What

Adds OpenCode-runtime engagement to the harness's install. The active workflow nudge (.claude/hooks/seed-workflow.sh) is Claude-Code-only; OpenCode does not read .claude/ or run those hooks, so an agent under OpenCode skips the workflow silently.

How

  • New core/skill/opencode/agent-workflow.mjs — OpenCode plugin. Injects the Work-Record seed into the system prompt via experimental.chat.system.transform each turn. The OpenCode analog of seed-workflow.sh; SEED is byte-identical to the hook's CTX (pinned by a parity test). Fail-open (try/catch + output.system guard).
  • Install wiringpackage-skill.sh packages it into dist/agent-workflow/opencode/; bootstrap Phase 4 step 4.3o copies it to the consumer's .opencode/plugins/agent-workflow.mjs (auto-loaded by OpenCode, no opencode.json needed). Summary template + README updated; committed .claude/skills/ mirror regenerated.
  • Testtests/hooks/run.sh asserts SEED↔CTX parity and the fail-open shape; check-install-probe.sh requires the plugin; package drift/manifest cover it for free.

Scope / non-goals

Nudge, not a gate — the CI checker stays the sole enforcer. Plan-gate and reinforce hooks intentionally not ported (no OpenCode ExitPlanMode analog; reinforce is a nudge the CI gate backstops).

Verification

  • bash tests/run-all.sh — all 9 layers green.
  • Redline (final diff): GRAY, no red / boundary-violations / checkpoints → Elevated.
  • Checker: clean (exit 0).
  • Behavioral (manual): uses the identical hook proven by a running OpenCode plugin; a live 'seed reaches the model' run wasn't executable here.

Work Record: .agent-workflow/tasks/opencode-engagement.md.

Summary by CodeRabbit

  • New Features

    • Added OpenCode support through an automatically installed plugin.
    • OpenCode now receives a Work Record reminder in each system prompt.
    • The integration fails open, allowing conversations to continue safely if the reminder cannot be applied.
  • Documentation

    • Updated Quick Start and bootstrap documentation with OpenCode setup and verification details.
    • Packaged installations now include the OpenCode plugin and record it in bootstrap summaries.
  • Bug Fixes

    • Improved plugin installation reliability by creating the required plugin directory automatically.

Adds an OpenCode plugin (core/skill/opencode/agent-workflow.mjs) that injects
the Work-Record seed into the system prompt via experimental.chat.system.transform,
the OpenCode analog of .claude/hooks/seed-workflow.sh. Fail-open; the CI checker
stays the enforcer. Wires it through package-skill.sh, bootstrap Phase 4 (4.3o),
the bootstrap summary, README, and a seed-parity/fail-open test in tests/hooks.

📝 Walkthrough

Walkthrough

This change adds a fail-open OpenCode plugin that injects the Work-Record seed into system prompts. Packaging and bootstrap install the plugin. Documentation, manifests, tests, and work records cover the integration.

Changes

OpenCode engagement support

Layer / File(s) Summary
OpenCode prompt injection and validation
.claude/skills/agent-workflow/opencode/agent-workflow.mjs, core/skill/opencode/agent-workflow.mjs, tests/hooks/run.sh
The plugin appends or initializes the Work-Record seed in system prompts. It ignores invalid output and runtime errors. Tests require non-empty seed values and verify parity.
Packaging and bootstrap installation
scripts/package-skill.sh, core/skill/bootstrap-mode.md, .claude/skills/agent-workflow/bootstrap-mode.md, .claude/skills/agent-workflow/manifest.txt, tests/package/check-install-probe.sh
Packaging includes the plugin. Bootstrap creates .opencode/plugins and copies the plugin to .opencode/plugins/agent-workflow.mjs. Manifests and install probes require the packaged file.
Documentation and work records
README.md, core/templates/bootstrap-summary.md.template, .claude/skills/agent-workflow/templates/bootstrap-summary.md.template, .agent-workflow/tasks/opencode-engagement.md
Documentation describes OpenCode installation and behavior. Bootstrap summaries list the plugin. The work record records assumptions, implementation, and verification evidence.

Estimated code review effort: 2 (Simple) | ~10 minutes

Comment thread core/skill/bootstrap-mode.md Outdated
…strap Phase 4

Addresses CodeRabbit: a fresh consumer repo has no .opencode/ (unlike .claude/,
which Phase 4.0 creates via the skill copy), so the plugin copy could fail.
Phase 4.3o now creates the directory first. Regenerated dist + .claude/skills mirror.

Good catch — fixed in 79c94db. You're right that .opencode/ has no creating step (unlike .claude/, which Phase 4.0 creates via the skill cp -r), so a fresh consumer repo could fail the copy. Phase 4.3o now runs mkdir -p .opencode/plugins first. Source + dist/ + the committed .claude/skills/ mirror all regenerated.
