CONFIG_DIRS uses singular names but opencode creates plural dirs (agent/ vs agents/)

[mex7xx]

Bug

opencode-synced v0.9.0 hardcodes singular directory names in CONFIG_DIRS, but opencode creates and uses plural directory names. This causes the sync to silently skip directories that contain user content.

Evidence

Source (src/sync/paths.ts:54)

const CONFIG_DIRS = ['agent', 'command', 'mode', 'tool', 'themes', 'plugin'];

Actual opencode directory layout

~/.config/opencode/
├── agent/        ← empty (synced, but nothing to sync)
├── agents/       ← has content (NOT synced) ← BUG
├── command/      ← doesn't exist
├── commands/     ← has content (NOT synced) ← BUG
├── plugin/       ← doesn't exist
├── plugins/      ← has content (NOT synced) ← BUG
├── skills/       ← has content (NOT synced in v0.9.0)

Observed behavior

When running opencode_sync push with default settings, the contents of agents/, commands/, plugins/, and skills/ are silently skipped. Only the empty singular dirs (agent/) are synced.

Impact

Users lose their subagents, commands, and plugins on sync because the tool looks in the wrong directory. This is a silent data loss scenario — there's no warning or error.

Workaround

Add the plural dirs manually via extraConfigPaths:

{
  "extraConfigPaths": [
    "~/.config/opencode/agents",
    "~/.config/opencode/commands",
    "~/.config/opencode/plugins",
    "~/.config/opencode/skills"
  ]
}

Expected fix

Either:

1. Add plural variants to CONFIG_DIRS: ['agent', 'agents', 'command', 'commands', ...]
2. Replace singular with plural to match what opencode actually creates
3. Check both singular and plural and sync whichever exists

Environment

• opencode-synced: v0.9.0 (latest release)
• opencode: 1.18.3
• OS: macOS

Note: The main branch already adds skills/ and ~/.agents/ sync (gated by includeOpencodeSkills/includeAgentsDir), but the singular/plural mismatch for agent/commands/plugins persists and no release includes these fixes yet.
