OpenCode provider
Why it is on the list
Section titled “Why it is on the list”OpenCode ships a coding agent CLI, which is the only qualification this list has. A provider is the identity of a CLI to point at, so the planned set is simply the CLIs people are already running from an editor or a terminal to write code.
The order they are attached in is decided by what each one would teach the contract, not by preference between them.
What is known
Section titled “What is known”That it exists and is worth attaching. This page has no verified facts about the CLI’s interface to report.
What is not known
Section titled “What is not known”Everything else. Not yet investigated:
- The command name and how a conversation is identified.
- Which flags make it a controllable two-way stream.
- Whether its output is NDJSON with a
typediscriminator, which would letEventParserwork unchanged. - Its permission vocabulary, and whether
PermissionModecan express it without a new member. - Whether it has
authandmcpsubcommands, and in what shape.
Where a fact is missing here, it is missing because it has not been checked — not because it was judged unimportant.
What attaching it would contribute
Section titled “What attaching it would contribute”Every port applies pressure to the same two places, and both are findings to raise rather than things to work around:
Auth/andMcp/are currently Claude-shaped. They runclaude auth status --jsonandclaude mcp listand parse what those print. Constructed with a provider’sname, they will run against another CLI and produce nothing useful if it spells its subcommands differently.PermissionModeis a closed set. Its constructor is private precisely so no mode can appear that other adapters cannot spell. A CLI with a concept the set cannot express is evidence that the shared vocabulary needs reshaping, and should be discussed rather than worked around.
Where to go next
