OpenCode 2.2.3 adds a built-in Claude Agent provider that runs Claude models through your own Claude Code login, subscriptions included

OpenCode, the open-source coding agent, shipped v2.2.3 at 09:55 UTC on Oct 30 with a built-in "Claude Agent" provider. After installing Claude Code and running claude auth login, users pick Claude Agent in /connect and can call Claude models through their own Claude Code login, whether that is a subscription, an API key or a cloud account. It runs the user's local claude program through Anthropic's public Claude Agent SDK, but turns off Claude Code's built-in tools and uses OpenCode's own tools and permission system instead. Hours earlier, OpenCode team member dax (@thdxr) teased on X "what if you could use your claude subscription in opencode", drawing about 2,300 likes.

Key Takeaways

v2.2.3 shipped at 09:55 UTC on Oct 30; its first highlight is "Use Claude Code in OpenCode", from PR #58782 (release notes)
Setup is three steps: install Claude Code, run claude auth login, and pick Claude Agent in /connect; OPENCODE_CLAUDE_PATH overrides the claude binary
The design spec says it uses only the public SDK, never reads Claude Code's saved login and never intercepts or changes its requests; subscription, API key and cloud logins all work (spec)
Claude Code's built-in tools, CLAUDE.md, hooks, MCP servers, skills, auto compaction and auto memory are all off; OpenCode's tools, permissions and compaction apply, with one claude process per session that stops after 5 idle minutes
dax's (@thdxr) teaser post drew about 2,300 likes and 280 replies (post); no performance comparison has been published

Cursor launches Agent SDK: agents as code with Markdown prompts, TypeScript tools, built-in evals, and hosted or self-run deployment

On Oct 26 Cursor announced that its Agent SDK is generally available. An agent's system prompt is written in Markdown and its tools in TypeScript; agents can be deployed on Cursor's hosted infrastructure or run on your own machines, and built-in evals measure every change. Cursor's docs say it uses the same Cursor SDK harness that powers Bugbot, Security Review, Approval Bot and Rollouts, can be triggered from source-control events, issue trackers, Slack or schedules, and is managed under Deployed Agents after deployment. Cursor has not published pricing or benchmarks.

Key Takeaways

Same harness: Cursor's docs say Agent SDK runs on the harness behind four of its own agents: Bugbot, Security Review, Approval Bot and Rollouts
Project layout: bot/instructions.md is the required always-on system prompt, each bot/tools/*.ts file is one typed tool, with folders for skills, MCP connections, subagents, channels, hooks and schedules, and evals live in evals/*.eval.ts
Triggers and deployment: runs can be triggered from source control, issue trackers, Slack, webhooks or schedules; deploy on Cursor-managed hosting or self-host, then manage under Deployed Agents
CLI: agent-sdk validate, run and eval check the project, run a real turn and run evals; Cursor says only run and eval need a Cursor credential
Cursor has not published pricing or benchmarks

Claude Code 2.1.302 turns on fork subagents by default across claude -p, Agent SDK, desktop and VS Code; standalone Claude Design closes Dec 14

Claude Code v2.1.302 (Oct 16) makes fork subagents the default in claude -p, the Agent SDK, desktop and VS Code, starts permission-mode-less headless sessions on third-party providers in default mode, and adds CLAUDE_CODE_AUTO_MODE_MODEL. It also flags that standalone Claude Design (claude.ai/design) closes on Dec 14, 2026; design systems must be migrated to Claude Artifacts, while chats and comments are not carried over.

Key Takeaways

Fork subagents now default-on in claude -p, Agent SDK, desktop and VS Code; disable with CLAUDE_CODE_FORK_SUBAGENT=0
Headless sessions with no permission mode on third-party providers start in default mode (telemetry off or fresh install); --permission-mode auto keeps auto
New CLAUDE_CODE_AUTO_MODE_MODEL picks the client-side auto mode classifier model; prompt/agent hooks capped at 12 concurrent per event
Read tool refuses image sources over 128 MB; MCP servers on protocol 2026-07-28 that omit resultType/ttlMs/cacheScope no longer break
Standalone claude.ai/design closes Dec 14, 2026; chats, comments and public links are not migrated and originals are deleted afterward

Anthropic cuts Sonnet 5.5 cache reads to $0.10/MTok, adds $100–$200 monthly API credits to Max, ships Managed Agents automation playbook

Sonnet 5.5 cache hits now cost 0.05x base input ($0.10/MTok), which Anthropic says makes most agentic work ~20% cheaper. Max 5x/20x plans now include $100/$200 in monthly Claude API credits (Team $20–$100 per seat) usable on the API, Managed Agents and Agent SDK, alongside an official reference implementation for scheduled Managed Agents automations.

Key Takeaways

Sonnet 5.5 cache reads $0.20 to $0.10/MTok (0.05x base input); input $2 / output $10 unchanged; Opus 5.5 also 0.05x ($0.20/MTok)
Anthropic says ~20% cheaper on most agentic work; API only, Claude Code limits unchanged
Max 5x gets $100/mo, Max 20x $200/mo; Team $20 (Standard) / $100 (Premium) per seat, pooled up to $500; no rollover
Credits cover Claude API, Managed Agents, Agent SDK and playground, not Claude Code or app extra usage
Managed Agents bills tokens plus $0.08 per session-hour; official daily-brief template sets up via a Claude Code command

LiteLLM open-sources Moyai, a self-hosted cloud coding agent: $101,872 on Devin vs ~$21,700 on Moyai over 31 days (79% cheaper)

On Oct 7 LiteLLM open-sourced Moyai (BerriAI/moyai), the self-hosted background coding agent its team runs daily: tasks from Slack or the browser run in isolated cloud workspaces that edit code, run tests and open PRs. Harnesses (Claude Agent SDK, Codex, Hermes, OpenCode, Deep Agents, Tool Loop) are switchable per session and inference routes through LiteLLM's 100+ providers. LiteLLM says replacing Devin cut a 31-day bill from $101,872 to about $21,700.

Key Takeaways

Cost: $101,872 on Devin vs ~$21,700 on Moyai (~$700/day) over the same 31 days, a claimed 79% / ~$80,172 saving (launch post)
Pluggable harnesses: Claude Agent SDK by default (prompt caching on), plus Hermes, Codex, OpenCode, Deep Agents and Tool Loop (docs)
Inference via LiteLLM across 100+ providers; switch GPT-6 Astra / Claude Opus 5.5 / GLM-5.3 mid-session with per-teammate spend attribution
Provider keys stay server-side and never reach the sandbox; each session gets its own terminal, filesystem and browser
Caveat: ~58 stars at publish time and no LICENSE file detected by GitHub; confirm terms before commercial use

Claude Code 2.1.277: read AGENTS.md when CLAUDE.md is missing

Anthropic staff announced that Claude Code 2.1.277 adds AGENTS.md support: if a project folder has no CLAUDE.md, Claude reads AGENTS.md for project instructions, toggleable under Project instructions in /config. The official changelog lists about 87 CLI changes, including fixing silent hangs in claude -p and Agent SDK sessions after internal errors. The feature is not yet available on Bedrock, Vertex, or Foundry.

Key Takeaways

From 2.1.277, Claude reads AGENTS.md when CLAUDE.md is absent; toggle under /config Project instructions.
Lets teams share AGENTS.md with tools like Codex instead of maintaining two instruction files.
Also fixes silent hangs in claude -p / Agent SDK; notes at github.com/anthropics/claude-code/releases/tag/v2.1.277.
