Architecture Decision Workflow

Purpose

Draft an architecture decision with context, options, selected direction, consequences, risks, and verification implications.

Inputs

• AGENTS.md
• .codex/studio.json
• .codex/workflows/architecture-decision.md
• design/gdd.md

Role

Technical Director (technical-director) owns this workflow.

Taxonomy

Category: design-architecture CCGS adaptation coverage:

• architecture decision records
• technical tradeoff capture

CLI aliases:

• architecture-decision

Outputs

• Technical direction
• Architecture tradeoffs
• Risk and gate summary

Validation

• Trade-offs are explicit
• Validation gate is named
• Architecture decision is bounded

Phase Gates

• Confirm project state, owner role, write policy, and selected context.
• Name acceptance criteria before implementation or review work.
• Do not advance to handoff until evidence is recorded or a blocker is explicit.

Required Artifacts

• Summary of the workflow result.
• Files, assets, tasks, or docs changed or proposed.
• Verification evidence and unresolved risks.

Context Contract

• Load AGENTS.md, .codex/studio.json, this workflow, the primary agent, linked skills, and only task-relevant project files.
• Avoid broad context unless the user explicitly approves it.

Output Contract

• Decision or change summary.
• Step-by-step work performed or planned.
• Evidence, blockers, warnings, and next owner.

Stop Conditions

• Required project state, approval, target files, or verification path is missing.
• The task crosses into another role without an explicit handoff.
• The workflow would require generated prompt mirrors or hidden automation.

Handoff

Report changed files, validation evidence, residual risks, and the next owner only when ownership changes.
