OpenCode

Validates the OpenCode project config — opencode.json or opencode.jsonc, at the repository root or under any .opencode/ directory — where a misspelled key is read, ignored and never reported. OpenCode 2.0 renames much of the schema while still loading the 1.x spelling, so both vocabularies are accepted. OpenCode merges agent/agents and command/commands by entry name; only conflicting definitions of one name are reported. Comments and trailing commas are fine — OpenCode reads .json through a JSONC parser. OpenCode reads AGENTS.md for portable instructions, so no OpenCode-specific instruction format is validated. Its commands, agents, skills and repository-local files matched by instructions paths or globs get the shared content rules; remote URLs are not fetched. Enabled automatically wherever an opencode.json or opencode.jsonc exists, or a .opencode/ directory holds OpenCode content.
