[BUG]: customize-opencode skill has wrong/missing command docs

[Grantmartin2002]

Description

The built-in customize-opencode skill has a few problems around commands:

• The command example uses prompt, but the schema wants template. If you follow it, opencode won't start (ConfigInvalidError: Missing key ... ["template"]).
• It never mentions that commands can live as .opencode/command/<name>.md files, so the agent just inlines everything into opencode.json.
• The skill's own description doesn't list commands, so it sometimes doesn't load when you ask for a slash command.

OpenCode version

v1.17.7 (also on dev)

Steps to reproduce

1. Open a project with no opencode.json.
2. Ask the agent to add a /hello command.
3. It follows the skill and writes prompt instead of template.
4. Restart opencode, startup fails with ConfigInvalidError: Missing key at ["command"]["hello"]["template"].

This issue might be related to an existing open issue. Please check:

• [BUG]: Built-in customize-opencode skill is outdated — missing tools field, MCP permission handling, and * catch-all #31982: Also reports the built-in customize-opencode skill as outdated/inaccurate (different specific fields, but the same skill file)

These are distinct bugs, but you may want to coordinate with the reporter of #31982 since both issues affect the same skill content.
