01
Question shape repair
Stringified `questions`, bare question objects, and stringified `options` get coerced back before OpenCode validates the call.
Archived · source-only OpenCode experiment
Stop tiny tool bugs before they derail the whole agent run.

Failure modes
Four small edges. One bad run.
The source explored boring but expensive failures: tool args that are almost right, nested arrays that models stringify, UI placeholders that models misread, and repeat prompts that bury the original question.
02
Narrow MCP coercion
Only selected schema-like fields are parsed. JSON-looking file bodies, commands, and user content stay untouched.
03
DCP compress repair
Flat compress ranges and stringified range arrays get restored to DCP's native content array before validation.
04
Prompt retry lock
A per-session lock blocks repeated question calls until the user replies, rejects, types a new message, or the safety TTL expires.
