Funny bug - agent rejected even if model is recognized

Description

My subagent was rejected mid work because it's config had mixed-case letters and OpenCode is sometimes case-sensitive.
It even suggested the correct name… then rejected it anyway.

Model config in .opencode/agent/fix.md:

model: OpenRouter/GLM-5.3-Flash

Error:

Model not found: OpenRouter/GLM-5.3-Flash. Did you mean: openrouter?

After printing the suggestion it just… rejects the agent and continues without it.

Expected behaviour (at least one of):

• fallback to the suggested name,
• fallback to the parent model,
• case-insensitive match,
• stop and “error, please fix this”.

Instead we just get a silent failure and a loop of token-wasting mess.

Ladies and gentlemen, behold - Artificial Intelligence!

Steps to reproduce

1. Make a custom sub-agent that sets model: OpenRouter/GLM-5.3-Flash (or any non-canonical casing).
2. Have the main agent call that sub-agent.
3. Watch it print “Did you mean: openrouter?”.
4. Watch and cry when you see it fail because AI tools are defeated by the " OpenRouter vs openrouter " difference.
