feat(opencode): proactively delegate cost-effective work

[xnoto]

Summary

• Update all nine full-capability primary-agent prompts to proactively delegate bounded, independently verifiable research, extraction, review, and implementation work when a capable lower-cost worker can reduce total cost or latency.
• Preserve primary ownership of interpretation, architecture, safety, cross-repository impact, mutation authorization, and final conclusions; require scoped delegation prompts, independent parallelism, and verification of material findings.
• Document the policy in the agent-instruction architecture and bump the immutable opencode-server chart version from 0.1.62 to 0.1.63.

Fixes #

None — owner-approved policy adjustment.

Type of change

• Bug fix
• Feature / enhancement
• Documentation
• Infrastructure (OpenTofu root or module)
• GitOps desired state (manifests, kustomize, charts, SOPS/KSOPS secrets)
• Container image
• CI / reusable workflow
• Refactor / cleanup
• Breaking change

Validation

• Required pull-request checks pass — workflow run 33919957833 passed repository hygiene, Helm validation, changed-chart detection, and package opencode-server on rerun.
• Generated or centrally distributed files were regenerated by their owning automation, not hand-edited — none exist among the changed chart inputs.
• Reviewed both branch commits and the complete 11-file prompt, architecture, and version diff. No local Helm, OpenTofu, or repository checks were run or claimed; CI is the validation authority.

Impact and rollout

Producer changed: makeitworkcloud/charts owns the packaged OpenCode prompts and non-secret configuration. This authored and validated change updates the nine primary-agent definitions, their architecture document, and chart version 0.1.63; it does not change subagent definitions, default_agent, images, secrets, or GitOps source.

Consumer unchanged until merge: after an explicitly approved merge, the charts main workflow can publish immutable chart 0.1.63 and automatically create or update the separate makeitworkcloud/kustomize-cluster version-pin pull request. That generated desired-state PR, its merge, Argo CD reconciliation, workload health, and representative agent behavior remain separate, unverified stages.

Rollback: select the prior immutable chart version through the canonical kustomize-cluster Application workflow; never overwrite an OCI version.

Safety and secrets

• Contains no plaintext secrets, decrypted SOPS values, state files, kubeconfigs, tokens, or private endpoints — the diff was manually reviewed. GitHub Advanced Security secret scanning is unavailable for this repository.
• No local OpenTofu init/plan/apply/destroy/import/state operations were run or claimed — plans come from pull-request checks.
• Breaking or irreversible effects are described above with rollback notes — no live change is made by this pull request.

AI-assisted change: an OpenCode agent materially produced this prompt-policy and documentation update; reviewers should verify the primary-decision boundaries and all nine role-local prompt copies.
