v1.15.13: bootstrap fails (HTTP 500) when config contains unsupported skills #30825

Problem

After updating to OpenCode Desktop v1.15.13 on Windows, the app fails during bootstrap when ~/.config/opencode/opencode.jsonc contains unsupported entries in skills.

Observed errors:

• Failed to load sessions
• Failed to finish bootstrap instance
• Unexpected server error / HTTP 500

Impact:

• Sessions do not load
• Models do not appear in the UI

Root Cause (isolated)

opencode.jsonc had unsupported skills values (example: ui-ux-pro-max, ui-styling, design-system, etc.).
This causes an internal sidecar/bootstrap failure in v1.15.13.

Repro / Isolation

1. Keep unsupported skills in ~/.config/opencode/opencode.jsonc -> app returns bootstrap 500 errors.
2. Disable/remove ~/.config/opencode entirely -> app starts normally.
3. Restore file with unsupported skills -> error returns.
4. Use minimal config (schema only) -> issue disappears.

Workaround

Use a minimal safe config:

{
  "$schema": "https://opencode.ai/config.json"
}

Then restart OpenCode.

Suggested Fix

Please treat unknown/unsupported skills as a warning and ignore them, instead of failing bootstrap with HTTP 500.
