metadata:
  instruction_budget: "8"
  framework_dependency: "mycelium"
  framework_dependency_note: "This skill is designed to run within the Mycelium framework (https://github.com/haabe/mycelium). Standalone use will skip the canvas state, theory gates, and harness behavior the skill assumes. Install: /plugin install mycelium@haabe-mycelium."

Canvas Sync

When to Use

  • Starting a new session (pull latest canvas)
  • Ending a session (commit canvas changes)
  • After team discussion that changes product direction
  • When canvas conflicts arise from parallel work

Workflow

Pull Latest

git pull origin main

Then run `/mycelium:diamond-assess` to see what changed.

Commit Changes

git add .claude/canvas/ .claude/diamonds/ .claude/harness/decision-log.md .claude/memory/
git commit -m "canvas: [brief description of what changed and why]"

Conflict Resolution

  • Different canvas files: auto-merges (no conflict)
  • Same file, different sections: usually auto-merges
  • Same field conflicting: the person with more evidence wins — a *manual* resolution heuristic for the team, not an automated merge. No tooling evaluates evidence weight; `Gated by:` a `/canvas-merge` procedure (read both versions, compare provenance depth on overlapping entries, recommend) — not yet built.
  • When uncertain: discuss as team, log decision

GitOps Principle

The canvas system IS GitOps for product knowledge — git is the single source of truth, changes are declarative (YAML), and updates flow through version control with review. For infrastructure GitOps (ArgoCD, Flux), see JiT tooling detection for Kubernetes/infrastructure-as-code projects.

Ships withmycelium

Mycelium won't make your idea good. It keeps you and your agent honest about whether it is, from first idea to market. Built on Claude Code, where the gates are structural. The files and skills port to opencode, Codex and Cursor. Outcome over output.
