hermes - 💡(How to fix) Fix Feature: Native Canvas Mode for collaborative planning and UI/design workflows

Summary

Hermes should support a native Canvas Mode for persistent visual/structured collaboration during planning and implementation workflows.

Right now, users can approximate this with markdown docs, HTML mockups, and chat threads, but there is no first-class collaborative canvas state that can be iteratively edited and shared across sessions/channels.

Problem

For product/UI/API design work, chat-only interaction creates friction:

• decisions and open questions get buried in chat history,
• rapid iteration across variants is hard to manage,
• external collaborators (e.g., Telegram + other LLMs) need a stable artifact/state instead of message fragments,
• handoff quality suffers when context spans many turns.

Proposed capability

Add a native Canvas Mode with:

1. Persistent canvas artifact per session/topic (versioned).
2. Sectioned structure (e.g., Decisions, Open Questions, Flows, Components, API mapping, Risks).
3. Incremental edit operations (append/update/move/delete blocks), not full rewrite only.
4. Diff + history view (who/what changed and when).
5. Shareable target identity for cross-channel collaboration (stable ID/URL-like handle).
6. Export options (Markdown/HTML/JSON) for repo handoff.
7. Optional visual layer for lightweight wireframe blocks/relationships.

Why this matters

• Reduces context loss in long-running multi-agent/multi-channel projects.
• Improves handoff quality from ideation -> implementation.
• Makes Hermes more competitive for real collaborative planning workflows.
• Directly addresses common user expectations for “canvas-like” interaction in modern AI tooling.

Acceptance criteria (MVP)

• User can create/select a canvas in a session.
• User can update named sections without rewriting entire document.
• Canvas has revision history + diff.
• Canvas can be exported to markdown and JSON.
• Canvas can be referenced from chat via stable identifier.

Nice-to-have (post-MVP)

• Telegram/Discord-friendly canvas commands.
• Multi-user locking/conflict-resolution semantics.
• Light visual node/edge representation.

Happy to help refine the schema/UX if useful.
