Phase A continuation of the ProviderShared dedupe pass. Three more
patterns lifted into ProviderShared so they're written once:
ProviderShared.invalidRequest(message) — replaces six identical
`const invalid = (message) => new InvalidRequestError({ message })`
one-liners across openai-chat, openai-responses, anthropic-messages,
gemini, openai-compatible-chat, and bedrock-converse. Each adapter
keeps a short `const invalid = ProviderShared.invalidRequest` alias
so the 27 callsite `yield* invalid("...")` patterns are unchanged.
Bedrock's SigV4 catch path and the openai-compatible-chat baseURL
guard both go through the helper now too.
ProviderShared.validateWith(decode) — replaces the identical
`(draft) => decode(draft).pipe(Effect.mapError((e) =>
invalid(e.message)))` lambda body in five adapters. Same line count
but shorter, names the pattern, and keeps the `decode → mapError →
InvalidRequestError` translation in one canonical spot.
ProviderShared.jsonPost({ url, body, headers }) — replaces the
five-adapter pattern of `HttpClientRequest.post(url).pipe(setHeaders,
bodyText)` for JSON-body POSTs. Sets `content-type: application/json`
last so caller headers can override everything except the
content-type. Bedrock uses it for both the bearer-auth and SigV4-
signed paths; SigV4 still signs against `baseHeaders` (which already
contained content-type) so the signature matches what the helper
ultimately sends.
Net change: -73 / +86 (+13 in shared.ts mostly JSDoc; -86 across the
six adapters). The `HttpClientRequest` and `InvalidRequestError`
imports are dropped from the five SSE adapters and from Bedrock since
they're no longer referenced directly.
Verified: `bun typecheck` clean, 106 pass / 0 fail / 0 skip
(unchanged).

Installation Directory
The install script respects the following priority order for the installation path:
$OPENCODE_INSTALL_DIR- Custom installation directory$XDG_BIN_DIR- XDG Base Directory Specification compliant path$HOME/bin- Standard user binary directory (if it exists or can be created)$HOME/.opencode/bin- Default fallback
# Examples
OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
Agents
OpenCode includes two built-in agents you can switch between with the Tab key.
- build - Default, full-access agent for development work
- plan - Read-only agent for analysis and code exploration
- Denies file edits by default
- Asks permission before running bash commands
- Ideal for exploring unfamiliar codebases or planning changes
Also included is a general subagent for complex searches and multistep tasks.
This is used internally and can be invoked using @general in messages.

Building on OpenCode
If you are working on a project that's related to OpenCode and is using "opencode" as part of its name, for example "opencode-dashboard" or "opencode-mobile", please add a note to your README to clarify that it is not built by the OpenCode team and is not affiliated with us in any way.
FAQ
How is this different from Claude Code?
It's very similar to Claude Code in terms of capability. Here are the key differences:
- 100% open source
- Not coupled to any provider. Although we recommend the models we provide through OpenCode Zen, OpenCode can be used with Claude, OpenAI, Google, or even local models. As models evolve, the gaps between them will close and pricing will drop, so being provider-agnostic is important.
- Out-of-the-box LSP support
- A focus on TUI. OpenCode is built by neovim users and the creators of terminal.shop; we are going to push the limits of what's possible in the terminal.
- A client/server architecture. This, for example, can allow OpenCode to run on your computer while you drive it remotely from a mobile app, meaning that the TUI frontend is just one of the possible clients.
