Adds the final 7 Claude Code command definitions to the OpenCode guardrails profile, bringing command parity to 100% (25 commands total, covering all 17 CC commands + 8 OC originals).

New commands:

Command	Pattern	Agent	Description
/explain-project	Simple	default	Multi-subagent project architecture explanation
/code-review	Subtask	code-reviewer	Detailed security/quality code review
/test-report	Delegate	implement	Run tests and save report to ./log/test/
/plan-to-checklist	Simple	default	Convert plan to checklist document
/ui-skills	Simple	default	UI/Tailwind/a11y component guidelines
/blog	Delegate	implement	Technical blog article generation
/gemini	Simple	default	Web search via Gemini CLI

How did you verify your code works?

1. YAML frontmatter validated against existing command patterns (bugfix.md, review.md, plan.md)
2. Typecheck: bun turbo typecheck — 13/13 pass
3. Build: smoke test pass

The template writes reports to ./log/test/, but this repo ignores logs/ (see .gitignore) and OpenCode’s built-in ignore patterns also target **/logs/**. Using log/ will likely create unignored artifacts in working trees. Consider switching the output directory to ./logs/test/ (or another already-ignored log path) and keep wording consistent throughout the command.

[Copilot]

$ARGUMENTS is used at the start of a sentence ("$ARGUMENTS narrows scope …"), which will be replaced with the raw arguments at runtime and can produce a nonsensical sentence (e.g., "packages/foo narrows scope …"). Use a literal reference (e.g., wrap as \$ARGUMENTS`) and keep the actual argument injection on the separate $ARGUMENTS` line below (or remove one of the two).
