Command Code API provider for opencode. Use Claude, GPT, Gemini, DeepSeek, Qwen, Kimi, GLM, MiniMax, Step, and other models through a single API key.

This plugin is for Command Code accounts with Provider API access. GOAT is the live-tested baseline; other API-enabled plans can use models their account is entitled to. The $1 Go plan has no Provider API access. The catalog follows the provider-wide model list, so a model appearing in OpenCode does not imply that every account can call it. See GOAT plan details and Provider API docs.

This package keeps a bundled model catalog current via CI. You do not need a local command-code CLI. Catalog patches publish automatically after a green PR merges to main.

This package is based on FanFan4204/opencode-commandcode-provider. That work started from brent-weatherall/opencode-commandcode-provider by Brent Weatherall. Thank you both — FanFan for the OpenCode provider this repo continues, and Brent for the original plugin, catalog extraction.

• Bundled models.json is the default runtime catalog (no local CLI scrape).
• V1 and V2 use their native plugin and provider surfaces. V1 server() fills provider.commandcode and registers API-key auth; V2 setup() registers provider/model transforms and a key/env integration for /connect and opencode auth login.
• Validation at the boundaries via src/schemas.ts (zod): bundled models.json / manifest.json reads, provider availability payloads, and the plugin config file.
• CLI cost extraction can fail without dropping models; official docs fill missing costs, remaining paid gaps use models.dev as a reference price at sync time. Command Code free SKUs stay $0.
• Vision vs text-only comes from the Command Code CLI catalog (inputModalities on every SKU). models.dev only adds extra inputs (video/audio/pdf) when it matches.
• Reasoning effort variants on models that declare reasoningEfforts.
• Release date, family, input limits, model status, vendor context limits, and matched context-price tiers flow through the bundled catalog. V2 gets native release, family, input, status, and tier fields; V1 keeps its supported fields and base prices, with context_over_200k where representable.
• The provider's supported_endpoints metadata chooses each model's API route. Messages is preferred when advertised; otherwise Chat Completions is preferred, and Responses is used only when it is the sole advertised route. This avoids the malformed Responses function-call start event observed on DeepSeek V4.1 Flash #max in OpenCode V2.0.18: response.output_item.added contained a function_call item without its required arguments string. That exact tool-call flow now passes through Chat Completions on V1 and V2. Responses mappings remain available for response-only models, but the current catalog has none. Claude Sonnet 4.6 returned MODEL_NOT_IN_PLAN with the message “available in Pro and above plans or extra on-demand usage”; entitled Claude access has not been live-verified. If a model fails on an account entitled to use it, please open an issue with the model ID and OpenCode version, or submit a PR with a reproducible fix.
• Quiet OpenCode startup (diagnostics go to startup.json, not stdout).

For published plugin versions, the six-hour CI schedule extracts the latest command-code npm bundle and refreshes callable models plus endpoint metadata, even when the CLI version is unchanged. It opens a catalog PR only when generated artifacts change; at startup the plugin loads those artifacts and registers them with OpenCode — never the other way around.

• Extract + filter — model entries (ids, names, reasoning, inputModalities, limits) are evaluated out of the minified CLI bundle (src/catalog.ts), then intersected with the callable IDs reported by the provider API.
• Metadata + costs merge — vendor context length tightens only a fallback context limit, while supported_endpoints selects Messages, Chat Completions, or Responses per model in that preference order; missing endpoint metadata preserves the last known route data. models.dev contributes release date, family, input limit, status, modalities, and cost tiers when present. Tier rows are accepted only when their base prices match this Command Code catalog. Base costs use CLI bundle → official Command Code docs → free SKUs ($0) → models.dev reference prices → unmatched placeholder. Anything still unmatched marks the catalog degraded. This runs at sync time only; runtime never fetches metadata or prices.
• Artifacts — models.json (the catalog), _version.txt (upstream version), manifest.json (counts, per-source cost stats, healthy/degraded/broken status).
• Version-specific registration — V1 uses the plugin config key, direct AI SDK packages, the server() provider map, and its auth callback. V2 uses plugins, OpenCode's native provider runtimes, provider/model transforms, and a commandcode integration with key and COMMANDCODE_API_KEY environment methods. Both retain the Command Code wire model ID. V2 exposes tiered context pricing; V1 emits its supported context_over_200k field and keeps flat pricing for other tiers.
• Degraded/cache fallbacks — a degraded/broken manifest sets the degraded flag with a reason; an unreadable bundled models.json falls back to the last-good cache; auth/connect still registers even with an empty catalog.

OpenCode V2:

{
  "plugins": ["@brainervirus/opencode-commandcode"]
}

OpenCode V1:

{
  "plugin": ["@brainervirus/opencode-commandcode"]
}

The bare package name is unpinned and resolves npm's latest release when OpenCode installs or updates it; adding @latest is unnecessary. OpenCode V2 checks for updates at startup but keeps an existing cached package. Apply a newer package with OpenCode's plugin-update action, then restart to load it. OpenCode V1 can refresh the global package with opencode plugin @brainervirus/opencode-commandcode --global --force.

file:// checkouts are not updated by npm; git pull after CI commits, or switch to the npm plugin line.

On OpenCode V2 the plugin registers the commandcode provider, its models, the native OpenCode runtime, and its API base URL through the V2 provider API. On V1 the server hook fills provider.commandcode defaults — npm: "@ai-sdk/openai-compatible" plus the Provider API baseURL; the plugin package itself is never the SDK npm field. Only add a manual provider entry if you need non-default transport options.

Set COMMANDCODE_API_KEY, or connect interactively. OpenCode V1 provides Command Code through /connect; OpenCode V2 registers key and environment methods for /connect and opencode auth login commandcode. V2 uses OpenCode's automatic provider activation and preserves an explicit activation setting. Connect before running a model; an explicit run while disconnected still returns an authorization error from the API.

/models

Catalog patches ship in new npm releases. OpenCode loads the version in its package cache; an update must be applied through the host before the new catalog appears. If a new model is missing after an announced sync, check the installed package version, apply the update, and restart OpenCode.

Optional, ~/.config/opencode/opencode-commandcode.json (legacy fallback name commandcode-go-opencode-provider.json still loads). Unknown keys are ignored; every field has a default.

Maintainers only. OpenCode will scrape a local command-code install when COMMANDCODE_PACKAGE_PATH or commandCodePackagePath in ~/.config/opencode/opencode-commandcode.json is set.

git clone https://github.com/BrainerVirus/opencode-commandcode.git
cd opencode-commandcode
bun install
bun run check            # oxlint + oxfmt --check + bun test tests/unit/ + tsc (the release gate)

bun run sync -- --remote  # refresh models.json + manifest.json + _version.txt from command-code@latest
bun run build             # bundle src/entry.ts to dist/plugin.js
bun test tests/unit/      # unit suite (also via bun run test)
bun run test:integration  # live-endpoint tests, not part of the gate
bun run verify:release-candidate  # dry-run pack; manifest and package versions must match
bun run generate-readme   # reports catalog counts only; README is hand-edited
bun run catalog:ci        # entry used by the catalog-sync workflow

Entry points: plugin.ts owns both config surfaces (V2 id/setup plus V1 server); index.ts re-exports the plugin plus the createCommandCode SDK factory; src/entry.ts is bundle glue for scripts/build-plugin.ts only — it produces dist/plugin.js.

CI (.github/workflows/catalog-sync.yml) checks every 6 hours for CLI catalog changes and provider availability/endpoint metadata changes; it opens a fix(catalog) PR only when generated files change. If extraction fails or the model-count safety floor is breached, it opens a catalog-break issue and leaves the last-good files intact. The PR auto-merges after check (test), check (typecheck), check (lint), check (format), and check (pack) are green. .github/workflows/release.yml then runs semantic-release (build + verified npm publish + GitHub Release + tag). Do not push to main.

The GitHub Actions secret name is NPMJS. It is mapped to both NPM_TOKEN and NODE_AUTH_TOKEN. Use an npm Automation token (bypasses 2FA). A login token from ~/.npmrc fails CI with EOTP. Catalog PRs get a real CI run when RELEASE_SYNC_TOKEN is a PAT; GITHUB_TOKEN can open the PR but GitHub will not start workflows from that event.
