memorysaver Design
Interactive feature design on the integration branch ($BASE — resolve per /aep-git-ref "Resolving $BASE"). Explore the problem, propose a solution, review the design, and commit artifacts — all in conversation with the user.
Where this fits:
/aep-onboard → /aep-scaffold → [ /aep-design → /aep-launch → /aep-build → /aep-wrap ]
▲ you are here
Session: Main session, interactive with user Input: Feature idea or user request (optionally informed by product context) Output: OpenSpec change committed to the integration branch (proposal, design, specs, tasks)
Operating Mode
Auto-detect at startup:
ls product-context.yaml 2>/dev/null
- Standalone (no
product-context.yaml) — the feature lifecycle runs independently; proceed to Prerequisites. - Product-cycle (has
product-context.yaml) — the feature is a story in/aep-envision→/aep-map→/aep-dispatch→/aep-design. Read references/modes.md for how a dispatched story's context (acceptance criteria, interface obligations, existing change) loads before the phases.
Prerequisites
Two one-line checks — /aep-onboard installs missing tools, /aep-scaffold installs missing OpenSpec skills:
which git openspec >/dev/null 2>&1 && { which gh >/dev/null 2>&1 || which glab >/dev/null 2>&1; } || echo "MISSING cli tool → run /aep-onboard"
ls .claude/skills/openspec-{explore,propose,apply-change,archive-change}/SKILL.md >/dev/null 2>&1 || echo "MISSING openspec skill → run /aep-scaffold"
Workflow Mode Selection
Pick a workflow mode — full or light — before designing. It governs Phase 3 below and carries through to /aep-launch and /aep-build. Read references/workflow-modes.md for the two modes, the selection criteria, and how the choice is recorded so launch and build honor it.
Phase 1: OpenSpec Explore
/opsx:explore
Clarify requirements and scope with the user, investigate the codebase for relevant patterns, identify risks and unknowns, and create a docs/ architecture note if the feature warrants it.
Postcondition: requirements, scope, and risks are captured in the change directory (openspec/changes/<change-name>/).
Phase 2: OpenSpec Propose
/opsx:propose
Generates the full OpenSpec change: proposal.md (what/why), design.md (how, key decisions, risks), specs/**/*.md (requirements and scenarios), tasks.md (implementation checklist). When a story was dispatched, the change already exists — /opsx:propose refines it.
Postcondition: openspec/changes/<change-name>/proposal.md exists (alongside design.md, specs/, tasks.md).
Phase 3: Design Review
Review scope — architecture, interfaces, task decomposition — from non-functional angles:
- Security — auth gaps, injection surfaces, data exposure?
- Performance — N+1 queries, large payloads, blocking operations?
- Existing patterns — does it follow codebase conventions?
- Edge cases — concurrency, race conditions, failure modes?
Update the OpenSpec change files directly if adjustments are needed.
Light mode: skip Phase 3 entirely.
Postcondition: the user has approved the design, recorded in proposal.md (an approval note or checked box).
Commit to the Integration Branch
Commit the change directory and any architecture docs to $BASE as a control-plane commit — per /aep-git-ref "Control-Plane Commits" (resolve $BASE per /aep-git-ref "Resolving $BASE"). Stage explicitly with git add openspec/changes/<change-name>/ docs/ and message feat: add <change-name> architecture doc and OpenSpec change. This ensures the workspace has all artifacts when it is created from $BASE.
Postcondition: the change directory is committed and pushed to $BASE.
Next Step
Design is complete. Proceed to /aep-launch, which spawns an autonomous workspace session to implement the feature.
