How to regenerate artifacts after modifying upstream dependencies?

[liangfengmic]

Description

I'm trying to understand the "Fluid" workflow philosophy in OpenSpec 1.0. The documentation states:

"Natural—update any artifact anytime" (https://github.com/Fission-AI/OpenSpec/blob/main/docs/migration-guide.md#whats-changing)

"During implementation, if you discover the design needs adjustment, just update the artifact and continue." (https://github.com/Fission-AI/OpenSpec/blob/main/docs/getting-started.md)

However, I'm encountering a workflow gap:

Scenario:

1. Run /opsx:ff to create all artifacts (proposal → specs → design → tasks)
2. During implementation, discover that design.md needs significant changes
3. Manually edit design.md
4. Now tasks.md is stale and based on the old design

Problem:

• /opsx:continue only creates the next ready artifact, not regenerate existing ones
• No command to regenerate tasks.md based on updated design.md
• Only workaround: manually delete tasks.md and run /opsx:continue again

Question:
I found a proposal for this exact issue at openspec/changes/add-artifact-regeneration-support/proposal.md in the repo, but it appears unimplemented (only proposal.md exists, no design/specs/tasks).

1. Is artifact regeneration support planned for a future release?
2. Is there a recommended workaround besides manual deletion?
3. Without this feature, how is the 1.0 workflow fundamentally different from the legacy version regarding artifact updates?

Any clarification would be greatly appreciated!

I'm also interested to know how to update task based on updated specs

I think we should interact with AI in this case to provide more content and intent, example:

You: I'm implementing add-dark-mode but discovered the design approach
won't work with our current component structure. Need to revise design.md

AI: Let me update design.md based on what you've learned...
[Updates design.md with new approach]

Updated design.md to reflect:
- Component structure constraints
- Alternative implementation strategy

Should I update tasks.md to match?

You: Yes

AI: ✓ Updated tasks.md
Ready to continue with /opsx:apply
