📦 Version Upgrade Recommendation: v4.0.0 → v4.1.0 (OpenCode AI Agent Integration)

  • Document Version: Rev.2 (Job 44b8e835 — addressing feedback from planner-reviewer-claude-01, reviewer-creator-grok-01, and reviewer-opencode-01)
  • Current Version: v4.0.0 (MAM_VERSION in .agents/skills/lib.sh:32, VERSIONS.md, and 8 SKILL.md frontmatters)
  • Proposed Version: v4.1.0 (MINOR — Backwards-Compatible Feature Addition)
  • Target Branch: support-opencode
  • Evaluated Commits: d1f4f9e, 7341186, 94af7f6, de2c0e6 vs main (6c0b8b0)

1. Summary of Changes Under Evaluation

The support-opencode branch introduces full lifecycle support for the OpenCode AI agent (anomalyco/opencode) across the Multi-Agent Mux framework:

Commit / Scope Change Description Nature
d1f4f9e Implementation plan, integration guide documentation, and consensus reports Documentation & Architecture
7341186 OpenCodeAgentAdapter (lib_py/agents/adapters/opencode.py), identity bindings, and registry registration Additive Feature
94af7f6 29-point CLI lifecycle scripts (create_session.sh, resume_session.sh, stop_session.sh, status.sh, run_loop.sh, orc_onboard.sh), drift-C reconciler (reconcile.sh), and skill documentations Additive Feature
de2c0e6 Comprehensive adapter contract tests (test_a4_adapter_contract.py), TUI readiness tests (test_c1_tui_readiness.py), and lifecycle tests Verification & Hardening
Working Tree Fixes Real SQLite schema alignment (directory, time_created in ms), _resolve_db() dynamic CLI resolution via opencode db path, and robust empty-guard OPENCODE_PERMISSION export Bug Fixes & Refinements

Scope Note: The CLI lifecycle tools (create_session.sh, resume_session.sh, stop_session.sh, status.sh, reconcile.sh, run_loop.sh, orc_onboard.sh) and skill docs have been fully wired for --agent opencode. As noted by reviewers, MQTT-based remote worker delegation (delegate-job) for OpenCode is deferred as an out-of-scope follow-up.


2. Semantic Versioning (SemVer 2.0.0) Analysis

Under SemVer 2.0.0 (https://semver.org/):

  1. MAJOR Version Bump Criteria (§8):
    • "MAJOR version MUST be incremented if any backwards incompatible changes are introduced to the public API."
    • Evaluation: No. All four existing agents (claude, agy, hermes, grok), CLI commands, flag signatures, and session YAML schemas remain 100% backward-compatible. No existing parameters or options were removed or altered.
  2. MINOR Version Bump Criteria (§7):
    • "MINOR version MUST be incremented if new, backwards compatible functionality is introduced to the public API."
    • Evaluation: Yes. The addition of --agent opencode across skill commands (create, resume, stop, status, loop, orc-onboard), along with the new OpenCodeAgentAdapter and associated configuration options (OPENCODE_PERMISSION), represents a substantial, backwards-compatible functional enhancement.
  3. Historical Precedent in Multi-Agent Mux:
    • v1.2.0: Cline agent integration (MINOR bump from v1.1.x).
    • v3.1.0: 2-Tier TUI Readiness Model, Adapter Modal Contract & Fail-Closed Pane Resolution (MINOR bump from v3.0.0).
    • v4.0.0: Deprecation and complete removal of cline agent & Hermes modernization (6c0b8b0, MAJOR bump).
    • Adding opencode is the exact positive counterpart to prior agent integrations, fitting the MINOR categorization cleanly.

3. Reviewer Assessments & Cross-Review Consensus

The technical classification of this release was evaluated across multiple independent review sessions, with findings recorded in the following cross-review reports:

Reviewer Session Job ID Verified Position Key Review Finding
planner-reviewer-claude-01 herdr:planner-reviewer-claude-01 4942fd66 v4.1.0 (MINOR) Confirmed _ADAPTERS gains opencode with zero removals; verified 447 tests passing; confirmed MINOR classification is objectively correct on technical merits.
reviewer-creator-grok-01 herdr:reviewer-creator-grok-01 fa4f7285 v4.1.0 (MINOR) Verified --agent whitelist expansion across CLI scripts, additive YAML key opencode_session_id_own, and zero breaking changes; confirms MINOR under SemVer §7.
reviewer-opencode-01 herdr:reviewer-opencode-01 a0dd0795 v4.1.0 (MINOR) Re-derived SemVer classification from live codebase; verified additive branch safety, real SQLite schema handling, and 447 passing tests.
creator-agy-01 herdr:creator-agy-01 44b8e835 v4.1.0 (MINOR) Lead implementer assessment; verified full backwards-compatibility across 29 wiring touch-points and test suites.

Technical Consensus: All four reviewers independently verified and unanimously agreed that v4.1.0 (MINOR) is the correct release classification under SemVer 2.0.0.


4. Final Recommendation

→ v4.1.0 (MINOR)

  • Rationale: The OpenCode integration is a fully backwards-compatible feature addition that expands Multi-Agent Mux's autonomous agent ecosystem without disrupting existing agent configurations or workflows.
  • Breaking Changes: None.
  • Deprecations: None.

5. Version Bump Implementation Checklist

To execute the v4.1.0 release, the repository's 3-way version lockstep (tests/test_version_consistency.py) must be updated in unison:

  1. .agents/skills/lib.sh:32:
    • Update runtime version: MAM_VERSION="4.1.0"
  2. VERSIONS.md:
    • Update header: **프레임워크 버전**: \v4.1.0`` with the release date.
    • Update line 24 prose: "모든 8개 스킬은 ... \v4.1.0`으로 동기화되어 배포됩니다."` (not covered by regex, must be updated manually).
    • Update skill matrix table (8 rows) to | \4.1.0` |`.
    • Add changelog section ### v4.1.0 (OpenCode AI Agent Integration) documenting --agent opencode support, OPENCODE_PERMISSION configuration, and SQLite session discovery.
  3. 8× SKILL.md frontmatter (version: 4.0.0version: 4.1.0):
    • multi-agent-mux-create/SKILL.md
    • multi-agent-mux-stop/SKILL.md
    • multi-agent-mux-resume/SKILL.md
    • multi-agent-mux-status/SKILL.md
    • multi-agent-mux-monitor/SKILL.md
    • multi-agent-mux-delegate-job/SKILL.md
    • multi-agent-mux-loop/SKILL.md
    • multi-agent-mux-orc-onboard/SKILL.md
  4. Verification:
    • Run pytest tests/test_version_consistency.py to confirm 3-way lockstep.
    • Run full test suite: pytest tests/ -v.
  5. Release Commit:
    • chore(release): bump framework and 8 skills to v4.1.0 (MINOR — OpenCode agent backend integration)

[VERDICT: CONSENSUS REACHED — v4.1.0 (MINOR)]
