands/) |
| Kimi / ZCode | /morning-star-harness:iteration-start · :codebase-audit (etc.) via plugin manifest |
| Codex project | .agents/skills/<name>/SKILL.md (CLI symlinks from commands/) |
| Codex global | Project-scoped commands not installed — use --scope project |
Phase 2 defaults: per-plan worktree + lease, Findings cleanup: zero-residual. Override only with explicit Worktree mode: waived / Findings cleanup: allow-residual. SSOT → mstar-iteration, mstar-branch-worktree, mstar-plan-artifacts.
Project knowledge bootstrap: mstar-compound-refresh → references/project-knowledge-bootstrap.md.

Consumer plans default to .mstar/. Process artifacts (plans/, iterations/, status.json, sdd/, …) are gitignored; tracked results: {HARNESS_DIR}/AGENTS.md, knowledge/, specs/. Specs resolve .mstar/specs/ → docs/specs/ → repo-root specs/. Details → mstar-plan-conventions.
